This guy says to go with a CRT for Amiga gaming. His
YouTube vid might be worth a watch:

Yeah that's my video. Not sure if I mentioned it, but the Samsung wasn't the first display I tried either.
I had a 15" ALBA LCD before it, being a cheap display, as you can imagine it looked crap, it didn't even flicker fix interlace modes.
I replaced that with a 19" 4:3 Sony, but never liked the way it looked, I then tried that 22" Samsung, and again was just never satisfied.
Amigas (especially games) just do not look "right" on LCD screens imho.
Now I have my Amiga 4000 hooked up to a 19" Mitsubishi Diamondtron via Picasso IV and my A600/CD32 is on the Philips CM8833-II. Both look streets ahead of any LCD I've tried for the Amiga.
