HDMI connections are becoming more popular with the release of various devices. Using HDMI connections can help make a nice presentation of photos, homemade videos and business/education projects. Most recent smartphones and tablets allow you to connect your device to a TV or monitor with an HDMI connection.
I also recommend purchasing HDMI cables from sites like eBay and Amazon. You will save money that way.
