My computer monitor is 32 inches from my face here at home where I normally sit when using my computer. I prefer it to be about 10 inches further than that, but there is so much junk on my desk that if I push the computer back away from me, I will cause the tower of junk to topple onto the floor.
At work at the funeral home, where I use a computer a lot, the monitors are about 30 inches from my face. . I push them to the back edge of the desk for two reasons - 40 inches is a more comfortable viewing distance than 20 or 30 inches, and so that I have more room for papers and file folders on the desk between me and the computer.
For me, 19 inches would be a very uncomfortable and unnatural viewing distance. . But I realize that this is a personal choice that varies from one individual to another.
