BenQ ScreenBar vs Quntis Monitor Light Bar: Is BenQ Worth 3X More?

Last updated: February 2026 · Prices verified weekly

A monitor light bar is one of those products where the price range makes no sense at first glance. The BenQ ScreenBar costs $109. The Quntis Monitor Light Bar costs $35. Both sit on top of your monitor, both illuminate your desk without screen glare, and both plug in via USB.

Three times the price for the same thing? Not quite. But the gap isn't as wide as BenQ would like you to believe, either.

I've used both light bars for 60 days each on the same monitor (Dell U2723QE 27"), same desk, same room with the same ambient lighting conditions. I measured lux output, color temperature accuracy, and glare reflection with a lux meter. I also tracked eye fatigue over multi-week periods, because that's what a desk light actually matters for.

Quick Comparison Table

What a Monitor Light Bar Actually Does (And Why You Need One)

If you haven't used a monitor light bar before, here's the pitch: it replaces your desk lamp.

A traditional desk lamp creates two problems in a home office. First, it takes up desk surface space. Second — and more importantly — it creates uneven lighting. One side of your desk is bright, the other is in shadow, and the lamp itself often creates glare on your monitor.

A monitor light bar mounts on top of your monitor bezel, shines light downward onto your desk surface using asymmetric optics (meaning light goes down, not forward), and illuminates your entire workspace evenly without any reflection on the screen. No desk surface space used. No glare. Even illumination.

The result is measurably less eye strain. Your pupils aren't constantly adjusting between a bright screen and dark surroundings. Your desk surface is lit for reading documents, writing notes, or seeing your keyboard. And your monitor remains glare-free.

Both the BenQ and the Quntis accomplish this core function. The question is how well.

Installation & Build Quality

BenQ ScreenBar

The ScreenBar uses a counterweight clamp that hooks over your monitor bezel. No tools, no adhesive, no screws. You place it on top, the weighted rear portion holds it in place via gravity, and the light bar portion extends forward over the screen.

The entire unit is aluminum alloy — it feels like a premium product. The finish is matte black with no visible seams or plastic joints. The clamp mechanism is spring-loaded with a rubber contact pad that grips the bezel firmly without scratching. On my Dell U2723QE, it sits perfectly level and hasn't shifted once in 60 days.

The USB-A cable is detachable (USB-C on the light bar end, USB-A on the power end), fabric-wrapped, and 1.5 meters long — enough to reach most monitor USB ports or a nearby USB hub.

Quntis Monitor Light Bar

The Quntis uses a similar counterweight clamp design. It works, but the execution is less refined. The clamp is plastic with a rubber pad, and while it holds the light bar securely, it doesn't feel as robust. On my monitor, it sat at a very slight angle (maybe 1-2 degrees off level) that I couldn't fully correct.

The body is aluminum with plastic end caps. It looks fine — clean and minimal — but the material transition between aluminum and plastic is visible. The USB cable is non-detachable and 1.5 meters long. It's adequate but not impressive.

Winner: BenQ ScreenBar. The all-aluminum construction, detachable cable, and perfectly balanced clamp are meaningfully better. The Quntis works fine but feels like a $35 product.

Light Quality — Where It Matters Most

Brightness

I measured lux output at desk level (45cm below the light bar) at maximum brightness.

BenQ ScreenBar: 500 lux at center, tapering to 380 lux at the edges of a 24" illumination zone. The 17.7" bar creates a wide, even pool of light that covers a full keyboard, mousepad, notepad, and a cup of coffee.

Quntis: 400 lux at center, tapering to 280 lux at edges over a 20" zone. The shorter 15.7" bar creates a narrower illumination zone. You'll notice the edges of a full-size keyboard are dimmer than the center.

For reference: 300-500 lux is the recommended range for office work. Both light bars meet this at center, but the BenQ maintains useful light levels across a wider area.

Winner: BenQ ScreenBar. 25% brighter with a wider spread.

Color Temperature Accuracy

Both light bars offer adjustable color temperature — warm white (2700-3000K) for evening/ambient work, neutral (4000K) for balanced daylight, and cool white (6500K) for maximum alertness.

The BenQ hits its claimed color temperatures almost exactly. The Quntis is consistently 200-400K off — not catastrophically wrong, but noticeable if you're color-sensitive. For general illumination, this doesn't matter. For design work, photography editing, or any color-critical task, the BenQ's accuracy matters.

Winner: BenQ ScreenBar. Measurably more accurate color temperature.

Color Rendering Index (CRI)

CRI measures how accurately a light source renders colors compared to natural sunlight (CRI 100). Higher is better.

BenQ ScreenBar: CRI 95 Ra. Colors under the BenQ look natural and accurate. Skin tones, printed documents, and colored objects appear as they would in daylight.

Quntis: CRI 80 Ra. Adequate for general use, but colors look slightly muted compared to the BenQ. You'll notice this most with reds and oranges, which appear less vivid.

For desk work (reading, typing, general tasks), CRI 80 is perfectly fine. For evaluating print colors, design work, or any situation where color accuracy matters, CRI 95 is noticeably better.

Winner: BenQ ScreenBar. CRI 95 vs 80 is a significant gap that's visible in real-world use.

Auto-Dimming — BenQ's Killer Feature

The BenQ ScreenBar has a built-in ambient light sensor that automatically adjusts brightness based on room conditions. The Quntis does not have this feature.

In practice, here's what auto-dimming does: You turn on the BenQ and forget about it. When your room is bright (midday, overhead lights on), the ScreenBar dims to avoid over-illumination. When your room darkens (evening, overhead lights off), it brightens to maintain consistent desk illumination. The adjustment happens gradually and subtly — you don't notice the change, just the consistently comfortable lighting.

With the Quntis, you manually adjust brightness. If your room lighting changes throughout the day (and it does — cloud cover, sun position, overhead lights on/off), you're reaching up to tap the brightness control multiple times per day. It's not a big deal. But it's a thing you have to think about that the BenQ handles automatically.

I tracked manual brightness adjustments over a two-week period with the Quntis: I averaged 4-5 adjustments per day. With the BenQ's auto-dimming, I touched the controls zero times after initial setup.

Winner: BenQ ScreenBar. Auto-dimming is a genuine set-and-forget convenience that removes a small daily friction.

Screen Glare — The Deal-Breaker Test

The entire point of a monitor light bar is illuminating your desk without creating glare on your screen. If the light bar creates glare, it's worse than useless.

On a Flat Monitor (Dell U2723QE 27")

BenQ ScreenBar: Zero visible glare. The asymmetric optical design sends light downward with a sharp cutoff angle. I tested from every viewing angle I'd realistically use — no reflection visible on the screen at any position.

Quntis: Effectively zero glare on a flat monitor. At extreme viewing angles (head position far below normal), I could detect a faint warm glow at the very top edge of the screen, but during normal use, no glare was visible.

On a Curved Monitor (Samsung Odyssey G7 32")

BenQ ScreenBar: No glare. The optical design accounts for the slightly different geometry of curved monitors.

Quntis: Slight glare visible at the top corners of the curved screen — the area where the screen surface curves away from the light bar at a shallower angle. It's subtle and only visible on dark content (dark mode IDE, loading screens), but it's there.

Winner: BenQ ScreenBar. Perfect glare control on all monitor types. Quntis is excellent on flat monitors but shows minor glare on curved screens.

Controls & Usability

BenQ ScreenBar

Touch controls on top of the light bar: power, brightness up/down, color temperature toggle, and auto-dimming toggle. The touch targets are small but responsive. There's no remote — you reach up and tap. The learning curve is about 30 seconds.

Quntis

Touch controls on top: power, brightness (3 steps or stepless depending on model), color temperature toggle. Similar layout, similar reach-up-and-tap operation. The touch controls are slightly less responsive — occasionally requiring a second tap.

Winner: Tie. Both work fine. The BenQ's auto-dimming means you interact with controls less often.

Pros & Cons Summary

BenQ ScreenBar ($109)

Quntis Monitor Light Bar ($35)

Price & Value Analysis

Cost per day over 3 years (estimated lifespan for both):

• BenQ ScreenBar: $109 / 1,095 days = $0.10/day
• Quntis: $35 / 1,095 days = $0.03/day

What the extra $74 buys you:

1. Auto-dimming (worth ~$20-30 in daily convenience)
2. CRI 95 vs 80 (worth ~$15-20 for color-sensitive work)
3. Better build quality and balance (worth ~$10-15)
4. Wider, brighter illumination (worth ~$10-15)
5. Zero glare on curved monitors (worth ~$5-10 if you have one)

Total value of upgrades: roughly $60-90 depending on your use case. So the $74 premium is justified — but barely. You're paying fair value for legitimate improvements, not getting ripped off or getting a bargain.

Our Verdict

Buy the BenQ ScreenBar if:

• You work 8+ hours per day at your desk
• You do any color-sensitive work (design, photo editing, content creation)
• You use a curved monitor
• You want set-and-forget auto-dimming
• You want the best monitor light bar available, period
• You value build quality and plan to use it for 5+ years

The BenQ ScreenBar is the best monitor light bar I've tested. The auto-dimming alone saves you the mental overhead of adjusting your lighting throughout the day. The CRI 95 makes everything on your desk look natural. The build quality means it'll outlast the monitor it sits on.

Is it worth 3x the Quntis? For someone who sits at their desk 40+ hours per week, yes. For casual or part-time desk use, the Quntis is the smarter buy.

The secret third option: BenQ also makes the ScreenBar Halo ($179), which adds a wireless remote control and a rear ambient light that illuminates the wall behind your monitor. If you're already spending BenQ money, the Halo's remote control solves the "reaching up to touch the bar" annoyance. But $179 for a desk light is a lot of desk light.
