That's going to depend a quite a few things.
- How's your eyesight
- What distance are you sitting from the HDTV
- What's the resolution of the content you're viewing
- How do you feel about analog audio
For the most part, I'd say no, it's not going to be "vastly" superior. Whether you even notice a difference or not is mostly dependent on the above questions (IMO).
hey mate, i bought a plama yesterday and my digital tv runs without interference, my xbox and playstation also run without interference ... yet my SKY BOX gets interference every single 10 seconds.. ive rang the manufacturers and they said i need to buy a 1.4 hdmi cable!! im a bit sceptic because i have 4 hdmi cables here and the same problem happens on every cable, but the tech support team says they most probably aint 1.4 cables.... can you help at all please? any advice will be great
