    Multi-Monitor dragging windows between screens resizes window


    I recently retired a laptop that had it's own screen as 1920x1080 and had a second monitor plugged in that was set to 1920x1080 and when I dragged any application's window between screens, I would see no change in size of the window being dragged. I could move back and forth and the size would never change.

    However, my new laptop (an Acer Aspire 5) which also has it's native screen 1920x1080 and has that very same monitor now plugged into it and set to 1920x1080, now when I drag any window across from one screen to the other, the window resizes. I see it change exactly as it passes the threshold of the window being 50% on one screen and 50% on the other. I can wobble it back and forth (left/right) at this threshold point and see it being resized up/down in height by a roughly 100-150 pixels. It's not the most annoying problem to have, but annoying enough.

    When I right-click on my desktop and choose display, I see that both screens are set to 1920x1080 and I have them in a 2:1 layout and have the external monitor (display 2) as the main screen and have my start menu/toolbars on there (with vertical layout on the right side of the screen). I don't know if this is relevant ... as I drag the window, it goes behind the start menu/toolbars as it crosses monitors.

    Setup:
    Acer Aspire 5 15" 1920x1080p i7-8565U 16GB, External monitor 27" LG 1920x1080. Windows 10 Home.

    Native Resolution of the laptop vs monitor.

    That's what I assumed, but the laptop's native screen is/was claimed to be 1080p and the same applies to my monitor, and both report (in the desktop settings) to be at that resolution and I have a utility from midiox.com that saves/restores the desktop icons (for those times when they get nuked into auto-positions) and it says when saving that both are the same.

    1080p is the HD resolution. It is the screen size that the mfg has coded into the GPU, for what they have determined to be best for the LCD screen. You will see this with certain devices, but it should not be happening in your case.

    Are the "Settings / Display / Scale and layout / %" the same for both displays? Also check "Advanced scaling settings" under that % setting and turn off the "blurry" fixer (reboot after) so see if that changes anything. I've had some weird things happen with some apps that should be DPI aware, but don't REALLY act like it.

    AAaaaarrrrrggggghhhhh !!!!!!!!!!!!!
    How did I not see that? One display was set to 125% scaling and the other was set to 100% scaling. Now they're set the same and this behaviour immediately stopped without even needing a reboot.

    Thank You !!
