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 15 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.


  1. Best 4k HDR Gaming Monitor: ASUS ROG Strix XG27UQ

    8.6
    Gaming
    Size 27"
    Resolution 3840x2160
    Max Refresh Rate
    144 Hz

    IPS
    Variable Refresh Rate
    Adaptive Sync

    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.

  2. Cheaper Alternative: LG 27GN950-B

    Size 27"
    Resolution 3840x2160
    Max Refresh Rate
    160 Hz
    Pixel Type
    IPS
    Variable Refresh Rate
    FreeSync

    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, but its refresh rate can be overclocked up to 160Hz. 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 LG 48 CX OLED is the best HDR monitor for dark room viewing we've tested. This TV is well-suited for use as a PC monitor, and it delivers an amazing HDR experience. Like all OLEDs, it can turn off individual pixels to produce perfect blacks, making it a fantastic choice for watching HDR content in the dark. Black uniformity is perfect, and since it doesn't require a backlight, there's no blooming around bright objects and subtitles. The viewing angles are excellent, but you might have a hard time placing the screen at your preferred viewing position because it doesn't allow for any ergonomic adjustments.

    It has excellent DCI P3 coverage, the color gamut used in most HDR content, allowing it to produce rich and vibrant colors. It gets decently bright in HDR and can bring out some highlights, particularly in dark scenes. Fast motion looks clear and smooth thanks to its near-instantaneous response times and 120Hz refresh rate, and it also has a Black Frame Insertion feature to further improve clarity. It has low input lag, VRR support, and HDMI 2.1 ports, which is great for gaming on consoles like the PS5 and Xbox Series X.

    Unfortunately, there are risks of permanent burn-in with OLEDs, and this is no exception. That said, it shouldn't be an issue as long as you watch varied content, and there are features built-in to help avoid burn-in. Color accuracy is mediocre out of the box, so you might need to calibrate it to get the best viewing experience. Overall, although it isn't technically a monitor, most people should be happy with it nonetheless.

  4. LED Alternative: Philips 436M6VBPAB

    Size 43"
    Resolution 3840x2160
    Max Refresh Rate
    60 Hz
    Pixel Type
    VA
    Variable Refresh Rate
    FreeSync

    If you're concerned about burn-in on the LG 48 CX OLED, then check out the Philips Momentum 436M6VBPAB. It's a 43 inch VA panel monitor with an exceptional contrast ratio, which means that it can produce deep blacks for a good dark room viewing experience. It has a great color gamut and gets brighter to make highlights pop in HDR, but it has a terrible edge-lit local dimming feature that can be somewhat distracting in dark scenes. Sadly, the refresh rate is limited to 60Hz, and response times are only decent. On the upside, it has features that the LG lacks, like a USB-C port with DisplayPort Alt Mode and a Picture-in-Picture/Picture-by-Picture mode.

    Overall, the LG is a better choice for dark rooms because it can produce perfect blacks with its near-infinite contrast ratio. However, if you're worried about burn-in, then you should go with the Philips.

    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 a 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.
