I have an older dell machine that I just installed a new PowerColor ATI Radeon HD4350 PCI video card in. I wanted to be able to show pictures from the computer onto a Samsung TV via the HDMI cable. The issue is that I am not getting any video. If I plug a monitor in VGA or DVI I will get the Dell splash screen and then nothing...when I plug the TV in I get nothing...no video input. I can plug the VGA cable into the onboard card and it works fine and when I check device manager I don't see anything wrong with the card. It shows fine in the list. Any suggestions?
