Projector does display 1920x1080p fine from Windows PC and two KODI boxes. (And indicates “1080p” while Vero is booting, see video linked above.)
Took Vero 4K+ back to monitor and tried setting different refresh rates: 60 (default), 59, 50. None of them work on projector once OSMC has fully booted.
Looked through all video settings in Advanced mode and don’t see anything else to try…please help!
Tried two different HDMI cables - both work fine on monitor, neither on projector.
Thanks grahamh. I was hoping someone might have some quick answers if they’d seen this before. Here are the remaining Qs from that link:
Whether you can replicate this issue on demand. If you can, then please provide some steps on how an OSMC developer can reproduce the same issue.
Yes / Only occurs with my projector, but the projector does display 1920x1080p fine from Windows PC and two older KODI boxes.
The device you are currently running OSMC on
Vero 4K+
What peripherals are attached to the device?
Denon AVR & Infocus X10 projector
Has this issue been introduced by a new version of OSMC? When did the issue first appear and can you recall a time when it was not present?
No, new unit.
To answer bmillham’s question above, I did try the 4K+ directly connected to the projector, same issue.
It displays fine during first part of boot (projector indicates 720p) and the second part of boot (projector indicates 1080p). But once, fully booted, there is no display.
After turning on logging, the 4K+ was connected to the AVR/projector and booted at 20:02 ET, however, because it didn’t display after fully booting, I had to unplug it and take it to my monitor upstairs to upload logs.
I don’t actually see the boot time at the projector in the logs…is it possible the logs don’t get recorded if the power gets pulled?
I’m hoping you can see something here. Otherwise I will have to lug my huge monitor to the room where the projector is installed so I can switch cables on the 4K+ and upload logs without losing power.
I suggest you access your Vero via SSH while you are not having a picture and upload logs via grab-logs -A because only then we can see what modes are received in that moment.
In the current log we only see the values from your Benq Monitor which doesn’t help much.
Thanks for checking that in the logs. Yes. (Reported in the OP: I tried setting different refresh rates: 60 (default), 59.94, 50. They worked during boot, but not once the GUI had booted.)
GUI now displays on Projector through AVR. Thanks. Presume lower quality due to reduced color space, but that’s all my projector supports. What command should I enter to undo if I replace the projector in future?
Since nearly all source material is distributed as 4:2:0, there should be negligible difference between that converted to 4:4:4 and to 4:2:2.
Just unset the 422 setting. The ‘8bitnow’ doesn’t survive a re-boot.
For the record, the problem is Infocus have not understood the HDMI specification. They are advertising ‘deep color’ but the projector does not actually support it.
