im trying to hook up my dell optiplex 755 to my tv (no dvi/vga). im using an s-video to rca adapter, and i have everything wired up correctly. however, im not getting any signal on the tv. my card is a radeon HD 2400 XT and i have tried this with both ubuntu 10.04 and win xp pro.
i think the problem is in either the adapter or bios, because im not seeing the bios on the screen but i do get a beep from grub2. can anybody help me fix this?
i didnt end up trying the vga to rca cable, but i did get it working. i think the adapter i was using was backwards, i.e., it was rca in to s-video out. i did end up using a standard 4 pin s-video cable and plugging it into my dvd player (didnt realize it had a s-video port) and it works fine
