--- Comment #9 from Samir Ibradžić sibradzic@gmail.com --- Created attachment 115742 --> https://bugs.freedesktop.org/attachment.cgi?id=115742&action=edit HB140FH1-401 datasheet
Finally got my hands on some p-coins (damn the neo-capitalist China!) and fetched the datasheet for my panel (or at least what i think i have inside my E455 according to EDID, but it seems right as several other Lenovo laptops comes with the same thing included). The timings looks the same as U38N, it is definitely 2 2.7Gbps lanes, but I can't claim i understand much besides that inside the datasheet. Yes, the panel is is full HD 1920x1080, here in Lenovo Japan it is available as an +$20 option, which was the main reason I bought this particular machine (besides the fact its AMD APU of course).
I can help debugging any patches or code hacks, so if you have any ideas, onegaishimasu.
