Whats the difference between HD Ready and Full HD

The last time I viewed one, it suffered from ghosting. Obviously things have moved along since then.
When the OP wrote of HD Ready, it put me in mind of old technology.

Im not fussed personally as im quite well up on tv technology. But why post to not get a plasma to the OP knowing your information could well be (and is) incorrect?
Ghosting is unlikely to be lag on a plasma, what you saw was probably very poor interpolation, or some other form of picture processing

I didn't know. Don't be silly. I went on my former viewing. Reading this thread has brought me up to speed. I'm not up on my TV technology.

When I'm ready to buy one I will swot up.

Difference on LCd and Plasma

Lcd, Liquid Crystal Display, are television sets that use LCD technology to produce images. LCD televisions are thinner and lighter than CRTs (Computer monitors ect,)

plazma- called that because there displays because the technology utilizes small cells containing gases in the tele,

Own plasma me self used to have problems in the past but plasma is good the best way to determine is examine the picture! Turn on the television and off see if you have any glare or resulation of the old picture, When a plasma has been on for some time and you suddently turn it off from the raido station ect it sometimes you can see the graphics of the station on the screen and take a some time while the television cools down,

BTW all Plasma televisions now come with freeview built, Dont worry about it being HD ready or Full HD-There the same still need a HDMI cable to get full 1080 signal on the television anyway

Hope that helps

Not only is this almost unintelligible, it is also nonsense.
There IS a difference between HD ready and Full HD. Read the screen resolutions on Amazon for the two specs.
720 pixels HD ready, 1080i pixels (interlaced. Scan one set of pixels on one cycle of mains, and the second set of pixels on the second scan.) & 1080 pixels full HD. (scan all 1080 pixels in one scan.)

I've got a 42" full HD panasonic plasma, I'm very pleased with it. I was always under the impression that flatscreen TVs had poor picture quality, I now realise it was just that the one's I'd seen round other people's houses are just cheap crappy ones, good quality flatscreen TVs have a much better picture.

Go and have a look in the shop to see if you prefer plasma or LCD, they are a bit different. To me, the colours on a plasma look much 'richer', and the blacks look black, whereas LCDs look washed out and the blacks look dark grey. But some people think plasmas look too dim, and that they prefer LCDs because they are brighter. So it's probably just personal preference. Do bear in mind that when you look at them in a shop, the room will probably be a lot brighter than you living room where you watch TV.

many a true word !

Lots to talk about here.
Plasma: Excellent reproduction of almost all colours. Able to change the picture very quickly without blur. Virtually no burn in these days. Higher power consumption. Heavier screens.
LCD: More difficulty in producing deep blacks. Higher maximum brightness if working in daylight, but still less of a range of colours and greys than plasma. Not able to change the image as quickly as plasma (whatever marketing terms the manufacturers may use), so potential for blurring of the image, for example when watching sport, or other fast moving scenes.
LED refers to an LCD screen with LED backlighting. They used to use a fluorescent light at the edge of the screen. The pixels would turn clear to let the light out, or solid to display black. Since the pixels could be neither perfectly clear, nor perfectly solid, it was hard to display an image with both light and dark areas - the earlier mentioned problem of dynamic range (black-to-white range). By putting multiple small LED lights behind the screen, it is possible to dim the LED where the picture needs to be dark, and go full bright on the LED where the picture needs to be bright. Still not as good a solution as plasma though.
LCD screens (especially with LED backlights) can be thinner, lighter, and use less power.
In my opinion, the best plasma is clearly better than the best LCD/LED.
That's the screens. Remember also that half the end result is down to the processing. How does the set take the incoming signal and fit it to the screen. If you are mostly viewing Freeview, the set has to roughly double up the picture to make it fill all of the available pixels. How it does this can make a huge difference to how good the end result looks. Generally you get what you pay for. The more expensive sets have much better processing.
Now on to resolution. It's a game of diminishing returns. If you are sitting very close to the screen, you might be able to make out the individual dots that make up the picture. Once you get further away than this, it becomes of little or no importance whether your screen is 720 or 1080 lines. You may feel the need to get a 1080p TV so you can tell your neighbours you've got one, but if you do a controlled test - ask people to judge picture quality of multiple sets - the results do not depend on resolution.
You need to think about what you watch, and what you plan to watch in the next few years. Blu-Ray DVD, Xbox, and some files you can download to your computer can be 1080 lines. Other HD sources will be 720p. Freeview is 576 lines.
Progressive/Interlaced. That's the p or the i at the end of the 720p/1080i. A progressive picture is captured and displayed in a single image. Think of it as starting at the top left, and progressing to the bottom right. An interlaced image is more complicated. It is made up of two half-images. Imagine a 1080i image. Line 1 is drawn at the top of the screen. Then we skip a line, and draw line 3, then 5, and so on until we reach the bottom. Then we go back to the top and start again. We start with line 2, then 4, and so on until we reach the bottom. The two half-pictures make up one complete, high resolution image. If we are viewing a stationary or slow moving picture, this results in a high resolution, high quality picture. If, however, there is fast motion in the image, we could run into problems. In the time between the two half-frames, a football could move its position. So instead of a single, round football, you get two dimmer, less round footballs in two different locations. It all happens pretty quickly, but it does diminish the picture quality. So, if you are watching a nature program with huge wide panoramas, you might prefer to use 1080i. If you are watching sport, it might be better to go with 720p - you give up some (very fine) detail, in exchange for a faster refresh of the image. Why not 1080p you ask. Well, that's a lot of imformation to broadcast, and a lot for the TV electronics to swallow, so nobody is broadcasting 1080p yet.
How to choose. It's tricky. Just going into a shop isn't going to solve your problems. They normally have the brightness wacked up to maximum to make the sets stand out. That's not how you are going to watch it at home. It also makes the LCD's look better, as they can normally go brighter, and it hides their poor black reproduction. What you can learn in the shop is how good the processing is. Look for motion blur in fast moving scenes. Look closely and see how much changing is going on in what appears to be a static part of the screen. It almost looks like ants crawling on the screen to me. Be sure to look at some Freeview if you like to watch that - it's no good buying a set that plays a Disney animation beautifully, if it's terrible when fed with a standard definition source (some of them are).
Read up on the internet - AVSforum.com is very good.
Make a list of the sources you are going to connect to the TV, and make sure the set can handle all of those inputs.
If you are going to listen through the TV's speakers, have a listen to those before buying.
Hope this helps.

Some absolute rubbish posted on here, with the corrections struggling to keep up. Plasma, lag?!
If you read only one post, read AlwaysSomething's above.
Anyway - you've got Sky HD - UK HD broadcasts are in 1080i, I'd suggest that you therefore want a Full HD Ready screen, 1080p, instead of just a 720p set, where the picture will be downscaled. Make sure your Sky Box is set to output 1080i. I prefer plasma for the black levels, movement and vibrant colours, LCD has got better here as a technology but I still think plasma is better. Make sure you're not comparing a cheap TV with an expensive one, everyone bangs on about LED TVs, but a cheap one will still look hopeless compared to a decent, modern branded one.
You should be able to afford a 42" Panasonic G20 plasma TV (about to be replaced with the G30, but not much difference IMO) for your budget.

If your referring to my post I can post a link to show a Panasonic plasmas poor input lag

If not, forget it

Nope, was in reference to post #6!
