Although I agree with the basic objective of the article of making people cautious about high
resolution claims, I have to say that this is a low blow by this writer singling out Hitachi.

He obviously does not know, or does not want to say, that Hitachi is being using their Virtual HD
1080p video processing circuitry for a few years already, way back, much earlier that any of the
recent Holy Grail claimers of 1080p display capabilities.

Hitachi never intended to mislead the public in making a consumer believe that their sets display
1080p resolution, all their specifications are very clear and honest since day one, for anyone that
cares to read.

They offered a full explanation of how this Virtual HD processing works, which precisely should
avoid accusations of misleading the reader about the actual resolution of the TV after a signal
passes thru such Virtual HD 1080p processing.

In other words, Hitachi has chosen to elevate the internal scaling and video processing of input
signals to 1080p to adapt to whatever the display is designed to display on its screen. I see
nothing wrong with that, it is a choice of internal video processing that the company seems to find
more beneficial for the final quality of the image.

The 1080p spec catches the eye of course but no one put them against the wall a few years ago when
they introduced the concept, why now? because all the others are playing the 1080p display game and
this suddenly might be interpreted a sneaky spec? Sorry, but too late to corner them for that.

What about all the 1080p sets that do not accept 1080p and they do not say it? or the ones that
deinterlace 1080i video as one 540 field per 1080p frame? They should be against the wall first
because they do not offer any explanation of those "features" as Hitachi does.

I always feel sorry for the consumer that is not well informed or is intentionally misinformed but
over the last couple of years most sets have clear specifications of the resolution they display,
especially LCD and plasma panels showing the pixel grid spec on most floors, and most other HDTVs
are now using DLP, LCoS or LCD chips with fixed pixel grid as well. That is a clear indication of
the resolution of the display device.

HDTV was very complicated to understand by a 1998 early adopter, but is now getting much better, and
consumers have a better chance to buy intelligently if they care to research a bit what they plan to
buy, starting by the fact that most magazines talk about HDTV all the time and most people use the
internet to find better deals all the time, and that is also a source of valuable research
information if one uses proper care leaving out the weed of the zoo.

If even technical people have trouble knowing if sets can produce HD
how can the normal people figure it out? The link below is from a
review site (a very good one) that recommended a set for 1080p display
and then later realized that it can't do it.

Bob,

It is not only about the level of black, ii is also about how the various black textures of
different black objects grouped together within the same area of the image loose individuality on
their patterns.

Such as the threads of black hair of an older person that has other tones mixed with it (gray hair
anyone?), and that hair is at the foreground of a black linen curtain that should show other
texture, and by its side is the glossy lacquer of a black surface, etc, etc.

In many cases such conditions are displayed as a loosely defined mass of even black, in other words
the black of the hair continues over the linen and the furniture and so on.

I am glad Ken provided some inside from a calibration stand point, perhaps he could expand to cover
your comment about black.

Best Regards,

Rodolfo La Maestra

Yes, LCDs not only have trouble showing a true black, they have trouble
showing black detail. As a result, their pictures often look flat and
two-dimensional, although they also look bright, sharp and colorful.

My own rule of thumb for LCDs is this:

A gym, a daytime family room, a kitchen? LCDs are great. A HT room, for
serious movie watching? Several technologies are better at this point.

Black is perception, I can make anything appear black by increasing the
light around it.

The biggest problem with LCD black has been the lack of a brightness
control for the lamp to match the viewing environment as well as a black
level control to set the cutoff point for the signal. No brightness
control is one of the problems with my PC LCD monitor which causes it to
bury blacks.
