The original PET monitor was a standard white monochrome picture tube. The exact shade of white depended on the manufacturer. Viewing pictures on a current color monitor is subject to all the effects caused by viewing an analog image on a digital monitor. Analog monochrome monitors have a continuos layer of phosphor. Digital color monitors have triplets of color, spaced regularly on the surface. A common effect is fringing (edges of letters come out as a different color because the width of letters are not integer multiples of the color triplets). Another effect causes the letters to be irregular in shape. This comes from the fact that the image must be scaled to fit a different resolution monitor. In the scaling process causes some lines of image are dropped because of rounding errors. On Thu, 19 May 2022, Rhialto wrote: > Do we know which colour the original (pre-green) PET monitors had?
