- CRT display is the most commonly used form of visual displays, through it is getting gradually replaced with LCD and Plasma displays. A computer monitor using CRT display. In a CRT, an electron beam sweeps the display screen horizontally, one line at a time, gradually down the screen. A synchronization (sync) signal brings the beam back to the top row of the display. This type of scanning (line-by-line) is known as raster scan.

Thread: how much power do projectors use? Amps = W / V Amps = 140 / 110 Amps = 1.2727 mA = Amps * 1000 mA = 1272 So, it you want to run for 5 hours, multiply 5 x 1272mA = 6360mAh (or to get back to amp hours divide by 1000 = 6.36Ah). Typically you deal in amps and amp hours, so it's simply 1.2727A x 5h = 6.36Ah.
