I have a trouble with the Intel(R) UHD Graphics 620 in my ASUS Vivobook of S410UQ-EB105T. In some screen colors, the screen has obviously flickering. This doesn't change with charge cable plugged in or not. This flickering problem distracts my care and I cannot take myself from looking into that parts having flickering issue. When I deactivate the Intel Graphics 620, there isn't any flickering problem. Maybe I can continue using this laptop by deactivating Intel graphics foreverly, but some functions of "fn+F5-F6" being screen constrast setting and wireless connection to TV don't work. Maybe there are other effects can also occur while deactivating Intel Graphics. Anyway, I read some suggestions in this platform that I applied, but they weren't a cure. Some of things that I made to solve this problem are:
1. I removed and deleted both intel 620 Graphics and Intel Sound Card from device manager, then I installed new driver from Intel.
2. I removed and deleted both intel 620 Graphics and Intel Sound Card from device manager, then I installed the suggested driver from ASUS web site.
3. I searched a new way to use Nvidia instead of Intel. I can't find how it is done.
Anyway, none of them didn't work.
Thank you for your help from now on.
You MUST use the drivers from Asus for your laptop, especially since you have dual (internal and discrete) graphics. The drivers for those graphics are modified to provide the proper switching between them. The generic drivers on the intel site are not modified.
So, make certain that BOTH the intel and nvidia graphics drivers are the latest from Asus.
