Synnov 15.6-inch 1080P triple monitor laptop screen extender
Same idea as the 16-inch one: two screens that attach to the laptop. This one is a little lighter and a little cheaper.
If you only want one, get whichever is on sale. They both do the job.

I made a video about this one. Amazon shows it on the product page, so the link below opens it there.
