U4025QW, MacBook Pro, color calibration issues

Question

I recently bought the Dell U4025QW. Upon connecting it to my MacBook Pro over Thunderbolt, I noticed a difference in the colors that I usually saw on the MacBook Pro screen and on my previous LG Ultrafine 5k. I set the display to the preset Display P3 color mode using the OSD and set the profile to "DELL U4025QW Color Profile, D6500, Display P3_V2" in macOS Display Settings but the colors are still off.

If you have figured out the right combination of settings to accurately match a MacBook Pro display, please help. Thanks a lot.

Then I was looking at the Factory Calibration Report included with the monitor. On the first page, it mentions that gamma for Display P3 was set to 2.6 (which is incorrect, it should be same as sRGB).

However, on the second page, if you notice the gamma curves on the right side, the curve for Display P3 (still mentions gamma 2.6) looks like the curve of sRGB and not like that of DCI-P3 (which also mentions gamma 2.6).

This makes me extremely confused about the state of factory calibration on this monitor.

I bought this monitor as a replacement for the LG Ultrafine 5k but so far, it has displayed colors incorrectly and provided contradictory calibration data. I am wondering if I made the wrong purchase?

Hey, It sounds silly, but the problem is the Thunderbolt cable. 😅 Try connecting with the high-speed HDMI cable that came with it, the colors should go back to normal. I was frustrated because my 27-inch 4K Dell looked better than this, even though this one cost 5–6 times more. Then I thought, “Maybe it’s the HDMI that makes all the difference,” and it turned out to be true. For the record I am using the latest macbook pro m4 pro.

@AidenSb​ Holy Moly thanks for that info, it is so much better with HDMI (Also on a M4 Pro btw).
