Why, in the year 2013 would I be interested in a 4:3 projector you ask ?
Well, it's quite simple. I'm a huge fan of old school, retro video games from the early 1990's. You know, Super Nintendo, Sega Genesis, etc, etc. All of that stuff had a 4:3 aspect ratio. I've hooked up my old systems to my current projector (Optoma HD7100), and they look pretty good, but not quite as good as I would like it to look.
The best possible video signal you can get from these older systems, is analog RGB. You know, the old 15.75khz type rgb signals. These systems had very low native resolution. We're talking like 320 x 220 and stuff like that. My Optoma HD7100 doesn't really know what to do with that signal. Luckily, my Optoma can sync with 15.75 khz, so at least I do get an actual picture. Unfortunately, the projector doesn't really like the 320 x 220 resolution, so it upscales it to 640 x 200, which does create some potential problems for me (I think).
For example, I hooked up my Super Nintendo to the Optoma last nite, and while the picture quality was actually very good, portions of the extreme left part of the screen, and the top of the screen aren't being displayed. On certain Super Nintendo games, this is very annoying, because some of the key health indicators and such aren't being displayed, so you don't really know what is going on. I don't know if the image is being cutoff because of the fact that this is actually a 16:9 projector instead of a 4:3 projector, or because of the strange resolution that the projector is trying to deal with, or because of the timings of the RGB signal it's getting or something. Not really sure. All I know is that the image is slighty off base.
I'm just thinking that an older 4:3 projector, that is more friendly to these strange resolutions would be a good idea.
So, can anybody think of any really good 4:3 projectors that might be more compatible with old school retro video games running at 15.75khz and really low resolutions like 320 x 220 ?
