I have 2 BenQ SW2700's and it was a pain in the ass to get them to match when I did the first calibration. I have a Datacolor Spyder5 I used with Benq's software. I had to redo it multiple times and some of them were way off. I am not a 100% it's still correct my prints are close but we but I have not really printed much since I got the monitors. Anyway, my issue started when we were looking at colors to paint our house. We looked at a few online then went and got color swatches. When I compare these to what I see on the monitor there are not even close. I am tempted to buy an x rite i1 but don't want to spend 250 if there is something else I am missing. Thanks for the help.
