A second monitor is one of the best productivity boosts you can get when using a MacBook Pro, but most monitors are not exactly portable. The Taihe Gemini is.
There are apps you can get to use an iPad as an external monitor, but a crowd-funded campaign has gone one better, offering a 15-inch portable monitor to match the size of the largest MacBook Pro screen. Unlike most existing portable monitors, it’s battery-powered, making for a truly mobile setup …
As we mentioned earlier this month, the Taihe Gemini is available in two versions:
- 15.6-inch 4K (3840×1920)
- 15.6-inch 1080p (1920×1080) touchscreen
The size and form-factor are the same, you just need to choose whether resolution or touchscreen capability is more important to you. Personally, while I can think of a few occasions on which a touchscreen Mac would be handy, the 4K resolution easily wins that battle, so it’s that version I tried.
I should say upfront that I’m using a prototype model. One of the purposes of a prototype is to provide an opportunity to iron-out any glitches in the design, and there did indeed turn out to be a couple in the model I got. The company has asked me not to go into details, but the wrong value was used for one of the circuit-board components, which means that it becomes unusable when the battery level gets low.
The rear casing was also loose on the prototype at the right rear corner when looking for the rear. Taihe says that it has already resolved both problems in early production units, and I’ll be able to confirm this once these are available.
Look & feel
The Gemini is a slab measuring 14 inches wide by 9 inches tall by half an inch thick. That’s near enough the same size as the 15-inch MacBook Pro. However, at two pounds, it weighs half as much.
The non-anodised aluminum casing is a rather industrial-looking mid-gray. The top and side bezels are thinner than a MacBook Pro, with a one-inch bezel at the bottom.
The rear has a logo, regulatory text and small icons for the ports and buttons, and a hinge for the built-in kickstand.
Connectivity and controls
The left side of the monitor has six ports:
- Power in
- Mini DisplayPort
- 2 x USB-A (2.0 in the prototype, 3.0 in the production model)
The right side has a headphone socket and five buttons, for power and cycling through the various settings.
The Gemini is plug-and-play with a MacBook. I tested it with my 2016 15-inch MacBook Pro with Touch Bar.
Flip out the rear kickstand to your desired angle, then hold in the power button to switch on the monitor. It displays the Taihe logo for a couple of seconds, then a No Input screen. You then connect to it using the supplied USB-C to USB-C cable. The monitor defaults to automatically detecting inputs (though you can opt to select manually), so with nothing else connected, it will recognise the Mac and spring to life. It takes 3-4 seconds to do so.
I found that it defaulted to mirrored output. I opened System Preferences > Displays to uncheck that box, and then arranged it as a second monitor to the left of the Mac.
