Is it possible, say, using a programming language like C or C++, to write a program that directly interacts with the power inverter or controller in a modern LCD monitor?
I’m told that it used to be possible to forcefully overclock the oscillator in a CRT to make it catch on fire. I’m curious as to whether the same principle can be applied to a modern monitor.
Being able to inflict real damage on a modern external monitor is highly unlikely.
Connections like VGA, DVI and HDMI don’t provide sufficiently direct access to the screen’s hardware.
The hardware design of a consumer product can be considered flawed if it allows a killer poke, i.e. destruction of a hardware component by issuing
software instructions.
In modern PC hardware, laptops have a tightly integrated display. It may be possible to write a program that has harmful effects on a laptop’s backlight,
e.g. by flicking it on and off rapidly by calling the ACPI interface.
