Sorry if my language wasn't precise enough. I think of gamma as everything
between black and white, so if the gamma is bright I mean that the midtones
appear brighter than they should to me (lower contrast). I mentioned a gamma
of 1.8 as approximate, because it seemed about as off as uncorrected Mac
desktops do when looking at PC graphics, for those familiar with that issue.

We went in single-link HD-SDI 1080psf23.98. We fed it from a Mac with an AJA
Kona 2 card. The files played were AJA Kona 10-bit RGB quicktimes,
uncompressed final output from some features we colored. The signal was
simultaneously being displayed on a JVC DT-V1950CGU CRT monitor so we could
be sure it wasn't a signal issue.

We did calibrate the JVC LCD monitor using pluge, bars, and blue filter. We
did not put it on the spectrophotometer or use a 3D LUT profile for it
because that wasn't the sort of thing we wanted it for. We were looking at
it for editorial monitors, where we don't expect the editor or editor's
assistant to do much more than show bars and adjust contrast (blue only
adjustments if we're lucky :)
