Dell monitor suggested cable length
Video Cable Support on Dell Monitors: Dell Monitors are designed to work optimally with the video cables that are shipped with your monitor. The online monitor
User’s Guides will show you what cables ship in the monitor box when purchased New from Dell.
As Dell does not have control over the different cable suppliers in the market, or the type of material, connector, and process that is used to manufacture these cables, Dell does not guarantee video performance on cables that are not shipped with your Dell Monitor.
If you are using cables longer than 10 ft and signal integrity issues are encountered, it is advisable to purchase a repeater to boost the video signal. Dell does not recommend any specific brand.
The usages of all 3rd-party dongles are not tested by Dell and can cause video compatibility issues. There are Dell dongles with Dell part numbers that have been qualified by Dell.

- Dell PC Platforms and Graphics comply to industry certification standards.
- During Development, all Dell PC Platforms and Graphics are subjected to compatibility testing with Dell Docks, Dell Dongles and Dell Monitors/Video cables.
