Television as secondary display

[Elurew]

hey all.
i have been looking into getting the marvel g400 for a few months now. Anyhoo, today i bought a tv to hook up as my secondary display. My current video card is the crummy ati all-in-wonder pro. However, when i turn my tv on when my monitor is on, i get these horizontal lines scrolling up or down the screen. I remember reading something when i got the card about ferrite shielding protecting the monitor from various crap like tv's. Anyway, if anyone could elaborate more on this that would be great.
In addition, does the g400 have this problem at all? If it does, what could i do to prevent it. If not, what does it do to prevent it.
The lines really aren't that much of a bother, but it'd be nice if it could be fixed. Thanks a lot people.

It doesn't have to be your ATI that is subject to interference, most monitors are susceptible to it as well. While testing another PC a few weeks back I had to put the "new" monitor on a shelf a few inches above my regular monitor which got quite upset ! Since both monitors were at least 2 feet from either of the PC cases, I don't think that the video cards were the problem.

I do not think it is anything to do with the PC. The PC monitor and TV are running at different line and field rates and the rf fields generated by them interfere with each other. This is annoying but normal.

Move the monitor and TV apart to stop them interfering with each other.

Experienced the same thing...

Only solution i found is to separatetv and monitor...

My NTSC monitor is 3 feet away from my Computer monitor... and my TV is 3 feet away in the opposite direction...
