Q: Does this portable monitor have built-in speakers?

A: No, the SideTrak portable monitor does not have built-in speakers.

Q: Does this equipment require driver installation? i need something that is plug and play.

A: I know I find it super confidence inspiring when nobody will answer questions I ask!!! Not the retailer, not the manufacturer, no other buyers/ owners. It’s not like Nick asked for anything unusual. He just wanted to know whether or not it is plug n’ play! This is something I need to know too because with work computers you can’t just go loading and configuring things however you want. Lately they’re practically handicapped, good only for what you’re supposed to be doing on them, according to someone else’s opinion. And even then they are struggling. The last thing anyone wants is to spend several hundreds of dollars to discover they have something they can’t use. So is it too much to ask, to get an answer to a simple question?

    Good 2nd monitor

    Bought for school. The magnet holds up well. I use it as a stand alone more than attaching to my laptop as sometimes it’s a bit heavy

    Convenient but the 2 wires are a hassle

    It’s very convenient when traveling. The screen itself is not so bulky but I wish it didn’t require 2 wires to be connected to the laptop in order for it to work. My old external monitor from another company only required one wire but it was not the kind that could be attached to the laptop screen like this one.
