THE SHORT ANSWER

Our take

The BenQ HT2150ST is a native 1920 × 1080 DLP projector rated at 2200 ANSI lumens, with a 0.69–0.83:1 short-throw lens, 1.2× zoom, and two HDMI inputs. BenQ also specifies 16.7 ms input lag for 1080p at 60 Hz. Those features suit a home viewer or gamer who needs a relatively short conventional lens distance and native Full HD. It remains lamp-based and is not UST. The saved source-row offer was renewed; no claim about an individual unit's condition or accessories is made.

Consider it for

Home cinema or console gaming when native Full HD and a short conventional throw fit the room.

Look elsewhere if

It is not for ultra-short-throw furniture placement, built-in streaming apps, native 4K, cordless use, or buyers who cannot inspect an older lamp projector.

Pros & cons

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

What works in its favor

  • BenQ specifies a native Full HD 1920 × 1080 DLP image and 2200 ANSI lumens.
  • The 0.69–0.83:1 ratio and 1.2× zoom provide a documented short-throw placement range.
  • Two HDMI inputs, 10 W speakers, and a 1080p/60 input-lag specification suit a wired game setup.

What to weigh up

  • Short throw is not ultra-short throw; it still requires a measured lens-to-screen distance.
  • The lamp and optics need condition checks and no built-in streaming platform is documented.
  • A renewed source-row offer does not verify a unit's lamp hours, remote, or accessories.

What the features mean for you

Does its native Full HD panel match your screen?

BenQ lists the HT2150ST's native resolution as 1920 × 1080. That makes it a Full HD choice for a wide movie image or console display and gives it more native detail than the 720p Acer H5370BD or WXGA Epson Home Cinema 760HD. It is not native 4K. Match the screen size and viewing distance to the image detail you expect, and use the native value rather than a source's accepted input list when filtering. The resolution is a documented model specification; it does not certify the focus or pixel condition of an individual projector.

Will the short-throw lens fit where you sit?

BenQ gives a 0.69–0.83:1 throw ratio and 1.2× zoom. That is short throw, meaning the image can be formed from less distance than a standard lens, but it is not UST placement beside the wall. Measure lens-to-screen distance, desired diagonal, lens height, and mount position before comparing it with an ordinary-throw design. The manual's geometry helps plan a room, but it cannot confirm the available space in yours. Check the actual lens and focus behavior across the image on a used example.

How should gamers interpret the input-lag figure?

BenQ specifies 16.7 ms input lag at 1080p and 60 Hz. That is a manufacturer test specification for a stated mode and signal, not an independent measurement of every setting or source combination. A console setup should use the matching input and picture mode when comparing the figure, then check the controls and signal compatibility required by its games. Two HDMI inputs allow a wired console and another source to be connected. The cited pages do not establish integrated streaming, so an external player is still part of an app-based movie routine.

What do brightness and speaker ratings establish?

BenQ lists 2200 ANSI lumens and two 10 W chamber speakers. The ANSI label allows a like-for-like comparison with other products whose source uses that standard, but it does not describe a used lamp's remaining output. The built-in speakers may cover simple viewing, while room size and listening preference decide whether separate audio is needed. Check lamp hours, color uniformity, fan operation, zoom, focus, HDMI, and sound on the exact projector. A manufacturer's model specification is not a guarantee that an older or renewed unit retains original performance.

Who should compare the HT2150ST with another Full HD projector?

Choose the BenQ when its short throw, Full HD panel, wired HDMI, and source-specific lag figure match the room and play routine. LG PF1500 trades short-throw placement for a built-in digital tuner and legacy Smart TV system, while XGIMI HORIZON has integrated Android TV with separately stated ANSI and ISO brightness figures. Those models emphasize different setup needs. The HT2150ST offers no documented app platform and remains a lamp projector. Check the lens distance, lamp history, and exact accessories instead of treating the renewed offer as a condition report.

What else to compare

LG PF1500 adds a digital tuner and legacy Smart TV functions at native Full HD; XGIMI HORIZON has Android TV but a conventional throw and distinct ANSI/ISO ratings.

Before you buy

Is the HT2150ST ultra-short-throw?

No. BenQ lists a 0.69–0.83:1 short-throw lens; it still needs measured distance to the screen.

Is its input-lag figure tied to a particular signal?

Yes. BenQ specifies 16.7 ms at 1080p/60 Hz; other modes and setup conditions are not established by that figure.

Does it have streaming apps built in?

The saved BenQ documents list HDMI sources and speakers, not an integrated streaming-app platform.
