This is probably a daft question, but I won't know unless I ask, and my curiosity has gotten the better of me so here goes.. I was reading another thread and someone mentioned the Barcos have their tubes the other way round to other CRTs (RGB instead of BGR I think). I then started thinking about the colour balance across the screen and how most CRTs fix that with modulation, but what of you stacked two identical CRTs so that one was RGB and the other BGR - would that help in any way? Would it help non modulated models, or would it just make matters worse as the colours were now being mixed R/B on the outside? I guess that would be a daft way to do it as one would be ceiling mounted and the other floor mounted. Would that help in the same way a Torus screen can help though?? The gains probably aren't worth the hassle but things like this make me think about different ways of doing a job so wondered if anyone had tried it and what the results were. Also - can you swap the red and blue tubes in a CRT so they go from RGB to BGR and do things still work the same (swapping red and blue component cables over as well? Obviously s-video and composite won't work) or is there something else involved? I'll get me coat.... Gary.
