HDMI display power control on Apalis i.MX6 toradex board


I want to control the HDMI display (x17 connector) power on Apalis i.MX6 toradex board.

Need to power ON and power OFF the HDMI display.

Can you please help me on this ?


Does this help?

It looks good, thank you.
Is it possible to power OFF backlight of the display ?


There is no signal which controls backlight on the HDMI connector. Its the HDMI monitors responsibility to switch of the backlight if no video signal gets detected.

If you do not use a HDMI monitor but a LCD display with a seperate backlight inputs on an additional connector you could use the BKL1_ON and PWM_BKL1 signals to control it.
