I used to be able to change between 4k and 1080p on my Vizio P55-F1. I have an HDMI cable on HDMI 3. Recently updated driver to 20.11.2. I have Ryzen 3200g with Vega 8 Graphics.
When I display Adapter Properties for Display 1, it shows only one valid mode 4096X2160 True Color 32 Bit 30 Hertz. Why is only one Mode supported?
Why can't I do 1080p? Shouldn't that be easier to display?
