I got this tip from my son’s friend, who is staying with us at the farm for a week (after a negative COVID test.)
Izzy pulled his laptop for schoolwork out of his bookbag and then pulled out this 15.6 inch portable LED monitor to serve as a second screen.
The monitor – about the size of a Macbook – fits into a convenient carrying sleeve.
At home I’ve got two 27-inch monitors, but I’ll admit – I was not aware that “portable monitor” is even a product category.
I immediately bought one for myself to use as a second monitor when traveling. ($99 on Amazon.)
