Actually, I have this monitor as well, although at the time I bought it, it wasn't nearly so cheap. I ended up giving it to the wife when I got a really great deal on a 19" sony trinitron instead. Although I did enjoy it, but the max resolution is only 1600X1200, and that only at 65 hertz (or is that video card related? I don't think so)
Anyhow, I don't think that Samsung sells their technology to Sony in any way. At least, the tube, which is the most important part, certainly isn't the same. The 955df uses a shadow mask crt, while the Sony's with a Trinitron tube use a flat aperture grill, which is really the best. The only drawback with the flat aperture, at least on the Sony, is if you look very closely on both sides of the screen approx an inch in, you can actually see a very thin vertical black line. This is a wire that the grill hangs from. It bothered me in the begining, but now I can't even see it anymore.
I wasn't aware of the flat aperture grill technology before I got the Samsung, and I think they developed it.
Anyhow, here is a link to some interesting info.
