Apple laptops conspicuously lack HDMI ports for easy TV connectivity, but that doesn't mean they're not capable of outputting an HDMI signal; they just lack a dongle. A Mini DisplayPort-to-HDMI adapter will do the trick, and many don't cost more than $10. In fact, the Mini DisplayPort to HDMI Female Adapter Cable by Portta only costs $5.50. PC users and those with extra monitors might also consider investing in a Mini DisplayPort-to-VGA adapter, also readily available. We'd say this has a narrow use case, but anyone with an older VGA monitor could find it essential.
