I’ve been trying to optimize video on my Vero 4k. I already discovered a few new things about my setup, for example:
1.) If I set “display 4:3 video” to “HDMI AVI Signalling”, my TV jumps out of its “no-overscan” (correction = zero) mode. For example, while my GUI is set to 1080p/60 Hz (in no-overscan), when I start playing a 50 Hz movie, the TV frequency changes to 50 Hz. When I stop playback, it changes back to 60 Hz, but it is no longer in no-overscan mode and I would need to apply significant correction in Kodi. I thus reset the option to “normal”.
Is this behaviour a common occurence? (I have an older Grundig TV set.)
2.) When I use the Whitelist to enable direct-output at 576p resolution, the picture doesn’t fill the screen: There are black bars at the top and bottom (not at the sides.) No, these are not letterbox bars, they are much smaller than that. I found that I can adjust “pixel ratio” while playing. A value of 0.94 gives me a full screen picture.
When I repeated the test with the same video just now (after being powered down for a few hours), this value was already set, even though I can’t recall having saved it myself.
Is this value saved automatically? And does the saved value apply to all video, or just the resolution/framerate combo that it was set for in the first place?
