Having owned a Dell S2721DGFA monitor for several months and being very satisfied with it, I decided to buy another one since I need a second monitor.

However, since I have only one DisplayPort output on my graphics card, I connected the new monitor through HDMI and now when I visit Nvidia Control Panel, I see this:

The display shown on the left is my older S2721DGF, connected via DP. Does the info shown in the image above mean that G-Sync isn't enabled over HDMI, or that it doesn't work with two monitors? Or it actually works but the above screen doesn't explain that because it doesn't say "G-Sync Compatible" on HDMI-connected monitor?
