You can set up additional displays with your Mac in several ways. You can make all of your displays mirror each other, or extend your workspace with different apps and windows on each display. If you use an external display with your Mac notebook, you can also use closed-display mode.
HDMI technology is designed to be backwards-compatible—you can use a Category 2 cable on a Category 1 connection without concern. Going the other way is when you might run into problems. If you’re repurposing an old HDMI cable with newer equipment, it. This means if you connect an HDMI source component to a DVI equipped TV, you have to make a separate connection to access audio. Depending on the TV, this may be done either via RCA or 3.5mm audio connection. Ordinarily, there should not be a problem converting HDMI to DVI, but there can be. For example, 3D and 4K signals are not compatible.
Check your requirements
In case your Mac pro computer uses the Mini Display port, you are sure to have the possibility of working with the HDMI adapter. This will enable you to connect to your other device with the HDMI and achieve the desired connection.
- Check the ports on your Mac and see if you need an adapter.
- Check how many displays your Mac supports: Choose Apple () menu > About This Mac > Support, then click Specifications. On the web page that appears, the number of displays your Mac supports appears under Video Support.
Use extended desktop mode
Maximize your workspace with extended desktop mode, which lets you enjoy full-screen apps and windows on each monitor. Then, use Mission Control to organize apps and windows across your displays. If your Dock is on the bottom of your screen, it appears on any of your displays when you move your pointer to the bottom edge of your display.
Turn on extended desktop mode
