I purchased a Radeon 7000 AGP that was flashed for Mac on eBay. The posting said that it would definetly work in the G4 Cube. I want this card for TV Out. I removed the face bracket and put the card in. It is seated properly but I get no output. I've tried the VGA out, DVI out and even the composite video out. I get nothing. I plug the stock ATI Rage card in my Cube and I get a display. Did I get a bad card? Am I missing something? I've pulled and reinstalled it five times. Anything else I can try? TIA.
