I went to the Samsung Website, and was immediately assaulted by a "We'd like your feedback" popup.
However, none of the links listed had anything to do with EX2220 (at least nothing obvious). I clicked through the first few pages of links, and still came up empty handed.
Then I tried the dropdown list controls in the "Select your model" box. The first selection was easy -- I have a Monitor.
But then I was stymied with the choices for Product Subtype -- Essential, Business, Premium, Professional, Specialty -- none of these made much sense for my monitor. I bought it at Costco for home (and work-from-home) use. I looked over the entire Monitor, front, back, underneath -- nowhere were any of these terms used. I went to the garage and looked all over the box. Still, nothing.
So, I did the hardest possible thing which was to, one-by-one, check each and every one of the lists. No matter which Product Subtype I chose, none of the Product Model lists showed my model number. Finally I noticed that when I chose "Essential", the Product Model list showed an entry for "21.5" Widescreen LCD Monitor".
I then clicked "Find Download". At which point I got to this screen:
...with no results.
I then looked through the contents of the CD and was able to find the appropriate driver. So much for the convenience of the web!
