XPS 15 7590, USB Type-C to DP cable freezing, LCD flicker and tear
I recently got this 3440x1440 144 Hz monitor and this USB C to Displayport cable to go along with the monitor.
The USB C to Displayport (monitor) cable is not working at all. When I plug the cable in, the laptop sometimes does nothing or it just completely freezes (even after I remove the cable) causing me to force shutdown. I have tried a HDMI to HDMI cable which works fine but does not look good and the image is stretched out on the monitor.
My other laptop (HP EliteBook 840 G5 - 1080p ) connects fine using the USB C to Displayport cable and looks great.
Also if I connect and remove the HDMI or the USB C cable from the XPS, my screen tears extremely and flickers for a couple of seconds.
I can possibly try a USB C to HDMI cable but I would rather stick with USB C to Displayport because I was told that would give me the best possible performance.
Can someone people help me out with what's wrong? Should I try another cable? Should I try only Dell approved cables? Do I need a dock or something?
Note: I'm undervolting my laptop. I'm not sure if that is potentially making a difference or not.

Also, I can sometimes get the USB Type-C to DP cable to connect and the XPS will recognize it. I know this because in "display settings" I see the monitor shown as a second screen.
But when I try to change my monitor input mode to displayport, the monitor shows nothing for the XPS. The monitor recognizes the HP laptop though.

I was having the flickering issues previously and reverted back to the March 2020 video driver, which may have helped somewhat, but did NOT fix the BLACK SCREEN issue, which is well known. (4k 15")

On my XPS 15 7500, what I've found is that using a USB-C to DP cable with a 4K monitor, the display flickers if I plug the cable into either of the two Thunderbolt ports on the left side of the computer, but works just fine if I plug it into the USB-C port on the right side of the computer. This is precisely the opposite of what I expected, but there it is!

Just notifying all what the DELL-Cares agent did for the original poster. So in your own communication with DELL-Cares agent, you could reference what they did for the original poster.
