I’ve been using this dual-screen portable monitor for months and now I won’t leave home without it

The UPERFECT Delta is a dual-screen portable monitor that folds up like a laptop to protect both of its 15.6-inch, FHD displays when in transit. There’s a built-in kickstand, rubber feet on the sides and bottom to hold it in place as well as VESA mounting holes so you can add it to your desk setup. 

At just under four pounds, the UPERFECT Delta weighs about as much as one of the best laptops. When closed, it’s only half an inch thick. It’s easy to slip into a backpack and its folding design means you won’t have to worry about a case. A single USB-C cable can power and drive both displays simultaneously when connected to a laptop,, but there are also two mini HDMI ports for your other devices. You can use the screens independently with two devices at the same time or even fold the UPERFECT Delta in half if you want to share a screen with a friend or coworker. 

You are paying a premium for the UPERFECT Delta compared to purchasing two portable monitors separately. However, the convenience is worth the added cost for those that want a portable multi-monitor setup powered by a single cable. Our UPERFECT Delta review will help you decide if this is the ultimate accessory for working from anywhere.

UPERFECT Delta: Specs

UPERFECT Delta: The ups

The UPERFECT Delta isn’t your typical portable monitor, nor is it a laptop screen extender you have to put together and then attach to your laptop. Instead, it's two portable monitors in one device that can be set up and packed away in seconds. The foldable 360 degree hinge also lets you use the UPEFECT Delta in some ways you might not have expected.

One cable connection

There are two USB-C ports and two mini HDMI ports on the UPERFECT Delta’s left side. While the USB-C port on the very bottom is just for powering the device, the one above it can display video from your laptop or even one of the best mini PCs using a single USB-C cable.

Depending on your laptop, you may need to plug in the UPERFECT Delta to the wall to use both screens simultaneously. However, I was able to easily use both screens simultaneously without external power with my ThinkPad laptop and with both the AceMagic F2A and AtomMan G7 PT mini PCs. I tried doing this with the Lenovo Chromebook Duet 3, but video only appeared on one of the UPERFECT Delta’s displays, likely due to the limitations of ChromeOS. 

It’s also worth noting that you may need to download a driver to use both screens simultaneously. Based on some of the reviews I’ve read online, you will need to do so if you plan on using the UPERFECT Delta with one of the best MacBooks.

Share a screen

Although you can use both the UPERFECT Delta’s 15.6-inch screens simultaneously on one device, you can also use them separately with two devices. For instance, you can play games on one by connecting a console to the device and work on the other from your computer. Likewise, you could run Windows 11 on the bottom and macOS on the top if you need to use multiple operating systems for work. 

Thanks to the UPERFECT Delta’s 360° hinge, you can also fold this dual-screen portable monitor all the way around like one of the best 2-in-1 laptops. This way, you can have an extra screen connected to your laptop and a coworker, or a friend can do the same with their laptop since not everyone wants to lug around a portable monitor. This can also be useful for when you want to give a presentation or show something to someone else on your laptop without having them standing over your shoulder. 

Not just for traveling

Portable monitors are great for when you’re traveling or want some extra screen space when working from a cafe or even your hotel room. However, they also make for an inexpensive, second screen at home.  

Thanks to the 75 x 75 VESA holes on the back of the UPERFECT Delta, you can easily add it to your desk setup on a monitor stand or arm. Not every portable monitor comes with VESA mounting holes, so it’s nice to see that UPERFECT included them here. The hinge is strong enough too that you can have the upper display bent forward towards you like I did when trying out several stacked monitor setups.

UPERFECT Delta: The downs

The UPERFECT Delta is a big upgrade from using a single portable monitor with your laptop. However, there are some limitations and downsides you need to be aware of before deciding if this foldable, dual-screen portable monitor is for you.

Power limitations

The UPERFECT Delta is perfect for working on multiple screens from your laptop using a single cable if you have a powerful enough laptop. But even then, there are some limitations when it comes to using this dual-screen portable monitor. 

In my testing, I found that I wasn’t able to power both screens simultaneously when I had their brightness all the way turned up. This normally worked fine at 50% brightness but I had to drop the brightness down to 30% a couple of times.

The same goes for the UPERFECT Delta’s built-in speakers. You probably won’t be able to crank the volume all the way up, but for most people, this shouldn’t be a problem as the speakers on your laptop will provide better sound overall. The built-in speakers are good in a pinch though, especially when using the UPERFECT Delta with a game console.

You can always plug the device into the wall using the USB-C port on the bottom if you want to turn up the UPERFECT Delta’s brightness or volume. Fortunately, UPERFECT includes a 30W wall charger and all of the cables you need in the box. In fact, you get two USB-C to USB-C cables as well as two mini HDMI to HDMI cables.

Not your usual ports

Back when I bought my first portable monitor from UPERFECT for a Raspberry Pi project, it had a full-size HDMI port in addition to a USB-C one. However, as portable monitors have gotten a lot thinner, UPERFECT and other manufacturers have replaced HDMI ports with mini HDMI ports. 

This isn’t that big of a deal as you do get a pair of mini HDMI to HDMI cables in the box with the UPERFECT Delta. Plus, you can always pick up a pair of mini HDMI to HDMI adapters like these inexpensive ones ($9, Amazon) I got online, pictured above with another portable monitor I use at my main desk setup. That way, you can use a regular HDMI cable with the UPERFECT Delta instead.

When it comes to the UPERFECT Delta’s ports, I have one other gripe. If you want to have two people use one of its screens at the same time, you’re going to need to plug the device into the wall since there’s only one full-featured USB-C port. 

One person can connect their laptop using a USB-C cable but the other will have to use an HDMI to mini HDMI cable. This won’t be a problem at the office, but if you’re out at an event or working from a coffee shop, it might be hard to find a free power outlet.

UPERFECT Delta: Verdict

The UPERFECT Delta isn’t your typical portable monitor thanks to its foldable, dual screen design. As a result, it was quite expensive at launch with an initial price tag of $629. 

Thankfully, the price has come down significantly since then and it’s now much more affordable to build a portable dual monitor setup with it. You’re still paying a premium compared to buying two, 15.6-inch portable monitors but the convenience of a one cable solution is worth it in my opinion.

Most people will be fine using a single portable monitor with their laptop but if you have a multi-monitor setup at home, you’ll love being able to recreate this on the go. I do wish the UPERFECT Delta had two full-featured USB-C ports instead of just one but this won’t be an issue if you aren’t planning on sharing the device with someone else.

I’ve found that the UPERFECT Delta is perfect for traveling and I’ve brought it on trips for both work and for fun. I love how quickly you can set it up or break it down and the fact that it folds up like a laptop gives me peace of mind that its screens won’t get damaged in transit. If you’re a mobile power user, the UPERFECT Delta could be the perfect accessory for your laptop.
