If you look closely at the screen, you can see the individual pixels, 
and the space between them. The space between them is not illuminated so 
there is a thin black border surrounding every pixel. Now that is 
extremely thin, but the effect is that of a "screen door".

In general, the lower the dot pitch, the less you are going to see the 
screen door effect. The Viewsonic I ditched after 4 days has a pitch of 
.264mm. The SGI I was trying to replace it with had a dot pitch of 
.230mm. The difference for a perfectionist like myself is HUGE. Greys 
and other shaded areas come up as "stippled" with the Viewsonic.

I am very disappointed with current LCD offerings. There is no 19" flat 
panel with 1600x1200. The only true high density flat panel on the 
market right now is the $6-$10k IBM T221, Viewsonic 2290B, and two 
others using the same internal LCD panel.
