U4025QW, Mac Studio M3 Utra, 2560x1080
I just picked up the Dell U4025QW. As pictured in the screenshot, its default scale is 2560x1080. This was the case before and after installing drivers, required firmware, color manager, and main software package. I am using the provided TB4 cable that is connected to the Mac Studio TB5 port.
Additionally, the vertical BenQ EX3410R that's to the right has the ability to go to 144Hz refresh rate via HDMI, but it will not go above 100Hz.
Can anyone share any insight?

Dell Support must verify the ownership and warranty status. Click the blue "Get Help Now" on the right to start a private live chat session. Share the private U4025QW Service Tag with them.
* Verify that you are connecting to the U4025QW #6 TB4 upstream port (page 17)
* Are the two monitors in connected daisy chain? If yes, disconnect the BenQ EX3410R from the U4025QW. Connect the BenQ EX3410R directly to the Mac Studio
* Open the U4025QW Menu--> Display
* Open Thunderbolt Daisy Chain
* Select Standard
