We just installed a new Benq XL2411Z and when the screen should display a black background (as wallpaper), it splits into 2 parts black and red.
The problem is from the beginning .. and persists even after a reset of the screen.
The graphics card is a new EVGA GTX970 SSC ACX 2.0+ which works well on other screens.
We tried with a DVI or VGA cable: same problem
Thank you in advance for your help
