When shopping for a 4K projector in the UK, here are a few things to consider:

-
Smart Features: Android TV or Google TV saves you from needing extra devices.
-
Size and Portability: Smaller flats may benefit from compact or all-in-one designs.

Audio Quality: Built-in speakers are a bonus, but external sound is often better.
FAQ
Can I use a 4K projector during the day in a bright room?
It depends on the projector’s brightness level (measured in lumens). Models like the Cosmos Laser 4K (2,200 ANSI lumens) perform well in moderately lit UK rooms. For bright daylight settings, consider using blackout curtains for the best image quality.
Do I need a screen to use a 4K projector at home?
While a projector screen will enhance image clarity and colour accuracy, all Nebula projectors—including the X1 and Cosmos models—can project onto plain white walls. For optimal results, especially with 4K content, a dedicated screen is recommended.
Do I need Wi-Fi to use a 4K projector in the UK?
Wi-Fi is required for streaming content from platforms like Netflix, Disney+, and YouTube. However, you can also connect external devices like Blu-ray players, game consoles, or USB drives via HDMI or USB for offline playback.
