    So I'm confused as hell as to why this is happening.

    I just bought a new sony 55x900e TV. My MSI GT73 1070GTX windows 10 is connected to my TV via HDMI 99.9% of the time. The first day I had no problems, the second day I woke to find my screen projected to second screen (TV) when I didn't tell it to do that. Since then (a week ago) when the TV is off the laptop will automatically project itself to the TV. Sometimes It takes less that 1 minute when the TV is shut off, sometimes 10 minutes. I thought it randomly choose projection types (duplicate/second screen only/extend) but it seems like whichever projection you manually used last is the one it will switch to by itself when TV is off. It will not switch by itself if the tv is on, even sitting idle on hmdi 1 with no input or when playing netflix...etc. If the TV is on it won't project unless I make it but as soon as that TV is turned off its on the clock, it will even switch when I'm using the laptop and typing/browsing/listening to music or watching a video.

    I have rebooted both TV and laptop, reinstalled the nvidia drivers from MSI using DDU and safe mode, the tv is up to date, windows has done no driver updates, I have tried 2 different hdmi cables, I have tried plugging in to hdmi 2/3/4. I called sony, they said the TV has no control over the source. I have uninstalled and disabled PnP monitors that pop up in device manager when I hook it up to the TV. Laptop confirmed as #1 screen and audio is defaulted to laptop. It is driving me insane.

    I know I can simply leave it unplugged but I shouldn't have to. WTF is making it do this? The new TV replaced a 2015 kdl55w800c Sony tv that didn't ever do this. I can't even find a process to disable that stops the switching.

    It's probably not the drivers. Have you tried updating your Windows to like the latest build? What about BIOS & EC?

    Yep, build 1803 happened last night and it did not stop it from auto switching when the TV is off. BIOS&EC are up to date too unfortunately.

    You didn't have this issue with previous TV though, right?

    Nope. It was a sony kdl55w800c. I think it was a 2015 model and this one is a 2017 model. Same OS interface too just the new screen has HDR/4k and some other extras. The laptop didn't do this the first day I hooked it up to the new TV, it started the day after.

    Have you tried a different HDMI cable? What about power options? Standby options?

    Tried 2 different cables and tried plugging it into hdmi 2/3/4 also. Power options it never goes to sleep, I tried changing screen turn off time but it also did not work.

    One thing we don't have to assume, is that it is the laptop itself as the issue. You mentioned the previous TV did not do this. Why is suddenly the machine the issue? You actually performed a lot of good troubleshooting and updates for drivers, bios etc.

    The only other thing to try is not using HDMI directly, but the DP port with an HDMI converter to see if it has the same behaviour. The issue sounds like very annoying.

    It could also be somewhat related to windows itself, but what strikes me the most as odd is that you didn't have these issues with a previous TV. Do you, by any chance, have any other display you can test to see how it behaves? We need to rule out which one is/isn't causing the issue. It may be a combination. You can also try looking for a firmware update for your TV.
