External monitor blurry after upgrading to macOS Ventura

I'm having difficulties configuring my BenQ PD2700U to display 1920x1080 HiDPI properly. It worked perfectly find before updating to Ventura.

I'm using it as an external monitor and it worked natively before upgrading to Ventura this morning. I've stumbled upon BetterDisplay as a solution that other people seem to be finding success with. But I'm having troubles making it work, too.

Has anyone managed to find a solution to make it work?

MacBook Pro 13″, macOS 13.2
