BenQ's Screen Bar Max is the first monitor light bar designed for dual-monitor setups, combining a bias light and desk lamp to reduce eye strain. Priced at $289 with an optional $39 stand, it's the most expensive Screen Bar product to date. The lamp features presence sensing using a high-frequency mmWave sensor that activates only when the user sits down, avoiding false triggers from walking or chair movement.

Brightness for bias and desk lighting can be controlled independently, though temperature (2,700–6,000K) is fixed across both. A single mode selector button requires toggling to adjust individual lights, which the reviewer notes as a minor inconvenience justified by the premium price. The Screen Bar Max delivers exceptional light quality, described as 'pristine,' 'precise,' and 'heavenly,' with a CRI of Ra ≥95, Rf >96, and Rg ~100.

While cheaper alternatives offer similar functionality, none match its build, sensor precision, or light fidelity. The reviewer concludes that despite the steep cost, the Screen Bar Max justifies its price through performance and thoughtful design for multi-screen users.
