Hello Piotr,
Could you check if the projector has a newer firmware and update it?
Also, what is the resolution and frequency that your projector supports?
Did you have the opportunity to test with other HW configurations (a monitor
instead projector, new HDMI, just to be sure a different computer connected to
the projector, etc)?
Could you attach new dmesg with drm.debug=0xe with the latest kernel?
And once provided the information, please change as REOPEN :)
Thank you.</pre>
