Hi all,
I haev been wondering with the current technology,
what is the smallest in inches/centimeters that will
display an hd image 1920x1080i so that a human
can see the "full" picture?

What the human eye can see is relative to viewing distance. Currently,
the smallest CRT (DirectView) set available capable of 1920x1080i is
30". For CRT RP I believe it's 46". Zennith/LG makes a 17" widescreen
LCD HDTV/Monitor capable of displaying 720p (actual: 1280x768 native).
Nothing smaller than that capable of displaying "full" HDTV as far as I
know.

Most computer monitors are capable of HD resolutions. I have a 19" Viewsonic
CRT that is capable of a 1920 x 1080 resolution. Computer monitors will only
use RGB, so you might have to convert a Component type signal to RGB.

what brand/model? competitors? Is there much difference in picture
quality between the lowend brand and the highend brand?

I doubt if your 19" monitor can actually display 1920x1080 pixels. If it
did, you would need a magnifying glass to see them. An HDTV image will
notheless look quite good on a 19" or 21" monitor.

Sharp LC-45GD4U 45" LCD HDTV. It actually has 1080x1920 pixels. (about
$7000)

The monitor that I read your post on is a 19" Viewsonic P95f+ (~$300).
It is configured at 2048x15360p at the present. I use four xterms with
113 rows and 80 columns tiled across the full screen. The text is very
crisp.
It can easily display a 1920x1080x60p image.

I'm afraid it can't.
The aperture grill on that model is .25mm at the center and .27mm at the
sides. The visible image is 18" diagonal, which results in 365.76mm for
the horizontal width. Even with a .25mm DP across the entire display,
the maximum resolvable pixels would be 1463 on each horizontal line,
and about 1097 distinct scan lines. For a 16:9 image, it could only use
823 of those scan lines.
1463x823 != 1920x1080
I've been down this road before a lot, and I'd go nuts looking at the
fuzzy image that must result from 2048x1536 on a monitor that can only
resolve about 1300x975.
There's a reason that monitor only costs $300.

My expirence is in violent disagreement with your calculations. I have
no problems with 320 14 pt characters and 4 sets of xterm borders in the
2048x1536 setting. The characters are very sharp, if tiny.
Additionally, I have two other, larger (22" and 21" ) Viewsonic monitors
that do provide visually sharper characters in 2048x1563 mode than the P95f+

I'm not sure what font you are using, but I don't have any that have 6
pixel wide character cells when rendered at "14 points". I have to drop
to 7 point fixed pitch fonts to get that width. Also, a 14-point font
results in 5.14 lines/inch vertically (with no space between lines), or
only 55 or so lines of text on a 18" visible diagonal monitor. 113 rows
means you need about a 6-7 point font. Something tells me you use that
setup for watching output from programs, and not for editing text.
Regardless, you still can't resolve 1920x1080 at full resolution, and it
*would* look fuzzy to me. I had headaches for the first week I got my
17" 1280x1024 LCD, and again when I got the the 20" 1600x1200 LCD. The
image was so much sharper than before that it was almost to the point of
annoyance, but it's now the standard for what I expect from a monitor.

This makes sense and proves my point. They are physically larger but
provide the same shadow mask of about 0.26mm average. They get between
150 and 250 more resolvable pixels per horizontal line. And, you pay
for it...double the price of the 19" CRT, even though only about 35% more
glass is used.

I have the xterms running vi. I'm writing and debuggin code in them.

Fortunately, you are not me.

CRTs are much better at having a reasonable result with different
resolutions than LCDs, but you know that.

That's about right, unless you weigh the glass:-)
