With the rise in portable projectors, an average consumer can take advantage of a projector without the complex setup and pay a lot of money.

However, not all portable projectors are made equal. Most of them lack crucial features like high brightness, multiple connectivity, and a smaller projection.

This is where the Miroir M631 comes into the picture. It is a portable projector that weighs less than 2 pounds. Still, it offers excellent features that you’d expect from a full-size or regular projector.

As a testament to this projector’s quality, it is sold in Apple stores and natively compatible with Apple products like iPhone, iPad, MacBook, Mac Mini, and more.

In this Miroir M631 review, we’ll go over the projector’s design, build quality, and performance. Later, we’ll let you know if you should go with this projector or are better options available.

Miroir M631 Review

First Impression & Design

Previously we’ve featured Miroir’s other portable projectors like the Miroir M220 and Miroir M289, and both of them are solidly built. The same is the case with the Miroir M631. It is wider than both projectors and offers significantly better performance.


At first look, the Miroir M631 looks substantially bigger than the M220 and M289. It’s because this projector is 9.5 inches wide, 5.4 inches deep, and 1.5 inches high. On top of that, it weighs just under 2 pounds, making it easy to carry anywhere with you.

In terms of design, the Miroir M631 has a very functional design; it isn’t fancy but gets the work done. The front features the projection lens and sliding cover to protect the lens when you aren’t using it. Next to the sliding cover, there’s are built-in 3W dual stereo speakers that handle the audio department.

The top is clean and features only the Miroir logo. Control buttons are placed on the projector’s right side, including volume up and down and source selection. In comparison, the projector’s bottom contains 4 rubber feet and quarter-inch threading to either ceiling-mount it or mount it on a tripod.

The projector’s back contains several connectivity options. It includes:

  • 2x HDMI ports
  • 1x USB Type-A port
  • 1x USB Type-C port
  • 5mm headphone jack
  • Reset button

Unfortunately, this projector doesn’t have any wireless options, which can be a big bummer for most. Even our sub-$200 Artlii Energon 2 projector comes with wireless connectivity options.

Build Quality & Performance

In terms of build quality, the Miroir M631 has a complete plastic build. The projector internals is wrapped in a plastic casing, which is sturdy and suitable for day-to-day usage.

However, make sure that this projector contains several lenses and mirrors to produce a projection. Hence, a slight drop from waist height might be enough to damage this projector permanently.


With the box, Miroir doesn’t provide any carrying or protective case. Hence, when not in use, you need to store this projector carefully and make sure there isn’t additional weight put on this projector.

Moving onto the performance, the Miroir M631 is a battery-powered projector. However, due to advanced features and high brightness, the Miroir M631 doesn’t last long in battery mode. With Eco-mode, it can only last up to 2 hours on a full charge. Hence, I’d recommend using this projector with its power adapter whenever possible.

Specifications-wise, the Miroir M631 comes with 1920 x 1080p native resolution and supports up to 4K resolution. It can display 4K content by downsizing it to 1080p, making it ideal for watching movies and TV shows.

Being a long-throw projector, this projector can produce up to 120-inches from a 10-feet distance. You can quickly achieve a 120-inch screen from a light-controlled room. But the projection starts to fade when you introduce ambient light or use the projector during daylight.


For daytime usage, you can comfortably use this projector with a 50-60 inches screen, whereas during nighttime, you can stretch the screen size from 100-120 inches. In a dark room, the colors look vibrant, and the contrast and color saturation looks apt.

Miroir rates that the M631 can produce up to 700 lumens brightness; however, I found the light source slightly dimmer even in the brightest mode. To make the best use of this projector, I’d suggest using it in a moderately dim room.

In terms of display projection, the Miroir M631 is backed by a DLP projection technology and an LED light source. Being a DLP projection, I couldn’t notice the rainbowing effect, which is a good thing. It has a contrast ratio of 1000:1 and 8-bit color depth processing, which supports up to 16.9 million colors.

For added features, you get no-fuss options like automatic focusing and keystone correction. As a result, you can point this projector at any wall and any angle. The projector will automatically adjust the projection to produce a rectangular projection.

The built-in features also work well and offer good audio output. However, the bass performance is relatively weak and very common with built-in speakers. Hence, to get the best audio output, I’d recommend getting an external speaker system.

Important Features & Functions

  • Full HD native resolution: Higher native resolution ensures the projection output is sharp and crisp. As a result, you can comfortably watch YouTube and other streaming services on this projector. Moreover, it also supports 4K content, which makes it a worthwhile experience.
  • Seamless multimedia usage: Being portable, you can connect the Miroir M631 with several devices like smartphones, tablets, laptops, gaming consoles, and more. You can also connect it to Amazon Fire TV Stick or Roku Stick and turn it into a smart projector in an instance.
  • Higher Brightness: High brightness means you can use this projector even with ambient lighting. The brand claims a brightness output of 700 lumens, which is enough to use this projector during evening time and with little ambient lighting.

The Miroir M631 is targeted towards someone who wants a battery-powered projector without compromising on features like resolution, brightness, and picture quality.

It weighs less than 2 pounds; hence, you can comfortably carry this projector anywhere with you. However, there are several other competitors this projector goes against, which can be a better option for the price you pay.

As a result, you can look at devices like LG PF50KA or the Wemax Dice. They’re both portable projectors and available at a similar price range. The only downside is both the projectors aren’t battery-powered like the Miroir M631.
