[QUOTE 2829825, member: 45"]It's a 1 or a 0. This can't change over distance.[/quote]
Strictly speaking, that isn't true because there has to be a signal level at which the electronic decision is made. If there is sufficient degradation of the signal then a 1 could be degraded to a 0 or a 0 degraded to a 1. The longer the cable, the more opportunity for degradation to occur. A maximum length of cable is always specified. It might be 10m or it might be several kms but there will be a limit.
I worked on one digital system whose cabling was inadequate and it would crash every time somebody switched a kettle on at the other end of our office! We fixed the problem by using better quality cables with 'twisted pair' cores.
The thing about digital as opposed to analogue is that it can take a lot of degradation before problems result. My old analogue TV signal was speckly and had annoying ghost images. Digital Freeview, in contrast, works perfectly well in my house 99.something % of the time using just an indoor aerial but every now and then there is sufficient disruption to the signal to make the picture break up into squares or freeze altogether.
Anyway - that kind of thing does not cause images to be displayed with borders! I'm sure that there will either be a setting in software which can be changed to fix the problem, or that there is a bug in the software which needs to be fixed.
