What is the difference when a spec of a monitor states
refresh rate 60hz

compared to something like stating horizonal and vertical, along with a "range"

Horizontal Refresh Rate
30 - 83 KHz

Vertical Refresh Rate
50 - 76 Hz

also, how do you know before buying a monitor, whether or not that monitor's refresh rate can be overclocked? and to how much?

They mostly all tend to support those ranges to be able to support the standard resolutions and refresh rates below 1080p60. That's about what you expect to find on a usual 1080p 60 Hz monitor. (off of memory, sorry; don't have the exact numbers memorized and am failing to find it in a very quick search)

Whether or not it can be run over nominal refresh rates and how much depends on the monitor electronics and a little bit on the graphics card and cable (before thing start breaking, potentially). You're not going to know from the specs. Ask people who have the monitor and guess / hope.

What's the difference between listing the range of horizontal and vertical vs just staying "refresh rate" as 60hz?
