Y40B 2.01-inch Wired Magnetic Selfie Monitor

The Y40B is a compact 2.01-inch wired magnetic selfie monitor for buyers building smartphone filming, live-streaming and creator-accessory assortments. It provides a rear-camera framing screen while remaining physically connected to the phone. That wired, battery-free architecture separates it from the X40Y wireless 2.0-inch monitor and from larger touchscreen monitor formats already listed on the site.

Wired and battery-free product position

The Alibaba source identifies a 2.01-inch IPS full-viewing-angle display, USB-C wired connection, magnetic mounting and a design without a battery. It should not be marketed as a wireless monitor or as a rechargeable standalone display. Phone support depends on the current cable, connector orientation, operating system, video or mirroring path and application workflow.

Sample validation for distributors

• Confirm screen size, viewing angle, color, brightness and latency on the current sample.
• Test connection, power behavior and mirroring with each target phone and operating-system version.
• Verify whether any adapter, application, permission or setup step is required.
• Check magnetic plate placement, rotation, holding strength and clearance around the camera.
• Test cable flex, connector retention and repeated attachment during vertical and horizontal filming.
• Approve housing finish, accessory set, instructions and packaging before artwork.

For wholesale and private-label programs, provide the intended phone list and filming workflow with the RFQ. Compatibility and any document claims should be matched to the exact Y40B sample and production lot.
