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....

The DPI and the polling rate button is on the bottom of all ZOWIE wireless mouse models.

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...

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....

Please follow the steps as follows:

1. When you are connecting via 4K enhanced receiver: (Please refer to the photo below and the user manual for more detailed information.

   a. Keep the mouse and the receiver aligned in the center for optimal performance.

   b. For optimal performance, use the mouse approximately 20 cm away from the receiver at an angle of 50 degrees (left and right). 

   c. Keep the receiver at least 50 cm away from other possible signal interference such as wireless routers....

Since monitors are passive devices, they receive the signal output from the graphics card without actively causing stuttering. However, several factors can affect monitor performance. Please follow these steps to troubleshoot:

1. Ensure cables are directly connected from your PC to the monitor. Avoid using
    splitters or adapters as they may cause latency or compatibility issues.

2. If you have multiple monitors, try disconnecting them temporarily. Multiple
    monitors can strain the GPU, leading to an unstable signal.

3. Reset your monitor through the menu: System > Reset > Reset All > YES.

4. Update your graphics card drivers to the latest version.

5. Ensure your PC is connected to a stable, low-latency network.

6. Close all background applications, including streaming apps, while gaming to
    check for any software overloading the PC and affecting performance.

7. Try lowering in-game video settings. Higher settings consume more CPU and
    GPU resources, potentially lowering FPS output.

If the issue persists after these steps, follow these additional checks:

1. Test the monitor with another PC if possible to determine if the issue is with the
    monitor or PC.

2. Connect a different monitor to the same PC to isolate the problem.

3. Adjust the scaling option in your graphics card control panel (e.g., NVIDIA
    Control Panel > Display > Adjust desktop size and position > Perform scaling
    on: GPU/Display; For AMD: AMD software > Gaming > Display > GPU Scaling
    > ON/OFF). This can sometimes affect performance.

If the problem continues, please contact our customer service team for further assistance.

For EC-CW series, U2:

To change click response time settings, please follow the steps below:

Wireless mode: power off the mouse first. Press and hold the shown button and power button on the mouse at the same time. 

Wired mode: power off and disconnect the mouse first. Press and hold the indicated button and re-connect the mouse at the same time.

• Fast response time: 4
• Normal response time: 5...

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, XL2540X+, 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.
