Faulty cable or faulty monitor?

[treeroy]

My second monitor is very glitchy. It cuts off and on very frequently. As if it has a loose connection.

 

I am unsure if this is being caused by the cable or the monitor. It's a HDMI-to-VGA cable. The VGA is the only port on the monitor, and I have no other VGA devices to test the cable on. The cable is fairly new, maybe 1 year old, and the monitor is 10 years old. I have inspected the cable and I dont see anything loose or damaged.

 

Any advice welcome as to how to fix this. Thank you.

 

Video is of the cutting in and out. The photo is from a few days ago when the monitor just turned to static and would not work when I pulled the cable out and back in. I restarted the PC and it was working again.

Usually is the cable. Snowy picture would be a handshake failure with HDCP (which VGA does not support anyways). Drop-outs and loss of sync can cause snowy picture as well. They all tie back to a bad connection or cable usually.

I think it could be either or. Or even bad port on the GPU. I would try another cable first tho. And plugging it in to another port on the GPU if you have other ones.
