Predator XB271HK 4k Monitor stuck at 30hz.

Hi, my Acer Predator monitor is stuck at 30hz when running 4K. Im using Display Port 1.2 and have tried 2 different certified cables.

I only bought this monitor 4 days ago brand new.
I have a RTX 2080 Super and I'm pretty sure its capable of 4k 60hz...

I've tried the NVidia control panel and the windows display adaptor to change the refresh rate to 60, but only showing 30 and 24hz.
Is there anything else I can do, I can't change the max refresh rate on the monitors OSD settings unlike my 1440p 144hz monitor.

Model Name: Predator XB271HK
Part Number: UM.HX1EE.001

Please let me know if you require anymore info.

Kind Regards.

Can you provide the exact model of the notebook? Example g3-572-58vh. Also, are you using a 1.4 or 2.0 hdmi cable?

UM.HX1EE.001 - I believe that's the correct model number you're looking for.

I dont use HDMI as the monitor only supports HDMI 1.4. Therefore I have been using Display Port 1.2 and also 1.4.

Add this driver like this: https://global-download.acer.com/GDFiles/Driver/Monitor/Monitor_Acer_1.0_W7x86W7x64W8x86W8x64_A.zip?acerid=635841919116952996&Step1=MONITOR&Step2=PREDATOR&Step3=XB271HK&OS=ALL&LC=en&BC=ACER&SC=PA_6

Then check if the resolution is available!

Still the same, stuck at 30hz and I restarted the computer.

Does the same problem occur when connecting the display port cable?

Ziam_

Yeah, I have tried 3 different cables and all of the Display Ports on my graphics card. I have also tried to connect the monitor to the motherboard, but no signal.

Sorry, i think i misunderstood, its the same with the HDMI aswell. I cant even run 1080p 60hz. Im thinking a monitor hardware issue.

Does this monitor accept DP cable?

Ziam_

Yeah. 1 DP + 1 HDMI

Try uninstalling and deleting the driver for the intel and rtx2080 video card in the device manager and verify that when windows installs the standard driver, the 3840x2160 resolution with 60hz will appear. example:

Nope, didn't fix it.

I also tried to create a custom resolution in the NVidia Control Panel to set the refresh rate to 60hz, but then my screen goes blank and I have to unplug the DP cable.
