All-in-One Meeting Solution
The StarryHub is designed as a comprehensive, integrated meeting hub, offering everything needed for both physical and virtual meetings in a single device. With projection capabilities, built-in conferencing software, microphones, and a camera, it allows for seamless, device-free participation in meetings. It’s also compatible with popular platforms like Zoom and Microsoft Teams, enabling users to launch and manage meetings directly from the projector itself. This integration is intended to eliminate the need for complex setups in conference rooms, providing a streamlined solution for meeting setup, content sharing, and easy application navigation.
For those who prefer using external devices, the StarryHub includes HDMI and USB ports for direct connections, letting users retain their usual configurations. Additionally, a wireless dongle supports screen mirroring for added flexibility.
Unboxing
The StarryHub arrived in fairly standard professional packaging. Enough thought was put into it to give a good first impression, but it wasn’t overdone to the point where you’d feel like the box itself was part of the product experience. In recent years, elaborate packaging has become a trend for some consumer tech products, but CZUR kept things practical here.
The unit was packaged securely in protective foam in order to safeguard the projector during shipping. It also arrived double-boxed, which is a nice extra measure to ensure the product’s safety in transit. Overall, the packaging felt appropriate for what you’d expect from a business-focused device: professional, protective, and practical.
Setup
When deciding where to place the StarryHub, it is intended to be positioned between the display area and the meeting participants. This setup allows the rear-facing camera to capture everyone in the room effectively. With a short throw ratio of 0.8:1, it’s well-suited for most meeting rooms, providing a large, clear image without needing much distance. I found this throw ratio pretty ideal, delivering a good image size without requiring excessive space.
On initial startup, the StarryHub guides you through a typical setup process found in most connected devices. You’ll select a language, connect to Wi-Fi, and enter login details for a CZUR account if desired. It’s a nice touch that CZUR allows users to skip account login, which is especially beneficial in business settings. However, certain advanced features do require the app, so you’ll need to decide whether setting up a CZUR account is necessary for your needs.
One detail to note: to get past the first screen, you must use the remote in touchpad mode to select your language.
Screen Controls
The StarryHub includes both auto-focus and auto-keystone features. When the projector starts up, it will automatically adjust focus and keystone. It also re-runs these adjustments if the projector is moved significantly—for example, if someone bumps the table during a meeting.
Focus
Keystone
The auto-focus on this projector is quite effective, with a quick refocus button on the remote for any needed fine-tuning. The auto-keystone, on the other hand, primarily corrects large-scale errors and doesn’t fully perfect the image. Fortunately, CZUR includes manual controls for both focus and keystone adjustments. I’d recommend trying auto-keystone first, and if it doesn’t work for your setup, then adjusting manually. CZUR is aware that the keystone feature could be improved and is actively working on updates to enhance it in the future.
Useability
Since CZUR markets this device as a standalone meeting solution, let’s evaluate how intuitive and easy it is to navigate.
Interface and Menus
The projector’s operating system can best be described as “functional bare bones.” It includes only the essentials required to operate, offering limited customization options and additional features. While the OS doesn’t support a wide range of apps, it includes the core applications necessary for running meetings. Notably, the device supports native Windows apps like Teams and Office, which is a significant advantage for business users needing seamless workflow integration.
The settings menu reflects this pared-down approach. Basic controls are available for primary functions, highlighting the minimalistic nature of the OS. This can be both a strength and a limitation: fewer settings make navigation simpler, but the lack of customization options might limit the device’s adaptability. For instance, under the “Projector” heading, you’ll find settings for focus, keystone, and volume, but no picture controls or presets. This inability to adjust the image quality is, in my opinion, the device’s most notable shortcoming.
While I generally prefer an OS with more flexibility, I can see the value in this streamlined design, as it keeps things straightforward. Still, a bit more depth in settings would always be welcome. The home screen, however, has a clean layout that offers easy access to commonly used functions and apps, making navigation intuitive and efficient.
Remote
Let’s discuss the remote, which essentially functions as both a wireless trackpad and keyboard in one and is about the size of a smartphone. It connects to the projector via Bluetooth and automatically pairs after the initial setup. To recharge, you simply place it on top of the projector, which conveniently triggers the projector’s sleep mode, a thoughtful feature. The remote also has a physical on/off switch located on the back.
The top row of the remote includes several quick-action buttons for adjusting modes, volume, autofocus, input, home, and back functions. Using the mode button in the top left corner, you can switch between trackpad mode, which works like a standard computer trackpad for moving the cursor and clicking, and keyboard mode, which illuminates a full keyboard under the trackpad surface for easy typing.
I have to say, this remote was one of the most pleasantly surprising features of the device due to its ease of use. Remotes for these types of devices are often an afterthought, leading to a less-than-stellar experience which luckily wasn’t the case here. Navigating the projector, logging in, installing apps, and even typing all felt as seamless as using a regular computer. Hats off to CZUR, this remote truly improves on the typical display device remote.
Meeting Technology and Hardware
Let’s dive into the meeting hardware, as this device is meant to be more than just a projector; it’s designed as an all-in-one meeting solution.
Connection Options
The StarryHub offers all major screen-casting options including Chromecast, Miracast, AirPlay, and DLNA, providing excellent flexibility for various devices. I tested each of these options, which all worked smoothly and without any issues for displaying content and playing videos.
On the back, the StarryHub includes a variety of I/O ports for wired connectivity options. In addition to HDMI input, there is a wired lan connector, 1 x USB 3.0, and 1 x USB 2.0. These can be used to connect some wired devices. Along with the third party wireless systems there is a first party StarryHub dongle—referred to as the Click Drop—which brings even more versatility to its connection options.
Click Drop
The Click Drop allows any computer with a USB-C port to connect wirelessly to the projector, cutting down on setup complexity. For initial use, it needs to be plugged into the projector to complete the pairing process and receive firmware updates, but afterwards is ready for quick and instant use.
In my testing, the Click Drop connected within about 8 seconds after plugging it in and pressing the activation button. It’s one of the more seamless wireless connection devices I’ve used, even outperforming Windows’ built-in Miracast feature, which I often rely on in my day-to-day work. Currently, the Click Drop only supports USB-C for screen casting. Although it includes a USB-C to USB-A adapter, this seems to be for pairing purposes only, as I was unable to cast displays using the USB-A adapter.
The Click Drop performs well with video, transmitting both audio and video directly to the projector without any need for additional configuration. This simplicity is a definite advantage. Many wireless display devices require adjustments or can suffer from audio sync issues, but I didn’t experience any of that here. CZUR appears to have put effort into making this device genuinely plug-and-play for a straightforward user experience.
Split Screen Viewing
One of the more unique features of the StarryHub is its ability to simultaneously connect and display multiple devices. CZUR claims it can handle up to four screens at once, which is an impressive capability for a business display. I can see this being extremely useful for meetings where multiple people need to present content at the same time.
In my tests, I connected a Windows PC via Miracast and a MacBook Pro using Click Drop. The feature worked smoothly, displaying both screens side by side. This does reduce the size of each screen, so in smaller projection spaces, it may become harder to read fine details. Still, it’s helpful that devices can connect through different casting services without compatibility issues.
This feature feels like one of those tools you don’t realize you need until you’re in a situation where it becomes invaluable. It’s a clever addition that could make business meetings more engaging and collaborative.
Video
The rear camera on this device functions as the primary video recorder, intended for setups where the projector is positioned between the user and the screen. In a conference room setting, the camera’s location and field of view work well, capturing the user effectively when positioned about 0.5 meters behind it.
In terms of image quality, the camera is adequate—neither outstanding nor poor. It handles lighting adjustments and color balance effectively, though occasionally the image appears slightly washed out. The clarity is similar to a typical laptop camera: not as sharp as a dedicated webcam but clear enough for general conference use.
A notable feature of this camera is its speaker-tracking capability, which can be turned on or off in the settings. While I usually find speaker tracking gimmicky and unreliable, CZUR’s implementation impressed me. It accurately tracked my movement around the room at a natural presentation pace. Unlike other systems that adjust too quickly, resulting in a jerky and sometimes nauseating experience, this camera only repositions when the speaker nears the edge of the frame, reducing abrupt movements and creating a much smoother viewing experience. It also effectively handled different people talking and knew when to zoom out during discussions.
Microphone
The StarryHub is equipped with a six-microphone array embedded at the top of the device, providing 360º voice pickup to capture sound from all directions. It boasts a pick-up range of 8-10 meters, with a noise-cancellation feature that can be adjusted in the settings.
During testing, the microphone array consistently delivered clear voice capture, even as I moved around the room. Impressively, it picked up my voice from over 5 meters away without needing to raise it, maintaining clarity even with furniture partially blocking the line of sight. The AI optimization handled background noise well, ensuring that voices remained distinct, even with other speakers or music in the background. Overall, the microphone quality and effectiveness are quite robust, ideal for conference and group settings. It was the best distance microphone that I have used in this setting.
Speakers
Now, let’s examine the audio quality. Since the StarryHub isn’t designed for full-range audio reproduction (20 Hz–20 kHz), I tailored my listening tests to business scenarios, where vocal clarity is key. Alongside my usual audio tests, I sampled podcasts, audiobooks, and video calls to evaluate how well the speakers handle spoken content.
According to CZUR, the speakers are tuned to enhance vocal clarity, theoretically making voices more distinct in meetings. However, I found that rather than simply tuning for clarity, the audio seemed constrained to the mid-vocal range, creating a unique but limited listening experience. The vocal range came through clearly, free of the typical distortion seen with overdriven speakers, but the sound had a “curtained” quality—higher frequencies felt filtered, as if muffled behind a barrier. Lower-pitched voices also felt recessed compared to higher-pitched voices, which is expected given the limitations of compact speakers in reproducing lower frequencies.
Measurements confirmed my impressions, showing a limited output range of 200 Hz to 6 kHz when placed on a table. This explains the “curtain effect” I perceived, with the audio centered on the mid-range, leaving both bass and treble noticeably absent. While voices remained intelligible, they lacked natural resonance, and music sounded hollow with minimal bass or high-end detail. In essence, the StarryHub’s speakers are optimized for vocal clarity in business settings, but their limited range falls short for other audio needs.
Special Meeting Features
Two additional features that I would like highlight on the StarryHub show that CZUR really put some thought into improving conference room productivity:
- Peripheral Mode: This mode allows you to use the StarryHub’s camera and microphone as dedicated peripherals for your computer. By connecting the Click Drop to your computer, you can select the StarryHub as the video and audio source, without having to show your device’s screen. This turns the StarryHub into a wireless camera and microphone to use during meetings.
- Local Meeting Recording: An onboard app enables you to record audio, video, and screen content directly from the StarryHub. This feature provides a simple solution for documenting meetings without needing additional software, making it easy to review discussions and presentations later.
Image Quality
Let’s take a look at the StarryHub’s image quality. Since this is a business projector, color accuracy is secondary to brightness and sharpness, given that most of its content will center around text and visuals meant to be clear and readable.
Brightness
CZUR lists the projector’s brightness at 2200 ANSI lumens, but in my testing, the highest measurement I was able to achieve was 1500 ANSI lumens. Since the projector lacks picture controls, this is the only mode available for assessment.
The brightness is adequate for screen sizes up to 100″ in a well-lit room. Beyond that size, however, the image begins to wash out noticeably in brighter environments. For screens larger than 100″, I’d recommend reducing ambient light to maintain picture quality.
Contrast
The unit measured an on/off contrast ratio of approximately 630:1 and an ANSI contrast of 161:1, which aligns well with other projectors in this price range. These contrast levels are sufficient for viewing business material clearly and for making out details in videos during conference room settings.
The gamma closely follows a 2.1 curve, which ensures that the image has a balanced range of brightness and detail in bright rooms, making content easier to interpret. This consistency in gamma response is beneficial for presentations and meetings, as it makes the colors smoothly blend without banding allowing the visual to look natural even if the color is not perfect. Whether viewing documents, slides, or video content, the projector’s gamma and contrast performance deliver a reliable image quality that suits professional settings well.
Sharpness
Sharpness is a key factor here since a lot of meeting content includes text, and a lack of clarity would make reading difficult. Fortunately, I found the projector to be sufficiently sharp for the task. Even from a distance, I had no trouble distinguishing text, and with my glasses on, I could comfortably read a full-screen PDF with 12-point font from about 15 feet (5 meters) away. I tested this on both a projector screen and a white wall, and the sharpness held up well.
To get the best results, it is recommended to position the lens at a 90º angle to the screen surface. Otherwise, keystone correction might be necessary, which reduces the number of active pixels, and in turn, the effective resolution. This is true for all projectors. Overall, the StarryHub is impressively sharp for its 1080p resolution.
Here’s a look at the sharpness test pattern on my theater screen. Any vertical banding you see is due to the camera’s frequency interacting with the projector’s LED light source, and is not visible in person. Also, the texture you notice is from the screen material, not the projected image itself.
Color
Now, let’s examine the color performance of this projector. Since the StarryHub is a business-oriented device, precise color accuracy is not its primary goal, but it’s helpful to understand how it manages color output. CZUR doesn’t advertise a specific color space coverage for this projector, but it would be reasonable to expect REC 709 as a baseline.
During setup, I immediately noticed a pronounced blue and green tint, with 100% white leaning teal, a typical characteristic of non-cinema projectors where brightness is more important than color accuracy. This is because the red channel is often the limiting factor when it comes to brightness as it is the hardest to make brighter. This impression was confirmed by measuring the white point, which registered at 9300K compared to the standard 6500K, and analyzing the REC 709 color space, where the average deltaE across 56 test points was around 15. Given the cooler white point, an average deltaE of 15 is within an acceptable range, but does indicate visible color deviation.
All measurements were taken using the i1Display Pro colorimeter, HCFR software, and a 4K Soundmax XY-Screen.
The key consideration is whether this color shift impacts typical business content. For most non-color-critical presentations, the color bias won’t detract from the experience. However, for color-sensitive tasks, I’d advise against using this projector without an external calibration device, as it doesn’t provide the accuracy needed for work that demands faithful color representation.
Calibration
Normally, this is where I’d dive into the projector’s image settings, adjusting the picture modes and fine-tuning custom settings for a more accurate display. However, this projector has no picture controls at all. Given its design as a business projector, it’s understandable that the focus may not be on color accuracy, as most users in office settings may not require it. Still, a basic level of picture customization would be a welcome addition.
Without any picture adjustment options, you’re left with the factory calibration, meaning what you see is what you get right out of the box. This might feel limiting to those who are used to some degree of picture control.
Here are pictures of the expected image of the StarryHub projected on my theater screen and a white wall.
Images 1-5 displayed on projector screen, Images 6-7 displayed on white wall. All images were taken on a Google Pixel 4A5G.
If color accuracy is critical for your tasks, I recommend connecting a computer via HDMI and using an ICC profile for display calibration. This can help achieve a closer match to accurate color, though it’s worth remembering that ICC profiles are specific to the display and the computer used.
Conclusions
The CZUR StarryHub offers a thoughtful all-in-one solution for business settings, bringing together a projector, conference camera, microphone array, and connectivity tools in a compact device. The ease of setup, wireless screen-casting options, and multi-screen capability make it well-suited for dynamic meeting environments, reducing the usual technical hurdles that can disrupt presentations. The Click Drop feature, in particular, adds an impressive layer of convenience by simplifying wireless connections.
While the StarryHub’s streamlined OS is easy to navigate, its limited customization options may be a drawback for those seeking more control over image quality. The audio, while clear and focused on vocal clarity, may fall short for users who need broader sound fidelity. In terms of projection quality, the StarryHub performs capably for business applications, though users with larger or more brightly lit spaces might need to adjust their setup for optimal results.
Overall, CZUR’s StarryHub is a practical and versatile tool for business and conference environments, excelling in user-friendliness and essential meeting features. While not without its limitations, it effectively addresses the core needs of a modern conference room setup, helping to simplify and improve meeting experiences.
