Hi Shingo,

I suggest you an wiki article provides some examples of using sysfs interface to change display settings including switching the display output between TV and LCD.

Hi Tsvetolin Shulev

Thank you for your infomation.

I try it, but I Incomprehensible this process.

Is it change Linux Driver?

Or Would operation from matrix-gui?

Shingo,

The linked above article provides some examples of using sysfs interface to change display settings like selecting active overlay, manager and display but it didn't make any changes in the display driver.

I am sorry for the late reply.

I understood your advice now.

Try change output command, but target is not changed.

I change this path init files.

/ti-dvsdk dm365-evm・・・/example-applications/matrix-gui-e1.3/dm365/etc/init or ・・・/dm365/x11/init

This code is following.

=======================

echo COMPONENT > /sys/class/davinci_display/ch0/output -> echo LCD > /sys/class/davinci_display/ch0/output

echo 480P-60 /sys/class/davinci_display/ch0/mode -> echo 480x272 >  /sys/class/davinci_display/ch0/mode

=======================

This change code is sample in the matrix-gui-e start code.

Can I understand?
