ok .. i did some testing with some of my sonys .
- sony pvm 2130 .. 21 inch , scart input , composite , audio etc. nice picture , little geometry and discoloration in tate mode ( same as 2730 ) . u have to keep in mind they there build for hori studio mode use .
- sony pvm 2950 29 inch . modern osd , no noticable difference between hor and verti mode . this thing is huge and heavy . plugged via sub d > 5 bnc rgb connector . if wonna go the 29 inch road its a good choice , but i wont recommend it for cabbing , more the gaming room use . min distance id say 1 meter !
- sony kv21x5d 21 inch , very good osd , good picture via rgb scart
- sony kv25x5d 25 inch medium size , good pic via scart ( my kv25 comes fresh out of my garage .. bought it for 10 euro 1 week ago ) . it can use a little more sharpness . think i have to check the focus .
difference between the studio crts and tv : the old broadcasting monitors have thicker and darker scanlines , compared to the tvs . the tube is extremely curved . modern trinitron tv tubes have less curved tubes / more like the common semi tubes . its formed like a drum/ barrel with flat sides . pro sony : nice ( trinitron style ) contrast and colors . but if u want the perfect geometry u should consider other manufactures . sonys often suffer from different types of geometry problems , but for acrade purpose most people wont even recognize it . i think the quality of a screen depends 1/3 on the the model u use ( quality of tube and chassis ), 1/3 the condition , hours of usage and 1/3 poor or perfect adjustment , cable and software setup. i took some shrinked shots with my cheapass cam .
