Professional HD TV Services
Modern televisions can show far more detail than older screens. However, a larger or higher-resolution TV can also make weak signals, poor cabling and low-quality sources more noticeable.
If the picture looked fine on your old TV but now appears pixelated, stretched, soft or grainy, the issue may not be the TV itself. The signal path, cable quality, source device, channel type and TV settings should all be checked before deciding what needs upgrading.

- Freeview HD and Freesat HD advice
