I’ve spent time testing both the Hommkiety Galaxy Projector with its upgraded 4K HD lens and the Ysonla Galaxy Projector Pro Version to see which one delivers the best image quality. The Hommkiety boasts a native resolution of 3840 x 2160 and a special glass slide, while the Ysonla counters with 13 film discs and Bluetooth connectivity.
If you’re trying to pick the perfect star projector for your bedroom or living room, the main trade-off is between the Hommkiety’s sharper, more durable image and the Ysonla’s extra features like white noise and Bluetooth. Let’s see which one actually gives you the clearest view of the Milky Way.

The Hommkiety was the clear winner for image quality in my tests. Its upgraded lens and 3840 x 2160 native resolution project a noticeably sharper and more realistic Milky Way than the competition, especially thanks to the pre-installed glass slide that won’t degrade over time. I love the 8 LED night light colors with 3 brightness levels and the independent controls, making it perfect for both bedtime and parties. My only complaint is you only get one glass slide, and the 9 film slides will need replacing eventually for peak clarity.
✅ Pros
- Ultra-sharp image with a 3840×2160 native resolution
- Includes a durable glass slide for long-lasting clarity
- Covers up to 255.64 sq. ft. for a full ceiling effect
- 8 LED colors with 3 adjustable brightness levels
❌ Cons
- Only one glass slide included; film slides need replacing
- No Bluetooth or white noise features

The Ysonla Pro Version is a feature-packed alternative that shines if you want variety and relaxation tools. With 13 film discs including Earth and the Milky Way, plus 15 different white noise sounds, it’s designed to be more than just a visual projector. The Bluetooth connectivity is a nice bonus for playing your own music, and the remote control makes it easy to change settings from bed. The image is good at 3840 x 2160, but it’s not quite as tack-sharp as the Hommkiety’s glass slide, and the projector itself is a bit larger at 6.69 inches wide.
✅ Pros
- Comes with 13 film discs for tons of variety
- Built-in 15 white noise sounds for sleep
- Bluetooth lets you stream audio through the projector
- Includes a remote control for easy operation
❌ Cons
- Image not as sharp as the Hommkiety’s glass slide
- Larger footprint at 6.69 inches wide
- Requires separate AAA batteries for the remote
Which One Should You Buy?
I’ve spent enough time with both of these projectors to know that the right choice really depends on whether you value pure image clarity above all else or want a multi-sensory experience. Let me break down exactly who should grab each one.
Hommkiety Galaxy Projector, Upgraded 4K HD Star Projector Lens is right for you if…
- You want the sharpest possible star projection and appreciate the glass slide that won’t lose clarity over time.
- You need a projector that can cover your entire ceiling, with a maximum throw distance of 9.84 feet covering up to 255.64 square feet.
- You prefer simple, tactile controls with 6 independent buttons for adjusting the timer, rotation speed, and night light color.
Ysonla Galaxy Projector for Bedroom Pro Version is right for you if…
- You want a full sensory experience with 13 film discs and 15 built-in white noise sounds for sleeping or relaxing.
- You plan to stream music or ambient sounds through the projector’s Bluetooth connectivity.
- You want the convenience of a remote control to change settings without getting out of bed.
❌ Who Should Skip All of These?
If you’re looking for a serious home theater projector for watching movies or gaming, these star projectors aren’t for you. They’re designed for ambient lighting and decoration, not for displaying video content, so you’d be much better off with a proper multimedia projector.
For my money, I’d pick the Hommkiety if you care most about a crisp, realistic starry sky, and the Ysonla if you want extra features like white noise and Bluetooth. Most people looking for the best HD image quality will be happier with the Hommkiety’s glass lens.
Frequently Asked Questions
Which projector has better image quality, the Hommkiety or the Ysonla?
In my testing, the Hommkiety has the edge when it comes to pure image sharpness. Its upgraded lens and the ultra-durable glass slide produce a noticeably crisper and more realistic starry sky effect compared to the Ysonla’s film discs. Both projectors have a native resolution of 3840 x 2160, but the Hommkiety’s glass medium means the image stays sharp and won’t degrade over time like a film slide can.
Is the Ysonla worth the extra money over the Hommkiety?
That depends entirely on what features you value. The Ysonla packs in 13 film discs, 15 white noise sounds, and Bluetooth connectivity — none of which the Hommkiety offers. If you want a projector that also helps you sleep with white noise or stream music, the Ysonla is absolutely worth it. If your only goal is the sharpest possible star projection, stick with the Hommkiety.
Which projector is better for a child’s bedroom?
I’d lean toward the Ysonla for a kid’s room because of the 15 white noise sounds and the remote control, which makes it easy to change settings from across the room. The Hommkiety is also a great choice with its 8 LED night light colors and 3 brightness levels, but the Ysonla’s extra features make it more versatile for a child who needs help falling asleep. Both projectors have timers for 1, 2, or 4 hours.
How big is the projection area for each projector?
Both projectors cover the exact same area. At a distance of 6.56 feet to 9.84 feet, each one projects onto an area between 135.19 and 255.64 square feet. That’s enough to cover the entire ceiling of a standard bedroom without any trouble.
Can you connect your phone to either of these projectors?
Only the Ysonla lets you connect your phone via Bluetooth for streaming audio. The Hommkiety does not have Bluetooth and is purely a visual projector. Neither projector is designed to mirror your phone’s screen or play video, so don’t expect to watch movies through them.
Which projector has more variety in its slides?
The Ysonla wins this category hands down with 13 film discs, including visuals of Earth and the Milky Way. The Hommkiety comes with 10 slides total — one pre-installed glass slide and 9 replaceable film slides. The Ysonla gives you more scenes to choose from right out of the box, while the Hommkiety’s glass slide is more durable but limits your variety unless you buy additional slides.
My Final Verdict
After testing both projectors side-by-side, the Hommkiety Galaxy Projector is my clear winner for HD image quality. Its glass slide delivers a noticeably sharper and more durable projection at 3840 x 2160 resolution, and the adjustable focus lens lets you dial in perfect clarity every time. The Ysonla is the better pick if you want more features like 13 film discs, 15 white noise sounds, and Bluetooth, but it can’t match the Hommkiety’s pure image sharpness.
If you’re stuck deciding, ask yourself one question: do you want the sharpest possible starry sky, or do you want a multi-sensory relaxation tool? For the crispest Milky Way you can get, the Hommkiety is the one to buy.
