The LCD Expert application is used to operate an LCD display that communicates with the computer via the LPT port. This type of display connected to the computer can display a number of useful information, including system information (time, date, information about hard drives, processor, etc.), RSS feeds, spectrum from Winamp, current weather, point changes in stock indices, exchange rates, IP number and many more. The distinguishing feature of LCD Expert from foreign programs is the ability to display Polish diacritical marks.
