Hello Everyone! I have problem - black screen on the laptop monitor when I connect an external video card using exp gdc. The fans are spinning, video card is working, the keyboard is also working, but screen is black :( I tried to connect an external monitor, but it din't help. I also tried disabling the discrete and integrated video card in the bios. I used delays on EXP GDC like PTD, turned on ATX PW (the power supply of the unit and this station outside the laptop), the result is also zero :( Everything loads, works, but there is no picture
Do you have any ideas to solve the problem?
My laptop: Acer Aspire 5 A515-44g Ryzen 5 4500u
