S2721DGF, Xbox Series X, no 1440p 120Hz
I continue to attempt to set up my S2721DGF monitor which is capable of up to 165Hz. But, on my Xbox Series X trying to run 1440p 120Hz, it keeps informing me it's not capable of running that resolution at that frame rate. I don't under why this is the case, as this is a 165 Hz monitor? Any help would be greatly appreciated!

The S2721DGF is only 165Hz using its DisplayPort 1.4 port, not its HDMI 2.0 ports. The Xbox can only connect to the S2721DGF HDMI 2.0 in ports which when used on the tested Dell PC maxes to 2560x1440 144Hz.
As to why the Xbox Series X HDMI out port is not pushing 1440p 120Hz is unknown to Dell. Read through these threads.
