hello, 

Please advise how to change a grey or discoloured white to be a clean white on a Acer Nitro RG270bmiix 27 Inch FHD Gaming Monitor, Black (IPS Panel, FreeSync, 1ms, ZeroFrame, HDMI, VGA)?

I have bought 3 new Acer Nitro RG270bmiix from different suppliers. The first one is great, and all the colouring looks good so I bought a second new same monitor. 
The second monitor has some kind of grey or murky discolouration. It's not terrible but it's not right. And since the monitors are next to each other you can see that the white's are different.
I've tried different cables, different slots on the monitor, different slots on the video card and it doesn't improve. I've also switched the cables between the two monitors and this doesn't change anything, my first monitor continues to look good, and second grey or murky.
I have a GeForce GTX 1060 6GB card. Latest Windows 10 PC. I have been through I believe every NVIDIA Control Panel setting AND every monitor manual button adjustment trying to adjust settings AND all Windows display settings but to no avail, I can't make the white as clean as the first screen. So I concluded the second monitor definitely has a fault. I purchased a third (same) monitor to replace the second, but I'm shocked to find it has exactly the same grey or murk discoloration as the second.

Please advise how I might fix these non clean white screens?

Thank you
