Bright living-room projector

The BenQ TH575i is a DLP home-theatre projector built for bright rooms and casual gaming. Its 3800 ANSI lumens output lets a 120 image stay visible with lights on. A licensed Google TV dongle adds Netflix, YouTube and Disney+ without extra boxes. The 16.7 ms input lag keeps fast games responsive.

Sustained brightness and lamp life

In Normal mode the lamp runs for 6000 hours; SmartEco and ECO modes extend that to 10000 hours, while LampSave reaches 15000 hours. The 295 W typical draw at 110 V remains steady during long sessions. Auto vertical keystone up to 40 degrees and 1.1x optical zoom keep the image square without constant readjustment.

HDMI 1.4a connectivity limits

The single HDMI 1.4a port with HDCP 1.4 caps external sources at 1080p 60 Hz and blocks 4K or HDR pass-through. Audio must leave through the 3.5 mm jack or the 10 W internal speaker. The USB Mini-B and RS-232 ports serve service and control only, not media playback.

Questions about this item

How much heat and power will the 295W projector add to a room during an all-day movie marathon?

Typical power draw is 295W at 110V, so the unit adds roughly that much heat to the space; lamp life reaches 6000 hours in Normal mode, 10000 hours in SmartEco or ECO, and 15000 hours in LampSave mode.

The box includes a Google TV dongle — does it need a separate HDMI port and USB power to work?

The dongle plugs into the single HDMI 1.4a port; power comes from the USB Mini-B socket on the projector, so no extra wall adapter is required.

Will my older 1080p laptop with HDMI 1.4 output drive the 1.49–1.64 throw ratio and 16.7ms lag without issues?

Yes — the HDMI 1.4a input accepts 1920×1080 at 60Hz, the 1.1× optical zoom covers the 1.49–1.64 throw range, and the 16.7ms input lag applies to that signal.
