Intel VAAPI howto with Leia v18 nightly based on Ubuntu 18.04 server
(2015-10-08, 01:29)Sunflux Wrote: What projector are you using? If dithering is having such an impact, then it sounds like you aren't actually outputting limited via the new passthrough option (I haven't seen dithering do anything visible in Passthrough mode, but it definitely has an effect in Full mode, which is less ideal).

I am using a Viewsonic Pro8200 projector.

So to test your theory, I loaded up the black bars and increased the brightness on my projector. I see bars below 15. Does that mean Full is getting passed? FYI, my projector is set to Limited.
