HDMI not recognized on graphic card
I have recently installed a new graphics card Radeon HD 4350 as I wanted to have dual monitors from my PC. When I installed it I found that the DVI connection worked fine but when I plugged in the HDMI the screen went black. I thought I must have mucked up the installation or there may be some more up to date drivers. Went to the AMD website and downloaded the recommended driver. Unistalled the previous driver and rebooted the PC. Installed the new driver and had the same result. When I unplug the HDMI connection I get the desktop. I have also downloaded the HDMI_R261 driver from Realtek thinking that it may be that but it has made no difference. The monitor has a VGA input and that works fine and the HDMI cable works OK on my mate's laptop so I'm satified that it's not the cable or the monitor. I have to add that it was all working fine before I upgraded to Windows 7 before that I had Windows Vista and a Radeon HD 3400 graphics card. I did try to reinstall that but still it is not recognizing the HDMI. Has anyone had an experience like this? Were you able to fix it? If so can you tell me how please.
