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

With great pixels comes great image quality, and that’s why monitors with 4K resolution (also known as UHD) are attracting so many gamers right now. A panel packing 8.3 million pixels (3840x2160) gives users the smoothest and most realistic images for PC gaming. That pixel army also makes it possible to stretch your screen size well past 30 inches without seeing those pesky individual pixels.

However, anyone who’s shopped for 4K monitors knows these displays aren’t cheap (yet). Plus, you’re still going to want solid gaming specs, like a 60 Hz-plus 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, take a look at our Best Gaming Monitors page for lower resolution recommendations. 

But if you’re ready to invest in 4K gaming, check out our curated list of the best 4K gaming monitors, handpicked based on our rigorous testing.

Quick Shopping Tips

When buying a gaming monitor for your rig, 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.
  • It’s even more expensive if you want 144 Hz. If you’re looking to save money, consider getting a monitor with a lower refresh rate, as small as 60 Hz, as long as it comes with FreeSync (for AMD graphics cards) or G-Sync (for Nvidia graphics cards).
  • G-Sync or FreeSync? A monitor’s G-Sync function will only work with PCs using an Nvidia graphics card. FreeSync will only work with PCs running an AMD card. At 4K resolution, 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 article.
  • 4K and HDR go hand-in-hand. 4K displays will often support HDR content for extra bright and colorful experiences. 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

We pick the Asus ROG Swift PG27UQ as the best 4K gaming monitor. Anytime a 4K display has a refresh rate better than 60 Hz, it’s a big win. The Asus ROG Swift PG27UQ surpasses that significantly with a 144 Hz refresh rate when overclocked. But what really makes this monitor--and its image quality--stand out is its full-array WLED backlight with zone dimming, which promises unbeatable HDR. This display has a response time that's 1ms faster than that of the Acer Predator X27, its biggest competitor (listed below), allowing the PG27UQ to take the 4K gaming 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 terms that usually go together. The BenQ EL2870U, while not explicitly made for gaming, is currently the best way to get an acceptable 4K gaming experience for less than $500 (£380). Casual gamers can make do with the 60 Hz refresh rate combined with the monitor's low response time and FreeSync. But if you’re a hardcore gamer and want an upgrade from a QHD, 144 Hz monitor, make the Acer Nitro XV273K (MSRP of $900 / £900) your budget choice 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 this 43-inch monitor, FreeSync ensured tear-free gaming, while sRGB games popped with added gamut color. HDR games also ran without tearing, and the very high 4,000:1 contrast ratio served a feast for the eyes. Additionally, we loved how this monitor's TV-like size made games like first-person shooters more dramatic.

4. Acer Predator X27

Best G-Sync 4K 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): 5ms

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

Cons: No brightness adjustment in HDR mode • Expensive

Like the Asus ROG Swift PG27UQ above, the Acer Predator X27 has a full-array backlight with zone dimming, so you can expect mouth-watering HDR content. Its insane gaming specs promise tear-free gaming, even at high frame rates. The monitor also has a slight edge over the PG27UQ in terms of out-of-box color accuracy. The included light hood is a nice addition too.
