Mac not showing max resolution

[KatarzynaCzaja]

Hello,

The logfiles confirmed that the monitors have the appropriate resolution available and that the resolution is automatically downscaled. I found that the docking station will support resolution 2560x1600 with single head but not with dual.
You can check that by testing resolution with just one monitor connected to DisplayPort and one to HDMI if it will do the same thing.

• Display Port: 2560x1600 single head, auto downscale to 1920x1080 with dual head. DP HDCP key not supported with external DP IC
• HDMI: 2560x1440 single head, auto downscale to 1920x1080 with dual head

You can find this information in the following document:

But based on that information your docking station does not support your configuration.

Best regards,
