Ive just swapped out my old NEC 1550V 15" TFT for a pair of NEC's 1550M 15" TFT's and the difference in picture quality over the older 1550V is amazing

Now my picture is really sharp, whites are white, not the old off white due to the dimmer back lamps. Colours are so true that my Iiyama 451 19" CRT is redundant

If any of you guys are rooting through this thread and looking for a great TFT i would highly recommend the NEC 1550M.
My old 1550V had a brightness of 200 cd/m2, contrast of 300:1, 30ms pixel refresh (black-white-black).
The new 1550M's have a brightness of 300 cd/m2, contrast of 450:1, 25ms pixel refresh (black-white-black).
One thing i also noticed about the 1550M is that if i open Media player and try drag it around the desktop i cannot get it to blur no matter how fast i drag about.
Funny thing is the pair are running off an Elsa GF2MX PCI Twin head with Analogue inputs and the sharpness of txt etc is superb.
I have seen TFT's running DVI before so am surprised how this Analogue input can be just as good IMO FWIW.
Hope this info may be of some use to somebody.
