They're all extended. Doc -----Original Message----- From: Cindy Sievers [mailto:siev...@lanl.gov] Sent: Thursday, August 02, 2007 2:54 PM To: Nguyen, Doc Lap; Brian Corrie Cc: Douglas Kosovic; ag-t...@mcs.anl.gov Subject: RE: [AG-TECH] AG on >10 displays
Doc, Are you able to move video between the two screens? Or do the 2 very wide screens act independently of each other? I'm wondering if they behave as an extended desktop or if they are completely separate of one another..... Thanks for the info!
