Umm not sure what you are saying here. The BEST hands down display for a classic amiga is a 1084 monitor with RGB. This is what all the games and demos were designed for. It has rich color depth and scanlines. I'm lucky i have a Sony 20" broadcast video monitor that does both PAL and NTSC and is RGB ( I have a modded cable for amiga)
I think you misunderstood. On 1084s that have both digital RGB and analog RGB ports - the 2 big round ports next to each other, as pictured above - analog RGB is the correct port. I think the digital RGB port was meant for CGA video from Commodore PCs.
