so i happened upon this review/thread of my new Samsung PLS and it suggests o/c ing the monitor to 72hz, here is the article http://wecravegamestoo.com/forums/m...review-matte-1080p-ad-pls-72hz-overclock.html (scroll down to overlcocking link and click ).

Im wondering if it is worth it as i have a Nvidia gfx card and the thread says this:

After downloading the latest Nvidia Drivers, Nvidia Users should follow the instructions in the above image to overclock the Samsung S24D590PL.

To force 72hz in games and OC download CRU from here and follow the instructions in this thread.

72hz is idea for movies and higher overclocks like 75hz mess up the colors. Overclocking the monitor also bypasses the Nvidia signal issue.


Any help/guidance is appreciated :)

:twitch: higher refresh rates don't only give moar epeen but are a lot smoother?

However, I'm not really sure on what noticeable difference going from 60 -> 72hz would make.



@OP: You should be able to make a custom profile to make it run 72hz @ 1080. Just look in nVidia Control Panel -> Display -> Customise and set it up accordingly.

If it doesnt work, it should auto-revert back to the previous settings that were fine.

I found that on my Dell S2340Ms that increasing the refresh rate is possible up to ~75Hz but the problem is the if feels like the display is dropping frames so it really results in a less smooth image. All in all, for my displays it wasn't really worth it.

Tried this on my viewsonic and anything beyond 60 made me reduce from 1080. And if I oversampled 2560x1440 (I think) it made me reduce back down to 58 hz. In games that supported higher resolutions it looked some nice allowing me to almost drop AA on a 1080 screen. Overall for me it really wasn't worth it. Some monitors are better at accepting overclocking than others thou.
Edit: I should mention I am using DVI. Word is hdmi or displayport work better for holding the signals.

Have a backup or dual monitor in case something goes wrong. which will happen usually with cru.

Things might work with oc/hz increase,but when you reboot might load to a black screen.

I been using CRU for years you people live under a rock :roll:
never had a issue with CRU causing black screen on most monitors it will simply display "signal out of range" and then fall back to the default so long as you don't set the refrash rate on boot without testing it first you are fine
just make sure you are using the "detailed resolutions field" and that that default refresh rate is first on the list

well it made a huge difference in the CRT days. if your monitor can do higher than it allows you, definitely try it.

Upping refresh rate TO 75Hz on my ol Nec Multisync LCD 1700V allowed better picture quality.

My old LG 24' lcd screen"overclocked" from 60Hz to 75Hz. The difference was noticeable when playing. A lot smoother experience even with so little increase. So i say it is worth trying :)

is it just me or is 60fps far too slow for a fps? anything less than 90 for me looks laggy even with a 60hz screen.

60fps is enough for me. But if it goes below that, then it's not good.

As I've mentioned a few times, I tinkered with this quite a bit. It allowed me to get my tv to 77mhz while using lcd overdrive (in catalyst). In my opinion, the results were tangible and worth doing. That said, at that point it was a really weird game of amd's drivers vs. ToastyX working around them (not to mention the video encoding/decoding issues as well as hdmi vs dvi drawbacks). At some point I gave up because eff it, but I think for many people it can be helpful.

That alllll said, I'mma just buy a P series tv 'cause it says 120hz input ('high velocity mode') on the freakin' tin (ie there *should* be a 1080p 120hz EDID). That makes life so much easier. In many peoples' cases...if you're truly thinking of doing this, imho just buy a 120hz monitor and be done with it...the advantages of 120hz (be it 24/30hz multiples for video/film, gaming smoothness, input lag, etc) are worth it.

That could be an issue with particular games where user input is directly tied to the same thread that handles rendering. That would make it feel rough with respect to you interacting with the game and at higher frame rates, it polls HIDs faster giving a smoother experience. This isn't true for games that are well designed and other than that, there is no reason why 90FPS would be better than 60FPS on a 60Hz screen, even more so since frames just get dropped otherwise.

With that said, a well coded game should feel the same at 60FPS or 120FPS on a 60Hz screen.

Got my Qnix 27" 2560x1440 @ 110hz. Been running that for the past 9 months. No issues.

I came from a 24" 1080p 120hz TN panel. The 10hz difference is not really noticeable, but the IPS (or PLS?) is certainly nicer.

Waiting for some 4k panels that are less than 40" and can do 120hz @1080p without fiddling with CRU.

I recently just purchased a 144hz monitor. Running at 100hz, 120hz, or 144hz, I do not not see much gain over 60hz. Natural selection 2 which I play quite a bit has incredibly fast movement where more hz actually makes a difference. Faster hz makes a difference but it wasn't anything impressive to me. Using lightboost, even on AMD gpu's, makes NS2 seem like slow motion because I don't lose my target. I feel like I am advertising but my point is that hz alone doesn't make a huge difference in my opinion. 60 to 72 just doesn't seem worth it.

Just for the record, it's worth noting that 72Hz is an interest refresh rate for a very good reason and I would like to explain it. Many HD videos in the USA have a frame rate of 24 frames per second of progressively scanned frames by ATSC standard, which is exactly 1/3 of 72 frames per second. As a result, you can render all frames of a video (1 video frame to 3 display refresh frames,) without dropping any frames or having to do anything special when the rates don't match up. So playback might feel less jittery as a result. Much like how video at 29.97 FPS (NTSC) would be less choppy at 60Hz because it's (practically) a multiple of the video frame rate.

So basically, when your refresh rate is above 60Hz and is a multiple of your video frame rate. You win. :p

The only monitor that does not seem to drop frames when overclocked are the X-Star Korean panels. There was a lot of talk about the idea behind dropped frames as a result in a Korean Monitor Owners thread at OCN.

60 to 75 is huge. (My monitor does both at stock) However, as someone else said they might not display all the frames when overclocked.

Have been using 120hz monitor for years, I'm not going back to 60hz forever.
