1024 x 1024 ??

My Philips TV

has always been described as 1024 x 1024 - but this implies it's square monitor but you can see it's 16 x 9

Wassall that about - Is it a printing error?

Only if you're implying it has square pixels.

It's entierly possible that it doesn't, although oddly the panel is also described as WXGA which is typically 1280x768 or 1368x768.

Do you think it's a typo?

If the pixels were oblong the picture would still look squashed - err - wouldn't it?

Not necessarily, it could use something similar to ALIS to give the quoted 1024x1024 interlaced resolution.

No, I don't see why? The image would be scaled by the TV to display appropriately on-screen.

A pixel doesn't have to be square and a TV won't necessarily map pixels on a 1:1 basis.

No, it's quite common for plasmas to use non square pixels.

You have to realise that pixels in the video stream rarely map onto pixels on the display on a one to one basis. Even when the video resolution exactly matches the TV resolution there will often be overscanning.

1024 x 1024 using non-square pixels, just like the 1024 x 1024 ALiS panels from Hitachi.

it's probably the same panel then (albeit in Philips TV) - i'm happy with mine

just thought it seems unusual to have square resolution on 16:9 monitor - apparently not

It is unusual, but then ALiS panels are quite unusual in that they are interlaced displays.

1024 x 768 is a very common resolution on progressive plasmas (4/3 pixel ratio on a 16/9 display).

The only problem with non-square pixels is when hooking the TV up to a computer. Windows assumes pixels are square.
