Best 4K Gaming Monitors for PC 2019: 144 Hz to Budget

With great pixels comes great image quality. So it's no surprise that gamers are obsessing over monitors with 4K resolution (also known as UHD) these days. It's the highest resolution you can get in a good gaming display. A panel packing 8.3 million pixels (3840 x 2160) makes your PC games look incredibly smooth and realistic images. That stacked pixel army also makes it possible to stretch your screen size well past 30 inches without seeing pesky individual pixels.

But if you've ever shopped for a 4K monitor, you know they aren’t cheap (yet). And while 4K's all about that premium resolution, you still want solid specs for gaming, like a 60 Hz or greater refresh rate, low response time and your choice of adaptive sync (Nvidia G-Sync or AMD FreeSync, depending on your PC's graphics card). 

With all that considered, if 4K isn’t for you yet, take a look at our Best Gaming Monitors page for our favorite monitors that are great but have lower resolutions. 

If you’re ready to invest in high-res gaming, check out our handpicked list of the best 4K gaming monitors, carefully selected based on independent and rigorous testing.

Quick Shopping Tips

When buying a 4K gaming monitor, consider the following:

  • 4K gaming requires a high-end graphics card. If you don’t have an Nvidia SLI or AMD Crossfire multi-graphics card setup, you’ll want at least a GTX 1070 Ti or RX Vega 64 for games at medium settings or an RTX-series card or Radeon VII for high or greater settings.
  • 4K monitors are even more expensive if you want 144 Hz. Those looking to save money should consider getting a monitor with a lower refresh rate, as low as 60 Hz. Just make sure it has G-Sync or FreeSync.
  • G-Sync or FreeSync? A monitor’s G-Sync feature will only work with PCs using an Nvidia graphics card. FreeSync will only work with PCs running an AMD card. At 4K, FreeSync maxes out at 120 Hz, but G-Sync can go up to 144 Hz. For an in-depth comparison between the two’s performance, see our Nvidia G-Sync vs. AMD FreeSync comparison article.
  • 4K and HDR go hand-in-hand. 4K displays will often support HDR (high dynamic range) content for extra bright and colorful experiences. Often, however, you can't run it alongside G-Sync or FreeSync. For more on HDR, see our article on HDR and what it means for your monitor.

Asus ROG Swift PG27UQAsus ROG Swift PG27UQ

1. Asus ROG Swift PG27UQ

Best 4K / 144 Hz Gaming Monitor

Rating: 4.5/5 (Editor's Choice)

Screen Size & Aspect Ratio: 27 inches, 16:9 | Resolution: 4K @ 120 Hz | Panel Type: IPS | Refresh Rate: 144 Hz with overclock | Response Time (GTG): 4ms

Pros: G-Sync • Stunning image • Amazing SDR and HDR contrast • Over 90 percent DCI-P3 coverage • Build quality, styling

Cons: Expensive

The Asus ROG Swift PG27UQ is the best 4K gaming monitor for most people. Whenever a 4K display can manage a refresh rate that's greater than 60 Hz, it’s a big win. The PG27UQ surpasses that significantly with 144 Hz when overclocked. But what really makes this display--and its image quality--a winner is its full-array WLED backlight with zone dimming. With that, you can expect unbeatable HDR. Finally, with a response time that's 1ms faster than its bigger competitor, the Acer Predator X27 (listed below), the PG27UQ scores the 4K gaming display crown.

2. BenQ EL2870U

Best Budget 4K Gaming Monitor

Rating: 3.5/5

Screen Size & Aspect Ratio: 28 inches, 16:9 | Resolution: 4K | Panel Type: TN | Refresh Rate: 60 Hz | Response Time (GTG): 1ms

Pros: FreeSync • Value • HDR compatibility • 24p cadence support • Build quality • Out-of-box accuracy

Cons: Low native contrast • 60 Hz limit

Budget and 4K aren't two phrases you typically see together. The BenQ EL2870U won't satisfy hardcore gamers, but it's the best way for causal gamers to get an acceptable 4K gaming experience for less than $500 (it was $348 / £260 at the time of writing). These gamers can make do with the 60 Hz refresh rate paired with a low 1ms response time, plus FreeSync. But if you’re a hardcore gamer looking for an improvement over a QHD resolution, 144 Hz monitor, make the Acer Nitro XV273K ($780 / £900 at the time of writing) your budget pick instead.

3. Philips 436M6 Momentum

Best FreeSync 4K Gaming Monitor

Rating: 4.5/5 (Editor's Choice)

Screen Size & Aspect Ratio: 42.5 inches, 16:9 | Resolution: 4K | Panel Type: VA | Refresh Rate: 60 Hz | Response Time (GTG): 4ms

Pros: FreeSync • Bright • Excellent HDR • Wide color gamut • Accurate without calibration • Build quality • Comes with a handy remote

Cons: Limited calibration options • Middling input lag • Few stand adjustments

When we played our favorite games on the Philips 436M6, FreeSync ensured tear-free frames, while sRGB games popped, thanks to the display's added gamut color. HDR games also played without any screen tearing. The large, 43-inch display was even more appetizing to the eyes with a high 4,000:1 contrast ratio. On top of that great image, the 436M6's TV-like size made games like first-person shooters all the more intense.

Screen Size & Aspect Ratio: 27 inches, 16:9 | Resolution: 4K @ 120 Hz | Panel Type: IPS | Refresh Rate: 144 Hz with overclock | Response Time (GTG): 5ms

Pros: G-Sync • Excellent HDR • Extended color • Stellar gaming experience • Build quality

Like the Asus ROG Swift PG27UQ listed above, the Acer Predator X27 has a full-array backlight with zone dimming, so you can expect mouth-watering HDR delivery. With insane gaming specs, the monitor delivers tear-free gaming, even at high framerates. The Predator X27 also has a slight edge over the PG27UQ in terms of out-of-box color accuracy. And the included light hood is a welcome addition.

5. HP Omen X 65 Emperium

Best 4K Gaming Monitor Splurge

Rating: 4.5/5 (Editor's Choice)

Screen Size & Aspect Ratio: 64.5 inches, 16:9 | Resolution: 4K | Panel Type: VA | Refresh Rate: 144 Hz | Response Time (GTG): 4ms

Pros: G-Sync • Pro-level color accuracy • Excellent SDR and HDR contrast • Built-in soundbar delivers excellent audio quality • Sturdy build

Cons: Very expensive

The HP Omen X 65 Emperium is a 65-inch juggernaut that guarantees larger-than-life gaming. In our benchmarking, it showed performance worthy of its premium price tag with zero gaming hiccups and high framerates at high settings. The included soundbar is a powerful addition and amplifies the immersive and high-end experience. If that weren't not enough to earn the high cost, the monitor comes with Nvidia Shield, which has gaming, TV and movie streaming options built right in.
