Accsoon M1 turns your Android smartphone into an HDMI monitor

If you are a filmmaker or vlogger who likes to travel light, then an external monitor is often seen as a luxury. However, Accsoon may now have the solution to that issue. The company has launched the M1 HDMI to UVC device, which allows you to use your Android smartphone as an HD monitor. Note that it isn’t currently available for iOS devices.

The Accsoon M1 weighs only 4.8 ounces and measures 1.97 by 1.54 by 3.23 inches. It also has a standard ¼ 20 mounting hole so that you can attach it to your camera. The launch photos from Accsoon show the M1 mounted on a swivel bracket. However, that isn’t listed in the product specification so you will need to add your own ball head or monitor mount. There’s also a cold shoe mount on top of the M1 if you want to attach a microphone, light or other accessory.

The front of the M1 has an adjustable bracket to hold your smartphone. This will hold any phone between 2.5 and 3.5 inches wide. On the back of the M1, there is a Sony NP-F battery plate. As well as powering the device, the battery can charge your phone and your camera with the right cables. A battery safety latch ensures the battery won’t fall out in use.

Accsoon SEE app

The M1 has a full-size HDMI port to connect to your camera’s output and you link your smartphone with the included USB-C to USB-C cable. You then use the Accsoon SEE app to turn your smartphone’s display into an HD monitor. The app also includes a full suite of tools such as waveform, magnification, false color, histogram, focus assist, zebras, audio meters and more. You can access all of the controls using the smartphone’s touch screen. The Accsoon SEE app supports Android 8.0 and above.


With the M1, you can livestream the output from your camera using RTMP. This allows you to stream to popular video platforms including YouTube, Facebook, Instagram and Twitch via the phone’s internet connection. You can also record the output in HD on your device as a proxy file or for easy sharing.

Pricing and availability

The Accsoon M1 retails at $99 and will be available from authorized Accsoon distributors and dealers.
