I have the samsung 2494HM 23.6" monitor,
the HM model has a fully adjustable stand, portrait mode, brilliant colours, nice and bright.
The problem is its 16:9, but nowadays its very hard to pick up a new model 16:10, the only 24" monitors for 16:10 that I've found are old.
The only bad qualities about this monitor is there is no RTC (Response Time Compensation), so you get a native 5ms picure. This means you do get ghosting if 2 contrasting colours are changing very quickly over eachother. Not terribly noticable but its there.
The plus to this monitor is its great panel quality (besides ghosting (barely noticable unless you're looking), fully adjustable stand (its quite spectacular), usb hub, DVI, VGA and HDMI connections also.
My friend has the T240, which is 16:10, brilliant quality except the stand is NOT adjustable and it has the samsung "plum" bezel which means its kind of round and ugly.
Just my 2 cent.
