Operating Video in 75hz instead of 60hz???

Is it fine?

My video on this new SFF system is kinda weird. When is 800x600 res its fine. but if I switch to 1024x768 then its gotta be in 75hz. Otherwise I see a "wave-like" movement in my graphics.

Never seen this before and was just wondering if Operating in 75hz is okay.
 
not sure what is rated at. I don't have the manual ( probably printer on back of LCD though)

Its a Dell 17" E171Fp LCD. I have the "Hide modes this monitor cannot display" box checked.

So if I switch to 75hz then I should be fine right? No chance of damage?

Link to my LCD.
 
Sounds like some kind of interference. The severity would depend on how synchronous it is with your refresh rate, probably why it is better at 75hz rather than 60 hz.

I can't stand anything below 85hz.

Yea I just hate to damage and expensive LCD. But I just switched it to 75hz which was the highest available.

only 60 70 and 75 were my options.

Now no wave-like movement though!

but when running 800x600 @ 60hz there is no problem. So I don't see why there would be at 1024x768 @ 60hz. But oh well. I switched to 75hz. Hopefully thats fine. Otherwise there goes $350 down the drain!
 
Are you using fluorescent lighting?

Fluorescent lights flickers at line frequency and it might be interecting with your screen to cause the said effect.

If you're posting on said monitor running at 75hz, then it is OK... lol

What kind of monitor do you have?

I have a sh!tty old 15", and I run 1024x768 @ 85hz.
 
If it's an LCD, shouldn't you be running it at it's native resolution?

According to that link you have, it says the native resolution is 1280x1024. Try that instead of those other resolutions.
