Our take on the Blackview 14" Triple Portable Monitor Laptop Screen Extender

The Blackview 14" Triple Portable Monitor is a laptop screen extender that adds two 14-inch 1080p IPS displays, one on each side of your laptop, so you get three screens while traveling or working from a desk. It connects over USB-C or HDMI and weighs 2.2 lb. At $229.99 at Walmart as of November 5, 2026, it sits at the top of its recent range, with three stores pricing it new.

Questions and answers

Will it work with my laptop?
It needs a USB-C port that carries video, or an HDMI output plus USB power. Check your laptop's USB-C spec before buying; charging-only ports will not drive the screens.
Is $229.99 a good price?
It is the best new price across the three stores that list it as of November 5, 2026, but it is at the top of its recent range. Waiting for a dip below $230 is reasonable if you are not in a hurry.
Can I use just one extra screen?
The set is built as a dual-screen extender, so both panels are part of the same frame. You can leave one folded, but the product is designed for both.
Is it good for gaming?
No. The 60 Hz refresh rate and 240 ms response time suit documents, code and browsing, not fast-paced games.
How bright is it?
300 cd/m², which is dimmer than most laptops. It works indoors but washes out in direct sunlight.
What is in the box?
Expect the monitor, USB-C and HDMI cables, and a carry case. Confirm the cable set with the store, since bundles vary.
