Strengths & Weaknesses

BenQ ScreenBar Pro

+ Strengths
  • 1,000 lux center brightness with zero screen glare, per Cameron Dougherty Tech
  • Presence detection turns light on when you sit down and off after 5 minutes, fully automatic
  • Optional $20 magnetic webcam mount solves the 'camera above light bar' problem for single-monitor setups
Weaknesses
  • Touch-sensitive buttons on the bar are unresponsive and require precise tapping, per Cameron Dougherty Tech
  • Presence sensor can be tricked by chair placement, leaving the light on after you leave
  • At 50cm (20 inches) wide, it looks awkward on monitors smaller than 24 inches
Key flaw: The touch-sensitive buttons on top of the bar are bad.

Xiaomi Mi Computer Light Bar

+ Strengths
  • Frosted lens diffuses light into a soft, comfortable glow that reduces eye strain, per Switch and Click
  • Magnetic assembly between bar and clamp feels 'effortless and awesome' per Switch and Click
  • Does the same core job as $180 light bars for less than half the price
Weaknesses
  • Wireless dial feels cheap and wobbly, sounds like a 'Macarena' when shaken per Switch and Click
  • Adjusting color temperature requires holding down AND rotating the dial simultaneously. Unintuitive
  • USB-C port placement forces cable to wrap awkwardly around clamp, too short for standing desks
Key flaw: The wireless dial is cheap.

The Verdict

Our Bottom Line

The BenQ ScreenBar Pro won because it removes the one annoyance every other light bar forces on you: remembering to turn it on and off. Cameron Dougherty Tech tested the built-in presence sensor across weeks of daily use and confirmed it reliably activates when you sit down and shuts off after five minutes of absence. For a desk accessory that you interact with every single workday, that automation adds up.

For a desk accessory that you interact with every single workday, that automation adds up.

Best for:
  • Remote workers who want hands-free auto-dimming and presence detection for daily use
  • Single-monitor users who need BenQ's magnetic webcam mount to solve the camera placement problem
  • Owners of 24-inch or larger monitors who want the widest coverage (50cm bar)
  • Users who prefer touch controls on the bar itself over a separate desktop dial
  • Anyone willing to pay $139 once for a light bar that adjusts itself automatically for years

Switch and Click tested the Xiaomi Mi Computer Light Bar head-to-head against a $180 BenQ Halo and concluded they 'would still go with the cheaper option.' At $65, the Xiaomi delivers the core benefit of every monitor light bar: directed light on your desk without screen glare or eye strain.

Best for:
  • Budget-conscious buyers who want real eye strain reduction without paying the BenQ premium
  • Set-it-and-forget-it users who adjust brightness once and never touch it again
  • Standard flat-panel monitor owners who do not need specialized curved monitor clamps
  • First-time light bar buyers who are unsure if they will use it enough to justify $139+
  • Students and home office workers who want the core benefit without the smart features
