You can connect speakers via the 3.5mm jack on the screen. You can find compatible speakers by filtering "audio connection" jack 3.5mm in the speakers section.

You can connect any speaker with a 3.5mm jack plug. You can also use speakers that have a 3.5mm jack plug + a USB A cable, but you have to plug the USB A cable into the tower or labtop so that you have enough power for the speakers, if you plug both into the screen, the speakers will remain mute.
