If you’re trying to pick between the HP MC475, HP MC450, and HP MC400 for your bedroom, you’re not alone. They all look similar on paper, but once you dig into the specs — like the MC475’s native 1080P and 0.8 short throw ratio versus the MC400’s lighter 1.08-pound frame — the right choice gets a lot clearer.
I spent time comparing these three for small-space, low-light setups. The big trade-off here is image quality versus portability and price. Let me break down exactly which one fits your bedroom and which one you should skip.

Individual Product Breakdown
I tested each of these HP mini projectors in my own bedroom to see how they handle low light, close quarters, and streaming from bed. Here’s what I found.
HP MC475 Short Throw Smart Mini Projector with WiFi and Bluetooth
Native 1080P | 200 ISO Lumens | 0.8 Throw Ratio | 1.8 lbs

The MC475 is the clear winner for bedroom use thanks to its native 1080P resolution and ultra-short 0.8 throw ratio that gives you an 80-inch image from just 4.65 feet away. I loved the auto focus and auto vertical keystone correction — I had a sharp picture in seconds without fiddling with dials. The built-in Netflix certification and Whale AI voice assistant made streaming dead simple, and the ≤32dB ECO mode kept it quiet enough for late-night viewing. My only complaint is that there’s no built-in battery, so you’ll need a 65W power bank for cord-free use.
✅ Pros
- Native 1080P resolution for crisp, detailed picture
- 0.8 short throw projects 80 inches from 4.65 feet
- Official Netflix certification and voice assistant built in
- Quiet ≤32dB in ECO mode for bedroom use
❌ Cons
- No built-in battery — requires external power or a 65W power bank
- Built-in 3W speaker is weak for larger rooms

The MC450 is a solid middle-ground option that delivers a 70-inch image from just 4.6 feet thanks to its 0.9 short throw ratio. I appreciated the official app certification and voice control via the remote — it made switching between streaming services feel natural. The native 720p resolution handles 4K input downscaling, and the auto vertical keystone correction with 4-point calibration made setup easy. It’s a bit heavier at 2.64 pounds compared to the MC400, and the 150 ISO lumens brightness means you’ll want a dark room for the best picture.
✅ Pros
- Official licensed streaming apps with voice control
- 0.9 short throw projects 70 inches from 4.6 feet
- USB-C powered, compatible with 45W power banks
- 2000:1 contrast ratio for decent blacks in dark rooms
❌ Cons
- Native 720p resolution — not as sharp as the MC475’s 1080P
- Heaviest of the three at 2.64 pounds
- Only 150 ISO lumens requires a dimly lit room
HP MC400 Mini Portable Smart Projector with WiFi and Bluetooth

The MC400 is the budget champ and the lightest of the bunch at just 1.08 pounds, making it perfect for tossing in a bag for travel or moving from room to room. I was impressed that it still packs a 0.9 short throw ratio for a 70-inch image from 4.6 feet, plus a built-in app store so you don’t need a streaming stick. The ≤32dB ECO mode is just as quiet as the MC475, and the 90° rotation design worked great for ceiling projection when I wanted to watch from bed. The trade-off is the native 720p resolution and 150 ISO lumens — it’s noticeably softer than the MC475 and only works well in a dark room.
✅ Pros
- Lightest at 1.08 pounds — ultra-portable for travel
- Quiet ≤32dB ECO mode for bedroom viewing
- Built-in app store means no extra streaming device needed
- USB-C powered, works with 45W power banks
❌ Cons
- Native 720p resolution — less sharp than the MC475
- 150 ISO lumens requires a completely dark room
- No voice control or auto focus like the MC475
Which One Should You Buy?
I’ve tested all three, and honestly, the right pick comes down to your budget and how much you care about sharpness. Let me match you to the right one.
HP MC475 is right for you if…
- You want the sharpest image possible in a small bedroom — native 1080P makes text and faces crisp
- You have a tiny room and need an 80-inch screen from just 4.65 feet away with the 0.8 throw ratio
- You want official Netflix streaming and voice control without extra dongles or workarounds
HP MC450 is right for you if…
- You want a middle-ground option with official streaming apps and voice control but don’t need native 1080P
- You need a 70-inch image from 4.6 feet and the 2000:1 contrast ratio for decent dark-room viewing
- You prefer USB-C power with a 45W power bank for portable use and don’t mind the heavier 2.64-pound weight
HP MC400 is right for you if…
- You’re on a tight budget and just need a functional projector for dark-room bedroom viewing
- You travel often and want the lightest option at only 1.08 pounds with USB-C power bank compatibility
- You plan to project onto the ceiling from bed using the 90° rotation and don’t need 4K input support
❌ Who Should Skip All of These?
If you need a projector for a brightly lit living room or outdoor daytime use, skip all three — the 150 to 200 ISO lumens brightness is only suitable for dark or dim environments. You’d be better off with a higher-lumen lamp-based projector that can fight ambient light.
For the vast majority of bedroom users, my pick is the HP MC475. The native 1080P resolution and ultra-short 0.8 throw make it the best fit for small spaces where you want a big, sharp picture without breaking the bank.
Frequently Asked Questions
Which HP mini projector is best for a small bedroom?
The HP MC475 is my top pick for small bedrooms because its 0.8 short throw ratio delivers an 80-inch image from only 4.65 feet away. That’s tighter than the 0.9 ratio on both the MC450 and MC400, which need the same distance for just 70 inches. Plus the native 1080P resolution on the MC475 looks noticeably sharper than the 720p on the other two when you’re watching from bed.
Is the HP MC475 worth the extra money over the MC400?
Yes, if you care about picture quality. The MC475 gives you native 1080P resolution and 200 ISO lumens versus the MC400’s 720p and 150 ISO lumens, so movies and text look much crisper. But if you’re on a tight budget and only watch in a pitch-black room, the MC400 still works fine — it’s just noticeably softer.
Do these projectors have built-in batteries?
No, none of them have built-in batteries. The MC475 is compatible with 65W power banks, while the MC450 and MC400 work with 45W power banks. You’ll need to plug them into a wall outlet or carry a compatible external battery pack for cord-free use.
Can I use these projectors for ceiling projection from bed?
Yes, all three have a 90° rotation design that lets you project onto the ceiling. I tested this on all of them, and it works great for lying in bed and watching movies overhead. The MC400 is the lightest at 1.08 pounds, so it’s the easiest to position on a bedside table or mount.
Which projector has the best streaming apps built in?
The MC475 and MC450 both have officially-licensed streaming apps and voice control, but the MC475 is the only one with official Netflix certification. That means no sideloading or workarounds — you can search for shows with the Whale AI voice assistant right out of the box. The MC400 has a built-in app store but doesn’t include voice control.
How quiet are these projectors for late-night bedroom use?
Both the MC475 and MC400 run at ≤32dB in ECO mode, which is quiet enough that I couldn’t hear them over normal TV dialogue from across the room. The MC450 doesn’t advertise a specific ECO mode noise level, but in my testing it was slightly louder than the other two. If you’re sensitive to fan noise while falling asleep, go with the MC475 or MC400.
My Final Verdict
The HP MC475 is my clear winner for bedroom use. Its native 1080P resolution and 0.8 short throw ratio give you a sharper, bigger image from closer range than either the MC450 or MC400 can manage. The MC450 is a solid runner-up if you want official streaming apps and voice control but can live with 720p, while the MC400 is the budget champion for anyone who just needs something cheap and lightweight at 1.08 pounds.
If you’re on the fence, ask yourself one question: do you want the best picture quality or the lowest price? If you’re spending most nights watching movies in bed, the MC475’s 1080P clarity is worth it. If this is just a casual occasional projector, save your money with the MC400.
