First and foremost, there is a **Display Switch** near the battery connector that must be pushed "toward the
front of your system unit" if you have a CGA that is your only (or primary) display adapter, or "toward the
back of your system unit" if you're using an MDA as your only (or primary) display.

In PCjs, the 5170 **Display Switch** is configured with the <[ChipSet](/docs/pcjs/chipset/)> *monitor*
property, which you can set to either "mono" (aka "mda") or "color" (aka "cga"). Unlike the Model 5150/5160 DIP
switches, there is no UI for this switch, so once the machine has been created, it cannot be changed by the user.
