[SOLVED] BenQ XL2546 won't switch to 240Hz.

[AbbeLabben]

Hello,

I am running an I7 8700K and an RTX 2080 Super and I am using three monitors.
1x BenQ XL2411Z running 60Hz from my motherboard.
1x BenQ XL2411P running 144Hz from my graphics card.
1x BenQ XL2546 trying to run at 240Hz.

My issue is that whenever I go in to Nvidia graphic settings and set my refresh-rate to 240Hz it automatically switches back to 144Hz.

I have tried the following:

• Updating my drivers to the latest version.
• Unplugging my two other monitors.
• Using the original cable that came with the monitor, but now I am using a longer DP cable because the one that came with the box was too small. This one should be able to do 240Hz. It didn't work to get 240Hz with the default cable either.
• Changing the refresh rate from other locations on the computer.

Could I please get some help on this? Would be much appreciated!

EDIT: Solved, just plugged out and plugged in the cable a few times and now it's working fine again.

When running multiple displays, the video card will only run the lower of the two frequencies to both displays.

That isn't true.

That's totally wrong.

I just unplugged and plugged in the cable and then it worked! Even thought I did it before and now everything has been working perfectly fine for a few days. Solved!

Good! Plenty of people do have reported this issue, but so many of these threads never get resolved showing otherwise.

Glad you got it working. If you have trouble in the future, it may be worthwhile trying to install the monitor driver (if you haven't already). https://benqesupport.blob.core.wind... driver_MP_Windows 7_Windows 8_Windows 10.zip
