Hello everyone,
There is a Mac mini late 2012 + Iiyama ProLite XUB2792QSU-B1 connected thunderbolt to the display port. Working resolution 2560x1440, everything works fine.
But the magnification of icons in the dock does not work. And there is a small problem with youtube, there is no video preview with the cursor.
Resetting the dock preferences didn't help. With an hdmi connection, everything is identical.
But if I connect Mac mini to a Panasonic tv via hdmi (1920x1080), everything works fine.
Installed Big Sur System 11.3.1 + OCLP(Catalina OS has the same problem). I'm using a Ugreen Thunderbolt 1/2 Mini DisplayPort to DisplayPort 1.2 cable.
Maybe someone knows what the problem might be? Searching the forum didn't help.

P.S. Sorry for my english.
