If you own a Chromecast, you’re basically a wizard with a dongle. Plug it into the TV, open Google Chrome on your laptop, click the three dots (not the ones on your face), and select “Cast.” Suddenly, your browser tab is on the big screen.
But here’s the kicker: You can also cast your entire desktop. This is useful for when you want to show your mom a Facebook post but she can’t see your tiny laptop from her armchair. Just be careful what else is open. I once casted my desktop and accidentally revealed my search history for “how to remove chocolate stains from a cat.” My TV held no judgment, but my friends did.
Lag: The Great Enemy
Wireless has a dark side: lag. That’s the delay between you clicking and the TV reacting. It can be as short as a sneeze or as long as a family reunion. For movies, it’s fine. For gaming? You’ll be dead before your TV shows the bullet.
Fun fact: The average wireless delay is about 100 milliseconds—roughly the same time it takes for a hummingbird to blink. Gary, my imaginary hummingbird, thinks that’s too slow. Use a cable for gaming; your thumbs will thank you.
