BenQ ScreenBar Halo 2 Review (2026)
In-depth review of the BenQ ScreenBar Halo 2: front and back light, wireless controller with display, curved monitor fit, and flagship pricing.
BenQ ScreenBar Halo 2
BenQ's flagship: front light, backlight, wireless controller, and curved monitor fit.
Our verdict
The Halo 2 is the most complete monitor light bar you can buy: front light with Ra95 colour, a backlight that tames night contrast, a wireless controller that shows exact settings, and a mount that fits monitors other bars reject. It is also the most expensive bar here, and most users will set it once and rarely touch it again, which makes the premium a luxury rather than a necessity. Buy it if your desk is curved, large, or used late at night; buy the Plus if it is not.
What we like
- Front light plus backlight lets you balance desk brightness against wall glow, cutting eye strain in dark rooms.
- Wireless controller with a display shows exact brightness and colour temperature, so adjustments are precise rather than guessed.
- Fits flat and curved monitors from 0.43 to 6 centimetres thick, covering ultrawide curved displays other bars reject.
What to watch out for
- The highest price in this guide, and the controller needs charging or battery care over time.
- More features than most users need daily, since most owners settle on one setting and leave it.
- Larger footprint and weight than simpler bars, so small desks feel the difference.
Who it is for
Ultrawide and curved monitor owners, night workers, and buyers who want the full lighting system rather than a single bar.
Front and back light together
The Halo 2 lights the desk with a high-accuracy front beam (Ra95 or better) and glows on the wall behind the monitor with its backlight. Used together, they balance the room: the desk is bright enough to work, the wall is bright enough that the screen does not float in darkness. That balance is the most noticeable comfort gain over front-only bars during late sessions, and it is the feature owners cite most after buying.
The controller with a display
The wireless controller shows brightness and colour temperature numerically, so you can return to an exact setting instead of guessing by feel. That sounds minor until you share a desk or switch between day and night setups, when repeatability matters. Wireless placement also means the controller sits wherever your hand rests, not where the cable reaches.
Curved monitor fit
The Halo 2 fits flat and curved monitors from 0.43 to 6 centimetres thick, the widest range in this guide, including aggressive ultrawide curves that defeat narrower clips. An optional webcam accessory addresses the top-centre camera problem on displays with built-in webcams. If your monitor rejected a previous bar, this is the bar to try next.
How it stacks up
Against the ScreenBar Plus, the Halo 2 adds backlight, wireless control, and curved fit at roughly double the complexity and a higher price. Against the ScreenBar Halo (first generation), it adds a better controller display, wider fit, and brighter output. Against the Quntis remote bar, it is the premium version of the same idea: better optics, better controls, and a price to match.

Questions, answered
Is the Halo 2 worth it over the Plus?
For curved monitors, night workers, and shared desks, yes: backlight, controller display, and fit range justify it. For a standard flat monitor used in daylight, the Plus gives the same front light for less.
Does the controller need charging?
Yes, the wireless controller charges over USB-C. Battery life covers weeks of normal use, but keep the cable handy so a dead controller never leaves you without light control.
Will the Halo 2 block my webcam?
Possibly, on monitors with a top-centre webcam. BenQ offers a webcam accessory for the Halo 2, and sliding the bar slightly to one side also works for most calls.
