After my review of the large and powerful UPERFECT UMax 24, I was curious to see how the firm’s smaller option would perform. That’s where the UColor O2 enters – a 16-inch portable screen that delivers a serious combination of portability, durability, and rich visuals just right for travel, hybrid workstations, or simply expanding your screen space on the go.
Over the past month, I’ve used the UColor O2 extensively—testing it across various settings and scenarios. From casual gaming to remote work, this monitor has proven itself to be a surprisingly rugged and refined device that doesn’t skimp on features.
Built for Portability, Designed for Versatility
It includes all the essentials:
- The monitor itself
- A magnetic kickstand cover
- Two USB-C to USB-C cables
- A Mini HDMI to HDMI cable
- A power adapter
- Mounting screws
It’s also VESA-compatible, so you can mount it if you wish. The construction feels high-quality, and the controls are firm—an improvement over the slightly loose buttons on the UMax 24.
In spite of its thin build and light body (only 0.72 kg / 1.59 lbs), the UColor O2 is surprisingly rugged. Over a one-month test period, it was dropped on the floor several times and continued to function perfectly. That’s exactly what a portable monitor should be: rugged, light, and worry-free to take around.
Visual Performance That Shines
The UColor O2 is packed with amazing specs that exceed expectations for a monitor of its size:
- 16-inch OLED display
- 2880×1800 HDR resolution
- 120Hz refresh rate via USB-C (100Hz via HDMI)
- 1ms response time
- 500 nits max brightness
- 100,000:1 contrast ratio
- 100% DCI-P3 color gamut
- 16:10 aspect ratio
- 178° viewing angle
The OLED display provides stunning clarity and deep contrast, making games and videos look immersive and vibrant.
Integrated Options and Customization
The OSD menu allows for a good amount of tweaking, including:
- Brightness & contrast
- Sharpness & black level
- Hue, saturation & color temperature
- Blue light filtering (four settings)
- Eco modes and DCR settings
The OSD can be finicky, but quick-access buttons for brightness, volume, and input switching help streamline usability.
One limitation: the 1W built-in stereo speakers are serviceable, but lack punch. External audio is recommended for better sound.
No Built-In Battery, But That’s Not a Dealbreaker
The UColor O2 does not include a built-in battery, so it needs a direct power source. If battery power is essential, UPERFECT offers a separate model with that capability. However, for most scenarios—such as pairing it with a laptop, smartphone, or Steam Deck—the lack of battery is not a major issue.
Everyday Use and Final Thoughts
Even when stationary, the UColor O2 has become my secondary display of choice—ideal for break-time gaming, email checks, and streaming. Its magnetic stand cover makes it easy to set up anywhere, and it slides right into a backpack for travel.
Overall, the UColor O2 is a top-tier portable monitor that combines elegance, durability, and high-end performance. Whether you’re a gamer, a creative professional, or just need a reliable second screen, this monitor delivers excellent value.
