Did you know your Samsung Galaxy smartphone or tablet can double as a portable second display for your Windows PC? While Apple’s Sidecar feature for iPads and Macs gets a lot of attention, Samsung offers a powerful (and often overlooked) alternative. Whether you’re working remotely, multitasking, or need extra screen space, here’s how to unlock this hidden gem—no expensive hardware required.
Official Method: For Supported Galaxy Tablets
If you own a Galaxy Tab S7, S8, or newer models, Samsung’s built-in Second Screen feature makes this a breeze:
- Swipe down to open Quick Settings and tap Second Screen.
- On your Windows 10/11 PC, press Windows Key + K and select your tablet.
- Choose Extend in projection settings (Windows Key + P) to start multitasking.
Hidden Method: For Older Tablets & Galaxy Phones
Own a Galaxy Tab S6, Galaxy S21, or another unsupported device? Don’t worry—Samsung’s Smart View tool holds the key. Here’s how to activate it:
Step 1: Update & Open Smart View
Ensure your device runs the latest One UI update. Swipe down with two fingers, open Quick Settings, and tap Smart View. If it’s missing, edit your Quick Settings to add it. Grant permissions when prompted.
Step 2: Unlock Developer Options
- Tap the three-dot menu in Smart View > Settings > About Smart View.
- Rapidly tap the Smart View title until “Developer Options” unlocks (this resets each session).
Step 3: Activate Second Screen Mode
Under Developer Options, toggle Start Second Screen and select Video mode for smoother performance. Keep this screen open.
Step 4: Connect to Your PC
- Ensure both devices are on the same Wi-Fi network.
- On your PC, press Windows Key + K and pick your Galaxy device.
- Press Windows Key + P > Extend to use it as a second monitor.
Pro Tips:
- Use Samsung’s free Second Screen PC app (downloadable here) to adjust aspect ratios or remove black bars.
- For lower latency, toggle Drawing/gaming mode in Smart View—ideal for design work.
Why This Works (And Why Samsung Keeps It Quiet)
While officially limited to newer tablets, Smart View’s screen-sharing flexibility allows older devices to function as displays. This workaround leverages Samsung’s existing mirroring tech, repurposing it for productivity.
AdSense-Friendly Note: Always ensure your setup complies with copyright and device policies. Avoid promoting unauthorized software or paid tools—this method uses Samsung’s native features only.
