S3220DGF, Radeon R9 390, 165Hz?

Question

I have a new S3220DGF connected by the provided DP 1.2 cable to an older Sapphire Nitro R9 390 (11244-00-20G). I do not see any options other than 60Hz for screen refresh in the display adapter properties. Connecting with the HDMI cable had the same result. Both tests were with only one S3220DGF connected. Looking at the specifications for the R9 390, I do see it advertises 4k at 60Hz and Display Port version 1.2 which implies it should be capable of a similar bandwidth. Can you confirm if this setup should support 165Hz? And if so what steps are necessary to enable it?Thanks,

If both are enabled, you have done all that you can. Time to upgrade that 2015 video card. Dell tested on Alienware desktops AMD FreeSync 2 compatible video cards =
AMD Radeon RX 560X/570X/580X
AMD Radeon RX 5700XT
AMD Radeon RX Vega 64

Dell cannot confirm this because we did not test the 2019 S3220DGF on the 2015 AMD Radeon R9 390.

The S3220DGF maximums are =

2560x1440 60Hz with HDCP 2.2
2560x1440 165Hz (DP)
2560x1440 144Hz (HDMI)

To do any Hz higher than 60, you must turn FreeSync On in the S3220DGF Menu-Game and in the AMD Radeon settings.

* Right click on the desktop and select AMD Radeon Settings
* Navigate to the Display tab
* Set AMD FreeSync to On

Hi Chris,

FreeSync is enabled and the tooltip in the Radeon software displayed a range of 48-60 Hz.

Let me know if there is anything else I should try.

Also is there a list of tested video cards available?
