HD CRT TV's - I've got some questions!

[Emu Newbie]

Hey everyone,

 

I figured some people out there were using HD CRT TV's (like the later model Sony WEGA's) and I was wondering if you wouldn't mind

shedding some light on the topic for me.

 

I have the opportunity to pick up one of these

 

KV-32HS420 (sony)

 

This is a 4:3 Sony that says it can do up to 1080i, but I guess I'm a little confused as to how a 4:3 does 1080i.

 

I like running my original xbox in 720p with filters on my NES, GENESIS, ETC. and I think it would be cool to keep the Hi-Def output and run those old school systems in Hi-Def.

 

Thanks!
