Press the power button on the monitor to turn on the monitor.
The power light on the monitor should be off. I tried the battery, security, and other obvious options, but I see that a lot of people have similar problems, without a simple, single fix-it option. Cycle the power on the monitor as follows: 1. This display timeout/lock even happens while I am on a call in the USA, and the phone page with time-out. Now we are getting better 3 or 4G settings in poor countries in Africa and Latin America, I am using my cell for work related research (while on int'l & local travel delays, and waiting on meetings, etc.) but this display time-out issue is more than annoying, it is costing me a lot of time problems that I did not have with my other phones. These same processes can be used to change to duplicate if you’d. I do a lot of traveling internationally, and in between delays for meeting people, I do research with my unlocked Samsung Galaxy 7 Edge via the Internet during the many travel and meeting delays in my int'l development work (where I cannot pull out my laptop). Step 4: Go back up to the diagram and use your mouse to drag your second monitor to the left or right of your primary screen. I tried all the above options, battery conservation, etc., but nothing is working.
Yet, this thread seems most closely related to my problem, about the screen display repeatedly reverting to a short 20 second (or shorter) display time-out while I am reading it. Sorry to read some of the comments above, but it does not surprise me since I have had similar experiences.
