Our take
Vivitek identifies the D803W-3D as a 3D-capable DLP projector with native 1280 × 800 WXGA and 3600 ANSI lumens. The official specification gives a conventional 1.54–1.70:1 lens range, a 240 W UHP lamp, and several analog and digital inputs. It is a clear model match for a room that uses those features, although Vivitek's saved source does not assign one primary household or professional role.
A source-connected room that needs WXGA, stated ANSI brightness, legacy connectors, or the model's documented 3D input modes.
It is not a high-detail Full HD or 4K model, an integrated-app projector, a battery device, or a low-risk used purchase without checking lamp condition.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Vivitek explicitly lists native WXGA resolution and 3600 ANSI lumens.
- The manual 1.1× zoom and stated throw ratio make conventional distance planning possible.
- Dual HDMI plus VGA, component, S-Video, composite, and RS-232 expand legacy source and control options.
What to weigh up
- The 1280 × 800 image is below Full HD and can limit fine detail at larger screen sizes.
- Its 240 W UHP lamp has a finite life and the hours of a used unit remain unknown.
- The official page does not document battery operation or a built-in streaming operating system.

What the features mean for you
A verified legacy model with a flexible source panel
Vivitek's legacy page and datasheet identify the exact D803W-3D model and list two HDMI inputs, VGA, component, composite, S-Video, audio, and RS-232. The broad panel suits a room where older computers, AV equipment, or control systems remain in use. The page calls it a high-performance digital 3D projector but does not establish whether its primary audience is home cinema, school, or business, so the category role stays unassigned in matching data. Buyers should verify the chassis label and cable needs rather than infer intended use from the historical listing title alone.
WXGA and 3D define the image format
Vivitek lists native WXGA at 1280 × 800, with compatibility for a variety of video signals and specified 3D modes. That supports a widescreen computer image with more horizontal detail than SVGA while remaining short of Full HD. Compatibility with 1080p signals or 3D frame formats does not mean the projector has a 1080p native device. If image detail is important, compare screen size and viewing distance with the 1280-pixel native width. The model specification establishes supported modes, not the condition of any used DLP chip or optical path.
The ANSI rating is explicit
Vivitek lists brightness at 3600 ANSI lumens on its official product page and gives the lamp type as 240 W UHP. The ANSI label supports comparison with other products using that rating basis, while actual light from a used lamp depends on operating hours and mode. The datasheet lists a nominal standard-mode lamp life, but it cannot tell a buyer how much service remains in an individual unit. Ask for the hour counter and inspect the picture at the intended screen size. This is model-level source evidence, not a test or measurement of a present offer.
Conventional placement is measurable
The D803W-3D datasheet specifies a 1.54–1.70:1 throw ratio and 1.1× manual zoom and focus. That requires the projector to sit back from the screen and does not qualify as ultra-short throw. Use the ratio with the image width to choose a shelf or mount location. The page specifies vertical keystone but does not establish optical lens shift, so set the chassis square to the screen and avoid assuming that a digital correction can substitute for lens movement. Leave enough clearance for ventilation and future lamp access.
A lamp and external source are part of ownership
Vivitek's specifications identify an AC-powered UHP lamp, internal speaker, and inputs for outside video devices. The model's USB port is for service rather than a streaming app store, and the official page does not document integrated internet applications or battery use. Plan an external player, receiver, computer, or source switcher. On a used projector, inspect lamp hours, startup, image color, dust, fan noise, zoom, manual focus, remote, 3D synchronization, and all input ports. These steps help evaluate a particular unit but do not claim that one was tested or is currently available.
What else to compare
For documented native Full HD and short-throw education use, compare InFocus IN138HDST; for a presentation projector with 3000 ANSI lumens and native WXGA, compare InFocus IN2116.
Before you buy
What is the D803W-3D's native resolution?
Vivitek lists native WXGA at 1280 × 800; support for larger video inputs is not native resolution.
Does Vivitek give an ANSI lumen rating?
Yes. The official D803W-3D page specifies 3600 ANSI lumens for the model.
Can this projector sit close to a wall?
It uses a 1.54–1.70:1 conventional throw ratio, so it needs measurable screen distance rather than UST placement.

The decision
The D803W-3D is best for a known legacy source setup that benefits from its ANSI rating, WXGA DLP, 3D compatibility, and connector range.
