I have radeon HD4870. it connected to my tv with dvi>hdmi adapter (my tv doesnt have dvi input). before a year ago it stopped working. the tv doesnt recognize my pc and since then im working with dvi to vga adapter.. because with the vga cable it works.
i checked the graphic card on other computers, on other TVs, using with other cables and adapters. doesnt working...
i also checked the card with a pc screen with dvi cable and its working
