I have hd Lcd 22 inch samsung. When i connect my lcd tv with my pc graphic card it was working fine. But after 6 months my hd tv created problem. It automaticaly keeps on changing channels and volume even if I remove hdmi port from my lcd. I checked lcd tv remote but it was fine.
I had same problem with my hd lcd tv 42 inch philips a year ago. No idea what is the problem. Is my graphic card creating problem. I havent changed it yet.
My graphic card is NVIDIA GeForce 9800 GT.
