Question 1

Can you link two screw bars to one dial? I still use dual monitors.

Accepted Answer

YES, If you buy 2 units of ScreenBar Halo, both of them can use one wireless controller to control 2 light bars.
Both of light bars will use the same settings of wireless controller and can't set different settings individually.
For more information, please check as follows in ScreenBar Halo product page of Amazon US.

Pairing and Connecting Multiple ScreenBar Halos
You can pair and connect a wireless controller with multiple lamps to operate at the same time.
If the distance between the controller and these lights is within 1 meter, the settings of these lamps will change simultaneously.
1. Unplug the lamp.
2. Make sure that the power indicator is on (the wireless controller is activated), and the wireless controller is within 1 meter of the lamp.
3. While holding the Light Mode Switch button, tap and hold the My Favorite Mode button for about 5 seconds. You will see the function indicators on the wireless controller start flashing simultaneously.
4. After the indicators start flashing, cover the light sensor (on the reverse side of the light bar) of the lamp you wish to pair then plug in the USB power cord within 15 seconds. If the controller and the lamps are successfully paired and connected, all the indicators will turn off and the controller will go into sleep mode.

Question 2

Can you put a Logi webcam on top of the lightbar?

Accepted Answer

Webcam Accessory will be available soon in BenQ Store. 
However, some of the users have simply added webcam onto ScreenBar Halo without accessory. We recommend to try it first without accessory.

Question 3

Can front and rear lights be controlled independently? There are times I may only want the rear (ambient) light in operation.

Accepted Answer

ScreenBar Halo features three settings: front light, back light and both. You may adjust the brightness and color temperature in every setting. When both lights are on, they cannot be controlled independently.

Question 4

Can you connect one or more computers at the same time? I have a work computer and a gaming rig that I would love to get this hooked up to.

Accepted Answer

Hello there,

ScreenBar Halo is a USB-powered monitor light bar mounted on top of the monitor to light up the desk and to reduce the contrast between the brightness of the screen and the surrounding environment. Users can adjust brightness level and color temperature with the wireless controller that comes with the light. If you have a dual monitor setup, you can place the light on the monitor that you spend more time on, or simply change its position to the other monitor when needed. ScreenBar Halo guarantees a 500lux lighting coverage of 63 x 40 cm on your working area, which will be sufficient even for dual monitor users.

If you have any further questions, please contact us through the online chat on our official website. Our customer service team will be happy to assist you.
We hope you have a nice day.

Thank you.

Best regards,
BenQ Lighting
