Revised! 35-37 inch HD telly recomendation!
 

Hi all, looking for some advice on choosing a decent plasma (or lcd or crt)
with HD capability, about 35-37 inches screen size. 2 grand to spend. (just
measured spacefor 42inches and it will over dominate the room!...shame cus
id set my heart on a pioneer 42"!

I have decided on Aego T 5.1 Series...they aren't to big and have had a good
review. Still need advice on an amp though.....

I use sky and have a half decent DVD player.


Cheers in advance!

Steve

I think room domination is a bit of a myth. I have a Pioneer 43" in a normal
sized room and there is no sense of domination. Previously I had a Sony CRT
32" which definitely dominated the room because of the cabinet size. I have
the Pioneer on a wall mount and it can be comfortably viewed from a range of
7ft.

Get the 42", it might look like it dominates the room at first but you'll
very soon get used to it. Hi-Def on smaller screens is of little advantage
unless you sit very close to them.

*Hi-Def* on larger screens is of little advantage because of the compression
artifacts.

Can you back up your statement? Or are you, as I suspect, talking out of
your arse?

Assuming an average eye resolving angle of 0.03 degrees, and assuming a
widescreen 16:9 image with a horizontal resolution of 1920 pixels,and using
H.264 compression (MPEG4 with 8x8cell compression) the following optimum
screen sizes apply. (by optimum I mean the pixel size is *just* on the limit
of being resolved by the eye, i.e. any closer to the screen and you will
start to see jaggies and motion artifacts).

Screen size(inch) 17 21 28 32 36 42 50 80
ViewDist(m) 3 3.6 4.8 5.4 6.3 7.5 9
14.1


And just to make it even worse in the UK $ky has decided to use the 1280
horizontal resolution variant for their *HDTV* offering. LOL! - and with
"optimal" compresion LMAO!

Don't know about you but a 42" screen requires a min 7.5m viewing distance
for optimal viewing which I don't have. A large screen may look good nailed
to the wall but as far as viewing quality is concerned you are on to a
looser.

Following this through for SD (where the pixel width is more than
double), you are suggesting that I should sit over 10m away from my 28"
TV?!

Surely Shume Mishtake!

If you don't want to see any motion artefacts, then, assuming you have
perfect vision - YUP!

Just shows you how crap digital TV is - for analogue transmissions you can
use the rule of thumb optimal view distance of 6 * picture height.

Just shows you how crap digital TV is - for analogue transmissions you can
use the rule of thumb optimal view distance of 6 * picture height.

You set the limit as 1 pixel matching the resolving angle of the eye.
You suggested sitting any closer would not be acceptable. You mentioned
MPEG-4 encoding, but didn't include it in your calculation.

I showed how silly this was by applying your reasoning to SD
transmissions (giving my TV a minimum viewing distance of 10m - clearly
stupid!).

Now you claim it's to do with digital vs analogue. Rubbish! 6 * picture
height _is_ a reasonable rule of thumb, but it gives 1/5th the viewing
distance your original calculation suggests, even before we factor in
the slightly/greatly (depends on decoding) lower horizontal resolution
of a composite analogue signal.

In other words, the often quoted 6H for SD and 3H for HD are reasonable
- your original figures were not.

The reason is that human viewers are more than happy to view images
where the resolution is lower than the resolving angle of the eye, and
this is especially true with moving images.

Of course, you made need to sit in the next room or house or even
street before MPEG-2 compression artefacts become invisible, but that
is a different calculation entirely!

Cheers,
David.
