1080p vs 720p
 

I am looking for a smaller HDTV for a bedroom. It seems as though you
have to go at least to a 32 inch set to get 1080p. On a smaller HDTV
(26in. - 32 in.) can you really tell the difference between 1080p and 720p?

To be brief, "no."

No, I promise.

Keep in mind that, when it comes to screen sizes a widescreen inch gives you
considerably fewer square inches of screen space than a non-widescreen inch.
If you're thinking your old 27" set was perfectly adequate, you'll find that
a 27" widescreen looks tiny by comparison. You might then decide that 32" is
the minimum acceptable size after all.

Whats the difference from a 60 inch 1080x1920 display with a dot pitch
of 0.6918mm and a 32 inch 1080x1920 display with a pitch dot of
0.369mm.

The 60 inch 1080x1920 display will look the same at 8.57 feet as the
32 inch 1080x1920 display at 4.57 feet.

Your chart even states optimual viewing distance for 1080i/p is 50.21
inhes (4.1 feet) and for 720p display is 75.31 inches (6.27 feet)

With a direct view panel, my opinion is that the viewing
distance/pixel pitch ratio shall be increased somewhat more so that
the sharp pixel structure in the panel blend together and you can
_not_ resolve the pixels.

If you select the viwing distance so that you can see "all the 1080
details" the picture will not look smooth and natural.

I have my own rule of thumb that goes:
optimum viewing distance = pixel pitch * 4000.
For a 32" 768 panel that means 2m (=6.9').
A 32" 1080 panel (if they exist) woudl give 1.5m (=4.9')

This shall be compared to the chart that uses the commonly used
resolution limit of one arc minute as the optimum meaning that the
pixels in the panel would begin to show up.

It might vary between individuals (and panels) but should provide a
starting point.

Thanks for the replies. The room that the new set will be used in is a
bedroom that we have converted into a computer room. The viewing
distance will be approximately 4 1/2 to 5 feet. At that distance would a
32 in .set with 720 p work well?

It would be too large for me. I watch a 27" at about that same distance.
Before going to widescreen I had a 21" 4:3 analog set. Tried a 25" and
that was too big. Used a 19" 4:3" monitor at 1600x1200 for a while and
that was ok. if going from a 4:3 set that is about the right size now,
just multiple its size by 1.29 to get the perfect wide screen size for you.

I think Wes is very close to 'just-right' and, even 'Goldilocks' would
be happy with his suggestion. We've had some extremes in our guest
room. Guests 'lived' with a 13 inch CRT-SD set for years. 5 feet from
the treadmill and about 9 feet from the pillows on the bed -- too small
for either -- but we prefer that our guests not get overly
'comfortable.' LOL

We moved a 42 inch, ED 16:9 panel in there and fed it with an signal
from an HD tuner. Too large (and slightly coarse.) We then tried a 25"
CRT set 4:3, that had been 'hiding' in the garage. That seems closer to
what's needed for both short-term viewing during exercise (5 ft.) and
steady viewing from the bed at 9 feet.

In some cases, yes, and the 720 looks *better*, the pixel size gets
too small for the current technologies to work well, squeezing too
many on a little screen.

I saw the 108" Panasonic plasma today.

Did not really like the picture quality from anything less than ten
feet. There is such a thing as too big!

All depends on viewing distance.

As he said. And that being said, for almost any probably viewing
distance, the former answer of "no" is correct :-)

The following is often cited:

It states that if you have a 32" set and have normal 20:20 vision,
you will get the full benefits from 1080 resolution from a viewing
distance of 50". Anything above 75" and you aren't even fully
utilizing 720p. My interpretation is that at LESS THAN 75", you
could resolve better than 720p, so there may be some benefit to 1080
at that, or lesser, distance.

I was looking at a 42" 1080p Panasonic plasma yesterday. I don't
think I had to be quite this far away before the hi-res became moot.

The intent is clearly to watch TV in bed. Thus, the monitor will be at the
minimum at the foot of the bed, or 7' away. More likely, it will be around
10-15 feet away. Thus, my original answer of "no."

Even if the monitor is mounted on an adjacent wall instead of the opposite,
it will still be too far away for 1080p to matter, and the viewing position
will quickly become irritating, especially if there is more than one person
in the bed who wants to see the TV, so the opposite wall would be the
eventual home of the monitor.

We really like our 20" Vizio VX20L. Replaced an old 13" Sony Trinitron, so
it was an improvement. The display is 1366 X 768 pixels so 720p is closer to
"native" for this display. I do think that 1080p is way over hyped, but I'm
sure that I will probaly get flamed for this.

Handy chart....
To get a 27" or 36" 4:3 size picture (right column), you'll need the screen
size in the left column.
