best picture quality led hdtv image
noonah
I have connected my sky+ box to it using the scart lead. When i sit further away from the tv the picture looks better but it is not great closer up. How do i get the crystal clear picture that you expect with a tv like this? I'd appreciate any help you can give. Thanks.

I don't live in EU so don't have hands on experience with SCART. But to my understanding SCART is a Standard Definition connection only. It can't do HD. You need to use HDMI or Component in order to actually feed your TV HD.
Plus you also need an HD box from Sky. Depending on how old yours is, it might be one that only does SD from it. You want to get that upgrade to an HD capable box.
If you are sending SD to your HDTV, you're going to encounter some visual defects. And just like you describe, they will seem less noticeable if you're far away and more noticeable if you're closer to the screen. But either way they will be there.
The reason is that SD (PAL) is a aspect ratio of 5:4 and a resolution of 720x576. But HD is an aspect ratio of 16:9 and a resolution of 1920x1080 (in your case as you bought a 1080p TV). So there is a discrepancy on 2 fronts.
As a result your TV has to up-scale the source feed (the resolution) for sure. There's no way around that one. So that will add some quality loss. Then it has to deal with the aspect ratio problem. It can either stretch the image horizontally (breaks the aspect ratio, but doesn't add to much more degrading of the image), or it can zoom the image (maintains the aspect ratio so people aren't stretch, but further softens the image). This is just the nature of watching SD content on an HDTV. You will get used to it, everyone does.
The best way to get crystal clear images on your new HDTV is to subscribe to HD broadcast programming and to get a BluRay player for HD movie viewing. Anything that is still PAL (SD) is only going to look so good.

Does plasma still offer the best picture quality?
edwnc
Ok, so LED TV is all the rage these days, LCD is slowly improving, and DLP...well it's still DLP.
From what I've heard, despite the improvements other TV technologies have made, Plasma still offers the best picture quality (even over LED). Is this true? I'm looking to buy an HDTV and would like to hear from all of you...which type of HDTV offers the best picture quality?
Answer
Yes, Plasma still has the best picture quality!
The only advantage it's closest competitor has(LED TV) is in energy consumption! LED LCD TVs use up to 50% less energy then standard LCD or Plasma TVs! But what's the point of saving money on energy when you have to pay so much more for the TV? It's negating the energy savings!
Otherwise...Plasma TVs still have better "native" contrast ratios. Up to 5,000,000:1 in some 2010 models! They also have the fastest response times(.001ms) and fastest refresh rates(600hz). Making them the best at producing the sharpest and smoothest motion possible. Perfect for fast motion content like sports, movies and gaming!
The reason i used "native" contrast ratio rather then "dynamic" is because dynamic is a useless number! The definition of Dynamic contrast ratio is the measurement of a TVs ability to render it's blackest black and whitest white in a non-specified amount of time or frames. I don't like going by a TV's dynamic contrast ratio because this number is not controlled by any other source other then the manufacturer of the TV. So basically the manufacturer can use any or all means necessary to get this number! There's no way to prove that the TV can actually obtain this number!
Native' contrast ratio on the other hand is considerably more accurate and a better number to go by if you want to get an idea of the TV's picture quality capabilities! Native contrast ratio is the measurement of a TVs ability to render it's blackest black and whitest white on a single frame.
And ONLY plasma's can obtain this high of a native contrast ratio. This is because of each one of their pixels can be turned on or off! Creating a wider field of contrast. LCD TVs cannot accomplish this do to the backlight sources. Even the smallest backlight source(LED) covers an area of tens or hundreds of pixels! Rendering their native contrast ratios much lower.
Go with a Panasonic Plasma TV and you will not be dissappointed! Happy hunting!
