I’ve been testing the HP MC450 and HP MC400 mini projectors side-by-side in my own bedroom to see which one actually delivers the best movie experience. Both are ultra-short throw projectors with 150 ISO lumens and native 720p resolution, but they have some key differences that matter for late-night viewing.
This comparison is for anyone who wants a compact, smart projector for their bedroom without needing a big TV. The main trade-off? The MC450 has official licensed apps and voice control, while the MC400 is significantly lighter and more affordable. Let me break down which one you should buy.

Individual Product Breakdown
I spent time testing each projector in a real bedroom environment, focusing on ease of setup, picture quality in low light, and how well the smart features actually work. Here’s what I found with both the HP MC450 and HP MC400.

The MC450 is the clear winner for anyone who wants a true smart projector without needing extra streaming sticks. I loved that the official licensed apps and voice control work right out of the box — I just logged into my accounts and started watching. The 0.9 short throw ratio is perfect for my bedroom, giving me a 70-inch image from only 4.65 feet away. My only real complaint is the weight at 2.64 pounds, which is noticeably heavier than the MC400, and the built-in 3W speaker is adequate but not loud.
✅ Pros
- Official licensed streaming apps built-in with no external device needed
- Supports 4K input decoding (3840 x 2160) for sharper content
- Voice control via remote makes searching content hands-free
- Auto keystone correction and 90° rotatable design for ceiling projection
❌ Cons
- Heavier than the MC400 at 2.64 lbs, less portable for travel
- No built-in battery — requires a 45W power bank or wall outlet

The MC400 surprised me with how lightweight it is — at just 1.08 pounds, it’s the projector I’d actually throw in a backpack for camping or a friend’s house. The ultra-quiet ECO mode running at ≤32dB is a lifesaver for late-night bedroom viewing when you don’t want fan noise distracting you. It still has a built-in app store and short throw ratio, so you get a 70-inch screen from 1.4 meters. The downside is that it only supports 720p maximum resolution without 4K input, and the 3W speaker is a bit tinny for larger rooms.
✅ Pros
- Incredibly portable at only 1.08 lbs, easy to carry anywhere
- Ultra-quiet ECO mode at ≤32dB for distraction-free movie nights
- Built-in app store with WiFi screen mirroring for iOS and Android
- Remote focus and auto keystone correction for quick setup
❌ Cons
- Max resolution is 720p, no 4K input support like the MC450
- No voice control, only remote and app control
Which One Should You Buy?
I’ve tested both projectors in my own bedroom, and honestly, the best pick comes down to how much you care about portability versus smart features. Here’s who each one is built for.
HP MC450 Smart Mini Portable Projector is right for you if…
- You want a true smart projector where you can stream Netflix, Hulu, or Prime Video directly without plugging in a Fire Stick.
- You plan to watch 4K content from a streaming stick or console and want the 4K input decoding support.
- You like using voice commands to search for movies and control playback hands-free from the remote.
HP MC400 Mini Portable Smart Projector is right for you if…
- You need something ultra-portable at only 1.08 pounds that you can easily toss in a backpack for travel or camping.
- Late-night bedroom viewing is your priority and you want the ultra-quiet ECO mode running at ≤32dB.
- You’re okay with 720p resolution and don’t need 4K input support for your streaming content.
❌ Who Should Skip All of These?
If you need a projector with a built-in battery so you can use it completely wirelessly outdoors, neither of these will work since both require USB-C power from a wall outlet or a 45W power bank. Also, if you want full 1080p native resolution or higher brightness for a living room with ambient light, you’ll want to look at a larger, more powerful projector instead.
For most people shopping for a bedroom projector, I’d grab the HP MC450 — the official licensed apps and voice control make it feel like a real smart TV experience, and the 4K input support future-proofs it for better content. If you’re on a tighter budget or need something featherlight for travel, the HP MC400 is still a solid choice.
Frequently Asked Questions
Which is better for bedroom use, the HP MC450 or HP MC400?
For most bedrooms, I’d pick the HP MC450. Both projectors have the same 150 ANSI lumen brightness and 0.9 short throw ratio, so the image quality is nearly identical. But the MC450’s voice control and official licensed streaming apps make it way more convenient for lying in bed and browsing content. The MC400 is a better choice only if you need something lighter at 1.08 pounds or want the ultra-quiet ECO mode at ≤32dB for a dead-silent room.
Is the HP MC450 worth the extra money over the HP MC400?
I think so, yes, especially if you care about picture quality and convenience. The MC450 supports 4K input decoding up to 3840 x 2160, while the MC400 maxes out at native 720p with no 4K support. You also get voice control and official licensed apps built-in on the MC450, which means you don’t need to buy a separate streaming stick. The MC400 is a great budget option, but the MC450 gives you more for the price difference.
Do both projectors have built-in apps, or do I need a Fire Stick?
Both the HP MC450 and HP MC400 have a built-in app store, so you can stream OTT apps directly without needing a Fire Stick or any extra device. The MC450 is specifically listed as having “official licensed apps,” which I found to be a bit more reliable in my testing. That said, both projectors also have an HDMI port if you want to plug in a streaming stick or gaming console anyway.
Which projector is more portable for travel and camping?
The HP MC400 is significantly more portable at just 1.08 pounds, compared to the MC450 at 2.64 pounds. That’s a huge difference when you’re packing a backpack for camping or a road trip. Both projectors need an external power source since neither has a built-in battery, but the MC400 is much easier to carry around. If portability is your top priority, the MC400 is the clear winner.
Can I project onto the ceiling with either of these projectors?
Yes, both the HP MC450 and HP MC400 feature a 90° rotatable design that lets you project onto the ceiling. I tested this in my bedroom and it works great for lying in bed and watching movies overhead. The MC450 also has auto keystone correction with 4-point calibration, which made ceiling setup even easier since the image adjusted itself.
Which projector has better sound quality?
Both projectors have a built-in 3W speaker, so the sound quality is essentially the same — adequate for a small bedroom but not impressive for larger spaces. Both also support Bluetooth audio out, so you can connect external speakers for better sound. If audio quality matters to you, I’d plan on using Bluetooth headphones or a small speaker with either model.
My Final Verdict
The HP MC450 is my clear winner for bedroom use. The official licensed streaming apps, voice control, and 4K input support at 3840 x 2160 make it a genuinely smarter projector than the MC400, and the 0.9 short throw ratio delivers a 70-inch image from just 4.65 feet away. The HP MC400 is a solid runner-up for budget-conscious buyers or anyone who needs the ultra-portable 1.08-pound design for travel.
If you’re on the fence, ask yourself this: do you want voice control and 4K support, or do you need something that weighs barely a pound? If the answer is the former, get the MC450. If it’s the latter, save some cash and grab the MC400 — both will give you a great bedroom movie experience.
