Before you do anything, read your TV’s manual, if you have it.
Here’s what to do:
Check your TV for a USB port.
They’re fairly common on modern flat screen televisions.
Don’t assume it’s going to be a standard rectangle USB.
Look at the port itself, and confirm you have a cord that fits.
Avoid plugging in USB hubs and other extension devices into your television’s USB ports.
It may not be able to support them and may cause other problems.
Consider getting a longer USB cord instead that will give you a little more access.
Press theSourcebutton on the TV remote, the side of the TV, or somewhere in the on-screen menu.
Change the source toUSB.
You should now see your phone’s screen on your television.
You’re probably going to need to fiddle with your phone a bit to match it one to one.
Why Connect a Phone to a TV With USB?
This is especially true of massively multiplayer games or video calls with several connections.
Even if your phone and television communicate with each other directly, there can still be problems.
All your phone and TV are really doing is communicating over a radio.
In some cases this is through your router.
If you have a cordless phone, for example, it may be scrambling your Wi-Fi.
If all that weren’t enough, you’ve got your battery to manage.
All this adds up to stutter, lag, buffering, and other annoying problems.
Plugging in a USB cable takes out a lot of this frustration.
Depending on the design of your television, it may provide power directly to your phone.
The solution to both is to get an adapter.
Places like Amazon.com carry USB-C to HDMI adapters if your phone uses a USB-C port.
If your TV doesn’t have HDMI ports, check for aMobile High-definition Link(MHL) port instead.
