Not a 3D one?

Anyone know what the HD staus is with 3D or does it not have one seen as its supposed to be more real life?!

3D as a feature is independent of HD. You could have 3d on a non-HD set technically, though in reality all 3d tv's to my knowledge are HD and at least HD Ready (720p).

As for Full HD vs HD Ready that refers to Ready (720p) and Full (1080p). That is purely a description of the resolution, and specifically the number of horizontal pixels that make up the image.

In my experience at 32" at usual viewing distances the difference is barely noticeable. Bigger sets 37", 40" etc it becomes noticeable and I'd not buy a 50" (well I'd not fit it in my lounge but besides that) or bigger without going Full HD but thats just an opinion.

It does depend on what sources you have (eg Sky HD, Games console, Blu Ray etc) and what you mainly watch. For example if you mainly watch enders and corrie I don't think the extra resolution will matter much. But if you watch a lot of sport and blu ray films, or Sky HD films then it can matter.

I have a 3d tv that I bought 2 weeks ago and whilst the 3d is a good novelty, the 2d 1080p picture is absolutely stunning and I'm delighted with it. Best picture you can get for under £700 I reckon!

it's the vertical resolution - TV has been just about always characterised by line count e.g. 405 lines and 625 lines. Those two were both interlaced.

Oops yes sorry a typo there!

Correction: Horizontal resolution re 405 & 625 lines. Interlaced?? Pixels are resolution in the vertical plane. 720 or 1080 pixels per line.

Perhaps you don't know the difference between vertical and horizontal - horizontal goes across and is a line in TV parlance.

The first poster made a typo. You seem to be completely confused. 720p is 720 vertical pixels and the equivalent of 720 lines (apart from the red herring of interlacing) etc.

720p = 1280x720px
1080p = 1920x1080px

Some 720p LCD TVs may offer slightly higher res - typically the smaller 720p ones which will be 1366x768px as that is a standard resolution used for computer monitors.

Hd ready with lower than 1080 is more like DVD quality,

Is incorrect.

720p is the format that Sky and Virgin Media use on their HD packages.

There is also a thing called the Lechner Distance Chart. This uses the resolution an eye can perceive to tell the differences between resolutions based on screen size and viewing distance.

To notice the difference between 1080p and 720p/1080i on a 42" TV, you need to be sitting at 5.5ft or closer. The smaller the TV, the closer you need to sit.

Bear in mind the average viewing distance noted on a BBC White Paper on this was 9ft. Most people are not getting the full benefit of the 1080p TVs they bought...

Having 1080p compared to 720p (both high definition), is like having a camera with more megapixies. The more there are, the better the image quality.

HD ready is a certification program introduced in 2005 by EICTA (European Information, Communications and Consumer Electronics Technology Industry Associations), now DIGITALEUROPE.

There are currently four different labels: "HD ready", "HD TV", "HD ready 1080p", "HD TV 1080p". The logos are awarded to television equipment capable of certain features.

In the USA, a similar "HD Ready" term usually refers to any display that is capable of accepting and displaying a high-definition signal at either 720p, 1080i or 1080p using a component video or digital input, but does not have a built-in HD-capable tuner.

I've got an 84" 3D Full HD truecolour display.

It's double glazed too. Only problem is the programs are boring and only beat 50% of the normal broadcast stuff. I do particularly like the grass growing program.

I do hate posts like this, when flippant comments are made - "grass growing" programme indeed !

You obviously haven't seen the paint drying series (26 episodes - follow up planned already) - absolutely superb, you can almost smell it !

My understanding is that there are different standards and measures on the distance required to notice the difference and to some extent it revolves around personal opinion.

I know what you're saying but my relatively well sighted Mother cannot tell SD and HD apart on my 40" TV. Genuinely cannot. So the difference between 720p and 1080p even from 3ft away would completely go over her head.

I think what I'm saying is that there is as you say a supposed measure and standard of what differences the eye can see based on resolution and distance but there is definitely a personal element to it as well as the absolute "measured" value IMO!
