Ack. I didn't drill into their site far enough. I looked at their 
description for their "HD" sets, and it claimed 720 to 1080; I guess 
1024 is within that range, and I took what they said the wrong way 
(probably Gateway's intention). Even their HDTVs are castrated...

While you're right on the Gateway set, I'm afraid you're wrong on this 
one. Apple's 23" Cinema HD display has a native resolution of 1920 x 
1200. The 20" (non-HD) display is 1680 x 1050.

Yes, ick.

Gateway does. They've done it before, too...
