You're quite welcome.
Chances are your photos (or any photos for that matter) will look as smooth as they can on a 20" LCD (if other technologies are not considered) because of the small pixel pitch - smaller LCDs have it bigger, bigger LCDs too, usually.
When you'll be shopping for one, go to a big store where they showcase them just to see it. Look at the picture for a few minutes to get used to it a little. Then try a 20" IPS screen (which I highly doubt they'll showcase, but you might get lucky). You should see that the image displayed by it is kind of smoother and it doesn't matter much which angle are you looking at it from, the picture won't change nearly as much as it would if it were a TN panel (which most LCD monitors have these days, they're fairly cheap and their specs look good on paper... except for the ones you should be looking for, which often aren't shown).
That said, it might be difficult to see it in the shop, due to the lighting conditions and such. TN panels have also gotten bigger. Nevertheless, I have a few years old Eizo L557, which has a PVA based panel. When I print from my HP DeskJet 5740, the prints are very close to what I can see on the monitor - that's without any calibration at all.
These two sites list some LCD monitors and their panels:

Btw., if it's still available, NEC 2070NX should still be a good buy (watch out for letter plays!). By the way, most widescreen LCDs have TN matrices and poor backlighting, although you might not see it unless you have a dark photo - but then it can be too obvious. Few of those are really of good quality.
