144hz monitor but testing shows 60hz refresh rate

[doctorzoidberg]

Hello everyone!

I just picked myself up a QGeem usb-c dual monitor docking station and I am having an odd issue and I am wondering if this is expected behavior or if something isn't right.

Basically, I have a 1440p 144hz monitor and in windows I am able to select 144hz refresh rate for the monitor when connected through the dock (HDMI fro the dock to the monitor). The monitor itself shows it is a 144hz signal when I go into the setting but the rate and which the screen is being updated it is very clearly less than 144hz. If I go to one of the websites to test the refresh rate I am seeing it listed at 60hz. This is when connected to a dell XPS 15 7590.

However, if I connect my other laptop (an intel 16" Macbook Pro) I am able to select 144hz, the monitor shows 144hz and the image refresh likes its 144hz and the test also shows 144hz.

I had to install the displaylink drivers in order to get an image to show from my XPS 15, however the macbook pro also has those drivers installed and no picture showed until I gave it the displaylink app the screen recording permissions so I assume they are both being driven by the displaylink drivers and not native thunderbolt.

Is this a limitation of the windows implementation or could this be something with my particular laptop? I have a dell dock I am trying to replace for various reasons and that worked fine at 144hz with both laptops.

Any help and suggestions would be appreciated and I really like the dock otherwise.

Thank you!

Hello,

I know this is largely an abandoned post, but funnily enough I have the same problem but slightly inverted.

I got the Wavlink WL-UG75PD5-3H2D which has the newest DL7400 chipset during black friday this year.

I got it specifically because I wanted to make use of my 1440p 144hz Ultrawide monitor. When I connect my personal Surface Pro 11 with ARM to it, it works with my 1440p monitor at the intended and full 144hz range.

However, with M4 Pro MacBook Pro that I have for work, it reports that it's running the monitor at 144hz and the monitor also confirms that it's receiving a 144hz signal but going to testufo.com shows that the browser is only reporting 120hz but this is also false because the 120hz ufos and the 60hz ufos are showing the same refresh rate, so in reality the Mac only reporting 144hz but rendering only 60hz.

I have the latest 14.2 version of the drivers, and I know its not other issues like weird cables because the same exact setup works exactly as intended when using the Surface Pro 11.

Is there any way this can be troubleshot further? I'm pretty confident that basically a new Mac driver is needed to address the issue, but any assistance would be much appreciated. Thank you!
