Although 4k TVs are now the norm, 4k monitors are just starting to grow in popularity. Whether you're looking for a better multitasking experience for work or want a more immersive gaming experience, 4k monitors have a lot to offer. Although they used to be very expensive, they have recently started to drop in price as 4k becomes more popular and more devices support it, and as computers and graphics cards have improved.

We've tested over 180 monitors, and below are our recommendations for the best 4k monitors that are available for purchase. Also, check out our recommendations for the best 4k gaming monitors and the best 1080p and 1440p monitors.

    The Best 4k monitor for office use that we've tested is the Dell S2721QS. It's an impressive office monitor with wide viewing angles, good ergonomics, and exceptional text clarity. The versatile stand makes it easy to adjust it to an ideal viewing position, and it can switch to portrait orientation, great for a dual-monitor setup.

    It looks great in most offices. It has very good reflection handling and great peak brightness, so glare shouldn't be an issue in a brighter room. It also has wide viewing angles, so you can comfortably share your screen with someone else without worrying that they're seeing an inaccurate image. Combined with the outstanding color gamut, this monitor is also a great choice for media creators.

    This monitor isn't perfect, though, as it has limited connectivity. There are two HDMI ports and a single DisplayPort input, but no USB ports. It's also not as good for gaming, as it has a limited 60Hz refresh rate and a slower pixel response time than most dedicated gaming monitors. Overall, though, this is a great monitor for almost any usage.

    Variable Refresh Rate

    The best 4k monitor for gaming that we've tested is the Acer Nitro XV282K KVbmiipruzx. It's an excellent gaming monitor, with a fast refresh rate, support for FreeSync variable refresh rate technology, and incredibly low input lag. It has an extremely fast response time, resulting in crystal-clear motion, with almost no noticeable blur or overshoot behind fast-moving objects.

    It also happens to be one of the first monitors on the market to support HDMI 2.1. This new technology allows for higher refresh rates and higher resolutions over HDMI, something that used to be reserved for DisplayPort connections. This makes it an excellent choice for next-gen consoles, like the Sony PlayStation 5 or the Xbox Series X, or if you have a recent graphics card, like the 30-Series cards by NVIDIA.

    Although it's an excellent gaming monitor, it has some limitations. This isn't the best choice for a dark room, as it has a low contrast ratio, and although it has a local dimming feature, it's pretty bad. If you're not in a dark room, though, it's an amazing gaming monitor. When you're not gaming, it also has superb text clarity, excellent gray uniformity, and fantastic gradient handling. Overall, it's an impressive monitor for pretty much any usage.

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

    Variable Refresh Rate
    Adaptive Sync

    The best 4k monitor for HDR gaming that we've tested is the ASUS ROG Strix XG27UQ. It's a high-end model that's a bit on the costly side, but if you want a better HDR experience than some other monitors, this one won't be disappointing. It's packed with gaming features, including HDR10 support, and it displays the wide color gamut needed for HDR content.

    It has a high 144Hz refresh rate with an incredible response time for clear motion. However, with the lack of HDMI 2.1 support, you can only achieve its high frame rate with its 4k resolution over a DisplayPort connection with VESA Display Stream Compression. It's tested to be compatible with both FreeSync and G-SYNC to reduce screen tearing, and it has very low input lag. If you also plan on gaming at 60Hz, it still has a quick response time, so fast-moving content shouldn't have any motion blur. It also has fairly wide viewing angles and good ergonomics, making it a good choice if you want to use it for co-op gaming.

    Unfortunately, its IPS panel has a low contrast ratio that makes blacks look gray when viewing in the dark. It has an edge-lit local dimming feature, but it doesn't do much to improve the contrast because there are minimal dimming zones. Still, if you want to use it for HDR gaming, it has decent peak brightness, enough to make some highlights stand out. Overall, this is one of the best 4k monitors we've tested.

  4. Larger Alternative: LG OLED48CXPUB

    Size 48"
    Resolution 3840x2160
    Max Refresh Rate
    120 Hz
    Pixel Type
    OLED
    Variable Refresh Rate
    FreeSync

    If you want something bigger, then look into the LG OLED48CXPUB. This is a TV that we tested as a monitor, so it doesn't have an ergonomic stand like the ASUS ROG Strix XG27UQ. However, with its OLED panel, it can individually turn off pixels, resulting in an infinite contrast ratio and perfect black uniformity, making it a fantastic choice for dark room gaming. Thanks to its HDMI 2.1 support, you can easily connect your PS5 or Xbox Series X and play 4k @ 120Hz games in HDR. It supports Dolby Vision and HDR10 and displays a wide color gamut, but once again, its HDR peak brightness is just decent, so colors may not pop how the creator intended. Sadly, OLEDs have the risk of permanent burn-in, so we suggest watching varied content if you're going to use it as a monitor.

    All things considered, the ASUS is the best 4k monitor for HDR gaming, but if you plan on using it for watching varied content and don't mind the risk of permanent burn-in, check out the LG.

  5. Best 32 Inch 4k Monitor: LG 32UD99-W

    Variable Refresh Rate
    FreeSync

    The best 4k monitor with a 32 inch screen we've tested is the LG 32UD99-W. It's a versatile IPS monitor with a sleek design that fits easily into most settings. It has good viewing angles so that you don't lose image accuracy from the side, which is great for sharing the screen with others. You can adjust the height and tilt, as well as rotate to portrait mode, but unfortunately, it can't swivel at all.

    It delivers incredibly sharp text and images because it has a high pixel density. It covers the entire sRGB color space, and it also supports a wide color gamut, with impressive DCI P3 coverage, the color space used in most HDR content. Its response time is a bit slow but good enough for some casual gaming on the side, and there's even FreeSync support to minimize screen tearing.

    The USB-C input supports DisplayPort Alt Mode, which lets you dock a compatible device and charge it simultaneously with a single USB-C cable. Max power delivery is 60W, enough for an ultraportable laptop but not power-hungry ones with a dedicated GPU. Sadly, while its contrast ratio is better than most IPS panels, blacks still look gray, so it's not the best choice for dark rooms. Nonetheless, this is a great office monitor that should please most people.

  6. Dark Room Alternative: Dell S3221QS

    Size 32"
    Resolution 3840x2160
    Max Refresh Rate
    60 Hz
    Pixel Type
    VA
    Variable Refresh Rate
    FreeSync

    If you want a monitor that's better suited for dark rooms, then go with the Dell S3221QS. Like the LG 32UD99-W, it's a 32 inch 4k monitor. However, it's curved, and its VA panel has a much higher contrast ratio, which results in deeper blacks. Its viewing angles aren't bad for a VA panel, although there's still some loss of image accuracy when viewing from the side, so it isn't ideal for sharing work that requires accurate color reproduction. Unfortunately, even though it has low input lag and VRR support, the response times are quite slow, making fast-moving scenes look blurry. Also, it doesn't rotate to portrait mode and lacks USB-C input. On the upside, you still get built-in speakers, two USB 3.0 ports, and a Picture-in-Picture/Picture-by-Picture mode.

    The LG is a better monitor overall. It has wider viewing angles, better ergonomics, USB-C input, and a brighter screen to combat glare. However, if dark room performance is important to you, the Dell is also a good choice.
