What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it

Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.8 for now.

Third-party reviews

What customers like about LG BX275

  • High brightness for its class (2,700 Lumens), suitable for moderately lit rooms
  • Compact and lightweight design (approx. 2.3 kg) for easy portability
  • Built-in 2W mono speaker provides basic internal audio without extra equipment
  • Energy-efficient performance with relatively low power consumption (260W)
  • Includes a sleep timer and a remote control for convenient operation
  • 3D-capable with DLP technology for reduced pixel visibility and higher contrast

What customers don't like about LG BX275

  • Dated XGA (1024x768) native resolution lacks the sharpness of modern HD/4K models
  • Internal speaker is underpowered (2W) for large meeting rooms or cinemas
  • Lacks modern connectivity options like HDMI (includes VGA and USB instead)
  • Audible fan noise (36 dB) can be noticeable in quiet environments
  • Limited lamp life (3,500 hours) compared to modern LED or laser projectors
  • No motorized focus or motorized zoom features

Verdict

The LG BX275 is a compact, business-oriented DLP projector featuring a high brightness of 2,700 ANSI lumens and an XGA native resolution (1024 x 768). It utilizes BrilliantColor technology with a 6-segment color wheel to deliver enhanced vibrancy and depth, supported by a 2,200:1 contrast ratio. Main advantages include its portable 2.31 kg frame, a long lamp life of up to 4,000 hours in Eco mode, and a filter-free design that minimizes maintenance costs. However, its primary drawbacks are the lack of motorized focus or zoom and a native aspect ratio of 4:3, which may feel outdated for modern widescreen content.
