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 200 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.

    The best 4k monitor for gaming that we've tested is the Gigabyte M28U. It sports a 28 inch screen that provides an immersive gaming experience and plenty of space for work. It has wide viewing angles so that the image remains accurate when viewed from the side, great for playing co-op games or sharing content. It handles reflections well, but its screen brightness is only decent, which means visibility might still be an issue in very well-lit, sunny rooms.

    It's impressive when it comes to gaming performance. The response time at its maximum refresh rate of 144Hz is exceptional, and even though it's slower at 60Hz, it's still great. It also has a black frame insertion feature that you can use simultaneously with VRR to improve motion clarity. It has two HDMI 2.1 ports, making it a good option for next-gen consoles like the PS5 and Xbox Series X. It has low input lag, but you'll need to update it to its latest firmware version to get the lowest input lag possible.

    Like its sibling, the Gigabyte M27Q, there are tons of extra features, like a Picture-in-Picture mode, a built-in KVM switch, and speakers. Its USB hub includes three USB 3.0 and a USB-C port. The latter supports DisplayPort Alt Mode so that you can dock a laptop and charge it with a single USB-C cable. The power delivery is limited to 15W, though, which is only enough for smaller mobile devices like smartphones. The Acer Nitro XV282K KVbmiipruzx is a better choice if you're willing to wait for availability; otherwise, this is the best 4k monitor for gaming available right now.

  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. 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 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: Dell S3221QS

    The best 4k monitor with a 32 inch screen we've tested is the Dell S3221QS. It's a curved VA monitor that can display deep blacks, so it's a good choice for people who like to work, game, or view content in the dark. It handles reflections well and gets pretty bright, but you might still have some problems with visibility if you're in a sunny environment. As expected of most VA panels, the viewing angles are mediocre, so it isn't ideal for sharing content because the image looks washed out from the side.

    Even at a 32 inch size, the pixel density is still very high, which results in exceptional text clarity. It has full sRGB coverage and decent calibration out of the box, and it also supports a wide color gamut for HDR content. Since it's primarily intended for productivity, it has a 60Hz refresh rate, and its response time is only decent, but it does support VRR to reduce screen tearing. As for the overall HDR experience, it's just okay because it doesn't get bright enough to make highlights pop, and it lacks local dimming.

    There are many extra features, like built-in speakers, a Picture-in-Picture mode, as well as a USB hub that includes two USB 3.0 and a USB-B upstream port so that you can plug your peripherals directly into the monitor for a cleaner setup. Unfortunately, the ergonomics are bad because you can only adjust the height and tilt. Overall, this is a good monitor for everyday use and should please most people. If you want a more gaming-oriented 32 inch monitor with a high refresh rate, check out the Gigabyte AORUS FI32U, but it may be hard to find at this time.
