I've got a Seiki 4k television I'd like to use with my m6800. I've been through several rounds of attempts to enable 3840x2160@30hz resolution but have thus far been unsuccessful. I've tried the following:
- Disable Switchable Graphics
- Manually update refresh rate to 30hz
- Directly connecting via HDMI
- Connecting from DisplayPort to HDMI via active adapter
Whenever I unplug the HDMI cable, I get a notification telling me that "An HDMI-to-DVI display connection has been detected" but the cable is HDMI on both ends. I get this notification using both the HDMI port directly as well as the DisplayPort -> HDMI with the adapter.
I've tried everything I can think of to get this machine to push out 4k but nothing has worked. Anyone have any thoughts or ideas? Anyone else had a similar problem and was able to troubleshoot it successfully? Thanks in advance for all of your help.
