Unboxing

The projector comes in this black box. To be honest, I thought that projector is also black, but it is white. There are no specifications or features on the box.

When you open it, you will find the cardboard box with remote control, AV cable, HDMI cable, and Power cable.

There is also a manual, screwdriver, and wipe cloth to clean the dust card and inner of the lens.

Then we have 100 inches 16 to 9 projection screen. I didn’t order it additionally, so it probably comes with every projector. It is awesome.

I also like the user manual. There is all information about the projector, its specifications and how to use it.

Finally, we reached the projector itself. Let’s take a close look at it.

As I already said, the DR.J Professional AK-40 projector has a white body.

The weight is 2500 grams.

You probably won’t carry it with you to the office or college, or even from room to room. It is better to find a good place for a projector in the living room, install it on the ceiling or a special tripod.

On the front of the projector, we can see a lens and IR receiver. By the way, the lens is projected from dust by a plastic cap.

On the top, there are focus and keystone wheels, as well as a control panel with the power button, source, menu, return, up/down, left/right, and OK.

By the way, there is a warning do not to look into the lens. I think you should listen to it.

Before using a projector, you need connect the power cable and switch on the power. There is also a VGA port, the second IR receiver, two USB ports, a TF card slot, an AV, and a 3.5mm audio jack on the back of the projector.

I also want to show you the remote control. Actually, it has the same buttons as the control panel on the projector. However, of course, it is more comfortable to use remote control then go to the projector every time you want to change the video or turn the volume up or down.

User Interface & Settings

DR.J Professional AK-40 projector doesn’t have an Android operating system, so you need to connect an external device to it to play the video or game. Fortunately, there are many connectivity options. For example, you can use VGA or HDMI ports to connect a laptop, PC, or game console to the projector.

There is also Wi-Fi support, so you use Miracast or iOS cast for wireless connection with Android and iOS smartphones. By the way, you can also connect mobile devices to the projector using a USB cable.

You can also play video or presentation from a USB flash drive or TF memory card.

Sound and noise level

Before watching the video, let’s check the sound and noise volume.

DR.J Professional AK-40 REVIEW: This Full HD Projector Is Very Bright!

As you can see, the maximum sound volume is 78 dB. I also want to say that the sound is really good. It is not only loud but also has good bass. The sound plays an important role on the projector because it gives the feeling of a movie theater at home.

The noise volume of this projector is about 43 dB. Yes, you will hear the projector making noise in a quiet room, but that’s not a problem when you are watching a movie.

By the way, I forgot to tell you about the specifications of the DR.J Professional AK-40 projector. While you watch the video samples, I will tell you about the specs.

You know, the brightness of a projector is so high that it looks like the room has lights on. In fact, it is night outside, and the lights in the room are off.

Conclusion

You know, I believe that DR.J Professional AK-40 projector has 7500 Lumens brightness because it lights up the whole room.

The projection quality is also good. I want to recall that it is a Full HD native resolution projector. You will not even see the pixels at close range.

However, I noticed that for some reason the bottom right corner is blurry. The other corners of the projector are good. However, it is not a big problem.

I also like that this projector supports 5G Wi-Fi. You can connect Android or iOS smartphones to it.

In my opinion, DR.J Professional AK-40 is a very good projector for $180.
