External USB C Monitor not working
#28
I have an Accell USB-C to DisplayPort 1.4 Bidirectional Cable. Not a dock, it's a single-purpose cable that should use all 4 lanes. It's rated to 8K (7680x4320)@60Hz, 4K@120Hz, and 1080p@240Hz.

I'm attaching an Eizo Flexscan EV2730Q square monitor.

OS is the latest Manjaro update.

The monitor's native resolution is 1920x1920, and it can go to 2048x2048 as well. The odd thing is that 2048x2048 @ 59.4 Hz works, 1920x1920 @ 29.9 Hz works, but 1920x1920 @ 59.9 Hz just gives a black screen with "DisplayPort Signal Error". Flipping the connector over doesn't make any difference.

Any ideas? Hopefully it's a software problem and I can eventually use the monitor at its native resolution (which is sharper) at its full refresh rate.
