Significant Performance Boosts

• True 4K Resolution: Unlike the previous models, the U1 has a Physical (Native) Resolution of 3840x2160 (4K). This provides four times the detail of the 1080p F1 model.

• Superior Brightness: It outputs 800 ANSI Lumens (marketed as 8000 lumens). This is a massive jump from the F1's 350 ANSI lumens, making the image much more vibrant and usable in rooms that aren't perfectly pitch black.

• Better Software & Streaming: It runs Android 11 via a certified Netflix 4K Dongle. This is crucial because many budget projectors struggle to play Netflix in high resolution due to licensing; this model is built specifically to handle it.

• Memory & Speed: It offers 2GB or 3GB of RAM, which will make the interface much smoother and more responsive than the 1GB found in the O1 and F1 models.

Audio & Setup

• Enhanced Sound: The U1 features dual 8W speakers ($8W*2$) with HIFI STEREO, providing a much fuller soundstage than the single 6W or basic built-in speakers of the smaller units.

• Advanced Correction: It includes Auto Focus and Auto Keystone Correction, but adds an adjustable holder to help you physically angle the projector more easily.
