HELP!!
I have Precision 7680 and shitty FHD 250nits screen... i bought (9Y5DM) 4k UHD screen and UHD cable..
should the uhd display work just plug and play or is there something to adjust with it. When the machine starts up, the red dell logo appears and disappears almost immediately. After that, nothing is displayed. The FHD display does work. I somehow believe that the cable is fine and the display works, but now there is some problem with the machine.. the bios has been reset, it doesn't help.. Both cables are connected to the machine /IR and EDP, which could be the problem, has anyone updated the display FHD -> UHD Touchscreen... Anyway, windows does recognize the display, intel UHD graphics.... help, my nerves are going...
I dont know where these cables must go??
I have changed video bios in my RTX4000 ada, to lenovo rtx4000ada video bios... can that couse that video signal is missing in my UHD OLED screen??
