Samsung monitor UJ590 using 4k shows “Display port” message on Inspirion 3530 every hour or so

Hi,

I got an Inspiron 3530 laptop for my daughter, but it doesn’t have DisplayPort Alt mode. I also got a D3100 docking station. I’m using a Lenovo monitor with UHD, and the other one is a Samsung Viewfinity UJ590 using 4k. I’m using HDMI for the Lenovo monitor and DP for the Samsung monitor. The Lenovo monitor works fine, but the Samsung monitor sometimes shows a display port message and then it disappears, like if the monitor lost connection.

Here are the specs for everything I’m using:

Inspiron 3530 black chassis
Samsung Viewfinity UJ590
D3100 docking station
Cable used: UGREEN 16K@60Hz 80Gbps DisplayPort Cable 2.1 DP https://a.co/d/03pIxHVQ

I’ve updated Windows and run Dell’s command update. Everything is up to date. I connected the docking station directly to the wall socket. Also, I believe the DP cable is backwards compatible.

Any help you can offer would be greatly appreciated.

Thanks,

Hey @Quincy479, Welcome to the Samsung Community! Sorry you’re running into some connectivity issues with your monitor but don’t worry, let’s try a few quick things that usually do the trick.

First, go ahead and turn off both the monitor and your PC. Unplug the DisplayPort cable from both ends and plug it back in firmly. If you’ve got another DisplayPort cable handy, it’s worth trying that too, especially a VESA‑Certified one. Next, open up the monitor’s menu, head to Settings → Input Source, turn Auto Source Switch off, and manually select DisplayPort. After that, double-check that your graphics drivers are up-to-date by grabbing the latest version from NVIDIA or AMD, then restart your PC.

If it’s still acting up after all that, please submit an error report using the link below, so we can take a closer look and help out:
