THE SHORT ANSWER

Our take

Optoma's EH345 data sheet describes a single-chip DLP projector with native Full HD 1920 × 1080. The listed brightness is 3200 lumens, but the sheet does not label it ANSI. It also specifies a 1.13–1.47:1 throw, 1.3× optical zoom, manual focus, vertical keystone, lamp modes, and a 10 W speaker. This makes the projector straightforward to plan around for wired video or presentation sources if the room has conventional throw distance. The spec sheet cannot establish the condition of a renewed or used unit.

Consider it for

A meeting or home room with space for conventional projection, an HDMI source, and a need for native Full HD rather than a smart operating system..

Look elsewhere if

It is not for native 4K, ultra-short-throw placement, built-in app streaming, or an ANSI-only brightness cutoff based on this data sheet.

Pros & cons

What could work for you, and what to consider before buying.

What works in its favor

  • Optoma specifies native 1920 × 1080 Full HD rather than only a high-resolution input mode.
  • The 1.13–1.47:1 throw and 1.3× optical zoom support concrete placement calculations.
  • HDMI and a 10 W speaker support a simple wired source setup.

What to weigh up

  • The listed 3200 lumens are not labeled ANSI in the checked data sheet.
  • A 1.13:1 minimum throw still needs meaningful distance from the screen.
  • The sheet cannot reveal the lamp age or condition of a particular renewed projector.

Full review: how the features affect your choice

What the features mean for you

How much detail does the EH345 resolve?

Optoma specifies a native Full HD 1920 × 1080 DLP imager. That supports widescreen film and presentation detail beyond XGA or WXGA, while remaining below native 4K. Higher incoming formats are scaled rather than added to the chip's pixel grid. Use the native resolution to match a laptop, console, or Blu-ray source and decide how large the image can be before fine detail is lost at the seating distance. Check focus at screen edges after placement rather than assuming the specification guarantees a uniform used unit.

How should the 3200-lumen figure be interpreted?

Optoma lists 3200 lumens, but the checked sheet does not call the figure ANSI. Preserve the source wording and avoid comparing it numerically with ANSI-labeled models as if the methods matched. Room light, screen size, mode, and lamp condition all matter. The sheet lists lamp-life modes, but that does not reveal remaining hours in a particular projector. Ask for the on-screen lamp counter and inspect an image at the intended size. If a procurement threshold requires ANSI, select a model whose source uses that label.

Will the lens fit the room?

The EH345's throw ratio is 1.13–1.47:1 and its optical zoom is 1.3×. Multiply screen width by the desired throw ratio to estimate lens distance, then confirm the exact image size in Optoma's chart. Vertical keystone can correct some tilt, but it is not optical lens shift. This is conventional projection, not a close-wall UST setup. Measure the mount, allow air space around the lamp housing, and route HDMI before fixing the projector position.

What does the wired panel support?

Optoma lists HDMI, USB, VGA in/out, RS-232C, video, audio in/out, and a 10 W speaker. That accommodates common computers and external video devices, while an additional player can provide streaming apps. The data sheet does not document a built-in smart platform. Confirm the required ports are present and working on the exact unit, especially when considering a renewed listing. Check the audio path and source resolution as well as picture output; adapters and cable length can affect setup.

What should be inspected on a renewed projector?

Optoma's sheet identifies lamp modes and a replaceable lamp but cannot tell whether a particular renewed projector has a fresh or aged lamp. Ask for the counter and verify startup, cooling, focus, zoom, keystone, remote response, fan noise, and each input. Look for color uniformity and dust spots with a neutral image. The title of a renewed offer is not a condition report, and this profile does not infer a current ASIN or stock status from the historical row. This review is based on Optoma documentation, not a hands-on test.

Compare for your needs

For an explicitly ANSI-rated meeting-room choice, compare the released ViewSonic PJD7720HD; check its separate throw facts against the room.

Before you buy

What is the EH345 native resolution?

Optoma's data sheet specifies native Full HD 1920 × 1080 for the EH345.

Are its 3200 lumens ANSI lumens?

The Optoma sheet lists 3200 lumens but does not label the number ANSI, so this review keeps the method unknown.

How far from the screen does it sit?

Its 1.13–1.47:1 throw is conventional; use Optoma's chart and screen width for the final distance.

Does it include streaming apps?

The data sheet documents wired inputs but does not establish built-in apps; an external player can supply streaming services.
