Hello how are you guys?...its been a couple of days since i left this community but now its time i really need your help....i bought acer predator 17 laptop back in 2018 i did some upgrades to it.....it was working fine...but yesterday when i power on this machine every thing works except the display..it remains black no signal.....then i tried secondary monitor the display works but only through hdmi...the laptop’s display was still black....
The things i have tried so far were:
. Force shutdown
. Pin hole battery reset
. Open back case and clean the dust
. Unplug every drive and then reset battery
please suggest me some good tips except changing the panel cuz the country i lived in has not good quality panels.....thank you once again :)

    When you connect your PC to an external monitor can you check if it is seeing the display in Device Manager?

    Ok so that means it is seeing your monitor. Does it show any errors? (I'm not on PC so I forgot which tab is it but I think detailed.) You can see them by left clicking on your decidated monitor -> Properties.
  • Besides the tip from my mate @JohnCena, I found this:

    One thing to mention is that the display is coming from gtx 1070 and there is no option to switch the display to intel 620....do you think the gpu is causing the problem??
  • Is the hd 620 gpu not showing up in the device manager?

    No i think it was blocked after bios update...

    In most of the laptops screen is connected to HD graphics. Check if your model has dGPU.
  • What version of the bios was previously installed and which version you upgraded to. About the dgpu that my mate JohnCena referred to, it is an option in the bios that exists for some specific models. Check the bios and verify that hd620 appears as a hidden device in the device manager.

    @egydiocoelho i have previously posted a thread about this..there is no option to switch to dgpu cuz in acer has blocked it in bios update....my current.bios version is v1.13
  • OK! So correct me if I'm wrong. When you had a version before 1.13 of the bios installed, there was a function about dgpu in the bios, correct? Regarding my other question, does hd620 appear as a hidden device?
