There are many almost free old CRT's that would match a SNES in resolution.
What do you think of a 4:3 screen around 50" with R G B interlaced from a SNES?

Abit too small mate, youll have to go about 70 inch or so to get focus. But itll look good, i use my two CRTs for retro gaming all the time.

trust me. You will not like 480i interlaced on a CRT projector Unless the tubes are very soft or you purposely defocus, the lines are crazy huge with very obvious space in between them. Over time I have seen 480i line burn, and it can happen in only a couple hundred hours on a EM set.(saw this on a G70,XG, and BG808 among others) I use a old BD500 (7" ES tubes) for my older videogames (sega,NES,SNES ETC.) and it looks OK but I prefer a 25-27" CRT direct view tube for 480i. Some processors will have special frame doubled 480i mode that works quite well. I think their was a long thread about this over at AVS in the processor section a few years ago that specifically went over this, you should be able to find it by searching. Some processors also have a RGBS interlace 480i input that can be doubled or frame doubled but only a few specific models have this. I remember a older Faroudja was one of them.

On the size issue. Some Projectors can do as small as 40" with certain lenses. Corner focus can be a problem. The toe in angle for the tubes can be a problem and can strain the convergence electronics some. I had my barco BD500 with a 50" screen and it worked well with the noritar 14x lenses but not so well with the HD145's at that small a screen.

Ok thanks for the info! i think i go for a 29" trinitron crt from sony

[Jeremy112]

and not true on the screen size, you could go down to about 50-55" with a CRT projector, Ive done it with the Sony 1272Q and my NEC 9PGXtra with the HD-145s. Ill admit that 50-55" is the MINIMUM I could go to get it focused, it was very slightly soft but it was still very clear and sharp,

but they are right, 480i on a CRT PJ is terrible, its like looking through windows blinds, I would think if you wanted to scale the signal from the SNES to something higher that a Video Processor or Line doubler, etc could help with that (thats my plan for my vintage games)

I have a 27" trinitron I use for our 8-bit Nintendo and it looks great!

I know the mame arcade emulator has some of the nintendo games in it. Also it will do some sort of classic screen emulation to put in the lines and make it look more authentic. Of course you'd be playing the games from a pc then, not the real nintendo.

Hey i found a guy who lend me a Sony 29" 100Hz with scart(RGB) input

What is the main difference between an RGB-TV and a real Arcade Monitor with RGB + composite sync?

[KrisRoberts]

I used to build scart->rgbhv adapters for the ps2 and Xbox back when I had a vph-1040 projector. You had to use a little IC (LM1441?) and a simple circuit to get the sync off the green signal. I imagine you could do the same thing with a scart adapter for the snes.

arcade monitors are 15khz progressive low resolution large shadow mask sets. The sony uses trinitron type shadow mask and will not give you the same look or sync as a arcade monitor. You may want to to do a google search for arcade monitors wells gardner I think are the most popular and a complete writeup is available on their site describing the differences.
