Hello, Various HDMI versions enable higher and higher pixel clocks. However individual GPUs are not required to support the maximum pixel clock supported by the spec in order to be compliant. It appears that some GPUs max out at 225MHz while others at 297MHz (while others still, I assume, are limited to 165MHz, esp among the older ones).
We've been unable to find this in the VBIOS (I had a thought that it was in the table pointed to by the 'T' table, but we have a counterexample to that). Could you suggest a way to find this information either from the VBIOS or based on the GPU? Are there differences between regular HDMI and DP -> HDMI (passive)? This is becoming more and more relevant as 2560x1440/3840x2160 displays are become more common, while (dual-link) DVI-D is on its way out.
