Our take
The NEC VT47 is a legacy presentation projector with a documented native 800 × 600 SVGA panel and 1,500 ANSI lumens. Sharp/NEC's installation guide also describes a fixed lens, manual focus and digital zoom, approximately 1.2:1 throw, a 130 W lamp, a 1 W mono speaker, and VGA/component, S-Video, composite, and serial connections. These facts make it a specific fit for an existing classroom, meeting room, or slide setup that still uses compatible analog equipment. It is not a current all-purpose theater pick: the resolution is low by modern standards, HDMI is not documented in the cited input list, and the lamp condition of any individual unit is unknown.
A legacy slide or presentation setup that already depends on compatible analog sources and accepts SVGA detail..
It is not for native HD or Full HD viewing, an HDMI-only source chain, battery use, or a room that needs a modern built-in media platform. Confirm the analog adapters your source requires.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Sharp/NEC gives an explicit 1,500 ANSI-lumen figure for the VT47.
- Manual focus and a stated throw make basic analog-room placement measurable.
- VGA, component, composite, S-Video, and serial connections may match retained AV equipment.
What to weigh up
- The native 800 × 600 image has substantially fewer pixels than WXGA or Full HD.
- The saved installation guide does not document an HDMI input.
- A 130 W lamp makes hours and replacement history relevant on a used example.

Full review: how the features affect your choice
What the features mean for you
Treat SVGA as a narrow compatibility choice
Sharp/NEC's model-family documentation identifies a native 800 × 600 panel. The VT47 can accept other signal formats, including higher-resolution input modes, but scaling those inputs does not add native pixels. That difference matters for spreadsheet text, detailed diagrams, and widescreen video. It may be adequate for large, uncomplicated slides in a room whose source and screen already work around the projector, but a buyer starting a new system should compare WXGA or Full HD models such as Epson EB-U32 or BenQ HT4050. The choice depends on the existing content and connections rather than a generic ranking.
The ANSI rating is documented, but not a guarantee for a used lamp
The VT47 installation guide lists 1,500 ANSI lumens, which allows a like-method comparison with other explicitly ANSI-rated models. It does not describe the present output of a decades-old unit. Lamp hours, lamp mode, dust, optical condition, and maintenance can change a particular projector's result. Request the lamp timer and service history and inspect the exact unit before deciding whether it meets a room-brightness requirement. Keep the model's published ANSI figure distinct from Acer H7550ST's untyped lumen statement or Epson's separate color/white methods.
Check the analog source chain before buying
Sharp/NEC documents VGA, component, S-Video, composite video, and serial control connections. The input list does not establish HDMI, so a laptop, streamer, or modern player may need an adapter or a different projector. Confirm which conversion path preserves the intended picture and audio, and check that any receiver or switcher supports the necessary analog connection. A one-watt mono speaker is a basic onboard output, not a home-theater sound solution. This is where the VT47 can still make sense: the room already has compatible legacy equipment and the buyer values a directly documented ANSI rating.
Manual focus and digital zoom do not replace lens movement
The installation guide lists a fixed lens with manual focus and digital zoom and gives an approximate 1.2:1 projection ratio. Measure the lens-to-screen distance and image width before mounting the projector. Digital zoom changes framing electronically; it is not optical lens shift and does not support arbitrary side-to-side repositioning. The saved material does not establish a lens-shift mechanism. Place the projector square to the image and keep enough adjustment room for focus. For a new room that needs flexible positioning, a model with verified optical shift or a much shorter throw may be easier to accommodate.
Reuse makes more sense than a fresh home-theater build
The VT47's documented combination of SVGA, analog ports, lamp power, and a simple mono speaker is most relevant when replacing a compatible unit or keeping an older presentation room working. It is not a battery projector and the sources do not document a streaming system. Compare it with NEC NP-L102W if you want a newer compact installation style, or with Epson PowerLite 2155W for WXGA and wireless meeting functions, while verifying the used item's exact condition. This review describes the model facts and practical compatibility trade-offs; it does not claim a personal test of brightness or image quality.
Compare for your needs
Epson PowerLite 2155W is a newer WXGA meeting-room direction with wireless networking and standardized color/white output. Epson EB-U32 adds WUXGA detail and HDMI for a broader modern presentation chain.

Before you buy
What is the VT47's native resolution?
Sharp/NEC's documentation identifies native 800 × 600 SVGA; higher input compatibility does not make it native HD.
Is its 1,500-lumen figure ANSI-rated?
Yes. The VT47 installation guide labels the 1,500-lumen rating as ANSI, though a used lamp may produce a different result.
Does the cited guide show HDMI?
No. The reviewed input list names VGA, component, S-Video, composite, and serial control, but does not document HDMI.

The decision
Choose the VT47 only when its analog connections, modest SVGA image, and documented ANSI rating match an existing setup. Check lamp hours and the precise source adapters before treating it as ready to reuse.
