"Check Video Cable" and Occasional Screen Flickering Issues

[jdmathews17]

Hey everyone!

So, I have been having trouble with my HP Pavilion 23xw 23-inch IPS LED Backlit Monitor. My current setup is my Dell Inspiron 7547 laptop connected to the monitor via HDMI acting as the primary monitor. I also have a PlayStation 4 connected to the monitor's second HDMI port.

When my PlayStation 4 is running at the same time as my computer and I want to switch the input, I get the notification to "Check Video Cable". After this disappears, my computer runs just fine. This is purely irritating to me, but is there any way that I can stop this notification?

The primary issue that I have is occasional screen flickering on my monitor. When I am using my monitor, the screen occasionally goes black for about 5 seconds and comes back on. The length of time between flickers varies every time. I have tried updating my computer's graphic drivers, but it did not solve the problem. I have also tried replacing the HDMI cable, but it did not solve the problem. I have talked to many support agents, but they cannot solve my problem.

Does anyone have any ideas that I can try? I would love to be able to fix my issues!

Thanks again!

Welcome to HP Support Forums. 🙂 I came across your post and would like to help.

I understand that you have an HP Pavilion 23xw 23-inch IPS LED Backlit Monitor and the primary issue is that the screen flickers at times. The screen will go black for about 5 seconds. Secondly, when you try to switch the input when the Playstation and the computer are running at the same time, there a message to check the video cable. I appreciate the steps you have performed and have certainly done a good job.

I would like to know the following information to assist you better:

• Does the screen go black right from the time the monitor was purchased or it started recently?
• The monitor screen may lose signal while switching inputs but should be normal. But is the time taken to resume the signal too long?

Meanwhile, I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Power off the monitor.
• PLease disconnect the monitor from the computer and the display station. 
• Power on the monitor and it should say no input signal detected. This is known as monitor self-test.
• Observe the display in this mode and check if the screen goes black or if it flickers.

If the issue persists in a self-test then it is a monitor hardware failure and I suggest you to contact HP phone support to explore the hardware service options. If te monitor passes the self-test then you may continue with the below steps:

• Please download and install the monitor drivers for Win10 from this link. NOTE: Keep the monitor connected only to the computer while doing this update. 
• Also, try to connect the monitor to either the computer or the PlayStation and let me know if the display goes black or if it flickers.

Please feel free to let me know how it goes. Cheers. 🙂

Hi MKazi,

To answer both of your questions, the flickering has been happened since the monitor was purchased, which was September 19, 2016. The time for the signal to resume is about 10-15 seconds each time.

I will try out the steps that you have sent me to see if that solves my problem.

Thank you very much!

Hi MKazi,

I just tried the first set of steps and all that happened was the notifcation to "Check Video Cable". It never did anything else.

I will try out the driver update.

Thank again.
