I have an Optiplex 5060 SFF unable to get 3840 x 2160 resolution.

• Windows 10 x64
• UHD Graphics 620 Driver for Windows, Intel-UHD-Graphics-Driver_V665C_WIN_27.20.100.9664_A08_02 loaded.
• HDMI male to HDMI male cable, DP male to DP male cable, DP male to HDMI female available.
• Monitor is a new UHD Samsung S32A70

With a right click on the screen, I am unable to get a choice higher than 1920x1080.

I have tried a 4K Displayport to HDMI adapter w/male to male HDMI cable and a straight Displayport to Displayport cable.

The HDMI cable w/adapter only gets the 1920x1080 option.

The straight Displayport/Displayport yields no video at all.
