REVIEW – I’ve reviewed a few 1080p projectors, and for the most part, I’ve been pleased with them. Along came the Dangbei Mars Pro 4K projector, and I just had to check out the highly-rated Dangbei Mars Pro 4K projector. 4K resolution and a laser have to be better, right?

Design and features

The Dangbei Mars Pro 4K Projector was packaged well in a sturdy custom box. It had excellent foam protection. The unit itself did not disappoint, being a stylish aluminum frame and almost all-black design.

There are no controls on the unit itself besides a power button, so you’ll need to use the included remote control to operate it. The remote is RF, so you don’t have to point it at the unit for it to work. You’ll also need an HDMI cable, as this one does not come with one, unlike other projectors.

I immediately noticed that the projector does not include any level/tilt mechanism. It does have a threaded PTZ mount on the bottom so that you can mount it with a 1/4-20 screw to a projector mount or tripod head. I chose a tabletop tripod that I had, but I intend to mount a standard tripod head to the top of my “backyard mobile movie box” that I built a couple of summers ago.

My table top tripod could hold the projector, but a larger tripod would be better.

The User Manual was quite lacking. It covers the basics of projection distances, projector components and ports, remote button usage, remote pairing, network setup, focus and keystone settings, and Bluetooth speaker mode. However, there needs to be more information about the various settings and screens in the software. Although most of the things in the software are self-explanatory, a few things would have been nice to have explained.

The secondary screen, when “scrolling” down

I turned on the Dangbei Mars Pro 4K Projector, and the autofocus feature automatically focused the image. This was a very nice feature, as with my poor eyesight, focusing on the image has always been a challenge. There is also a manual focus feature that you operate with the remote control. Whenever you move the projector, it will re-adjust the focus automatically.

In this image, I have lightened the non-image area, as it was dark in the room.

The Auto Keystone correction works very well, adjusting the image up to 40 degrees. The intelligent obstacle avoidance also detects if the projected image is off your screen or if an object is in the way and resizes the image to fit automatically. I thought this was a brilliant feature. The manual keystone correction also works very well to fine-tune where you want the projected image.

As far back as I could go in my office (about 10 ft), the image just fits on my 100″ screen

The picture itself is very good. The clarity is better than the previous projectors that I’ve reviewed. There are presets for various picture settings, like Standard, AI Picture, Vivid, Movie, Game, and Custom. Custom controls include brightness, contrast, saturation, sharpness, and Hue. The MEMC (Motion Estimation, Motion Compensation) can meet an adaptive refresh rate of up to 120Hz.

Overall, the image is extremely good.

The audio is excellent; it has a fair amount of bass/depth to the sound, unlike cheaper projectors that have a tinny sound. The sound settings include options for Standard, Music, Cinema, and Sports. The is an audio output option for a speaker or eARC/SPDIF.

There is a screensaver option also. The screensaver has three available modes: Static, Dynamic, and Digital Clock. My favorite is the Dynamic mode which has short video clips of scenic locations from around the world. There is also a wallpaper setting for the background of the main screen. There are a lot of pre-installed images from categories such as football, ocean, lake, artwork, etc.

The menu/operating system is very good, however, I did find some things that don’t work. I could not get the Cast feature to work with my iPhone. The projector just never shows up in my list of devices on my iPhone when trying to send it via airplay. I have no problem using airplay with my TV. Dangbei sent a Hako mini Android TV dongle along with the projector, but this just seems a bit ridiculous. I already have enough cords and remotes for the DVD player and projector, I don’t want more for the Android TV thing. This is incredibly annoying since the screenshots on the Amazon listing show Prime Video, YouTube, Hulu, and Netflix apps – all of which are not preinstalled on the device.

The YouTube app worked great

I did find in the Community section that you can install the Emotn store, which you can then load apps such as YouTube, Prime Video, Netflix, etc. However, there are reports of some of these not working. I found YouTube usable. However, Amazon Prime was unusable. I could get it to load and run, however, there was no indication of where the focus was in the navigation, so you can’t navigate to click on things, such as to play a movie.

The Dangbei Butler app is handy. It shows how much storage is available, how much RAM is being used, and has utilities for boost, cleanup, testing, and file management.

The Browser app is useful if you want to pull up a website. The remote control includes a mouse option that makes navigating website links fairly easy. I wouldn’t want to do a ton of surfing on it, but for a presentation or a quick view of a website, it appears to work great.

What I like

  • Clarity and brightness
  • Menu System
  • Video Screensavers
  • Wi-Fi
  • Quiet

What I’d change

  • No built-in streaming apps
  • Cast feature needs to work
  • Needs some type of leveling feet
  • Manual is very limited, I would have preferred to have at least a summary of menu items

Final thoughts

The Dangbei Mars Pro 4K Projector has been a love-hate item for me. I love the picture quality, brightness, auto-focus, and auto-keystone. However, I hate the fact that some of the streaming apps you can download don’t work properly. I mostly watch movies on DVD or from Prime Video, so I’m sure I’ll enjoy it very much this summer. However, for a projector in this price range, it really should have better support for apps that stream.

  2. Don’t spend good money on crap products!! 😅😅
    For $500 more you can get a 4K Epsom 9400 that would wipe the floor with this thing. You don’t need smart stuff built into a projector, it’s just more things to go wrong! Better to spend the money on picture quality rather than gimmicks!

    1. Is anyone who’s setting up a home cinema and spending this amount of money playing the sound out of the projector? Make the box smaller and cheaper, or smaller and better quality. I’ll provide the amp and speakers.

  3. This uses the .47 inch pixel shift tech from Texas Instruments DLP. It’s not Native 4k. The BenQ X3000i uses the bigger .67 inch Ti Chip. I love my X3000i!

  4. Im not tech savy and need to know what your advice would be on a around 300.00 dollar range. The best all around way to go. Maybe with powered speakers? Etc. I would appreciate any help you could give me. I cant afford the laser projector at this time. Thankyou
