I can configure my i.MX53 QSB to HDMI+VGA dual monitor by the following settings:
A. UBOOT
setenv vga_hdmi 'video=mxcdi1fb:GBR24,XGA di0_primary tve video=mxcdi0fb:RGB24,1080P60'
setenv bootargs_base 'setenv bootargs console=ttymxc0,115200 ${vga_hdmi}'
B. Add dual monitor settings in /etc/X11/xorg.conf, just like suggestion from http://www.imxdev.org/wiki/index.php?title=I.MX53_QSB_Ubuntu_Dual_Display
=============================================================
My questions are :
A. Play video in main display (HDMI) with full screen mode by above setting will cause IPU error, is it possible this problem be solved?
B. It seems can not play video in 2nd display (VGA), is it possible this problem be solved?
C. The VGA resolution is 1024x768 by above setting, can I increase VGA resolution? I have tried to change XGA to SXGA in UBOOT, but it will cause both HDMI & VGA no signal at all. However, SXGA is working fine to 1280x1024 if only single monitor setting to VGA (without HDMI).
D. If I change HDMI setting from 1080P60 to 720P60, and VGA keep as XGA, same problem occurred, both HDMI & VGA no signal at all. Can't I set up HDMI to 720P ?
Please help, thanks.
