I have always been using this:
- Full range xrandr, limited kodi + limited projector
I guess I thought I was going to be able to get rid of the limited kodi as the washed out blacks in Kodi are a bit annoying but no biggie.
Since I have always been doing this - should I really see a change? I assume there is nothing really different?
I could run full on the projector but I would have to switch for other sources so doesn't seem ideal.
Thanks!
Washed out blacks are a sign that something is wrong in your configuration. The stuff being discussed here is about removing or minimising banding. Previous builds have had the capacity to get black levels right for both limited and full range displays.
A well set-up system should have black blacks...
just to make this clear.
- Full range xrandr, limited kodi + limited projector
this does not work for vaapi non-EGL. this is not only about banding but also about having foot and head room aka wtw, btb
Yes - that is the other benefit - though well mastered content should only have over/undershoot transients <16 and >235 and shouldn't have 'real' content present. (The headroom and footroom is there to avoid clipping over and undershoot on transients - particularly on older analogue sources that have been digitised. If you don't preserve them and process them you can end up with ringing etc. due to clipped transients. Of course if your display is scaling, processing etc. and you have clipped transients in your output from Kodi, you could see artefacts introduced I guess, so preserving <16 and >235 is definitely a good thing.)
