4k & 144Hz together in one monitor? Between these and the new 1440p 240hz choices, the next generation of displays is mouth-watering.

Which is why today’s feature will take you through the best 144hz UHD monitors for gaming and more, with several different budgets in mind.

Top Picks

Best of the Rest: Quick-Fire Picks

Overall Best 4k 144Hz Monitor: LG 27GN950-B 27 Inch UHD

Standing confidently as our overall best pick, this 4k high refresh rate monitor stands tall amongst the market options, with a fantastic sweet spot between specs and value.

Perhaps the most impressive part of our top choice is how LG has managed to make this an IPS panel with a 1ms response time. Usually, the tradeoff for IPS (which typically gives better picture quality over equivalent VA/TN panels) is higher latency. Having both low response time and IPS is usually reserved for the premium models, but the 27GN is one of the cheap 4K 144Hz display options on the list!

The specs also boast a DCI-P3 98% color gamut (an impressive offering for the price-point with all the other features) and VESA DisplayHDR 600. Between these two factors and the IPS panel, the picture quality on this LG gaming monitor is mind-blowing and will be enjoyable even if you’re running games at less than 144 FPS (you can expect movies and general use to look great on here too).

With full G-Sync / AMD Free Sync compatibility you can still enjoy the extra smoothness these software add-ons offer even on such a high res 144HZ monitor.

The design and build quality of this monitor is excellent too. Adjusting the unit feels sturdy and secure, with VESA screws for wall mounting if desired.

Our favorite elements of the build, however, are the thin bezels and RGB sphere lighting 2.0 on the back. This lighting means that colors are outputted on the wall behind your monitor and are designed to blend into the sound and/or visuals on your screen. This sounds gimmicky but tied in with the fantastic screen-to-body ratio, the extra light feels immersive, and the tiny bezels mean this pick works fantastically in a dual monitor setup.

This isn’t just the best 27-inch 4k 144Hz monitor, but in our opinion, the best overall choice for people in the market today (the fact that this is on the cheaper end of the choices is a complete marvel),

Best Cheap 4K 144Hz Monitor: VIOTEK GFI27QXA 27-Inch

Although we think the LG pick offers fantastic value, we appreciate that such high-end monitor options may not be flattering to many reader budgets.

Luckily, the cheapest 4K 144HZ gaming monitor going is still a great offering that doesn’t feel like you’re “cheaping out” on a budget pick.

Boasting an IPS panel, a 122% sRGB color gamut, 1M:1 DCR, this display is still going to provide fantastic colors, whites, and blacks you’ll want while gaming or watching media (the picture won’t look quite as good as the LG pick, but it will still be fantastic when you consider the dramatic price reduction).

The build quality is great here too. With a sturdy stand, fairly thin bezels, and plenty of movement options, this is another area that doesn’t feel compromised on in the lesser price.

So with all that said, you may be wondering why we didn’t give this the overall top quick. Well, there’s a couple of things to point out:

  • The response time is a tad misleading. It is listed officially as 1ms, but documentation with the monitor talks of a 3ms latency. This is likely due to 1ms being the refresh rate under “optimum conditions” but we would recommend assuming that you’ll be playing with 3ms (still very low for a budget IPS display).
  • You may have noticed that this is officially a 120Hz 4k monitor overclocked to 144Hz. For the most part, this is an ideal option as it saves price, but a minority of users report some problems with very slightly visual stuttering on 144Hz where they have to turn back to 120Hz to remove. But for most gamers, this works fine, and there is a 3-year U.S company warranty if any concerns arise.

We should state that neither of these should be dealbreakers and this VIOTEK offering still manages low latency, great colors/blacks, and a superb build quality alongside its high refresh rate and 3840×2160 resolution.

This choice is easily the best budget 4k 144Hz monitor available today.

Best Large 4K 144Hz Monitor: ASUS ROG Swift PG43UQ 43”

Now, for those after a larger gaming experience, this ASUS 144HZ 4K monitor comes in at a whopping 43-inches. Perfect for someone who wants to use a gaming monitor as a TV or for a massive main monitor (I’ve previously had a similar setup where you effectively use one screen as a “dual display” when not gaming, it can work really well.

This ROG Swift model comes with a fantastic HDR1000 rating and 90% DCI-P3 color gamut. Both specs are great, but the HDR 1000, in particular, is awesome.  You can expect this to have some of the best whites and blacks of any high end LED gaming monitor.

Another Freesync / G-sync 4k display, this ASUS screen also features GameFast Input Technology that results in an effective 1ms response time (we really appreciate how they haven’t compromised on latency when many larger monitor offerings do).

This display is beautiful and well built, with its 4K 144Hz functionality being fully enabled with a GPU by only 1 DisplayPort 1.4 input. The bezels are a tad larger than most of the other picks. But at this size? It’s not really a surprise, and they’re still thin compared to many other monitor choices.

ASUS has really nicely filled that large monitor gap in this market by creating the PG43UQ. If you’re looking for a huge 4K 144Hz monitor, this is definitely your best option.

Runner-Up Best 4K 144Hz Monitor: Asus ROG Swift PG27UQ 27″

We wanted to highlight another great all-rounder pick, as we appreciate that 144Hz UHD monitors are sometimes low in stock and our LG choice may not be available when you’re looking to buy.

ASUS has a monitor in the 27-inch range that is, in some ways, even more compelling than the LG 4k 144Hz display.

Another IPS panel, this ASUS SWIFT screen has a wonderful HDR1000 rating and 97% DCI P3 color gamut. With these specs (especially the impressive high dynamic range), you can expect fantastic whites, blacks, and colors that even slightly surpass the top LG monitor.

The PG27UQ is also one of the nicest builds on the list. With an incredibly sturdy durable design, ASUS answers LG’s backlighting options with its own take: an ARGB ASUS logo on the back (and a customizable logo shining from the bottom of the display). We always rate ASUS’s addressable RGB lighting as it tends to go nicely with their Aura Sync software to give a user a unique look, so you can expect this monitor to look great in the dark.

The reason we would pick the LG monitor over this one is that the ASUS ROG Swift, unfortunately, runs at 4ms as opposed to 1ms. Now, if you’re not buying a monitor for gaming, this won’t be a problem. But we expect many readers looking at a UHD high refresh rate monitor will be after something with as low latency as possible for inputs.

If low latency isn’t a high priority for you then this ASUS monitor does offer a better picture, the only other con we’d point out on this choice is a minority of users complaining about loud fan noise. Most seem to be fine with this, but if achieving an ultra-quiet setup is your plan, bear this in mind.

With one of the nicest builds and picture qualities on the list, the PG27UQ is our top 4k 144HZ monitor pick for the average user if our LG option isn’t available.

Alternative Picks – Best of the Rest

While the top 4 picks are what we’d primarily steer you towards when looking for the best 4K 144Hz monitors for gaming or media, there are some other great options and similar alternatives (e.g. 120Hz 4K monitors). We’ve displayed the best below for those with more unique requirements.

Best OLED 4K Gaming Monitor: Alienware AW5520QF

Quite possibly the best gaming monitor on the market today. This Alienware display will have, by far, the best picture quality on the list with its OLED screen. The fact that it runs at 120Hz alongside that is simply wonderful.

So why don’t we rate it for most users? We think you’ll see why after looking at the price! But by all means, if you have the budget for the most powerful setup possible, this is perfect for you.

Second Best Budget 4K 144Hz Monitor: Acer Predator XB3-27″

If you are after a cheap 4k 144Hz gaming monitor but wanted something from a more reputable monitor manufacturer, then this refurbished Acer model is perfect for you. 

Best WQHD 120Hz Monitor: Alienware AW3420DW

While not 4K or 144Hz, WQHD is very impressive and significantly higher-res than traditional 1440p. We think someone in the market for a premium screen for gaming will really appreciate the level of immersion an ultrawide high refresh rate monitor can offer.

Worth Mentioning: Nixeus NX-EDG274K

Another 144Hz 4K monitor option in the mid-range price, this Nixeus offering is decent, but we don’t rank it as much as our top LG pick (which is in the same price range) due to its slower response time (4ms) and coming from a less known monitor brand. That said, if you catch it on a good sale, this would make a great budget 4K 144HZ gaming monitor pick.
