As spotted by Gizmodo, the screen comes from Elsonic, a sub-brand of Japanese company Nojima, which started off with LED bulbs but now makes TVs and other tech products. The product page for the tall monitor specifically highlights web browsing, Twitter, and browser games as use cases.
The display is only 8.8 inches, so it would best serve as a portable, secondary or tertiary monitor. It charges via USB-C but can't output video through the port. The monitor relies on mini HDMI for its video signal. That gives it a little versatility in the sense that it can connect to things lacking USB-C. But with more PCs ditching HDMI, and the monitor already having a USB-C port right there, it feels like a missed opportunity.
Built like a New York City skyscraper, the EK-MD088 takes up minimal surface space. Its base is approximately 3.07×0.83 inches (78×21 mm), and it towers 9.76 inches (248 mm) into the sky. The display should make an easy portable monitor (assuming you can find a case to accommodate its dimensions), as it only weighs about 0.43 pounds (198 g).
A 420×1920 resolution gives the TFT panel an aspect ratio of 7:32. A picture wasn't provided, but the stand is supposed to allow for landscape mode, too.
Elsonic's listing doesn't get into color capabilities but says the screen has a standard refresh rate of 60 Hz and a typical brightness of 300 nits. The screen has two buttons on the side that let you pick between six brightness settings.
Currently, the monitor is only available in Japan. So if you’re really craving this type of unit, you may have to act as an importer to get it. It's expected to release in "early February," the product page says, for 14,800 yen, which is about $128.21.
