View Full Version : Monitor Interference

November 24th, 2003, 23:55
I know of many people having side by side monitor setups using 2 video cards. Well in my case I want to have two computers running and I want the monitors side by side. The only problem is I am getting interference on my monitor (slow moving horizontal bar that scrolls down the screen, very light and hard to see but enough to be noticed). I have also received this interference when I have placed one of my video monitors by the computer monitor. Any help will be much appreciated.

Simple answer... but it might make you look like a Roswell believer...

<center>monitor -- 18" square of cardboard wrapped in foil -- monitor</center>

The foil wrapped cardboard will null the interference.

Sounds kookie but it works.

That is an answer I wasn't expecting. Reminds me of putting foil on the old t.v. antennae to get better reception before cable. I'll give it a shot. Thanks for the advice :)

it is your refresh rate
the same thing happened to me when i had a crappy video card for one and a good card for the other...i couldn't up the refresh on the crappy one, and i couldn't stand to look at the other one with the refresh turned down...

just make the refresh rates match and that should fix it

I'll make sure they are running at the same hertz. It's kinda common sense but I must have not been thinking straight. The video monitor I have though doesn't have an adjustment knob for the hertz so I might try the foil box for it.
