on bug 86320
from Morten Leikvoll
I should warn that some displays does not seem to follow the displayport standard properly. I would recommend trying a different one, and if its related to some models, discuss what to do. I dont have an answer for that. I am working on a embedded displayport source here and find a Dell U2913 2560x1080 monitor (It has a STDP9320-BB "Athena" displayport sink, with unknown firmware) does not report a correct SINK_STATUS (DPCD register 0x00205, bit 0) wich the specification says it should do. Also its seem to lock the LINK_STATUS_UPDATED bit to 1 (in DPCD register 0x00204) But even if this is wrong, it still shows an image. Googling my symptom made me find this thread. Wether to skip this test is a good idea is up for discussion. For an home/office environment, its probably ok, but for an industrial environment it may not be ok.
