Upgrading Lenovo Y480 screen from WXGA (1366X768 - HD) to FHD (1920x1080 - Full HD)

  • Confirmed that Y480 has single-channel LVDC from motherboard, Y580 had dual channel. Cannot just replace LCD with Full HD as its missing controller signals. Bummer.
  • Find compatible Full HD screen replacement
  • Find VGA-to-LVDS controller board to fit where DVD drive was located. Remove DVD drive and permanently fasten cover.
  • Find (slim) VGA cable to solder from motherboard to VGA controller board
  • How to turn off display when standby, etc?
  • How to adjust brightness via OS? If VGA output is used, backlight is off. sigh.
  • Processor has provisions for eDP and second channel LVDS but none are populated.

Thanks for reaching out!
In the end no, I did not follow through on this modification. I would have had to remove the CD-ROM drive to make space for the VGA-to-LVDS/eDP adapter probably. If the motherboard had the additional LVDS or eDP lanes populated then might have tried it out. Concluded that next laptop model should have Full HD to make it easier to upgrade (screen swap). I picked up a used Lenovo and replaced the LCD with a higher quality one in the end.
