Hello!
I've two monitor connected to my PC.
My problem is: the bigger monitor has a line that goes up and down. I think
the smaller (and older) monitor generate electromagnetic interferences that
cause that line.
What could i do? Shoul i change the refresh rate?
Any idea?

yes you can change refresh rates and see if that does the trick...
But I would not suggest you go under 85 Hz

You can also increase the distance between them

A piece of sheet metal placed between the two will stop interference. More

I used the side of a discarded tower case, big improvement but not
perfect. Then I grounded the sheet of metal - now it's perfect :-)

Yes, running the 2 at different refresh rates should help.

Thank you so much everybody.
I'll try.
I've set the refresh rate to 120 hz but no difference! I think it didn't do
it... (i've the newest driver for my video card)

Thank you
