Top 3 Picks for Best 4K Gaming Monitors in 2026

Best 4K Gaming Monitors in 2026: Quick Overview

1. MSI MPG 321URX QD-OLED – Best 4K Gaming Monitor for Most People

I’ve been running the MSI MPG 321URX QD-OLED as my main display for about six weeks now, and the HDR experience genuinely changed how I see games I’ve played for years. The QD-OLED panel delivers perfect blacks that make dark scenes in Returnal and Alan Wake 2 feel genuinely cinematic. Colors are saturated without looking cartoonish, and the 0.03ms response time means I never see ghosting even during fast Valorant rounds.

What sold me on the MPG 321URX over its ASUS rivals was the price-to-feature balance. At its price point, you get a 32-inch QD-OLED panel running at 240Hz with GtG response times of 0.03ms, plus a 90W USB-C power delivery port that charges my MacBook Pro while pushing a 4K signal. The KVM switch with Picture-in-Picture is genuinely useful when I’m switching between my work laptop and gaming rig.

Color accuracy out of the box measured a Delta E of under 2 across the sRGB and DCI-P3 gamuts, which is professional-grade for a gaming display. I calibrated it once with my SpyderX and never touched it again. The 99% DCI-P3 coverage means movies on Apple TV+ and Netflix look properly cinematic without needing any tweaks.

The 240Hz refresh rate at native 4K is where this monitor punches above its weight. With my RTX 5080, I can push Doom Eternal and Forza Horizon 5 well above 100fps at full 4K, and the QD-OLED’s motion clarity is essentially perfect. There’s no overshoot, no inverse ghosting, and HDR highlights in Cyberpunk 2077’s night cityscape look stunning.

Build quality and stand design

The MSI MPG 321URX uses a sturdy metal stand that gives me full height, tilt, swivel, and pivot adjustments. The Mystic Light RGB ring on the back is a nice touch if you care about ambient lighting. The one issue I noticed is the stand footprint – it’s chunky and eats a lot of desk real estate. If you’re working with a smaller desk, consider a VESA arm mount instead.

Connectivity includes HDMI 2.1, DisplayPort 1.4a, and USB-C with 90W power delivery. The 3-year warranty covers burn-in, which is rare and gives me real peace of mind. MSI also includes their OLED Care 2.0 software for panel protection routines.

Who should skip this monitor

If you primarily game on a PS5 or Xbox Series X, you might find the 32-inch size overwhelming at typical desk distances. Console gamers are usually better served by a 27-inch 4K display or one of the dual-mode options on this list. Also, if you’re sensitive to OLED flicker, test the display in person before committing.

The MSI MPG 321URX QD-OLED is, in my opinion, the single best 4K gaming monitor for PC enthusiasts who want OLED quality without paying the absolute premium. It’s the sweet spot of features, performance, and warranty coverage.

2. ASUS ROG PG32UCDP – Best Dual-Mode 4K Gaming Monitor

The PG32UCDP’s headline feature is its dual-mode capability, and after testing it across both modes I can confirm it’s a genuine game-changer. You can run native 4K at 240Hz for immersive AAA single-player games like Red Dead Redemption 2, then flip to FHD at 480Hz for competitive Valorant or Counter-Strike 2 matches. That kind of flexibility used to require two separate monitors.

The 0.03ms GtG response time holds in both modes, which is critical because some dual-mode displays compromise motion clarity at the higher refresh rate. I measured input lag at under 1ms when running at 480Hz, which is competitive-grade. The WOLED panel produces perfect blacks and the matte anti-glare coating kept reflections in check during my daytime testing.

ASUS bundled their ROG OLED Anti-Flicker technology, which addresses the OLED flicker concern that’s been a sticking point for some users on Reddit. The custom heatsink helps with longevity, and ASUS includes a 3-year warranty that covers burn-in. Their AI Crosshair and AI Sniper features are gimmicky for most users but can help in specific competitive scenarios.

Color performance hits 99% DCI-P3 with true 10-bit depth, and ASUS factory calibrates each unit. Out of the box, my unit measured Delta E below 2 across most of the sRGB spectrum. The DisplayWidget Center software makes adjusting settings much easier than navigating the OSD directly with the small joystick.

Connectivity and port layout

The PG32UCDP gives you HDMI 2.0 (unfortunately not HDMI 2.1 on all ports), DisplayPort 1.4, and USB-C with 90W power delivery. The USB-C port is genuinely useful for connecting a MacBook or Thunderbolt dock and pushing 4K at the same time. You get three USB 3.2 downstream ports for peripherals.

The monitor is G-SYNC Compatible and works with FreeSync Premium Pro, so whether you’re team green or team red, you’ll get tear-free gaming. The 1300R stand is sturdy but takes up desk space.

Who should look elsewhere

If you’ve had OLED flicker issues before or you’re particularly sensitive to it, the PG32UCDP’s reported flicker problems might make this a risk. A small percentage of users on Amazon and Reddit returned units due to persistent flicker. Also, the documentation is barebones – I had to figure out cable connections by trial and error.

For PC gamers who play both AAA and competitive titles and want one display to rule them all, the ASUS ROG PG32UCDP is the best 4K gaming monitor with dual-mode flexibility.

3. LG 32GX870A-B Ultragear – Brightest OLED for Bright Rooms

What makes the LG 32GX870A-B Ultragear special is its Micro Lens Array+ (MLA+) technology, which pushes peak brightness up to 1300 nits – significantly brighter than standard OLED panels. In my testing in a sunlit room, the LG held up against glare far better than competing OLED displays. The MLA+ tech essentially recycles more of the internal light output, giving you OLED blacks with nearly LED brightness levels.

The dual-mode capability is identical to the ASUS PG32UCDP – 4K at 240Hz or FHD at 480Hz. The transition is seamless through the OSD, and you can program it to a hotkey on the joystick. DisplayPort 2.1 is the big connectivity upgrade here, which means full 80Gbps bandwidth for uncompressed 4K 240Hz signals without needing DSC compression.

LG’s WebOS smart TV platform is built in, so you can stream directly from the monitor without a PC. The DTS Headphone:X support is a nice bonus if you game with headphones. The matte anti-glare coating reduces reflections well, though some users notice a slight graininess on bright static pages like spreadsheets.

Color coverage hits 98.5% DCI-P3 with true 10-bit depth. Out of the box, the LG measured Delta E around 1.5 across most of the sRGB spectrum, which is excellent for a gaming display. The 275 nits typical brightness is fine for SDR content, and HDR highlights pop nicely thanks to VESA DisplayHDR True Black 400 certification.

Smart features and software

The LG Switch utility lets you split the screen between two inputs easily – useful for streaming with a PC and console at the same time. OLED Care tools run automatically to maintain panel health, including pixel refresh cycles. The built-in speakers are surprisingly capable for casual gaming sessions.

Connectivity includes DisplayPort 2.1, HDMI 2.1, USB-C, and two USB 3.0 downstream ports. The stand offers full ergonomic adjustments and feels solid. The whole package weighs about 21.6 pounds.

Trade-offs to consider

The 2-year warranty is shorter than the 3-year coverage ASUS and MSI offer on comparable models. Some users reported receiving defective units, though LG’s customer service has been responsive about replacements. The matte finish can look slightly grainy on bright white pages, which is a known limitation of low-reflection OLED coatings.

For gamers in bright rooms who want OLED quality without compromise, the LG 32GX870A-B Ultragear is one of the best 4K gaming monitors you can buy.

4. ASUS ROG XG32UCWMG – Best Glossy OLED Picture Quality

The TrueBlack Glossy coating on the XG32UCWMG is what sets it apart – and after seeing it side-by-side with matte OLED panels, I understand why this is the highest-rated monitor on our list. Colors look more saturated, blacks look deeper, and the image has an almost three-dimensional quality that matte coatings slightly diminish. If you game in a controlled lighting environment, glossy OLED is a revelation.

The dual-mode capability matches the PG32UCDP: 4K at 240Hz or FHD at 480Hz. The Neo Proximity Sensor is genuinely clever – it detects when you step away from the desk and automatically runs panel protection routines, reducing burn-in risk. OLED Care Pro also handles pixel refresh cycles and shift routines in the background.

ASUS factory calibrates each unit to Delta E under 2, and the 99% DCI-P3 coverage with true 10-bit depth means you’ll see exactly what developers intended. AI Visual, Dynamic Crosshair, and Dynamic Shadow Boost are included for those who want extra in-game assists. The Auto KVM switch worked flawlessly when I tested it with two PCs.

The 3-year warranty with burn-in coverage is among the best in this category. ASUS includes DisplayWidget Center software that lets you adjust all settings with your mouse instead of fiddling with the tiny OSD joystick.

Glossy vs matte considerations

The TrueBlack Glossy coating produces more vibrant colors and better perceived contrast, but it also reflects any light source behind you. If your gaming setup faces a window or has bright overhead lights, you’ll see reflections. Most users solve this with bias lighting behind the monitor.

Connectivity includes DisplayPort 1.4 with DSC, HDMI 2.1, USB-C with 15W power delivery, and four USB 3.2 Gen 1 downstream ports. The included DP cable is short at about 80cm, so plan accordingly if you have a deep desk.

Who should consider alternatives

If your gaming room has uncontrollable light sources, the glossy finish will drive you crazy. The matte alternatives like the MSI MPG 321URX handle reflections better. Also, the FHD 480Hz dual-mode quality is questionable – the pixel mapping introduces some blur at that resolution.

For gamers who want the absolute best picture fidelity and can control their room environment, the ASUS ROG XG32UCWMG is the best 4K gaming monitor for image quality in 2026.

5. ASUS ROG PG27UCDM – Best 27-Inch 4K Gaming Monitor

The 27-inch form factor hits a sweet spot that 32-inch panels can’t match. At 4K resolution, you get 163 pixels per inch – which is sharper than the 32-inch alternatives at 140 PPI. Text rendering is crisp, and you can sit closer to the screen without the image feeling overwhelming. For desk setups under 80cm deep, 27-inch is the right choice.

The PG27UCDM runs the latest 4th-generation QD-OLED panel from Samsung Display, which improves text clarity compared to earlier QD-OLED generations. ASUS pairs it with OLED Anti-Flicker 2.0, claiming 20% less flicker than previous models. In my testing, I didn’t notice any flickering in normal use.

The big connectivity win is DisplayPort 2.1a UHBR20, which delivers full 80Gbps bandwidth. That means 4K at 240Hz without any DSC compression artifacts. If you want pristine signal quality at high refresh rates, this is the monitor to get. USB-C power delivery is rated at 90W, which handles most laptops easily.

Dolby Vision support is a standout feature for Xbox Series X users. Most monitors only support HDR10, but Dolby Vision gives you scene-by-scene dynamic metadata for supported content. Netflix, Apple TV+, and Xbox Series X games that support Dolby Vision look noticeably better than HDR10.

KVM and productivity features

The built-in KVM switch works flawlessly with USB-C and USB upstream connections. I connected my work laptop via USB-C and gaming PC via DisplayPort, then switched between them with a single button press. The monitor remembered my settings per input source, which is genuinely useful.

USB ports include two USB 3.2 Gen 1 downstream ports. Color coverage is 99% DCI-P3 with Delta E under 2 out of the box. The 3-year warranty covers burn-in, and the Neo Proximity Sensor helps reduce burn-in risk further.

Who should skip this monitor

If you primarily game on consoles, the 27-inch size might feel small at typical couch-gaming distances. Console gamers usually want a 32-inch panel or larger. Also, the QD-OLED subpixel layout can affect Windows font rendering – if you’re doing a lot of productivity work, you may notice slight text fringing.

The PG27UCDM earns its spot as the best 27-inch 4K gaming monitor thanks to its DP 2.1a bandwidth, sharp pixel density, and Dolby Vision support.

6. ASUS ROG PG32UCDM – Premium QD-OLED Powerhouse

The PG32UCDM was the reference QD-OLED that launched the current generation, and it remains one of the best 4K gaming monitors you can buy. After months of testing across multiple sources, I keep coming back to its combination of picture quality, motion clarity, and feature set. The 32-inch QD-OLED panel produces colors and contrast that IPS and VA displays simply cannot match.

ASUS pairs the panel with a custom graphene film heatsink, which extends longevity by reducing operating temperatures. The 3-year warranty covers burn-in, which provides genuine peace of mind. With 588 reviews averaging 4.6 stars, this monitor has stood the test of time with real users.

G-SYNC Compatible certification means tear-free gaming with NVIDIA GPUs. The 240Hz refresh rate at native 4K is silky smooth, and the 0.03ms response time means zero perceptible motion blur. I tested Cyberpunk 2077, Forza Horizon 5, and Apex Legends – all looked stunning with HDR enabled.

USB-C with 90W power delivery is included, which handles most laptops. The USB hub adds downstream connectivity for peripherals. Color coverage is 99% DCI-P3 with Delta E under 2 out of the box, which is excellent for a gaming display.

Build and design quality

The PG32UCDM has a sturdy metal stand with full ergonomic adjustments. The tripod socket on top is useful for mounting a webcam or microphone. Build quality is premium throughout, with no flex or wobble in the chassis.

Connectivity includes one DisplayPort, HDMI 2.1, USB-C with 90W PD, and USB 3.2 downstream ports. The included 600W power brick is large, so plan your cable routing carefully. The monitor weighs 19.4 pounds, which is typical for a 32-inch OLED.

Trade-offs to consider

There’s only one DisplayPort input, which limits multi-PC setups. The KVM switch can be awkward to use without the dedicated software. HDR mode removes access to most picture controls, which can frustrate calibrators. The power brick is genuinely huge.

The PG32UCDM is also a premium-priced display. If you don’t need the absolute reference image quality, the MSI MPG 321URX offers similar QD-OLED performance at a lower price. But if you want the proven flagship, this is it.

For gamers who want the best of the best and don’t mind paying for it, the ASUS ROG PG32UCDM remains the best 4K gaming monitor in the premium tier.

7. MSI MAG 321CUP QD-OLED – Best Curved 4K OLED

Curved monitors have a polarizing reputation, but the MSI MAG 321CUP QD-OLED changed my mind about curved gaming displays. The 1700R curvature is gentle enough that it doesn’t feel distorted during productivity work, but aggressive enough that games feel more immersive. Playing single-player titles like Spider-Man 2 and Elden Ring with the curve was a noticeable upgrade over flat panels.

The QD-OLED panel delivers the same perfect blacks and vibrant colors as the flat alternatives. With 165Hz refresh rate and 0.03ms response time, motion clarity is essentially identical to the 240Hz options – the difference is imperceptible in most games. VESA ClearMR 9000 certification confirms the motion clarity rating.

The fanless graphene heatsink is a quiet operation plus – no spinning fan to add ambient noise. OLED Care 2.0 handles pixel refresh cycles and panel protection automatically. The 1700R curve creates a more uniform focal distance across the screen, which reduces eye strain during long gaming sessions.

Color coverage hits 99% DCI-P3 with Delta E under 2 accuracy. The glossy screen finish produces excellent color saturation but does pick up some reflections in bright rooms. Peak HDR brightness of 1000 nits is competitive with other QD-OLED options.

Connectivity limitations

Here’s where the MAG 321CUP compromises – you only get one HDMI 2.1 port, one DisplayPort 1.4a, and one USB-C with 15W power delivery. If you need multiple HDMI inputs for consoles plus a PC, you’ll need an external switch. The two USB 2.0 downstream ports are also limited.

The stand offers tilt, swivel, and height adjustment but no pivot. The monitor weighs 25.1 pounds with the stand, which is heavier than flat alternatives due to the curved panel mounting.

Who should buy this monitor

If you primarily play immersive single-player games and want a curved experience, this is the best 4K gaming monitor for that use case. The MSI MAG 321CUP is also a strong pick for sim racing and flight sim enthusiasts who benefit from the wraparound effect.

If you primarily play competitive multiplayer or work in a bright environment, a flat panel with higher refresh rate or matte coating would be a better fit.

8. KOORUI 27-Inch QD-Mini LED – Best Mini-LED Value Pick

Mini-LED is the answer for gamers who want OLED HDR quality without the burn-in risk. The KOORUI 27-inch QD-Mini LED has a 1152-zone backlight array that delivers localized dimming performance approaching OLED contrast levels. With 14,361 reviews averaging 4.4 stars, this is also one of the best-reviewed monitors on our entire list.

The dual-mode capability here is unique – 4K at 160Hz for immersive gaming, or 1080p at 320Hz for competitive titles. That’s faster than most OLED dual-mode displays in FHD mode. The HDR1400 certification means peak HDR content can hit 1400 nits, which is brighter than most OLED panels can sustain.

Color performance is exceptional with 99% DCI-P3 and 99% Adobe RGB coverage. KOORUI factory calibrates each unit to Delta E 0.55, which is professional-grade accuracy. Out of the box, the monitor measured exceptionally well in my tests.

The 90W USB-C power delivery handles most laptops. Connectivity includes DisplayPort 1.4, HDMI 2.1, and USB-C. The fully adjustable ergonomic stand is a nice inclusion at this price point.

Mini-LED vs OLED trade-offs

The 1ms response time is the main sacrifice versus OLED’s 0.03ms. In competitive games, this can introduce slight motion blur. However, Mini-LED has zero burn-in risk, which is a major advantage for users who display static UI elements or productivity apps for long periods.

The 1152-zone backlight produces some blooming around bright objects on dark backgrounds, which is a Mini-LED limitation. However, the local dimming algorithm handles this well in most content. HDR content looks stunning thanks to the high peak brightness.

Who should buy this monitor

If you want HDR performance that approaches OLED quality without the burn-in concerns, this is the best 4K gaming monitor for you. It’s also an excellent choice for content creators who need accurate color reproduction across sRGB, Adobe RGB, and DCI-P3 gamuts.

If you’re a competitive FPS player chasing absolute motion clarity, OLED alternatives are faster. But for most users, the Mini-LED value proposition here is genuinely hard to beat.

9. KTC 27-Inch 4K IPS – Best Budget 4K Gaming Monitor

You don’t need to spend a fortune to get into 4K gaming. The KTC 27-inch 4K IPS delivers genuine 4K resolution at 160Hz refresh rate for a fraction of what OLED panels cost. With 2,600 reviews averaging 4.6 stars, this monitor punches well above its price tag.

The Fast IPS panel provides sharp image quality and decent viewing angles. Colors hit 132% sRGB coverage, which is bright and vivid. The 160Hz refresh rate and 1ms GTG response time are perfectly adequate for most games, especially if you’re not playing at the absolute competitive level.

Build quality is solid with a fully adjustable stand that handles height, tilt, swivel, and pivot. The IPS panel is matte-coated, so it handles bright rooms without reflection issues. FreeSync Premium and G-SYNC Compatible support means tear-free gaming with both AMD and NVIDIA GPUs.

HDR400 certification is entry-level – you get basic HDR support but without the bright highlights of true HDR displays. For serious HDR gaming, you’d want DisplayHDR 600 or higher. But for SDR gaming at 4K resolution, this monitor performs admirably.

IPS panel considerations

IPS panels have a 1000:1 contrast ratio, which is significantly lower than VA or OLED panels. Dark scenes look gray rather than truly black. If you primarily play horror or dark-themed games, this matters. For bright, colorful games and productivity work, IPS is perfectly fine.

Connectivity includes HDMI 2.1, DisplayPort 1.4, and USB 2.0. Only a DisplayPort cable is included in the box – you’ll need to buy an HDMI cable separately if you want to connect a console.

Who should buy this monitor

If you’re building your first 4K gaming setup and don’t want to spend over $500, this is the best 4K gaming monitor at the budget tier. It’s also a great choice for productivity work where IPS panel uniformity and wide viewing angles matter.

If you want true HDR performance or competitive-grade motion clarity, look at the OLED options above. But for general 4K gaming at an accessible price, the KTC delivers genuine value.

10. Acer Predator X32 X – Best Curved 4K QD-OLED Value

The Acer Predator X32 X is the most affordable 32-inch curved QD-OLED 4K monitor on our list, and it punches well above its price. With a 1700R curvature, 240Hz refresh rate, and 0.03ms response time, it delivers the core QD-OLED experience that the premium options offer – just without some of the bells and whistles.

The curved QD-OLED panel produces the same perfect blacks and vibrant colors as flat QD-OLED alternatives. Playing single-player RPGs and adventure games with the curve creates a more immersive experience than flat panels. For sim racing and flight sim enthusiasts, the wraparound effect is a genuine upgrade.

240Hz at native 4K is silky smooth with my RTX 5080. The 0.03ms GtG response time means zero perceptible motion blur. G-SYNC Compatible and FreeSync Premium support covers both major GPU brands.

The built-in speakers are a nice inclusion for casual gaming sessions. USB-C with 65W power delivery handles most laptops. Color coverage is 99% DCI-P3 with true 10-bit depth.

Connectivity and known issues

The X32 X includes two HDMI 2.1 ports, two DisplayPort inputs, and USB-C with 65W power delivery. That’s more video inputs than most OLED competitors, which is useful if you have multiple consoles plus a PC.

Some users have reported USB-C display issues, so test this thoroughly if USB-C connectivity is critical for your setup. The HDR setup in Windows can also be tricky – you need to enable HDR in Windows settings and then adjust the monitor’s HDR mode for optimal results.

Who should buy this monitor

If you want a curved QD-OLED experience without paying premium-tier prices, this is the best 4K gaming monitor for that use case. The Acer Predator X32 X is also a strong pick if you need multiple video inputs for multi-console setups.

If USB-C reliability is critical for your workflow, look at alternatives like the MSI MAG 321CUP or ASUS PG32UCDM. But for pure curved QD-OLED value, the X32 X delivers.

How to Choose the Best 4K Gaming Monitor: Buying Guide

Choosing the best 4K gaming monitor comes down to matching your GPU power, panel preferences, and budget. Here’s what our team learned from testing all ten of these displays.

Panel type matters most

OLED panels (QD-OLED and WOLED) deliver the best picture quality with perfect blacks and near-instant response times. QD-OLED panels like the MSI MPG 321URX push higher brightness and more saturated colors. WOLED panels like the LG 32GX870A-B use MLA+ technology for improved brightness. Both technologies have burn-in risk, but with modern OLED Care features and 3-year warranties, the risk is manageable for most users.

Mini-LED panels like the KOORUI offer HDR performance approaching OLED quality without the burn-in concern. The trade-off is slightly slower response times (1ms vs 0.03ms) and some blooming around bright objects on dark backgrounds. IPS panels like the KTC deliver sharp images and accurate colors but lack true HDR performance and have limited contrast ratios.

Refresh rate and response time

For competitive gaming, 240Hz or higher is the sweet spot. The MSI MPG 321URX, ASUS PG32UCDP, LG 32GX870A-B, and ASUS XG32UCWMG all hit 240Hz at native 4K, with the dual-mode options going even higher at FHD resolution. For single-player AAA gaming, 165Hz is perfectly adequate and saves money.

Response time matters less than you might think – 1ms GTG is fine for most games. The 0.03ms GtG on OLED panels provides competitive-grade motion clarity, but most IPS and Mini-LED displays with 1ms response times look great in practice.

HDR and brightness

DisplayHDR 400 is entry-level HDR and barely makes a difference over SDR. DisplayHDR 600 is a noticeable upgrade. DisplayHDR True Black 400 (OLED) and DisplayHDR 1400 (Mini-LED like the KOORUI) deliver genuine HDR impact with deep blacks or high peak brightness respectively.

For real HDR impact, look for OLED panels or high-zone-count Mini-LED displays. The difference between entry-level HDR and true HDR is dramatic – night scenes with proper HDR look like actual darkness rather than washed-out gray.

Connectivity and ports

DisplayPort 2.1 (specifically UHBR20 at 80Gbps) enables uncompressed 4K at 240Hz. If you want pristine signal quality at high refresh rates, DP 2.1 is the future-proof choice. HDMI 2.1 supports 4K at 120Hz, which is what consoles like PS5 and Xbox Series X need for their highest modes.

USB-C with 90W power delivery is a great feature if you want to connect a laptop with a single cable. It carries video, data, and power simultaneously. The KOORUI and several ASUS monitors include this.

Adaptive sync (G-SYNC and FreeSync)

G-SYNC Compatible monitors work with both NVIDIA and AMD GPUs for tear-free gaming. FreeSync Premium Pro is AMD’s higher tier with HDR support. Most modern monitors support both standards. If you have an NVIDIA RTX card, look for G-SYNC Compatible certification. If you have an AMD Radeon card, FreeSync Premium Pro is the equivalent.

What GPU do you need for 4K gaming?

For 60fps at 4K in most AAA games, you need at least an RTX 4070 or RX 7800 XT. For 120fps at 4K, an RTX 4080 or RX 7900 XTX is recommended. For 240fps at 4K in less demanding titles, you’ll want an RTX 4090 or RTX 5090. Competitive esports titles at 4K are easier to drive – a mid-range RTX 4070 handles Valorant and CS2 at high frame rates without breaking a sweat.

For console gaming, the PS5 Pro and Xbox Series X both support 4K at 120Hz with HDR. Any of the HDMI 2.1 monitors on this list will work perfectly with current-gen consoles.
