Recently, I purchased a Sony widescreen studio monitor to monitor my Hi Def video productions via component signals. In the past, when I had a CRT Sony studio monitor I would hold a blue filter in front of it and then display color bars and make adjustments to calibrate it. This new monitor has a "blue only" feature on it which would make life easier if this is something that I should still do to it. What I'm wondering is if I still should calibrate this studio monitor in the same fashion as I did with my old CRT monitor. Being that it is an LCD monitor should I still approach it the same way? Does it need to be calibrated?

Thanks...
