Linux users hunting for a high-resolution, color-accurate monitor with proper DDC/CI support now have another option worth considering. The Kuycon P20 is a 71.6 cm (28.2-inch) IPS panel running at 4.5K resolution in a 3:2 aspect ratio, packing 192 PPI and 10-bit color depth with 99% DCI-P3 and 99% sRGB coverage. It delivers 500 nits of sustained brightness, a 1500:1 contrast ratio, and HDR600 certification.

The 3:2 aspect ratio is the standout feature here. That extra vertical space compared to a standard 16:9 panel makes a real difference for coding, document editing, and web development, where you spend most of your time scrolling. At 192 PPI, the pixel density is optimized for HiDPI scaling, which works well across macOS, Windows, and modern Linux desktop environments running Wayland or X11 with fractional scaling.

Connectivity covers USB-C, HDMI, and DisplayPort, and the monitor supports the DDC/CI protocol for software-based brightness control. On Linux, tools like ddcutil can talk to the display directly, while macOS users can use MonitorControl and Windows users can reach for Twinkle Tray or Monitorian. The monitor ships with a VESA adapter for arm or wall mounting, with an adjustable stand available as a separate purchase.

The Kuycon P20 starts at $799 (€735) and ships worldwide through the company's US dealer.
