Our take
The TX700 is a legacy presentation projector with native XGA resolution, an explicitly ANSI-labeled 2,200-lumen rating, and a conventional 1.93–2.13:1 lens range with 1.2× manual zoom. Optoma's data sheet lists a UHP lamp and several older wired inputs. This combination can suit a business or school room that already uses XGA slides and compatible sources. It is not a portable battery device or an ultra-short-throw model, and a used unit's lamp hours and connector condition must be assessed separately from the original specifications.
Business or school presentations from compatible wired sources in a room with conventional projector distance.
It is not a fit for Full HD or 4K detail, battery operation, a wall-adjacent lens, streaming apps, or a room without enough throw distance.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The manufacturer sheet states native 1024 × 768 XGA resolution and a 4:3 format.
- Optoma specifies 2,200 ANSI lumens, preserving a clear output basis for comparisons.
- A 1.2× manual zoom and multiple analog/digital inputs support some existing classroom and office systems.
What to weigh up
- Native XGA has less widescreen detail than WXGA or Full HD.
- The 1.93–2.13:1 lens needs conventional room depth and has no documented UST placement.
- Its UHP lamp and older source connectors require maintenance and compatibility checks.

What the features mean for you
Match native XGA to presentation content
Optoma identifies the TX700's native format as 1024 × 768 XGA, a 4:3 image commonly associated with older presentation equipment. That can fit existing slides, documents, and classroom materials designed for the format. It offers less horizontal detail than WXGA or Full HD for widescreen video, dense spreadsheets, or small computer text. A different input resolution will be processed for the native image rather than changing it. When replacing a projector, check the computer's output and the screen's aspect ratio so the selected model fits the content instead of relying on a generic compatibility list.
Use ANSI lumens as a stated comparison point
Optoma rates the TX700 at 2,200 ANSI lumens. The ANSI label gives a more specific basis than an unqualified lumen total and can help compare documented business models. It does not guarantee readability under all office lights or at every screen size. Ambient light, lamp mode, screen surface, image size, and lamp age affect the actual picture, especially for an older projector. Request the lamp-hour record and inspect the image from the specific unit. The original rating describes the manufacturer's specification, not a current measurement of a used example.
Calculate a conventional lens position
The TX700 data sheet lists a 1.93–2.13:1 throw ratio and 1.2× manual zoom. The ratio requires conventional space from projector to screen; it is not intended for a position immediately beside the wall. The zoom provides a limited range for fitting the image after the distance is established, so measure image width and lens position before choosing a ceiling mount or table. Allow room for cables and ventilation. If the physical room cannot provide this depth, look for a model with a documented short-throw or UST lens rather than expecting the zoom to solve the geometry.
Check the source panel against the devices you own
Optoma's data sheet lists DVI-D, VGA, S-video, composite, and a component-video adapter connection. These inputs may suit older office computers, DVD players, and classroom equipment, but current laptops and streaming players often rely on HDMI or USB-C. Determine what the actual source outputs and whether a suitable adapter supports the needed signal before installing the TX700. The specification sheet does not document built-in streaming apps, so content comes from external hardware. A converter can add cost and complexity, and does not create a different native resolution.
Include UHP lamp service in the ownership plan
The TX700 uses a 200 W UHP lamp and an integrated 2 W mono speaker according to the manufacturer data sheet. A lamp projector needs mains power and eventual maintenance; brightness and color on an older lamp can differ from the original rated state. Confirm the lamp hours, service history, lamp availability, remote, and source connections on a specific used unit. The speaker can support a simple presentation, but a larger audience may require external sound. None of these original model specifications establishes the present condition or remaining life of an individual projector.
Choose it for an existing room, not a mobile role
The TX700 is most relevant where XGA content, a conventional mounting distance, and wired presentation equipment already define the room. Its ANSI rating is clearly stated, but its 4:3 resolution, lamp, and connector set make it a poor replacement for a battery projector or a current Full HD home system. Confirm the physical throw, screen ratio, and signal path first, then inspect image focus and lamp hours on the specific device. This recommendation follows Optoma's historical data sheet and is not a hands-on test or a report about any active offer.
What else to compare
For a short-throw presentation room, compare the Vivitek D855ST's fixed 0.66:1 lens and XGA format; for a native Full HD home image, compare the Optoma HD28HDR and preserve its unqualified lumen wording.
Before you buy
What is the TX700's native resolution?
Optoma's data sheet lists native 1024 × 768 XGA resolution.
Are 2,200 lumens ANSI?
Yes. The TX700 manufacturer data sheet labels the rating as 2,200 ANSI lumens.
Can it sit close to the screen wall?
It uses a 1.93–2.13:1 conventional throw range, so it needs room depth rather than UST placement.

The decision
The TX700 is a measured-room presentation option when XGA and legacy wired sources fit the job. Its explicit ANSI rating is useful, while throw distance and lamp condition remain practical checks.
