Yes you need to know what you are buying as you may find that you have bought a TV that won't produce what you expect. I think over the past few years lots of people have been caught out by this and bought LCD or Plasma that don't have the correct resolution ect to give you what you want to produce HD pictures.

Look at, "what are 1080i and 720p" take note of the resolution for each and see if your TV comes near to these. yours will more than likely be able to produce 720p and not 1080i.

The best one will be 1080p but this format will be on the newer and more expensive models.

You will find that a 720p produces 70fps and 1080i 30fps so the latter will be better for films and 720p will be used for sports and anything fast moving, so the response time of your TV needs to be low as well.

- Tesco will quite often refund you, because they charge all returns back to their suppliers - put in a complaint to the store, first, if you have a problem

HD Ready > HD compatible

HD Compatible is basically a way for manufacturers in saying... "well yeh, they are compatible with hd signal, but you don't get to operate the HD signal out of box or something".....

My advice, with HDTV's prices crashing down lately, I would suggest that you hold the purchase and buy the one that has been certified as HD-Ready. Less hassle that way.

Thanks for that but cant view the site i am at work and for some reason our network has blocked that page.

I have it connect to mi 360 and i can set the HD display to both 720p and 1080i and you can see the difference from when it is set at 480 so ia m stumpted

Definition OF HD-Compatible from wiki.

"
The fact that a product bears the label "HD ready" does not necessarily mean that it can display the full picture resolution possible from a HD source. Most HD-ready sets do not have enough pixels to give true pixel-for-pixel representation without interpolation of the higher HD resolution (1920x1080) - or even the lower HD resolution (1280x720) horizontally (CRT based sets, or the plasma based sets with 1024x768 resolution).
The term HD compatible is also being used in Europe to indicate that a display device has HDMI capability but with lower than HD-ready resolution. "

Depends on you, but I would rather go all the way and not sacrificed the precious resolution...

Anyway, if you do plan to buy the TV, make sure that it supports NATIVE 720p, some cheap HDTV only have like 480p and 1080i native, and well... that's not very good...

Edit: D'oh, I'm being stupid again. I thought you were planning to buy and not already bought it.

Anyway, it's probably not a dud. Best way to test is to connect a HD source to it. (xbox 360?) If the output looks amazing to you..well... then everything's fine...

HD Compatible - Deceptive label for something that does not actually have an HD resolution, but does have an HDMI input.

HD Ready -

The accepted & official label for HDTVs in Europe.

To be "HD Ready", a TV must accept 720p & 1080i, must have a minimum native resolution of 1280*720, must have an HDMI (or DVI with HDCP) input, and must have component video input.

re tesco passing off tvs. Iv purchased one of their 42" plasmas which they advertise as hd.Iv complained and theres no way after talking to lg about it that im going to accept a refund.Tesco told me it was my and lgs problem.Going to push under sale of goods act for a tv which is as described.If anyone has bought one please contact me.

Tezcatlipoca · 07-03-2007, 22:48

If it's advertised as HD, yet isn't, then it sounds like the retailer could perhaps be in breach of the Sale of Goods Act & the Trade Descriptions Act. Depending on what was actually stated, & how it differs...

Lots of v v useful Sale of Goods Act info:

What model LG is it? And what exactly were Tesco advertising it as?

The pcworld site was referring only to US frame rates. They don't apply in Europe.
For the UK, 720p produces 50 frames per second. 1080i produces 25 frames per second.
Sky and ntl have gone for 1080i encoding, so the best results will be seen on a 1080i screen. A 720p screen means either the STB or the screen itself has to convert to 720p from 1080i, adding an extra conversion stage meaning an additional impact on the picture quality.
