> How come these things are not secured against at the LCD controller side? Because we make generic LCD controllers that can service a wide range of panels. Using generic parts with adjustable outputs is standard practice. It keeps prices down, keeps supply chains flowing, and makes it easier to design new systems around common parts. It also reduces the amount of waste because common parts can be re-used in new designs and resold if unused. Many things around you are controlled by software settings without separate hardware limits to keep them in check. If you have an enthusiast motherboard, you can reboot right now into the BIOS and set the CPU and RAM voltages to numbers that will fry your chips in short order if you want, and it won't stop you at the hardware level. Generic parts with a wide output range are great, but it requires care and attention to make sure the software is providing the right settings.
