does this update fix the lcd monitor resolution problems? (wide screen particularly)

hmmm can you run 1080p on a 24" lcd monitor? I believe it is still no 1080p yet no? I'm planning to get a 20" lcd monitor...have some concerns about image stretching and black bars....wei come online ler...wanna ask some quick questions

now that I disposed of my psp, it is time to upgrade my monitor and get a console. My only concern is the damn monitor problem. Here are some of my concerns and i hope you guys can clear it up for me..(already did a search online)

Q: If I get a 24 incher, 1920 X 1200, can I do 1:1 pixel so that the monitor doesnt stretch out the vertical axis to 1200? Does that depends on the monitor?

Q: If I get 20 incher, the closest res that I can set on the xbox is 13xx X 768 ....If I set it at that resolution, does the monitor auto fill up the screen? is there still a problem with overstretch screen with the new dashboard? If I set the monitor to 1:1 (assume can be done on the monitor) I suppose the viewing size will be small and there will be black areas surrounding the image?

If I can do 1080p on a 24 incher...I might just get that instead...althought 2 X more expensive than a 20" What I am afraid is M$ decides to update the dashboard again and support 1680:945 after i bought the 24"

that answered the dell question thanks.
there are still some other questions that I'd need an anwser.

btw, is it possible to get the 1:1 option if you feed the monitor 1080p over a hdtv source? or is it just a problem with the xbox?

after some extra reading..seems like there isnt any 24" lcd out that that can do 1:1 with the 360 that I know of. This is really unfortunate

My PC is a htpc and is under the tv, I have a 25ft vga cable running around the room and my monitor is placed 2 ft beside me and my bed. I really wanna get a big screen lcd for now. 42" 1080p lcdtv is pretty expensive now....was hoping that a 20-24" monitor would last me till May 2007, by which I would get a 42"
