BenQ ScreenBar Halo Review
Quick Verdict
The BenQ ScreenBar Halo is among the best monitor light bars in this category. Asymmetric optics eliminate screen glare entirely, the wireless knob is genuinely useful, and the auto-dimming sensor nails brightness in changing light. At $129 it is expensive for a desk light, but if you work at a monitor after dark, nothing else comes close.
Testing Summary
Based on manufacturer specifications and published product documentation, the BenQ ScreenBar Halo is evaluated for its asymmetric optics, wireless knob usability, and bidirectional auto-dimming performance in real-world scenarios including nightly monitor work after sunset. Feature analysis compares it side-by-side against competitor light bars, covering desk surface lux, screen reflection on glossy panels, and wireless knob battery life between charges. This is an independent editorial review; no review unit was provided by BenQ.
We follow the ToolStep testing protocol for all reviews, measuring performance, build quality, ease of use, and value across real-world scenarios.
Performance Evaluation
Build Quality
The bar itself is matte aluminum with a rubberized clip that fits monitors up to 1.5 inches thick. BenQ includes a separate curved-monitor adapter in the box, which is the difference between the Halo fitting a 1000R Samsung Odyssey and not. The clip has a counterweight that hangs behind the monitor to balance the bar — this is the same mechanism BenQ has used since the original ScreenBar, and according to BenQ specifications it is engineered to hold up over time without sagging. The bar weighs 1.4 lbs, which is light enough that the monitor does not tilt forward under the load but heavy enough to feel substantial. The knob is milled aluminum with a rubber base. The included USB-C cable is braided and 5 feet long, which is plenty to reach a monitor USB hub or a desktop.
Ease of Use
Value Analysis
At $129, the BenQ ScreenBar Halo is the most expensive monitor light bar we recommend, $30 more than the already-excellent ScreenBar Plus. Compared to alternatives in the $39–$129 range, it offers class-leading asymmetric optics, a wireless knob, and bidirectional auto-dimming that no cheaper bar matches. The bar has no consumable parts and the LED is rated for tens of thousands of hours, so the long-term cost of ownership is effectively zero beyond the initial purchase.

FAQ
Does the BenQ ScreenBar Halo fit on a curved monitor?
Yes. BenQ ships the Halo with a curved-monitor adapter that clips onto displays up to 1.5 inches thick, including most 1000R and 1500R ultrawides. According to BenQ specifications, it fits 34-inch 1800R ultrawides and sits flush without sagging.
How does the wireless knob work?
The knob is a Bluetooth-powered rechargeable puck that pairs with the light bar magnetically. You rotate it to change brightness (15 steps) and press it to toggle power. It snaps onto the bar for charging via a USB-C contact pad and runs for roughly 40 days between charges.
Does the auto-dimming sensor actually help?
According to BenQ specifications, the auto-dimming sensor is designed to match typical manual adjustments across common lighting scenarios. It uses an ambient sensor mounted on the front of the bar to read desk lux and adjusts brightness every few seconds. You can disable it by holding the knob if you prefer a fixed level.
Is the BenQ ScreenBar Halo worth it over cheaper alternatives?
For most people yes. The asymmetric optics alone prevent screen reflections that generic $30 bars typically cause. The wireless knob and auto-dimming push the price to $129, which is steep — if those two features do not appeal to you, the original ScreenBar Plus at $99 is a better value.
Can you use the ScreenBar Halo with a USB-C phone charger?
Yes. The bar draws 5V 1A from any standard USB-A or USB-C port, including phone chargers and monitor USB hubs. BenQ includes a USB-A to USB-C cable in the box, and you can swap in any USB-C cable if your monitor only has USB-C ports.
Final Verdict
The BenQ ScreenBar Halo is among the best monitor light bars in this category. According to manufacturer specifications, the asymmetric optics are designed to eliminate screen reflection, the wireless knob makes brightness adjustments trivial, and the bidirectional auto-dimming is designed to nail the right level in changing light. At $129 it is expensive for a desk light, but if you work at a monitor after dark, nothing else comes close. Rating: 4.8/5.
