Best 4K Monitors 2021 for Gaming, Home Office, Movies, and Ultra Wide sizes

Today I recommend The Best 4K Monitors 2021 for Gaming, Home Office, Movies, and Ultra Wide sizes. People increasingly prefer to use 4K monitors, because 4K monitors not only have high definition but also give users a very good viewing experience. 
best-4k-monitors
First of all, let’s first understand what a “4K” monitor is. 
  • 4K refers to the resolution of the monitor screen. HD (1280×720) is called 720p, 
  • and when full HD (1920×1080) appears, it is also called 1080p. 
  • The aspect ratio of 4K is usually (4096×2160), which is considered as Ultra HD or UHD. 
The vertical and horizontal pixels of 4K media are about twice that of 1080p, so its picture quality is much clearer than 1080p. 

Let’s take a look at the best 4K monitors in 2021:

    Although this Dell Ultrasharp U2718Q is not entirely a dedicated monitor, it actually provides a good gaming monitor function in this price range. Because its input signal reacts quickly, it has a good display effect for the fast pace of the game. And its color gamut is also very wide, very suitable for photo editing, it has a wide viewing angle and good contrast.

    • FreeSync / G-Sync : FreeSync
    This Samsung monitor is similar to the BenQ above, but this one does not have HDR and USB-C ports and is cheap. Although the appearance of this monitor is very stylish, it does not have a very slender frame like many monitors, so if you put several monitors together, its frame may be distracting.

    It is very similar to BenQ EW3270U. It has excellent color reproduction. The picture looks great in a dark room, but if it is in a well-lit room, its brightness does not feel high enough. From the price point of view, it is a good 32-inch monitor for playing games.

    • Aspect ratio:  16:9 (normal)
    • Connectivity:  DisplayPort, HDMI 1.4, HDMI 2.0
    • FreeSync / G-Sync:  N / A
    AOC performs very well in the U2790VQ display. While providing a beautiful design, it also provides excellent color performance and 4K clarity. Of course, at this price point, it does not provide all the fancy features, but compared with the same model, it can save a lot of money.

    Although it doesn't have HDR and the like, its color gamut is very good, and it is definitely a good choice for Photoshop work. It is fair to say that although this is a far cry from high-end gaming monitors, you can still use it to play 4K games. 

    Its price is very competitive, but its disadvantage is that it does not have a USB-C interface. If the lack of a USB-C interface will not affect you, and if your budget is limited, then U2790VQ is a very reliable choice.

    • Panel type: IPS

    • FreeSync / G-Sync:  N / A
    HP Business Z27 is very affordable in price, and it provides additional USB-C connectivity, which is very convenient. In terms of price, its color accuracy is also first-class, and its bracket can be adjusted, has a good ergonomic design, and is very convenient to use.

    It is named after the word "business monitor", and its design is very simple and generous, very suitable for office use. Despite its soft appearance, it is indeed very stylish, and if you are going to use multiple monitors, it is also suitable because of its very narrow bezel.

    It provides different display modes, such as "low blue light mode" and "night mode", which reduces eye fatigue during long and late-night meetings. One thing to note though is that it has no built-in speakers, so you might want to consider this. 

    If you are a hardcore gamer or need absolutely perfect color reproduction ability, it is not a good choice. However, if you are looking for a beautiful, powerful and inexpensive 4k monitor, HP Business Z27 should definitely be in your consideration. 



    8. LG 34WN80C-B 34″Curved UltraWide IPS Monitor 


    best-4k-monitors

    • Panel type: IPS
    • Refresh rate: 60hz
    • Aspect ratio:  21:9 (ultra wide)
    • Connectivity:  Thunderbolt 3 / USB Type C port, DisplayPort, 2 HDMI, USB Type B, 2 USB Type A
    • FreeSync / G-Sync:  N / A
    This monitor is very spacious. To be honest, once you try to use this ultra-wide monitor, it will be difficult for you to return to a normal widescreen. Just like going from 1080p to 4K, once you use it, you will find the difference and you will be fascinated by this monitor.

    It is very suitable for game design, graphic design, photo editing, video editing, and other tasks. This monitor is also curved, so it is great for viewing, allowing you to fully focus on the content you are studying.
     
    And it is also very suitable for playing games and watching movies, and its panel is very sensitive, even if you do not have to worry about ghosting or blurring when playing fast-paced games. If you have an Nvidia graphics card, you can even increase the refresh rate to 75hz, so for its price point, this is a very ideal choice.

    If you want a monitor that has more professional uses, but still has good gaming performance, then LG 34WN80C-B is a very good choice. 



    9. LG 34BK95U-W 32″ IPS UltraWide Monitor 


    best-4k-monitors



    Feature:

    • Screen size: 32 inches
    • Panel type: IPS
    • Refresh rate: 60hz
    • Aspect ratio:  21:9 (ultra wide)
    • Connectivity:  Thunderbolt 3 / USB Type C port, DisplayPort, 2 HDMI, USB Type B, 2 USB Type A
    • FreeSync / G-Sync:  N / A
    At first glance, LG 34BK95U-W does not seem to be a big deal, but a closer look will reveal that it has an amazing resolution close to 5K, and it is actually not very accurate to call it a real 5K display. 

    Because even though it has 5120 lines of pixels on the horizontal axis, there are only 2160 lines on the vertical axis, which is higher than the resolution of a 4K display. Therefore, you can think of it as a 4.5K display, not 5K, but still much better than 4K!

    LG 34BK95U-W uses LG’s patented Nano IPS technology, which essentially means that its color intensity is higher and it enhances HDR support. In other words, it can clearly display the content and close-up details. 

    It has an ambient light sensor to adjust its brightness and color temperature to protect your eyes. If you are the owner of a Mac, then this LG monitor can also be used very well. And it is also very suitable for games. Whether it is for work, entertainment or playing games, it is a very good choice. 



    10. Dell U-Series 32″ Monitor 


    best-4k-monitors



    Feature:

    • Panel type: IPS
    • Refresh rate: 60hz
    • Aspect ratio:  16:9 (normal)
    • Connectivity:  HDMI, DisplayPort, USB-C
    • FreeSync / G-Sync:  N / A
    Dell U3219Q is designed for mixed-use, whether you are using it for office, playing games, or using multimedia to watch movies, videos, etc., it performs very well. 

    As an IPS panel, its input lag time is very short, so the display can be synchronized with the game effortlessly. It also has a very good perspective, so if you want to show your colleagues and friends what you are doing, there will be no trouble.

    It is a typical high-quality professional monitor, it does have very good ergonomic adjustments, and it also has very good color accuracy. Regrettably, HDR is not that compelling. 

    But this is the same for all-around 4k monitors, you can't find a perfect monitor. However, the multi-functional use of this monitor and its excellent large 32-inch form factor are already attractive enough to buy.

    • Screen size: 27 inches
    • Panel type: IPS
    • Refresh rate: 60hz

    14.  BenQ 32-Inch IPS 4K Monitor (BL3201PH) 


    best-4k-monitors



    Feature:

    • Screen size: 32 inches

    It is a sturdy and durable display that will not look boring or ugly. Matte black plastic decorates the frame, and the top and sides of the frame are quite thin, about 9 mm (0.35 inches). The bottom bezel is thicker, almost exactly 20 mm (0.79 inches). There is a "sensor kit" in the middle of the bottom frame, including the "Eye Protect" ambient light sensor and the "Eco" proximity sensor. 

    There are also proximity and touch-sensitive buttons on the right, which will light up when in use or when a finger is closed. The screen surface of this model uses a very light matte anti-glare, some users call it "semi-gloss." This provides a good balance between clarity and glare reduction.

    The panel provides excellent tonal variation and color consistency, with a rich color gamut and a pleasing smooth screen surface, which perfectly complements this. 

    The good static contrast performance and the relatively low level of "luminescence" help provide a pleasing contrast performance for this panel type, and the screen surface is one of the smoothest (least grained) frosted surfaces we have ever seen.

    It has a fast response time, low input delay, and 144Hz refresh rate, which can achieve smooth motion and incredible responsiveness. However, it requires a graphics card with display stream compression and a DisplayPort connection to achieve such a high refresh rate because it lacks an HDMI 2.1 port. 

    It supports adaptive synchronization and is compatible with FreeSync and G-SYNC. Its IPS panel has good reflection processing ability, and the brightness is enough to resist strong glare. 

    However, it is not suitable for dark rooms because its low contrast makes blacks look gray. It has a good wide color gamut and becomes quite bright in HDR. 



    FAQ about Best 4K Monitors 2021 


    What is a 4K display?

    A 4K display can often refer to a display with one of two high-definition resolutions. The most common 4K display has 3840 x 2160 pixels (refers to a display that is about 4000 pixels wide), and the number of pixels in rows and columns is exactly twice that of 1080p (1920 x 1080 pixels), which is four times the total number of pixels. , With the same 16:9 aspect ratio. A 4K display can also refer to a display with a resolution of 4096 x 2160 pixels that is not very common currently.


    What should I pay attention to when buying a 4K monitor?

    When you first look at a 4K monitor, you are likely to see a lot of specifications and numbers, and you will feel very big. But don’t worry, it’s actually much easier as long as you divide it into the following points to choose:

    1. Look at the screen size of the monitor:

    This is actually related to your preference. How big is your desk? How far do you like to be from the monitor? Currently, 4K monitors with screen sizes ranging from 27 to 32 inches are the mainstream, but you can also find 4K screens of different sizes that best suit your needs.

    2. Look at the panel type of the monitor:

    The panel describes how the screen displays the image. The main panel types are:
    • TN panel: Fast response time, very suitable for playing games. The most common type of panel, because it has the fastest response time, is very suitable for gamers. But the colors look a bit faded and the viewing angle is not good. Displays with TN panels are often the most affordable.
    • VA panel: high contrast, slow response, not suitable for playing e-sports games. It is sometimes called MVA or PVA panel. It has better colors and good viewing angles, but ghosting may occur. 
    • IPS panel: The color is good, and it is wider, which is very suitable for offices or games. A display with an IPS panel is often the most expensive display, but it has richer colors and a clear viewing angle close to the level.

    3. Look at the refresh rate of the monitor:

    You can think of the refresh rate as the degree of blur that appears when something moves quickly on a 4K screen. Most 4k displays have a frequency of about 30hz, which means that the display refreshes 30 times per second. It can be used for general purposes, but it is not good for the game due to too much blur.

    Some very, very high-end 4K monitors can reach 144hz, which shows very good performance in reducing blurring in games and videos. But please note that the higher the refresh rate, the higher the price of the 4K monitor (much more expensive).

    Unless you really want to play a competitive fast-paced game, a refresh rate of 30-60hz is fine.

    4. Look at the aspect ratio of the display:

    Most monitors have a 16:9 ratio, but there are also ultra-wide monitors that have a 21:9 ratio. Ultra-wide monitors are more expensive because they pack more pixels in the horizontal direction of the monitor. It can handle a lot of content and is very suitable for movies or games. Some high-end monitors like to stretch objects in a ratio of 21:9, but this is more suitable for specific work situations or hardcore games. Another common format is 16:10, which provides more vertical space to view multiple open documents or images. 3:2 is becoming more and more common in notebook computers, which can better browse the web, but it is rare on independent monitors.

    5. Look at the connectivity of the display :

    Find out which monitor connection types your desktop or laptop has, and make sure that the 4K monitor you are looking for is compatible. If you want 4k 60hz when you plug in a game console, you need HDMI 2.0. If you want to plug in a PC, DisplayPort is a better choice.

    6. See if you have FreeSync or G-Sync

    FreeSync and G-Sync are graphics/gaming technologies created by AMD and Nvidia respectively. To make a long story short, when you play a game or watch a video, both will reduce "screen tearing" and provide a better gaming experience.

    7. Look at the resolution of the monitor

    Common monitors have the following resolutions, the higher the resolution, the clearer the image
    • 1080p: If you want reasonable resolution, but want to save costs or focus on other more important functions, then 1080p is your ideal choice-as long as the monitor you buy is not very large. 1080p is an ideal choice for 21-inch to 24-inch displays. These computer monitors provide excellent image quality, and now they have bottomed out when they compete with 4K. However, if you want to be larger than 24 inches, you should at least consider a resolution of 2,560 x 1,440, so the effect will be better
    • 1440p: In the process of the gradual integration of consumers and 4K, 1440p, which is often forgotten, is still the recommended resolution for gamers because it provides obvious visual effects at 1080p, but does not excessively increase the burden on the graphics card. If you are interested in additional features such as a high refresh rate, its price is also much cheaper.
    • 4K: 4K is the resolution that the industry is most eager to drive consumers towards. It looks more detailed than 1080p, has 3840 x 2160 pixels, and the price has dropped significantly in the past few years. In other words, gamers will need a powerful graphics card to run the system at this resolution, and it is still difficult to find an affordable monitor with a full set of frame synchronization support or a high refresh rate monitor.
    • 5K: This resolution made headlines when it debuted on the Apple iMac, but it is far from becoming a universal resolution a few years later. The LG 27MD5KL is a beautiful-looking display, but we recommend using a 4K display, as there are not too many differences between them.
    • 8K: There are also some 8K monitors available, especially Dell's 8K Ultrasharp. There is no need for such a high-resolution display, but if a resolution is important to you, it may be worth considering.

    8. Look at the brightness of the display

    Today, the brightness of high-end displays is about 300 to 350 cd/m2. If you work in a well-lit room or next to a large window, it may be easier to get the extra brightness. However, too much brightness can cause eye fatigue. As long as the brightness option reaches 250 cd/m2, the display can be used. That is to say, if you want a display with HDR support, the more peak brightness, it is better to choose a display that supports HDR.

    9. Look at the corresponding time on the display

    The response time indicates the speed at which the monitor displays the image transition. Choosing a monitor with a short response time is a good choice for gamers. The response time is in milliseconds. The best screens can switch pixels within a few milliseconds, but not everyone needs such a fast response speed.


    What are the common interfaces of monitors?
