Sorry i didnt mean a gimmick as such, i just meant is there a good chance we could need the guarantee.
As for the website it has got a shop but im not sure how to go about proving the price to john Lewis.
Im going to read that AV forums but just wanted to ask one more thing, i've heard somethin about displaying 720 and 1080 and that tellys at the mo are only on 720 but when the real HD gets goin you need 1080 for a perfect picture. Im a bit confused to be honest.
As for guarantee,it's there if you ever need it.If you don't need it,it doesn't matter because it never cost you anything.
As for the pricematch for John Lewis.
Send them an E-Mail giving the details of the shop,ie name and address and the price they are selling at.John Lewis will then someone round to check the price in the shop and availability.If they are happy that everythings above board and correct then you should then get your pricematch.
You'll have to bear with me on the next point.
To get a perfect picture from a 1080 signal you will require a screen that has a pixel count of 1920 x 1080.This means that the signal will fit perfectly to the resolution of the screen.If your screen does not have the above pixel count,then the internal scaler will have to make the signal fit the resolution of your screen.This is where the varying differences in picture quality come from.Some brands have good internal scalers,others don't.
The same applies to 720 signals as well.720 requires a pixel count of 1280 x 720 pixels.
You can buy external scalers that will scale the image before it gets to the TV and these are of a higher quality than the TV's internal scaler,but so is the price,as you are looking at £700 and above for a good one.
You also have different formats with the signals.
there is 720p,1080i and 1080p.
The i stands for interlaced and the p stands for progressive.The best picture at the moment you can get is 1080p,but getting a Plasma that has this feature is more difficult.Pioneer are releasing the first 1080p plasma at a size of 50" but you are probably talking around £5000 to buy.
Here is something I copied and pasted to inform you of the difference between interlaced and progressive.
Interlaced and progressive explained
Interlaced - as used with 1080/60i and 1080/50i (that's what the 'i' stands for) - refreshes the screen in two goes. It changes what's seen on every other picture line in one pass and the remaining lines in the next. The refresh rate will vary from country to country. In the UK it's 25 frames per second and involves, in effect, 50 half-screens per second. The way in which an interlaced signal is handled means that, potentially, there can be problems with rolling lines but usually only in larger displays and even then, that shouldn't be noticeable if the set is working properly. In theory, 1080i may also show artefacts caused by fast-moving objects but until we'd had a lot more time in front of different types of HD footage, we're unwilling to be drawn into the progressive vs interlaced debate.
Progressive - as used with 720/60p, 720/50p, 720/24p and 1080/24p - changes the complete image you see on screen in one go, so each new screenful is, in effect, like a single frame on a roll of movie film. Progressive, theoretically, guarantees smooth-looking pictures because it won't show any rolling lines, nor artefacts caused by fast-moving objects. The refresh rate can vary from country to country and from application to application. AVCHD is able to record progressive at 50 or 60 full frames per second - and we'd expect that to produce very sharp, clear pictures - and also at 24-frames-per-second for a cod film-look mode.
Combining 1080 and progressive promises the best of both worlds - the highest resolution paired with the smoothest picture, so the fact that AVCHD supports 1080 progressive could be seen as something of a coup. Until its announcement, there was little obvious prospect of 1080 progressive being used in the foreseeable future - not for HDTV transmission nor for HD discs. Sony and Panasonic, though, both make HD sets capable of showing 1080 progressive and we see that as another reason why the two companies are introducing AVCHD - to grow sales of these very upmarket HDTV sets.
