Monitor ran fine with 75Hz, Now with new computer the picture gets :(

Hi.. Sorry for weid title but i could fit funny there so i put a sad face instead.
So on my last computer with nvidia gt 430 gpu i oc'd my monitor to 75Hz (Freaking loved that speed)
Now with the gtx 660 when i oc the exact same monitor to 75Hz the picture gets messed up and the resolotion gets completely out of the normal. i did set the pixel ratio to 1600x900 that is the stock one..
Is there a colour setting on the monitor i have to fix or is it another thing?
If i way worse gpu can handle it so should a gtx 660 i feel...

Hey mate,

First, check the box that says 'hide modes that this monitor cannot display'. Is 75 still listed? If it is, let me know.

Oh no im using custom resolution setting and the evga monitor overclocker tool, becouse if i did what you said it would only go with 60hz I managed to get the monitor to 68hz (my secondary monitor) and my main Dvi monitor to 66Hz, i think though that getting a dual link dvi coord will help me get to atleast 70hz. becouse i care the most with my main monitor becouse its the one i work and play on the most obviously

I think I found your problem.

Unfortunately, I am no expert in customizations and overclocking, so someone else my have to input here.

ok. and my prob was? also, the thing that happens with the monitor at that refresh rate is that the reslolution gets messed up

You should really be running it at 60 Hz

It should be 60Hz, no more, no less. Is the picture is fuzzy at 60Hz, you have some other problem such as not adjusting the monitor to its native resolution.

LCD monitors ain't as forgiving and the old CRT ones were.

If its an LCD monitor refresh rate does not matter, they don't refresh like a CRT does. The LED's are either on or off, they don't "refresh". Leave it at 60 HZ if that's what the manual says. Increasing it will have no effect on the picture quality. You should also be running it at the native resolution. Anything else is going to degrade the picture quality. The image on a CRT monitor has to be constantly refreshed by the electron beam in the CRT. At low refresh rates it can cause flicker and give you a head ache. LCD's monitors do not flicker like CRT's do. IMHO there is absolutely no point in trying to overclock an LCD monitor. There really isn't anything to be gained by doing it.

okey. i have seen what you have said. i have been running my old monitor a long time with about 70Hz
And now im running both monitors with 66Hz. I just need to say that Sure 60Hz is nice but having the monitors at 66Hz does a ton of difference. Sure the mouse and windows does move smoother but bearly noticable so its just in the margin or error. but after long periods of sitting in front of the monitor you just feel a lot more eased eye and brainwise. even that small increase is such an ease on you. quite interesting. though the picture quality is exactly as good.. also quite interesting, Though if im running 6Hz faster than the monitors are "made" for. What dangers could this cause? I have only seen that extreme oc may just burn the monitor but 75Hz is not anything risky at all, so 66Hz would not decrease lifetime and increase heat by very much at all
