1920x1080 screen
1366x768 game window
1229x768 screen area
Everyone uses such tiny areas, must be hard.
Edit: Just noticed YayMii and I have the same but reversed settings, kinda funny.
Impossible to get 16:10 at 768p ;_; (it's 1228.8 for the width so I just rounded up)
I'll probably switch to 1152x720 screen area with 1280x720 game window.
You can get more precise mapping by using the Mouse keys
[ Control Panel\Ease of Access\Ease of Access Center\Make the mouse easier to use ]
First I set the game window to the size I want my tablet to play with (I always use a 16:10 resolution) then I use the mouse keys to get a precise placement. Then I just switch the game to a 16:9 resolution and play on that.
I never change the tablet area. I really wish I had a bigger tablet so I could play on bigger resolutions and match the movements. I find if you're playing with a large resolution the inputs get misplaced because you're not moving the same distance as you are with your tablet.
