I know that modern LCDs aren't the best for old systems, so I've been trying to find a decent one that I can play games as they were intended to look.

I'm looking for a smaller TV (less than 20 inches) that has stereo and S-Video inputs. Sadly, most of the TVs produced in this category seem to either be aerial jack only or mono input only. I'm guessing a Sony Trinitron or similar "high-end" TVs would work best?
