A full pixel defect is a bright white dot or very noticeable black dot on the display. No full pixel defects are allowed per HyperX monitor specification.

A sub-pixel defect is also referred to as a dot defect.

Bright dot sub-pixel defects are permanently "on", displaying a colored red, green, or blue spot on the display at all times.

Dark dot sub-pixel defects are permanently "off", displaying a black dot on the display at all times.

A different type of defect caused by microscopic contaminants within the manufacturing process can also be found. Contamination results in a dark "stain" covering one or several sub-pixels. They are not pixel or sub-pixel defects per say. No contamination is allowed under HyperX policy.

	Dark sub-pixel defect - In this image, a dark spot on a white background results from a green sub-pixel, which is in the "off" or dark state.
	Bright sub-pixel defect - In this image, a bright spot on a black background is caused by sub-pixels (in this case, a red sub-pixel) in the "on" state.
	Debris trapped within the LCD structure can result in dark spots, but under magnification these are distinguished from an "off" sub-pixel, as the shape of the contaminating particle is visible.
