Display Adapter or Monitor issue after replacing notebook screen

Hi all,

I've replaced my broken notebook screen a couple of days ago with the correspondent available model and since then I basically can't use it except when forcing Microsoft Basic Display Adapter driver to be installed instead of the latest version of the previously installed Intel UHD Graphics 620.

I'm an experienced user so I've disabled, uninstalled, reinstalled etc. all possible drivers and combinations but every time that this - I believe correct - driver is installed the screen goes black and I can only work with my external monitor (connected via HDMI).

I know the primary display is ON because it's detected on Advanced Display, but the resolution is wrongly detected and impossible (?) to change.

Important note: I had a BOE NV156FHM-N35 screen and I've replaced it with the same but more recent version BOE NV156FHM-N45, exactly same specs, connection type, etc. I thought it shouldn't be a problem.

Long story short, if using Microsoft Basic Display Adapter driver, the computer can't recognize anything else connected via HDMI, if using the latest Intel UHD Graphics 620 driver, the primary monitor doesn't show any image.

On the other hand I actually believe this may be also an issue related with the wrongly detected "Active Signal Resolution". Here's why:



...and also...



My screen should display 1920x1080 and that is never shown. Which leads me to this surely related issue which is the fact that the "Monitor" on Device Manager is constantly being reset to this:




Any helpful ideas? Thank you so much.

...no one? :)

well i doubt you would get a proper answer because the trend is when you replace any part you should replace it by exact model number when it comes to laptops or else hell break loose and this is your case .

If that model number isn't white listed in your laptop manual it probably should give hassles as bios sometimes step in and attempt to either apply certain parameter viable only for specific model number or at certain times choose to disable hardware for not being white listed .

so but why is it working when set to basic display adapter ? because that vga mode is global and standard within all screens the rest is a matter of give and take .

so is it a dead end , short answer yes , long answer is you can try to look in bios modding forums for help about the issue , which 50% you risk losing your laptop entirely and other 50% that you'd end up filling your laptop with viruses but i guess since you were adventurous enough to take that route you might well take that path

Cheers

I have also read all the answers on what appears to be your other MS thread.

The list of valid modes is contained in an INF file somewhere in the system a plain TXT file, so easy to read that.

On my Laptop it is listed as 'monitor.inf' however that is a massive list of Monitors/Panels and resolutions of those, somewhere in there must be what is correct for my Laptop panel.

'Generic PnP Monitor' is OK.
Properties for that. The INF name is in there, device IDs and so on.
That is all I know.
