Recently my laptop screen had to be replaced due to a cracked screen. Original screen was a Samsung and the new screen is LG. After this, whenever I install Intel HD graphics, windows boots up till the login screen and then goes black, one bright flicker, then completely black again. However, when I boot into safe mode and replace Intel HD graphics driver with Standard VGA adapter, everything works fine, except for crappy graphics of course. I tried installing various old/new/latest versions of driver software, upgrade/downgrade BIOS, install monitor.inf file from lenovo website for this laptop model, everything.
Odd thing: running Dxdiag shows my current display to be 1200x800 (32bit)(1hz). So, I tried to change the display refresh rate in advanced settings> Screen refresh rate, no luck, no other option except ' Use hardware defaults'. So, I went ahead an modified registry values as given here: How to Modify the Video Refresh Frequency in the Registry.
Again, no use. After I reboot and go back and check, its set to 1 by default.
Tried 4 clean installs, installing on a completely new HDD, Windows 7 Pro, Windows 7 Ultimate, Windows 8 , everything.. Ubuntu works fine, no problems.
Is it a screen problem? Or some hardware ID kind of thing? What should I do ? Please help!
