Quick verdict: Buy the Quntis Monitor Light Bar if you want the core benefits of a monitor light — glare-free desk lighting, auto-dimming, and zero desk footprint — for less money. Buy the BenQ ScreenBar if you want the original, refined design from an established monitor maker and are happy to pay more for it. On paper the two share the same essential features, so the BenQ is a quality-of-execution upgrade rather than a different kind of product.

The Core Question: Is the BenQ Worth It Over a Budget Alternative?#
The BenQ ScreenBar created the monitor light bar category. It sits on top of your monitor, lights the desk in front of you, and keeps that light off the screen so you get no glare or reflection. It became popular because it solved a real problem — lighting a desk at night without washing out the display or taking up space with a lamp.
The Quntis Monitor Light Bar follows the same formula. Compare the feature lists side by side and the overlap is striking: both use an asymmetric optical design to keep light off the screen, both have an ambient light sensor for auto-dimming, both are USB-powered, and both are rated for high color accuracy. For most people, the Quntis delivers the main benefit of a light bar at a lower cost.
What the BenQ adds is the confidence of the original design and brand. If you want the version most other light bars are modeled on, that is what you are paying for.
Glare Control and Optics#
Glare control is the reason to buy a monitor light at all. BenQ's ASYM optics are designed to direct light down and forward onto the desk at an angle that keeps it off the screen. Quntis describes its own asymmetric beam the same way: light on the desk, no screen glare.
Both are designed to achieve the same result. If you mainly want to stop a desk lamp from reflecting off your monitor, either bar addresses the problem.
Color Accuracy and Auto-Dimming#
BenQ rates the ScreenBar at CRI above 95, and Quntis rates its bar at Ra98. Both figures describe high color rendering, meaning paper, skin tones, and objects on your desk look natural rather than washed out. For reading, writing, and general desk work, the two are effectively equal on this spec.
Both also include an ambient light sensor that adjusts brightness automatically as the room gets darker or brighter. The Quntis lists stepless dimming alongside its auto mode, so you can fine-tune brightness manually too.
Mounting, Controls, and Power#
Both bars rest on top of the monitor and hang a weighted clip behind it, so neither needs screws or desk space. Quntis notes that its weighted clip may not suit very thin or curved bezels, and the same caution is worth applying to any clip-on bar: check your monitor's top edge and back before buying.
Controls on both are on the bar itself, so you reach up to the top of the monitor to adjust them. Both run on USB power, which keeps setup simple — you can often plug into a monitor's USB port — but it also sets a brightness ceiling. Neither bar includes a backlight to light the wall behind the monitor; BenQ's ScreenBar Halo 2 adds a rear glow for that.
Who Should Buy Which#
Choose the BenQ ScreenBar if you:
- Want the original, refined light bar design from an established brand
- Are willing to pay more for build and brand confidence
- Plan to keep the light for years and want the category benchmark
Choose the Quntis Monitor Light Bar if you:
- Want glare-free, auto-dimming desk lighting for less money
- Like the option of stepless manual dimming alongside auto mode
- Are trying a monitor light for the first time and want a low-risk entry point
Frequently Asked Questions#
Is the BenQ ScreenBar worth it over a cheaper light bar?#
It depends on what you value. The Quntis matches the BenQ's core features on paper: asymmetric glare-free optics, an auto-dimming sensor, USB power, and high color rendering. The BenQ is worth it if you want the original design and an established brand; otherwise the Quntis covers the same essentials for less.
Do monitor light bars cause screen glare?#
Well-designed ones should not. Both the BenQ ScreenBar and the Quntis use asymmetric optics that aim light down onto the desk and away from the screen, which is the main reason to choose a light bar over a desk lamp.
Will a monitor light bar fit a curved monitor?#
Check before buying. Clip-on bars like these rest on the top edge of the monitor and hang a weighted clip behind it, and Quntis notes its clip may not suit very thin or curved bezels. Models designed specifically for curved monitors are a safer choice for those screens.
Can a monitor light bar replace a desk lamp?#
For most desk tasks, yes. A light bar lights the area in front of your keyboard without taking up desk space. Because both bars are USB-powered, they are best as focused task lighting rather than a replacement for room lighting.
The Verdict#
The BenQ ScreenBar is still the benchmark monitor light, with ASYM optics, auto-dimming, and high color accuracy in a refined package. But the Quntis Monitor Light Bar matches its core features closely, which makes it the better value for most desks. Buy the BenQ if you want the original; buy the Quntis if you want the same everyday benefit for less. See our full desk lighting reviews for more options.
