"I researched online that I can use DisplayPort MST to daisy chain multiple monitors.""I've also researched that the last link/monitor in the chain can be a regular HDMI monitor.""It's supposed to work." I do not see in the online U2913WM User's Guide  that DP MST daisy chain works with last monitor using an HDMI in port. It shows second monitor using DP in = [IMAGE]
I have Dell G15 5520 with RTX 3060 with USB-C/DisplayPort alt-mode output. I have Dell U2913WM with DP in and DP out ports. I have a generic HDMI only monitor. Before buying the Dell U2913WM monitor, I researched online that I can use DisplayPort MST to daisy chain multiple monitors. I verified that RTX 3060 has DisplayPort 1.4. I verified that the Dell monitor has DisplayPort 1.2 (yes, I've enabled it in monitor OSD). I've also researched that the last link/monitor in the chain can be a regular HDMI monitor. My connections are: This doesn't work. I get the signal on the Dell monitor, but nothing down the chain. I've turned on and off DP 1.2 support on the monitor multiple times. I've changed the down chain DP-HDMI cable. I've even reset monitor to factory settings. Nothing. What's wrong here? It's supposed to work.  I've got a random one off reply from someone elsewhere saying that some DP MST chains don't support HDMI as the last link, but it's not documented anywhere. I don't get it. Wouldn't output on DP out port work regardless if the output cable is DP-DP or DP-HDMI?
U2913WM, DP MST daisy chain to HDMI not working
