U2721DE, DP MST on disables Auto Option in Input Source
Hello,
When enabling the MST for Display Port in U2721DE monitor, then monitor is not able to Auto detect its input, and this option is also disabled from monitor's menu.
How can this be resolved? Is this a bug? I would like to be able to daisy chain by Display Port Out of U2721DE, but be able to Auto select by this monitor either USB-C or Display Port Inputs from 2 PCs.
Thanks.

By choosing to use DP MST on one PC, you are disabling the Auto Select features. To verify this assertion =
In your two PC setup, connect both U2721DE to different video card out ports. Then test the Auto Select features.
Example =
#1 PC video card out port USB-C --> #1 U2721DE USB-C
#1 PC video card out port DP --> #2 U2721DE DP
#2 PC video card out port DP --> #1 U2721DE DP
#2 PC video card out port HDMI --> #2 U2721DE HDMI

Hi,
I'm willing to not connect 4 cables, but use U2721DE to P2414H with DP, and connect U2721DE to #1PC with DP, and #2PC with USB-C.
I see that in U27U23QE this is possible - enabling MST does not disable Auto option. So how come in U2721DE this disables ?
Or does Auto feature is disabled in all Dell monitors, once MST is enabled ?
