So I have a DELL xps 8900, Win 10 with a GeoForce 720 card. When I try and view videos at Amazon they are not HD. If I looking device manager I see the generic Intel video and the Nvidia. I'm connected to the monitor via HDMI. How do I force the system to use the Nvidia card?
Hmm, checking on YouTube I can play videos at 1080p so how do I get the Amazon videos at HD?
Do you have two video cards?
