yast2 and 4K monitor

LS, When using an 4K monitor and yast2, I noticed that yast2 is using almost 3/4 of my screen with unreadable small characters. The only way to make it useful is to zoom in many times and to drag the window borders back. Is there a setting so that yast2: a - use normal sized windows, and b - to use characters sizes to have readable text. Regards, Frans. -- A: Yes, just like that A: Ja, net zo Q: Oh, Just like reading a book backwards Q: Oh, net als een boek achterstevoren lezen A: Because it upsets the natural flow of a story A: Omdat het de natuurlijke gang uit het verhaal haalt Q: Why is top-posting annoying?
