FYI my q8h-v1.5 uses a slightly different mode line:
x:800,y:480,depth:18,pclk_khz:36000,le:45,ri:209,up:22,lo:22,hs:1,vs:1,sync:3,vmode:0
Yes, there are multiple modelines floating around for 800x480 panels, I've
2 A13 tablets and the modeline of the fex file from tablet a causes the images
to not be properly centered on the screen of tablet b. Luckily the other way
around does work, so for the q8_a13_tablet_defconfig I'm using the modeline
from the fex file from tablet b. I hope we can do something similar with q8
a23 and a33 800x480 tablets.
I've been buying q8 tablets with cracked screens (people seem to drop them quite
a lot) for cheap from a local 2nd hand website, so now I've 5 ever so slightly
different models, I still need to make a generic q8 config for those, and see if
I can find a modeline which works on all of them.
That modeline should probably be a good one to use for the a33 defconfig too.
I'll find some time to give yours a test.
Thanks!
Regards,
Hans
