Hello,

I upgraded my old HTPC so i can finally watch 4K videos. The specs are:

Intel Core i5-7300U Processor
Intel HD Graphics 620
16GB RAM
265 GB for Libreelec
6TB for Movies
ELSKY QM9700/QM9600-6C​ Motherboard


​Everything is fine up to 1080p when I switch to 4K resolution  colors are totally washed out and everything is over exposed  with an excessive amount of brightness. This can not be fixed by changing settings from the TV.

Also when this happens I lose some settings from the TV, Saturation, Noise reduction, Back stretch and other settings disappear from the TV menu or are grayed out.
Anybody know what is happening ? Am I losing color space for some weird reason ? is this due to the cable not having enough bandwidth ?

To circumvent the problem I made a 2K custom resolution and the problem is not that evident there and can be fixed by settings on the TV.
The problem is present in Kodi menus and Movies. Any ideas ?

Check the details of the files with MediaInfo, could they perhaps be HDR as well as 4K?

The issue is with Kodi skins and menus as well not just movies, so the issue is not codec or HDR related

Does it just happen in Kodi or are other Windows programs acting the same? 

Do 4K videos look correct in VLC for example?

Is your display resolution set to 4K and if so does that look wrong?

Trying to figure out if this is an OS issue.

I am attaching photos so you see exactly what the issue is. It is not movie related the issue affects menus as well.











In HD brightness/exposure is fine:

Use limited colour range?

Also is that running at 1080i?

And the Netflix logo looks the correct colour at 4k but not 1080.

Limited colour range makes everything even more bright/over exposed
