Identify your Mac device and BenQ monitor model ID and specs

1. Find your “Mac version” first: choose Apple menu > About this Mac > Overview

2. Use your verified Mac version and look for available ports from the “Charging and Expansion” section via https://support.apple.com/specs

3. Look at the back of your BenQ monitor and find “model ID” on the label at the lower side of the rear panel.

4. Check the product page “buy” and “specs” sections of the specific “BenQ model ID” you are looking for to get an overview of available connectivity ports. https://www.benq.com/en-us/monitor.html

Ensure the right cables are used to connect your Mac and monitor

1. Locate the right ports on your monitor and use the correct cables to connect your Mac device.

2. Connect a Thunderbolt/USB-C display: connect the display to a Thunderbolt/USB-C port on your MacBook Pro, MacBook Air^®, iMac^®, Mac mini^®, Mac Pro^®, or Mac Studio™. We strongly suggest using this method to get the best performance.

3. Or connect a DisplayPort (DP) display: use a USB-C to Display Port 1.4 cable to connect the display to a Thunderbolt port on your MacBook Pro, MacBook Air^®, iMac^®, Mac Mini^®, Mac Pro^®, or Mac Studio™.

4. Or connect an HDMI display: plug a cable from your monitor’s HDMI in port directly into the HDMI out port on your MacBook Pro, MacBook Air^®, iMac^®, Mac mini^®, Mac Pro^®, or Mac Studio^™.

Use an Apple USB-C Digital AV Multiport Adapter to connect the HDMI display to a Thunderbolt / USB4 port on your Mac computer.

5. Or connect a VGA display: use a USB-C VGA Multiport Adapter to connect the display to a Thunderbolt port on your MacBook Pro or iMac^®.

*Monitors with Thunderbolt 3/USB-C also work seamlessly with Mac devices that feature Thunderbolt 4.

*Please note that MacBook Air and MacBook Pro USB-C cables may sometimes support power delivery only, depending on cable specifications. To connect the display, you need to use the USB-C/Thunderbolt 4 cables BenQ offers or purchase an Apple Thunderbolt cable at the Apple Store.

Enable a signal on the monitor

If you encounter “no signal detected” or “no cable connected”, try the following steps:

1. Turn your monitor off and on

2. Change input source: open your monitor’s OSD (on-screen display) by using its physical controls (either a joystick or a series of buttons) and navigate to Input Settings and select the correct input source option.

3. Check whether your cables are connected properly. Make sure the display cable is plugged into the correct port on your Mac and securely seated in the port.

4. If possible, try using a different type of cable to test. So, if you’ve been using DisplayPort, try using an HDMI cable instead.

5. Please use the cable BenQ provides in the monitor box rather than 3^rd party cables or a docking station.

6. If none of the above steps resolve the issue, the monitor needs to be serviced. Please contact our customer service team, as we'd like to offer additional assistance.

Mirror or extend your Mac display

Mirror: want to design your artwork on your MacBook Pro, but on a larger display with full sized Dock icons? You should “mirror” your Mac display to the external monitor.

1. Choose Apple menu > System Settings, then click Displays in the sidebar (you may need to scroll down).

2. Click Arrangement, then hold Option while dragging items on top of each other.

Extend: to get a larger workspace, you can set your external display to work side by side with your Mac computer to create one large, continuous desktop.

1. Choose Apple menu > System Settings, then click Displays in the sidebar (you may need to scroll down).

2. Click the name of your display on the right, then click the “Use as” pop-up menu, and choose “Extended display” or Stop Mirroring.

Select your preferred user interface and desktop scaling

By default, your Mac uses what the operating system considers the optimal resolution for your display size. The scaling chosen affects the size of text and icons as shown on your screen. In most cases we recommend using the resolution and scaling that Mac OS automatically sets for you. However, you may manually change resolutions to make text and other visual elements increase or decrease in visible size. This may prove beneficial, depending on your preferences.

1. On your Mac, choose Apple menu > System Settings, then click Displays in the sidebar (you may need to scroll down).

2. Select your desired user interface (UI) size.

Can I adjust the color mode on my BenQ monitor?

On your Mac device, disable HDR mode first, then adjust the color mode based on your workflow preference.

How to adjust M-book mode

Go to Color > Color Mode > M-book
