Hi guys,

thought to ask, is it possible to upgrade a PC monitors firmware?

I heard its possible by some hackers to see everything on your screen if they flash a firmware that changes how your screen acts?

or is this a urban legend.

screen Im thinking of is a dell L1708 FP

they will need physical access to the screen's usb or hdmi port and the screen needs an affected processor..
