Introduction
This article aims to provide a solution to HDMIsplitter issues that occur when connecting a Dell laptop running Windows 11 to external displays using an HDMI cable and a HDMI splitter. This problem is not encountered when using the same setup on macOS.
Setup
The setup consists of a Dell laptop running Windows 11, an HDMI cable, and an HDMI splitter. One end of the HDMI cable is connected to the laptop, while the other end is connected to the HDMI splitter. The HDMI splitter then distributes the video signal to multiple displays, such as projectors.
Troubleshooting
Check HDMI Cable
Make sure the HDMI cable is not damaged. Try using a different HDMI cable to rule out any cable-related issues.
Update Graphics Drivers
Update the graphics drivers on your Dell laptop. Go to the Dell website, find the latest graphics driver for your laptop model, and install it.
Check Power Management Settings
Go to Control Panel > Power Options > Change plan settings > Change advanced power settings. Expand the "Display" section and make sure "Turn off display after" is set to "Never."
Disable HDMI Signal Format Conversion
Press the Windows key + X and select "Device Manager." Expand "Display adapters," right-click on your graphics card, and select "Properties." Go to the "Power Management" tab and uncheck "Allow the computer to turn off this device to save power."
Check HDMI Splitter
Try connecting the HDMI cable directly to one of the external displays without using the HDMI splitter. If the issue persists, the HDMI splitter might be faulty, and you may need to replace it.
When experiencing HDMIsplitter issues on a Dell laptop running Windows 11, follow these troubleshooting steps: check the HDMI cable, update the graphics drivers, check power management settings, disable HDMI signal format conversion, and test the HDMI splitter. If none of these steps resolve the issue, consider replacing the HDMI splitter.
