This article provides information on text and icons appearing too small and other problems that are associated with using Ultra High Definition UHD 4K x 2K) and (UHD+ 5K x 3K) displays.
The newest Ultra-high-definition displays (UHD) are also called (4K x 2K) and Ultra-high definition plus (UHD+) displays are also called (5K x 3K) displays.
UHD displays have a nominal resolution of 3840 x 2160 pixels (double the resolution of 1920 x 1080) and UHD+ displays have a nominal resolution of 5120 x 2880 (2.6666 x 1920 x 1080 resolution).
Both UHD and UHD+ give incredibly clear and crisp resolution for movies and photo imagery.
As each new high definition display enters the market, there are issues associated with these displays that occur because of how the display appearance is modified when you change from a lower resolution to an ultra-high resolution display. Ultra-High Definition displays have 2 to 2.6666 times the pixels of standard resolution displays.
This gives incredible resolution detail on the screen but can cause images designed by fixed pixel amounts to display incredibly small and hard to see (these are known as Scaling issues). Images defined by screen percentage are not affected by the change to ultra-high resolution displays.
If there are a mix of scalable and non-scalable items in a document or HTML page, this can cause display relationship disparity of the items which may render normally on a 1920 x 1080 display. Microsoft Office 2013/365 is designed to scale, but if the size of the embedded image in a Word document is defined by pixels instead of percentage, the image will render smaller than expected in most cases.
The most prevalent issues reported with these displays are as follows:
In almost all circumstances, making adjustments in DPI and HTML scaling resolves image display issues.
Failures to display at expected resolution are often resolved with a combination of ensuring that the display is connected to the system in accordance with the user manual for the display, the elimination of cable adapters, and ensuring that the graphics adapter and graphics driver meet the minimum requirements for the UHD or UHD+ display.
Menus in third party applications may also display extremely small text. In many cases, the application itself may have scaling options in the program to allow the user to adjust the text size of the menus. One example is Adobe Photoshop (Figure 1):

Dell has no control over the scaling capability of third party applications (Adobe, Corel, Game Manufacturers etc.) and the technical support team for the application should be contacted for scailing issues in their products.
