What Comes in the H32U6 Box?
The box includes the monitor, base, power adapter, HDMI signal cable, and user guide with warranty card. Check the contents and the adapter label before setup. If anything is missing, contact our support team with the model number, order details, and a photo of the package contents.
How Do I Attach the Base?
- Turn off the monitor and disconnect all cables.
- Put it face down on a clean, soft, flat surface; do not press on the screen.
- Align the base and stand parts so they fit together without force.
- Secure the parts and check the lock before lifting the monitor.
- Lift by the body and stand and place it on a stable desk.
To remove the stand, release its lock before separating the parts. Do not pull on the panel.
Where Should I Place the Monitor?
Leave about 10 cm of clearance around the sides and back and about 30 cm above the monitor. Keep vents uncovered and avoid an enclosed shelf without airflow. Put the display near an accessible outlet and away from heat, moisture, and strong vibration.
How Do I Connect a Desktop or Laptop?
- Connect the supplied adapter to the monitor and an accessible outlet.
- Use one direct HDMI or DisplayPort cable from the computer to the matching monitor input.
- Turn on the computer and monitor.
- Use the joystick's up shortcut to choose the connected input.
- In the computer's display settings, select
3840 x 2160and60Hz.
If your laptop uses only USB-C, its adapter or dock must support video output and the desired 4K mode. Test a direct HDMI or DP connection when available before troubleshooting a dock.
How Do I Set 4K at 60Hz?
Both HDMI 2.0 and DP 1.4 support 3840 x 2160 @ 60Hz. Select the H32U6 in the operating system's display settings, then choose that resolution and refresh rate. If the picture disappears, try 1920 x 1080 @ 60Hz, reconnect the cable, and test the 4K setting again with a compatible cable and source output. At 4K, adjust operating-system scaling for comfortable text size rather than lowering the native resolution solely to enlarge text.
How Do I Use the Joystick Menu?
| Joystick action | Shortcut before the menu opens |
|---|---|
| Up | Input/source selection |
| Down | Brightness |
| Left | Gaming assistance or return, depending on menu state |
| Right | Preset mode or selection |
| Short press | Power on or open the main menu |
| Press and hold about 3 seconds | Power off |
Inside the menu, use up and down to move, right to enter or confirm, and left to return. For a dark or uncomfortable image, adjust brightness first, then contrast or picture preset.
Can I Mount the H32U6 on a Monitor Arm?
The H32U6 supports a 100 x 100 mm VESA mount (M4*10). Power off, unplug every cable, place the display face down on a soft surface, and release the stand. Use a compatible bracket that supports the monitor's weight. Confirm the screw length against the monitor and bracket before tightening.
How Do I Clean and Store the Monitor?
Unplug the display before cleaning it. Use a soft, slightly damp cloth and avoid spraying liquid directly onto the panel. Do not press the screen with hard objects. Store the monitor in a dry, ventilated place and keep the panel protected during transport.
Troubleshooting H32U6 Problems
The monitor will not turn on
Check the outlet and power connections, then short-press the joystick. Check the adapter and monitor labels if you are unsure about the power supply. If the power indicator remains off, contact our support team with a photo of the adapter label.
The power indicator is on, but the screen is black
Press the joystick to see whether the on-screen menu appears. Choose the input matching your cable, reconnect both ends, and test one direct cable at 1920 x 1080 @ 60Hz. Try another input or source device if available.
4K at 60Hz does not appear
Verify that the source output, cable, adapter or dock, and selected port all support 3840 x 2160 @ 60Hz. Test a direct HDMI 2.0 or DP 1.4 connection where possible, then select the resolution again in the operating system.
Text looks small, blurry, or stretched
Set the source to the native 3840 x 2160 resolution. Increase operating-system display scaling for larger text. If the image remains blurry, reconnect the cable and compare another input or computer.
The image flickers or looks distorted
Return to 60Hz, check that the cable is fully seated, and remove any splitter or adapter for the test. If needed, compare another cable or source device.
Frequently Asked Questions
Can either HDMI or DP display 4K at 60Hz?
Yes. Both HDMI 2.0 and DP 1.4 support 3840 x 2160 @ 60Hz, provided the source output and cable support that setting.
Does the monitor have a USB-C input?
No. The H32U6 has HDMI and DisplayPort video inputs. A laptop with USB-C video output needs a compatible USB-C-to-HDMI or USB-C-to-DP cable or adapter.
How can I make text larger without losing 4K sharpness?
Keep 3840 x 2160 selected, then raise operating-system display scaling. This enlarges interface text while preserving the monitor's native pixel resolution.
