The fastest way: HDMI cable or USB-C adapter

The simplest connection is a wired one. Most Samsung tablets have a USB-C port on the bottom edge. If your TV has a USB-C input (less common), you can plug a USB-C cable directly in. More likely, your TV has an HDMI port, so you'll need a USB-C to HDMI adapter — a small dongle that costs $15 to $30 and converts the tablet's output to HDMI format.

Plug the adapter into your tablet's USB-C port, connect an HDMI cable from the adapter to your TV's HDMI port, then switch your TV to that HDMI input using the remote. The image appears on your TV within seconds. This method works when ready and requires no setup, pairing, or passwords.

If your tablet is older and has a micro-USB port instead of USB-C, you'll need a micro-USB to HDMI adapter instead. Check your tablet's charging port to know which one you have.

Key Takeaways

  • A USB-C to HDMI adapter is the fastest and most reliable way to connect most Samsung tablets to a TV, with no setup required.
  • Wireless casting through Samsung SmartThings or Google Cast works if your TV supports it, but requires both devices on the same Wi-Fi network.
  • Some Samsung tablets support Samsung DeX, which turns your tablet into a desktop-like interface when connected to a TV or monitor.
  • If your TV is very old and has no HDMI port, you may need a USB-C to VGA adapter instead, though this is rare.

Wireless casting with Google Cast or Samsung SmartThings

If you don't want to use a cable, you can cast your tablet's screen wirelessly to any TV that has built-in casting support. Most newer Samsung TVs, LG TVs, and TVs with Google TV or Android TV built in support this. The tablet and TV must be connected to the same Wi-Fi network.

On your Samsung tablet, swipe down from the top to open the quick settings panel, then look for a button labeled Cast, Screen Share, or SmartThings. Tap it, and your tablet will search for nearby devices. Select your TV from the list. The tablet's screen will appear on the TV within a few seconds.

If you don't see a Cast button, open the Google Home app (if installed) or Samsung SmartThings app and look for a cast icon there. The exact location varies by tablet model and Android version.

Using Samsung DeX for a desktop-like experience

Some Samsung tablets — particularly the Galaxy Tab S series — support Samsung DeX, a feature that transforms your tablet into a desktop-like interface when connected to a larger screen. When you plug your tablet into a TV via USB-C to HDMI adapter, DeX may set up automatically, showing a taskbar, resizable windows, and a mouse cursor (if you connect a wireless mouse or trackpad).

If DeX doesn't start automatically, go to Settings > Advanced Features > Samsung DeX and toggle it on. Not all Samsung tablets have this feature — it's most common on the Tab S9, Tab S8, and newer models. Check your tablet's manual or Samsung's website to confirm whether your model supports it.

DeX is useful if you want to use your tablet like a laptop, with multiple apps open at once and a keyboard and mouse. For straightforward screen mirroring, the HDMI adapter alone is usually enough.

Connecting to older TVs without HDMI

If your TV has no HDMI port — common in sets made before 2010 — you have limited options. The most practical is a USB-C to VGA adapter, which connects to the tablet and outputs to a VGA port (the blue port with three rows of holes). VGA only carries video, not audio, so you'd need to run audio separately through your TV's audio input or a separate speaker.

Alternatively, if your TV has composite video inputs (the red, white, and yellow ports), you could use a USB-C to composite adapter, though these are harder to find and less reliable. For very old TVs, a wired connection becomes impractical — in those cases, using a separate Bluetooth speaker and casting audio wirelessly while displaying video on a monitor or projector may be more realistic.

Troubleshooting a connection that won't work

If your tablet connects via HDMI adapter but the TV shows no picture, first check that you've selected the correct HDMI input on your TV. Use the TV remote to cycle through inputs until you see the tablet's screen. If the TV still shows nothing, try unplugging the adapter and plugging it back in, then restart your tablet.

If wireless casting isn't finding your TV, confirm that both devices are on the same Wi-Fi network — they must be connected to the same router. Restart both the tablet and TV, then try casting again. If your TV doesn't appear in the cast list, check whether it actually supports casting. Older TVs and budget models often don't have this feature built in.

If the image appears but is stretched or cut off, go to your TV's picture settings and look for an option called Aspect Ratio or Zoom. Set it to Fit to Screen or Normal rather than Full or Stretch.

What to buy: adapters and cables

For a wired connection, you need only two things: a USB-C to HDMI adapter (around $15–$30) and an HDMI cable (around $5–$15). Buy the adapter from a reputable seller — cheap adapters sometimes fail or produce a flickering image. Anker, Belkin, and Amazon Basics are reliable brands.

If you plan to use DeX or want to charge your tablet while it's connected to the TV, look for an adapter that supports Power Delivery — this lets you plug a power cable into the adapter while the tablet is connected, so the tablet charges while you use it. These cost a bit more but are worth it for regular use.

For wireless casting, you don't need to buy anything if your TV already supports it. If it doesn't, you can buy a separate casting device like a Google Chromecast ($30–$50) and plug it into your TV's HDMI port to add casting support.

Frequently Asked Questions

Do I need to install anything on my tablet to use an HDMI adapter?

No. Plug the adapter in and it works when ready. Your tablet recognizes the HDMI output automatically and sends the picture to the TV. No apps, drivers, or settings changes are needed.

Can I use my Samsung tablet to control the TV once it's connected?

Not through the HDMI connection itself. The cable only sends video and audio from the tablet to the TV — it doesn't let the tablet control the TV. You'll still need your TV remote to change channels or adjust volume. If you want remote control, you'd need a separate app for your specific TV brand, like Samsung SmartThings for Samsung TVs.

Will the tablet screen go black when I connect it to the TV?

No. When you plug in an HDMI adapter, the tablet continues to show its screen on the tablet itself while also sending the same image to the TV. You can see what you're doing on both screens at once.

What if my TV doesn't have any of these ports?

If your TV has no HDMI, VGA, or composite ports, it's likely a very old model. In that case, a wired connection isn't practical. Your best option is to use a separate display — a computer monitor with HDMI, a projector, or a portable display designed for tablets — rather than trying to connect to the TV itself.

Can I cast video from Netflix or YouTube to my TV this way?

Yes. Whether you use a wired HDMI connection or wireless casting, any video playing on your tablet will appear on the TV. Apps like Netflix and YouTube work normally — just play the video on your tablet and it shows on the TV screen.
