Vista RGB Out Display Flicker

[Fluffball]

I found a RGB cord that connects the computer screen to the T.V. that I am using (An LG 42" LCD), after setting up the TV to receive the information correctly (using the instructions on the manual) the screen started flickering every couple of seconds. Sometimes the flickers are so rapid that I can't do anything, because the cursor seems to go to the middle of the screen each time it flickers. It makes a sound like the cord is being unplugged then plugged back in each time it flickers. The graphics card is a Radeon HD 3470 (PnP compatible). I set it to "Multiple Monitors (drag one window to the side of the screen and it goes to the other monitor). When I made the resolution the same on both monitors it worked a bit better, but after about a minute it started flickering again. For some reason it works perfectly on my Windows XP but flickers on the Vista.

Lower the monitor refresh rate?

Conflict of hardware? Have you check your system property in your control panel?

Thats what I thought, but I don't know what software is conflicting with whatever other software.

From your first explanation, I believe it's a hardware conflict, rather than software. To check it out, go to your control panel > system > hardware > device manager. Windows will list up your hardware and the ones with conflict will be marked with "!".
Do this with your LG TV connected and disconnected. This way you will have comparison. Then we'll go from there...

Will do the next time I have a chance (in about 2-4 days)

I don't think it is a hardware conflict because wouldn't that happen immediately, not a random amount of time before it starts happening?
