Andy

Pls see https://pastebin.com/CHmu9s22

I put dumps for following scenarios:

1.
-boot
-modetest -s 69 at 67:1920x1080 -> ok
-modetest -P 43 at 67:1920x1080 at NV12 -> green screen


2.
-boot
-modetest -s 69 at 67:1920x1080 -> ok
-modetest -P 49 at 67:1920x1080 at NV12 -> ok (but shifted horizontally by about 5% of screen width)
(setting palne#49 fixes plane #43. Here i set plane #49 but not yet setting #43)


3.
-boot
-modetest -s 69 at 67:1920x1080 -> ok
-modetest -P 49 at 67:1920x1080 at NV12 -> ok (but shifted horizontally by about 5% of screen width)
-modetest -P 43 at 67:1920x1080 at NV12 -> now ok (but shifted horizontally by about 5% of screen width)
