Hello guys, i have an XPS 15 L502x with a cracked screen, so i have been using with an external display always on alwas connected. The thing is, i recently formatted my drive and installed windows from start, since then whenever i restart the pc, laptop display lights turn back on, even if the lid is closed all the way. It also stopped seeing the external display until windows loads, so i can't see the bios and startup screen on my external display anymore.
I would like to:
- Disable Intel HD 3000 integrated graphics if i can.
- Use Nvidia 540M for external display only
- Disable the laptop display completely and permanently.
- See BIOS on my external display
I have been using the external without changing any settings, i just connected the monitor, chose show on "Projector Only" on windows and it was fine. I saw the BIOS and all the info in my external no matter what. But now, whenever i restart, it switches back to laptop display, and when windows login screen shows up, it turns to the external, laptop display goes black but still backlights on almost as if i extended the desktop.
I tried disabling the laptop display in Device Manager, disabling the Intel HD 3000 in Device manager but nothing changed. Also tried removing the tick in Nvidia settings near laptop display, turning it back on. There must be something i can do about this. I installed latest Intel graphics driver and always keep my nvidia drivers up to date.
Last info, whenever UAC shows up on Windows, screen goes black once and then again like it goes black when changing monitors. But it happened way back when it was ok. I don't know if this means something but i would appriciate any help.
