I hope everyone is having an enjoyable summer

Quick question about camera mounted monitors.

Who uses what, what sort of arm do you mount it to, size, weight, resolution.

I shoot on an Panny HPX 3100G. it does have the little flip out monitor, but its not meeting my needs.
I do have access to an Ikegami 9 inch monitor, but have no way to mount it to the camera, and it runs off a brick.

As always, thanks in advance.

Best.
