I'm unaware of any Apple connection here.
Try this. Call one of the Apple stores and ask them to do this for you.
Why is the 23" model considered HD and the 20" not HD? Wouldn't the 20"convert the HD signal to EDTV- (HD in a smaller size)?
What HD sources are available to play thru ( or in) a Mac with the 23" model?
Can HD from an HD Sat receiver be recorded in the Mac to play thru the 23"? Can any HD source be recorded(and what source)?
Can any HD source: receiver,TV tuner,DVD be connected directly to the LCD?
Isn't the pixel size similar and count proportional in # to each model? Again,why is the 23" = HD,and the 20",not?
If there are no HD sources, what's the hype about the HD spec, any way ! ...isn't is meaningless??
Can you pass this to Apple if you lack the answer?
