Many PC users have monitoring software installed, but what if there was a simpler, at-a-glance solution? Jonsbo has introduced the DS339, a USB mini-monitor designed for those who want to keep an eye on CPU and GPU usage, temperatures, and other system data without relying on in-game overlays or open Windows applications. It offers a straightforward and immediate view of your system’s performance.
This compact, elongated display features an IPS panel with a high resolution for its size. It comes with a stand, allowing for placement inside or outside your PC. While it might not be the ultimate feature-rich device, it’s an excellent addition for both showcasing your build and keeping everything under control simultaneously.
Jonsbo DS339: The Compact USB Monitor for In-PC Integration and System Oversight
The Jonsbo DS339 is incredibly easy to set up. Simply connect the display via USB, install the Jonsbo software, and use it as a customizable control panel. It’s not intended as a primary monitor for work or browsing but rather as an auxiliary display focused on monitoring, aesthetics, and personalization.
The DS339 boasts a 3.39-inch IPS screen with a resolution of 376 x 960 pixels, giving it a wide, panoramic format that fits well within a gaming PC case, on a visible part of the chassis, or even on your desk. It can also be positioned above the GPU, especially with vertical mounting solutions, to avoid stressing the graphics card.
Jonsbo states a brightness of 300 cd/m², which is ample for displaying metrics, graphs, clocks, or custom designs without needing a dedicated large screen. It’s bright enough to be seen without being overpowering, complementing your PC’s RGB lighting.
Compact Size, Easy Installation, Single Software for Visual PC Monitoring
Physically, the Jonsbo DS339 is a very compact accessory, measuring just 90 x 35 x 11 mm and weighing 58 g. Its ABS plastic body comes in black, designed to match modern PC cases, tempered glass builds, and systems where internal hardware is on display.
A key advantage is its versatile mounting system. The product images show the screen, a stand, an intermediate fixing piece, and screws. This allows it to function as a small desktop screen or be integrated into the PC’s interior, offering flexibility based on available space and aesthetic preferences.
Connectivity is via USB, with a maximum power consumption of 5V / 300mA, making it an energy-efficient accessory. Jonsbo guarantees compatibility with Windows 10 and later for its proprietary JONSBO-AIO Setup software, which includes a dedicated setup manual.
The most practical uses include displaying CPU and GPU load, CPU and GPU temperatures, the current time, activity bars, or custom designs. While it’s not a substitute for advanced diagnostic tools, it effectively centralizes essential system data, preventing it from being scattered across your main display.
The Jonsbo DS339 aligns with the current PC trend of not just building powerful systems but also showcasing their inner workings. Real-time monitoring on secondary displays has become a popular feature in recent years. Pricing for Europe and Spain has not yet been announced, so we will have to wait for further updates.
