ViewSonic M1+ portable smart Wi-Fi projector review


It is truly identical to its predecessor in terms of looks and weight. As for its palm-size, the ViewSonic M1+ will fit in your hands. It weighs 1.7 pounds and measures 5.7 x 4.96 x 1.57 inches.

Rotating handle

There’s a rotating handle that—when folded up—covers the lens, protecting it from damage (but not from dust). When folded down, the handle serves as a base for the projector and turns it on. If you move the handle 180 degrees to the rear, you can point the projector toward the ceiling if you and/or the kids don’t mind lying on your backs while you watch a movie.


The ViewSonic M1+ is basically the identical twin of the M1. Right out of the box, you will be given a manual, a soft felt sleeve (or case), a charging cable and adaptor, a USB type C cable, a remote control and 1 unit of the M1+ itself.


HDMI: 1, (HDMI 1.4/ HDCP 1.4)
USB Type C: 1 (5V/ 2A)
Audio-in (Bluetooth): 1 (BT4.2)
USB Type A: 1, (USB2.0 Reader)
SD Card: Micro SD (32GB, SDHC)
Wifi Input: 1 (5Gn)


Audio out (3.5mm): 1
Audio-out (Bluetooth): 1 (BT4.2)
Speaker: 3W Cube x2
USB Type A (Power): 1 , (USB2.0 – 5V/1A,, share with USB A Input)

Screen size

At a distance of 2 meters, the projection size is about that of an 85-inch monitor. With the swiveling stand, the M1+ can project at any angle within 360-degrees. This means it can even project upwards to the ceiling or downwards to the floor


Its native resolution is 854×480 pixels. Based on our usage experience, visuals start to become more noticeably pixelated when you stretch the distance between the wall and the M1+ beyond 2 meters.


Coupled with the automatic keystone detection and adjustment, it will automatically correct the projections to be proportionate no matter the projection angle. The auto keystone feature also seems to have improved from the predecessor considerably.  


You absolutely wouldn’t require an extra pair of speakers unless you’re going for something on the higher end. With a great volume range, some bass and crisp clarity, the audio at max can easily fill an entire living hall. Having said that, it definitely won’t match the quality of branded standalone speakers but as a built-in unit, it is more than suffice.


The M1+ has a battery life that can last up to 6 hours of continuous use in one full charge. That is equivalent to about 2-3 movies depending on their length, which is a no-brainer. Additionally, it also has the auto-blank feature that is inherited from its predecessor, which cuts power to the projection beam when objects are detected too close to the lens (less than 30cm away).


The projector’s few controls are located on the rear panel. They consist of Plus, Minus, and Back buttons to navigate the on-screen menus, and an On-Off button which doubles as an Enter button. The included remote has similar keys, but it includes controls to access the Settings menu and to adjust or mute the volume. 

Eye Care

Utilizing reflective light, which bounces off the wall or projector screen before hitting your eyes, the projector makes the viewing experience virtually blue light free, less invasive to your sight and reduces eyestrain over prolonged viewing periods.

ViewSonic M1+ screen mirroring

The ViewSonic M1+ can connect to WiFi on its own. By doing so, the M1+ can be accessed by smartphones for screen mirroring. In my case, I use an iPhone 11 Pro, and screen mirroring was pretty much a breeze. In mere seconds, the M1+ was able to mirror my phone’s screen and replicate video playbacks in full-screen format. For Android, the app to use is Chromecast.

I love this feature the most as I do binge-watch on Netflix and performing a screen mirroring with a projector makes the experience a cinematic one at home.
