Windows 10: Cyan anomalies on monitor screen

In the last week I noticed a pronounced "cyan anomaly" when playing games (but also present on likes of MS Money). I attach a couple of screenshots by way of example.

Not sure what they are and why? Thought it was my graphics card so replaced that (upgraded to a rather tasty NVidea GTX 1660 Ti) but the same problem persists.

I have two monitors, the main one is a BenQ GL2780, the secondary a BenQ RL 2455. The cyan anomalies were always on the main monitor i.e. when I swapped the game over to secondary the anomaly disappeared.

That was until today when I find that the anomaly is now only on the secondary monitor (the RL 2455) but not present on the primary.

Aargh! Very confused .What is the problem? Can't be graphics card, can't see how it is monitors(?).

Have tried resetting monitors to factory, also swapped out all cables trying numerous combinations.

Any ideas? Any and all assistance gratefully received...

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Second monitor screen resolution problem

Hi,

For us to properly isolate the issue with your second monitor screen resolution, we would like to know the following:

• 
  Were there any changes made on your computer prior to the issue (e.g., updates, software installation)?
  
• 
  When did the issue first begin?
  
• 
  To make sure that we have not missed on anything, what troubleshooting steps have you done so far?
  

In the meantime, we suggest that you try resetting your monitor settings, and check if the issue still persists. You may refer to your monitor on how to reset it.

We look forward to your response.
