I am very thankful for all experiences which youve described, really. Sorry my experiences are little different. I have to admit that my earlier post was based only in theoretical level but Ive promised to try it. In a few moments ago I finished attempt
with TMGS app. I have to say it is beautiful app with huge potential but on my Iconia W4-821 is not usable for turning screen off. The result is exactly equal as many small apps which are designed for turning display off. All these attempts are based on same
base but use a different ways. This is work on sending very specific instruction to system with expectation to provide a task. There is not any strange thing. Strange is only banding TurnOffDisplay function with Sleep function. Ok. TMGS and others can turn
off display but they can`t divide this two, in my opinion, key functions.
This isn`t right way. Sorry.
Very nice and simple attempt to turn off display is sending a screen to only second display. What a pity that Windows check connectivity and when discover that there isnt any other display than return back to previous status with warning message about impossibility to find second display. This one looked like real trick. Maybe in registry is possibility to turn off checking external devices but I cant do this.
