New battery-powered portable monitor not terrible

The Taihe Gemini is a slim, battery-powered 15.6' touchscreen display that's raised more than $1m at Kickstarter. The Verge's Sam Byford took it for a spin.
The pre-production version I tested has a matte 1080p touchscreen. It’s not the most beautiful display in the world, with pedestrian color reproduction at 72 percent of the NTSC gamut, but it is at least an IPS panel with solid viewing angles. There’s also a 2mm-thicker 4K model that omits touch functionality but achieves a claimed 100 percent of Adobe RGB coverage. I wasn’t able to test that version, so I can’t speak to its supposedly better color performance.
The touch functionality on the 1080p model sadly doesn’t extend to its janky button-operated settings menu, but it’s actually pretty cool if you have a compatible phone with a desktop mode, like a Samsung Galaxy Note with Dex or a Huawei device that supports Easy Projection.
I'm quite eager to see this myself: sounds perfect for using in portable MAME cabinets, retrofitting into dead terminal monitor cases, and other assorted witchcraft.
