Hello,
I have a problem getting 60Hz on 4k resolution, looks like it's locked on 30Hz, if I switch to 2560x1440 the refresh rate is available in 60Hz but image is blurry.
I'm using:
MacBook Pro 16″, macOS 10.15

vs_cristian,
Since we currently only have the Mac to test with, try starting in safe mode to narrow it down: How to use safe mode on your Mac You can also try a new user as well: How to test an issue in another user account on your Mac
If you're still seeing the same thing after all those steps, you'll want to reach out to Apple Support directly: Get Support
Enjoy.
Unfortunately, nothing helped, I use the original HDMI cable from Samsung (HDMI 2.0) that comes with the monitor
and unfortunately I don’t have another one to test.
Also the monitor has a mini display-port which i didn't try yet, although the specification says that both ports support 3840x2160 60Hz
