Monitor Light Bars Compared: BenQ Halo 2, Pro and a Dual-Screen Alternative
By The Gear Audit Team · Specification research September 9, 2026; buying-advice structure and manufacturer source check September 13, 2026.
Quick answer: monitor mount or desk clamp?
Choose BenQ ScreenBar Halo 2 when one compatible monitor needs front light plus rear illumination and you want its separate wireless controller. Choose ScreenBar Pro when front task lighting, integrated touch controls and a monitor mount are enough. Choose ScreenBar Max when a desk-clamp arm and wider dual-monitor coverage solve a real two-screen layout problem. Our recommendation is Pro for the simplest single-monitor starting point, Halo 2 only when rear light matters, and Max only after measuring the desk edge and arm clearance.
Halo 2 adds a rear light and separate controller. Pro keeps controls on the lamp and focuses on front lighting.
Max clamps to the desk and spans a broader work area, but needs desk-edge, height and behind-screen clearance.
The mounting method shapes the whole setup
| Buying question | ScreenBar Halo 2 | ScreenBar Pro | ScreenBar Max |
|---|---|---|---|
| Mounting format | Monitor-mounted bar | Monitor-mounted bar | Desk-clamp arm |
| Lighting distinction | Front light plus rear light | Front desk lighting | Broad dual-monitor desk lighting |
| Controls | Separate wireless controller with display | Integrated touch controls | — |
| Published fit or coverage | 0.17–2.36-inch monitor thickness; 1000R–1800R curve | 0.17–2.56-inch monitor thickness; 1000R–1800R curve | 135 × 58 cm coverage at the stated 500-lux threshold |
| Installation dependency | Compatible monitor edge and useful rear-light surface | Compatible monitor edge and reachable bar controls | Accessible desk edge, arm clearance and outlet |
| Best match | One screen with intentional front and rear lighting | One screen needing broad front light and on-lamp control | Measured two-screen desk with clamp clearance |
Halo 2 and Pro borrow the monitor’s upper edge; Max borrows the desk edge and airspace behind the screens. That is a larger difference than their brightness controls. Measure the mounting surfaces, camera location, monitor arms and shelf clearance before comparing secondary features.
ScreenBar Halo 2: front and rear lighting with a wireless controller
Best for: A compatible single-monitor setup where rear illumination is intentional and a separate desk controller is more convenient than reaching the lamp.
BenQ documents a front light, rear light and separate wireless controller with display. It provides stepless brightness adjustment and a 2700K–6500K color-temperature range. These are maker-described controls rather than evidence of reduced eye strain or independently measured glare.
The published monitor-fit range is 0.17–2.36 inches thick with stated support for 1000R–1800R curved monitors. That range does not guarantee fit around a webcam, unusual rear housing, top vent or protruding connector.
Pros
- Front and rear lights address two distinct surfaces. The bar lights the desk while the rear element can illuminate the area behind a monitor when that effect is wanted.
- The wireless controller moves adjustments onto the desk. Brightness and color temperature can be changed without reaching to the monitor’s upper edge.
Cons and trade-offs
- The rear light may add no value in an open or distant-wall setup. Buyers can pay for and accommodate a lighting element that does not suit the room geometry.
- The separate controller occupies desk space. It adds another object to place and keep accessible compared with Pro’s integrated controls.
- The monitor mount can compete with a webcam or unusual top bezel. Thickness and curvature ranges do not resolve every camera, vent and rear-housing conflict.
Choose something else if: Rear illumination is unnecessary or desk space for a separate controller is limited. ScreenBar Pro keeps its controls on the bar and focuses on front lighting.
Our recommendation
We recommend Halo 2 only when both rear lighting and the separate controller solve stated needs. Check the wall distance, monitor profile and camera together. If the rear element would illuminate open air or remain off, Pro is the more direct single-screen comparison.

ScreenBar Pro: front light with controls on the bar
Best for: A single-monitor workstation that needs broad front task lighting, has a compatible top edge, and does not need Halo 2’s rear light or desk controller.
ScreenBar Pro mounts to the monitor and places touch controls on the lamp. BenQ lists a thickness range of 0.43–6.5 cm, approximately 0.17–2.56 inches, and support for 1000R–1800R curves. Use the current Pro page rather than transferring the dimensions of another ScreenBar generation.
The USB-C connection describes the plug, not the electrical capability of every laptop or hub port. Confirm the power requirements and leave enough space to operate the controls without disturbing a webcam or tilting the screen.
Pros
- Integrated touch controls keep the desk clear of a separate dial. This is a simpler physical layout when reaching the bar is easy.
- The front-light design targets the work surface without a rear-light assembly. Buyers who do not need wall illumination get a more focused feature set.
Cons and trade-offs
- Every adjustment requires reaching the lamp. A high monitor, deep desk or limited shoulder reach can make the integrated controls less convenient than Halo 2’s controller.
- It does not provide Halo 2’s rear-light arrangement. Buyers who intentionally want light behind the monitor need another source or a different model.
- The top-of-monitor mount can conflict with cameras and unusual housings. The published thickness range alone cannot prove a clean fit.
Choose something else if: You want rear illumination or cannot comfortably reach the lamp controls. Halo 2 addresses both through its rear light and separate controller; Max avoids the monitor edge entirely.
Our recommendation
We recommend ScreenBar Pro as the first model to consider for a compatible single monitor when front lighting is the actual requirement. Measure the top edge and camera together, then verify the power source. The integrated controls are an advantage only if you can reach them comfortably.

ScreenBar Max: a desk-clamp arm for two monitors
Best for: A measured dual-monitor workstation with a usable desk edge and enough space for a clamp, arm and externally powered lamp.
BenQ identifies Max as a dual-monitor desk lamp with a desk-clamp arm and external power adapter. It publishes 135 × 58 cm coverage at a 500-lux threshold. That is a manufacturer-defined coverage specification, not a measurement at your mounting height or monitor arrangement.
The clamp avoids loading the monitor bezel, which can help with cameras or irregular housings. It transfers the fit problem to the desk: a rear apron, wall, shelf, monitor arm or cable tray can block the clamp or the lamp’s movement.
Pros
- The broad published coverage is designed around a two-screen work area. Max addresses a wider desk rather than asking one compact monitor bar to span both displays.
- The desk clamp leaves the monitor’s upper edge free. This can avoid direct competition with a webcam or top-bezel accessory.
- The arm provides placement options beyond a fixed monitor mount. Buyers can position the head around the screen arrangement within the arm and desk constraints.
Cons and trade-offs
- The clamp needs a compatible desk edge and clear underside. Aprons, cable trays, walls and built-in desks can prevent secure placement.
- The arm occupies space behind or around the monitors. Shelves and monitor arms can limit adjustment even when the clamp itself fits.
- The external power adapter adds a separate cable-and-outlet requirement. This is a larger installation than a compact monitor-mounted bar.
Choose something else if: The desk edge is inaccessible, the workstation has only one monitor, or an arm would conflict with shelves and monitor mounts. Halo 2 or Pro uses a compatible monitor edge instead.
Our recommendation
We recommend ScreenBar Max only after mapping the two monitors, desk clamp, arm sweep and outlet. Its broad stated coverage is useful when the physical installation works. For one screen, the clamp and arm are usually more structure than the job requires.

How to choose a monitor light
- Count and position the screens. One monitor favors Halo 2 or Pro; a genuinely wide two-monitor workspace is the reason to investigate Max.
- Measure the mounting surface. Record monitor thickness and curve for Halo 2 or Pro, or desk-edge thickness, underside clearance and wall distance for Max.
- Map accessory conflicts. Include the webcam, monitor arms, vents, rear housing, shelves and cable trays in a simple side-view sketch.
- Choose the control location. Decide whether reaching the bar is comfortable or a separate controller should remain on the desk.
- Verify power and returns. Check the exact cable, adapter and required power source, then use a return policy that allows a real fit check.
BenQ monitor-light FAQ
Does Halo 2 need a wall behind the monitor?
The rear light can illuminate the area behind the screen, so wall distance and room geometry affect its usefulness. BenQ’s feature does not guarantee the same visual result in open space.
Does ScreenBar Pro include rear lighting?
This comparison treats Pro as the front-light option. Buyers who specifically want BenQ’s front-and-rear arrangement should examine Halo 2.
Will Halo 2 or Pro fit with my webcam?
The monitor-thickness and curve ranges are only a starting point. Check the camera foot, bar mount, vents and rear housing together against the current installation instructions.
Is ScreenBar Max only for dual monitors?
BenQ positions Max as a dual-monitor desk lamp and publishes broad coverage for that use. It can be physically larger and more complex than needed for one screen.
Do the published lighting figures prove glare performance?
No. We did not measure glare, illumination or eye comfort. Published coverage and control specifications remain manufacturer claims.
