Overview
The ZX173BQ (formerly sold as the K7) offers a 17.3-inch 1440p IPS panel at 144Hz with HDR. The larger size and QHD resolution make it a strong portable option for laptop and console gaming.
Who it is for
Gamers who want a big, sharp and fast portable monitor. It is sold by the official UPERFECT store (uperfect.com) in US dollars, and this page links to that store.
What to check before buying
Check that your laptop or phone supports video over USB-C (DisplayPort Alt Mode or Thunderbolt); if not, you will need HDMI and separate power. Match the refresh rate to your use: 60Hz is fine for office work, 120–240Hz helps gaming. For consoles, the console itself may limit resolution and refresh rate. Touch screens usually need a USB data connection to work.
Setup tips
Use the cable that came in the box first; many issues come from USB-C cables that only carry charging. Set scaling in your operating system for high-resolution screens, and lower brightness on battery to extend runtime.
