Yeah if you have auto refresh rate turned off and the GUI set to 1080, when you play a 4k file it will output in 1080. You can check this by using the TV remote to click in the top left corner of the screen and then clicking where it comes up with ‘HDMI 1’ (or whatever input you have it on).
My TV set is a LG OLED65C7
I’ve just started to test this box and one issue I’ve realized is that the images seems a bit in the dark side. Clearly darker than they should. In 1080p and 4K HDR with the October firmware/update version.
I’ve done some comparison with my HTPC and the internal TV player. Obviously the same settings, black level, gamma, contrast, bright, etc…
At this moment I’ve got to solve the issue just increasing the bright in the Vero from 50% to 51%. Not sure why but it seems that at 50% it’s like some luminance “bit” is lost so forcing a non-default brightness just fix it. But, honestly, a bit lost and just guessing.
Last week was C8 firmware updated and subjectively I think it’s failing to play HDR more often. @sam_nazarko, is there a ETA for November/December Vero Update?
I’ll release an update shortly which should keep everyone’s devices working well over Christmas.
With auto refresh rate off you get 1080P with HDR if your UI is set to 1080P.
I have an LG C8 and had all these issues as well but they all went away when I changed the CEC/ARC settings.
From my experience I think it’s a CEC/ARC issue.
I can even get it to work with a cheap 10Gbps HDMI too.
Here’s what I got if it helps at all:
Dude, awesome! Thank you! This helped (tested several videos and OK!)
- Switch source to this device on startup Enabled
- Devices to power on/off were disabled, changed to TV
- Send “Inactive source” command on shutdown enabled
- Put devices in standby mode when activating the screensaver enabled
- wake devices when deactivating the screensaver enabled
Indeed, with those CEC settings it’s working! Tested it with several 4k HDR Movies and Auto Refresh Rate ON, all of them played without problems in Resolution switching/lost Signal… Thanks!
Tryed this, but it has no effect for me. Still going to no signal when playing the demo files mentioned in this thread.
Funny though. I have now tryed Haunting of Hill Hause 4k. Started out with no signal, pressed the back button on the vero remote. It returns to the menu but starts to play the file on the background or something. When I try to resume the video it goes back to no signal. So now I have a spooky episode playing and now way of stopping it
I guess there are multiple issues then. It’s great that we have Sam.
Still though, the CEC settings you mentioned are doing something at least. It can now play on the background
But the settings on itself a far from ideal. I dont want my TV shutting down when I watch some live tv not via the vero.
I’ll make a new thread with a number of improvements shortly; then we can check out the corner cases and get those solved.
I have now applied the hotfix and everything is working flawlessly again. Hoping for a permanent fix in the near future
Do you mean you don’t get banding when playing a 4k60hz video?
For the record, on the August release, the GUI and everything else was in 8-bit unless you forced 10bit with either the ‘HDR auto’ mode or with echo 10bit > attr.
On the October release, everything is played in 10-bit. This has exposed issues with some screens. I suspect they didn’t have issues before because they were playing in 8 bits. People might not notice unless they are watching pale skies like the ones in The World in HDR and Revenant.
If anyone has evidence otherwise, we need to address that.
Sorry, ill be clear. Eveything is playing again. Received the vero recently and didn’t got it to play any UHD of HDR content. So i was happy that im at least playing something havent checked if it was 8 or 10 bits, but i expect 8. Ill check tomorrow to be sure
Thanks for the feedback. You shouldn’t have any issues with SDR content on any of the builds. The link with CEC is intriguing though…
I can verify mine is 10 bit.
No banding in the sky above the skateboarder in “The World In HDR”.
You guys can try and see if reverting the CEC settings back to default brings the problem back if you don’t care for the settings I use.
It’s possible that everything might still work after reverting.
Personally, I prefer these settings because I have my screensaver set to 5 minutes and when it kicks in it shuts my TV and soundbar off.
That way if I forget to shut it down it will do so on it’s own and I don’t have to worry about burn in.
I was an early adopter to plasma and I left my TV on over night once when I passed out and it had my desktop displayed the whole time.
It took weeks before the image retention went away (it did ultimately, but it freaked me out).
This method gives me some peace of mind.
Also it’s convenient to start watching the Vero too.
I just hit the home button on my Vero remote and that brings it out of screensaver mode which turns my TV and soundbar on as well.
By all means though, adjust the settings to what works best for your use case.
I’m glad it has helped some people so far!
FYI… My LG C8 just updated from 4.10.6 to 4.10.15 firmware and everything still works the same.
Not sure what the new firmware changed, I’ve only found reports that it corrected some HDR dimming issues.
Today I was not thinking and upgraded OMSC to the december release and again my 4K content cannot play. I thought no worries, I’ll just downgrade again but you have removed the code to downgrade. Can you please help me out?
