Double Image On The Screen
Discussion
Extension cables, docking stations and longer cables may be prone to ghosting, lines, double images, or poor focus. The improper shielding of the extension cables will cause a shadowing or ghosting effect.
This improper shielding causes a mismatch of the input impedance between the video card, the video cable, and the monitor/projector.
If you need an adequate extension video cable, please contact Projector Repair World.

Using Low Quality Cable
In addition, if using a switch box or low quality cable, these two items will also cause signal degradation. Check the video cable to make sure all the pins are in good condition. Test the monitor on a different computer.
