4K display or Ultra HD provides enough pixels to fill four full HD 1080p screens. Using a 4K screen is definitely better for editing photos, playing games and watching videos. In addition, if the number of pixels is four times, the display can display four times the level of detail. However, everything from the cable to the application you use will affect your experience with 4K displays.

4K resolution
First of all, what is a 4K display? 4K just means a clearer picture, it provides more pixels on the screen. Today, the industry has named the image as 1080p resolution and named it 4K after the image width. The pixels created by the 4K display are sharper and display more detail than standard HD displays. With a high-definition 1080p screen, the image only provides 1920 x 1080 resolution, while the 4K screen provides about 8 million pixels. On the other hand, it means that the user can set each pixel from 1080p to a quarter of a 4K screen. Therefore, the 4K resolution is twice that of the current 1080p device. 4K display
In addition, the native resolution of the 4K display is 3840 x 2160. In order to compare 4K with 1080p, all other conditions are the same, and the 4K display can produce sharper and more detailed images. In addition, when editing photos in a 4K display, it does not cause the photo to zoom. On the other hand, 4K displays provide unscaled images and benefit many creative professionals in the workplace. 

However, having all of the pixels in a 4K display can cause problems in some cases. For example, for an example, everyday computing tasks such as web browsing or paperwork typing are applicable to 4K displays. Also, for gamers, this will be a different story. Moreover, gamers need a powerful graphics card to achieve a playable frame rate of 4K resolution.

TAICENN always focus on high resolution display and industrial display system, such as industrial Panel PC and industrial monitor, for varies of industrial, automation applications.

LCD panel type
The current 4K display uses a range of different panel types. For example, TN (twisted nematic), IPS (in-plane switching) and IGZO (indium gallium zinc oxide) panel types. Next, the price ranged from the lowest price TN panel to the IPS panel and IGZO.
Typically, the TN panel is targeted at mainstream users and gamers. In addition, the TN panel provides the fastest response time and excellent color accuracy and viewing angle. However, the TN panel cannot meet the needs of professional users. On the other hand, the IPS panel provides very good color reproduction and viewing angle. However, IPS panels typically provide slower response times than TN panels. In addition, IGZO panels offer better power and lower quality, making them ideal for high-density displays such as 4K displays.
In addition, the refresh rate of the 4K panel is also a focus of attention. At present, the affordable 4K display provides a 30Hz refresh rate. On the other hand, the typical refresh rate of mainstream displays is 60 Hz. In addition, some game monitors offer up to 144Hz. Although 30Hz is fast enough, you can edit videos and images. However, the user experience of a 30 Hz display is not so good compared to 60 Hz. Therefore, when using a 4K display with a refresh rate of 60 Hz or higher, will result in a more satisfying user experience.

Connector type
Most PCs today successfully drive 4K displays without any problems. Suitable for everyday tasks such as editing photos or browsing the web. On the other hand, driving 4x pixels in the game, users will need a powerful graphics card to have better image quality. Therefore, for gamers, you need to find some graphics cards that can be used with 4K monitors.
The main hardware requirement for running a 4K display is to have a suitable output that is compatible with a 4K monitor. In addition, HDMI can be used to drive 4K displays, but many of them (HDMI version 1.4) only support 30Hz on 4K displays. With 30Hz, the user experience is not very enjoyable. However, HDMI 2.0 supports 60K at 4Hz, which provides the lowest refresh rate for running 4K displays. In addition, DVI can easily handle 2560 x 1440 at 60Hz, but cannot handle 3480 x 2160 (4K resolution). Therefore, the user cannot use the DVI to drive the 4K display at 60 Hz.

Operating system: Windows
Another major consideration for 4K displays is the version of the Windows user's computer that is running. In addition, there are differences in the version of Windows. For example, Windows 7 supports 4K display, but it does not work well with Windows 8.1 and Windows 10.

In addition, the smaller the 4K screen, it may want to use a higher zoom ratio. Windows is good at increasing the size of fonts and graphics. Therefore, the user can easily adjust the scaliging value that is comfortable for the user experience.
