Our take
Optoma's GT700 GameTime is a short-throw home projector whose defining tradeoff is room distance against native image detail. Its 0.72:1 ratio can make a large picture from less depth than a conventional projector, while the native WXGA panel is below Full HD. The datasheet gives an ANSI-labeled brightness rating and two 5 W speakers, but does not establish gaming latency or the condition of a used lamp. Check source timing and the exact unit before purchase.
A home or game-room setup with limited throw distance, an external HDMI source, and content that suits native WXGA.
It is not a fit for native Full HD or 4K, confirmed low-latency gaming, built-in streaming, a battery-powered setup, or ultra-short-throw placement measured in only a few inches from the wall.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- A 0.72:1 throw allows a shorter lens-to-screen distance than standard-throw home projectors.
- Optoma lists native WXGA and 2,300 ANSI lumens for the exact GT700 model.
- HDMI, older analog inputs, and dual 5 W speakers simplify some small-room setups.
What to weigh up
- WXGA has less detail than Full HD for fine game interfaces and widescreen film.
- The saved datasheet does not provide an input-lag or gaming-response measurement.
- Compatible 3D glasses are required separately, and the lamp condition is unit-specific.

Full review: how the features affect your choice
What the features mean for you
What does its short throw change?
Optoma specifies a 0.72:1 short-throw ratio and an image range from about 34 to 300 inches. That can reduce the distance required behind a low table or seating row, making it easier to keep the presenter or players out of the beam. It is still a short-throw projector, not an ultra-short-throw unit designed to sit almost against the wall. Measure the lens position and image width carefully; a small distance error changes picture size noticeably. Leave room for ventilation and cable access, and do not substitute digital keystone for a measured placement.
Is WXGA enough for gaming and video?
The GT700's native resolution is WXGA 1280 × 800 with a 16:10 shape. This gives more horizontal detail than XGA but less than native Full HD, so fine menus and small interface text may look softer on a large screen. A console or streaming box can send compatible signals, but accepting a higher-resolution signal does not make the displayed panel 1080p. Consider the screen size and seating distance before treating the model name GameTime as evidence of a modern gaming mode. Optoma's saved sheet does not provide a response-time value.
How should 2,300 ANSI lumens guide the room?
Optoma labels the GT700's 2,300-lumen figure ANSI, so it can be compared on that stated basis with other ANSI-rated models. That number does not guarantee the same image in every room: ambient light, lamp mode, screen surface, and image size affect perceived brightness. A small, dim room may work better than a large sunlit wall. The original specification also cannot tell you what a used lamp currently produces. Ask for the unit's lamp hours and request a test image at the intended size before relying on the rating.
Which sources and sound can it use?
The datasheet lists HDMI, VGA, S-video, and composite connections, plus two 5 W speakers. HDMI can connect a console or external media source, while legacy inputs may help with older equipment. Neither HDMI nor an analog socket means apps are built into the projector; plan the source device separately. The paired speakers can keep a simple room self-contained, although they are not equivalent to a larger external sound system. Check the used unit's actual ports and test audio with the source before mounting, since a model brochure cannot diagnose worn connectors.
What is required for 3D and lamp upkeep?
Optoma lists 3D modes that require compatible source equipment and glasses sold separately. The source timing and eyewear must match before expecting a 3D picture; the listing title does not prove that a used offer includes glasses. The projector is lamp-based, so verify lamp hours, replacement history, filter condition, fan noise, focus, color uniformity, and image stability. Its original model sheet cannot establish today's lamp output or remaining life. These are important checks for a used home projector that may have spent years in a warm room or ceiling mount.
Who should shortlist the GT700?
The GT700 can suit a game room where conventional projector depth is unavailable and native WXGA is acceptable. It is less persuasive when the priority is Full HD text detail, current high-refresh gaming, or app convenience. Compare its short throw with the table and screen arrangement rather than relying on the GameTime branding. If a source has strict resolution or latency requirements, confirm those against the exact timing chart; no low-lag figure is established in this saved packet. The recommendation follows Optoma's model documentation and makes no hands-on or current-availability claim.

Before you buy
Is the GT700 a native Full HD projector?
No. Optoma specifies native WXGA at 1280 × 800 for the GT700.
How close can it sit to the screen?
Its documented 0.72:1 ratio is short throw; use the model distance chart for the exact image size.
Does its GameTime name confirm low input lag?
No. The saved model datasheet does not give an input-lag or response-time measurement.

The decision
The GT700's practical advantage is reduced throw distance, not modern gaming performance. Its WXGA panel, lamp, and unverified latency should fit the buyer's priorities.
