My Viewsonic A90 is dying on me and I need to pick up a new CRT that I use for my 2nd monitor. I found someone on craigslist selling an A95f for only $20 that I'm planning on picking up after work. Is there any noticeable difference with these stats? A90: http://www.viewsonic.com/support/crtmonitors/a90/ 0.23mm horizontal dot pitch 0.27mm diagonal dot pitch A95f: http://www.viewsonic.com/support/des.../aseries/a95f/ 0.25mm aperture grille [at center] 0.27mm aperture grille [at corner] All the other stats are pretty close besides refresh rate, it just seems the dot pitch is different? Dunno what this means though. Also anyone know what the 'f' is for, I'm pretty sure I have an A90 at home but it could be an A90f.
