I wiew a pdf with lots of horizontal lines with a 1366x768 screen. Some lines have a 2-pixel width at every zoom value. The interline/line ratio is 12 if I zoom a lot. The result is good with a 1920x1200 screen. The result is good with Acrobat Reader. I attach a sample a of screen save . The pdf is made with MusiXTeX, a set of TeX macros.
Can I improve the viewing with the settings?
