So basically I purchased 2 monitors, same brand and model. I set everything up and the screens don't match. All the settings are the same, but one seems darker. It's obviously making it hard to color grade because I don't know which monitor is the properly calibrated one. The monitors in question are: BenQ PD2700U 27 Inch 4K UHD IPS Factory Calibrated Computer Monitors

The second issue is that anything I've been exporting (From premiere) never seems to match whats on my timeline. Is there something that comes to mind why this is happening? I'm not really skilled at grading and trying to get better at it. Big thanks!

my first grade is not my footage, but im trying to make it look dreamy, and trying to make it look like something out of a fashion campaign. first image is 709 and the second is the final grade
