@potato FIXED: I updated my Intel VGA Driver for Windows 10 and now it works perfectly. If you have lenovo and have the same problem try to go on the lenovo support page, select your model and then download the newest driver. Worked for me :)

Please help

Update: the current dev version of flux (3.11) fixes the flickering issue! Just in time too, since school is just started back up. So now I can use flux on my main monitor! Sadly there still isn't support for USB adapters, but maybe one day... Thank you flux team for fixing this issue. This change will have a huge positive impact on my sleep/health/academic quality.

Hello guys, i come back with BIG News! I managed to fix this issue on my Lenovo y700. You have to go to Lenovo support page, select your device model and download the latest Intel HD VGA drivers. I had installed a version from 2015 and the latest was from 2016. Unpack the archive but do not run setup because it will fail. Now go to Device Manager, right-click on Intel HD and choose to upgrade drivers. Click: Browse My computer - Next - Let me pick from a list of device drivers on my computer - Click on Have Disk -> Browse and open the path where the drivers were unpacked (C:\drivers\Intel VGA Driver\Graphics) and select igdlh64.inf fro x64 OS or igdlh32.inf for X86 OS. After installation is completed reboot your computer once or twice. After the first reboot i had a problem with my desktop files missing but it might be due to other things i did to my system. If you encounter this issues just go to C:\windows\system32\config\systemprofile\ and create here a new folder called Desktop. Reboot and everything should be ok. PS: flux works great after this.

@cstation Yeah, keep it on Tegra for sure then, the compositor will most likely eat your battery.

Can you check for updates to your video driver? This is likely due to a driver problem so updating may help you.

I created an account just to reply to this topic, because I wanted to mention that expanding the range in the extras menu fixed the problem for me. I too ran into the flickering issue after installing a second monitor. Future help seekers, look here!
