[PROBLEM] Kodi 14.2 forgets screen calibration

[IriDium]

No idea what has changed. Can you:
1) Check /boot/config.txt and check for any overscan entries. If none, then: goto 2
1a) If there are overscan entries, comment them out, reboot and see if that helps.
2) run tvservice -d tvservice.dat
3) run edidparser tvservice.dat > tvservice.txt
4) run cat tvservice.txt |more

Look for the:
HDMI:EDID found preferred CEA detail timing format xxxxxx
and later on
HDMI:EDID found CEA format: code yy which matches the above.

set in config.txt
hdmi_group=1
hdmi_mode=yy

and reboot.
