2 monitors side by side = flickering screen

[Yzzim]

Is it bad to put 2 monitors side by side? They're both CRT and when I turn 1 of them on, the other picture shakes like it's being turned on as well. I've seen people with 2 monitors before, but they don't seem to have a problem. What am I doing wrong? Why is my screen flickering on one of them?

I'm guessing it's a bad thing.... 😉

I have three monitors side by side and of course when you turn on one monitor while the other one is already on, it causes a pretty big interference in the monitor which is already on. No biggy, been doing that for over two years now.

If when both your monitors are on and you get interference in either one you can try to play with the refresh rates until it goes away.

try running the monitors at the exact same refresh rates, it that doesnt help, then there is probably minimal/no shielding on one or both of your monitors crt's. I tried putting an old 14 incher next to my 17, and had the same problem. It was so old though, that it would not run above 60hz! So I never did test out the 'same refresh rate' thing, I refuse to run my monitor at 60

ah, putting both monitors at 85hz seemed to have solved the problem. I thought I already had them at the same refresh rate, but the old KDS 19" was only at 75hz. I bumped it up to 85hz and now everything is fine 🙂

Guess I just wanted a confirmation that putting them side by side wouldn't ruin one or both of them.

Thanks 🙂

That is what is called "EMI" (Electro-Magnetic Interference.) Separate the monitors or place a grounded shielding between them. Good monitors have built in shielding.

NEC's and Nokia's have great big metal shields all around them. Heavy buggers, too.
