I need to replace my LCD monitor and have done some research on a replacement. I was all set to go the 22" Samsung 226BW for about $300 from Compusa. However, I have heard a lot of positive things about having dual monitors (yes, my video card has two dvi outputs). I do home video editing and general computer stuff... Looking at going two 19" monitors for around 200 each, so about 100 more for the dual set up... Is there a real benefit? Thanks!
