Projector with lens cover folded down.
Viewsonic

Do you want a big screen TV, but do not have the space or budget for one? Viewsonics M1 Mini is a small pico projector that literally fits in your pocket and can project a large image into a dark room. It lacks some of the features of its big brother – M1 + – but at $ 150 it is also less than half the price.

Here’s what we like

  • Tiny – fits in your pocket
  • Comes with three different color peaks
  • Good sound
  • Affordable

And what we do not do

  • The resolution is only 854 x 480
  • Needs to be used in a dark room
  • No wall charger / power supply included
  • No tripod mount
  • The battery is good for 2.5 hours

Wait! Is it a projector in your pocket?

Pico projectors – small portable video projectors – were popular about a decade ago. Then they kind of disappeared for a while and are now experiencing a renaissance. Viewsonic M1 Mini, the little brother of the M1 + that we reviewed a short while ago, is the latest addition to the Viewsonic video projector family.

In some ways, the M1 Mini is similar to the larger and lighter M1 +, but it’s not just a shrunken version of the more expensive pico projector. For less money, you get fewer features and less flexibility. But for many, it will not be a business breaker.

When Viewsonic christened the projector, it hit the nail on the head. The M1 Mini is truly a very compact device, measuring only four inches and one inch high. The top of the projector has a pop-up color panel that allows you to replace the teal panel that the projector has out-of-the-box with a gray or yellow that is included in the box. I do not really know why they did it, it seems like putting lipstick on a pig (sorry to Miss Piggy). Other thanks look nice, they seem pointless, because they do nothing more than change the color of the top of the projector.

Inside the case is a 50-lumen LED light source, a battery that is good for a maximum of 2.5 hours of playing time and a really nice 2 W JBL speaker. You will not blow up the neighbors if you hold an outdoor movie night, but in an interior room it sounds good.

A fold-down lens cover also doubles as a tripod for the projector, and as with the big brother, it can be lifted upwards to provide a practical carrying handle. Unfortunately, the underside of the projector lacks the tripod mount that the M1 + offers, a feature that is really lacking. Using a tripod, you can easily place the projector at a 90-degree angle to the projection surface. With the M1 Mini, you need to figure out a way to raise the projector so that the image is not displayed at floor level or is unreasonably distorted. The vertical keystone function is fine, but it still does not compensate for an image that is too distorted due to the angle between the projector and the image surface.

Here a port, where a port

With the M1 Mini so compact, there is not much room for sockets or controls. The front of the projector contains only the lens – the manual focus wheel is accessible from the right side of the projector (seen from the front). You need to focus the image depending on how far the M1 Mini is from the surface you are projecting on. The projector has automatic vertical keystone correction, which is nice because there will be times when you will not be able to place the projector exactly perpendicular to the surface.

The right side contains micro USB and USB-A ports.

The rear panel includes a small slider to turn the projector on and off. Unlike the M1 +, the power does not control moving the stand up or down, so you must be careful to remember to turn off the projector when you have finished looking, otherwise the stand may block the unit’s cooling valve.

The doors are divided between the left and right side panel. View from the front, the right side panel contains two doors. Both are USB ports, one of which is a micro-USB and the other a USB type A. You can input video from either or from the HDMI port on the left panel. The micro USB port also acts as a power-in port, and Viewsonic provides a USB-to-micro cable. However, it does not provide a power supply to wall warts. You must provide this on your own. You can input video from the Type A USB port while charging the projector with the micro-USB port, but using the USB port for video means you better have a charged battery as it cannot be used for both charging and video input. at the same time.

The left side has an HDMI input.

For my testing, I used video from a number of sources including a flash drive, an Amazon Fire TV Stick, a USB DVD player and a laptop, with no problem playing videos from any of these sources. Another test involved me connecting the M1 Mini to an HDMI video output and projecting the laptop screen. Again, no problems other than the brightness of the image.

As with other pico projectors that I have tested, I projected the image from about 8 meters from a large piece of white foam plate and also tested to project against a wall-painted light blue. The difference in the brightness of the image was immediately noticeable, with the image projected on the wall noticeably darker but still acceptable in a completely dark room. At eight feet, the picture was about the size you would get on a 32-inch TV.

Not too bright

The M1 Mini can actually project an image as large as 100 inches. However, keep in mind that the larger the image you project, the less light the image will be. You can blame physics’ inverse square law for that. It also contributes to the lack of brightness is the luminous flux. Viewsonic values ​​this at 120 lumens, but in ANSI measurements the output is barely 50 lumens. It’s just not very bright, and if you project against a dark surface, the image is almost unrecognizable.

It addresses two other points to consider. The first is mentioned above – even a moderate amount of light in the room will wash the image completely out. The second problem is the surface you are projecting on. While white, like a white wall or a sheet, is preferable for the best image, I got an acceptable image that projected on a light blue wall without a noticeable distortion of the colors in the projected material. The limited optical resolution of only 854 × 480 also reduces the sharpness and clarity of the image on higher resolution source material.

Not really perfect

Viewsonic

I like the M1 Mini, but there are a number of places where it falls under the M1 +. The most noticeable of these is the brightness of the image and the resolution.

I’m also not very happy with the short 2.5-hour battery life, especially with many movies approaching or exceeding that length. If you are considering projecting Avengers: Endgame, it’s better to have a battery pack or an electrical outlet on hand, which loses the whole point of having a projector with so much portability. Even with a nearby wall outlet, you need a nipple because Viewsonic has no power supply with the projector.

The source of your video material is also a problem, especially if you are watching outside. If you do not want to run an AC extension cord for a laptop or Fire TV Stick / Roku, you will probably be limited to video on a flash drive or a battery-powered device, such as a phone or tablet with an adapter, between the device and the projector.

Finally, I really miss the tripod mount that the larger and more powerful M1 + has. The M1 Mini’s fold-down lens cover / stand does not give you nearly the flexibility to mount the M1Mini at a height of 90 degrees to the surface on which you project the image. This is somewhat offset by the projector’s automatic vertical keystone correction, but there is just as much the correction can do to correct a large horizontal angular deviation between the projector and the viewing surface.

All this does not mean that the M1 Mini is not worth considering. But think hard about what, where and how it would be used. It’s a cute and not too expensive projector, but for many it makes more sense to spend more money and get more flexibility and usability.
