As 4K monitors become more ubiquitous, it may be difficult to pick out the best ones from the flood of new offerings. With well-known companies like LG, Phillips, Asus, and Dell all offering panels, together with lesser-known brands like BenQ and ViewSonic, it may be hard to decide which best suits your needs.
Fortunately, we've taken the guesswork out of it by reviewing and researching each 4K display, evaluating them based on design, screen size and quality, and extra features like split-screen that make them better to use for productivity. You should also take a look at our general computer monitor list to see if any them suit you.
Low input lag
No USB ports or speakers
Available with FreeSync technology which provides similar benefits to Vsync without losing performance, the LG 27UD58-B 27-inch 4K monitor is the best you can get without spending an arm and a leg. Designed with gamers in mind, the 3840 x 2160 pixel resolution offers more than four times the resolution of Full HD and has more than 8.3 million pixels on the screen. Our tester used it to play in Game Mode, taking advantage of the customized and optimized game settings, together with FreeSync.
Beyond gaming, multitasking lovers will find a use for Screen Split 2.0, which allows for the display of multiple windows at once, including four different picture-in-picture (PIP) options.
"While this particular display does cut a few corners, it still makes a great option for those looking to purchase a sub-$300 4K monitor." — Zach Sweat, Product Tester

Solid out-of-box calibration
Made with creative types in mind, the BenQ PD3200U is a beautiful 32-inch 4K monitor that features vivid colors and ideal viewing angles. With modes such as Darkroom, computer-aided design and computer-aided manufacturing (CAD/CAM) and Animation, the BenQ has a unique set of display settings that can provide a more efficient work environment, all with stunning color precision. Past the different modes, the BenQ also allows users to display and control content on two separate PC systems on one monitor with just one keyboard and mouse. Our tester found it ideal for developing, editing, and just generally working on.
Moreover, the ergonomic design is made for tilting, pivoting and swiveling the monitor to find the perfect orientation in both vertical and horizontal mode. Well equipped with ports and a strong stand, the BenQ is a creative’s dream monitor.
"The PD3200U is a 32-inch UHD monitor packed with great features for professionals to utilize and enhance their work." — Zach Sweat, Product Tester
Very affordable 4K
Who says an Ultra HD monitor has to be ultra-expensive? If you’re in need of a low-cost resolution bump, check out the Philips 276E8VJSB. This 27-inch monitor has an 8-bit IPS matte panel that uses a technique called frame rate control (FRC) to simulate HDR-like quality. That means you’ll get over the one billion mark for color count, but it’s not true HDR. Regardless, this monitor produces a dreamy picture for your games and movies.
Another benefit of that IPS nature is a wide viewing angle, allowing you to view the display at extreme angles with little picture degradation. The refresh rate tops out at 60hz, at 4K resolutions, most won’t be able to hit crazy frame rates beyond that anyway. You’ll also find faster response time in other monitors, but 5ms is still very respectable and usable for all but the most hardcore pro gamers and graphics designers.
As for design, Philips uses a borderless bezel. All but the bottom edge are thin enough to place multiple monitors side-by-side for seamless continuation. The included adjustable stand can be awkward to fit on a desk, but there are 100x100mm VESA holes on the rear for mounting. Speaking of rear-facing components, you have your choice of DisplayPort 1.2 or two HDMI 2.0 connectors, one of which supports HDMI audio out for more sophisticated home theater needs.
Performs poorly in bright environments
No ergonomic options
Boasting a 43-inch display with a 10-bit IPS panel, the massive Philips BDM4350UC 4K monitor is a great all-purpose option. Featuring a 5ms response time, there’s also a slew of connections, including fast charging, four USB 3.0 ports, two Display Ports, two HDMI 2.0 ports with MHL and audio in/out. The latter is most notable since the Philips includes dual seven-watt speakers built-in. Its large size is appropriately matched with MultiView, which enables the screen to be split into four separate Full HD displays (you can also utilize picture-in-picture mode for more ways to make use of the space). Our reviewer used this feature to good effect for multitasking and productivity.
The 178-degree viewing angle allows the 43-inch display to be properly viewed from almost any side while still providing bright colors for photos, movies, Web browsing and professional applications where color accuracy is critical.
"Typically, larger displays like these for computers can easily add lots of additional cost to the price, but Philips has used some smart cost-saving strategies to lower the price significantly." — Zach Sweat, Product Tester
Excellent build quality
Superb adjustment options
You won’t see many frills or flashy aesthetics on the Dell UltraSharp Monitor U3219Q, but its sleek, minimal look fits right in to any home or office. More importantly, you’ll feel and appreciate the high-quality build and functional, ergonomic design.
The 32-inch thinly-bordered screen offers plenty of viewing real estate while remaining slim and relatively lightweight with a small footprint. With VESA-mount compatibility, you can ditch the stand and mount it on the wall to save even more space. Our reviewer praised the big, beautiful screen for how well it suited businesses and creatives.
The Dell U3219Q was designed to be flexible and comfortable for the user as well. It can be adjusted in almost any way—it tilts forward and back, swivels 30 degrees each way, and adjusts more than five inches up and down. It can also pivot 90 degrees to be used in portrait mode. Connectivity options are plentiful, with a highlight being a USB-C port and included cable. Connecting to laptops and mobile devices via USB-C also serves to charge them with 90 watts of power, helping reduce cord clutter at your workstation.
Picture quality remains an important factor, of course, and your eyes won’t be disappointed by what you see on this 4K IPS display. With HDR support and great color and brightness, the Dell U3219Q looks excellent on-screen and off.
"Right out of the box, the U3219Q has great color accuracy in the standard mode, but this can be enhanced even more with a little adjusting." — Zach Sweat, Product Tester
Limited to 60Hz
As a 4K monitor with a 32-inch screen and support for high dynamic range (HDR) technology, the LG 32UD99-W can serve a wide range of personal or business needs. In-plane switching (IPS) technology on the panel helps deliver wide viewing angles and accurate color reproduction. 4K video comes through crisp and bright, whether HDR mode is on or not. The 3840 x 2160 resolution on the large display is ideal for multitasking, productivity work, and editing photos or videos.
The monitor also offers a great-looking experience for PC and console gamers alike. Its standard 60Hz refresh rate may be limiting for people serious about e-sports, but AMD FreeSync support for compatible graphics cards keeps the action smooth and stutter-free enough for most. Thanks to its excellent low input lag, everything feels quick and responsive as well.
Other features the LG 32UD99-W includes are a set of built-in speakers and on-screen control software for picture settings and screen splitting. The USB-C port’s 60-watt charging power is limited, but it’s a nice addition that adds to the powerful machine’s versatility.
"Ultrawide and curved monitors like the LG 32UD99-W are great for immersing yourself in games and working across multiple browsers and documents making them ideal for entertainment and productivity alike." —Ajay Kumar, Tech Editor
Fantastic refresh rate
4ms response time
A bit expensive
Today’s 4K monitors can combine stellar picture quality with smooth gaming performance, and the ASUS ROG Swift PG27UQ is leading the way. The 27-inch gaming monitor takes full advantage of its 4K resolution, IPS panel, and HDR capability to create a top-of-the-line visual experience.
While IPS monitors generally aren’t known for being the fastest options for gaming, the PG27UQ still boasts a 144-hertz refresh rate and a 4ms response time. It also supports Nvidia’s G-sync technology, so if you have a compatible graphics card, the monitor will match its frame rate on the fly to avoid screen tearing and stuttering.
Other features the monitor employs to ensure superb image quality include its 384 LED backlight zones. These work dynamically to display the darkest blacks and brightest whites—peaking at 1000 cd/m2 (or “nits”). The IPS display also uses quantum-dot technology to extend its color range to the cinema-quality DCI-P3 color gamut, which plays a big part in creating a premium visual experience other gaming monitors struggle to match.
VESA compatible mount
Multiple USB-A ports
Excellent picture quality
For users who want maximum screen space, the ViewSonic VX4380 43-inch 4K monitor is a no-brainer. Whether you’re gaming or watching a movie, the 4K resolution is beautiful. It adds 103ppi (pixels per inch) providing a sharp, crisp viewing experience with lifelike colors. The 178-degree viewing angles of the SuperClear IPS panel make it ideal to watch no matter where you are sitting in a room. Regardless of what you’re watching or reading, Flicker-Free technology and a blue light filter eliminate eye strain.
Designed with your multimedia needs in mind, the dual integrated 7W speakers significantly enhance audio. MultiPicture support allows simultaneous viewing of up to four video sources at once, each with immersive sound.
Capable of tilting between -5 and 12 degrees, the base is weighted to maintain full stability. The monitor is also VESA mount compatible, meaning it can also be removed from its base and fit onto a separately purchased monitor arm. Next to the VESA mount are dual HDMI 2.0 ports, three USB-A ports as well as DisplayPort 1.2 and mini DisplayPort 1.2 inputs.
Massive, curved panel
Low response speed
If you’re looking for a 4K monitor for business use, you probably want to get the most productivity out of your display. You will with the Dell 43 Multi-Client Monitor P4317Q—its main selling point is being able to efficiently take the place of four individual 21-inch monitors. Its massive 43-inch IPS panel can display content from one source at 4K resolution, or from four separate sources at full HD.
The four displays can be from any combination of sources, and small buttons in the bottom corner control settings to swap, rearrange, and zoom each display. Since it’s designed to take on a variety of inputs, the monitor has ports for HDMI, DisplayPort, USB 3.0, and more. Several corresponding cables are included, and a hole cut into the stand can help keeps them contained. Four mounting holes in the back support a VESA-compliant wall mount or monitor arm, which may be a good option given the desktop space it would take up otherwise.
The Dell P4317Q doesn’t prioritize gaming, as seen in its 60-hertz refresh rate and 8ms pixel response time that could produce some blurring or ghosting. But for office settings, it can certainly fit in a lot of work and display it on a bright, clear screen.
If you're looking for a good 4K monitor for work or play, our top pick is the LG 27UD58-B. This 27-inch monitor has low input lag, supports Freesync for gamers, and is quite inexpensive. It'll also do fine for productivity, though you may not want to do video or photo edits on it. For creatives, the BenQ PD3200U is big, beautiful, and has great color reproduction with modes that support Darkroom and CAD. The reasonable price is the cherry on top.
Zach Sweat has written for Lifewire since 2019 and he's previously been published on IGN and Void Media. With years of experience in tech, he reviewed many of the monitors on this list. The two he liked the best were the affordable LG 27UD58-B with its features for gamers and the gorgeous creative-oriented BenQ PD3200U.
Audio quality - Monitors are purely about apicture quality, right? Wrong! Whether you’re watching a movie or playing a video game, great audio can elevate the experience. Some monitors have impressive built-in speakers with as many as 9 watts. If the monitor lacks speakers, you can always add a soundbar — though that’ll cost you.
Design - Depending on your setup, you might need a monitor that tilts, pivots and rotates. A thin bezel gives a more modern look and the stand construction dictates how much desk space it will need. Consider all these design factors before you make a purchase.
Price - 4K is known for being expensive, but prices have dropped in recent years as it becomes the norm. If you’re on a budget, don’t fret. There are plenty of good options that run less than $300.
