The Dell 2408WFP (A01 Rev) has majorly decreased the input lag from 60 ~ 70ms to 30 ~ 35ms.
That's good to hear. I will try and find a source for this and fix the input lag measurement in the OP.
I have the A01 2408wfp. a cursory runthru of the lagom tests, shows anywhere from 25-60ms lag on the quick response times(grey tones cycling squares with squares). some are close to -10, most are around -25, and one or two in the -60 range of color shift.
i have some contract work due next week so i haven't gotten around to breaking out my digital camera or crt for the ghosting or input lag test. I'm working through the weekend and should finish up next week. i'll post some pics of the tests then.
OK. results in.
on the lagom input lag test. (the clock one)

average is 1 to 2 frames lag for 60hz/fps. so 17 to 34 ms input lag.
Thanks a lot for these measurements. This is uplifting. I will add it to the OP.

This is a calibration/color management question. I have the Eyeone LT colorimeter and I'm using both a CRT and LCD on the same system. Should I use the x-rite software to create an ICC profile? Does a profile actually allow the screen to display more accurate colors/grayscale? I guess I'm not sure what the profile actually does since monitors have their own built-in adjustments as well.
A 'profile' in the strict sense is a notebook of your monitor's physical properties. It records the gamut triangle (the part of the visual spectrum your screen can reproduce) by using the three CIE X, Y, Z ordinates. This range of the visual spectrum is completely irrelevant to the number of colors within that specified spectrum that it can display; that is specified instead by bit depth. (Clearly, bit depth can be up to infinity within any given spectrum, or something like that.) Most monitors have 8 bit depth through one way or another.
Profiles also usually include calibration, which is a list of three columns of 256 values to calibrate each gray level in the display. This is uploaded to your video card to further calibrate the panel even though the monitor does have some R/G/B adjustment.
So yes, calibrate your display and make an ICC profile.
