Hi wayuphigh, welcome to the FT Forums! I think there are a few Mavic users here, and I know the FliteTest team also use/love it, but you might find there are still not that many mavic users on this forum.
That said, I do believe that in order to view the video feed on pretty much most / if not all DJI products, using their video system, you will need a mobile device.
One way to avoid that is to get their goggles. They have a proprietary video link / protocol, so it really will be only their goggles that you can use to view the video. If you're new to the Mavic, it might just be a bit daunting to also invest in the goggles. I would fly line of sight and learn to use it before venturing to that, but that's just me.
Do you not have a mobile device you can use? Either a phone or tablet? I believe they support both android and ios, so you're not bound by a particular manufacturer. Heck, DJI might even sell a tablet themselves just for this purpose. I thought I saw someone with a DJI tablet flying a Phantom 3 back a few years.
