Your acer monitor keeps turning off and on? Don’t worry. To fix the problem, you can try these methods:
Method 1: Check your video cable
When you see your acer monitor keep turning off, the most possible cause is a loose or damaged video cable, the cable connecting the monitor and the video card, for example, an HDMI cable.
Firstly, unplug the video cable from both the PC end and the monitor end, and then replug the cable. Ensure the cable is inserted tightly at both ends.
If the problem persists, replace the video cable with a new one. Before buying a new cable, you may want to test the video cable on another system. If the cable also doesn’t work on another system, there’s a big chance that the cable is damaged.
Method 2: Reinstall the graphics card driver
If you see the problem occur after an update, it’s possible the graphics card driver is causing the monitor turning off issue. To fix the problem, you can try to reinstall the graphics card driver. Here’s how:
1) Press Win+R keys to open the Run box.
2) Type “devmgmt.msc” into the Run box and click the OK button. Then the Device Manager window will open.
3) At Device Manager, expand the category “Display adapters”, right-click on the graphics card driver and select Uninstall.
4) Restart the computer to allow Windows to reinstall the graphics card driver.
If the problem still persists, you can navigate to the graphics card manufacturer’s website to download the latest version of the graphics card driver and then install it to see if it helps fix the problem.
Method 3: Reconnect the video card
If your video card isn’t getting enough power, the monitor can keep turning off. Open your computer case, disconnect the video card from the power supply at both ends and then reconnect it. Ensure the connectors are in all the way.
After that, check to see if your monitor still keeps turning off. If the problem still persists, you may want to contact a tech person for a further check, as the video card might be faulty.
Method 4: Check your monitor
The problem can be caused by a faulty monitor. To troubleshoot, you can connect your monitor to another computer. If the monitor also doesn’t work by connecting to another computer, the monitor is probably faulty.
Alternatively, you can test with a different monitor. If another monitor works without the problem, your acer monitor could be faulty.
If you verify the monitor is faulty, you can replace the monitor with a new one, or contact a tech person to have a further check.
