4.2. USB Type-C Connectivity with Pass-Through Charging
If your device's Type-C port supports video output (DP Alt Mode), you can transmit video to the monitor using the included Type-C to Type-C cable. It also supports pass-through charging, providing up to 15W of power to connected devices. Connect to Nintendo Switch without a dock (Note: Switch 2 does not support video output via Type-C). For iPad Air/Pro, you can use mirror mode or extend your display like a PC using Stage Manager (check Apple's official website for compatible models). Please use the included Type-C cable for video transmission, as some Type-C cables only support power supply.

4.3. Versatile Adjustable Stand & Rear RGB Lighting
The HG-4K27C comes with a multi-functional stand that supports height adjustment, vertical/horizontal angle adjustment, and screen rotation (pivot). Adjust the screen to your preferred angle and height to reduce neck strain and ensure comfort. It is also VESA mount compatible, allowing for wall mounting or attachment to a monitor arm for flexible placement. The monitor's rear features RGB lighting, which reflects off the wall to create indirect illumination, enhancing the ambiance of your room and creating a stylish workspace for gaming, work, or movies.

4.4. Wide Viewing Angle & Accurate Color Reproduction with HDR
Equipped with a non-glare IPS panel offering a 178° wide viewing angle, images appear clear from any perspective. The non-glare surface minimizes reflections, providing a realistic and immersive visual experience. With 400nit high brightness, a 1200:1 contrast ratio, DCI-P3 95%/sRGB 120% wide color gamut, and HDR support for over 1.07 billion display colors (10-bit), this monitor ensures faithful color reproduction. Enjoy realistic images and immerse yourself in the visual world on screen. (Note: For Xbox, enable HDR10 by turning on HDR setting on the monitor and checking "Allow YCC 4:2:2" under General > Video Modes on Xbox.)

5. Setup
5.1. Stand Assembly
To assemble the stand, place the monitor face down on a soft cloth or the included foam packaging on a stable surface. Align the three tabs on the upper side of the stand pillar with the three holes on the monitor body. Push the lower part of the stand's circular plate into the monitor until you hear a click, indicating secure attachment. To remove the stand, pull the lever on the back to the right and lift the pillar from the bottom.

5.2. VESA Mount Installation
The monitor supports VESA mounting (75x75mm). The screw holes for the VESA mount are recessed by about 5mm. Therefore, you will need screws longer than 15mm or the included spacers. Using washers is also recommended. First, attach the long screws to the lower VESA screw holes on the monitor. Then, attach the short screws to the higher VESA screw holes. Finally, align the VESA arm with the screw holes, place it over the screws, and secure it with the black screws.

8. Troubleshooting
If you encounter any issues, please refer to the following common solutions:
- 4K Output Issues: If 4K output is not possible, try changing the refresh rate on your PC to 30Hz. This issue can sometimes be caused by conversion adapters or bandwidth limitations of the connected device. For example, if your PC's maximum output is 4K@30Hz but the setting defaults to 60Hz, 4K may not be selectable due to insufficient bandwidth.
- Unstable Type-C Connection: If the Type-C connection becomes unstable (e.g., "No Signal") due to static electricity during monitor use, we recommend connecting a grounding wire for stable operation.
- Initial Defects or Missing Accessories: All products are inspected before shipment. However, in the unlikely event of an initial defect or missing accessories, please contact our support team. We will respond responsibly.
