I heard about monitor overclocking quite a while ago, but dismissed due to my belief that 60 hz was fine. Now, I'm deciding to look into more since I'll soon have a second HD 7950 for crossfire which should be able to push well over 60 fps in many games.
Currently, I have a 1080p Hanns G monitor that runs at 60 hz and I believe to be a TN panel. I assume that it is worth it to overclock a monitor assuming the graphics card(s) can push that many frames per second, but if I could get some individuals' personal opinions on it that would be great. Also, how much risk is involved? While it would be nice to maintain higher refresh rates, I'd also ideally like to know if I should be prepared to purchase a new monitor before overclocking. Also, assuming it is TN, is it more likely to be able to reach high refresh rates than an IPS panel? I'm not sure, since I would think it would since the 120/144 hz monitors all seem to be TN, but then I hear about some Korean IPS panels being able to reach 100+ hz.
Also, since I'm using AMD cards, I believe that monitor overclocking isn't built into the drivers and I need to use something like CRU (Custom Resolution Utility) to overclock.
Thanks for any help.
It's not a graphics card task to deal with refresh rate nor the monitor's to deal with frames per second as far as I know.
I wouldn't trust a no-name korean IPS pannel to arrive with no problems.
If you really want 120hz or 144hz get a benq xl2411t or ASUS VG278HE, the only decent LCD pannels for serious gaming at the moment.
I'm not looking at getting those refresh rates, but I am thinking about trying to overclock into the 80hz range. And it's very doable with nVidia's drivers and third party applications. Also I believe some Teksyndicate have overclocked their own monitors. I'm mostly just worried about the risks in doing so and how likely it would be to damage my monitor.
Here's a video from Linus on it, athough he doesn't go into detail on the risks.
Just a quick side note: How do you embed youtube videos? I seem to have sort have accomplished it with the tool for embedding images, but it doesn't seem to be perfect.
Overclocking your monitor refresh rate -(4 AMD users)
hanns g monitors are capable of upto 75Hz in analog mode (i own one) so theoretically uping it to 75-80 maybe possible in digital but oc'ing monitors isent realy a good idea.
You will be better off selling it and grabing a 120hz monitor.

Well to be honest my monitor already has some weird problem where all sorts of red pixels appear from time to time when the backlight completely turns off and back on (either due to a game going fullscreen, or the monitor being turned off and back on) so I doubt I'd actually be able to make much off of it.
I decided to try it just to see what I could get, I managed to get 70 Hz to work pretty well it seems. I didn't notice anything unusual with the picture my monitor output, and there wasn't any frame skipping. That said, when I tried 75 hz my monitor wouldn't accept it at all. I don't feel like taking the time to fine tune it. I might mess around with 70 hz some more, but it's not that big of a difference over 60, so I'm just leaving it at the default 60 for now.
One thing I really don't like about 120 Hz monitors is the price. They usually seem to be in $250+ range (unless there are some cheaper ones I'm missing), and at that point I'd much rather just spend a bit more and get a Korean 1440p IPS since I'd prefer the higher resolution over the higher refresh rate, at least in my opinion.
Overclokcing the monitor never works well. the problem is that while you may hit 75-80Hz on your 60Hz panel, many full screen games will only offer the native refresh rate of the panel, and thus once you launch it, it drops right back down to 60Hz. furthermore if you use multiple monitors, the refresh rate switch will often cause video playing on the second display to temporarily lose hardware acceleration (thus making the video turn black (or with players like VLC, it will case them to crash), (this often also prevents alt tabbing to fix because it causes a refresh rate switch each time.
Overall if you overclock the monitor, you will often not be able to use the higher rate while gaming.
here is Database, Please post your results here too
and Radeon Pro on AMD card resolves the issue you said "on your 60Hz panel, many full screen games will only offer the native refresh rate of the panel, and thus once you launch it, it drops right back down to 60Hz. " NOT ANY MORE as RADEON PRO solves the issue by settind Dynamic refreshrate and make it 75 and it says 75 for example...

Here is my mission to create database for monitor overclocking info, you see ur monitor and see tha some one made it run 80hz from 60 so you can happily try that,
or if 65 is max, youl know to stop on 65.( English is not my main language) But i try my best.
Happy Ocing
