This looks like TMDSA load detection not working. Luc, can you look into this when you find the time?
Cheers, Egbert.
This happens depending on the monitor. Load detection is not part of the DDWG or whatever DVI specification, instead HPD and DDC are being depended on. So monitor manufacturers don't always try to put load on the digital lines. You will find that, when you run rhd_conntest, the monitor only at certain times puts loads on the digital lines. We have seen the same problem with some other monitors... So it is a problem with not the TMDSA load detection, but with the monitor attached to it, and a suitable strategy still needs to be proposed here. It would be a real shame to disable TMDSA load detection, but this seems the quickest solution.
