I really don't expect someone to give a "presto!" answer, because, of course, CRT geometry issues have a variety of causes... but if anyone out there wants to give a shot, would be cool to learn at least.
So I got this Sony pc monitor. It's pretty rare around here to find 21'' PC crts so I got this one for a considerable, "fair" amount of money (so that's why I'm a little bit sad now, because it wasnt that cheap).
Despite being labelled as a "pro" monitor by many nameless people throughout the years on dead internet forums, the geometry on this one is pretty f* up as far as "pro" and "Sony" and "Aperture Grille" goes to my taste. Really: My Shadow Mask 997mb banged up Samsung Monitor has the same "broken a** flat screen" geometry overall (I hate flat screens).
But the biggest issue is... part of the right side of the screen appears to be slightly wider (circa 3 to 4cm from the edge seems to be circa 2mm wider than the rest of the screen, I measured) than the left counterpart. It sounds picky and doesn't seem a big deal, and it's not if you think about it... but the screen is large enough to make it hella perceivable. This basically make the Second player character buff, in comparison to the first player, for example.
Surprisingly it's barely noticeable in shooters/fast scrolling games. It's annoying in Fighting/static games though.
If this monitor was used for "CAD"as they said, then I guess there are houses with bigger bathrooms than garages out there.
QUESTION
I know that the dot pitch is not equally on both sides of a crt screen (every monitor bigger than 15" I have has size discrepancy), and “perfection” is out of question but...
Is there any possibility of a "95% chance" of a bad positioned deflection yoke is causing it? Like, if part of it is uneven with the other? I heard (and when I say heard I actually mean read) that depending of the yoke position the image can be thinner/wider, so I wonder if that’s what is causing it. Or could it be another, almost "impossible" thing to fix (like some IC responsible for the digital image adjustment)? Or at least someone could say “Just live with it. Someday someone will appear in your life and make you happy.” like a hot 60 year old lady who also appears to be tech savvy on CRTs.
Worth notice that no matter what geometry settings (and there are a ton on this thing, including convergence) I fiddle up with, it won't help.
Anyway, thanks for taking the time!
