BenQ LH860ST

Manufacturer: BenQ

The BenQ LH860ST is a short-throw laser projector designed for environments where image brightness and wireless flexibility matter. Built around a laser light source, it delivers consistent illumination without the maintenance concerns associated with traditional lamp-based units. The projector supports a dedicated smartphone app and includes built-in smart TV functionality, making it a self-contained unit for a range of use cases.

On the technical side, the LH860ST outputs at 4K resolution with a brightness rating of 5000 ANSI lumens and a 60Hz refresh rate, while supporting HDR10 and HLG for broader content compatibility. Wireless connectivity options include Wi-Fi, Bluetooth, AirPlay, Chromecast, and Miracast, complemented by one HDMI port and one USB port. Audio is handled by stereo speakers rated at 2 x 5W, and a 3.5 mm headset jack is available for external audio output. The unit weighs 5200 g and measures 343.8 x 136 x 265.5 mm, with a maximum projection size of 300″ and a minimum throw distance of 1.1 m.

Pros
  • Laser light source eliminates the need for lamp replacements over time
  • 5000 ANSI lumens provides strong brightness output for a projector in this category
  • 4K output resolution ensures sharp, detailed image reproduction
  • Wide wireless connectivity including Wi-Fi, Bluetooth, AirPlay, Chromecast, and Miracast covers most streaming and mirroring needs
  • Built-in smart TV functionality allows standalone use without an external media source
  • Short minimum throw distance of 1.1 m offers flexibility in room placement
Cons
  • No vertical or horizontal lens shift limits image alignment flexibility after placement
  • Only one HDMI port restricts simultaneous wired device connections
  • No RJ45 ethernet port means a stable wired network connection is not possible
  • 3D content playback with glasses is not supported
  • No external memory slot prevents direct local media playback from cards or drives
  • Warranty period is limited to 1 year
Who is this for?

This projector is well-suited for large-venue or professional installation environments where consistent, high-brightness output is essential — the 5000 ANSI lumens laser light source maintains reliable illumination even in spaces with ambient light. Its 4K resolution and HDR10/HLG support make it a practical fit for presentation or display setups demanding sharp image quality, while the broad wireless connectivity options including AirPlay, Chromecast, and Miracast, combined with built-in smart TV functionality, suit users who need flexible, cable-light operation across multiple devices.

Who is this NOT for?

Users who require precise image geometry adjustment will find the complete absence of vertical and horizontal lens shift a significant limitation, as placement flexibility is considerably reduced. The projector is equally unsuitable for those who need multiple simultaneous wired connections, given that only a single HDMI port is available and no RJ45 ethernet port is present. Additionally, users who rely on local media playback from memory cards or external storage will be hindered by the lack of an external memory slot.
