Is the Onn 15.6-inch portable monitor worth it?

At $43 at eBay as of November 5, 2026, it is a cheap way to add a second 1080p screen. It suits documents, browsing and video, not color-critical or gaming work.

Does it work with a MacBook or a phone?

Yes, over USB-C if the device supports video output, or over mini-HDMI with an adapter. Check that your USB-C port carries DisplayPort video, since some phones and laptops only charge over USB-C.

How bright is the screen?

It peaks at 280 nits, which is dim compared with most laptops. It works best indoors away from direct sun or bright windows.

Is it good for gaming?

No. The 60 Hz refresh rate and 20 ms response time suit office work and video, not fast games.

Can I mount it on a monitor arm?

No. It is not VESA compatible, so you rely on the built-in triple-angle stand.

What comes in the box?

Expect the monitor and its stand; check the listing for which cables are included, since mini-HDMI cables are less common than full-size ones.

Our take on the Onn 15.6 inch FHD LCD Portable Monitor

The Onn 15.6-inch FHD Portable Monitor is a 1080p IPS panel in a 2.43 lb silver frame with a built-in triple-angle stand. It connects over mini-HDMI or USB-C and includes a built-in speaker, an anti-glare finish and 170-degree viewing angles. At $43 at eBay as of November 5, 2026, it is a very low entry price for a 15.6-inch 1080p portable display. The trade-offs are modest: 280 nits brightness, 60 Hz and a 20 ms response time.
