Our take
The BenQ MH733 is a business projector for rooms where Full HD detail, bright presentation output, and a conventional zoom lens matter more than portability. BenQ specifies native 1920 × 1080 DLP, 4,000 ANSI lumens, a 1.15–1.5:1 throw ratio, and 1.3× zoom. Those figures support a useful room-planning comparison, but do not describe the remaining life or condition of an individual used lamp. Treat the model search as an exact-model discovery route and verify the offered unit's inputs, lamp hours, and remote before relying on it.
A meeting or training room with a measured throw distance and HDMI or computer sources.
It is not for battery-powered use, close-wall UST placement, or a self-contained streaming setup; measure the installation distance first.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- BenQ identifies a native 1920 × 1080 panel and labels the 4,000-lumen rating ANSI.
- The 1.15–1.5:1 throw range and 1.3× zoom give a defined placement window.
- Its business designation and source set suit meetings that use external computers or media players.
What to weigh up
- A conventional lens needs real room depth and will not fit every shallow cabinet.
- The lamp's remaining life and the condition of any second-hand unit are unknown.
- The reviewed sources do not document a built-in battery or streaming-app operating system.

What the features mean for you
Native Full HD is different from accepting a signal
BenQ specifies native 1920 × 1080 DLP imaging for the MH733. That is a sensible baseline for widescreen video, detailed slides, and computer dashboards in a meeting room. Signal compatibility and image processing should not be confused with the number of pixels in the panel: the native specification is the relevant figure when comparing fine detail. Think about how far viewers sit from the screen and whether spreadsheet labels remain legible at the intended image size. A higher input signal cannot add physical pixels to a 1080p imager.
The ANSI label gives the brightness claim a basis
The official specification labels the output at 4,000 ANSI lumens, so this review keeps that unit intact instead of treating an unqualified lumen number as equivalent. It is a substantial model-level rating for a business projector, but it does not promise the same output from a lamp that has been used for years. Ask for the on-screen lamp-hour count and inspect a uniform field for discoloration or unevenness. Room light, screen material, picture mode, and image size still affect what an audience sees. The source does not measure any particular offer.
Calculate the conventional lens position
BenQ lists a 1.15–1.5:1 throw ratio and 1.3× zoom. Use the screen width and that ratio to check whether the planned lens position lands within the optical range, then leave room for the projector body, ventilation, and cable bend. Zoom offers adjustment after a mount location is chosen; it does not turn the MH733 into an ultra-short-throw design. The saved specification does not establish optical lens shift, so plan image height and offset from the lens placement guidance. Keystone correction is not a substitute for a mount that is square to the screen.
Use a separate source and audio plan
BenQ positions the MH733 for business projection and documents wired source connections. That is a different workflow from a projector with an integrated TV operating system: connect the meeting computer, a room system, or a separate media player and choose the appropriate input. The reviewed model specifications do not document consumer streaming apps. If a video conference or online service is needed, confirm which connected device will provide it and whether the room's audio setup meets the audience's needs. Do not assume that an HDMI input, network management feature, or wireless presentation function is the same as an app platform.
Check the installed unit, not only the model rating
The MH733 is a lamp-based model, which makes service history relevant whenever the exact listing is used or refurbished. Confirm the label says MH733, review its lamp-hour menu, and check focus from center to corners. Test each input planned for the room and verify the remote and power cable are present. The original datasheet gives model specifications, not the accessories in a current package. No price, stock level, sales ranking, owner-review consensus, or hands-on result is assumed here. Choose this model if the documented optical range and input workflow suit a known room.
What else to compare
For a native XGA room with a higher throw ratio, compare InFocus Work Big IN32. For a compact battery model, compare AAXA M6.
Before you buy
Is the MH733 native 4K?
No. BenQ specifies a native 1920 × 1080 DLP image for the MH733, so it is a Full HD model.
Are the 4,000 lumens ANSI?
Yes. BenQ labels the MH733's 4,000-lumen output as ANSI in its official specification.
Can it sit right beside the screen?
No UST placement is documented; its 1.15–1.5:1 conventional throw needs a measured projection distance.
