Thanks for the reply!  I suppose I'll learn more than I want to over the next 
few months as I try to get the Wavlink to work. ;-)  (Not sure if it will need 
any of Display Link, Display Port, or Alternate Video mode, or any other new 
to me technology, but I'm sure I'll find out. ;-))

Fortunately (well, the silver lining in the very dark cloud is that) there 
probably won't be very many meetings (if any) that I'll want to take the 
laptop to.

(As of 8pm tonight, my area is in a mandatory stay at home order (except for 
health or safety reasons or essential jobs).  Should be interesting.)

Stay healthy!
