Need advice for a screen resolution (LVDS)

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?
