    At least on my 95% NTSC display for my np8130(p151hm1).
    If you have a nvidia gpu at least, in the nvidia control panel you can create a custom resolution and custom refresh rate.

    Works for my laptop, and my friend's.
    I got my display to 95hz at 1920x1080. It's a lot smoother.
    Most noticeable in games like Quake Live.
    At 100hz, I get a few artifacts.
    At 120hz, all the colors are warped, but it's very smooth.
    One problem though, when I lower the brightness to minimum on grey backgrounds I get scan lines. If I go to 90hz, it disappears, but this isn't a big deal since it's only on low brightness.

    My friend could only do 90hz though before artifacts.


    It's not placebo, it's very apparent. It's not as good as my asus vg236h 120hz display, but it's much better than default 60hz.

    You should make a video comparing the screen refresh rate, I'm interested in this

    Yes indeed.

    A lot of LCD screens can survive this. But be careful not to break your LCD by doing this.

    I would suggest running a max of 75Hz if you have a 60Hz as default.

    Also playing some games at a extremely high refresh rate (above the default) may crash your GPU or screen at times.

    - good luck! :)

    I have two identical Samsung 19" monitors on my desktop; native 1360 x 768 (60hz) that have been running 1080p and 70hz for... around two years now. No problems at all.

    I don't have a high enough fps camera for that.

    Also to people who are claiming damage. I suppose it's possible, but considering i've ran 120hz on this panel for 10 minutes and no damage, I am pretty sure it's safe. (Though colors messed up at 120hz)

    Why would it crash my game or screen?

    It's been running perfectly for two weeks now. Also games run at the hz setting I pick automatically. I verified by putting vsync on and my fps drop to 95fps.

    The threshold of crashing is something you must test on your own, I don't really know any benchmarking programs for a screen, and I can't really imagine how it should work either. Therefore the only possible thing is to test one step at a time :)

    There are a TON of people that have discovered and asked questions and played with this on the internet, try searching on google: Let me GOOGLE that for you- LCD overclock

    They will probably run into limitations of single link dvi if you are at 1920x1080. Though 75hz is feasible.
    Most of the people discussing problems are talking about CRT monitors.

    also no need to use lmgtf


    I don't understand what you are talking about crashing.
    The desktop is running at 95hz already

    No offense, love using that website for some reason.

    Running my 85Hz (have been since 2010) no problems whatsoever, but do use it at your own risk.

    It would be interesting to get the manufacturing spec sheet of the monitor to see its true limitations.

    This any use? B156HW01 V.4

    Idk that they'd list a "max" refresh rate.. It's simply a screen designed to run at 60hz reliably so it's able to to run somewhat above that.

    It's most noticeable when you play a game and try the same sequence over and over again with 60Hz and 75Hz

    Also in some rare youtube videos, you see a noticeable movement when set on 1080p ;)

    I don't remember...what nvidia card do you have?
    Shall we push it further try to enable 100hz 3D on your screen with a little bios hack?
    You may need a 3D vision usb dongle though...hmm though I think I saw a virtual dongle somewhere, which we could use for testing before spending money on a 3D kit...if it works you would have 3D on internal 15' screen. ;)

    these problems are the DAC chip's limitations and not the LCD itself, I have 2x Envision P2271wL LCDs for the desktop and it weird, one can do 100hz no probs while the other struggles at 90hz yet they are the exact same models. I popped them open to see and the DACs aren't the same :(.

    Maybe I am doing something wrong here since mine won't work above 60...I'm right clicking desktop, opening Nvidia Control panel>Change Resolution>Custom Resolution> then keeping it at 1080p but changing the refresh rate. After that the screen either stays black (above 70hz) or is very distorted and can't see it (60-70hz). This is with a GTX 550TI and an Asus VE228 monitor

    Great thing you mentioned the monitor there.

    DELL usually has their monitors opened, while quite the few ASUS monitors are locked and cannot go beyond 60Hz :( (make sure you don't have vSync on)

    I have the 560m.

    I can do 100hz on the laptop monitor, but I get a few artifacts. I have a 3d vision dongle actually. Came with my vg236h asus 120hz monitor.

    I'm game for testing though.

    Thing is, at 100hz, wouldn't the glasses be flickering at 50hz? Sounds like eye destruction ;p

    Nvidia 3D works on 100hz 110Hz & 120Hz...100Hz actually flickers less if you are in a 50Hz country and have lightbulbs in your room...
    OK will prepare a bios mod and modded inf to fake monitor ID tomorrow. ;)

    It's not possible unless you've modded the driver... as far as I know (I'm pretty sure that is)

    But there's this application, it's quite old.. but see if it works: Download ATI Radeon RefreshRate Fix 0.9.9.7 Free - This handy utility let`s you set custom refresh rates for D3D and OpenGL. - Softpedia

    SOURCE: ATi Radeon refresh rate fix - Overclockers Forums (extremely old... but yeah, can't give you anything else :()

    just asked myth about the screens. they said that the screens dont refresh at a higher hz. I trust what they said, but if someone could please explain how this works I would greatly appriecaite it. Just want to know before i ruin my scree, dont want to damage it anymore considering i found a black dot not too long ago.

    ^^^Ingore... I just recieved an email today from myth. They told me that they had their R&D guy try it, and it works. But it will void your warranty. Glad to know myth cares enough to try, and to email me after without having to ask!!!

    Well it obviously won't work on all laptops. Internally the p151hm1 must have a dual link dvi cable and the controller can handle it.

    tried this, works great for a few minutes in gaming but after a while FPS will drop significantly.

    went back to 60 hz.

    nice thing to try though, 90 hz is really smooth.

    Nooby Screen Question :

    If I buy an external 100 or 120hz display and plug my P150EM in I can play games at 120hz right?

    Also say I get 60fps on BF3 1080p on 60hz display

    will that be the same "smoothness" as 30fps on 120hz display?

    Or is that not how it works?

    fps = frames per second whereas 60hz is the refresh rate of the screen...
    so if u have 30 fps and 120 hz display u will get a gameplay that isnt as smooth but of a sharper clarity... at least that what i think :p

    60hz is the rate that your monitor can refresh at so basically it can only show a maximum of 60fps, that's why turning on your vsync will limit your fps so that your screen won't tear. By that I mean a monitor that can't show above 60fps won't be able to maintain image stability, that's why people get 120hz for that smooth play. To be honest if your gpu can't go above 60 a 120hz monitor won't be that effective for gaming

    Maybe a stupid question, but would OCing your LCD cause any damage to it? Also, will it cause any stress on your card? Lower FPS?

    Overclocking your LCD would come with the obvious risk of over saturating your screen, burning out a pixel etc... but to be honest the chances shouldn't be high.

    It puts minimal stress on your GPU, but there's a slight, really slight chance that something might go wrong but do keep in mind that those who can be overclocked as we call it, support it so unless you go berserk with the Hz you should find something stable +/- 20~30Hz more ;)

    (THIS IS WHAT I KNOW OFF, I'm no professional :p)

    Hahaha

    Im super sorry for this ignorance, but what's the point of a higher refresh rate? I've read the thread, and all google gives me are HDTVs and don't fall for higher refresh rate.

    Explain in as simple in detail as you can.

    It's smoother, more natural. You may not notice flicker at 60Hz, but your mind does.

    Hmm, I guess I would have to play it to know a difference huh?

    This is so weird, considering I'm living my life thing 60Hz is the optimal refresh rate. Even doing a quick google would get me results of higher = bad. Maybe I'm not searching right.

    I've got mine on 75Hz, right about perfect and frame rates got up too, also youtube videos are smoother :cool:, especially Blu-ray movies! (some of them are locked @23 fps :()

    Just read my post, TL;DR A higher hertz shows more frames which equals to more fluidity when viewing. Absolutely no use if your GPU can't handle additional frames though

    I have a 650m 1gb drr5 and i'm using msi afterburner. even though gpu-z says my gpu clock is above stock, when i run a benchmark the core clock never goes above 835 MHz. any ideas? I can overclock the memory but not the gpu.

    So there is no good software to oc the refresh rate if I get the 7970m? I know it will handle many games above 60 fps . 60 isn't bad at all though I've even played bf3 at solid 40s and still always pwn. I'd just like the option to run at 75 or 80 for games like Diablo and other less demanding titles.

    I'll be trying the AMD/ATI refresh rate fix/hack that Juag1337 posted once I get the sweet system that's in my Sig. :p Hehehe. I want to run at 75/80. Seems like it would help a lot compared to 60hz ha.
