I have set the attached LCD display to off in the BIOS -- no help. Device Manager lists Intel Corp driver version 188.8.131.5249 11/10/2016.
Just clicking on the Windows icon at bottom left to go from win 7 type screen to win 10 display will cause a slow black refresh. If I leave the curson sitting there the screen will continue to alternate with 5 second black screen.
I am using Logitech K400+ keyboard and M570 track ball with logitech Unifying Software and the dongle is the USB-3 slot.
Even when I pull the dongle out the screen cycle continues.
Moving the dongle to USB-2 slot made no difference.
Screen is 12 inch 1920 x 1080 Text size 150%
I incorrectly reported this issue in the Alpha area.
I have applies the latest driver from Intel.
I have tested of second K4 display -- even more problems.
I do have a 3 amp supply.
Additional noticed problem. when I select power from the windows icom first I get a malformed box for sleep shutdown restart , then a correct display. If i select shutdown the screen freezes, no more mouse movement on shutting down screen just frozen. on the other hand is I bring up task manager and select the power options from the right bottom is see the normal windows actions.
