Is 1080p visibly superior to 1080i with the human eye?
 

I have a 1080p Toshiba 56HM195. From what I can tell (info is scarce),
it won't take a 1080p input over HDMI, the only 1080p I'll be seeing is
deinterlaced 1080i broadcast or cable, which is the default mode of
operation. While it looks good to me, what looks a LOT better is the
native image on either the JVC or Sony 3-chip LCoS sets. I've done a
side--by-side comparison at the store and the JVC and Sony are
outrageous - zero screendoor effect, zero blocking of any kind (even
when standing a foot from the monitor), and no artifacts. They cost
more, but I wish I'd waited and paid for it, they're worth it.

I've seen those LCoS sets in the stores and they look good, but they aren't
1080p, correct?

I think so, too - but they definitely have a superior picture to the
1080p single-chip DLP sets.

In article , says...
Has anyone actually seen a 1080p TV at work? Is the picture really that
much better detectable by the human eye? Do the current HD Channels (eg.
CBS,NBC,ESPN,Discovery,KCET) broadcast in 1080p?

I have a 1080p Samsung and replaced a 1080i Mits CRT RP set and yes the
Sammy looks better. Is it because it is a 1080p set or just that the
Mits was getting soft - who knows. I do like the consistent sharpness
across the screen (no convergence errors either) but the term "better"
is in the eye of the beholder.

You pays your money and makes your choice.

I have seen the LCoS sets, and they have a very nice picture. I don't think
I would be so bold as to state that they "definitely have a superior
picture", I think it depends upon the show you are watching, the room in
which the set is located, personal preference, and various other factors.
Also, an incrementally better picture might not represent a meaningful
difference to most viewers. What I mean is, if you were to assign a
theoretical picture quality value to various sets, and let's say you would
give the JVC 70" LCoS a 97%, the Sony Qualia 006 (1080p) a 100% rating, the
Toshiba 72MX195 (1080p) a 96% rating, and the Mitsubishi WD-73827 (1080p) a
95% rating.

The real question is, would the difference between a 95% rating and a 100%
rating be readily identifiable, and meaningful, to the average, or even
aficionado, TV viewer? In my judgment, all these sets have what most folks
would consider an excellent picture. It probably comes down to price (always
a factor), personal brand preference, availability, features, warranty
coverage, etc. For example, if you intend to hook up a home theatre PC, it
might be more important to you to have a standard analog 15-pin video output
than a 2%-3% difference in picture quality. Price differences are also
significant. I can afford to spend whatever it takes, but that doesn't mean
that I would necessarily purchase the Qualia 006 for $10-12k rather than the
Toshiba for a little over $4k.

All factors considered, I currently lean towards the Toshiba because of its
excellent picture quality, feature set, and competitive price.

The Sony SXRD is 1080p and I see that there is a lot of marketing hype
surrounding that spec right now. Apparently more manufacturers are going to
be introducing DLP's and LCoS sets that can display at that resolution.
Thing is that HDTV broadcasts are all 1080i and will not be 1080p for the
foreseeable future because of the tremendous bandwith required. I suppose
the 1080p will be useful when HD DVD players outputting at that spec are
hooked up to the set. Don't know though if I'll be able to tell the
difference. I'm very happy with my JVC HD-ILA set. Picture is the best
I've seen anywhere.

I did a side-by-side comparison of a Toshiba single-chip DLP set
(62HM195) and a 60" JVC iLA 3-chip LCoS set. The materials I saw were
cable 1080i and DVD of LOTR RotK (played at 480p over HDMI on the iLA,
and in 480p and upconverted 1080i over HDMI on the Toshiba). The
differences were obvious and very visible. The Toshiba visibly
exhibited the screendoor effect on the 1080i cable content, there
wasn't a hint of it in the iLA's picture. On DVD material, the Toshiba
showed moderate blocking, especially in dark gradient areas, clearly
visible at about 2' from the screen, in both 480p and upconverted
1080i. While this level of blocking is not directly visible at normal
seating distances, it causes a noticeable loss of detail. The iLA
showed no blocking at all down to the pixel level. Lastly, there were
obvious artifacts in the Toshiba's picture on the DVD material in both
480p and 1080i. These artifacts were purplish lines betwwen white
gradients, and at edges of color transitions. I reduced the sharpness
to zero on the Toshiba without eliminating the artifacts.

The net effect was not incremental - the iLA had an obviously better
picture at any viewing distance on the same material. My wife was with
me, she could care less about picture quality, and she agreed that the
iLA was notably better. It should be - it cost $1500 more. I have the
smaller Toshiba, the 56HM195. I've spent a number of hours working on
getting the picture quality to its best level (using Avia and other
reference discs). It certainly has a good picture, I'm pleased with it,
but there is no doubt that the 3-chip LCoS iLA set has a better
picture.

Actually, the DiLA would cost me less. I can get the JVC HD-70G886 70"
television for $3800 right he

while the Toshiba 72MX195 would cost me several hundred dollar more.
However, the JVC is not 1080p, and I am pretty much committed to purchasing
a 1080p set. Maybe the answer is to wait until next month when 1080p DiLA
sets are expected, but one can wait forever if one waits for the next big
'thing', as improvements come quite frequently and prices drop.
