  1. When using HDMI, forced to lock screen


    Hey guys. Recently updated to Windows 10, and I watch a lot of tv through my laptop by HDMI to my HDTV. Before with Windows 7, I NEVER had an issue like this.

    After somewhere around 15-20 minutes of the HDMI being plugged in and watching via my TV, the computer locks itself. It goes to a black screen and "disconnects" from the HDMI input. BUT the programs keep running, but I can't see or hear them since it doesn't go back to laptop input. To bring it back I have to click the mousepad and it brings me right to asking for my password. How do I stop the laptop from ever locking while I'm watching or streaming through HDMI? It doesn't do it when it's playing straight off the laptop...

    :)

    Windows 10 - No Sound after lock screen

    After my computer goes to the lock screen, and I am forced to reenter password to go to the desktop, I never have sound, and am forced to restart the computer to regain sound. This only happens after coming out of the lock screen. It doesn't matter path
    to lock screen. It could be revering from sleep mode, or it could be recovering from me changing the channel and w10 recognizing I changed channel and forcing lock screen.

    Regardless, I am unable to fix this. It is definitely a windows 10 issue, no drivers have made any change to this. This issue was not present on windows 7. This happens on all version of and only windows 10, including insider programs.

    The error is that another program is using the device.

  3. Force Display Output via HDMI Port

    Windows 10 Question: The goal is to display two screens (same video screen) from the computer to two projectors for a presentation using Power Point Slides. Attaching to one projector works fine, but when I attach a HDMI splitter to hook up the second
    projector, the computer no longer detects the display and will use the HDMI port as an output.



    Thus, can you force a video output from the HDMI port using Windows 10.

    When using HDMI, forced to lock screen

    Have you checked the screen saver options under control panel , check it's not been toggled on when you switch to HDMI , there's a tickbox there too that tells the laptop to go to the login screen when the display is resumed which might explain the login coming up.

  7. Juice, I followed the link and already had all of those settings applied on my computer. Also, graphics driver:

    AMD A6-3420M APU with Radeon(tm) HD Graphics 1.50Hz

    When I go to Windows Update, it says there is nothing left to update. Can I manually find if this driver does need to be updated but Windows just doesn't recognize that?
