Switching back to HDMI output

[JDoe12]

How would i go about switching back to HDMI? At the moment, when i install the drivers, i am stuck on using the display and the hdmi wont display anything even with the 3.5 touchscreen disconnected. I am pretty new to coding and the raspberry pi so excuse me if its a simple fix. I am using noobs on the raspberry pi 3B with a 3.5 inch RPI display touchscreen.
