This is a hardware limitation. The hardware only has 2 PLLs for
non-DisplayPort monitors. As such, the driver only supports 2 independent
pixel clocks on non-DisplayPort monitors. If you have more than 2 non-DP
monitors, it will only work if several of them share the same pixel clock
(i.e., the monitors sharing a PLL have to display the same mode with the same
pixel clock). Older kernels did not properly warn about exceeding these
limitations.
