help Optoma UHD42 FAQ

How bright is the Optoma UHD42?

Optoma's European UHD42 documentation lists 3,400 ANSI lumens, so the often-repeated 3,000-lumen figure is not the specification I would use for this model. It is designed for home entertainment and gaming in rooms that are not fully dark.

Can the Optoma UHD42 accept 4K and run games at 240Hz?

It supports a 4K UHD signal and offers 1080p at 240Hz, with an input-lag figure of 15.7ms in Optoma's product material. The high-refresh mode is therefore a 1080p gaming feature, not 4K/240Hz output.
