U2515H, two, not the same color
I have a U2515Hc since quite some time and have just bought a second U2515H (without c, as I saw when unpacking). But the difference in color is quite huge (see photo). I tried different screen settings, but it hasn't changed at all. I saw a similar conversation here, where it seems the solution was to send back the screen. Which would be annoying, and would pose the question how to choose then a second screen anyway if the differences are so big.
Can someone give me a hint what to do? Thanks for any advice.

Click my name and private message me both of the U2515H service tag numbers, U2515H 20 digit serial numbers. Using that data, I can tell when they were built and sold.
They are both the same monitor model, U2515H.
c= regulatory notation
X = HDMI cable instead of DP to mDP cable
Both of them should be reset to Factory using the Menu OSD -Others -Factory Reset. But even then, the colors may not match and still be within manufacturer specifications. All Dell monitor panels are uniquely calibrated at the factory to their own unique panel. No two panels are identical, even of the same model. If you want a closer match, you will need to purchase calibration hardware (colorimeter) and software. Then calibrate both monitors.
