What is the official A500+ monitor?

I personally did a small research on this. My opinion is that the Commodore 1084 is the most official monitor for the A500+. However there are so many versions of it!! and I cannot figure out what the differences are and which one of these versions is mostly related the A500+ (since if I am not wrong it was also available for the A500).

I agree that the 1084 series is the definitive "Amiga 500/500+ monitor."  There isn't really a specific revision that is "more correct" than another, though.  As far as I know, no Amigas were packaged by Commodore with a monitor included.  The package deals were put together by the independent 3rd party vendors who usually just included whichever 1084 variant they happened to have in stock at that time.

If I buy a 1084s monitor then what will the picture quality be? Will it be something like this:

It'll be that resolution...  It'll look like looking at that picture through a television, though.   There's some good and bad to that.  

The good news is that the pixels really smooth out in the glow of the CRT, and that resolution doesn't look bad, at all on that size of device.  

The bad news is it would be flickering.  a lot.  640x400 NTSC interlace and 640x512 PAL interlace are NOT easy on the eyes for any length of time.

If it is like the above then would there be any way to improve it?

You won't be looking at it close enough to see the pixelation.  You'll be saying "OW!  MY RETINAS!  THEY BURN!"
