Do you need an HDMI 2.1 monitor?

Computer monitors that support HDMI 2.1, the latest HDMI standard, are beginning to trickle into online retailers. They sell at extremely high prices (when they're available at all). Even the most affordable HDMI 2.1 monitors, like the Gigabyte Aorus FI32U and Acer Nitro XV282K KV, are priced near $1,000. The high price of HDMI 2.1 implies it's important, but the truth is more nuanced. HDMI 2.1 brings new features to the table, but they're relevant only to people with specific needs.
