    Sweet, going to do it this weekend when I get around to it - exactly what I was asking for, thanks.

    Hi everyone,
    With Intel test driver "win64_154032.4568" I have success in applying 4K @ 50 Hz by defining a custom resolution with CVT-RB timing standard in Intel HD graphics control panel with following devices;


    Surface Pro 2, 4200U, 4400 HD graphics
    LG 43UH6100 4K, HDMI 2.0
    Plugable miniDP 1.2 to HDMI 2.0 active adapter
    Amazon Basics high speed cable.

    Not able to go beyond 50Hz though. Same 'maximum bandwidth reached' message.

    The difference between 30 Hz and 50 Hz is huge in terms of look and response.

    BREAKING NEWS (lol)

    Intel has posted the beta 15.45.4614 (21.20.16.4614) which finally appears to unlock custom refresh rates for 6th & 7th generation CPUs on Windows 7-10.

    I've tested this with a skylake laptop, hd530 with nvidia optimus enabled. Currently running the built in 60hz display at 65hz.

    Grab the driver here:
    https://downloadcenter.intel.com/download/26604/Intel-Graphics-Driver-Beta-15-45-#

    The built-in custom resolution tool still doesn't appear to work, but I used ToastyX's CRU to add the refresh rate and after a reboot it showed up in windows. Hopefully this works for you.

    Haswell CPUs are supported too with a different driver: https://communities.intel.com/thread/78158
    5th gen is still in the works apparently, but it seems they are finally fixing this problem.

    EDIT------------------------------------------
    60hz ---> 100hz, tested working. (damn son where'd ya find this)

    Seems there is a pixel clock limit around 1080p 105hz @ reduced timings, beyond which the custom resolution wont show up in windows - at least for me. 103hz showed up for me on reduced timings but it caused artificating and then everything above 60hz also started to artifact. Scary but somehow I fixed it and then got back up to 100hz, not going to try pushing it further. YMMV. What seemed to work for me is restarting the graphics driver after using CRU and then rebooting. Without restarting the graphics driver before rebooting I got flickering. Weird.

    Screen is a LGD04B9, 1080p, 6bit, internal displayport. inspiron 7559

    2nd and 3rd gen Intel CPU's are EOL so no updates for them.

    Thanks Intel, for nothing.

    So an update on this, as I know a lot of people from this thread didn't follow the new one.

    I figured out a workaround for 3rd gen Intel CPU's, not sure if this works on 2nd gen, but feedback would be appreciated.

    Hey guys,

    Much appreciate any help I can get. I have an Intel 5500 graphics chipset on my laptop and trying to hook up my a 4k monitor @ 60Hz. AFAIK, the Intel 5500 is a 5th generation CPU, and according to what I've read on page 6 in this thread, the test drivers should support custom resolution using CRU.

    I've tried uninstalling and re-installing the test driver posted in the following link, but I'm still not able to achieve anything greater than 34Hz at 4K resolution using CRU V1.3:
    https://downloadcenter.intel.com/download/26504/Intel-Graphics-Test-Driver

    Unfortunately, the specs on my laptop (Lenovo Edge 80k9 model) doesn't say whether the HDMI port is version 2.0 or not. Still, the laptop is like a year old, so I can't imagine the HDMI port is that dated!
