The focus controls are particularly important and often need to be aligned properly for things to look right.
Not all CRTs have manual focus controls,however my CRT does ,I could never get it good as my LCD,I have seen a few AG type CRTs over the years as you know,now I'm talking way back when AGs ruled as the best, and LCDs were still way too expensive and pretty new.
Talking about quality control I have seen a lot of LCDs too ,and the default colour settings,brightness etc are way off ,even my own LCD was way off the mark until I used my ColorVison Spyder 2 to calibrate the colours etc,made a big difference on skin tones etc...
Getting back on topic the thread is mainly about lag,and LCDs have come a long way on response times,anybody that owns a new LCD knows what I'm talking about.
Widescreen models have added an extra dimension to gaming and prices falling all the time is an added bonus,I just hope we start seeing more new quality panels (IPS ,A-MVA etc..) real soon.
