    I have seen a number of threads regarding display flickering on the SP4 described as the display going on and off rapidly. I have not experienced that particular issue, but at 50% brightness and below occasionally my display will have that flickering appearance to it that you get when the display refresh rate is too low and you can discern the screen redraws. When it starts it will usually continue until I change Windows or turn the SP4 off and back on. Anyone else experience this?

    Do you have Hyper-V enabled? There is a known issue. You have to disable Hyper-V. No flickering for me since. You can try disabling auto dimming, but that hasn't created any flickering for me.

    I have disabled Hyper-V yet the issue remains. I suppose it could be the result of PWM dimming, but I only observe the low screen brightness flicker occasionally. If it was the result of PWM, I would think I would notice it consistently at low brightness levels.

    The firmware update does not fix the low brightness flickering. If I switch of the auto brightness and set the display brightness to more than 25%, then the flickering disappears. Otherwise it will flicker just very slightly and randomly. It is as if the backlight would be going to break - a little like an old light that flickers before it goes out. It is not the PWM flicker what I'm talking about. I think someone already measured that there is no PWM flicker.

    I know that mine seemed to go away by turning off the brightness auto-adjustment setting.

    I experienced this for a moment a couple days ago before yesterday's cumulative update on 11/24. I haven't seen it again since.

    Hi guys, I am a new owner of a SPRO4, and I am experiencing the same issue as the OP. I can see the thread is old, but I couldnt manage to find a solution.
    My device is fully updated.

    When i set brightness under 25%, my screen is flickering. It is really annoying, as I usually tend to read at night a lot.

    I tried
    - to disable Hyper-V
    - install the beta driver for the Intel Graphics 520 in order to acces HD Panel and disable the other options
    - reinstall the recomended drivers

    What would you recommend me to do? Complete reset of the device? Or ask my seller to replace it?
    Thanks guys!

    Edit : My SPRO4 is running perfectly, the only issue I have experienced is a black screen after I closed the cover on the running device.

    Welcome to the forum

    The flickering issue with brightness at <25% is a known issue and will likely see a patch soon. On the black screen issue, (they may be related to each other), several prople have foumnd using the Win+P keys 3 times or a ctrl-alt-del have brought the Surface back to life. That too will probably see a fix sooner rather than later.

    Thanks for your answer, I will wait for a future update and keep my device.

    So far I enjoy it so much, I was sad I'd have to return it!
