Touch screen go off when dimming

[faspina1]

I have a 7" touch LCD hooked up to the PI running MM. Going to use it as a smart alarm clock. I have it laid out like I want I am working on a way dimmer.

Using REMOTE_ACTION. Dimming the screen to about 50 (out of 255) seem to turn off the touch functionality.

Are better ways to dim the MM screen. I don’t want to turn it off.

Update: Tried in on a 5 inch lcd and in server mode with broswers. Same issue
