I have used
Acer V247Ybip for about a year and decided to buy
Acer V247bi to use for second monitor, which is basically the same monitor, but without the Display Port.
The problem is that basically I have 2 of the same monitors, but the colors differ quite a bit, the new one has more blackish blacks and the white is more red, compared to the older.
Both monitors are using the same settings for: Contrast, Brightness, Gamma, Profile Mode(which is named "cool"), but the colors differ.
The only different thing is that I use Display Port cable for the older one and HDMI 2.0 for the new one.
Here is reference to the models specifications: https://www.displayspecifications.com/en/comparison/2f87680d4
This problem is making me crazy and I think to buy monitor calibrator such as Spyder5 Pro, but I am not sure if it's worth the purchase. Can anybody tell me if at least this gadget lasts long time? If I can use it for at least 4-5 years, this will make this purchase more valuable.
And I want to ask one more thing, I think that one monitor is set with different color temps, than the other, like 50k and 65k. If some of you know a way to set this color temps manually and not just use the build in display modes, maybe I can fix the problem even without buying calibrator.
