Help me manage my multiple monitors
So my current setup is multiple monitors but not in the normal way. I have my computer room with my computer in it and my new widescreen monitor. In my living room just one room over, I have my 4K TV which is also connected to the computer via an extra long HDMI cable. Its pretty nice. I did it this way so that I can choose to game on either. I generally still watch episodes of stuff or youtubes or whatever from the TV. The monitor is a curved ultrawide 3440p x 1440p and the TV is 4k.
However there are some things I need advice about. Seems like windows gets a little "particular" about which monitor is set to "primary". Icons jump around. Programs open on the screen I don't want them to. If these monitors were directly next to each other it wouldn't be so bad but they are in other rooms. Its a bit annoying. I know there are some third party programs I can buy to assist me in this, and I am open to that. I just don't know if they are truly necessary or if I can force windows 10 to cooperate. Also I don't know what third party apps are good to get.
So basically: I want to have it so the monitor and TV both have their own desktop icons that don't switch around when I toggle primary monitor. I want it so that if I open an application from a certain monitor, it pops up on that monitor. I want to be able to still toggle primary monitor for the purpose of changing which monitor I am gaming on. I don't generally click and drag programs from one screen to the other because like I said, they are in different rooms.
Any advice is appreciated!
