Due to space constraints I have gotten rid of my desk and monitor and now hook up my PC to my TV. Its a Panasonic G15 plasma 50". The PC is running a 4870 1GB through a DVI to VGA converter and plugged into the PC port on the tv. The issue that I'm having is that if I try to change the resolution from the windows default (cant think of what it is at the moment) the screen goes completely black. This isn't an issue for normal windows usage but causes problems while gaming. What is causing this? Is it the VGA adapter? If I plug it in via HDMI would that fix the issue? Id have to order a DVI to HDMI which is why I haven't tried it yet. Any help would be appreciated.
