I just bought and unpacked my BenQ GL2450M screen, and can't seem to be able to make it work with my HDMI cable (I tested it on my TV and Blue Ray player, and it worked perfectly).
It works with a DVI-D cable though, so the screen is working fine aswell.
Isn't it just to plug in the HDMI to my GPU card and then to my screen? (Got a XFX Radeon HD 6870 1GB GDDR5.)
Any help would be lovly, I'm just an amature computer builder ^^
