color mismatch on same monitor models

grifter56

i bought an Acer GN246HL on black friday then last week i decided to take the plunge and get another so my dual monitos match.  I bought the exact same model as before but now there is a slight color difference in between them.  The original monitor has a cooler color temperature.  I went throught the on screen menus and made sure the settings were the same.  Both are connected with via DVI to the same video card.  I am running windows 10 i did not see any drives for 10 but i saw 8.1 drivers i installed those and it added the color profile to the color management but the colors are still a little off.  Also, tried swapping the cables with same results.  this is a little annoying becuase one mof the reasons i got the second monitor was the samsung it replaced had a slights off color as well.  do i have to return this monitor or is there a way to resolve this.
