The Ultimate Guide to Choosing the Best Monitor Light Bar

Ever found yourself squinting at your computer screen late at night or struggling to read documents in dim light? A monitor light bar can help illuminate your desk without taking up extra space—but choosing the right one isn’t just about brightness. 

Your monitor type, desk layout, room lighting, and the number of screens you use all affect which light bar fits best. A single flat monitor, a curved or ultrawide screen, a dual-monitor setup, and an iMac workspace each require different lighting coverage, mounting design, and glare control.

In this guide, we’ll walk you through the key factors to consider before buying a monitor light bar, so you can find the right ScreenBar for the way you work, create, code, or spend long hours in front of your screen.

A monitor light bar is a lighting accessory that sits on or above your monitor to illuminate your desk area. Unlike a traditional desk lamp, it is designed to save desk space and direct light toward your keyboard, documents, and work surface instead of shining directly into your eyes or reflecting on the screen. 

BenQ ScreenBar takes this idea further with ASYM-Light™ technology, which helps direct light onto the desk while keeping it away from the screen and your eyes. This makes it especially useful for people who spend long hours in front of a screen, work in dim environments, or want a cleaner desk setup without adding another lamp base.

A monitor light bar is not just a smaller version of a desk lamp. It is designed for screen-based workspaces, where the goal is not only to make the desk brighter, but to place the right amount of light in the right area without disturbing your screen or your eyes. 

According to the American Optometric Association, poor lighting and glare on a digital screen can contribute to digital eyestrain. A well-designed monitor light bar helps reduce this problem by managing direct glare, reflected glare, and contrast glare around your screen. 

A monitor light bar provides focused lighting for your keyboard, documents, notebook, and work surface, making it easier to see in dim environments.  
 
For comfortable screen work, lighting should be bright enough, with 500 lx recommended by the American National Standard Practice for Office Lighting (ANSI) as a reference level for task-area lighting, and spread evenly across your field of view. This aligns with CCOHS lighting guidance, which identifies insufficient light, glare, improper contrast, and poorly distributed light as common lighting problems.

By mounting on or above your monitor, a monitor light bar frees up the space that a traditional desk lamp would take. This helps reduce desk clutter and keeps your workspace cleaner, especially when monitors, keyboards, notebooks, speakers, tablets, and other accessories already occupy most of the desk.

Understanding the myriad benefits of monitor light bars helps us appreciate their value. But who exactly stands to gain the most from using them? Let's explore the various groups of people who can benefit from monitor light bars. 

Before choosing a monitor light bar, start with your actual lighting needs. The right choice depends not only on your monitor, but also on your room lighting, work habits, and how your environment changes throughout the day. If any of the following situations apply to you, a monitor lighting (monitor light bar or dual monitor desk lamp) may help improve your workspace lighting. 

If you often work at night or in a room with limited ambient light, a monitor light bar can add balanced lighting around your main work area.  
Look for a model that provides enough brightness and spreads light evenly.

If your desk is near a window, natural light may fall unevenly across your workspace and change throughout the day. A monitor light bar can help balance the lighting across your work area, while adjustable brightness, color temperature, or auto-dimming can adapt to changing conditions. 

If you often lean forward, sit back, or adjust your position, regular lamps may shine into your eyes or create uneven lighting. A monitor light bar with a controlled lighting angle helps keep light focused on your workspace.

Glare can come from light shining into your eyes, reflecting off the screen, or a bright monitor surrounded by a darker room. A well-designed monitor light bar helps direct light toward your workspace while keeping it away from the screen and your eyes.

By answering these questions first, you can better understand whether you need basic illumination, stronger glare control, auto-dimming, backlighting, or a model designed for a more complex setup.

Choosing the right ScreenBar starts with your setup. Answer the questions below to find the model that best fits your monitors, workspace, and lighting environment.

The number of monitors is the first decision point. Single-monitor and multi-monitor setups have different lighting coverage and installation needs.

Different monitor shapes require different mounting designs. Start by identifying your screen type to narrow down the models that can fit securely. 

After narrowing down the models based on your screen type, check whether the mounting clip fits your monitor. Measure the thickness at the top center of the screen, including any curved or protruding section on the back. 

The size of your main work area affects how much lighting coverage you need. A compact work area may only need focused lighting around the keyboard and nearby items, while a wider or deeper workspace may require broader, more even illumination. 

Your monitor placement affects how light works around your screen. If your monitor is placed against a wall, backlighting can help soften the contrast between a bright screen and darker surroundings. 

For dual or multi-monitor setups, ScreenBar Max is the primary recommendation. It uses a desk clamp rather than a monitor-mounted clip, so monitor shape and thickness do not affect compatibility. 

Use the questions below to confirm whether ScreenBar Max fits your desk setup.

Measure the distance from the desk surface to the top edge of your tallest monitor. ScreenBar Max extends upward from the desk, so the total height determines whether the lamp can be positioned above your screens.

ScreenBar Max can be installed with either a desk clamp or an optional desk base. Check your desk material and construction to determine which installation method is suitable.

The desk clamp on ScreenBar Max needs to fit around the edge of your desk. Most standard desks fall well within the compatible range, but thicker desks may need an additional accessory for a secure fit.

Before making your final choice, confirm that the ScreenBar Max fits your monitor or desk installation requirements. 

Still not sure how to choose the right one? Use the ScreenBar Finder or speak with a BenQ specialist to get a personalized recommendation based on your monitor and workspace.

Most monitor light bars are easy to set up, but the installation steps may vary depending on whether you use a single monitor light bar or a dual monitor desk lamp. 

① Mount it above your monitor 
Place the light bar on top of your monitor and make sure it sits securely and horizontally.

② Adjust the lighting angle 
Position the light so it illuminates your keyboard, documents, and main work area without shining into your eyes or reflecting on the screen.

③ Fine-tune brightness and color temperature 
Adjust the brightness and color temperature based on your room lighting, screen brightness, and time of day. 

① Align it with your main working position 
Place the lamp behind the area where you normally sit and work, so the light is centered on you and your main workspace rather than simply between the two monitors.

② Clamp and adjust 
Secure the lamp to the desk, then adjust its height and forward reach to fit your monitor setup. Make sure the lamp head stays parallel to the screens for balanced lighting across the workspace. 

③ Turn on and fine-tune 
Use front light for desk illumination and backlight to balance screen contrast, then adjust brightness and color temperature for your workspace.

A monitor light bar can improve your workspace by adding focused, comfortable lighting without taking up valuable desk space. But the best choice depends on more than brightness. It’s about your number of monitors, screen type, desk size, monitor placement, and lighting environment all affect which model fits best.

For single-monitor setups, choose a monitor light bar that fits your screen type and lighting needs. For dual-monitor workspaces, ScreenBar Max offers broader coverage for more complex layouts. For iMac users, iScreenBar is designed to fit the iMac workspace without disrupting its clean design.

By choosing based on your actual setup, you can create a workspace that is brighter, cleaner, and more comfortable for long hours of work, creation, gaming, or everyday screen use.
