Hi there,
I have been facing blank screen (turned on but only black with backlight display) after installing intel graphic driver on my Acer aspire VX15-591G, I have tried installing OEM driver, Older driver, Newer Driver, Clean Install windows, Clean Install the graphic driver (Using DDU Uninstaller), modding my Bios for the advanced & power tab (SPI-programmer+SOIC8 clipper, CH341a, HxD, UEFItool) , buying a USB HDMI to connect to my external monitor, and etc. yet the problem still persist... My laptop is usable and currently running on Microsoft Basic Display Adapter which make me unable to adjust the brightness of my laptop screen ( This is the main reason I want to fix it), can't connect to HDMI port, and I can't run anything on full screen (exclusive full screen) like it used to be (it's like 1-10FPS), I can run any game with borderless screen though. I have been searching for a month to find a method to fix this stupid driver problem, I have tried asking on Intel community forum (copy-paste reply/solution), Acer community forum (0 answer), yet none of those worked! and then while I'm still in limbo trying to find a fix, there is LTT forum on the list of google search, which make me wonder, why I haven't tried to ask LTT forum even though I have been subscribed to it's channel like 3 year's (I didn't know LTT have it's own forum).
So, Anyone can help to fix the problem here? at the very least I want to find a way to adjust the brightness of the screen without installing Intel Graphic Driver (It's really hurts my eyes since mostly I use my laptop indoor), I have tried doing it via registry editor (regedit) but it's seem it doesn't work. here is my system info:
Acer Aspire VX15 vx5-591g
Windows 10 Home 64Bit (10.0 Build 19041)
Bios Vers: V 1.08 OEM Bios (insydeh20) - (unlocked bios)
Intel i5-7300HQ - Intel HD graphic 630
Nvidia GTX 1050Ti (Mobile) 4GB
24GB DDR4 RAM
