I have just purchased an NEC/Mits SpectraView LCD2180UX. I calibrate
and work in cave conditions using an Eye One Spectrophotometer with Eye
Match V3 and I am currently experimenting with the new SpectraView
Profiler 3.03 software.
Something is puzzling me between the different approaches of Eye One
Match V3 and the new Spectraview 3.3 software. The Spectraview OSD
monitor factory brightness is preset at 100%. Eye One match, in similar
fashion to measuring a CRT, measures the contrast and brightness
settings using the Spectraview LCD's OSD panel - Eye One Match
instructions state, "Adjust the luminance of your LCD brightness
control using the OSD, etc, but in the next breath states, "On some
monitors you could use your backlight control".
As there are no hardware controls as such on an LCD I thought the OSD
brightness control was 'the' backlight control?
Using the Spectraview software it can take advantage of using digital
display controls to automatically optimize the monitors brightness,
contrast and RGB settings prior to calibration - a choice I have been
testing. I can see after calibration although the monitors OSD
brightness reading is still sat at 100% the screen brightness value has
obviously lowered after calibration - 85 cd/m2 input.
Are both Eye One match and Spectraview, with its auto digital
optimization facility, calibrating the LCD in a similar fashion behind
the scenes or would one route be better than another in terms of
accuracy, purely in relation to the contrast and brightness settings?
At present I am getting very good colour accuracy and virtually no
banding but the Spectraview monitors tonal range is somewhat flatter
than my CRT. I had thought the LCD contrast might have been still a tad
higher after calibration and would be fighting to pull the contrast
levels down. I am aware that an LCD has black point problems and will
not match a CRT. I would say from testing an Eizo CG 21 a few months
ago the Spectraview 2180 provides similar results.
