Thanks for replies. My monitor is DVI DL only. My old Haswell i5 4670 with HD4600 graphics was also single link DVI only (https://communities.intel.com/thread/44135), and it worked at 60Hz. Could somebody please explain why haswell can do it but raven can't ? Otherwise I find myself assuming that the hardware is capable of DL DVI, just that the manufacturers aren't validating for it, ergo fixable in software. I understand if AMD object to coding for something that hasn't been validated (I'd do the same myself). Would it be possible alternatively to provide hints in log output or code comments or on a wiki somewhere, such that people in my position can hack the source themselves ? Secondly, even accepting the single link limitation, shouldn't it be possible to run at 33 refresh rate ? I tried at 30 and got nothing. Thirdly, why does amdgpu refer to the connection as HDMI-A-3 ? There's no HDMI in the setup at all.
