Our take
BenQ’s MP721c is an older compact XGA DLP projector for a presentation system that still uses VGA, DVI-A, component, S-Video, or composite inputs. The manufacturer-hosted manual is shared by MP721 and MP721c and confirms common 1024 × 768 resolution, a 200 W lamp, a 5.9-pound body, and a 2 W mono speaker. It does not establish an MP721c-specific ANSI output figure, so brightness remains unknown rather than borrowed from a sibling listing. Check the exact suffix, connectors, lamp status, and source adapters before considering an individual unit.

Skip it if you require HDMI without adapters, Full HD detail, an ANSI-lumen threshold, built-in streaming, battery power, or interactive classroom pens.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The 5.9 pound chassis is manageable for occasional movement between nearby meeting rooms.
- BenQ documents XGA DLP imaging and computer, DVI-A, S-Video, composite, and component inputs.
- Manual zoom and a built-in mono speaker support a basic legacy presentation arrangement.
What to weigh up
- The shared manual does not establish an MP721c-specific ANSI brightness figure.
- The manual lists no HDMI input, so modern sources may need signal-compatible adapters.
- A 200 W lamp, 2 W speaker, and older model age make maintenance and availability checks important.

Full review: how the features affect your choice
What the features mean for you
Is XGA enough for the material you present?
BenQ’s MP721/MP721c manual lists a 1024 × 768 XGA image on a single-chip DLP system. That 4:3 format can suit older slides and documents designed around XGA-era laptops, but it has fewer pixels than WXGA and native Full HD. A higher-resolution computer signal is resized to the projector’s native grid, so it does not increase the physical detail. This makes the MP721c most reasonable when it is replacing a compatible legacy unit or serving simple text and graphics. If the room now displays dense spreadsheets, software interfaces, or wide video, compare the required pixel detail before committing to an older XGA design.
What connections can the manual confirm?
The shared BenQ manual lists a D-sub 15-pin RGB input, DVI-I used with an analog DVI-A signal, S-Video, composite RCA, and component video through the RGB connection. It also lists a stereo mini-jack audio input and a 2 W mixed-mono speaker. There is no HDMI input in the specification table, so a current laptop, disc player, or streaming device may need a compatible converter. Conversion can introduce resolution, copy-protection, or handshake limits, so test the actual source chain rather than assuming a passive adapter will work. Verify the unit’s ports and supplied cables because this is an old projector family.
Why is ANSI brightness left unknown?
The MP721/MP721c manual provides common model-family specifications such as resolution, lamp power, dimensions, and inputs, but it does not establish a model-specific ANSI-lumen figure for the MP721c. The product packet specifically calls for separating the c suffix from MP721 facts. To avoid assigning a sibling’s output claim to this projector, the matcher leaves ANSI brightness unknown. A manual lamp and age also mean that the output of an individual used unit depends on its hours and condition. Ask for the exact model label, lamp-hours display, and a clear image demonstration if the projector’s visibility is central to the purchase.
Can the lens fit your screen distance?
BenQ describes a manual zoom lens and includes a projection-distance chart for 4:3 image sizes. The chart shows a conventional throw distance rather than a close-wall ultra-short-throw arrangement. Use the screen diagonal and chart together when planning a shelf; digital keystone correction can help with modest setup error but changes image geometry and does not move the lens. The manual lists a 5.9-pound weight, which is practical for careful room-to-room carrying but not a battery-powered presentation experience. The 200 W lamp and ventilation needs also mean the projector should have a clear, stable location with room to cool after use.
Who should keep this legacy model on a shortlist?
Choose the MP721c only when its XGA format and analog connections solve a specific existing-room problem and the individual unit can be checked. The InFocus IN2104 is another XGA business model with a manufacturer sheet that specifies dual VGA-style computer inputs, USB, RS-232, and 2500 lumens without an ANSI label. The ViewSonic PJD6352 adds dual HDMI, a 10 W speaker, and a stated 3,500 ANSI lumens if the room can use conventional placement. These alternatives show why exact connector and brightness evidence matter. The MP721c’s identity and shared family facts are documented, but the suffix-specific ANSI output remains unresolved.
Compare for your needs
The ViewSonic PJD6352 offers dual HDMI and an explicit 3,500 ANSI-lumen specification; the InFocus IN2104 is another XGA legacy-input choice.

Before you buy
Does the MP721c have an ANSI brightness rating in its manual?
The shared MP721/MP721c manual does not establish an MP721c-specific ANSI output figure, so it remains unknown.
Does this model include HDMI?
The manufacturer manual lists VGA, DVI-I in analog mode, S-Video, composite, and component through an adapter, not HDMI.
Is it native Full HD?
No. BenQ specifies a native 1024 × 768 XGA image for the MP721/MP721c family.

The decision
The MP721c belongs on a shortlist only when legacy inputs and exact model matching matter. Keep its ANSI brightness unknown and check lamp condition.
