Unbox the TV safely — do not lift it alone
~36sQuick Tip
Quick Tip: Keep the box and packaging for at least 30 days in case you need to return the TV. If you ever need to move, having the original box makes transport much safer.
Connect your cable box, streaming device, or antenna using HDMI
~40sQuick Tip
Quick Tip: Most TVs include one HDMI cable in the box. If yours did not, any standard HDMI cable from a hardware store works. You do not need an expensive brand.
Plug in the power cord and turn on the TV
~31sFollow the on-screen setup wizard
~26sQuick Tip
Quick Tip: Write down each answer you select so you can remember your choices if you need to redo the setup later.
Connect the TV to your home Wi-Fi network
~42sWarning
If your Wi-Fi password is not working, double-check that you are reading capital letters and numbers correctly from the router label. The number "0" and the letter "O" look similar — the password label on most routers uses a different font to tell them apart.
Sign in to your streaming services
~43sQuick Tip
Quick Tip: If typing on the TV remote feels slow, many streaming services let you activate the TV by entering a short code at their website on your phone instead of typing a full email and password. Look for a "Sign in with a code" or "Activate" option on the TV screen.
Adjust the picture and sound settings
~36sQuick Tip
Quick Tip: The picture and sound settings vary slightly by brand. If you cannot find them, search "[your TV brand] how to change picture mode" on Google — each brand posts its own instructions on YouTube and its support website.
Switch inputs to use your cable box or streaming stick

A new smart TV can feel overwhelming before you turn it on. There are cords to connect, apps to sign into, and a remote with what seems like too many buttons. This guide takes you through every step in plain language, starting with getting the TV out of the box and ending with watching your first show.
The encouraging news: every major smart TV brand — Samsung, LG, Sony, TCL, Roku TV, Amazon Fire TV — includes a setup wizard. When you first power on the TV, it walks you through each step with on-screen instructions. You do not need to memorize anything beforehand. This guide helps you understand what each step is asking so you are not surprised.
Choosing the right TV size before you buy
If you have not purchased your TV yet, here is a practical rule of thumb for sizing. Measure the distance (in feet) between your couch and where the TV will sit. Multiply that distance by 8. And you get the recommended screen size in inches. For example, if you sit 8 feet away, look for a TV around 55 to 65 inches. Sitting too close to a screen that is too large can cause eye strain. Sitting too far from one that is too small means straining to read text.
Most living rooms with a couch 8 to 10 feet from the wall do well with a 55-inch TV. A bedroom with a viewing distance of 5 to 6 feet is more comfortable with a 40 to 50-inch screen.
What "smart TV" means
A smart TV is a television that connects to the internet, the same way your phone does. Once connected, it can run apps — Netflix, Amazon Prime Video, YouTube, Hulu, Disney+, and many others — without a separate streaming device. Many smart TVs also come with apps pre-installed (you will see them on the home screen when the TV starts up).
If you also have a cable or satellite box, a streaming stick (like a Roku or Amazon Fire Stick), or a DVD player, you connect those devices through the HDMI ports on the back or side of the TV. HDMI is the standard rectangular connector that carries both video and audio through a single cord.
What you will need before starting
- Your Wi-Fi network name and password (check the label on your router — the box your internet provider gave you — if you are unsure)
- The email address and password for any streaming services you want to use (Netflix, Prime Video, etc.)
- A pen and paper to write things down as you go
- Someone to help lift the TV out of the box — modern TVs are thin and lighter than older models but can still be awkward to handle alone
After the initial setup
Take a few minutes to adjust the picture settings. Most TVs ship from the factory in "Vivid" or "Dynamic" mode — a very bright, blue-tinted setting designed to stand out in a store. In your home, this setting often looks harsh. Look for a picture mode called "Movie," "Cinema," or "Filmmaker Mode" and select it. This setting is calibrated to show colors as they were originally intended and is much easier on the eyes for long viewing sessions.
For sound, the built-in speakers on flat-screen TVs are often thin-sounding because there is not much space inside the slim frame for speakers. If voices sound muffled or hard to understand, look for a setting called "Speech Enhancement," "Clear Voice," or "Dialogue Boost" in the sound settings. Turning it on can make a noticeable difference without buying a soundbar.
