XL2540KE

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.

Since everyone is unique, and have different vision conditions and sensation on color and brightness. Thus, The cause of the discomfort to everyone may be very different. Even if the monitor has the same settings and displays the same image, some people may feel uncomfortable, while others may not. Following are a few tips, and we suggest you can try to adjust to alleviate the discomfort condition:

Sorry, you won’t be able to. This feature requires hardware, firmware, and software to work so only compatible models with the software can make use of this feature.

Please contact our RMA department through our website ( ZOWIE site > Support > Contact > RMA ) ; or you can send us a message on our global Facebook / Twitter @ZOWIE by BenQ

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.

That is Overdrive/Response Time Compensation (RTC) function in RL/XL series. This technology is based on applying an over-voltage to the liquid crystals to motivate them into their orientation faster. We will usually quote a "grey to grey" (G2G) response time figure on displays using this technology since they are normally the fastest transitions available.

On ZOWIE website, we didn’t show response time to XL2546S and XL2546K as well as all our XL & RL series.

There is always a trade off between overdriving the panel to make it faster which results in bad display quality. XL series fully leverage the panel fast response, but also considering an optimized setting for the overall experience. It is suggested that you can check other user's sharing on website, or test it by yourself in person which would be ideal.

All ZOWIE monitors are mercury free.

Please refer to the AMD website for details on differences between various FreeSync versions :

XL Setting to Share is proprietary ZOWIE software for select models that allows users to share their display color settings as a profile. This software also allows you to download compatible display settings from other users and save your settings "to go" on a USB drive.

XL Setting to Share can be downloaded from the following page as a full program and requires no installation. 

You can watch this video to learn more about how XL Setting to Share works.

This is a very common issue that usually occurs when any monitor is being used in a dark environment without secondary light source activated, the back-light and warmth of the monitor attracting the insects which get trapped inside the LCD layers.

Please refer to the Variable Refresh Rate (VRR) models listed below.

Sorry, the Display Pilot software has been phased out and we do not update it any longer.

Currently, only XL2540 & XL2740 are listed as G-Sync Compatible monitors.

For the latest G-Sync Compatible monitor list, please visit NVIDIA's website for the latest update.

 

But if your ZOWIE monitor has Adaptive-Sync / FreeSync Premium function, you can still enable the VRR feature with NVIDIA graphic cards.

Learn more about Variable Refresh Rate (FreeSync Premium / G-Sync Compatible / Adaptive-Sync):

This monitor has a VESA standard mount with 100mm pattern, allowing the installation of a wall mount or arm bracket. Please use M4x10mm screws and possible wall mount adapter accessory when doing the installation. Please check with the wall mount/arm kit vendor or check with ZOWIE RMA for further assistance if any.

All ZOWIE monitors support 100V~240V.

No, this monitor does not have a built-in speaker.

Please refer to the compatible model list below.

NVIDIA G-Sync Compatible works only via DisplayPort 1.2 or later version. 

AMD FreeSync Premium works with HDMI 2.0 and DisplayPort 1.2 or later version.

Models that support FreeSync (Premium) function should be G-Sync Compatible.Users may try the settings on the graphic card, but there will be no guarantee from BenQ.

Please check the following:

1. Power on your monitor, switch to the input source which you want to keep.

2. Go to 'Menu' in the OSD, select 'Save' >> 'Save Settings' >> 'Yes'.

3. Power off and on your monitor to see if the input source keeps.

This is normal behavior, much like making major changes to the graphics settings of a game. When FreeSync Premium is enabled or disabled with a game running, some games will be affected because graphics settings need to be reset for the change to take effect.

Solution

For 240Hz/280Hz models, please check the following:

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.
6. Install the monitor driver from ZOWIE official website. 
7. Please contact us (ZOWIE website: contact/RMA ) for further assistance if all you've tried all the above.

If the power LED is on or there is a beep sound:

Please refer to the following steps:

1. Unplug and reconnect the S Switch. Then, make sure it is connected to the monitor properly.
2. Reset the monitor by using "Reset All" in the "System" section of the main menu in the OSD.
3. Try to recreate the conditions that cause random colors when using an S Switch. If you are not sure what those conditions are, you can press the 1/2/3 buttons repeatedly to test functionality. 
4. If the problem persists, please contact us (ZOWIE website: contact/RMA ) for more assistance.

For new K series monitors, the way to save settings via the S Switch has been changed. If Gamer1 is selected, the customized display setting is only saved in the monitor.

It may happen when the user enables the FreeSync Premium function with some NVIDIA graphic cards (G-Sync enabled in the Nvidia control panel). It indicates the synchronizing between the monitor and graphic card.

Any custom resolution/Hz setting may damage your monitor due to out of the operation range different from what the monitor has been designed for, and it may make your monitor out of warranty accordingly.
