In the main, 90 degree deflection is for small screen sizes up to 20". For the larger sizes ie 22" and above, 110 degree deflection is the norm. An exception is a 20" version of both 20AX and 30AX CRTs.
Of course. 110 degree deflection in monochrome CRTs was around long before colour CRTs adopted this approach.

Doesnt a certain degree deflection give x-rays when set up in a certain way?
Do different degrees give a different picture quality, or give any improvements other than size difference?
Why didnt colour sets start with 110 degree deflection CRTs if they already existed?
Thanks
