Overclocking Monitors Refresh Rate

post #1 of 6
Thread Starter 
Hello Guys,

As some of you might know its apparently possible to ''Overclock'' the refresh rate of your monitor.

I have used the Custom Resolution Utility that i found here:
http://linustechtips.com/main/topic/31526-overclocking-your-monitor-refresh-rate-amd-gpus/

So i made a new profile on 1920x1080p with a refresh rate of 70hz, i dont get no blurry image or black bars at the screen like other people experience when setting a too high refresh rate.

I even played some BF4 with vsync enabled and it was vcsynced on 70hz. Since 70hz seems to be working perfectly i now changed to 75hz. That seems to be working perfect as well.

Now i read about its possible a monitor is dropping frames inbetween to still get to the 75hz i set.

How can i actually test if this is happening?

I do found some software tool i forgot the name of, that has some black bars that alternate from white to black from left to right. It looks exactly the same on 60hz as 75hz.

Do you guys know a way to test if my monitor is actually showing 75 frames each second?

The monitor im using is a Samsung s24b370h 1080p 60hz.

edit:
I found the name of the tool to test if its supose to be working.

I remember seeing somewhere that depending on the monitor it may or may not increase your refresh rate and in some cases actually cause stuttering. Don't quote me on that though I just remember that off some random post, well one way to see is recording your monitor with a camera that records at 120fps or something then slowing it down tongue.gif.

Yea i geuss recording with a camera with a higher recording FPS then my Monitor Frequency would do the trick.

Too bad the only camera i have is on my phone, and i bet it only records on 24fps redface.gif

But i geuss its the only way, because the software on my PC doesnt know what my monitor actually displays.

This sounds interesting... never knew about this. Please continue...
Will this not damage a monitor in any way?

Ive read about the possibilty of shortening the lifespan of your monitor etc. But the bad thing is i have no way of testing if it is really working.

Perhaps if i set the refresh rate high enough, that it doesnt work then i atleast now my monitor is ''accepting' the signal.

Thing is when i set my monitor to 75hz, and enable Vsync in example BF4, it stays on 75fps instead of the normall 60fps.

And i really do have the feeling the image is way ''sharper'' when motions are on screen.

If you look in the links i posted in the first post there are many people who actualy get this to work.

Apprently most of the Korean 2560x1440 monitor users also use this method to up the hz/frequency of their monitor.

Hmm, although I've never seen anything about people monitors dying because they OC'ed it. Overclocking a monitor doesn't seem like a bad idea.
