I have always wanted to try a portable OLED monitor because regular ones don't come in any smaller screen size than 27" (26.5" to be exact). Interestingly, numerous models with 13- or 14-inch displays have been available in the market for a while. Many of them boast 4K resolution, which is quite overkill at such a small screen size, but if you increase the screen size to 16 inches, things will be somewhat ideal. Lowering the resolution to 2K or 3K can also be a practical choice for many users, as it significantly reduces the overall hardware load.
A lot of OLED monitor listings on popular retailers like Amazon are from Uperfect, a brand that produces a variety of portable monitors. I have reviewed several portable monitors from the company, including its latest UMax 24, which is an incredibly large portable monitor, ideal for both gaming and work. This is my first portable OLED monitor sample from the company, which felt interesting due to its attractive specifications, such as 500 nits of brightness.
So, here I have it on my desk: a little display that comes with a dedicated adjustable stand. Uperfect advertises it as the first 16-inch 3K OLED portable monitor, but there is another such product from Newsoul; however, I don't know which company released their model first. Nonetheless, we will take a close look at the UColor O2's features, specifications, and evaluate whether it has what it takes to serve as an ideal portable display for gaming or productivity/work.
Packaging and Content
Uperfect sent me various accessories along with the monitor, including two monitor stands that one would need to buy separately. One is a dedicated VESA mount stand, and then there is this small adjustable VESA monitor mount for flexible layouts. The dedicated stand is what I would be using in this review, because it helps in using the monitor like a regular display. That said, here is the stuff you will find inside the actual UColor O2 monitor box.

- A protective cover
- USB power adapter
- Mini HDMI cable x1
- USB Type C cable x2

Technical Specifications
The UColor O2 doesn't bring any leading specifications, but I would say these are most practical for the masses. The 16-inch screen size is decently big, considering most remain in the 13-14-inch range, and the resolution is also less demanding. Still, with a resolution of 2880x1800 pixels, you are going to have a high pixel density, delivering detailed image quality, which is more than adequate for most users.
Color reproduction looks satisfactory on the paper, bringing a 100% DCI-P3 color coverage and an 8-bit + FRC color depth. While it's not going to be as smooth as a 10-bit OLED display, it will be hard for you to spot the differences in most cases. With 8-bit + FRC (Frame Rate Control) color depth, the monitor tries to achieve a 10-bit-equivalent quality, bringing smoother gradients and better HDR precision, which is acceptable.

Taking a Close Look
The O2 looks sleek and offers a metal-housing, which feels premium. It's very lightweight and thankfully, you get a protective magnetic cover to keep it safe from damage. The cover can be used as a support stand if you want to get the job done; however, I would recommend getting a dedicated one if you want more versatility. I would like Uperfect to also include a tutorial on how to convert the cover into a dedicated stand, since it was quite confusing.
The surface is glossy, and the side bezels are very thin. The monitor offers controls on one side and connectivity ports on the other. For connectivity, there is a single mini HDMI port and two Type-C USB ports. Uperfect didn't mention what version this HDMI is because it's crucial for achieving the advertised refresh rate. We will talk about that in the next section, but now let's move to the stand assembly.
I tried the dedicated VESA stand, which has a small base and a flexible arm to adjust the monitor. After getting it attached to the monitor, the O2 was able to stand without any noticeable wobble. The base isn't that heavy, which is kinda good for portability, but lightweight stand bases often bring poor sturdiness. Nonetheless, the stand was able to maintain stability as the monitor itself weighs quite low.
I loved how easy it was to adjust the display via this stand. It is tool-free, and the overall footprint on the desk is so small. Now, if you take a look at the back, you will find small speakers, one on each side. The other side brings a few buttons for customizations, and from here, you can access basic settings like Brightness, Contrast, HDR, RGB, and more.
Connectivity and Ease of Use
As I mentioned before, there are three connectivity ports you can use to connect the O2 to your devices. The USB Type C port will be ideal if you want to achieve the full 120 Hz refresh rate at 3K, but someone like me who wants to connect it to a GPU I have no other option than to use the mini HDMI cable.
Now the problem here is that after connecting it to my HDMI 2.1b on the Radeon RX 9060 XT, I could only get a 100 Hz refresh rate at 3K resolution. This is likely because the mini HDMI on the monitor is HDMI 2.0 and not 2.1, which cannot support 3K@120Hz. This was a bit disappointing, but Uperfect should clarify it in their specs.
Remember that you need to connect the monitor to the outlet using the USB power adapter if you are using the other USB-C or mini HDMI port for display. However, if your device can supply at least 15W of power via its USB-C port, you won't need the power adapter. Simply connect both the USB C/HDMI and the other USB-C to the device to power your device, and you are good to go.
Performance
Coming to its visuals and performance, I am definitely impressed by its deep contrast and high brightness, which is usually quite low on conventional OLED monitors. While the contrast is 100 times lower than that of traditional OLED monitors, I couldn't see any flaws in its contrast.
The blacks were super deep, and the monitor can retain a high brightness of up to 500 nits. It was quite bright in a well-lit room, even at 50% level. So, it appears to be perfect for gaming or work in bright environments, which is what you would want apart from excellent contrast. Out of the box, you get a good color vibrancy, and it's actually ideal for color-sensitive tasks as well.
O2 also brings HDR compatibility, but I wouldn't recommend turning on HDR via the monitor's OSD menu. It simply makes the colors extremely saturated, and it looks bad in that mode.
The image quality is also great. I wouldn't say it's anything top-of-the-line, but it's almost outstanding for any type of work. Considering that it offers a wide color gamut, a 1ms GtG low response time, and a 120Hz refresh rate, it isn't going to disappoint in any way. But there are surely some caveats, which, if Uperfect worked on, could make this the best 16-inch OLED monitor.
Apparently, the O2 monitor doesn't feature VRR or Variable Refresh Rate, which is a deal breaker for fast-paced gaming. Except that, it's top-notch, considering the response time is superior to conventional IPS portable monitors.
The Verdict
Uperfect UColor O2 does a great job in offering that incredibly rich and vivid image quality on a small 16-inch screen, while also ensuring a smoother experience via a high refresh rate. Its bright screen particularly makes it an ideal fit for most cases, and whether you want to play games or do some professional content creation, the O2 doesn't disappoint.
Only if the monitor could run at the advertised 120Hz refresh rate via HDMI connection and had VRR support, it would have been perfect for most. Nonetheless, even with a few caveats, the UColor O2 is a wonderful OLED portable monitor, which launched at nearly $500. For the same price, buyers could choose a budget 27-inch QHD OLED gaming monitor, but the O2 targets users who need maximum portability rather than screen size.
At the time of writing, the UColor O2 is available at just $329 on the official website, but users can also take a look at the Amazon listing.
