I have a Dell U2415 connected to a NUC8 running Sierra, using an HDMI - HDMI cable and I’m getting 1920 x 1200 @ 60 Hz. I used to have it connected to a 2009 MBP running Snow Leopard using a mDP - HDMI cable and got 1920 x 1200 @ 60 Hz. Verified via the on screen display and About this Mac / Display Prefs.
My sister also has the U2415, connected to a 2015 MBP running High Sierra via an HDMI - HDMI cable and gets 1920 x 1200 @ 60 Hz.
Yet, the User Guide would seems to indicate that 1920 x 1080 would be the max for HDMI. A quick net search didn’t turn up any complaints about only getting 1920 x 1080 via HDMI.
So, I chose to believe the monitor & macOS rather than the User Guide.
