Our take
ViewSonic's PX800HD combines a native 1920 × 1080 image with 2,000 ANSI lumens and a 0.22:1 ultra-short-throw lens. Its listed 95–120-inch image range is designed for very close placement, about 0.12–0.25 metres from the wall depending on size. The fixed optical zoom means screen size is mainly a matter of cabinet and projector position, not a large zoom range. ViewSonic also lists two 10 W speakers and horizontal/vertical keystone adjustment. It fits a measured home theater where close placement is essential and the lamp, screen and external source plan are understood.
A fixed home-theater cabinet or console setup where a close-wall ultra-short-throw projector is required.
Avoid it if you need a portable battery projector, a large optical zoom range, built-in streaming apps, a screen outside the documented size range, or a lamp-free light source.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The native Full HD image and 2,000 ANSI rating are clearly specified by ViewSonic.
- A 0.22:1 throw supports 95–120-inch images from a short 0.12–0.25 m placement range.
- Two 10 W speakers, HDMI/MHL and keystone correction simplify a fixed home installation.
What to weigh up
- The lamp rating is 3,000 hours in normal mode and projector condition depends on remaining lamp life.
- Fixed zoom limits optical image-size adjustment after the cabinet position is chosen.
- The product page does not document built-in streaming apps, so an external source is needed for content.

Full review: how the features affect your choice
What the features mean for you
Choose Full HD and a measured UST screen size
ViewSonic specifies native 1920 × 1080 resolution for the PX800HD and a 95–120-inch image range. That Full HD format suits home-video sources, while the stated range gives a practical boundary for screen planning. Do not assume that a larger image will be supported just because another UST model offers it. Measure the screen width, cabinet depth and lens position against the manufacturer's chart. At an image size near the lower or upper end, the projected result and room light still matter, so inspect the exact unit and avoid treating the maximum as a brightness guarantee.
Use the ANSI value without extending its meaning
The PX800HD is rated at 2,000 ANSI lumens, which is an explicit measurement method and supports comparison against other ANSI-rated models. It remains an original model rating, not a measurement of the lamp in a used projector. ViewSonic lists a 3,000-hour normal lamp rating and a longer eco-mode figure; check the unit's lamp counter and picture before buying. A 120-inch image can require more light on the screen than a smaller one. Room lighting, wall color, screen gain and lamp condition all affect practical viewing, so size the image to the room rather than relying on one number.
Place it close to the wall with no zoom assumption
ViewSonic gives a 0.22:1 ultra-short-throw ratio and a placement distance around 0.12–0.25 metres for the stated image sizes. This lets the projector sit near a screen, which can reduce ceiling runs and the chance of a person crossing the beam. The optical zoom is fixed, so cabinet depth and projector position are part of the image-size adjustment. Make a physical mock-up before buying furniture or mounting a screen. Keystone can correct horizontal or vertical geometry, but it should be a final adjustment after the unit is centered and squared to the screen.
Build the home system around external sources
The official page documents HDMI, MHL, VGA, micro USB power and RS-232 connections, alongside two 10 W speakers. This is a conventional connected projector rather than a self-contained streaming television. Select a streaming player, game console or receiver that matches the available HDMI path and check any HDCP or resolution requirements. The built-in speakers can provide sound without extra equipment for casual viewing, while a larger theater may call for a receiver or soundbar. Confirm the connections and remote on a used unit; a model specification does not establish which accessories remain with a seller's package.
Inspect lamp history and the UST surface
The PX800HD uses a lamp rated at 3,000 hours in normal mode and up to 7,500 hours in eco mode. Ask for lamp hours and check startup, focus, color uniformity, fan and lens cleanliness. Because UST projection magnifies small surface irregularities, use a suitable flat screen or wall and ensure the projector cabinet is level. Verify that the screen begins at the correct height and that furniture will not block the light path. The lamp source is not laser-based, and the projector does not have battery operation. Those points make it a fixed home installation rather than a portable all-in-one.
Compare for your needs
A conventional-throw Full HD home projector can offer more freedom to place the chassis farther back and may provide a larger zoom range. The PX800HD is the specialized choice when the projector must sit very close to the wall.
