BenQ ScreenBar Review

What's Included

Build & Buttons

The ScreenBar's frame and clip are built with aluminum and polycarbonate. The clip has a built-in counterweight to allow you to attach the lamp to the top of your monitor without permanence. You can also rotate the lamp within the clip to the desired position.

Another exciting feature (if you get excited about these kinds of things) is that the whole assembly is USB powered. If your monitor has built-in USB ports this is especially convenient. Although, if the USB ports are on the side of your monitor, you may want to invest in a right angle USB cable or adapter to keep it's appearance streamlined.

There are four touch-sensitive buttons on the top of the device. There is a dimmer button to adjust the brightness, a hue adjustment button to change the color temperature, an auto dimmer button, and a power button. You'll also see a small ambient light sensor on the top as well.


BenQ claims that the lamp is compliant with "IEEE PAR1789 regulation of flicker in LED lighting." It is also free of any blue-light hazard by passing an "IEC/TR 62778 assessment."

While I can't scientifically test the quality of the light, I can say that I haven't noticed any eye strain after using it for several hours at a time. There's no glare on my monitor itself, and it's incredibly easy to write in a notebook or read a textbook on your desk without fighting shadows.

Because of this, I don't feel like I have to hunch over, move closer, or dodge shadows and glare when working on something. This has had the inadvertent effect of improving my posture. Because my eyes aren't the best (I wear glasses), having plenty of light at my desk has undoubtedly improved my productivity.

As a bonus, it also provides great lighting for thumbnails. The Cherry MX Board 5.0 thumbnail used the ScreenBar to provide the light for the shot.


The color temperature can be adjusted between a warm 2700K all the way to a cool 6500K.

Unfortunately, some units are defective. The auto-dimming and auto hue adjustment (in other words, the ambient light sensor) has quality control issues. You may want to immediately check to see if the feature works for you if you decide to make a purchase. For me, the feature was inoperable. It's a shame because I would love to check it out and show how it works in this review.

Dimensions and Fit

The clip is said to fit any monitor with a thickness from 1 to 3 cm (0.4" to 1.2"). A reviewer on Amazon has stated that the clip works on their monitor with a thickness of 1.5". My ASUS PA248Q Monitor has a thickness of 1.1", but it looks like the clip could fit up to 1.3" with no issue, depending on how your monitor is designed.

Once you have it in place, the counterweight balances the lamp unto the top of your monitor. I gave the USB cable a tug to test the security of the clip, but it doesn't seem to be going anywhere.

Pricing / Availability


Other than the note above about some defective units, I have nothing negative to say about this lamp. This may be the first time I have ever reviewed a product without at least one quibble. It illuminates your entire desk with even bright light. It allows you to adjust the color temperature and brightness. It's USB powered. It's sleek, and the clip is well designed. I'm not sure what else you need in a desk lamp, but this is the best one I have ever used.


BenQ sent this product to me for review. If you would like to support Rhinofeed you can purchase it on Amazon..
