The signal from the CPU to the monitor is intermittent.

My monitor flickers off for several seconds. 

My monitor does not go off when it flickers off because the monitor blue light remains on all the time.

My system is Envy Desktop 795-00xxx.

• Video Cable: Ensure that the video cable (HDMI, DisplayPort, DVI, or VGA) is securely connected to both the monitor and the desktop.
• Power Cable: Verify that the power cable is secure and fully plugged in.
• Try Different Cables: If possible, try using a different video cable or connecting the monitor to another port on the desktop.

I moved the signal cable from the HDMI port on my desktop to the DisplayPort, and it solved the problem.

The cable had been in the HDMI port, untouched, for years. What could have caused the HMI port to display the error?

@xibmpopoo, I see you were interacting with @Kuroi_Kenshi however, he's away for now and I'd love to help you out!

Thanks for the update—and I’m really glad to hear switching to the DisplayPort fixed the issue! 🎉

As for the HDMI port acting up after years of faithful service—it’s actually more common than you'd think. Over time, heat, dust buildup, or tiny shifts in alignment from plugging/unplugging other cables nearby can affect the connection. Even if the cable hasn’t moved, slight oxidation on the port contacts can sometimes lead to an unstable signal.

If you ever need to use that HDMI port again, try giving it a gentle clean with a blast of compressed air or a soft brush. But for now, sounds like you’ve got a solid DisplayPort solution—rock on! 🎮🖥️

Wishing you smooth visuals and zero flickers ahead,

Hope this helps! 

Take care, and have an amazing day!
