I’ve finally found a stackable monitor that I want to use

There aren’t many dual-stacked monitors on the market right now, which is why we were super keen to get our hands on the Mobile Pixels Geminos at the beginning of 2024. Unfortunately, the hefty weight and non-uniform shape left us rather underwhelmed and a little disinterested in the concept.

It was therefore with a lack of excitement that I unpacked Uperfect’s Delta Max Touch monitor. I expected it to be another bulky and gimmicky stacked monitor that lacked portability as well as quality. But I could not have been more wrong, as you’ll find out if you read on.

Stacked monitors are not for everyone, though, and you might prefer one of the best ultrawide monitors instead. If you’re just not sure, then our Ultrawide vs dual monitors – which setup is right for you? explainer is a great place to start. If you’re interested in what we’ve got to say about the Delta Max Touch, though, you’ll want to read on.

Uperfect Delta Max Touch: Key specifications

Design and build

• Dual 18.5-inch Full HDS IPS displays
• A well-built stacked monitor with sturdy hinges

Every time I handled the Mobile Pixels Geminos monitor, I was scared that I was going to break it or trap my fingers in the process. The construction and implementation didn't lend itself to any enjoyable interaction with it. My experience of the Delta Max Touch could not have been more different. Right from the beginning of unboxing the monitor, I was incredibly impressed by what Uperfect had achieved.

It all begins with the two 18.5-inch Full HD IPS touchscreen displays that are connected by a small yet more than capable hinge system. Unlike some connected monitors, this one stays in the exact position it is left in without succumbing to the alternative problem of being too stiff to operate. The hinge allows for a 360-degree folding rotation, so you can have any setup you desire, including folding it down into a more compact single-monitor setup.

The Delta Max Touch is VESA compatible, should you wish to mount it on an arm. I opted for the stand instead, which was more than capable of supporting the dual displays at any orientation I set them to. The inclusion of a set of rubber grips also helped to keep it from slipping or getting damaged. Additionally, I was amazed to find that it can be operated with only one hand without the stand losing. Well done, Uperfect.

The ports are located on the left-hand side of the bottom display with excellent coverage across USB-C and mini HDMI. I’ll cover more about connectivity in the performance section below, but suffice it to say that there is an abundance of flexibility when it comes to managing video, audio, and power. Uperfect also provides all the USB and HDMI cables you could need for any configuration. All I needed were some HDMI to USB-C adaptors so I could make it all work with my MacBook Pro.

Getting the monitor set up and connected couldn’t have been simpler. It’s even possible to manage video, audio, and power through a single USB-C cable to your laptop, but if you want to take advantage of more complex configurations, then you’ll need to use multiple cables.

Features

• Touchscreen displays with surround sound
• Ucare technology

The two 18.5-inch displays boast a 1920x1080 pixel resolution and a maximum of 120Hz refresh rate. It is possible to downsize the resolution and refresh rate, but I’m not sure why you’d want to, given that those specs are not particularly supercharged even at their top range. Both displays are touch sensitive, which is great to see compared to some stacked monitors that are designed with only a single touchscreen or none at all.

The monitors can be arranged to either clone, expand, or sequence, or if you’ve got two input devices, then you can make use of the StandAlong feature. I particularly liked the sequence option, which meant I could treat the two monitors as one large square monitor.

In terms of sound, Uperfect claims 3D surround sound courtesy of the built-in dual speakers. They call it ‘an immersive sound experience, as if you are in a theatre’, although I think that is pushing it. If sound is important to you, either on your creative projects or if you’re just listening to music for pleasure, then you’ll want some dedicated headphones or speakers.

Both monitors adopt Ucare low blue light technology, which reduces blue light by more than 80%. Over time, this should result in less eye strain and eyesight deterioration. This is ideal if you’re working for long hours or playing a lot of games.

Performance

• A lack of colour calibration
• Excellent clarity for IPS and good touchscreen performance

We’ve covered a fair amount of performance-related issues in the design and features sections, but there are a few more things to say.

Getting the monitor set up and connected was relatively straightforward, although I did have to play around for a little while with different cable combinations and display settings. I tested it using a MacBook Pro, and it seemed that there was a very specific order of doing things that let me separate the displays from one another.

Managing video, audio, and power is possible through a single USB-C cable to your laptop, but if you want to take advantage of more complex configurations, then you’ll need to use multiple cables. It’s also worth noting that you’ll need to use the dedicated charging cable and plug to get maximum brightness levels.

The IPS displays deliver a picture that most people would be happy with, but if you need absolute colour accuracy and depth, then the lack of a wide colour gamut and missing colour calibration could be a problem. It’s also inferior to what we would get with OLED panels, which provide perfect blacks and outstanding contrast.

As far as touchscreen accuracy and responsiveness go, I couldn't fault the Delta Max. It delivered a 100% successful response across the entire span of the displays, right to the edge. It also accurately tracked my finger, which meant I could trust it to do what I wanted.

Price

• Currently retailing at $799.99/£590.60

Uperfect’s Delta Max Touch monitor retails at $799.99/£590.60, although at the time of writing it was discounted down to $599.99/£442.95. The current awardee of the best portable monitor in our best monitors guide is the ASUS ZenScreen MQ16AH. Given that this costs £449 and is only a single monitor, the Delta Max Touch actually represents very good value.

Who's it for?

• Creatives who lack desk space but care about productivity

Dual-stacked monitors are not for everyone, but those who love them absolutely swear by them. This particular product is lightweight enough to genuinely be considered portable, with the hinge construction solid enough to cope with regular use. The Delta Max Pro is therefore perfect for creatives who are not limited to just one desk. The stackable setup also makes it ideal for video editors working on complex timelines.

Buy it if...

• You are short on desk space but still need a lot of display space
• You’re a video editor working on big and complex timelines
• You’re regularly multitasking with lots of open windows and long spreadsheets

Don't buy it if...

• You have room for two 24-inch monitors side by side
• You’re on a budget and can’t afford these more premium monitors
• You need 4k resolution either now or can envisage needing it in the near future
