My friend has a first generation powermac G5 (bought in 2003), he just got a 20” WS LCD (Benq) and when he tries to run it at max resolution (1680x1050) he gets horizontal muti colored lines that run though the display, looks like video card artifacting, this does not happen if he goes to a lower res. This is using the DVI connecter, other than that he only has some proprietary connector on the card (ADC I think). I have the same LCD and have no issues, so we tried it on my PC and it was fine, I have an EVGA 7900GS video card. It seems that his video card is not up to par or defective, it is an ATI Radeon 9600 Pro with only 64MB memory (I can’t believe they would put a card this cheap in the G5). It also appears to be AGP, but the slots look a bit different than the AGP slots on a pc, if he wants to get a replacement card can he just get a regular AGP card, or does it need to be some special standard (2x, 4x ect)? We want to order a replacement on newegg but are not sure which one will work correctly. Thanks.
