Title: Polaris, Freesync over HDMI with open driver?

Hi, I have an "urgent" question, I think I'll finally buy a monitor as said in another post, and I would like to understand what is the state of the Freesync with the open driver for Polaris card (RX 480, 4 or 8GB?) that I think I'll try to buy the next days.
The AMD site reports that the Freesync works on Linux only on the DP but it is unclear if it is about the open driver or not or in general.
The monitor I'm choosing, Dell S2418H, has only the HDMI port and I would like to try the Freesync.

I recommend avoiding HDMI. If monitor doesn't have Display Port - don't buy it. Freesync support will probably come to upstream kernel in 4.15.

Thank you.

Ok, I know that is still not upstream but there is a way to already install it, I hoped someone have tried on Polaris and can say something.

Is the DP so important? Why? Because the monitor is just a FHD so maybe HDMI is ok for everything or do I miss something?

Yes, DP is important. HDMI is inferior in many ways. Plus currently Freesync simply requires Display Port to work.

Ok, thank you, I'm now looking for a monitor with a DP. I had to change it anyway because that Dell is glossy...
