    Thanks for your reply also. Now the refresh rate is staying after restarts I even increased it to 103hz. Those timings though, if someone can explain them in detail how they affect the display and how should they be changed with the increase in refresh rate will be very helpful. Currently I just use the default for my display so at 103hz I am at 238khz pixel clock which is the limiting factor to go higher (after 240khz resolutions stop to appear)
    So if I reduce some of the timings the clock drops but what effect this makes to the screen ? Also that sync polarity the default for me is +- with ++ works too. I found this explanations
    http://www.qnx.com/developers/docs/660/index.jsp?topic=/com.qnx.doc.screen.wfdcfg/topic/manual/cwfdcfg_timing.html
    it is for raster scanning displays though aka CRT monitors.

    How you do that? I'm so lost on how to do it on my laptop. I got same laptop with an gtx 970m.

    No it simply depends on what screen you're using. The 15.6" PLS displays overclock like champs ~100Hz. The IPS LG overclock like crap on the 15.6" screens. TN 15.6" also seem to overclock fine.

    I have a question I hope can get answered. This may be dumb to ask but I have a bay trail -M generation processor which I think is 3rd generation processor; is it unsafe to install one of the newer drivers like 15.40 or 15.45 etc. on it just to get a higher refresh rate on my monitor?

    Thanks in Advance.

    I have a hp pavilion ab031tx notebook. it comes with a 15.6inch 60hz CMN15C4 (TN) panel. I tried to increase the refresh rate with default clock, but even at 65hz artifacting occurs. I cant go anymore up than 62hz. does anyone know any custom settings by which I can increase it further?

    Read the first post lol

    I'm not so sure that's a reliable statement to make. My 15.6" IPS LG does 103hz ( ͡° ͜ʖ ͡°)

    You can try but I'm pretty sure it wont work. Bay trail uses ivy bridge gen graphics and driver support was always even worse. I've never been able to update the graphics driver on my bay trail t100 tablet so not going to try with this.

    It sounds to me like your panel doesn't like to be overclocked. Maybe try reduced timings in CRU and see if it helps? Or adjust some of the timing values randomly and see if it improves, otherwise 62hz may be all you can get. Don't forget to check for frameskipping too.

    It gives instant artifacting with reduced timing in CRU even at 60hz. No frameskipping seen at 62 hz though. But, i noticed that 62 hz is not completely stable, it runs fine but when i wake up my laptop from sleep sometimes shuttering occur for 1-2 seconds.

    Any chance this will work on an old Alienware M17xR3 3D panel with a 2720QM and a 680M? I'm already running at 120Hz but it would be interesting to see if it can hit the 144Hz mark on a laptop display. Any ideas?

    So, I'm having some issues here guys, hope I can get some help.

    Recently bought a Dell IS 7567 with i5 7300HQ (Kaby Lake) sided by a GTX 1050 and Intel Graphics 630.

    I tried to follow @margroloc steps but, funny, I'm stuck in the most basic stuff. I can't get the driver to be correctly installed (the BETA one, which's been tested). It says windows can't verify the driver's signature.

    Yes, I swear I installed it by using the .inf file as described in the post, but when I restart the laptop after installing it, I get this signature stuff message. Should I disable driver signature enforcing? Or maybe the driver ain't compatible with my laptop?

    My current driver gives me the option to try customized resolutions, but I get that "maximum bandwith exceeded error".

    To top it off, I think I'm not even handling CRU correctly. I follow all of OP steps but can't even get the new refresh rate to show in Intel Graphics control panel. I can confirm that I tried every possible combination from 63-75hz, switching between "Manual" and "Automatic - LCD reduced" settings, and could not do it.

    As an additional info, CRU names my panel as CMN15D2.

    Dont do it. Not worth wasting your time. I already tried it on CMN15C4 panel. The panel manufacturer is same for you and me. The highest i can get is 62hz from 60 hz. Even other posts confirm that the panel with 'CMN' as a manufacturer do not overclock so well. Two other person with same panel manufacturer were able to go up to 63hz only.
    As far as the driver issue, i clicked on the link posted by the margroloc. There,Intel promted me that a new latest driver is available released after this version.
    So, i downloaded that latest version and indtalled it using that inf file method. It asked to verify the installation as it is not digitally signed by Microsoft. I allowed the installation.
    After that CRU started working, i was able to add custom refresh rates.
    But the max overclock i was able to achieve was 62hz.
