[SOLVED] Samsung 4k 60 Hz Monitor capping at 30Hz on Dell XPS 9370

[Rob Jones]

I recently purchased this monitor: https://www.amazon.com/Samsung-U32R...itor&qid=1577308497&smid=ATVPDKIKX0DER&sr=8-3 .
After I installed it and used it, I noticed that it was capped at 30 Hz (No option higher than 60 Hz was available in display settings). I read about similar problems online and no solution has worked so far. I'm using the cable that came with the monitor an HDMI cable (probably 2.0).
Something weird I noticed was that when I went into the Samsung monitor's settings and clicked information, the description had 30 Hz even though the monitor is 60 Hz, so I suspect the monitor wasn't set up correctly or some setting was wrong.

Please help me solve my problem. Thanks

60hz is only capable through HDMI 2.0 connection or display port connection.

What I mean is, even though your monitor has a 2.0 port, and the cable is 2.0 compliant, your PC HDMI out port may not be 2.0.

You're right. I just checked and my graphics card (UHD 620) can only go up to HDMI 1.4 or DP 1.2. To get 4k at 60Hz, an HDMI 2.0 or a DP 1.2 is required. Looks like I won't be able to use an HDMI cable but I'll try out a DP 1.2 and I'll see how that goes.

I got the DP 1.2 cable and 4k at 60 Hz works perfectly! Thanks for your help!
