Hello.
I need to output video with 1024x768 resolution and RGB24bit but with unusual 50 FPS (as I know 60 is default) to display via LVDS interface.
At first, as I understand, I should to set video mode in u-boot.
Example of eEnv.txt: video=mxcfb0:dev=ldb,1024x768M@50,if=RGB24,bpp=32
(You can see that I setted non-standard @50 FPS in that example)
Should I also change devices tree (for example, section &ldb, or something else) ?
Also I can't find information about output RGB format.
So, there are two main questions:
* Is it possible to use non-standard FPS and what I should to make it possible?
* Which is output RGB format, JEIDA or VESA?
Thanks!

one can look at "refresh" setting in struct fb_videomode[] AN3974 p.24:

Do you know something about output RGB format?
For example if I'll set "if=RGB24" will it JEIDA or VESA?

Thank you!
Thank you for hint, however there is no information about settings FPS and how imx.6 does processing that settings.
