Using two monitors on raspberry pi can be pretty easy. The first thing you need is two monitors(If you are looking for a monitor click here) and a second Mini HDMI to normal cable. You can buy one The official one on cybertron marketplace here for $7.50 . There are a bunch of cheaper ones that you can find. You could always just get a adapter if you already have a hdmi cable. You can also buy one on Amazon for $6.99.

Once you have two monitors plugged in, you can select which one you want to be where. Just open the applications menu and go to preferences, then screen configuration. Then you can select where you want each monitor to be and which one is going to be the main. Only the Raspberry pi 4 model b or the Raspberry pi 400 have the double monitor features. If you have any other models then double monitors is not possible for you.

There are a bunch of apps and stuff that you can use to have a second monitor without double hdmi cables. I don’t really know much about that so you’ll have to look into it. That’s all on using two monitors on Raspberry Pi!
