FAQs

Please check the followings:

1. Press the monitor's OSD control keys or 5-way controller and check the Input
    options to see if DisplayPort is selectable. If DisplayPort is not selectable,
    please ensure the DisplayPort cable is properly connected to both devices.

2. If the DisplayPort option is selectable but no signal appears on the screen,
    unplug the cable and plug it back in to allow the monitor to re-detect the
    connection.

3. If the issue persists, try connecting the monitor using HDMI to confirm that
    the monitor functions correctly, then attempt the DisplayPort connection again.

4. Ensure you have updated to the latest graphics card driver and motherboard
    BIOS version. If you cannot update the driver while connected via DisplayPort
    due to no signal, switch connections to HDMI if possible.

5. If possible, test the monitor with multiple devices using DisplayPort and verify
    that at least one device shows a signal. Trying different DisplayPort cables and
    cross-testing the cable with other devices may also help.

6. If the problem occurs suddenly after normal DisplayPort usage, use HDMI to
    ensure that DisplayPort is set to a resolution and refresh rate supported by the
    monitor.

If none of the above steps resolve the issue, the monitor may need inspection. Please contact our customer service team for further assistance.

Monitors are passive devices and, therefore, require a graphics card to output compatible signals to enable Variable Refresh Rate (VRR) features. So the first step we would like to suggest is to check if your graphics card supports VRR technology (The name of VRR technology may vary from Adaptive-Sync, FreeSync to G-Sync).

For the Nvidia graphics card, please check it here

For AMD graphics card, please check it here

Second, check if your monitor features the VRR function.

Our models feature with VRR function below:

XL2730Z, XL2540, XL2546S, XL2731, XL2740, XL2746S, XL2540K, XL2540KE, XL2546K, XL2731K, XL2746K, XL2566K, XL2546X, XL2586X, XL2566X+, XL2546X+, XL2586X+.

How to enable FreeSync through graphics card settings

How to enable G-Sync via graphics card settings

On the monitor, please turn off DyAc / DyAc+ / DyAc 2  (if your monitor has that feature) through the monitor menu, since DyAc function is not compatible with variable fresh rate technology. Then, turn on the Adaptive-Sync/FreeSync Premium function through the monitor menu.

Please check the following steps:

A. Models with 144/165Hz:

1. For the newer models only with HDMI / DP port, please use a HDMI 1.4 / 2.0 cable or DP 1.2a cable that came with the monitor.
2. For the older models with DVI / DP port, please use a DVI-Dual Link cable or DP 1.2a that came with the monitor.
3. Make sure to update to the latest graphics card driver version.

B. Models with 240/280Hz:

1. Make sure to use an HDMI 2.0 or DP 1.2a cable.
2. If an HDMI 2.0 cable is used, make sure to connect to the correct HDMI 2.0 port.
3. If a DP 1.2a cable is used, make sure to use the one bundled by BenQ.
4. Make sure to update to the latest graphics card driver version.
5.  Make sure that your graphics card supports 240/280Hz.

C. Models with 360/400Hz:

1. Make sure to use a DP 1.4 cable that comes with the monitor.
2. Make sure to update to the latest graphics card driver version.
3. Make sure that your graphics card supports 360/400Hz.

D. Models with 540/600Hz:

1. Make sure to use the DP 1.4/HDMI 2.1 cable that came with the monitor.
2. Make sure to update to the latest graphics card driver version.
3. Make sure you are running Windows 11 and that it is up to date.   (Please note that Windows 10 has a limit of 500Hz.)
4. Make sure that your graphics card supports 540/600Hz.

• If you are running Win 10, follow this: Setting > System > Display > Advanced Display Settings > Display Adapter Properties. Then click the “Monitor” tab, choose your preferred resolution and refresh rate from the “Screen Refresh Rate” list, and click “OK.”
• If you are running Win 11, follow this: Setting > System > Display > Advanced Display > Display information >  Then choose your preferred refresh rate.

Or you can do the setting via the GPU control panel;

If it is NVIDIA GPU, please open the NVIDIA control panel, and then head to “Change Resolution” tab under the “Display” option, and then choose your preferred resolution under “PC (not Ultra HD, HD, SD)”, and choose your preferred refresh rate under “refresh rate” option.
