UStation Δ / Delta – Fold-out Monitor Reviewed by Teoh Yi Chie
These are the four new portable dual-stack monitors UPERFECT recently released:
- Ustation Delta 15.6 – Features 2x USB-C video, 2x mini-HDMI – 499 EUR
- Ustation Delta Lite 15.6 – Features 1x USB-C video, 1x mini-HDMI – 439 EUR
- Ustation Delta Max 18.5 – Features 2x USB-C video, 2x mini-HDMI – 549 EUR
- Ustation Delta Pro 18 – Features 2x USB-C video, 2x mini-HDMI – 799 EUR
Prices include free worldwide shipping and 2 years warranty.
The company had sent me the Uperfect Ustation Delta for review since I've reviewed several Uperfect displays in the past.
Conclusion: Dual display setups are great for productivity. Triple display setups are even better. The stacked design and built-in stand means this monitor doesn't take up much table space and you can store the display easily when needed. The quality of the two displays on my review unit appears to be different. One has brighter and more vibrant colors than the other. If you want the best visual experience, get the Ustation Delta Max with dual 18-inch displays with 2560 x 1600 resolution and 100% DCI-P3 color support. Mac users will need to install DisplayLink drivers.

The main difference is the type of video input. The better models have dual USB-C video and dual mini-HDMI ports. And the best model is of course the Uperfect Ustation Delta Pro with dual 18-inch displays with 2560 x 1600 resolution (16:10 aspect ratio) each and 100% DCI-P3 color support.

Design

This dual stacked design along with the built-in stand means this display or these two displays will not take up much table space. All ports are on the right side so if you're using a laptop, you have to position it in a way that the protruding cables don't get in the way.
Just looking at the dual 15.6-inch displays is a sight to behold. The dual 18-inch displays will be amazing.

Surprisingly, the front and back are not branded with UPERFECT. Build quality is solid as the casing is metal. Unfortunately, the matte textured metal surface is very prone to fingerprints.
The display weighs 1.55 kg, which is a bit heavy but not too heavy. The compact and foldable design makes it portable. You can easily store it on a shelf or in a drawer.

This is the folded stand and the 7.5 x 7.5 cm VESA mount on the back.
When the displays are folded, it's only slightly thicker than my Macbook Pro 14 with a case. If you get the 18-inch+ models, the overall size will be larger and of course heavier.

There are two mini-HDMI and two USB-C video ports, plus one USB-C port for power.
One USB-C video port can output video to two displays. However, if you use HDMI, you will need two HDMI ports.

These are the power and OSD buttons on the right side. They are grouped according to the top and bottom displays, just like the ports.

This display needs to be connected to power because it has to power two displays.
If you only use one USB-C cable to power the displays, several things can happen:
- Displays may flicker
- Displays may not reach maximum brightness
- You may only be able to power one, not both displays

According to the company, you need to install the DisplayLink driver for Windows and Mac for the two displays to work.
Below are some setups I tried and the results:
- Windows without drivers – With the included USB-C video cable, only one screen can be displayed
- Windows without drivers – With my USB 4 cable, two screens can be displayed
- Windows with drivers – With the included USB-C video cable, two screens can be displayed
- Mac without drivers – With the included USB-C video cable, only one screen can be displayed
- Mac with drivers – With the included USB-C video cable, two screens can be displayed
Since I no longer have the M1 Macbook Air, I can't say if three screens can be displayed, as M1 Macs are limited to only two screens. If I have to guess, I'd say it probably works, as the two-display limitation is actually a software limitation, not a hardware one – I've used four displays with M1 Macs before.

I used a Spyder5Pro color calibrator to calibrate the two displays, and for some reason, I couldn't calibrate the top one because the software always shows an error and quits.
For the bottom display, I measured 79% sRGB, 67% NTSC, 69% AdobeRGB, 68% P3, and a maximum brightness of 203 nits. However, I was able to measure the brightness of the top display, and it is 288 nits. The top display actually looks brighter and more vibrant compared to the bottom display. It's likely that the two displays are not the same, which is strange.

The surface has a matte texture and good anti-glare properties. There is a drop in brightness when viewed from the side. The display is not a touchscreen.
The resolution of each 15.6-inch display is 1080P, so there will be visible pixelation when working from an arm's length. On a 15.6-inch display, this resolution is still quite usable. If you need a higher resolution, Uperfect offers the Ustation Delta Pro for $799, which has two 18-inch displays, each with a resolution of 2560 x 1600.

The hinge is firm and can hold the displays at any angle. There are no visible cables connecting the top and bottom displays, so the cables are likely inside the hinge.

This is the lowest angle for the stand. Personally, I prefer both displays to be at the same angle.
The display sits quite low on the table, just like a laptop display. To raise the display, you'll probably need a laptop stand or a VESA arm mount.

The display and color settings you can adjust via the OSD are brightness, contrast, sharpness, and color temperature. There are also various gaming settings, which I did not test. There is HDR support, but it's not true HDR.

This triple display setup is great. Since there are three displays, you can have three workspaces. You can use the WinKey + arrow keys shortcut to easily move windows to different displays. If you're using macOS, you'll need to install the Rectangle app to do the same.
By the way, the two 18-inch displays are almost as big as a 27-inch 16:9 monitor, and that means a lot of extra desktop space.

There are two rubber feet on one side that allow the displays to be set up vertically. Since there's no auto-rotation, you'll have to change the desktop orientation in your operating system settings. This setup is good for viewing vertical content, such as web pages.
So why not buy a desktop display or a traditional monitor with a matching stand? There are three reasons:
- It's easier to set up three workspaces this way
- Thanks to the foldable design, you can store the display easily and quickly
- The design is portable
- The design doesn't take up much desk space
Conclusion
A dual display setup is always useful. That's a fact, not even an opinion. The only thing more useful is a triple display setup.
This is one of those products where you immediately realize how useful it is when you use it.
