30" monitor with my 20" imac

ive got a 20" iMac G5 400G HD 2G RAM + Westinghouse 17" widescreen LCD. i just cant stop looking at 30" monitors and getting rid of the 17". i was wondering if anyone else has done this already? and if anyone had a suggestion for wich one ta get? ive been looking at this http://www1.us.dell.com/content/products/productdetails.aspx/lcd_w3000?c=us&cs=19&l=en&s=dhs any help on this would be appreciated

guess im thee only one. now for a better Q. what is the max resolution that can be used with screen spanning on my imac (it is the newest model)? i think its 2048*1536 but im not sure. im also looking for any suggestions on which 30" monitor to get. please help. thanks

i don't think you can run 30" display with iMAC. you need a special GPU for that.
too many pixels fro iMac's graphics card

this post went no where so i posted this http://www.mac-forums.com/forums/showthread.php?t=21322 it didnt go antwhere either but it is more detailed on what i want to do. thanks for your help

I wouldn't want a 30in that only supported 1280x768, I would look into the Dell 24in that supports 1920x1200

this thread is dead please look at and post on my other thread if you have any info for me thanks thanks thanks
