  1. Strange multi-monitor/screen issue since last update.


    I have a strange issue with my computer since the last windows 10 update.

    I run on a two monitor setup but it seems that there is an issue where if I use an application in the 2nd screen the first screen loses all ability to gain focus. I can't click or do anything in that screen. If I bring up task manager via ctrl-alt-del which starts in the first screen, the first screen becomes active again and I can select items in it. If I however drag task manager to the second screen, the first screen again becomes unresponsive. I have to close down the task manager and start it up again from the ctrl-alt-del menu.

    Is this a bug with the new update, or did something not update correctly?

    This is on Win 10 Pro 64bit.

    i7 CPU

    8 GB Ram

    Nvidia GeForce GTX970

    Windows 10 KB3213986 Update Cripples Multi-monitor Gaming

    The recent Cumulative Update for Windows 10 (KB3213986) cripples multi-monitor gaming, looking at the way Microsoft worded its "known issues" text. After the update is applied, users with multi-monitor setups could experience screen stuttering or clipped screens when running 3D apps on machines with more than one monitor. The only workaround Microsoft suggests for now entails running your 3D apps in non-fullscreen modes, such as windowed-maximized (pseudo-fullscreen) or windowed modes. Microsoft also goes as far as to suggest that people with multi-monitors could try starting their 3D apps with just one monitor connected.

    "Users may experience delayed or clipped screens while running 3D rendering apps (such as games) on systems with more than one monitor," the change-log for the KB3213986 update reads. "To work around this issue please consider the following options: 1. Running the application in Windows mode (not full screen), or 2. Starting the application with only one monitor connected," it adds. The update effectively cripples multi-monitor gaming, using technologies such as AMD Eyefinity or NVIDIA 3D Vision Surround.

    That's what the auto setting will do since you're over the 1333 mark it jumps to the next step which isn't listed or officially supported I assume by that ram.

    At this point though I would suggest dropping the multi one step or .5 so that we can get something stable and possibly take the heat issue out of the picture for now.

    Second monitor screen resolution problem


    For us to properly isolate the issue with your second monitor screen resolution, we would like to know the following:

    • Were there any changes made on your computer prior to the issue (e.g., updates, software installation)?

    • When did the issue first begin?

    • To make sure that we have not missed on anything, what troubleshooting steps have you done so far?

    In the meantime, we suggest that you try resetting your monitor settings, and check if the issue still persists. You may refer to your monitor on how to reset it.

    We look forward to your response.
