    On a new 4G 64G card with most current Windows I am seeing slow windows screen refresh. Just moving the cursor may give a black screen for as much as 14 seconds.
    I have set the attached LCD display to off in the BIOS -- no help. Device Manager lists Intel Corp driver version 20.19.15.4549 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%

    Advice?


    I incorrectly reported this issue in the Alpha area.

    Updates:

    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.
    Sorry, but no advice :(
    But I moved and merged your topic ;)

    I am returning to check to see if there are any comments for the bad screen updates. I see none.
    My purchase is JUNK and support is ineffective. Too bad! :cry:
