My laptop come with the 720P non touch screen and I wish to upgrade to 1080p. But the existed LCD cable (DCXMF) does not support the 1080p edp connection, therefore I bought the edp cable (3PC10) from Dell and B156HAN01.2 display from online store.
After plug in the new LCD cable (3PC10) and the FHD display, the laptop cannot boot up properly and come out with 8 beeps alarm. I have run LCD BIST test by pressing button D + power button. The display can show the colour properly but it shut down after few runs.
I have run the preboot assessment as well. The system cannot detect the LCD cable and the display.
Anything I can do with this?
