Our take
The MX766 is a source-flexible XGA projector for an older office or classroom, with a 1.5× zoom lens, HDMI and legacy video inputs, USB presentation functions, and a 20 W speaker system. Its exact-model brightness remains unestablished in the reviewed source packet, so it should not be ranked by output. Choose it only when the 4:3 format and available connections match the room and the used lamp can be checked.
A legacy office or classroom room with XGA slides, mixed analog and HDMI sources, and a working lamp whose condition can be checked.
It is not a native Full HD or 4K home-cinema projector, a portable battery device, or a brightness-ranked recommendation; choose a newer panel when resolution is central.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- BenQ specifies native XGA 1024 × 768 DLP imaging for the MX766.
- HDMI, VGA, composite, S-Video, and USB reader/display functions cover several meeting-room source types.
- The 1.5× zoom lens and 20 W audio system can reduce setup friction in a compatible room.
What to weigh up
- No exact MX766 brightness figure was included in the reviewed source set, so it must remain unknown.
- Native XGA 4:3 has less detail and a different shape than modern Full HD widescreen video.
- A 310 W lamp makes actual hours, output, ventilation, and replacement parts important on a used projector.

What the features mean for you
Does its XGA format suit your material?
The MX766 uses a one-chip DLP system with native 1024 × 768 XGA pixels in a 4:3 image. That format can suit legacy slides and computer presentations made for older square screens, but it provides less detail than WXGA or Full HD. Text may remain readable at a modest size while losing clarity on a very large image. A projector's ability to accept a higher signal does not make its panel higher resolution. Check the source laptop and slide deck before selecting it. If the room shows widescreen video or dense data, compare a current 16:9 or 16:10 model instead of relying on scaling.
Why is brightness left unknown?
The saved MX766 packet supports its identity, native format, lens, connectors, speaker, and lamp, but it does not establish an exact-model brightness number. Related BenQ models can have different ratings; copying a figure from the MX767 or MX822ST would create a false comparison. Leave the value blank until the exact MX766 datasheet supports it. This makes a used-unit inspection especially important: ask about lamp hours, view the image in the actual room, and check for dim areas, color differences, or blinking. Model identity alone does not show current output. Buyers who must compare brightness numerically should choose a projector whose manufacturer provides an exact-model standardized rating.
Can the lens and connections work in your room?
BenQ documents a 1.5× zoom lens and HDMI, VGA, composite, and S-Video inputs. The zoom provides a range for framing after the projector is mounted, while the mix of connections can help a room retain older computers or video sources. It does not make this an ultra-short-throw projector; measure the screen and installation distance against the manual before selecting a shelf or mount. A digital-to-analog converter may be needed for some newer sources, and its conversion capability should be checked separately from the projector's ports. USB reader/display features support certain local content, but they are not a network streaming platform.
What does the onboard audio and lamp mean?
The manual describes a 20 W stereo speaker system and a 310 W lamp. Onboard audio may cover small rooms or basic playback, though a larger class or meeting space may need external sound. The lamp is a service item; a published replacement rating would describe its design life, not how much remains in a used example. Ask for the installed lamp's hours and check whether the fan, focus, and zoom controls work. Provide clearance for ventilation and a safe route for power and source cables. Older projectors can also depend on remote controls and adapters that sellers may not include, so confirm every accessory required for your use.
Who should consider an MX766?
This model belongs on a shortlist when a meeting room already uses 4:3 content, needs a particular analog input, or benefits from its USB presentation functions. The 1.5× zoom and integrated speaker are concrete advantages, but the missing brightness fact means it is not a safe choice for a bright room based on model data alone. The unit is older and lamp-based, so condition, hours, dust, and replacement availability should guide the decision. Compare BenQ MX525 for another XGA model with different connectors and a smaller speaker, or choose a new WXGA/Full HD projector when text detail and modern video sources matter more.
What else to compare
Compare BenQ MX525 for another XGA business projector, or a newer WXGA/Full HD model when more image detail and a standardized output rating are required.
Before you buy
What is the MX766's native resolution?
BenQ specifies native XGA 1024 × 768 imaging for the MX766.
Can I use a brightness figure from the MX767?
No. The reviewed facts do not verify the MX766's brightness from its exact-model source.
Does it connect to an HDMI laptop?
Yes. BenQ's model manual lists HDMI as well as VGA and several legacy video inputs.
Does the USB reader provide streaming apps?
No. The manual describes USB media functions, not an integrated streaming-app platform.

The decision
Choose the MX766 only when its exact XGA and input features match the room and the unknown brightness is acceptable after a direct unit check.
