If you mean "large format display" (LFD) then I don't think you can convert. LFD are designed for 24/7 usage so they have higher quality components. Components with wider temperature range, bigger heat sinks, etc. They have different types of inputs/outputs. They may have DVI out to allow daisy-chaining displays. They have ethernet ports, but that is for remote configuration and control, not built-in apps. It is a very different target market. The TV market is very price sensitive, and the LFD market is more features and ruggedness.
