On the top menu is an open titled "Tutorials"

For things like screens, that's hardware. Look under the hardware tab.

There are two different items that both can be referred to as LCD displays.

Small 2x8 style LCD displays, usually I2C or Serial (like the first of your links)
LCD displays such as monitors, tvs etc. (like the second link)

They both work differently. Typically the second type need a video input through VGA or composite (or possibly HDMI these days?). The EZB cannot output anything to this type of screen.

There are the smaller LCD displays which are Serial or I2C, I've yet to source a serial one to fit my current project but I2C are all over eBay. Be wary of which one you get and search on here first as the one I bought was useless as it had no decent documentation.

You can use either Serial (3 wire, connects to Digital Port) or I2C (4 wire, connects to I2C Bus). I2C is more complicated than Serial, at least to me it is...
