Our take
BenQ MH680 is a conventional-throw Full HD projector with stronger specification evidence than a generic mini model. BenQ's exact support materials and manual identify native 1920 × 1080, 3,000 ANSI lumens, 1.15–1.5:1 throw, 1.3× zoom, a lamp, and HDMI/USB connections. That combination gives a clear starting point for a video-presentation or multimedia room that can place the lens at the required distance. It is not a close-wall UST design, and the ANSI figure is a manufacturer rating rather than a measurement of an old lamp unit. Verify lamp hours, focus, ports, and accessory contents on the exact offer. This review makes no claim of personal image testing or current availability.
Full HD multimedia presentations where there is room for a standard projector distance and an external source.
It is not for a wall-adjacent cabinet, battery travel, native 4K imaging, or a maintenance-free laser installation.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- BenQ documents native Full HD 1920 × 1080 rather than only accepting a 1080p input.
- The 3,000 ANSI-lumen rating uses an explicit basis for comparison with other ANSI models.
- A 1.15–1.5:1 throw and 1.3× zoom provide measurable room placement flexibility.
What to weigh up
- The conventional throw needs distance and careful screen sizing; it is not UST.
- Lamp hours and the condition of a secondhand MH680 are not known from model documentation.
- Built-in streaming apps, battery operation, and optical lens shift are not established in the saved sources.

What the features mean for you
A native Full HD image for a conventional room
BenQ's model manual specifies a native 1920 × 1080 image for the MH680. That is Full HD rather than pixel-shifted or native 4K, and it is a useful resolution for current film, television, and multimedia sources. The model does not need to be described with vague “supports 1080p” wording: the cited source identifies native Full HD. Resolution alone does not determine image quality, however. Focus, screen size, source format, ambient light, and lamp condition all contribute. A room with a known screen and a workable lens distance gives this projector a better chance of fitting its intended job than an unmeasured wall.
Compare brightness only on an ANSI basis
BenQ lists 3,000 ANSI lumens for the MH680. Because the manufacturer uses the ANSI label, this is a meaningful value to compare with other explicitly ANSI-rated projectors. It is still a model rating, not a guarantee for a particular older lamp or a very large screen. Brightness falls in practical importance when the room is dark and the image is moderate, while ambient light can make even a nominally bright projector look washed out. Request a demonstration on the actual unit and ask for its lamp-hour reading. Keep the manufacturer number separate from projector listings that give peak, LED, or simply unqualified lumens.
Measure throw and use the zoom range
The MH680's documented throw ratio is 1.15–1.5:1 with a 1.3× zoom. This is conventional placement, not an ultra-short-throw lens; the projector needs a meaningful space between lens and screen. Measure screen width and lens-to-screen distance using BenQ's guide before selecting a table or mount. The zoom gives some flexibility around that position, but it cannot compensate for an unsuitable room. Physical centering and focus are preferable to heavy digital correction. Leave room for ventilation, power, HDMI routing, and maintenance access. Buyers should verify the precise screen size they intend to use against the manual rather than relying on a generic maximum-size claim.
Plan for an external source and lamp upkeep
BenQ's sources identify HDMI and USB connections along with the projector's other input functions. They do not establish a current built-in subscription streaming platform, so a streaming box, console, receiver, or computer may be a better source plan. USB connectivity should not be mistaken for proof of app streaming. The MH680 is a lamp projector, meaning usage hours and replacement history matter for a used device. Confirm the remote, input operation, lamp menu, power lead, picture geometry, color, fan, and any 3D accessories if those features are part of the intended system. The guide establishes original capabilities, not whether a specific seller's bundle contains every accessory.
Shortlist it for Full HD presentations, then inspect the used unit
The MH680 is a plausible multimedia presentation choice when Full HD resolution, an explicit ANSI rating, and the throw range meet the room plan. It is less suitable when the installation must be inches from the wall, the projector must run on a battery, or the buyer wants a laser light source with less lamp maintenance. Ask to see the exact unit start from cold, focus the whole image, display a clean white and dark test, and accept the intended source. Check for lamp warnings, dust, fan noise, damaged HDMI/USB sockets, and accessories. These are inspection questions, not claims that a particular MH680 has passed them. The review relies on BenQ model material and makes no statement about current stock, sale price, or buyer opinions.
What else to compare
For short-distance Full HD placement, Acer H7550STz has a documented short-throw ratio but no asserted ANSI value for its exact variant. For a battery-powered small image, ASUS P3B trades resolution and output for portability.
Before you buy
Is BenQ MH680 native Full HD?
Yes. BenQ's manual documents a native 1920 × 1080 image for the MH680.
What brightness basis does BenQ specify?
BenQ lists 3,000 ANSI lumens, which remains a manufacturer rating and may not describe an older lamp's present output.
Can the MH680 sit right beside the wall?
No. The model's 1.15–1.5:1 throw is conventional projection and needs measured lens-to-screen distance.
