Thanks, but no luck. There are no labels (it's a laptop screen), and the
Dell product page<http://accessories.us.dell.com/sna/productdetail.aspx?sku=R6313>doesn't
provide any useful information. Too bad MonitorWorld doesn't
allow indexing <http://monitorworld.com/robots.txt>, or it would actually be
searchable (their search sucks).
