What is 4K display?

- May 11, 2019-

4K display or Ultra HD offers enough pixels to fill four Full HD 1080p screens. With the 4K screens are definitely better for editing photos, playing games and watching videos. Furthermore, with four times the amount of pixels, the display is able to show four times the level of detail. However, everything from the cable to applications you use can cause impact on your experiences of 4K displays.

4K Resolution

First of all, what is a 4K display? 4K simply means a clearer picture, it offers more pixels on the screen. Nowadays, the industry named 1080p resolution after image height, and named 4K after image width. The pixels of 4K display create images that are crisper and capable of showing more details than standard HD display. With HD 1080p screens, the images offer only a 1920 x 1080 resolution while 4K screens provide about 8 million pixels. On the other hand, it means users can fit every pixel from 1080p set onto one quarter of a 4K screen.Therefore, 4K resolution provide double times what the current 1080p set can display.4K-display

Furthermore, 4K displays come with a native resolution of 3840 x 2160. To compare 4K with 1080p, with all other things being equal, 4K displays provide capable of producing much sharper and detailed images. Moreover, when editing photos in a 4K display, it will not caused the photos scaling. On the other hand, the 4K displays offer unscaled images and benefit many creative professionals in workplaces. For instance, Acnodes’ industrials 4K rackmount monitor for industries professionals will be a good choice, RMW7176.

However, having all the pixels from 4K display may caused issues in some scenarios. For example, For instances, everyday computing tasks such as web browsing or paperwork typing all work great with 4K displays. Furthermore, with gamers it will be a different story. MOreover, gamers need powerful graphics card to achieve playable frame rates at 4K resolutions.

LCD Panel Type

With current crop of 4K monitors employ an range of different panel types. Such as TN (Twisted Nematic), IPS (In-Plane Switching), and IGZO (Indium Gallium Zinc Oxide) panel types. Next, the prices ranged from TN panels for the lowest prices and then IPS panels and IGZO.

Typically, TN panels target at mainstream users and gamers. Moreover, TN panels provide the fastest response times and great in color accuracy and viewing angles. However, TN panels cannot satisfy the pro users. On the other hand, IPS panels offer very good color reproduction and viewing angles. However, IPS panels usually offer the response times that are slower than TN panels. Furthermore, IGZO panels offer better power and less mass which is ideal for use in high-density displays like a 4K monitor.

Moreover, refresh rates with 4K panels are also an important point to be concerned. Currently on the market, an affordable 4K display monitor offers 30Hz refresh rates. On the other hand, the typical refresh rate of a mainstream display is 60Hz. Furthermore, some gaming monitors offer as high as 144Hz. Although 30Hz is fast enough for editing videos and images. However, the user experience with a 30Hz display is not that great compared to 60Hz. Therofere, when using a 4K display with refresh rate 60Hz or higher display will gain more satisfying user experiences.

Connector Type

Nowadays most PCs drive 4K monitors successfully without any problems. For everyday tasks, such as editing photos or browsing web. On the other hand, driving 4 times the pixels in games , users will need powerful graphics card to have better image qualities. Therefore, for gamers will need to find some graphics cards that can corporate with 4K monitors.

The main hardware requirement for running a 4K display is that has a suitable output which will be compatible with a 4K monitor. Furthermore, HDMI can be used to drive 4K displays, but many of them (HDMI version 1.4) supports only at 30Hz on 4K monitor. With 30Hz the user experiences are not very pleasant. However, HDMI 2.0 supports 4K at 60Hz which provides the minimum refresh rate to run a 4K monitor. Moreover, DVI handles 2560 x 1440 at 60Hz easily, but not 3480 x 2160 (4K resolution). Therefore, users cannot drive 4K displays at 60Hz using DVI.

Operating Systems: Windows

Another major consideration with 4K displays is the version of Windows users’ computers are running. Furthermore, versions of Windows make differences as well. For instance, Windows 7 supports 4K displays, but not as great at handling scaling compared to Windows 8.1 and Windows 10.

Moreover, the smaller of the 4K screen, the higher scaling it will likely want to use. Windows is good at increasing size of fonts and graphics. Therefore, users can adjust the scaliging value easily to which is comfortable for users experiences.
