Monitor frequencies

Recommended Posts

I've been trying to push my monitor a bit lately, and see what it can do.
I've been increasing the frequencies to very high numbers. I managed to get my LCD 17" to do 150Hz, more than double its usual frequency (60Hz).
Has anyone ever gone higher than that? Is it safe? What will my monitor do if I force it to do a frequency which it can't?

Thanks in advance.

I believe you should consider it unsafe if you exceed either your monitor's or graphiccard's limit set by the manufacturer.

Probably should, but my warranty isn't void until >150Hz!

If you go beyond the available frequency, you won't be able to see anything.  You will need to hook it up to something that can view it at that frequency to find the screen controls to reduce it.  I don't recommend pushing it anywhere close to that high.

The whole point of the frequency is to avoid screen flicker.  The human eye cannot notice the differences above something like 70Hz.  I'm not even sure it's that high.  Most monitors only go up to 85Hz, and that's even too high.  You're only going to burn the equipment out faster using refresh rates that high.
