Ubuntu 20.04/2070S/nvidia-460 sets one monitor into 2560x2922@30fps and does split screen mirror

Have a 2070 S connected to two Acer CB271HU 2560x1440 monitors via HDMI (one via HDMI port, another one via DP->HDMI adapter). When using a single monitor at native resolution, everything works fine with both outputs. When either monitor is running @ 1920x1080 and the other @ native, everything is fine. When both a running native resolution, the one connected via DP->HDMI adapter drops into weird 2560x2992@30fps mode and shows split screen, bottom being a mirror of the top.

This exact setup works perfectly in windows.

Bug report is attached. Couldn’t find any smoking guns but admittedly don’t know where to look.

The issue resolved itself by using different DP->HDMI adapter
