Hi guys,

I'm looking at buying a 42" Plasma TV, and the one I was looking at says on the specifications that it's maximum resolution is 1024 x 768 but it also claims it will display 1080P??

It has dual HDMIs as well as VGA, so obviously has inputs capable of displaying a 1080 signal.

Does anyone know whether it will do actual 1080? I'm guessing not, but still thought it was worth checking.

You will find it is 1080p HDMI, I saw something like this in my suppliers email.

The HDMI input (Plug) is capable of 1080p but the screen isnt, kinda pointless imo

make and model of tv?
It will prob just handle a 1080i input and rescale to suit the max resolution.
Yy tv has a max resolution of 1366 x 768 but will receive a 1080i signal, but not 1080p

Thanks guys - it was the Senzu that boby55 mentioned. Will be looking for something a bit higher-end!

Yeah it's not really false advertising, it's simply saying if your source device can only output 1080P then this TV will be able to take that signal and display it. However, obviously it will need to scale it down as it doesn't have that resolution to play with, but you will get a picture.

We're moving into a good period for TV's now in that it is affordable to get full HD and also inbuilt Freeview HD tuner, so long term it's probably best to go for a name brand with this functionality, especially if you live in a terrestrial freeview coverage area.

From what i have seen quite a few TVs say they are 1080p capable when they are only 1024 x 768, i think it means that it can display a 1080p signal even though it will only be displayed at 720p

There's a thread somewhere with a battle about this very subject on a CRT, and user dis-pleased with the advertising due to finding CRTs unable to display actuall number of lines.

Bit I digress.

It doesn't appear to be an official standard, however it looks like Pacific Retail and others have adopted the Badge labelling of adverts now. In short..

Badge states 'Full HD 1080ip' - more often than not a full 2mp panel (1920x1080 or similar)
Badge states 'HD Ready 1080i input' - 720 panel, but most likely take 1080 signals just fine (pointless otherwise :) )

Also interesting to note some models will not accept higher than 1360x768 PC input on D-SUB even if they are a 2mp panel.

This is the difference between the terms, HDready or FullHD.

However, HD is officially discribed as any resolution above PAL 720*576(625) or NTSC 720*480(525)

Most displays now can handle a 1080p input, however they scale to the native resolution what ever that is.
So to limit scalling effects you need to match optimum resolutions, 1920*1080 as being the current defacto HD resolution. Some cheap productions have beeen released in 720p or 1080i.

All NZ broadcast is 576i/720p or 1080i, this is a bandwidth constraint

A side note, even 1920*1080 panels and displays scale an image.
The reason is overscan, a method to remove any edge artifacts from an image.
To get perfect mapping you have to achieve 1 to 1 pixel mapping, turn overscan off.
Not all displays can do this, but most have a method now, just their discription how is different on each brand type.

Like the other guys have said it just means the tv is capable of taking a wider range of resoloutions but no matter what you input into a tv it will still scale it to the native res, this will happen with any tv.
A full HD resoloution 1920x1080 on your tv is a nice benefit but on something as small as a 42" I wouldn't worry about making it your top priority.
Tvs with lower resoloutions like the panasonic X10 can still have impressive pictures if you're trying to get best bang for your buck.

Yes good point to remember as sam/others have mentioned, in that ALL TV's have to scale the incoming signal to the physical resolution they have to play with. This has to happen upwards if you want to watch SD content on a full HD set and downwards if you want to watch bluray/freeview TV3 on a SD or 720P set etc. The comment made is just letting you know that the TV WILL accept the signal and display something, rather than not knowing how to interpret it and showing nothing.
