The Cable Matters 18Gbps HDMI to DisplayPort adapter supports the 4K @60Hz resolution. Turn a device's HDMI port into a DisplayPort port for connecting to DisplayPort monitors up to a resolution of 4K@60Hz.
General Troubleshooting Steps
Try lowering the resolution and refresh rate settings.
Test cables with another device.
Unplug the adapter and cable, reboot or restart all devices, and reconnect the cable and adapter.
Test the adapter with another device.
Connect the USB cable to a USB wall charger.
Make sure you are connecting the adapter to an HDMI 2.0 port for maximum resolution support. Check your device manufacturer’s instructions for details on locating an HDMI 2.0 port.
If an Xbox Series X or a PlayStation 5 is connected to a 4K monitor, the adapter does not work. The monitor does not function at all, or displays a resolution error or timing error.
On certain 4K DisplayPort monitors, the PlayStation 5 and Xbox Series X may be unable to achieve the highest resolution and refresh rate supported by the monitor. If this occurs, the monitor may not function at all, or the monitor may display an error. The monitor may display a lower resolution by default. This is due to a compatibility issue with certain monitors. Certain monitors cannot accept the pixel clock rate the PlayStation 5 and Xbox Series X sends at specific resolutions and refresh rates.
To resolve this issue, lower the resolution and refresh rate of the Xbox Series X or PlayStation 5. On 4K monitors affected by this issue, Cable Matters recommends a 1440p resolution for the Xbox Series X and a 1080p resolution for the PlayStation 5.
1) Power off the PlayStation 5 by pressing and holding the power button on the console for 3 seconds.
2) When the system powers down, hold down the power button again. Wait for the console to beep twice. The console will turn on and a Safe Mode menu will appear.
3) Connect the controller to the console’s USB port, and press the controller’s PS button.
4) From the Safe Mode menu, select “Change Video Output,” then select “Change Resolution.” A message will appear to restart the PlayStation 5. Press OK.
5) When the PlayStation 5 restarts, select the “1080p” resolution from the list of choices. The console should now function in the 1080p resolution.
Xbox Series X
The Xbox Series X console should automatically lower the resolution and refresh rate to one that works with the monitor. The recommended resolution is 1440p. If it does not, follow these instructions to adjust the resolution and refresh rate. NOTE: If the adapter does not work, you may need to complete these steps by connecting the Xbox Series X directly to a display.
1) From the Xbox Series X main menu, open the Home menu and select “Settings.” Then navigate to “General” > “TV & Display Options.”
2) From the Display Resolution drop-down box, select 1440p. If your monitor supports high refresh rates, select the optimal refresh rate from the Display Refresh Rate drop-down box.
3) Close the menu.
