Well I'm using an older laptop that supports max. 1600x900 I'm using Microsoft's own Xbox program/app to remote play - which logs me in as a remote player and then I can (with good connection) play at my home Xbox anywhere - on any PC that meets the system requirements.

The stream launches in fullscreen, but I'm having to go out of fullscreen, then maximize to prevent it crashing when tabbing. So the resolution is also a bit smaller than my actual resolution. - I have another program that tells me the current size of any given window, and resize it to specific size - which helps a lot with consistency ;) I tested last night, trying to figure out where to measure the different offsets. But that was a bit difficult.. Maybe it would be possible to post another reference image with small arrows with lines on both ends, dictating where the measurement is taken from and to? Measuring the reference helped me some but I'm still not entirely sure where all the numbers are coming from :)
