SW270c blurry connected to USB-C on Mac M1 Mini after upgrading to Sonoma

TL;DR - The SW270c display was sharper when at the full 2560 x 1440 resolution on Ventura than Sonoma.

Initially I observed that mac os is showing the "Default" resolution as 1920 x 1080 and the actual resolution selected was 2560 x 1440 (low resolution) after upgrading from Ventura to Sonoma. I manually changed the resolution to 2560 x 1440 but something about still seems slightly off. Less sharp than on the previous macos ventura.

Any thoughts or ideas? I've power cycled the monitor, rebooted my machine, disconnected reconnected cables.
