I have 2 equals LG 27UD58 monitors which connected to Radeon RX 550:

  • The first connected via DisplayPort and have 10 bit color depts
  • The second connected via Hdmi and have only 8 bit color depts

For the second monitor no other color optyions available while first can be set up with 8 and 6 color depst. Why this happened? How to setup 10 bit color via HDMI for second monitor in windows 10?

Did you enable the “HDMI ULTRA HD Deep Color” option in the display’s OSD menu? – Daniel B – 2019-09-27T13:24:56.113

Try changing the pixel format first, as per manual. The display apparently does not support 4:4:4 with 10 bit over HDMI. – Daniel B – 2019-09-27T14:14:36.223
