I have a 9800GTX. Im running Vista Home Premium 32 bit. I purchased an HDMI to DVI cable to go from my rig to my TV, its a 50'' Panasonic Plasma. HDMI on the TV, DVI on the rig. I have both my monitor and TV hooked into the 9800. I go through Nvidias control panel to tell it to switch to the tv. I have to make the TV the primary if I want it to show up then change it back when I am done. Most of the time this works but sometimes it doesnt. It tries to show up but it eventually reverts back to my monitor. When it does work, I get tiny red lines through the screen periodically flashing around and sometimes it locks up the tv although the computer is still running. I have to unplug the tv from the rig and screw around till it shows back up on my monitor. Then it is hard if not impossible to get back to the tv. Sometimes a reboot will help. Usually not though. Why is this occuring? Anybody have any ideas? It is very inconsistent so its hard to narrow down why. Sometimes I can just plug in the TV by itself and it works and sometimes it wont show up. I am pulling out my hair!
