Fix/Change Windows 10 Lock Screen Timeout on Surface Pro

I always read email message on my Surface Pro 4 and the screen keeps timing out the way too soon in Windows 10 anniversary Update, so I make changes with the length of inactivity time by this method. Right click any empty area on Desktop, select Personalization > Lock Screen > Screen time out settings, and choose your required time in the drop down menu.However, no matter what I set the length of time to, the screen will keep timing out at 1 minute. If I configure the the displayto “never sleep” in Power Options, it doesn’t take effects and the tablet goes to sleep after 2 min. How can I resolve the problem?
