Video 62 shade of grey, 3x 6bits: 18bits

[Félix Hauri]

Dears,

Thanks for your suggestion, sorry for this late answer...

Yes, 16 (5+6+5)bits instead of 18 (6+6+6)bits seem acceptable!

Unfortunately, this don't work: I think I have an Endianness problem.
For who's interested, I've posted some photos of resulted screen here:

Note: Due to antialias, text is very hard to read.
