[NAME] I would connect your Dell U2719D monitor to the HDMI port using the included HDMI cable that is supplied with that monitor. In addition, I would change the connection of the Dell S2209W monitor from the VGA port to the DVI port using the DVI cable that is supplied with that monitor. Both the HDMI and DVI ports provide digital video signals and deliver the highest quality video signals. Here are the User Guides for both monitors: [URL] [URL]  
Hi forum I hope all are safe and doing well. I really could use a little help getting my Dell XPS 8700 set up with an additional monitor. I already have a Dell S2209W monitor connected to a NVDIA GeForce GT635 graphics card VGA port. Here's what I need to know. The 2nd monitor I want to connect is a Dell U2719D I need to know out of the 2 ports I have available where should I connect  my Secondary monitor to the HDMI [middle] or DVI [extreme right] ports? [IMAGE]    My 2nd monitor has the following connector ports, HDMI connector, and DP connector (in) . What is the best configuration for connecting my 2nd monitor. I am running Windows 10-64 bit OS if that helps. Can you help? Thanks  Tony
