Our take
The BenQ MX720 is an older wired presentation projector whose strongest confirmed features are native XGA resolution, HDMI, RJ-45 control and a 10 W speaker. BenQ's manual lists a 240 W lamp and a weight of about 2.9 kg. The reviewed exact-model materials do not establish an ANSI-lumen rating or a throw ratio that can be used to match brightness or room distance, so both stay unresolved. It may suit a room whose slides and cabling are already built around XGA and physical connections, but current lamp condition, placement and image quality must be checked on the particular unit.
A wired business room that already uses XGA material and can verify the exact lamp, throw distance and present image condition..
It is not an app-based projector, a high-detail widescreen home-cinema display or a cordless travel model. Buyers should avoid treating a historical listing's lumen number as ANSI without an exact manufacturer rating.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- BenQ's exact model manual identifies native XGA 1024 × 768 and an HDMI input.
- RJ-45 control can suit an installed meeting room with a wired management system.
- A 10 W speaker and 2.9 kg chassis cover basic presentation use without suggesting portability on battery.
What to weigh up
- The reviewed manual does not supply a verified ANSI output number or an exact throw ratio.
- Its 4:3 XGA image offers less widescreen detail than WXGA or Full HD panels.
- A 240 W lamp is a consumable and its remaining service life depends on the individual unit.

Full review: how the features affect your choice
What the features mean for you
XGA supports a legacy slide workflow
BenQ specifies native XGA at 1024 × 768 on the MX720. That 4:3 format may fit presentations and rooms designed around older computer output, but it contains fewer horizontal pixels than WXGA and Full HD. A widescreen video source can be displayed, yet the image must adapt to the panel's shape and detail. Check the computer's output settings and any resolution requirements in the room before choosing this model. The fact that HDMI is present makes modern sources easier to connect, but it does not change the projector's native pixel grid. For dense spreadsheets or fine text, compare a higher-resolution projector and inspect a real sample at the intended seating distance.
Leave brightness unscored without ANSI evidence
The BenQ manual reviewed for this packet identifies the lamp and input hardware but does not establish a manufacturer ANSI-lumen rating. A number copied from an older title or reseller cannot be substituted for a method-labeled figure. This means the MX720 cannot be confidently matched to a brightness threshold from the saved sources. A buyer who wants it for an illuminated classroom should request an exact model specification and inspect its present output in the intended mode. Lamp age, image size and room light matter independently. The absence of an ANSI claim is not proof that the projector is dim; it is a limit on what can be compared responsibly.
Verify lens distance before installation
The saved exact-model manual confirms an optical projector but the packet does not establish a trustworthy throw ratio for this article. Do not use the chassis size or a generic projector calculator to promise a screen width from an assumed distance. Request the MX720 projection table or calculate from a manufacturer source that names the exact model. Lens shift is also not established in the checked documentation, so plan to place the projector square and at the correct height rather than relying on an optical adjustment. If the room has fixed seating or a ceiling mount, resolving placement first may determine whether this model is viable at all.
HDMI and RJ-45 make a practical wired room
BenQ's manual identifies HDMI and RJ-45 control, providing one modern video path and a wired management connection. The 10 W speaker can help with basic spoken audio, though it may not fill a larger room or support movie sound. The source set does not document integrated streaming apps or battery operation. Plan on an external source device and verify that its video output is compatible with the projector. Check the actual HDMI input, control behavior, remote, audio path and cables; model specifications do not guarantee that each port on a used projector still works. These connections make the MX720 more suited to an installed presentation system than to mobile viewing.
A lamp-hour check belongs in any used purchase
The MX720 uses a 240 W lamp. Its original lamp-life estimate is a model specification, not the remaining life of an individual unit. Ask for the on-screen hour count and replacement history, then view a uniform image for dim patches, discoloration, dust shadows and focus problems. Test the HDMI signal, RJ-45 control, speaker, zoom/focus, remote, fan and power cycle. The 2.9 kg weight is manageable for occasional movement, but BenQ does not describe internal battery use. Confirm that the label says MX720 rather than MW721 or another close suffix, and check the package before ordering an adapter or mount. No hands-on condition judgment is made here.
Compare for your needs
For an ANSI-rated presentation choice, compare Optoma TW615-3D if WXGA and conventional throw suit the room. Epson PowerLite 4650 offers a higher-detail profile with lens shift but keeps its output figures in Epson's color/white measurement terms.

Before you buy
What is the MX720's native resolution?
BenQ's exact manual identifies native XGA 1024 × 768.
Is its brightness ANSI-rated?
The reviewed exact-model manual does not establish an ANSI-lumen figure, so the profile leaves that comparison value unknown.
Can I calculate the screen distance from the saved specifications?
Not from this packet. Obtain the MX720's exact projection table before fixing the mount or screen size.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.

The decision
The MX720 is a possible legacy-room reuse when XGA, HDMI and network control fit, provided its unverified brightness, throw and lamp condition are checked first.
