--- Comment #3 from Maximilian Böhm winlux@gmail.com --- @Alex: Sadly, its not working, not at all. It's horribly broken since at least Linux 4.0, 3.18 still works. I have a Radeon HD 7770. Just tested with Linux 4.3 RC7 and it's still broken. Finally, I've found this report! It has driven me crazy over the last months. Dozens of hours flowed into my HDMI experiments with different monitors, AV Receivers, cables and boot parameters. Please fix this mess as soon as possible!
There was this regression/patch that aimed to fix it but failed with it: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2d...
