As what size is HD really noticable?

[Batch]

Hi, I'm new here to the forum

I have a small room and only want a 24" TV. I heard that on smaller TV's you can't see much difference between SD and HD as the pixles are compressed. Is this the case with a 24" SD TV, or would i still see a large difference between SD and HD even on something small like 24"?

Thanks

Hi

Well i believe when the EICTA came up with the HD guidelines there was originally mooted a requirement for 26", I think that was dropped.

You will of course see a difference, but It really would depend on how close you're sitting, certainly hi-def material on a 24" dell widescreen monitor looks great, but you are sat about a foot and a half away!


What models where you looking at?

EBU research suggests that at normal viewing distance, HD improvements only become apparent at around the 28" screen size and above.

People don't typically sit a lot further away from larger screens, so the screen occupies more of their field of view, so they are more able to see increases in resolution.

However if you watch closer than the average distance, then you may well see improvements on smaller screen sizes below 28".

HERE is the NON_ HDTV I was looking at, does it look good to you, and what is the average viewing distance, i will be sitting about 6ft from the 24"!

Thanks

I've seen HD vs SD on 26", 32" & 37" LCDs as well as larger plasmas. Whilst the improvement increases in proportion to screen size, it is clearly visible even at 26".

But at what distance away is the difference clearly visible?

The improvement is clearly visible even in a 3" windows when displaying on my PC monitor the HD Forum feed from satellite versus any other channel.

At pretty much any normal viewing distance. In our test room, we're viewing from around 3 metres.

Actually the BBC did the original study and the typical viewing distance was 2.7m (using a sample of BBC employees and the TVs in their living rooms):

The 2.7m viewing distance does happen to hold true in my living room as well. If you're going to be 6ft (1.8m) away from the screen, then chances are yes you would see a difference between SD and 720p HD on a 24" screen.

Ah - but that is comparing sources not displays isn't it? That isn't the same question.

If you fed a standard def display with an HD source downconverted will probably look better than the same display fed with an SD source of the same scene - but that isn't the issue being discussed here!

Thanks for answers so far...

....So what do you guys recon to this non-hdtv? http://www.consumer.philips.com/con...&proxybuster=4BGGZ3RUS2ZHJJ0RMRCSHQFHKFSESI5P?

It has something called crystal clear! How will it compare to a 24" HDTV sitting 6 ft 1.5m away?

 

[m1ket]

if you site 2m from a 26" HDTV and a 32" HDTV both 720p resolution you could argue that the 26" will be better quality due to be pixels being smaller and giving a more defined image...

This has been discussed at condiderable length before. Go to this thread: http://www.avforums.com/forums/showthread.php?t=206217 and start reading at about post number 15.

6ft sems too close to me. What about a 42" plasma, other side of the room surely would save the eyes!

Btw when does anyone think the res of HD would start dropping off in quality ?

I refer the honourable gentleman to the reply I made some moments ago.
