We've recently encountered a number of questions pertaining to the maximum display frequency supported by HDMI, primarily with readers wondering if 1080p / 120Hz will work through HDMI. This has been in pursuit of some of our monitor content, including our monitor overclocking guide (which advises against HDMI).
The market's domineering display interfaces are DisplayPort, HDMI, and (still) DVI; for high-frequency output, DVI dual-link and DisplayPort are almost always used and recommended.
