OpenELEC Testbuilds for RaspberryPi Part 2
(2014-03-21, 12:38)doveman2 Wrote: It seems the Pi is still clipping my black levels, despite setting
hdmi_pixel_encoding=2
in config.txt, which is meant to be RGB Full (0-255). I'm testing with a black clipping pattern showing levels 0-25 and when I play it from a USB stick on my TV, if I increase the brightness the lower bars will show up as grey rather than black but via the RPi, it doesn't change which bars are visible at all. Is there another setting in XBMC which would cause this?

I've also found that with my TV (Panasonic X60B plasma) that playing the pattern via the RPi and setting the brightness to +2 - +4 shows noise/snow (dithering?) all over the picture but playing it via the TV's USB port this doesn't happen. I also see this noise on the XBMC menu background.

EDIT: Another thing I've noticed is that the thumbnails in Videos - Files look like they've had the brightness boosted, so that they look very different to how they do when played. I took these screenshots in the list and with the videos playing to show the difference.

I think the x60 doesn't support full RGB range. So you should remove hdmi_pixel_encoding=2 and choose from the xbmc settings limited color range [settings/system/video output - enable use limited color range (16-235)].
I'd also suggest setting contrast and brightness at 50 on xbmc and whatever calibration you do do it from tv's menu.
(Panasonic UT30 plasma owner here, everything is good with the above).
