Unlike traditional side-by-side monitors, this vertical design fits neatly into tight workspaces, making it ideal for users who need more screen real estate but lack horizontal room. When folded, the unit measures just 355×23×215mm and weighs about 1.6kg — roughly the size of a 15.6-inch laptop. It connects to a PC via a single USB Type-C cable (with the included AC adapter for power) and is ready to use immediately. ## Connectivity & Compatibility The PUHD26HBK offers three video input options: HDMI, DisplayPort, and two USB Type-C ports. The included USB-C to C cable handles both video and power delivery simultaneously, but an AC adapter (DC20V 2.25A) must be plugged into a wall outlet — USB bus power alone is insufficient. Compatibility spans Windows PCs, Macs, and select Android devices. For Mac users, Multi Display Mode (two independent screens) is only supported on M1 Pro/Max, M2 Pro/Max, and M3 Pro Max chips. Other Macs are limited to Full Screen Mode (one large canvas) or Mirror Mode. Windows users should ensure their GPU and USB-C port support DisplayPort Alt Mode for 4K output. A 3.5mm headphone jack and built-in stereo speakers (4Ω 2W×2) are included, so external audio gear isn't strictly necessary. ## Product Info The warranty period is 12 months from purchase. In the box you get the monitor unit, a quick-start guide, USB Type-C to C cable, AC adapter with attached Type-C cable, HDMI cable, and DisplayPort cable — everything needed for immediate setup. Market positioning: this is a niche product that creates its own category — a vertical dual-monitor portable display. It's more expensive than buying two basic monitors, but the space-saving design, unified build, and included cables justify the premium for the right user. ## Best Use Cases Remote workers with cramped desks If your desk can't fit two monitors side by side, stacking them vertically is a smart workaround. The PUHD26HBK sits neatly next to a laptop without requiring extra width. Just be aware that the vertical height may require adjusting your chair or monitor stand to maintain a comfortable viewing angle. Programmers and engineers Place your code editor on the top screen and a browser or terminal on the bottom. The 4K resolution keeps small fonts crisp, and the anti-glare coating reduces eye strain during long sessions. However, some IDEs with toolbars at the top and bottom may have content hidden behind the bezel gap, so you'll need to tweak your layout. Assign your timeline to the bottom screen and preview to the top for a more efficient workflow. Professional colorists should note that DCI-P3 and Adobe RGB coverage aren't specified, so calibration may be necessary. ## Alternatives If you only need one extra screen, those are more cost-effective. The real alternative is buying two separate 15.6-inch monitors and mounting them vertically with a VESA arm. That route can cost as much or more than the PUHD26HBK, plus you'll deal with messy cables and a more complex setup. The THANKO's all-in-one design wins on simplicity and tidiness. ## Things to Consider First, the PUHD26HBK absolutely requires the included AC adapter — it cannot run on USB bus power or a power bank. This limits its portability to locations with wall outlets. Second, Mac compatibility is restricted: only M1 Pro/Max, M2 Pro/Max, and M3 Pro Max chips support true dual-screen mode. Other Macs are stuck with mirror or full-screen modes. Windows users should verify their GPU and USB-C port support dual 4K output. Third, the 25ms response time and 60Hz refresh rate make this monitor unsuitable for fast-paced gaming. Competitive FPS or racing game players will notice motion blur. Finally, while the monitor has a 75×75mm VESA mount, THANKO does not officially support arm installation — you'll be on your own if you choose to mount it. ### Product Disclosure (Amazon) - Manufacturer: リアンリー(Li LIAN LI) - Seller: Amazon.co.jp - Fulfilled by: Amazon.co.jp - ASIN: B0B469JRGC - Note: This article covers a manufacturer-made product based on Amazon listing details.
