S3220DGF, XFX R9 280x, 1440p 144Hz

Hello,

After countless hours of scanning many forums I am still unable to get my Dell S3220DGF to display 1440p 144Hz.

My system:

• AsRock Z97 Pro4
• i5-4690k
• XFX R9 280x

What I've done:

• Reset the monitor
• Updated to latest GPU and monitor drivers
• Tried several HDMI and 1.2 DP cables both of which supposed to run 1440p 144Hz (link)
• Disconnected secondary displays
• Tried different presets, including turning FreeSync on and off
• Unplugging and plugging the cable back in, restarting after making changes

My questions:

• From what I researched, my GPU should be able to output 1440p 144Hz, correct?
• My GPU does not support FreeSync, correct?
• What else can I try to make this work?
• Can the monitor be defective?

I am inclined to return the monitor despite liking it. My dilemma is whether I should consider keeping it even I can’t get this to work for a prospect of using its features when I upgrade my GPU in the future.

Any help will be greatly appreciated.

Thanks,
