Monitors come in Interlaced and non-Interlaced types. The interlaced monitor fills the screen by first painting the odd lines and on a second pass painting the even lines. The Non-interlaced monitors fill the screen with one pass. The two most popular standards in use today are the Swedish MPR-II and TCO '92 standards and govern the radiation emissions of monitors. The TCO '92 standards is the stricter of the two.
Monitors can also come with picture tubes that are shorter than the average depth.
This makes them stand out less when placed up against a wall. Better monitors also provide anti-reflective surfaces to cut down glare. Power Management can also be provided making the monitor compatible with operating systems like windows which can put it in a mode which uses less power, put them in a stand-by mode or shut them off completely. And for universal compatibility, monitors can come equipped with power supplies capable of switching between different voltages. Holes in the plate are precisely aligned so that only the appropriate beam is allowed to hit the red, green or blue phosphor, a shadow mask absorbs electron energy, which is converted to heat.
