Overview

Resolutions (ranked according to subjective preferability ;-P), plus jumper combinations for different LVDS modes :

  1. 1920x1200 (A+B+G for "2-6")
  2. 1920x1080 (A+C for "2-6", A+B for "1-8". A+C+G for "2-8")
  3. 1600x1200 (A+E+G for "1-8")
  4. 1680x1050 (A+D for "1-8", A+D+G for "2-6")
  5. 1600x900 (A+F+G for "1-8", B+G for "2-6")
  6. 1400x1050 (D+G for "2-6")
  7. 1440x900 (A+E for "1-8", C+G for "2-6")
  8. 1280x1024 (E+G for "2-8", A+F for "1-8")
  9. 1366x768 (B for "1-8", C for "2-6")
  10. 1280x800 (F+G for "2-6")
  11. 1024x768 (G for "6*2-1" (whatever that is), A+G for "2-8", E for "2-6", D for "1-8")
  12. 1024x600 (A for "2-6")
  13. 800x600 (F for "8-1")

Not all of the LVDS modes listed are actually correctly labeled - for instance, with 1280x800, it's listed as LVDS-2-6, but 1280x800 panels never actually seem to have a 2-6 connection, all of the panels I've encountered using 1-6 - and they're happily driven by the controller when using an 1-6 cable.

Firmware

Yep, I did dump it!
