Pros and cons
Pros
- At 1.7 pounds, the listed weight supports carrying it with a laptop for a portable second-screen setup.
- The included smart cover is also described as a stand, so a separate stand is not required for the cover’s stated setup.
- The listing describes both USB-C and mini-HDMI video connections, giving compatible devices more than one stated connection route.
Cons
- It has no built-in battery, so it needs an external power source during use.
- It is not a wireless or touchscreen display, so it does not suit buyers who specifically need those features.

What to know before buying
Listing details to confirm
The listing is inconsistent about panel technology (LCD in the details, IPS in a quoted specification), thickness (0.35 inches in dimensions versus 0.3 inch in feature text), and connection descriptions (including USB-C, mini-HDMI, Thunderbolt and 3.5 mm audio, with differing port counts and labels); confirm the selected listing’s exact revision and ports. USB-C video also requires a compatible video-output port and cable, while HDMI requires separate USB-C power; the monitor has no built-in battery.
