The big, bulky outer box

Mars Pro" appears in a rather large box.

The distinctive design of the outer box
Saiga NAK

The box is very distinctive, so let's find out how to open it first.



Saiga NAK

Pulling it all the way out the top...



Saiga NAK

Open! The cushioning material is also very tight so as not to damage the main unit.

Hello Mars Pro
Hello Mars Pro
Saiga NAK

Here is the main unit of "Mars Pro"! It is smaller than the box, but still measures 24.5 cm (W) x 20.8 cm (D) x 17.3 cm (H). It weighs 4.53 kg, about the same as the regular PS5.

In addition to the "Mars Pro" itself...

  • Power plug 180W (18V/10A)
  • Power cord
  • Bluetooth remote control
  • User's manual
  • Fiber cloth
  • Washer

... was included in the package.

  • USB 2.0 x 2
  • HDMI eARC x 1

Let's get started! Plug in the cord and click the power button on the top of the main unit! By the way, it is touch-sensitive.

映ったSaiga NAK

It glows! It works! The fluorescent light is on in a sunny conference room, but the image is quite clear. I would like you to see it with your naked eye....

Please be careful not to look directly at the light source when using this product.

Saiga NAK

The bottom of the unit has screw holes for the stand and four extendable legs. In this photo, the unit is adjusted upward by slightly extending the two front legs.

Installed at an angle
Saiga NAK

Projectors are usually projected on a wide wall or screen, but you may have trouble finding a place to install the main unit, especially at home. Mars Pro" can be used in such situations where the projector cannot be placed in front of the screen!

It supports plus/minus 40 degree trapezoidal correction...

Oblique projection

This is...



Saiga NAK

...like this!

Of course I'm shooting from the same location. If the unit is slightly skewed, it will be corrected in a matter of 5 to 10 seconds and you can watch it with beautiful balance!

Image quality settings
Saiga NAK

From here, I'm going to dim the lights in the conference room and try a few things.

Select "Photos" from the settings and set the picture quality. There is some suspicious Japanese here and there, but I think the motion compensation is the frame rate. I will guess.



Settings Saiga NAK

In picture mode, you can set the picture quality from several presets. If you select "Customize"...

  • Brightness
  • contrast
  • Saturation
  • Sharpness
  • hue

Hue, etc. can be freely set.

The beauty of the image is obvious when a demo video is played. The high resolution allows for detailed rendering even on a large screen.

Since this is an e-sports media, we connected a Nintendo Switch. The "Mars Pro" has dual 10W speakers with sound coming from the device itself when connected via HDMI. Dolby Audio and DTS-HD Master Audio are also supported.

Game Mode On
Saiga NAK

Don't forget to activate Game Mode in the settings when playing games! Low latency of 20ms allows for stress-free play!

I actually compared Game Mode on and off and it makes a difference that anyone can feel.

Now that we have tried it out, the real value of "Mars Pro" starts here. Let's see how it works with projection screen sizes from 40 to 200 inches!

About 90 inches
Saiga NAK

The tallest member of the editorial team, standing at 185 cm, is lined up in front of us. His hobby is soccer.

This is about 90 inches. The distance between the "Mars Pro" and the wall is about 2.5m.

about 160 inches
Saiga NAK

And this is about 160 inches! The distance between "Mars Pro" and the wall is about 4.2m.

Unfortunately, we could not project the maximum size of 200 inches due to the lack of wall space, but the picture quality did not deteriorate even when the screen was enlarged!

The slow ratio of the "Mars Pro" is 1.27:1, so the relationship between projection distance and screen size is...

  • 80 inches at about 2.2m
  • 100" at approx. 2.8m
  • 150 inches at approx. 4.2m
  • 200 inches at approx. 5.2m

and so on.

Turn on auto avoidance from settings trapezoid correction
Saiga NAK

However, you have to be creative about where you place the unit, especially if you are using it in your home. This may require you to change the layout of your furniture, and in some cases, you may have to move the unit every time you use it. Mars Pro" covers such labor! It is equipped with "Intelligent Screen Fit" and "Intelligent Obstacle Avoidance" functions that automatically recognize objects in the projection screen and adjust the screen size!

Saiga NAK

As it is, chairs and people are in the way...

screen avoided!
Saiga NAK

Smart! It projects at maximum size while avoiding obstacles.

If you are using it at home, it may be difficult to secure the projection distance, so you may find the best setting by projecting from the maximum distance for now and then reducing the screen size. Of course, you can also set it manually!

Real Blink and You'll Be Killed

Dangbei's "Mars Pro" can be purchased from Amazon.co.jp and other e-commerce sites! It is a bit pricey, but the high reviews confirm its good performance.
