HPE EliteBook 840 G4 Not Providing 1080p Resolution Output on Second Monitor
The HPE EliteBook 840 G4 is a powerful and versatile laptop, designed for professionals who require high performance and reliable hardware. However, some users have reported an issue with the laptop's display output when connecting to a second monitor via DisplayPort or HDMI cable. Specifically, the second monitor is not providing a 1080p resolution output.
Understanding Display Resolution
Display resolution refers to the number of pixels that make up the display on a screen. A higher resolution means more pixels, which can result in sharper and clearer images. 1080p, also known as Full HD, is a popular resolution for monitors and televisions, with a resolution of 1920 x 1080 pixels.
Checking Display Settings
When experiencing issues with display output, the first step is to check the display settings on the laptop. To do this, follow these steps:
- Right-click on the desktop and select "Display settings".
- Under "Select and rearrange displays", make sure the correct monitor is selected as "1" and the second monitor is selected as "2".
- Under "Resolution", select "1920 x 1080" for both monitors.
Updating Display Drivers
If the issue persists, it may be due to outdated display drivers. To update the display drivers, follow these steps:
- Right-click on the Start button and select "Device Manager".
- Expand the "Display adapters" section.
- Right-click on the display adapter and select "Update driver".
- Select "Search automatically for updated driver software" and follow the prompts to install any available updates.
Checking Cable Connection
If the issue still cannot be resolved, it may be due to a faulty cable. Make sure the DisplayPort or HDMI cable is securely connected to both the laptop and the second monitor.
Contacting HPE Support
If none of the above solutions work, it may be necessary to contact HPE support for further assistance. They may be able to provide additional troubleshooting steps or arrange for a repair or replacement if the issue is due to a hardware fault.
