How to connect iphone to tv?

K so i wanna connect my iphone to my tv to watch videos from my iphone on there
anyways i was wondering how do i connect it to a dynex tv? (i have a dynex flatscreen its about 6months old) i noticed there's no USB spot there's only HDMI
how can i connect my iphone without a USB spot in my tv?

Use tape or staple might also work but only if staples are quite large

In order to connect your iPhone to your Dynex TV, you will need a component cable that connects from your iPhone to your TV component ports. These cables can be found relatively inexpensively online.

Do i absoulutely have to have a comeponent cable
