Hi to All,
Graeme Gill was correct about the Huey on the XL20. This product was
carefully tested on the XL line of products and it is tuned for this
application. I think the XL product line also can be bundled with
specially tuned i1Displays in certain markets/regions. I can assure you
that the decision to bundle Huey wasn't made by some marketing wonk. A
significant amount of testing went into their decision. New test
stations were designed specifically for this technology. They
(Samsung) also invested a fair amount of effort in the software. I have
never used the software , so I can't comment on it. The display is quite
good and it is generally representative of the state of the art in their
technology.
I use a Samsung 243T panel at home. This product had a brief life, but
it is very good for viewing static images. It's response time was too
slow for the gamers, so they introduced the 244 with a much shorter
response time. This had the unfortunate side effect of lowering the
useful field of view and introducing the negative characteristics that
people tend to associate with PVA (variable, asymetric contrast ratio
with viewing angle and position) and increasing cost. I don't think
many readers of this list understand the level of compromise that needs
to be made in panel design. Many of the engineering factors that work
towards a better static display have very negative impact on displays
that need to work well with full motion images. The market size for the
graphic arts /photography is quite small relative to the general purpose
market, so you really don't have many people concentrating on building
the perfect panel the photographer/graphic artist. The internal pipe
lines are also getting complex because of dual link DVI and HDMI
formatting and of course, Digital Rights Management. This is all being
driven by HD video. Many of the next generation displays will have
Picture in Picture capablity where you can show live video on your
screen from a second input. Few if any of these features are desirable
for the folks on this list and they drive the cost of the display up
exponentially due to the bandwidth required for these pipelines. The
end result : panels optimized for still imaging will be more expensive,
harder to get, and the image quality for collaborative viewing will
probably suffer. Vendors such as Eizo and Quato will have to hunt very
carefully for suitable OEM panels and the supply chain will be chaotic.
The DDC situation is simply out of control on all levels: the displays,
the graphic cards, and the operating systems. There are a host of new
commands that offer, in my opinion, dubious advantages to the consumer
and introduce quantum jumps in software complexity. On the other hand,
with luts or gamma control in the display, we don't have to worry about
all the graphic card idiosyncrasies. The problem is that uploading all
this data to the display is time consuming using the ddc channel on the
graphic cards, hence the shift towards USB links (like Eizo pioneered).
This situation complicates third party software significantly due to the
support issues. We now must have software that has to utilize adaptive
strategies based upon the available control set, host interface, and
the manner in which those controls will operate. This is going to put a
strain on many of the smaller developers out there. As you can hear in
the frustration of some of the solution providers on this forum, the
channel conflict between vendor supplied solutions and VAR supplied
solutions is getting worse. Over the next year, this situation will
worsen. Over the next year, we will see more vendor supplied solutions
that don't play nicely with other vendor solutions. That situation is
not going to sort itself out anytime soon. Getting two displays to look
the same that come from different vendors, is going to be harder to do
in the upcoming year.
I get to see most displays before they hit the market and I can tell you
that there will be some great displays hitting the market next year, but
don't expect them to be cheap and don't expect them to play nicely with
one another.... I'm sure the comments on this list will be quite active.
Take care
