Jack,
Samsung put out a demonstration of a DLP 720p and 1080p sets side by side at CES for all the public
to view, 1080p was much more refined and clearer than 720p.
Of course, the comparison has to be made with equal image sources and simultaneous timing, be
geometrically equal and still match the native pixel grid of each set, and the sets receive 720p and
1080p externally, so no scaling or conversion is done on either set, and the view is actually the
image and a set reproducing it. Samsung never disclosed what was behind the sets, but I assume it
was done with care, the visual differences were obvious.
I included the photos of the demo on the report.
I also provided recently a link that showed the differences on picture quality and also showing a PC
desktop with a windows application to note how the increased resolution made small fonts readable on
a large RPTV from the distance.
There is a considerable difference, but to been able to use the fullest of the native capabilities
one needs original resolution as high as the set, and one has to sit closer to the screen to realize
the benefit, the primary objective of going 1080p, which is: increase the resolution to open the
wide angle of vision for a better cinematic experience.
If you are going to buy a 1080p set to replace a 720p set for the purpose of viewing it 20 feet away
from the kitchen to the family room, do your self a favor and keep the 720p set. Unless the
Bloomberg quotes are then readable from that distance and your kitchen is your area of operations
for investments, every one has different purposes.
Upconverting 1080i , 480i/p, 720 to 1080p should not give the same quality of a true 1080p signal
viewed on the same set, if it does something is wrong on the setup, including the viewing distance
and your glasses.
Hi Def DVD is "hoped" to bring that quality, that format would provide an opportunity for anyone to
compare "in the same set and at home" that 1080p original resolution does not look the same than
upconverting/interpolating/inventing pixels of any lower resolution signal to map the 1080p set grid
of pixels. From what I have seen, only Faroudja can claim to come close, and I have seen 1080p from
their expensive scaler since it came out before HDTV was introduced in 1998, using very expensive
CRT 9" projectors, very hi-end dream indeed.
Hugh,
CRT RPTV and FPTV are great for the smoothness they convey on the image, and certainly the best
black of all, but CRT had its time and opportunity to mass produce at an affordable price before DLP
and the rest started to challenge it. Unless you are going for a very expensive setup, CRT never
made it considerably better for the mass than the level of quality you have now Hugh, or also some
9" tube RPTVs.
It is a bit late to reintroduce CRT with 1080p capabilities no one did the effort to reach, and now
much less when every one is moving away from it, the expense of being alone on this dream trip would
be prohibitive to construct and afford.
Joe Kane has been doing great efforts for the last two decades to make manufacturers aware of the
unacceptable design/performance of 1080i sets, and 480i as well, not even with his great efforts not
one regular consumer TV was ever released with true 1080ix1920 capabilities, imagine 1080p.
Also the nature of the CRT animal and the interlace system at 1080i was making the dream impossible.
Except for the recent introduction of the slim tubes we have to accept that this it for CRT in HT.
Best Regards,
Rodolfo La Maestra

Someone suggested or simply declared that the perceived picture quality of
any of the new 1080P sets would not differ from existing 1080i or 720p sets.
Could this be true? To be more specific, a 2004 DLP Samsung or Mits will
look the same as one of their new 1080P DLP's?
