That means tear-free gaming on consoles and buttery-smooth frame rates on PC. Not every monitor with an HDMI port supports the full spec, though, and that’s where this guide comes in.

Whether you’re a console gamer looking for the perfect PS5 monitor, a content creator needing accurate colors, or a competitive player chasing every frame, the monitors below cover the full range. If you want to explore more options, check out our guides on best 4K monitors and best 4K monitors with high refresh rate.

Top 3 Picks for Best 4K Monitors with HDMI 2.1

Best 4K Monitors with HDMI 2.1 in 2026

1. ASUS ROG Swift PG32UCDM – Best Overall 4K HDMI 2.1 Monitor

The ASUS ROG Swift PG32UCDM is the monitor I keep coming back to. After testing it across PS5, Xbox Series X, and a high-end PC over several weeks, this 32-inch QD-OLED delivers the best combination of image quality, speed, and features available right now. The 240Hz refresh rate at native 4K resolution paired with a 0.03ms response time makes every game look phenomenal.

What sets this apart from other OLED monitors is the graphene-film heat management system. OLED panels are sensitive to heat, and the PG32UCDM’s advanced cooling keeps the panel stable during marathon sessions. The 99% DCI-P3 color gamut and Delta E under 2 accuracy mean creators can trust the colors they see. I tested it side-by-side with a reference monitor and the difference was negligible.

The built-in KVM switch lets you toggle between a desktop and laptop with one button, and the 90W USB-C power delivery charges most laptops while displaying. VRR support works flawlessly with both PS5 and Xbox Series X, and the DisplayHDR 400 True Black certification ensures HDR content pops without washing out dark scenes.

Console Gaming Performance

I connected my PS5 and Xbox Series X simultaneously. Both consoles recognized the monitor immediately and enabled 4K 120Hz output without any firmware updates or cable swaps. The ALLM feature automatically switched to game mode, cutting input lag to under 5ms. For competitive console gaming, this is as good as it gets on a 32-inch screen.

PC Gaming and Productivity

On PC with an RTX 4080, I hit 240Hz in Overwatch 2 and maintained 144Hz+ in Cyberpunk 2077 with DLSS enabled. The 32-inch size at 4K gives you roughly 138 PPI, which is sharp enough for text work without scaling. If you want even higher pixel density for coding, check out our best 4K monitors for coding guide.

2. MSI MAG 321CUP QD-OLED – Best Value QD-OLED

The MSI MAG 321CUP QD-OLED surprised me. At its price point, getting a 32-inch curved QD-OLED panel with 165Hz, 0.03ms response time, and genuine 99% DCI-P3 coverage felt like a steal. The 1700R curvature adds immersion without being distracting, and I found myself preferring the slight wrap for racing games and RPGs.

MSI’s graphene heatsink is the real story here. Unlike monitors with active fans that can whine or fail, this fanless design passively keeps the QD-OLED panel cool. After running it for 8 hours straight during a Baldur’s Gate 3 session, the panel showed no signs of image retention. The VESA ClearMR 9000 certification also validates its motion handling, which is a step above many competitors.

Connectivity includes HDMI 2.1 with CEC support, DisplayPort 1.4a, and USB-C with 15W power delivery. The USB-C wattage is low for charging laptops but works fine for display output. The monitor also includes MSI’s OLED Care 2.0 system with pixel shift and screen saver features to minimize burn-in risk over time.

HDR and Color Performance

The VESA DisplayHDR True Black 400 certification means deep, inky blacks with HDR content. I measured peak brightness around 1,000 nits in small highlight areas, which is impressive for this tier. Color accuracy out of the box was excellent with Delta E under 2, though I’d recommend a quick calibration pass for professional photo work.

Curved Panel Considerations

The 1700R curve is subtle enough that flat-panel purists probably won’t mind. Text remains sharp across the screen, and the curve actually reduces perceived distortion at the edges. If you sit 2-3 feet from your monitor, the curvature adds depth. For competitive FPS where flat screens are preferred, consider the flat 27-inch options on this list instead.

3. ASUS ROG XG27UCDMG – Best Premium 27-Inch QD-OLED

If you want the absolute best 27-inch 4K gaming monitor with HDMI 2.1, the ASUS ROG XG27UCDMG is it. This is the first monitor I’ve tested with ASUS’s 4th-generation QD-OLED technology, and the improvements are visible. Colors are more saturated, the panel is brighter, and ASUS claims a longer lifespan compared to earlier QD-OLED generations.

The standout feature is the Neo Proximity Sensor. When you walk away from the monitor, it dims the screen and activates a screensaver to prevent burn-in. Walk back and it wakes instantly. It sounds gimmicky, but after using it daily for a month, I found it genuinely useful for OLED peace of mind, especially if you leave your monitor on with static desktop icons.

The 27-inch form factor at 4K gives you approximately 163 PPI, which is noticeably sharper than the 32-inch models. Text rendering is crisp, and the pixel density means you can sit closer without seeing individual pixels. The OLED Anti-Flicker 2.0 technology reduces flicker by 20% compared to previous generations, which helps during long sessions.

Gaming Experience at 240Hz

Hitting 240Hz at 4K requires serious GPU power, but the monitor handles it beautifully. With an RTX 4090, I consistently hit the refresh rate ceiling in esports titles and maintained 120-160Hz in demanding AAA games with settings maxed. The ELMB Sync feature works alongside VRR, eliminating both tearing and blur simultaneously.

Build Quality and Design

The stand includes a phone holder and tripod mount, which is a nice touch for streamers and content creators. The overall design is sleek and minimal, fitting into both gaming and professional setups. The glossy coating delivers punchier colors than matte alternatives but requires regular cleaning to look its best.

4. LG 27G810A-B UltraGear – Best Dual-Mode Monitor

The LG 27G810A-B UltraGear offers something unique: genuine dual-mode operation at 4K 180Hz or FHD 360Hz. For gamers who switch between competitive shooters and story-driven titles, this flexibility is unmatched. I used 4K 180Hz for Hogwarts Legacy and dropped to FHD 360Hz for Valorant, and both modes delivered excellent performance.

LG’s panel quality is immediately apparent. The 95% DCI-P3 coverage and DisplayHDR 400 certification produce vibrant, accurate colors that hold up against more expensive IPS monitors. The 1ms GtG response time with minimal overshoot keeps fast motion clean, and the variable overdrive adjusts automatically based on your current refresh rate.

The full ergonomic stand offers height, tilt, swivel, and pivot adjustments. Build quality is excellent, with no wobble or flex. The included 4-pole jack supports DTS HP:X spatial audio, which is a bonus for headphone users. The monitor also includes Dynamic Action Sync for reduced input lag and a Black Stabilizer for visibility in dark scenes.

Who Benefits from Dual Mode

If you play both competitive FPS games and immersive single-player titles, dual mode eliminates the need for two monitors. The 360Hz FHD mode is genuinely useful for esports, where frame rate matters more than resolution. The 180Hz 4K mode handles everything else beautifully. The mode switch takes about 2 seconds through the OSD.

Noise and Fan Considerations

The internal fan is audible in a quiet room. During gaming sessions with speakers or headphones, I never noticed it. In a silent office environment for productivity work, the fan hum is perceptible. If fan noise bothers you, the fanless OLED options on this list may be a better fit.

5. KOORUI G2741L – Best Budget Dual-Mode Monitor

The KOORUI G2741L has become one of the most popular budget 4K monitors with HDMI 2.1, and after using it for several weeks, I understand why. It delivers a genuine dual-mode experience at 4K 160Hz or FHD 320Hz with a Fast IPS panel and 1ms response time. At its price point, the value proposition is hard to beat.

The 95% DCI-P3 color gamut produces rich, saturated colors that look great for gaming and media consumption. HDR400 support adds a modest boost to highlight brightness, though this isn’t a true HDR experience like the OLED monitors on this list. The ergonomic stand with height, tilt, and pivot adjustment is a welcome inclusion at this price point, saving you the cost of a monitor arm.

With over 14,000 reviews and a 4.4 average rating, the G2741L has a proven track record. Most users report no dead pixels and reliable performance. The OSD button placement can cause accidental mode switches, which is a minor annoyance. A DisplayPort cable is included in the box, which is appreciated since some budget monitors ship with only an HDMI cable.

Console Compatibility

I tested with PS5 and Xbox Series X, and both consoles output 4K 120Hz without issues. VRR worked correctly on both platforms. The 160Hz ceiling is more than enough for consoles, which max out at 120Hz. For PC users, the FHD 320Hz mode is excellent for competitive games like CS2 and Valorant.

Longevity and Reliability

Some users report longevity issues appearing after two or more years of use. Budget brands sometimes have tighter margins on component quality, which can affect long-term reliability. The included 1-year warranty is shorter than what established brands offer. If you’re okay with potentially replacing the monitor every few years, the savings are substantial.

6. SANSUI ES-G27D1U – Best for Console Gaming

The SANSUI ES-G27D1U stands out for console gamers because of its connectivity: two HDMI 2.1 ports and two DisplayPort 1.4 inputs. That means you can connect a PS5, Xbox Series X, and a PC simultaneously without any switchers. I set up exactly this configuration and switching between inputs was instant.

The AI-enhanced gaming features include a customizable crosshair overlay, sniper scope zoom, and night vision mode for dark games. These are software-based enhancements that some competitive players will appreciate. The built-in speakers are convenient for casual use, though they lack bass and volume for serious gaming. The AI DBL Eye Care technology reduces blue light without noticeably shifting colors.

At 27 inches with a Fast IPS panel, the ES-G27D1U delivers 4K at 160Hz with a 1ms response time. The DCI-P3 coverage at 93% is slightly below the best IPS panels, but the sRGB 126% coverage ensures vibrant colors for gaming. HDR400 support provides a mild brightness boost for HDR content.

Multi-Console Setup

Having two HDMI 2.1 ports is genuinely useful for console gamers who own both current-gen systems. The monitor’s input switching is fast, and CEC support means your console can wake the monitor automatically. If you need even more flexibility, our best budget monitors with HDMI 2.1 guide covers more options.

Ergonomics and Adjustability

The full ergonomic stand with pivot, swivel, and height adjustment is impressive at this price. The pivot bracket could be sturdier, and I’d be careful when rotating the screen to portrait mode. Otherwise, the stand is stable and allows precise positioning for any desk setup.

7. Amzfast AMZG32C3U – Best for Immersive Gaming

The Amzfast AMZG32C3U is a 32-inch curved VA panel with a 1500R curvature and a 3000:1 contrast ratio. The deep blacks and rich contrast make games look dramatically better than on typical IPS monitors, especially in dark environments. I played through Alan Wake 2 on this monitor and the atmospheric lighting was stunning.

The 120Hz refresh rate at 4K over HDMI 2.1 with VRR support covers the full capability of PS5 and Xbox Series X. The AI Picture Quality engine adjusts color temperature and contrast scene-by-scene, and the AI Crosshair overlay helps in competitive games. PIP and PBP split-screen modes let you display two sources simultaneously, which is great for monitoring chat while gaming.

Setup is genuinely plug-and-play. I connected my PS5, enabled 4K output, and was gaming within minutes. The monitor automatically recognized the console and applied optimal settings. The 131% sRGB color gamut is wide enough for vivid gaming visuals, though it’s not color-accurate enough for professional creative work.

VA Panel Advantages and Trade-offs

The 3000:1 contrast ratio is the real differentiator here. Dark scenes in horror games and space exploration titles look dramatically better than on 1000:1 IPS panels. The trade-off is viewing angles: VA panels shift colors more at off-angles. If you sit centered in front of the monitor, this isn’t an issue. The 1500R curve also helps maintain consistent viewing angles across the 32-inch span.

Console Gaming Experience

PS5 and Xbox Series X both output 4K 120Hz with VRR enabled. The HDMI 2.1 VRR implementation eliminates screen tearing without the input lag penalty of traditional V-Sync. Some users note that VRR mode slightly mutes colors compared to fixed refresh, but I found the difference minimal during gameplay.

8. CUNPU S027 – Best for Color-Critical Work

The CUNPU S027 targets a different audience: creators who game. With 99% DCI-P3 coverage and Delta E under 2 factory calibration, this monitor delivers color accuracy that rivals professional displays costing twice as much. I used it for photo editing in Lightroom and the colors matched my calibrated reference display closely.

At 27 inches, the 163 PPI pixel density makes text look almost print-like. Code editors, spreadsheets, and detailed documents are incredibly sharp. The full-bandwidth HDMI 2.1 and DisplayPort 1.4 connections at 48Gbps ensure no compression artifacts, and the 160Hz refresh rate at 4K makes gaming smooth after you finish work.

The matte anti-glare finish is well-implemented, reducing reflections without making the image grainy. The full ergonomic stand with height, pivot, swivel, and tilt adjustment allows comfortable positioning for long work sessions. The monitor is VESA mount compatible if you prefer a monitor arm setup.

Creative Workflow Integration

The 99% DCI-P3 and Delta E under 2 specs make this viable for photo editing, video color grading, and design work. It won’t replace a true professional reference monitor with hardware calibration, but for creators who also want a capable gaming display, the S027 delivers both at a fraction of the cost. Pair it with our best 4K monitors for coding guide for more creator-focused options.

Gaming After Hours

Switching from work to gaming mode takes seconds. The 160Hz refresh rate and 1ms response time handle fast-paced games well, though the 1000:1 contrast ratio means dark scenes won’t look as deep as on VA or OLED panels. For a dual-purpose monitor that handles color-critical work by day and gaming by night, the S027 is a strong choice.

9. ZZA Z27E – Best Budget 4K Monitor with HDMI 2.1

The ZZA Z27E is the most affordable 4K monitor with HDMI 2.1 on this list, and it punches well above its weight. With a 144Hz refresh rate, 4000:1 contrast ratio, and 100% sRGB coverage, it delivers a surprisingly complete gaming experience. Multiple reviewers on Amazon have compared the picture quality favorably to monitors from Samsung and LG that cost significantly more.

The dynamic lighting on the back panel adds a nice aesthetic touch, with running horse and breathing effects that sync with your setup’s RGB ecosystem. The eye-care technology reduces blue light and flicker for comfortable extended use. At just 5.4 kg, it’s one of the lightest 27-inch 4K monitors available, making it easy to mount or reposition.

The 4000:1 contrast ratio is unusual at this tier and gives dark scenes more depth than typical budget IPS monitors. HDMI 2.1 and DisplayPort 1.4 are both included, supporting 4K at up to 144Hz. The monitor is also VESA wall-mount compatible, which is useful for clean desk setups.

What You Give Up at This Price

The stand only offers tilt adjustment, so you’ll want a monitor arm for height and pivot. There are no built-in speakers, and the brand lacks the established reputation of LG or ASUS. Some users report port reliability issues after months of heavy use. The 1-year warranty is standard for budget monitors but shorter than premium alternatives.

Gaming and Console Compatibility

PS5 outputs 4K 120Hz without issues on the Z27E. Xbox Series X works equally well. The 144Hz ceiling is above what consoles can utilize but provides headroom for PC gaming. If you’re building a budget gaming setup, pairing this monitor with a mid-range GPU gives you an excellent 4K experience without breaking the bank.

10. ASUS TUF Gaming VG27UQ1A – Best for Competitive Gaming

The ASUS TUF Gaming VG27UQ1A is built for competitive gamers who want 4K resolution with serious motion clarity. The ELMB Sync (Extreme Low Motion Blur Sync) technology is the key differentiator: it works alongside VRR to eliminate both tearing and motion blur simultaneously. In fast-paced shooters, this makes a noticeable difference in tracking moving targets.

The 160Hz refresh rate at 4K with a 1ms response time handles competitive gaming well. Variable Overdrive technology adjusts the pixel overdrive based on your current frame rate, preventing overshoot at lower framerates. The 95% DCI-P3 color gamut and HDR support produce vibrant visuals, though HDR performance is modest compared to OLED monitors.

ASUS bundles all necessary cables and tools in the box, including an HDMI cable and DisplayPort cable. The DisplayWidget software allows OSD adjustments from your desktop, which is more convenient than fiddling with physical buttons. The 3-year warranty provides peace of mind, especially for a monitor at this price point.

ELMB Sync Explained

Traditional motion blur reduction technologies disable VRR, which introduces tearing. ELMB Sync solves this by running both technologies simultaneously. The result is clean motion with no tearing and minimal blur. For competitive FPS games where every frame of clarity matters, this technology provides a genuine advantage. If you want to learn more about high-refresh options, check our best 4K monitors with high refresh rate guide.

Stand and Ergonomics

The VG27UQ1A’s biggest limitation is the lack of height adjustment. The included stand only offers tilt, so you’ll need a monitor arm or a riser to get the screen at eye level. The single HDMI port means you can only connect one HDMI source directly; a switcher is needed for multi-console setups. These compromises are understandable at this tier, but worth knowing before you buy.

How to Choose the Best 4K Monitor with HDMI 2.1

Panel Types: IPS vs VA vs OLED

IPS panels offer wide viewing angles and good color accuracy at a moderate price. VA panels deliver superior contrast ratios (3000:1 or higher) for deeper blacks but narrower viewing angles. OLED and QD-OLED panels produce perfect blacks with infinite contrast, the fastest response times, and the widest color gamuts, but cost more and carry burn-in considerations.

For competitive gaming where response time matters most, OLED’s 0.03ms response is unbeatable. For budget-conscious buyers who want a good all-rounder, IPS is the safest choice. For immersive single-player gaming in darker rooms, VA panels punch above their weight with that contrast advantage.

Refresh Rate: 120Hz vs 144Hz vs 165Hz vs 240Hz

PS5 and Xbox Series X max out at 120Hz, so anything above that only benefits PC gamers. If you primarily game on consoles, a 120Hz or 144Hz monitor is sufficient and saves money. PC gamers with high-end GPUs should consider 165Hz or 240Hz models to take advantage of every frame their hardware can produce.

Size: 27-Inch vs 32-Inch

At 4K resolution, a 27-inch display delivers around 163 PPI for extremely sharp text and images. A 32-inch display drops to about 138 PPI, which is still sharp but noticeably less dense. The larger screen provides more immersive gaming and more usable desktop space. For desk setups where you sit 2-3 feet away, 32 inches feels cinematic. For tighter desks or mixed productivity use, 27 inches is more practical.

HDMI 2.1 vs DisplayPort 1.4

HDMI 2.1 supports 48Gbps of bandwidth, enabling 4K at 120Hz natively and higher refresh rates with DSC (Display Stream Compression). DisplayPort 1.4 also supports 4K at high refresh rates but requires DSC for anything above 120Hz at 4K. Console gamers must use HDMI 2.1 since PS5 and Xbox Series X lack DisplayPort outputs. PC gamers can use either, though HDMI 2.1 provides more bandwidth headroom. If DisplayPort 2.1 is important to you, see our best 4K monitors with DisplayPort 2.1 guide.

HDR Certification Levels

HDR400 is the entry level, offering a modest brightness boost over SDR. DisplayHDR 600 provides noticeable improvement with local dimming. DisplayHDR 1000 delivers a genuinely impactful HDR experience with high peak brightness. DisplayHDR True Black 400, found on OLED monitors, produces the best HDR experience for dark content because of the perfect black levels. For real HDR impact, look for DisplayHDR 600 or higher, or any OLED with True Black certification.
