I know there has been a post or two about the screen size scaling not working correctly on the AR4 application. I am running the 3.0 software version and have the screen being cut off so I cannot access the additional axis' on the right hand size of the screen. I am running 1366 x 768 resolution and %100 sizing. With a Lenovo laptop, windows 10 and a 15" screen. I have tried suggestions previously mentioned. However no luck. I have only been able to find screen sizing options in the display tab of the settings applications. Nothing through the control panel which i have seen other people have success with. I just do not have any options to modify in the control panel of my computer. I cannot even plug into an external monitor and it run correctly. I have tried on a 65" screen with no difference.
