Ok, so I don't get HD although I have got a standard Sky box. I might buy a Blue Ray player in the future but not until the prices drop significantly. I am not a TV geek so I don't need full HD 1080 and I'm about to buy an LG42PG3000 (LG 42" Plasma) because I can get one for £399!!!

Is this a wise move or should I fork out the extra £300 or so to get full HD?

what sort of quality picture will I get? Will it be as good as the 28" JVC flat screen tube TV that I've got at the moment. If so that's good enough for me! wink

Please don't reccomend that I buy a Panasonic or Pioneer, I know they're better but they're 4 times the price too!

It'll probably be fine and unless you are a techno geek you'll probably not care that you can't get HD and it'll be some years until everything is on HD anyway.

Personally I got HD, because I knew I wanted Blu-ray player and PS3 and it means its slightly prepared for the future (a mate of mine spent about 4 grand on an early 42" plasma and it doesn;t have HD - think he's a bit guttted), but for the price your paying I wouldn't care. and It doesn't sound like you are bothered, chances are picture quality will be fine

It's HD ready but not full HD (i.e 1080)

For 399, doesn't matter.....720p still looks grand on a 42", buy it.

Will do smile

It's factory 'graded' which means it has been out to a customer but returned within 28 days, fully reconditioned, with a 12 month guarantee, as goos as new, might not be in original box but hey, Richer Sounds are punting them out for £500 so I really dont care.

It may be HD ready but it is only 1024 x 768, you need 1280 horizontal resolution for 720p.

Fine for SD though.

Your not wrong, didn't realise.

I still don't think you'd notice any significant difference if you're at a sensible viewing distance. 399 is a hundred odd quid (at least) cheaper than anywhere I can find too and LG make good plasma telly's.

Where you getting it from at that price? Any chance you could haggle a bit off given it's not quite up to the 720p thing?

Still a good buy IMO.

Yes and No.

To achieve a 720p without scaling requires a screen resolution of 1280x720.

However, as far as the eye is concerned scaling of vertical resolution is far more noticeable than the scaling of horizontal resolution. So whilst the source image maybe output at 1280x720 the processing to fit it on a 1024x768 screen will lead to an imperceptible difference from the viewers perspective.

Resolution in isolation is also the 4th most important component in image quality, 1366x768 for instance is a common LCD resolution, however 1024x768 is more common on Plasma. The improved brightness, contrast and motion processing (specifically due to the mathematical algorithm within the scaler) on the plasma means that despite the scaling that is occurring to accommodate the 1280x720 image on a 1024x768 screen that the resultant PQ is better on the 'lower' resolution screen.

In summary whilst the assertion is technically correct pre-scaling, from a viewing and image processing perspective it isn't.

Thanks for that Plotloss however, your technical explanation was way over my head. I just want a decent picture when I turn the telly on! wink

Only if you want 1:1 pixel mapping which is not a requirement of the HD Ready label. I believe that the only requirement regarding native resolution is that the number of lines is greater than or equal to 720 and 16:9. It must have at least 1 HDMI socket that can accept 720p or 1080i.
