Thanks for your thoughts. Trying it another machine, I think, is a waste of time. If it won't run properly on the unit I bought it for, it's really not worth fooling with. A different connector was a possibility but the video card has 2 DVI ports and a mini-HDMI. The monitor has a standard HDMI which would mean ordering an adapter or ordering a hybrid cable and waiting 4 or 5 days. I'm going to call the unit defective and do the Amazon RMA thing this morning. Last time around Amazon cross shipped a new unit which would entail maybe 3 days wait. Sounds like the best solution. If the new one behaves the same way, I'm going call it an under-powered video card and think about a new one of those. We'll see in a few days, I hope.
EDit: 5 minutes after I processed the RMA, an email from Amazon arrived confirming they have ordered a replacement with guaranteed 2 day delivery!
Gotta love it.
