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 just 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 100 monitors, and below are our recommendations for the best 4k monitors that are available for purchase. See our recommendations for the best 4k gaming monitors, and the best 1080p and 1440p monitors.

    The best 4k monitor we've tested so far is the LG 27UK650-W. This modern, stylish monitor is a great addition to any professional office setting and it's also very competent when it comes to gaming. It's decently well-built but its ergonomics are somewhat limited, as it lacks swivel adjustment and the tilt range is pretty narrow. You can still use it in portrait mode, which is great, and there's simple cable management to keep everything neat and tidy.

    At such a high resolution, it's not a surprise that everything looks incredibly sharp and detailed. The 27 inch screen provides plenty of space for an efficient workflow, as well as delivering an immersive gaming experience. Its response time is impressive, input lag is low, and its FreeSync support is a welcome addition for those with an AMD graphics card or an Xbox One. Its 10-bit panel has near-perfect gradient handling and there's no sign of color bleed at all, but unfortunately, it can't display a wide color gamut despite having HDR support.

    When it comes to visibility, this monitor is best used in an averagely-lit room. It can get fairly bright, enough to combat glare, but its reflection handling is only decent and may not be able to handle direct sunlight. Viewing angles are great, which is expected of most IPS panels; however, it doesn't look good in the dark, as it has quite a bit of backlight bleed and the contrast ratio is low. On the whole, this is a versatile monitor that can do a lot, just don't expect a stunning HDR movie watching experience.

  2. Cheaper Alternative: LG 27UD58-B

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

    If you're looking for something a bit cheaper, check out the LG 27UD58-B. It looks very similar to the LG 27UK650-W, except that it has a glossy black finish and the bezels are slightly thicker. This is a 27 inch monitor with a 60Hz refresh rate, and it has excellent input lag and FreeSync support. The main differences are that it can't get as bright, its viewing angles aren't as good, and its ergonomics are significantly worse, allowing only for tilt adjustments. Also, its response time is marginally slower and it doesn't support HDR. However, given the limited HDR performance on the other LG, you're not missing much.

    Overall, if you care about ergonomics or you want a brighter screen, go with the 27UK650-B; otherwise, the 27UD58-B is just a minor step down in performance and it can help you save some money.

    Variable Refresh Rate
    G-SYNC

    If you want the best HDR experience, the Acer Predator X27 is one of the best 4k monitors we've tested that supports HDR. It has an impressive color gamut, making it a great choice if you do a lot of professional photo or video editing in the wider Adobe RGB color space. This monitor is also extremely bright and has excellent motion handling, making it one of the most versatile monitors that we've reviewed so far.

    It's a great gaming monitor as well, with excellent low input lag and fast response time. It has excellent wide viewing angles, perfect for co-op gaming. The monitor also supports G-SYNC and has a wider refresh rate range than the vast majority of 4k monitors on the market, though you'll need a very powerful graphics card to take advantage of it.

    Unfortunately, this monitor doesn't look the best in a dark room. It has a disappointing native contrast ratio, so blacks appear gray in this situation. It does have a local dimming feature, but it isn't very effective. Overall, although this monitor is very expensive, it's great and should please most people.

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

    Resolution 3840x2160
    Max Refresh Rate
    60 Hz
    LCD Type
    IPS
    Variable Refresh Rate
    FreeSync

    The best 32 inch 4k monitor that we've tested so far is the LG 32UD99-W. This is a great monitor 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 legible, and its excellent low input lag provides a responsive desktop experience. If you want to do some gaming on this monitor, it supports FreeSync to reduce screen tearing, but it also has a limited 60Hz refresh rate.

    For most bright rooms, this monitor has an impressive 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. Images remain accurate when viewed from the side thanks to its IPS panel's wide viewing angles, but its low contrast ratio results in blacks that look like gray.

    Like many ultrawide monitors, 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 monitor 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, you should consider this one.

  5. Dark Room Alternative: BenQ EW3270U

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

    If you're looking for a monitor that performs better in dark rooms, check out the BenQ EW3270U. With 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 with good response time and fantastic low input lag, so with the 4k resolution, you'll have an immersive gaming experience. Unfortunately, this monitor doesn't perform very well in bright rooms with 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 we've tested so far, 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, this monitor uses a VA panel, which has a much higher contrast ratio to produce deeper blacks. Its viewing angles are significantly worse, causing images to look washed out when viewed from the side. Visibility should be fine in most rooms, as it has a decent peak brightness and reflection handling, but it may be an issue in very bright rooms. Unfortunately, this monitor has rather poor ergonomics, with only height and tilt adjustments available, and it doesn't support HDR. That said, you're still getting a monitor with a 10-bit panel, outstanding gradient performance, and good color accuracy.

    Overall, the 32UD99-W has many more features and it performs better in general, but if you're shopping on a tight budget, then the 32UD59-B is a good alternative, although there are a few compromises to be made.
