I have a HP OMEN laptop with dual graphics cards inside (Intel HD 630 and NVIDIA GeForce GTX 1050 Ti, drivers up-to-date). My laptop suffers from a wired mouse-lagging problem when the windows 10 UAC prompts out, and the problem can be solved by disabling the NVIDIA graphics card from windows device manager. However this solution comes with a cost: my HDMI port can no longer output signals.
Currently I don`t use my NVIDIA graphics card very much, and I really wish to switch it off to make the UAC prompt smoother. However I do need to connect my laptop to a second screen, and is it possible to switch the HDMI signal source to the Intel graphics card?
