What it means
Many gaming monitors have a 'wide gamut' panel that can show more colors than standard (sRGB) content was made for. Left unchecked that makes ordinary SDR games, the desktop, and video look oversaturated — neon reds, radioactive greens. An sRGB mode (also called sRGB clamp or emulation) reins the panel back to the sRGB range so those colors look the way they were meant to.
More detail
It is a color-accuracy setting, not a performance one — it changes how colors LOOK, never your frame rate or input lag. The trade is that while it is on you also give up that extra saturation for content actually built for a wider gamut (HDR, some color-managed apps), so it is not a blanket always-on. …
