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.

To check the battery power level, switch to  or  mode from the bottom of the mouse. Alternatively, charge the mouse. The power LED indicators on the mouse will light up and show the battery power level.

For 240Hz models, please check the following:

1. Make sure to use HDMI 2.0 or DP 1.2a cable.
2. If HDMI 2.0 cable is used, make sure to connect to the correct HDMI 2.0 port.
3. If DP1.2a cable is used, make sure to use the one bundled by ZOWIE.
4. Make sure to update to the latest graphic card driver version.
5. Make sure to check if the graphic card supports up to 240Hz.

For 360Hz models, please check the following:

1. Make sure to use DP 1.4 cable.
2. If DP 1.4 cable is used, make sure to use the one bundled by ZOWIE.
3. Make sure to update to the latest graphic card driver version.
4. Make sure to check if the graphic card supports up to 360Hz.

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 240Hz/360Hz 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 > Choose a refresh rate. Then choose your 240Hz/360Hz refresh rate.

Or you can do the setting via 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 Ulta HD, HD, SD)”, and choose “240Hz” / "360Hz" under “Refresh rate” option.

If it is AMD GPU, right click on your desktop and select “AMD Radeon Settings”, and then click on the “Display” option, and then you can choose your preferred resolution and 240Hz/360Hz under the Display options page.

To change the LOD settings for EC-A, FK, ZA,  EC-C, FK-C, ZA-C, S-C series, please follow the steps below:

Please disconnect the mouse first. Press and hold the following combination buttons together and re-connecting the mouse through USB.

• For a lower LOD: buttons 4 + 1

• For a medium LOD: buttons 5 + 1

• For a higher LOD: buttons 4 + 1 + 2

These cases happen in Valorant while players choose “Scaling by Display” in their graphics card control panel. Since the monitor is a passive device, it passively receives the signal output from a graphics card (which also needs to cooperate with the software). Compatibility issues from games and graphics might also cause the issue.

We have tested the other games like CS2 under the same resolutions, and refresh rate issues won’t happen. The good news is that we have some alternatives for you to solve this problem in Valorant. We suggest you can try the following steps:

1. Update your graphic card drivers to the last version.

2. Run your graphic card control panel applications:

# For NVIDIA's graphic card:

A. Select "Adjust desktop size and position" under the "Display" section on the left taskbar.

B. Select "Perform scaling on:" by "GPU"

*Note: you can select a scaling mode like Aspect ratio / Full-screen / No scaling to adjust.

There's a switch button to show the current DPI and Report rate.

• For wired mouse

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 240Hz.

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 360Hz.

D. Models with 540Hz:

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 540Hz.

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 144/165/240/360Hz 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 > Choose a refresh rate. Then choose your 144/165/240/360/540Hz 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 “144/165/240/360/540Hz” under “refresh rate” option.

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 the VRR function below:

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

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/DyAc+/DyAc 2 is not compatible with variable fresh rate technology. Then, turn on the Adaptive-Sync/FreeSync Premium function through the monitor menu.
