The UPerfect Delta Max touchscreen monitor offers so much potential, but I found it wasn’t quite as straightforward as it should have been in my tests

TechRadar Verdict

The concept for this stacked 18.5-inch dual monitor touchscreen that offers a 100Hz refresh rate is interesting, with its simple plug-and-play connectivity. This enables you to quickly expand your workspace whilst minimising the additional monitor's footprint. It also adds touchscreen support to compatible machines. There's no doubt that the design is incredibly clever. One USB cable can connect to the dual stacked monitor, providing much-needed additional real estate for laptops as well as mini PCs. Unfortunately, connection and configuration aren’t straightforward, and whilst the concept is good, the execution of some of the hardware is just too hard to fathom.

Pros

• +Small footprint
• +AOU Monitor Support
• +HDMI and USB connectivity

Cons

UPerfect Delta Max: 30-second review

The UPerfect Delta Max stacked monitor is a great idea, essentially two monitors, one on top of the other, in a clamshell design with a full metal build that makes it easy to transport and connect. However, from the outset, it's not quite as easy as it seems, and the single USB connection only gives you limited options over how the display works. Sure enough, it is able to mirror or extend the display from your laptop, be that Mac or PC, but the additional options just aren’t as well integrated as you feel they should be, and it takes quite a bit of messing around with the options and settings both on the machine and on the monitor to get it configured exactly as you want.

This use doesn’t initially give you the option to use it as a triple monitor system, so, for example, your laptop monitor and then two additional displays, one stacked over the other. Instead, what it gives you is either a mirror of your laptop display on those two monitors or a display extension, but with the same extension being shown on both and not two different screens, as you’d normally expect with a triple monitor setup. It’s a little bit confusing, and if you want to use this with anything other than a relatively high-powered MacBook Pro or higher-end PC, then you’ll also find that you’ll need to plug in external power.

To get the actual configuration that I was expecting in this test, I ended up having to plug in external power to the USB-C port at the base of the monitor than another USB-C into the USB port, and a second HDMI cable into one of the upper clusters of ports and then into the MacBook Pro in order to get that triple-screen array that I wanted.

Then I could either configure the way the monitor displayed the content through my computer's display options, or there were a few additional configuration possibilities through the monitor’s on-screen display, although these didn’t always seem to work.

Essentially, it all works, but it does take quite a bit of figuring out. Thankfully, UPerfect has included a decent amount of cables in the box, so you're not having to search around for extras or purchase anything in addition.

In use, the monitor actually works surprisingly well, and I really do like that small footprint. However, when running several tests, I came across a number of small glitches, such as the monitor would flicker on and off, or one would suddenly go blank when loading up another bit of software. Also, if my laptop went to sleep and then reawakened, which is common, especially when I disappear for lunch, then I'd have to reset the monitor, as it seems to lose its settings.

When I ran through the usual SpyderX benchmarking test to check out the quality of the screen, it also came out pretty well. It highlighted that the screens are perfectly suited for office work; however, this won't be the best portable monitor for creative use, as the AdobeRGB percentage for the gamut was in the high 60s. Really, if you want to do anything creative, you need a monitor that at least comes in around 80% plus. However, for office work, it is a good solution once you figure it out.
