How to Connect Your Samsung Tablet to a TV Using HDMI

The Direct Path: USB-C to HDMI Connection

Most Samsung tablets made in the last five years have a USB-C port that supports video output. You connect the tablet to the TV using a USB-C to HDMI adapter or cable — a single cable with USB-C on one end and HDMI on the other. Plug the USB-C end into your tablet's charging port, plug the HDMI end into any available HDMI port on your TV, and switch the TV to that HDMI input. The tablet screen appears on the TV within seconds.

The adapter itself costs between $15 and $40 depending on the brand. Look for one marked "USB-C to HDMI" or "USB-C video output" — not all USB-C cables carry video, so the listing should explicitly say it supports video or display output. Samsung's own adapter works reliably, but third-party options from Anker or Belkin perform equally well.

One important detail: some USB-C to HDMI adapters require power. If your adapter has a separate USB port or power input, connect it to a power source while in use. This is especially true if you are running video at 4K resolution. If the adapter has no separate power input, it draws power from the tablet itself, which is fine for standard HD video.

Key Takeaways

A USB-C to HDMI adapter or cable is the standard way to connect a Samsung tablet to a TV, and the connection is plug-and-play with no setup required.
Check that your tablet has a USB-C port — older Samsung tablets use Micro-USB, which requires a different adapter type.
Some adapters need their own power source for stable video output, particularly at 4K resolution.
The TV must be set to the correct HDMI input channel, which you select using the TV remote.
Wireless options like Miracast or Samsung SmartThings exist but work less reliably than a wired HDMI connection.

Checking Your Tablet's Port Type

Before buying an adapter, confirm which port your tablet has. Samsung tablets from 2019 onward use USB-C. If your tablet is older, it likely has Micro-USB, which requires a Micro-USB to HDMI adapter instead. Look at the charging port on the bottom or side of the tablet — USB-C is a small oval shape with no visible pins, while Micro-USB is rectangular with visible metal contacts inside.

You can also check the model number. Samsung Galaxy Tab S6 and newer models use USB-C. Galaxy Tab A models from 2019 onward use USB-C, but earlier Tab A models use Micro-USB. If you are unsure, search "[your tablet model] USB port type" online or check the specifications on Samsung's website.

Setting Up the TV Input

Once the HDMI cable is plugged in, your TV will not automatically switch to the tablet's video. You must manually select the HDMI input using your TV remote. Look for a button labeled "Input," "Source," or "HDMI" on the remote. Press it and a menu will appear showing all available inputs — HDMI 1, HDMI 2, HDMI 3, and so on. Select the input where you plugged in the cable.

If you are not sure which input you used, try each HDMI port one at a time. Most TVs have between two and four HDMI ports, usually on the back or side. Once you select the correct input, the tablet screen will display on the TV. The tablet itself will still show its normal interface — you are not mirroring or casting, you are extending the display.

Troubleshooting a Black Screen

If you plug in the cable and see nothing on the TV, first check that the TV is set to the correct HDMI input. Use the remote to cycle through each HDMI port. If the screen remains black after trying all inputs, unplug the cable from both devices, wait 10 seconds, and reconnect. This resets the connection and often resolves the issue.

If the screen is still black, the adapter itself may not support video output. Check the product listing or packaging — it should explicitly state "video output" or "display output." Some USB-C cables are charging-only and will not transmit video. If you bought a generic cable, try a branded adapter like Samsung, Anker, or Belkin instead.

Another common issue is insufficient power. If your adapter has a separate power input and you have not connected it, plug it into a USB power source. This is especially important if the video cuts out or flickers. Once power is connected, the image should stabilize.

Wireless Alternatives If HDMI Is Not Available

If your TV does not have an available HDMI port or you prefer not to use a cable, Samsung tablets support wireless casting through Miracast or Samsung SmartThings. Miracast is a built-in Android standard that works with most modern TVs. To use it, swipe down from the top of the tablet screen twice to open the quick settings menu, tap "Wireless Display" or "Cast," and select your TV from the list.

Samsung SmartThings is Samsung's own casting system and works only with Samsung TVs. If you have a Samsung TV, SmartThings is usually more stable than Miracast. Open SmartThings on the tablet, select your TV, and tap the cast icon. The connection takes a few seconds to establish.

Wireless casting is convenient but less reliable than HDMI. The video may lag, especially during fast motion or gaming. If you are watching video or playing games, HDMI is the better choice. Wireless works well for presentations, web browsing, or showing photos.

What Resolution and Refresh Rate You Get

A USB-C to HDMI adapter typically supports 1080p (Full HD) video at 60 Hz without any issues. If your adapter supports 4K, it will output 4K video if your TV supports it, but this requires a powered adapter and a high-quality cable. Most adapters in the $15 to $25 range handle 1080p reliably; 4K adapters cost $30 and up.

The refresh rate — how many times per second the image updates — is 60 Hz for standard adapters, which is smooth enough for video and everyday use. Gaming and fast-motion content will look fine at 60 Hz. If you need higher refresh rates for competitive gaming, you would need a specialized adapter, but these are rare and expensive for tablets.

Your TV will automatically detect the resolution the tablet is sending and display it. You do not need to adjust any settings on the tablet or TV — the connection handles it automatically.

Keeping the Tablet Powered During Long Sessions

When your tablet is connected to the TV via HDMI, it continues to charge if the adapter has a power input. If the adapter draws power from the tablet itself (no separate power input), the tablet will slowly drain its battery while in use, especially if the screen brightness is high or you are running demanding apps.

For sessions longer than an hour, connect the tablet to a power source using its charging cable. You can use the tablet's charger while the HDMI cable is connected — both the charging cable and HDMI cable can be plugged in at the same time. This keeps the battery from draining and ensures stable video output.

Frequently Asked Questions

Do I need a special adapter for newer Samsung tablets?

No. Any USB-C to HDMI adapter works with any Samsung tablet that has a USB-C port. You do not need a Samsung-branded adapter, though Samsung's own adapters are reliable. Anker, Belkin, and other third-party brands work equally well and often cost less.

Can I use a USB-C hub instead of a single adapter?

Yes. A USB-C hub with HDMI output works the same way as a dedicated adapter. Hubs are useful if you want to connect multiple devices at once — for example, a keyboard and an external drive while also outputting to the TV. Make sure the hub explicitly supports video output, as some hubs are charging-only.

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

No. The tablet screen stays on and shows the same content as the TV. You are not mirroring — the tablet and TV display the same image simultaneously. If you want to turn off the tablet screen to save battery, you can do that manually without affecting the TV output.

What if my TV is older and does not have HDMI?

Older TVs with only composite (red, white, yellow) or VGA inputs cannot be used with a USB-C to HDMI adapter. You would need a USB-C to composite or USB-C to VGA adapter, which are less common and less reliable. Wireless casting via Miracast is a better option for older TVs, though not all older TVs support it either.

Can I charge the tablet while it is connected to the TV?

Yes. Plug the tablet's charging cable into the tablet while the HDMI cable is also connected. Both cables can be plugged in at the same time without any conflict. This is recommended for long viewing sessions to prevent the battery from draining.
