I have a primary ultrawide monitor running at 3440x1440.
I also have a secondary monitor running at 1920x1200.
Whenever I start ESO, every single time, whatever I'm running on my second monitor will flip and move over to my primary monitor, forcing me to alt+tab out of the game to adjust it back while the game is running.
Likewise, every single time I start ESO, it starts in what appears to be the wrong resolution. When I go to settings, it lists as 3440x1440, but the graphics are very low-res. So every time I need to switch the game from Fullscreen to Windowed Fullscreen and then back to Fullscreen again to fix the resolution problem.
I repeat: I have to do this every single time I start the game and it's been like this for a long time.
I have Windows 10 and a GTX 1070. Both Windows and video drivers are updated.
