Display blanks or statics periodically?

[Andyy58]

So I recently purchased the Viotek curved 144hz 1080p monitor from Amazon, and in my first days of using it, everything was fine, the colours were great, and there were no problems. But starting around 3 days after I started using it, the monitor would start to lose connection for 1 - 2 seconds sometimes over a period of time, where the panel would completely turn off, or sometimes it would flash to static for a split second and then be working just fine again.

 

I have it connected via HDMI to my late 2013 MacBook Pro Retina and displaying 120hz. I have a suspicion that this could be caused by the HDMI cable, as it was not included with the monitor, so I just grabbed one from my basement, and I didn't have this problem with the AOC 144hz 1080p Freesync Gaming Monitor I used earlier, that had an included HDMI cable.

 

Can anyone confirm my suspicions? Because I don't want to buy an HDMI cable only to find out that wasn't what the problem was.

 

Here are the monitors I mentioned:
