Q: Is there a site or program where I can compare visually an image between two iMacs for comparing resolution quality?

Is there a site or program where I can compare visually an image between two iMacs for comparing resolution quality?

 

I have two iMacs next to each other and need to compare the monitor quality and need something visually that can determine the difference pixel by pixel, rather than just throwing on the same photo on both screens in fullscreen view mode as that sometimes can't do the job with the naked eye.

MacBook Air, OS X El Capitan (10.11.6)

    Do a Google, Bing & DuckDuckGo search for such a site or program.

    With an external calibration product to assure the screens are of the same appearance

    then other aspects of the image appearance may be better understood. Before trying to

    find or buy a third-party calibration, see what the built-in macOS display options do first.

     

    There is a hidden (opt/click) key to exhibit more options (depends in version OS X) in the

    Display control preferences (that I haven't used.)

     

    Just saying, that if their respective settings are not comparable, then visual is not likely.

    Each machine can be a little bit different. As BabyBoomer suggests, an online search

    may (or may not) be a method of locating software or hardware solutions in this regard.

     

    Good luck & happy trails!

    Are the iMacs identical (same model number)?

    Do they have the same graphics processor (GPU)?

    If they are identical, do the have roughly the same number of hours

    of usage?

     

    If the above are true, you could use the visual calibrator available

    in Display Preferences on one of them.  You could then use the icc

    profile from it on the other iMac.  It should be pretty close if the

    above are all true.

     

    If they are totally different models and years, then you may need

    to resort to a calibration device depending on how close they need to

    match.  If "close enough" is sufficient, just use the built in visual calibrator

    on both.  You need to make very sure that the calibration is done under

    exactly the same conditions, i.e. find a spot you can put them and also

    be sitting at exactly the same distance from them.
