Frequently Asked Questions :

1# Why does my Acer monitor keep going black?

Dealing with a monitor that frequently goes black can be frustrating, interrupting your work or entertainment experience. In this article, we will explore some common reasons why your Acer monitor may be experiencing this issue, along with possible solutions to help you resolve the problem.

  1. Power Saving Settings: One possible cause of your Acer monitor going black is power-saving settings. Check your computer’s power settings and ensure that the monitor’s sleep or power-saving mode is disabled or set to a longer duration. Adjusting these settings may prevent the monitor from going into standby mode too quickly.
  2. Loose or Faulty Cables: Loose or faulty cables can result in intermittent connections and cause the monitor to go black. Make sure all cables, including the power cable, VGA, DVI, HDMI, or DisplayPort cables, are securely plugged into both the monitor and the computer. Consider replacing any cables that show signs of damage.
  3. Faulty Graphics Card or Drivers: An issue with your computer’s graphics card or its drivers can also lead to a black screen on the monitor. Ensure that your graphics card is properly seated in the motherboard and that its drivers are up to date. Visit the manufacturer’s website or use automatic driver update software to install the latest drivers.
  4. Overheating: Excessive heat can cause monitors to shut off to prevent damage. Ensure that your monitor’s ventilation is unobstructed and free from dust. Additionally, check that the fans in your computer are working correctly and that the system is adequately cooled.
  5. Display Settings: Incorrect display settings can cause the monitor to go black or display no signal. Right-click on your desktop, select “Display settings,” and verify that the resolution and refresh rate are correctly set for your monitor’s capabilities. Adjusting these settings to match the recommended values can resolve display issues.
  6. Hardware Issues: In some cases, hardware problems with the monitor itself may be causing the black screen. If you have exhausted all other troubleshooting steps, consider contacting Acer customer support or a professional technician to diagnose and repair any potential hardware issues.

2# Why is my monitor black but still detected?

Encountering a situation where your monitor appears black but is still detected by your system can be perplexing. In this article, we will explore some possible reasons for this occurrence, shedding light on why your monitor may display a black screen while remaining recognized by your computer. Additionally, we will provide insights and potential solutions to help you address this issue.

  1. Incorrect Input Selection: One common reason for a black screen on a detected monitor is an incorrect input selection. Ensure that you have selected the correct input source on your monitor, matching the cable connection you are using (e.g., HDMI, DisplayPort, VGA). Use the monitor’s built-in buttons or on-screen display (OSD) menu to switch to the appropriate input source.
  2. Display Resolution and Refresh Rate Mismatch: A mismatch between the display resolution or refresh rate set on your computer and the supported capabilities of your monitor can result in a black screen. Access the display settings on your computer and confirm that the resolution and refresh rate are compatible with your monitor’s specifications. Adjust the settings accordingly to establish a proper connection.
  3. Faulty or Loose Cables: Faulty or loose cables can cause the monitor to appear black while still being detected by the system. Check all cables connecting the monitor to your computer, ensuring they are securely plugged in at both ends. If possible, try using different cables or swapping them out to determine if the issue lies with the cables themselves.
  4. Outdated Graphics Drivers: Outdated or incompatible graphics drivers may lead to a black screen on the monitor. Update your graphics drivers to the latest version provided by the manufacturer. Visit the manufacturer’s website or use driver update software to ensure you have the most up-to-date and compatible drivers installed.
  5. Hardware or Firmware Issues: In some cases, hardware or firmware problems within the monitor itself can cause a black screen while still being detected. Try performing a power cycle by disconnecting the monitor from the power source and leaving it unplugged for a few minutes. Then, reconnect the power and check if the issue persists. If the problem continues, consider contacting the manufacturer’s support or a professional technician for further assistance.


  1. Disabling Auto-Source Detection: Turning off auto-source detection might have contributed to the black screen issue, particularly if the HDMI cable wasn’t detected previously.
  2. Connectivity Problems: Faulty or loose cables, incorrect input selection, or incompatible cables can result in a black screen.
  3. Monitor Settings: In some cases, incorrect or misconfigured monitor settings can prevent the display from working properly.
  4. Hardware Failure: While less common, a hardware malfunction or defect within the monitor itself could be the cause of the black screen issue.


Before attempting any troubleshooting steps, it’s important to note the following:

  1. Check Warranty: If your Acer Predator XB273U is still under warranty, consider contacting Acer’s customer support or your place of purchase for assistance. Opening the monitor or attempting any repairs on your own may void the warranty.
  2. Be Gentle: When handling cables and making connections, be careful to avoid damaging the ports or cables.
  3. Electrical Safety: Ensure the monitor is disconnected from any power source before attempting any troubleshooting steps.


Troubleshooting Steps:

  1. Power Cycle the Monitor: Disconnect the power cable from the monitor, wait for a few minutes, then reconnect it. Power on the monitor and check if the black screen issue persists.
  2. Check Cable Connections: Ensure that the cables are securely connected to both the monitor and the respective devices (DP and HDMI). Consider trying different cables or swapping the connections to isolate potential cable-related issues.
  3. Reset Monitor Settings: If the OSD buttons seem to be functioning, you can attempt a factory reset. Press the appropriate OSD buttons to navigate to the menu option for resetting the monitor settings to their default values.
  4. Try a Different Power Outlet: Plug the monitor into a different power outlet or use a different power cable to rule out power-related issues.
  5. Test on Another Device: Connect the monitor to a different computer or laptop using both the DP and HDMI cables to determine if the issue lies with the monitor or the original devices.
  6. Update Firmware and Graphics Drivers: Visit Acer’s official support website and check for any available firmware updates for your monitor model. Additionally, ensure that your computer’s graphics drivers are up to date.
  7. Seek Professional Assistance: If the above steps fail to resolve the issue, it may be necessary to contact Acer’s customer support or a professional technician for further diagnosis and repair.

In conclusion
Encountering a black screen issue and the inability to access OSD options on the Acer Predator XB273U monitor can be frustrating, but there are several troubleshooting steps you can take to resolve the problem. Be cautious during the troubleshooting process and consider seeking professional assistance if needed. By following the steps outlined in this article, you increase the chances of getting your monitor back to full functionality.
