Yeah, true, but the only 4:3 LCD's out there, were made specifically with PC use in mind, for the most part. I've tried hooking a XRGB2+ to various LCD computer monitors, and it just didn't look right. I'm not saying it looked really bad, but it didn't look quite right. There are also early 4:3 lcd TV's that were standard definition, but again, the LCD quality just wasn't very good back then.
If only you could find a modern day lcd display, with the quality of modern lcd technology of 2013, that had a 4:3 aspect ratio. Unfortunately, I don't know of any. I'm sure there is something out there that could be had, but I'm guessing it would be made for the commercial industry (not consumer use), and would be unbelievably expensive.
