Although 4k TVs are becoming very common, 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.

We've reviewed over 125 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 LG 27UK650-W is the best 4k monitor that we've tested. It's a versatile option that's primarily designed for office use, but with enough gaming performance to satisfy most gamers. Its 4k resolution and 27 inch screen size result in a high pixel density, producing sharp text and detailed images. It has an IPS panel with wide viewing angles, making it easy to share work or content. Reflection handling is decent, and it gets bright enough to fight glare in well-lit environments. Unfortunately, while it has height and tilt adjustment and can rotate to portrait mode, it can't swivel at all.

    It delivers good picture quality. It has great color accuracy out-of-the-box, near full coverage of the sRGB color space, and superb gradient handling. It has a great response time to deliver clear images in fast-moving scenes, and exceptionally low input lag for a responsive desktop and gaming experience. The refresh rate is limited to 60Hz; however, it shouldn't be an issue for most people, as 4k gaming is still incredibly demanding on the graphics card. It has native FreeSync support to minimize screen tearing and is compatible with NVIDIA's G-SYNC too.

    There aren't many extra features, only a black stabilizer feature that makes objects more visible in dark scenes, and a super-resolution feature to upscale lower resolution content. It has HDR support, but it can't display a wide color gamut and doesn't get bright enough to make specular highlights pop in HDR content. On the upside, it has a flicker-free backlight that can help reduce eye strain. All in all, it's a well-rounded monitor that should satisfy most people.

  2. Cheaper Alternative: LG 27UD58-B

    Size 27"
    Resolution 3840x2160
    Refresh Rate 60 Hz
    LCD Type
    IPS
    Variable Refresh Rate
    FreeSync

    If you're shopping on a smaller budget, then check out the LG 27UD58-B. It doesn't look as sleek as the LG 27UK650-W with its thick bezels and glossy plastic stand, but you're still getting a 4k resolution and 27 inch screen at a more affordable price. It also has great color accuracy, a fast response time, and variable refresh rate support to reduce screen tearing when gaming. Unfortunately, there are some compromises. The stand has extremely limited ergonomics and only allows for tilt adjustment. Also, it doesn't get as bright and has narrower viewing angles.

    Overall, the 27UK650-W is a better choice due to its superior ergonomics, higher brightness, and wider viewing angles. However, if cost is a concern, the 27UD58-B is a very decent alternative.

  3. Best 4k Monitor For HDR: Acer Predator X27

    Variable Refresh Rate
    G-SYNC

    The best 4k monitor for watching HDR content that we've tested is the Acer Predator X27. It has a 27 inch screen that provides plenty of space to have multiple windows opened side-by-side, and it delivers a stunning HDR experience with its high peak brightness and wide color gamut. It's impressively well-built, it has wide viewing angles, and although its reflection handling is only decent, it gets more than bright enough to overcome glare easily. Unfortunately, its ergonomics are mediocre, as it can't rotate to portrait mode, and the swivel range is narrow.

    Even though it's been on the market since 2018, it remains one of the few 4k 120Hz options available. The high refresh rate makes motion look incredibly smooth, and there's minimal motion blur in fast-moving scenes thanks to its quick response time. It has excellent coverage of the DCI P3 color space to deliver images with vivid colors; however, it can't produce dark colors well due to its low contrast ratio, which is expected of most IPS panels. Its low contrast also makes blacks look gray, which isn't ideal for dark room viewing.

    If you want to game on it, the good news is that it has extremely low input lag, and it supports G-SYNC to help minimize screen tearing. It has a pair of built-in speakers, a generous number of USB ports, and even some RGB lighting on the back. Its near full coverage of the Adobe RGB color space makes it suitable for photo editing, and the backlight is flicker-free. If you want the best HDR experience on a monitor, this is the one to get, as long as you don't mind the high price tag.

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

    Pixel Type
    IPS
    Variable Refresh Rate
    FreeSync

    The best 32 inch 4k monitor that we've tested is the LG 32UD99-W. This is a good option for those who like the traditional 16:9 aspect ratio but still want enough screen real estate to have multiple windows opened at the same time. Its 4k resolution keeps text looking sharp and easy to read, and its excellent low input lag provides a responsive desktop experience. If you want to game on it, it supports FreeSync to reduce screen tearing, but it also has a limited 60Hz refresh rate.

    For most bright rooms, it has a great peak brightness that fights glare easily. However, its reflection handling is sub-par, so it's best to avoid direct sources of light shining on the screen. It has a decent color accuracy right out of the box, with full coverage of the sRGB color space, and it supports HDR. When viewed from the side, images remain accurate thanks to its IPS panel's wide viewing angles, but its low contrast ratio results in blacks that look gray.

    Like many ultrawides, it supports a Picture-by-Picture mode that allows you to display an image from two sources simultaneously. Its USB hub also includes a USB-C port with DisplayPort Alt mode, so you can use it as a second screen for a compatible device like a MacBook Pro and charge it with a single cable. All in all, if you want a large 16:9 monitor with a 4k resolution, consider this one.

  5. Dark Room Alternative: BenQ EW3270U

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

    If you're looking for something that performs better in dark rooms, check out the BenQ EW3270U. Because it includes a VA panel, it doesn't have the same wide viewing angles as the LG 32UD99-W's IPS panel, but it has a much better contrast ratio and better black uniformity. It also has better gaming features thanks to its good response time and excellent low input lag. That, combined with its 4k resolution, means you'll have an immersive gaming experience. Unfortunately, it doesn't perform very well in bright rooms, with only a decent SDR peak brightness, but it still has good reflection handling if you choose to put it in a bright environment.

    If you're looking for the best 32 inch 4k monitor that we've tested, consider the LG, but if you want a dark room alternative, look into the BenQ.

  6. Cheaper Alternative: LG 32UD59-B

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

    If you find the LG 32UD99-W a bit too expensive, there's a cheaper option, the LG 32UD59-B. It also has a 32 inch screen, a 16:9 aspect ratio, and a 60Hz refresh rate. However, it uses a VA panel, which has a much higher contrast ratio to produce deeper blacks, but its viewing angles are significantly worse. It should perform fine in most rooms, as it has an okay peak brightness and decent reflection handling, but it may be an issue in very bright rooms. Unfortunately, it has rather poor ergonomics, with only height and tilt adjustments available, and it doesn't support HDR. That said, it still has a 10-bit panel with outstanding gradient handling and good out-of-the-box color accuracy.

    Overall, the 32UD99-W has many more features and performs better in general, but if you're shopping on a tight budget, the 32UD59-B is a good alternative.
