What is the native Android resolution on my CommBox screen?

Most CommBox screens run Android in native 4K resolution—giving you crisp visuals and smooth performance straight out of the box.

Applies To

  • Classic S4, S5
  • Atom
  • Pulse
  • Horizon
  • Classic V3, V3X and Commercial Display V4 (see note below)

Understand Android resolution on your screen

  • All CommBox screens with Android run native 4K resolution (3840 × 2160) on the Android system.

  • This ensures everything from apps to menus looks sharp and detailed.

Know the exception

  • The Classic V3, V3X and Commercial Display V4 model runs Android at Full HD (1920 × 1080).

  • However, you can still enjoy full 4K resolution by connecting a 4K external device.

How to make the most of your 4K screen

  • Connect a PC, Mac or laptop that supports 4K output using HDMI for video and USB Touch for interactive control.

  • The CommBox OPS (Open Pluggable Specification) PC also supports native 4K output, giving you a seamless high-resolution experience.

💡 Tip: Always check your connected device's display settings to ensure it’s outputting at 4K for the best performance.

Troubleshooting / What to Do If It Doesn’t Work

  • If the display looks blurry or not as sharp, check your input resolution settings.

  • Ensure HDMI and USB touch cables are securely connected.
