Sometimes when I play a 4K HDR movie and I return to the menu the menu is shown with a very low resolution. I then have to go to settings and resolution is displayed as 1080p (whilst it is not). I then manually need to select another resolution and then return to 1080p to restore correct display.
Vero 4k is connected to a LG Oled TV
Is this a known issue?
Go to Settings -> Display and enable HPD Lock and reboot.
Are you using the recommended setup?
We recommend people with 4K TV’s set their user interface (UI) to 1080p. Kodi’s UI is not optimized for 4K yet and this can put unnecessary demands on your device and can lead to a suboptimal picture quality, as well as potentially cause other issues.
The settings we recommend are as follows…
Settings>System>Display>Resolution> 1920x1080p
Settings>System>Display>Whitelist> (empty)
Settings>Player>Videos>Adjust display refresh rate> On start/stop
Some televisions may also need, or benefit from, the following being set…
System>Display>Force 4:2:2 colour subsampling> (enable)
With the above settings your UI will be output in Full HD and your 4K content will be output in 4K. If you have any doubt, feel free to upload some logs so we can verify that your settings are indeed correct.
Movie and video play fine at 4k. UI is set to 1080p.
Sometimes when playing 4k HDR content and I return to the interface it is changed to low res. Still indicated at settings as 1080p. I wil l try hpd lock first
Take a look at my thread here: Occasional resolution drop issue
I had a similar issue. It seems mine was caused by rebooting OSMC while the connected devices were switched off, so it couldn’t read the EDID information.
