Title says all I'm not very good with computers but I watched a pretty basic YouTube video and it said plug hdmi's in then go to display settings on my PC. My orientation i have set to Landscape and under multiple displays I selected Extend these displays. For some reason it won't let my mouse go to the other screen and I can't drag anything over.

[Press the Button]

In the section where you can see your 2 displays plugged in, do you have them in the correct order?
As in if you want your primary to be your right monitor, you drag it to the right side of the 2 displays and select the box making it your main display.
If it's backwards you would have to move your mouse to the other side of the screen to drag things.

Make sure you click Identify because when I was setting up my monitors, the one on the right physically was configured to be on the left of my main screen.
