Third-party reviews

Based on ratings from across the web.
Reviews last updated: October 2026 · How we calculate this

What customers like about LG CineBeam HU70LS

  • Excellent 4K image sharpness and detail thanks to pixel-shifting technology
  • Vibrant and natural color reproduction using a 4-channel LED light source
  • No 'rainbow effect' issues because it does not use a traditional color wheel
  • Long-lasting light source rated for up to 30,000 hours with no bulb replacements needed
  • User-friendly webOS smart platform with built-in streaming apps like Netflix and Disney+
  • Very quiet operation, especially compared to bulb-based projectors
  • Compact and lightweight design makes it easy to set up or move
  • Responsive Magic Remote with backlighting and voice control

What customers don't like about LG CineBeam HU70LS

  • Poor contrast and black levels, often described as looking more like dark grey
  • Brightness is insufficient for rooms with moderate to high ambient light; best used in dark environments
  • Built-in 3W speakers are weak and lack bass, making external audio essential
  • Limited installation flexibility due to a lack of horizontal lens shift and vertical-only keystone correction
  • HDR performance is underwhelming because of low peak brightness and contrast
  • Input lag is relatively high (around 52ms), which may not suit competitive gaming
  • Power supply brick is notably large and heavy relative to the projector's size
  • Some users reported difficulty achieving perfect focus across the entire screen simultaneously

Verdict

The LG CineBeam HU70LS is a compact 4K UHD DLP projector featuring a 4-channel wheel-less LED light source that delivers 1,500 ANSI lumens of brightness and covers 92% of the DCI-P3 colour gamut. Its standout characteristics include a massive 30,000-hour lifespan, HDR10 with dynamic tone mapping, and integrated webOS 4.5 for seamless smart TV functionality using the included Magic Remote. Main pros include its maintenance-free LED engine that eliminates the 'rainbow effect,' quiet operation at roughly 30dB, and excellent motion handling via TruMotion technology. However, it suffers from limited native contrast with 'greyish' black levels, lacks 3D support, and has restricted placement flexibility due to the absence of horizontal or vertical lens shift.
