Experience images of superlative quality with the HD31UST - and all from just 30 cm away from a smooth surface or screen. It's perfect for watching live sports in full 1080p resolution and for movie nights at home. With its high brightness and low latency, it is the ideal projector for playing action-packed games in any room.
A built-in speaker provides great sound, and the two HDMI inputs ensure a simple and quick setup. By connecting an HDMI dongle, such as Google Chromecast, Amazon Fire Stick, or Apple TV, it can also be transformed into a smart projector. This way, you can play games, stream videos, and share photos on a big screen in the comfort of your own home.
30 cm is measured from the back of the projector. Like all ultra-short throw projectors, the HD31UST requires an absolutely smooth surface to project the perfect image. Since most walls are not completely smooth, you may need to install a screen to prevent any image distortion. If that is not possible, using a short-throw projector that can produce a 100-inch image from just over 1 meter away is recommended.

Der Optoma HD31UST ist ein guter Ersatz für den Fernseher, gerade, wenn Sie noch analoge Quellen auf die große Leinwand bringen wollen gehört er zur ersten Wahl. Gegen gelegentliche Spielchen hat der Spezialist für kurze Projektions-Distanzen ebenfalls nichts einzuwenden, zur Not reichen zudem die integrierten Lautsprecher vollkommen aus.
