    Screen starts to flicker after logging in for a while


    Hello

    This is an entirely new issue. My screen starts to flicker after logging in/turning on computer for a while, and/or if I launch an app that uses my Nvidia card (my laptop has Optimus), I'm not exactly sure which of these two causes it. For the first while after a restart, the screen appears fine. The flickering appears on desktop background + internet browser as well, so I'm pretty sure it's not a program compatibility issue. The flickering is not severe (the type that looks like horizontal bars sliding up) but it's an annoyance.

    Tried:

    • Disabling Windows error reporting + problem reporting service in msconfig
    • Restart computer
    • Resetting Nvidia global settings to default in Nvidia control panel
    • Checking for display drive updates in device manager (all up to date)
    • Checking monitor refresh rate (60Hz, can't be changed)


    Laptop I'm using:

    • i7-4700MQ 2.4GHz
    • 1900x1080
    • Intel HD 4600 + Nvidia GT750M


    Thanks for suggestions.

    Seems I can't edit posts...

    Anyway I noticed that if I leave laptop idle for a while, or go for a few hours without using graphic-intensive programs like games, the flickering weakens and eventually stops. If I play a game, within minutes the flickering would come back (gradually).

    Do you have Hyper-V enabled? It causes my screen to do that when it is enabled on my laptop.
    It's a well known issue.

    I don't really know what Hyper V is, upon googling it it seems to be only for Win 10 professional? So I wouldn't have it as I'm running Win 10 home.

    Just checked in Windows Features, nope I don't have it.

    Something else you may try is to disable "Intel Virtualization" in your bios since you are running W10 home version. That got rid of the last of the small screen glitch on my Asus Q534UX notebook.
