#1 Pick ASUS PG278QR 27″

Award: Best 4K Gaming Monitor

Price: $519.99Features: AMD FreeSync, 1ms response time, ASUS GamePlus configuration profiles

WHY IT’S A TOP PICK: The ASUS PG278QR is a cheaper 4K monitor for budget gamers.

It’s rare to find a product that really encompasses everything you expect when you hear the phrase “the complete package”, but the ASUS PG278QR is about as close as they come without going overboard. While this monitor’s perfect for the hardcore gamer, pair it with the best monitor for video editing for the best of both worlds.

At only $519.99 it’s simultaneously one of the cheapest, yet feature-rich gaming displays on the market (4K or otherwise), and is a marvelous example of how a company can make a solid product with great performance but still keep it within the range of most gamer’s budgets. All the standards are here, including the defining 3840 x 2160 resolution (high pixel density) for superb picture quality, 1ms response time and up to 165Hz refresh rate for ultra-quick games, 16:9 aspect ratio, and AMD’s FreeSync technology which prevents screen tearing during high-paced action sequences on screen. And speaking of fast action, the best gaming mouse will make sure that you don’t miss a beat whether shooting, running, or jumping. That aspect ratio of 16:9 makes watching movies great too. Also, the HDMI 1.4, DisplayPort 1.2, and USB 3.0 ports make for flexible connectivity options, although sadly no USB C port. This display has great viewing angles of 170°(H)/160°(V) with good brightness, making it such a beauty to look at.

For these reasons and so many more, the ASUS PG278QR is the best overall gaming monitor with 4K for 2019. It is one of the best gaming monitors there is.

#2 Pick Acer Predator XB271HK 27″ Gaming Monitor

Acer HB271HK
Got a job that demands 100% color accuracy but like to frag on the side? The XB271HK is the pick for you

Award: Best High Performance 4K Gaming Monitor

Price: $869.00 | Read Full Review: Acer Predator XB271HK ReviewFeatures: Nvidia G-Sync compatibility, 1ms GTG response time, 5 USB 3.0 ports

WHY IT’S A TOP PICK: The Acer Predator XB271HK is perfect for gaming or creative work, take your pick!

It’s no secret by now that when it comes to gaming monitors, Acer and its Predator line of performance-focused displays have quickly rocketed to the top of every self-respecting gamer’s Christmas wish list. This is the best gaming monitor from Acer. Right up there with the ASUS Rog Swift. It offers a response time of 4ms, a refresh rate of 60Hz, and a 16:9 aspect ratio, as well as flicker less technology that reduces screen flickering. It also features Nvidia G-Sync technology to prevent screen tearing, providing gamers with the ultimate gaming experience. Plus, the Ergostand on this display allows the monitor to tilt and move up or down to find the best viewing angle, while the monitor itself has a wide 178° both horizontal and vertical viewing angles.

We raved about the Predator X34 when we got a chance to review it in house, and everything that made that screen great is back in spades with the slightly more conservative – but still obscenely powerful – Predator XB271HK. And while all the options you’d hope for make an appearance in the XB271HK just as they did in the X34, what sets this screen apart is its 100% accurate color reproduction across sRGB and AdobeRGB color gamut scores that makes for a perfect picture quality.  If the gamer in your life already has a monitor, check out this list for some more of the best gifts for gamers.

This means if you need a display that can perform just as sufficiently at work as it does at home, this is going to be the best buy for you. Especially if you want the best external monitor for gaming.

#3 Pick LG 27MP59G-P 27″ Gaming Monitor

The LG 27MP59G-P may not look as flashy as other gaming products, but it’s got just as much polish and precision in every one of its parts.

Award: Best Budget 4K Gaming Monitor

Price: $229.99 | Read Full Review: LG 27MP59G-P Features: AMD FreeSync, 1ms response time, IPS display

WHY IT’S A TOP PICK: The LG 27MP59G-P is fast, powerful, and cheap. What more could you ask for?

Rounding out our list is the 27″ LG 27MP59G-P 4K UHD gaming monitor, which, while not as flashy or stylish as some other LG or overall gaming products on the market, still performs handily under the pressures of what gamers need in a pinch (while they’re pinching pennies). It is an IPS panel type.

The 27MP59G-P doesn’t have spectacular color representation, so if you’re looking for something that’s good for creative work and gaming both we’d refer you to the XB21HK instead (100% color accuracy), but outside of that small caveat everything else you could want is here to shine. AMD FreeSync compatibility, 75 Hz refresh rate, Dynamic Action Blur Sync, black stabilizer technology, and a cool $229 price tag are just a few of the features that come stock with this LG 4K monitor, all of which helped it to earn the number three spot on our list this year. If you’re looking for budget IPS monitors or an affordable FreeSync monitor, this is the choice for you. We love that this best cheap monitor has these features. Pair it with the best monitor stand for added versatility.

Note: Other 4K gaming monitors worth mentioning that are not on our list include the Asus ROG Swift PG279Q 27-inch screen and the Alienware 55 OLED Gaming Monitor. The Asus ROG Swift 27-inch 1440p resolution comes with Nvidia G Sync technology, 165Hz refresh rate, and Eye Care technology for low blue light mode. The Alienware monitor offers a refresh rate of 120Hz and a low input lag, and achieves “true black” for higher contrast ratio and gaming detail. Lastly, the Samsung CRG5 budget gaming monitor with 144 Hz, 1080p resolution, and G Sync compatibility which eliminates image tears and provides excellent image quality.

Mistakes to Avoid

First and foremost, don’t buy just any 4K monitor that’s on the cheap end of the scale and think you can automatically use it for gaming due to the resolution alone. Gaming monitors in particular are built with certain features and fast response times that coincide with what gamers need most: speed, and responsiveness.

Also, make sure you avoid displays that don’t come with custom gaming profiles. These are settings you can pre-configure depending on the game you’re playing to ensure you get the best possible brightness, contrast ratio, and speed for when you play games of different styles such as FPS, RTS, and MMMORPGs.

Most Important Features on a 4K Gaming Monitor

Screen Size

  • The best 4K gaming monitor will be larger than at least 24″, as the detail beyond that isn’t worth the extra resolution if you don’t have the screen space to truly enjoy it.
  • 27- to 34-inches screen size is the sweet spot for most gaming monitors, and this goes doubly so for 4K options. There are other ultrawide monitors for gaming such as the 49-inch Samsung CHG90 but they’re much more expensive.
  • Not so big that it won’t fit on your desk, but also large enough that the 4K resolution has an opportunity to stretch its legs out and shine. A 21:9 aspect ratio isn’t needed.

Ports and Connectors

  • Make sure that both your gaming monitor and the machine you plan to play with have a DisplayPort-HDMI adapter, version 1.2. Gaming monitors also usually include USB 3.0 or USB C ports.
  • This is important for G-Sync and FreeSync technology, both of which make sub 2ms response times possible.

G-Sync/FreeSync

  • Both G-Sync and FreeSync, also known as adaptive sync technology, are relatively new technologies in the gaming space, and have only recently made their way onto 4K displays as of this year.
  • Each prevent a phenomena known as “screen tearing”, where the information the graphics card is sending to the monitor is temporarily out of sync (hence the names).
  • These create a solid link between both devices so they never miscommunicate, and the animations on-screen stay smooth and buttery throughout.

Price

  • In general, there’s no rule for how much a 4K gaming monitor may set you back.
  • Some like the Samsung UE590 or ASUS MG28UQ don’t break the $500 mark, but they are also made for gaming exclusively.
  • Others, like the Acer XB271HK, creep into the $900 range, primarily due to the fact that it’s both a gaming monitor and a creative professionals monitor, complete with 100% color gamut representation.

Refresh Rate

  • Unfortunately, for the time being there are no 4K gaming monitors that can press past the 60Hz refresh rate limit…though this is looking to change in very near future.
  • Due to the strains that a high refresh/high pixel count combo can put on your average graphics card (and more to the point, DisplayPort 1.2), right now only a GTX 1080 SLI combo would come within a mile of being able to support a 4K display that ran at 100Hz, let alone the refresh rate 144hz or the rumored 240Hz that should be coming out in the next year or so.
  • Regardless, as long as your 60 Hz monitor has G-Sync, you should still get decent performance and picture quality that will last over the long haul.

Which Best 4K Gaming Monitor is Right for You

The best 4K gaming monitors have come a long way in recent years. Once populated by a few fringe hyper-expensive models that only had one or two of the features that gamers wanted, now almost all of them have a bevy of port options, G-Sync or FreeSync compatibility, and one model in particular is even great for creative work to boot.

Which is right for you will ultimately depend on your budget, and more to the point, what kind of graphics card you have. In the end, you’ll want a screen that has G-Sync if you run an Nvidia GPU with Nvidia GeForce card, while a monitor with Free-Sync is going to be the choice for the AMD loyal. Luckily we have a mix of both on our list of the best 4K gaming monitors in 2019, so you always have plenty of options when you choose the one that finally lands on your desk at home!

4K Gaming Monitor FAQs

Are 4K gaming monitors worth it?

4K gaming monitors can really take your gaming experience to the next level, but only if you have a GPU powerful enough to handle 4K resolution. So, if you’re ready to spend a little more to ensure you have a 4K-capable GPU and all the supporting accessories (DisplayPort cables, etc.), then 4K monitors are definitely worth it.

What is the best refresh rate for a 4K monitor?

144Hz 4K monitors have finally hit the market, which was so used to 60Hz 4K monitors for so long. If you’ve got a high-performance GPU, you can overclock it to give you a full 144Hz on your 4K monitor. Be aware that 4K gaming monitors with this high of a refresh rate will be a bit more expensive than 60Hz monitors and require the use of at least a DisplayPort 1.4 display cable.

Is there a 144Hz monitor?

Yes, there are several 144Hz 4K monitors available today. Some of the most popular options include:

  • Acer Nitro XV273L
  • Acer Predator XB273L
  • Asus ROG Swift PG27U

Which is the best 4K monitor?

The best 4K monitor by far is the Asus PG278QR. With a whopping 27 inches of 4K real estate, FreeSync capabilities and blazing fast response time, this monitor can elevate your gaming experience in more ways than one. It’s also one of the most affordable 4K monitors available today, making it a great choice for gamers on any kind of budget.

  1. The Samsung UE590 does NOT have an IPS display – it’s TN. And stating a panel’s response time is utterly meaningless. TN panels have a 1 ms. response time, and most IPS panels are around 4 ms. Stating that response time is meaningless. What matters is the response time of the entire chain, including the panel, which will always be much greater than the panel’s response time.
