Hehe, I'm going to seem like I entered rant mode again... (yes I know I will use MANY MANY MANY run on sentences in rant mode especially with parentheses.)
I went with the 750p because it had little if any geometric distortion(this seems to be a generalization for good shadow mask tubes, they have good geometry, but lack the contrast, saturation, and sometimes sharpness of aperture grille tubes). I was very fed up at the time with the deluge of 17"/19" aperture grille monitors I checked out (Mitsubishi, Sony, Iiyama, Viewsonic), all of which had HORRIBLE(if the lines at the sides of the image were straight, then the sides in the center of the image were warped! If you set contrast to min, and brightness to max, you could SEE that the outline of the image was not straight and could not be adjusted to be straight no matter what, corner geometry was especially disturbing since few monitors except the Mitsubishi's had controls for those but the Mitsubishi's had dark corners because of the way they got their screens to be flat...) geometric problems. Heck one of the Sony's even developed a "vertical damper wire" type of defect after a few days (this is normally seen in older Aperture Grille tubes, after a FEW YEARS). I'm still convinced that no good 17"/19" aperture grille tubes have been made since 1995. Sheesh...where's the quality control these days...yields and quotas have let too many bad wheels out of the factory...
If anyone has some still sealed in the box Sony monitors like the 420PS from circa 1995, by all means PM me
