350 is connected to router in the same room by Ethernet cable. OS is windows 8.1 and when viewing, picture size is significantly reduced similar to when watching and old non digital TV series through a digital tv. when connected to the TV via HDMI the picture is even smaller like a square in the centre of the screen probably about half screen size. Is this a Windows 8.1 problem or is it a connection issue? Anyone got a view on this?
