Firstly the screen can handle it, just play a properly formatted video using the media option and ou will see higher resolution.
Secondly the "bandwidth" should also not be an issue since this is traveling over a wire.
The biggest issue here would be drivers, and assuming that the open source OS software is used in all situations, the cameras would be selected for comparability so i doubt that would be an issue
Lastly, yes, some of us do back up that much especially when using the camera to hitch up. It would be nice to have a better resolution when hitching.
