For sale here is a small but excellent Samsung. The dot pitch of 0.28 mm is good for its size, and 61 kHz isn't bad either. To be honest, I don't know enough about 15" CRT monitors, so smaller ones, and I have very little experience. If you have any questions, I'd be happy to find answers. Otherwise: New in box. Never used, never unpacked. I can't say much about it; the box doesn't have the best smell from the previous owner's storage. But of course, new from a brand like Samsung is very, very rare. If it doesn't work, you get your money back.
