Product Note
The XG129C is a compact secondary touchscreen monitor, not a conventional full-size desktop display. Its 1920 × 720 resolution and 24:9 aspect ratio are optimized for narrow, ultrawide content rather than standard 16:9 viewing. Touch input and video transmission require compatible host-device connectivity and software. Confirm the regional port configuration, power adapter, included cables, and mounting accessories before ordering.
