There is more...
Buy.com has the Planar PL2010M, #997-3469... 20.1", 1600x1200, supposedly S-IPS panel, 250 brightness, 700:1 contrast, 16ms response... for $262 w/ free ship.
Buy.com also has the Planar PL2010M, #997-2827... 20.1", 1600x1200, supposedly S-IPS panel, 300 brightness, 1000:1 contrast, 8ms response... for $362 w/ free ship.
I called Planar tech support and ask about the differences.
1. He could not confirm panel type on either model.
2. He said the 3469 was an earlier model.
3. He also said "I have one of each on my desk and they look the same"...
Buyer reviews on the 3469 at Buy.com are high... (4.5/5 average on 9 reviews)
So, $262 might be a cheap price on a good monitor for other than games.
