First post here. I have two M1 slingboxes, When I connect to my old(first) one and I cast it through Chromecast the video is a full screen on the TV. When I connect to my second and most recent box the screen is very small. I am using an Ipad to cast through Chromecast. I have tried to find a way in the settings but haven't found a way. The slingboxes are connected to different cable boxes. I am not sure if that is useful information.
