How, CRTs do not suffer from the main two issues that affect LCD/LED & Plasma, blur & judder.Yes I'm referring to the motion aspect too. It just looks bad.
Counter intuitively the picture with the smoothest motion is the one thats displayed from the shortest period of time. Has to do with the brain's image retention memory. With a CRT you are actually watching a blank/black screen for 80%+ of the time during each frame, but due to the rapid succession of frames your brain perceives seamless motion. The important part is that the blank periods reset the brain's image memory.
Cinema projectors (analogue & digital) use the same principal, as do CMR & FFD, to a greater degree in higher end models. The engineering challenge is to maintain overall image brightness, the brief period when the actual image is shown in each frame has to be extremely bright to counteract the blank/black periods.
