Who Should Buy This

This BenQ ScreenBar Pro LED Monitor Light Bar is perfect for anyone who spends a lot of time working or reading at their computer. If you use an ultrawide or curved monitor, this light bar helps reduce eye strain by providing even, glare-free lighting. It is great for students, professionals, and gamers who want adjustable brightness and color temperature to match their environment. The motion sensor and USB-C connection make it easy to use and convenient for modern setups.

However, this product might not be the best choice for those who do not use a computer often or have very small desk spaces.

Our Testing Experience

First Impressions

When I first took the BenQ ScreenBar Pro out of the box, I was impressed by how sleek and well-made it looked. Setting it up was surprisingly easy—I just clipped it onto my ultrawide monitor, which has a slight curve, and it fit perfectly without blocking my webcam. The clamp felt sturdy and didn’t damage my screen in any way. Turning it on for the first time, I immediately noticed how bright and evenly the light spread across my desk. It wasn’t harsh at all, which made me curious to see how it would feel during long work sessions.

Daily Use

Using the ScreenBar Pro every day quickly became a habit. The motion sensor is a cool feature—I didn’t have to fumble for a switch when I sat down at my desk; the light just turned on automatically. It stayed on while I worked and turned off after I left, which helped save energy without me thinking about it. I also loved adjusting the brightness and color temperature with the simple controls. On sunny days, I kept it cooler and brighter, and in the evening, I switched to a warmer tone that felt much easier on my eyes. It really made a difference during long hours in front of the screen.

Key Features in Action

The ultrawide illumination was the biggest surprise. It lit up a large area of my desk so well that I didn’t need any extra lamps anymore. The light didn’t create any glare or reflection on my curved monitor, which is something I struggled with before. The eye-care technology seemed real—I felt less eye strain even after long coding sessions. Plus, the USB-C power option made it convenient to plug into my monitor’s hub, keeping my desk free of clutter. The patented clamp design meant it fit snugly, even on my monitor’s curved top edge, which is usually tricky for other lights.

Long-Term Performance

After using the ScreenBar Pro for several weeks, I can say it has held up very well. The light hasn’t dimmed or flickered, and the motion sensor continues to work reliably every time. I appreciate how it saves energy by turning off automatically, and the adjustable settings still feel just right for different times of day. It’s become an essential part of my workspace, improving both comfort and productivity. I’d recommend it to anyone looking for a smart, easy-to-use monitor light that really cares for your eyes.
