Our take
Consider the BenQ W770ST when the screen and seating leave little space for a conventional lens. BenQ documents a short 0.72–0.87:1 throw, native 720p, and 2,500 ANSI lumens, making room geometry its clearest selection advantage.
Home video in a room where a short-throw position matters more than Full HD detail.
It is not a match for buyers who require native Full HD or 4K detail, integrated streaming, or documented ultra-short-throw placement.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The 0.72–0.87:1 ratio reduces lens-to-screen distance compared with standard-throw models.
- BenQ specifies 2,500 ANSI lumens and a 1.2× zoom.
- HDMI and legacy video inputs support a range of external source equipment.
What to weigh up
- Native 1280 × 720 is below Full HD and 4K image formats.
- Accepted 1080p signals do not change the projector's native resolution.
- The 210-watt lamp and used-unit hours need checking before purchase.

What the features mean for you
Short throw solves one room problem
BenQ gives the W770ST a 0.72–0.87:1 throw range. That shorter lens can help when a projector must sit closer to the screen than a conventional home model, such as on a table near a wall or in a room with limited mounting distance. Measure the desired image width and projector position against the manual before deciding that the lens will fit. The W770ST is short throw, not automatically an ultra-short-throw model, so do not apply a close-wall assumption intended for UST equipment.
Native 720p is a deliberate compromise
The model's native resolution is 1280 × 720. The manual describes accepted 1080p signals, but input compatibility does not make the displayed panel Full HD. This may be enough for casual video in a room where placement is the main constraint; it is a compromise for fine text, detailed game graphics, and newer high-resolution sources. If the picture's pixel detail matters more than projection distance, compare it with the Full HD HT3050 or another higher-resolution home model.
Use the ANSI figure as a comparison point
BenQ specifies 2,500 ANSI lumens for the W770ST. This gives a comparable manufacturer rating for screening against other ANSI-rated models, but it is not a promise that the image will remain clear at any size or in any room light. Screen gain, ambient light, picture size, and lamp condition all influence the result. Check the actual lamp and the room's lighting plan rather than buying from a number alone. The published rating describes the model, not the brightness of a used projector today.
Plan the source and maintenance
The manual lists HDMI alongside PC, component, S-video, and composite inputs, plus a 10-watt mono speaker. That supports using a separate laptop or media source, but does not document an integrated app platform. Its 210-watt lamp also makes lamp hours and replacement planning part of ownership. Confirm which remote, cables, and source adapters are included with the exact unit. The historical listing's condition is not established by the BenQ manual, so inspect the projector before relying on its physical condition or remaining lamp life.
Choose distance or image detail first
The W770ST suits a room where shorter throw is more important than native Full HD. The HT3050 offers a 1920 × 1080 image and vertical lens shift, but its 1.15–1.5:1 throw range calls for more room between lens and screen. Neither choice is universally better; the screen, mount, source, and detail needs determine the fit. Treat this as a source-based comparison and check the exact model suffix, lamp, connections, and included accessories on a used offer.
What else to compare
Compare BenQ HT3050 when Full HD detail and vertical lens shift matter more than shorter projection distance.
Before you buy
Is the W770ST native 1080p?
No. BenQ specifies native 1280 × 720; support for a 1080p signal is not the same as a Full HD panel.
Is its lens ultra-short throw?
BenQ describes a short-throw lens with a 0.72–0.87:1 ratio; the saved sources do not classify it as UST.
Does the W770ST include streaming apps?
The manual documents external inputs, not a built-in streaming platform; use a compatible separate source.
