This shows that a desktop size of 3840x2160 pixels is being scaled to 5120x2880 (5K) over DisplayPort 1.4 with a 533.25 MHz pixel clock. So this looks normal, but the text on your monitor is probably fairly small because you've selected a "Scaling" option in System Preferences --> Displays that displays more text at the expense of that text being reduced in scale. Typically for a 27-inch monitor we'll set the effective desktop to 2560x1440 (which will scale to 5120x2880 for that clean "retina" look). This makes text more readable.
Can you post a screenshot of System Preferences --> Displays?

Thanks again. See the attached screenshot. So it looks like the display is actually driven by 5120x2880 (5K)? I got a MacBook Pro attached to a LG Ultrafine 5K and the picture looks a lot sharper. The Scaling is the same, but it looks sharper so I though the display on my hackintosh is not 5120x2880 but something below (as the "About this Mac->Display shows 3840x2160) and the display is scaling it up ...
