I have an HP laptop with 2 video cards. An Intel UHD 620 and a Radeon R7 M340. Naturally I want the AMD card to be the default card, but I'm not sure if that's the case. How do this work and how can I tell what card is being used? Is it possible to disable the intel card?
U can go into the device manager and disable the intel card or go into the bios setting and disable it at he HW level if it allows you to but how dual video cards work it switches between cards intel for regular use and radeon when high end performance is needed like gaming or running high end apps like CAD one thing is battery life will be shorter just running the radeon card.
one problem form experience with dual video cards is when you disable one to run a single card it never runs correctly you start experiencing freezing or black screens on boot up....their a bit tricky their design to run together for best performance.
This exactly what happened when I disabled the intel card. Black screen after reboot. Thanks for explaining this to me. I was wondering why dual graphics were needed.
