2 * 15.6 inch screens next to each other on a raspberry pi 4 running dak board as “one screen”

Hi, I want to get a DAKboard, and I have a cupboard where two 15.6-inch screens could easily sit next to each other. I’ve read that you can configure them so that two screens appear as one large display, which means you only need one DAKboard setup to manage it. It seems like you need to configure the Raspberry Pi for that.

Do you think this is possible? Does anyone have experience with this setup?
