There are different types of LCDs, some have drivers and convertors already built-in and can receive serial data, others operate in on a parallel byte of data. Some operate on 5 volt TTL and others on 12 volt CMOS .

If you are talking about a laptop monitor, you can get software that can test for dead pixals.
