Screen Mirror Galaxy S23 To TV: 5 Methods That Work (2026)
Your Galaxy S23 screen is not showing up on the TV, or you are not sure which way to connect it.
It is fixable, and Samsung gives the S23 several ways to do it, wireless and wired.
This guide covers five methods, the TV setting that most often blocks Smart View, and a fix table, and you can be mirrored in about five minutes.
Which screen mirroring method should you use?
| Method | What you need | Wireless | Best for |
|---|---|---|---|
| Smart View (Quick panel) | Same Wi-Fi, TV that supports Smart View or Miracast | Yes | Fastest start |
| Tap View | SmartThings 1.745 or higher, Samsung TV | Yes | One-tap start |
| SmartThings app | SmartThings app, same Wi-Fi | Yes | When the Quick panel tile fails |
| Google Home cast | Chromecast or other Google streaming device, Android 8.0+ | Yes | TVs with Google Cast |
| USB-C to HDMI cable | Adapter, HDMI cable, free HDMI port | No | No Wi-Fi dependence |
Menus can differ by carrier, phone model and software version, according to Samsung.
What should you check before you start?
Update the phone first at Settings > Software update > Download and install, as Samsung recommends.
- Same Wi-Fi: the phone and the TV must be on the same network for every wireless method.
- TV input: some TVs need you to switch inputs or turn on a screen mirroring option.
- Power saving: turn it off under Power mode before using Tap View.
Method 1: Mirror with Smart View from the Quick panel
- Swipe down from the top of the screen to open the Quick panel.
- Tap Smart View.
- Pick your TV from the list and enter the PIN if the TV shows one.
- Tap Start now on the prompt that asks about casting with Smart View.
To stop, tap the Smart View icon on the phone and choose Disconnect.
Allow Smart View on a Samsung TV first
If your Samsung TV never shows the connection request, a TV permission may be off.
Samsung lists the path as Settings > General > External Device Manager > Device Connect Manager > Access Notification.
The same setting is needed for Tap View, and TV menu names can vary by model year.
Method 2: Start with Tap View
- Open the SmartThings app and tap Menu (three lines), then Settings.
- Turn on Tap view, Tap sound.
- Hold the phone close to the TV and tap the phone presence detection notification.
Samsung says this needs SmartThings version 1.745 or higher.
Method 3: Use the SmartThings app
- Open SmartThings and select your TV.
- Tap More options (three dots), then Mirror Screen (Smart View).
- Tap Start now.
This is a good fallback when the Smart View tile in the Quick panel will not find the TV.
Method 4: Cast to a Chromecast or Google streaming device
Google no longer sells the Chromecast, so this method only applies if you already own one or a TV with Google Cast built in.
Google says your phone needs Android 8.0 or later and must be on the same Wi-Fi as the streaming device.
- Turn on microphone permission for Google Play Services.
- Open the Google Home app and tap Favorites or Devices.
- Touch and hold your device tile, then tap Cast.
- Choose Cast my screen, or pick Cast one app for a single app.
To stop, touch and hold the tile again and tap Stop mirroring.
Method 5: Connect with a USB-C to HDMI adapter
Samsung lists the Galaxy S23 series among the phones that support its USB-C to HDMI adapter.
- Plug the adapter into the phone’s USB-C port.
- Run an HDMI cable from the adapter to a free HDMI port on the TV.
- Switch the TV to that HDMI input.
- Tap the mirroring notification on the phone and follow the prompts.
Some models start mirroring on their own, and Samsung’s adapter page describes a DeX-style screen on the display in some setups.

Wired or wireless: what changes?
| Question | Wireless (Smart View, SmartThings) | Wired (USB-C to HDMI) |
|---|---|---|
| Needs same Wi-Fi? | Yes | No |
| Needs extra hardware? | No | Adapter and HDMI cable |
| TV setting to check | Access Notification on Samsung TVs | Switch to the right HDMI input |
| Samsung says it needs | Smart View or Miracast on both devices | A supported phone such as the S23 series |
Why is the picture small on the TV?
In Smart View, tap More options (three dots), then Settings, then Phone aspect ratio.
Choose Full screen on connected device, and turn on Remember settings to keep it.
Samsung notes that some apps may restart when you change this.
Why will Smart View not connect?
| Symptom | Try this |
|---|---|
| TV missing from the list | Check both devices are on the same Wi-Fi; touch and hold the Wi-Fi tile in the Quick panel to confirm |
| No prompt on the TV | Allow access on the TV when asked, and check Access Notification under Device Connect Manager |
| Connection drops or stutters | Smart View needs a stable Wi-Fi connection, so move closer to the router or use the HDMI cable |
| Tap View does nothing | Update SmartThings to 1.745 or higher and turn off power saving |
| Picture too small | Set Phone aspect ratio to Full screen on connected device |
| Still failing | Update TV software, then retry |
How do you update the TV software?
On a Samsung TV, go to Settings > Support > Software Update and choose Update Now.
Do not turn the TV off while it updates, as Samsung warns.
What if nothing works?
Samsung says both devices must support Smart View or Miracast, so an older TV may simply not qualify.
You can send an error report from the Samsung Members app or contact Samsung support.
As a last resort Samsung lists a factory data reset at Settings > General management > Reset > Factory data reset, which erases everything, so back up first.

Solid roundup of the three main routes. One clarification worth adding on Method 3: not every USB-C to HDMI adapter works with the S23 — it needs to support DisplayPort Alt Mode, and cheap passive adapters will just give you a black screen, so it’s worth checking that spec before buying. On the lag FAQ, I’d add that the ‘minimal lag’ answer really applies to video playback; for gaming or anything with precise input, the wired USB-C route is in a different league than Smart View or Chromecast. I run a small screen-mirroring guides site, net-mirror.pro, and this wired-vs-wireless question is the one readers ask about most. Also a nice touch noting there’s no cost to Smart View — a lot of people assume it needs a Samsung account or subscription, and it doesn’t.
