Hello, Having built the robot and tested it, I would now like to use the Xbox controller, but part of the software screen is missing on the right-hand side (as image). I have edited ARCS.py at line 70, but it doesn't seem to make any difference. Any suggestions would be appreciated. Thanks,
Lee.

have you tried setting the windows display setting to 100% ?
Yes, the display setting is set to 100% and I have tried other settings without success. The next thing I can try is to use a widescreen monitor to see if that makes a difference.
Let me know if that works, im curios what the issue is.
Plugged in the wide-screen monitor which allowed me to see half of the Xbox icon, a slight improvement but still not full screen. This allowed me to at least activate the Xbox controller. I then plugged the cables back into the other monitor and could see the same screen, but it was distorted. I rebooted the PC and the original screen appeared, but no Xbox icon . I'm not quite sure what the issue is, but it's as if Windows remembered the settings from the wide-screen monitor which was then output to my normal monitor when plugged back in.
What is the screen size on your PC and monitor?
The screen size is 15" wide x 1 high and the resolution is set to 1280 x 1024 (the highest).
are u run windows with macbook? seems like retina display double up resolution
No, I am running Windows 10 on a PC.
