Samsung officially unveiled the Galaxy Z TriFold in South Korea on December 2, 2025, and it’s set to arrive in stores on December 12, 2025. It’s interesting, perhaps even a little surprising, to see how quickly Samsung is pushing foldable technology into more practical territory. One of the standout ideas this time is the way this tri-folding phone can work as a wireless external monitor for Windows PCs. For anyone who has ever struggled to find extra workspace while traveling, the concept feels oddly overdue.
Key Takeaways
- Samsung officially unveiled the Galaxy Z TriFold in South Korea on December 2, 2025, with a release date set for December 12, 2025.
- The device features a “Second Screen” mode that allows it to function as a wireless external monitor for Windows PCs using Miracast technology.
- Hardware specifications include a 10-inch Dynamic AMOLED 2X display, Snapdragon 8 Elite processor, and a 5,600mAh battery.
- Users can expand their desktop workspace on the go without carrying a dedicated portable monitor.
- Public discussions highlight interest in productivity benefits but raise concerns about the high price point and potential wireless latency.
The device includes a Second Screen mode that essentially turns its 10-inch display into an extended or mirrored desktop for Windows 10 and Windows 11. It’s not trying to replace a full monitor, but it does offer a lightweight alternative for professionals who tend to hop between workspaces and would rather not carry additional hardware. I think many people who work remotely might see this as one of those small conveniences that add up over time.
Samsung explains that it all works through Miracast support in both Windows and One UI. From the phone, users simply toggle Second Screen in the Quick Settings panel. On a Windows PC, pressing Windows Key + K brings up the Cast menu, where the Galaxy Z TriFold appears as an available wireless display. After pairing, the phone behaves pretty much like any standard external monitor. You can drag apps, documents, or even just a browser window over to the TriFold’s screen. It’s helpful for reference materials or keeping communication tools like Slack or Microsoft Teams visible without cluttering your main desktop. Everything is still controlled using the PC’s own keyboard and mouse, which makes the whole setup feel fairly seamless, at least in theory.
Of course, making something like this work smoothly requires capable hardware. Samsung built the TriFold around a 10-inch Dynamic AMOLED 2X panel with a resolution of 2160 x 1584 and a 120Hz adaptive refresh rate. That higher refresh rate should help movement look fluid, which matters more than people might expect when using it as a monitor. Inside, the Qualcomm Snapdragon 8 Elite processor and 16GB of RAM handle whatever background tasks the device needs to manage while acting as a display. Powering everything is a 5,600mAh battery divided across the three folding sections. Samsung notes that it’s the largest battery they’ve ever put in a foldable, which makes sense considering how demanding a bright, extended-use screen can be.
Public discussions on Reddit and X (formerly Twitter) show that people are intrigued but cautious. Some genuinely like the idea of having what they call a pocketable monitor. It could simplify business trips by removing the need to pack a separate tablet or portable screen. Still, a number of potential buyers hesitate when they see the price. At about 3.59 million won in South Korea, roughly $2,500 to $3,000 USD, it’s undeniably expensive. That price point has sparked questions about whether the convenience really outweighs what users could get by pairing a high-end laptop with a more traditional portable monitor.
Latency is another concern. Because the connection relies entirely on wireless transmission, some users anticipate a bit of delay compared to a wired setup. Comments suggest that while this isn’t a major issue for office tasks, coding, or reading documents, it probably won’t satisfy those who work on latency-sensitive activities like gaming or precise video editing. A few power users even mentioned they might lean toward third-party wired apps such as SuperDisplay if absolute responsiveness is critical.
Samsung plans to release the Galaxy Z TriFold in South Korea on December 12, 2025, with a broader global rollout expected in the first quarter of 2026. It will be interesting to see how people actually use this feature once the device is in their hands. Some may find it transforms their workflow, while others might decide the price or limitations aren’t quite worth it. But at the very least, it shows Samsung is still willing to explore ways a phone can become more than just a phone, even if the idea takes a bit of getting used to.
Frequently Asked Questions
Q. Does the Galaxy Z TriFold support wired monitor connections?
A. The native “Second Screen” feature uses Wi-Fi Direct (Miracast) for a wireless connection. Samsung has not advertised a native wired monitor mode for this specific feature, although third-party Android apps may offer this functionality via USB.
Q. Can I use the Galaxy Z TriFold as a monitor for a Mac?
A. The native Second Screen feature is designed specifically for Windows 10 and 11 integration. Mac users would typically need to use third-party software solutions to achieve similar functionality.
Q. Will using the phone as a monitor drain the battery quickly?
A. Yes, keeping the 10-inch screen on and receiving a wireless video signal consumes significant power. However, the device is equipped with a large 5,600mAh battery to help mitigate this drain.
Q. Is the latency low enough for gaming?
A. Most wireless display connections introduce some input lag. While fine for productivity tasks like reading documents or typing emails, it is generally not recommended for fast-paced gaming.
Q. What is the expected price of the Galaxy Z TriFold in the US?
A. While official US pricing is not yet confirmed, conversion rates from the Korean launch price suggest it will likely fall between $2,500 and $3,000.
Q. Does the keyboard and mouse work on the second screen?
A. Yes, when connected via the Second Screen feature, your Windows PC’s mouse and keyboard can move across to the Galaxy Z TriFold display and interact with windows there.
Is the crease visible when using it as a monitor?
The device has two hinges, creating two creases. While Samsung has improved the hinge design to minimize visibility, the creases may still be noticeable at certain angles or under specific lighting conditions.
