LED is much sharper than LCD and Plasma?

[rikky]

there's so much conusion in the display market.

firs tthe came up with this concept of "hi-def" which was just the umbrella term for screens with slightly more dpi than standard displays.. hidef could be used for both 720p and 1080p and more.

Now this one is even more confusing and for a while it got me. Most LED displays aren't really LEDs, they're LCD displays with LED backlit..


The market is going to get really confusing when true LED displays become affordable and minstream

Most of the LED TV's are not even backlit - they are Edge-lit to save money ...

Once true LED displays are released possibly this year they will be known as OLED so shouldn't be too confusing ... but they will be megabucks.

Ok so from reading through these posts am still not much the clearer which is better, I suppose thats because each technology offers different features etc.

I just want a really nice razor sharp image,with a 47"-55" screen for bluerays. should I go LCD plasma or LED ?.......... Confused to go 3D or not!

I have £900-£1200 to spend -

Ok so maybe not the AV specialists like Richer Sounds and the like but i know someone who worked in Curries. I went in there to look at a panasonic TV and the picture was crap. I asked him about it and he said it had a poor feed and the one that looked the best earned curries the most cash.

Might have changed though since 2 1/2 years ago

So what he was saying was that people bought the TV with the best looking picture...Well that's not too surprising is it And ad a consequence that TV generated the highest turnover of all. Again that's not exactly a revelation either. lol

Not to pick at your post as you obviously know your stuff, but don't all modern sets have that 'demo' mode that you have the choice of running when turning on for the first time?
This basically ensures the manufactures the brightness is whacked up for them!

Feel free to pick away. It's useful to dispell some of the myths surrounding retail.

Some sets do have demo mode. It's the contrast that gets whacked up. The brightness is usually turned down to make blacks look blacker and emphasise the difference ( contrast) between dark and white. Colour balance is skewed towards a heavy blue tint; again this is too create the impression of searingly bright whites.

However, TV manufacturers generally ship with the default setting as Dynamic. This also does most of the above. In the world of shop floor TV demos the set that "shouts" loudest is the one that attracts most attention. Sadly its rarely the best set to buy.

The reason for shipping in Dynamic mode is simple. The chances of anyone doing more than the basic plug in & tune in when unpacking a TV on a shop floor are slim to none. In fact, the lack of hands on experience on the shop floor is scary. Most of the big retail sheds the staff are there to merchandise (stack shelves, keep promotion PoS up to date) and take money. They are rarely given the opportunity to get to know the products beyond the very basics and a few techie sound bites. So many times I have seen, heard or been told of sales people reading off the shelf sticker when asked about product features. You may know someone who has experienced the same. The exception is with cable sales where the stores heavily focus on margin makers.

What you are seeing is "PWM noise" and quite normal on plasma tech - you will only see it close-up as you say and not at normal viewing distances.

With the 2011 Pannys - or at least with the 42ST30 which I just returned and the G30 I saw in the shop - the dithering is noticeable at 3 to 4 meters in dark scenes.
