The original BenQ light bar and How-To Geek's best overall pick, with auto-dimming and controls on the bar. It costs more than similar bars, and curved-monitor fit is hit-or-miss.

Top complaints

  • Mixed fit on curved monitors

    How-To Geek lists 'mixed results on compatibility with curved monitors' as a con and notes some curved-monitor users reported problems.

  • Pricey for a basic bar

    How-To Geek lists 'pricey compared to similar light bars' as a con ($109 at the time).

  • Narrow monitor-thickness range

    How-To Geek says it fits flat or curved monitors 0.4 to 1.2 inches thick, narrower than the newer Pro (0.17-2.56 in per XDA).

What owners love

  • Auto-dimming and fine adjustment

    How-To Geek notes 15 brightness levels, 8 color-temperature levels (2,700-8,500 K) and auto-dimming toward 500 lux, peaking at 900 lux in the center.
