Mac not showing max resolution
Hi there, I have connected a couple of Dell U2715Hc to my MacBook via the Humanscale M-connect docking station arm which uses DisplayLink. I am unable to set the maximum resolution for these monitors when connected via the docking station. When I connect directly to the mac via the HDMI then I am able to see the maximum resolution. How can I overcome this? it's really not great with the fuzzy and not clear text and images. Thanks

The monitors maximum resolution is 2560 * 1440 but all I get is 2048 *1152 and everything looks blurry.

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.
You can find this information in the following document: https://apac.humanscale.com/userfile...016_INTENG.pdf But based on that information your docking station does not support your configuration. Best regards, Katarzyna

I have two monitors connected to the dock, one via the DP and another one via the HDMI. Are you saying that this would downscale? This wasn't the case on my other PC, I was able to choose max resolution.

Hello,
Based on the information that I have found, yes. Using two ports at the same time would cause downscaling. Just to make sure when you used another computer was it also macOS? Could you connect the dock to that computer again, make sure that you can select the needed resolution and collect logfiles there for us? Thank you, Katarzyna
