eli5: how does vga, dvi,hdmi, displayport,usb control each pixel of a monitor if the cable doesn’t seem to have a wire for each and every pixel?
In: Technology
What we see as smooth animation on a monitor is typically the screen redrawing itself about 60 times per second. 1/60th of a second is enough time for modern electronics to send an entire screen’s worth of data pixel-by-pixel over a single pair of wires. One of the other wires on the connector is a “clock” signal whereby the computer tells the monitor the moment it’s about to send the data.
