In the past few years, as 4k TVs have improved, HDR support has become the norm. On the other hand, the situation is quite different for monitors, and HDR is still relatively new. Few monitors support it, and even fewer monitors support it properly and can display HDR content the way it's meant to be seen. If you're looking for a new monitor, though, and HDR is important to you, then there are still a few choices out there. Although the majority of them have low native contrast and can't get as bright as TVs, they still offer a different experience from monitors that only support SDR.
We've tested more than 10 4k HDR monitors, and below you'll find our recommendations for the best ones available for purchase. Make sure to check out our recommendations for the best 4k monitors, the best 4k gaming monitors, and the best HDR TVs.
The best HDR monitor that we've tested is the Acer Predator X27. It's a well-built model that's designed for gaming but offers great picture quality in HDR. It also has a USB hub with four USB ports, and one of them on the side supports quick-charging so that you can charge your devices through it.
It has good coverage of the DCI P3 color space used in most content and has even better coverage of the wider Rec. 2020 color space. It's the brightest monitor in HDR that we've tested, enough to truly bring out highlights, similar to some TVs. If you also want to use it for media creation, it has near-perfect coverage of the Adobe RGB color space used in photo editing, and it has incredible gradient handling. As advertised, the Acer offers great gaming performance as it has a 144Hz refresh rate, native G-SYNC support, and a quick response time that it's even quicker at 60Hz.
Unfortunately, it has disappointing out-of-the-box color accuracy, so you may need to get it calibrated to enjoy it to the fullest. Its IPS panel has a low contrast ratio, so blacks appear closer to gray when viewed in the dark. On the upside, that means it has wide viewing angles, ideal for sharing your screen with others. All in all, this is one of the best 4k HDR monitors that we've tested.
If you want a monitor with a bigger screen for better immersion, then you're better off with a TV, like the LG 48 CX OLED. Its 48 inch OLED panel can produce perfect blacks for a fantastic dark room viewing experience, and since it doesn't have a backlight, there aren't any issues with blooming in dark scenes. It has wider viewing angles and better reflection handling, but it might be hard to place the screen at your optimal viewing position because it doesn't allow for any ergonomic adjustments. Its response time is near-instantaneous, and it has a Black Frame Insertion feature that can further improve motion clarity. It supports FreeSync and is certified as G-SYNC compatible.
Overall, the Acer is a better choice because it has a better HDR color gamut, higher peak brightness, and better ergonomics. However, if you want a big screen for the best game immersion, then go with the LG.
The ASUS ROG Strix XG27UQ is the best 4k HDR monitor for gaming we've tested. It's an excellent gaming model that delivers a smooth and responsive gaming experience thanks to its low input lag, quick response time, and 144Hz refresh rate. It has an IPS panel with decent viewing angles, and it provides good visibility in bright lighting conditions. The build quality is great, and the stand allows for a good amount of ergonomic adjustments.
It has a good HDR color gamut with excellent coverage of the commonly-used DCI P3 color space. It can produce a wide range of colors; however, it doesn't display dark shades well due to its IPS panel's mediocre contrast ratio. It has decent HDR peak brightness, but bright highlights are only noticeable if you're in a dark room. Unfortunately, even though it has a local dimming feature, it's edge-lit and performs terribly.
The many additional features can enhance your gaming experience. Shadow Boost make objects more visible in dark scenes, and you can add a virtual crosshair, frame rate counter, or timer on the screen. In addition to having a flicker-free backlight, it has a blue light filter that can also help reduce eye strain. Last but not least, you need a graphics card that supports Display Stream Compression over a DisplayPort connection to achieve the full 144Hz refresh rate because there's no HDMI 2.1 port.
If you find the ASUS ROG Strix XG27UQ too expensive, then check out the LG 27GN950-B. It's a very similar 4k IPS monitor with a 144Hz refresh rate, but there are a couple of differences. It has better viewing angles, faster response time, and better accuracy out of the box. However, it has worse ergonomics and doesn't handle reflections well. On the upside, it gets a lot brighter in HDR.
For most people, the ASUS is better overall due to its superior ergonomics and reflection handling. However, if you're shopping on a smaller budget, the LG has a better response time and is a great alternative.
The best HDR 4k monitor in the budget category that we've tested is the Dell S2721QS. It's a versatile model with a simple design that fits easily into most settings. It has a 27 inch screen that provides plenty of space for multitasking, allowing you to have multiple windows opened side-by-side. It has wide viewing angles so that images remain accurate when viewed from the side, and it provides good visibility in bright lighting conditions.
The HDR color gamut is decent. It has great coverage of the DCI P3 color space used in most HDR content, but it just doesn't get bright enough to produce vibrant colors and make highlights pop. Also, it has a contrast ratio that makes blacks appear gray, and it lacks a local dimming feature. It has good response time and low input lag, and it supports variable refresh rate technology to reduce screen tearing when gaming.
There are only a few additional features. It has a pair of built-in speakers if you don't already have dedicated ones, and it has a Picture-in-Picture mode that lets you display two input signals at once, which can be useful for those working on two computers. Overall, this is a great, wallet-friendly monitor that should satisfy most people.
