[Tig] another new monitor? (could be a sony-beater?)

[glenn chan]

Isn't the Barco monitor the same RHDM-2301 that they were showing at NAB?

Here is the Barco website's product page:

I was told that the scanning LED backlight is designed to emulate the
CRT motion characteristics... but it doesn't seem like it.  The CRT
has an electron beam that moves extremely fast and it has its own
characteristics (eye strain, flicker higher in peripheral vision, how
annoying the flicker is depends on phosphor decay, etc.).  The Barco
website doesn't describe their technique, but my (wild) guess would be
that they are using the scanning backlight technique described here:

2- I think some of the motion characteristics of new display
technologies is getting very... weird.  And we don't yet have
standards on what the motion reproduction should be for reference
monitoring (it's being worked on right now).  To my eyes, the high
framerate field emission prototype I saw at NAB had very nice motion,
while all the LCDs I saw had a motion artifact of some sort.  For one
120hz product, black frame insertion flickers for white highlights on
a dark background.  The Barco has a slight flicker to it.  Without any
of these techniques, the LCD has slightly blurry motion... but to my
tastes I prefer that over any flicker.

As far as ghosting goes, some LCDs can do weird stuff.  The screen on
a PSP (playstation portable) looks great from white<-->black
transitions (and games with very saturated colors), but moving flesh
tones on a dark background looks absolutely terrible as there's color
shifting on the flesh tones.

And then other technologies like 1-chip DLP and some (but not all)
plasmas have weird artifacts (e.g. DLP rainbows).  So it raises the
question... what should our monitoring practices be?  What should the
standard be?
IMO, a reference display
[A] shouldn't have any overly objectionable artifacts... e.g. flesh
tone color shifting, 1-chip DLP rainbows
[B] let the user spot motion problems such as judder and flicker (e.g.
flicker from bad fluorescent ballasts).  Also need to spot content
that might introduce seizures (it's happened before).
[C] Otherwise don't worry about motion reproduction differences
between displays.
