Taken on an iphone, I've of course exposed for the screens so the reddish/magenta color cast is pronounced. In reality, its a very slight hint of magenta but I want it to be as white and close to the 6500K light as possible. Macbook Air 13" screen for reference, and a 6500K light in my room for reference.

I have calibrated numerous times using an i1 Display and tried both softwares: BenQ's Palette Master Elements and i1Profiler, neither of which make the whites look truly white like the Macbook Air's screen does. The monitor temperature is set to 6500K, and I've of course selected D65 as my calibration temperature, along with standard 120cd/m3. What the hell is going on?

This is driving me mad, is my monitor defective? Please let me know ASAP so I can return before its too late. Thank you!

Is the Macbook's screen calibrated with your i1 as well?

Was your BenQ monitor reddish before you began calibration? Or did it seem more like the Macbook?

I tried before to use the same i1 to calibrate the Macbook, but I found that the profile it was making using the default settings was making the colors worse when changed from default (it was making the monitor give a warm picture and milky blacks) so I left it how it came from factory.

So it's odd but when I calibrated using BenQ's software, the color didnt actually change at all. I used the calibration validation tool and everything passed, it said it had some sort of delta < 0.35 or something. So I guess it came good to go from the factory. When using i1Profiler, it gets even more magenta! With nothing next to it, my eyes adjust I guess but it still "feels" magenta when I walk away and come back. Next to a Macbook screen or iPhone screen the difference is night and day. I really prefer the true neutral white look.

Any thoughts what I could be doing wrong?

Your monitor is a wide gamut monitor. Did you by chance set your monitor's profile to aRGB? If so, it is possible that your problem is not the profile of the monitor but is your browser not recognizing the color profile.

I don't know what browser you are using. I would assume Safari being you are using a Mac? I use Firefox and know it supports aRGB but you have to enable the profile for it to work correctly. Safari recognizes aRGB but it is possible that your version requires the correct settings to view wider profiles than the standard sRGB.

A simple thing to try would be to look at true white sRGB images on the browser. See if they are actually white. Then see what happens when you look at a true white with a aRGB profile. May not be your problem, just giving you one more thing to eliminate.

White with a sRGB profile.

Edit: I tried to create an aRGB image. My attempt to set the profile may not have worked. I tried to test the images and I can not verify that the bottom image is aRGB. I left it just in case it is.
My old EXIF viewer would have verified the profile, but the new one does not. The old version is not compatible with the newest Firefox. :-(

White with a aRGB profile. These should look exactly the same (except for the forum added frame.) If they don't, your problem is probably your browser settings, not your monitor profile.

Does the TF actually know about the soda cans and PVC pipe from 30 years ago?

Two things to consider for each display - the white point and the luminance. You are using the MacBook as a reference, perhaps it sounds like it is not a reference that is calibrated to D65 and the luminance level is not known. The MacBook display may be set to its native white point, which is probably higher than D65, although I am guessing.

You can try to measure the output of the MacBook with the i1 device (WP and luminance) and use the values that result as the target for your BenQ. You may have better luck this way if you really want to match the laptop display.

Nogo, appreciate the response but I know this is not a browser issue because I am speaking of the monitor's overall color in any application, even just Windows file explorer.
