Xgimi Horizon Pro 4K projector review: Beautiful new world

In the default settings, there is perceptible input lag when the projector is connected to a laptop via HDMI. We noticed a considerable latency as soon as we started moving the mouse cursor.

However, Xgimi advertises on the product page that the Horizon Pro has a super low latency of “just” 35 ms. The secret here is MEMC: this technology estimates and inserts a picture between two frames, for example, to make motion appear smoother. As a result, a 24 fps video will look more like 50 to 60 fps and feel much silkier. This isn’t an issue when you’re watching films and can have a positive impact depending on your visual preferences. For games, though, the computation between frames causes the aforementioned latency.

Fortunately, there are two ways to turn off this feature, both of which are accessible via Image Mode in the settings. We recommend switching from Default to Game. Alternatively, you can go over to Custom mode, where you can also fine-tune a few other settings and find MEMC tucked away in the Motion Compensation option at the very bottom. You should definitely disable it when gaming because doing so will indeed reduce lag to a hardly noticeable level and also make games very playable. That said, advanced gamers may still be able to detect a tiny amount of lag in very fast-paced shooters.
