I have just connected my HDTV (Samsung LE40A686M1FXXU) to my PC (In different rooms) via a 15m HDMI cable and a DVI to HDMI dongle and the picture is excellent except for anything that is black. I have thin red lines going through it.
Could someone help me to get rid of this please?
My PC spec is
Asus P5KC
E2200 2.2Ghz
2 x HIS 3870 (cross fired)
8Gb memory
