Is it because the mainboard is not HDMI 2.0 or does not support DSC (Display Stream Compression?) (https://en.wikipedia.org/wiki/HDMI#Refresh_frequency_limits_for_standard_video https://en.wikipedia.org/wiki/HDMI#Refresh_frequency_limits_...). Raven Ridge supports 2.0, but it's down to the mainboard to also support that.
- phkahler 5y agoThat linked table indicates even 4k30fps (at 4:4:4) requires 6.18Gbps, while the motherboard page here: https://www.gigabyte.com/Motherboard/GA-AB350N-Gaming-WIFI-rev-10#kf https://www.gigabyte.com/Motherboard/GA-AB350N-Gaming-WIFI-r... Under the HDMI section indicates up to 5Gbps video bandwidth (in addition to 8 channel audio). So on the surface it sounds like I shouldn't even get 30fps, but I do. Thank you for the info, it looks like the board isn't up to the task via HDMI so I will make the effort to find a Displayport adapter. That PC has a LOT of life left in it and I'd like to get the most out of it ;-)
