dennersten Posted July 17, 2016 Share #1 Posted July 17, 2016 Advertisement (gone after registration) My wife who is a graphical designer needed to swap computer to a new Macbook Pro recently. Please have a look at the attached picture. The grey ”smudges” in the white area can’t be seen in my wifes computer. Seems like a lot of midtones are lost globally in all programs. Same weird behavior i Safari, Photoshop, Indesign, Finder etc. After 2 hours fiddling around with screen profiles and a lot of googling i am giving up. Are there anybody here who please can help??

Exodies Posted July 17, 2016 Share #2 Posted July 17, 2016 Could you display a grey scale on her computer and photograph it; post the result here Quote Link to post Share on other sites More sharing options...
dennersten Posted July 17, 2016 Author Share #3 Posted July 17, 2016 Could you display a grey scale on her computer and photograph it; post the result here Great idea. Found this one. Her computer can't display the 6 lines to right (white) and four lines to the left (black) The lines are perfectly visible on my other computers. Welcome, dear visitor!

pico Posted July 17, 2016 Share #5 Posted July 17, 2016 (edited) Did you try the hidden advanced options in System Preferences > Displays > Color > then option-click on Calibration ? If the little box [ ] Expert Mode is not checked, then check it. That adds a few steps including Gamma adjustment.

Exodies Posted July 17, 2016 Share #7 Posted July 17, 2016 Advertisement (gone after registration) That's a lot missing from the high end. I think you should go back to the Apple shop; my iPad isn't like that. Quote Link to post Share on other sites More sharing options...
dennersten Posted July 17, 2016 Author Share #8 Posted July 17, 2016 I want to avoid that as far as possible. I have a long drive to a repair center and I can't afford to be without the computer. Could it really be a hardware problem? I thought it was very binary. Either the graphic card works or not. I didn't think it was possible that the card could work half good as in this case?

pico Posted July 17, 2016 Share #9 Posted July 17, 2016 I agree with Exodies. None of our many home Apple products does that. Quote Link to post Share on other sites More sharing options...
pico Posted July 17, 2016 Share #10 Posted July 17, 2016 If you look carefully some of the smudges are artifacts off-set from the subject. Others appear to be random. Frankly, in all the time I've used Apple (since 1985), and all their monitors I have never seen this before. Very sorry I've no answers. Oh, could your wife have added some graphics program that messes with the monitor? Quote Link to post Share on other sites More sharing options...
pico Posted July 17, 2016 Share #11 Posted July 17, 2016 (edited) Did you try the suggestions in the following link to RESET the SMC controller (if relevant) and PRAM? http://www.macrumors.com/how-to/reset-thunderbolt-display-smc-nvram/ Edited July 17, 2016 by pico Quote Link to post Share on other sites More sharing options...
Manoleica Posted July 17, 2016 Share #12 Posted July 17, 2016 If it's that new call Apple, they do have a Replacement Shipping Policy.. I have used it..It works.. The Store should exchange it on the spot if it's a faulty Video card or Computer.. Quote Link to post Share on other sites More sharing options...

Oh, could your wife have added some graphics program that messes with the monitor? The smudges appear to have been produced by the graphic artist to separate the three figures from the background; it seems to be work in progress. Altering the gradation such that all values below about 230 are rendered as black will reveal the application of "brush strokes" in parallel to the contours of the figures. 2 Quote Link to post Share on other sites More sharing options...
pico Posted July 17, 2016 Share #14 Posted July 17, 2016 (edited) Good call, Pop, but how do we explain the grey-scale issue? I call for an investigation of any new software installed after new, then a total reset of the system parameters as described above, and to repeat below. http://www.macrumors...play-smc-nvram/ Edited July 17, 2016 by pico Quote Link to post Share on other sites More sharing options...
pop Posted July 17, 2016 Share #15 Posted July 17, 2016 I don't know enough about Apple computers and their color management; therefore I have no explanation for the strange behaviour that it appears to show values from 32 to 230 only. I have calibrated both my Linux laptop and my iMac using the Huey color calibration tools, and the grey scales are quite satisfactory on both.

new2leica Posted July 18, 2016 Share #16 Posted July 18, 2016 In System Preferences, in the Systems section, open Accessibility. Under Setting on the left hand side, select Display. Is the Enhance Contrast slider pegged left? if not, move it over. 2 Quote Link to post Share on other sites More sharing options...
250swb Posted July 18, 2016 Share #17 Posted July 18, 2016 I think it's a basic calibration problem, one computer isn't calibrated, the other is calibrated better. So work done on the first isn't showing up the artefacts left behind in removing the background, but show the image on the second monitor and there they are. But the mid tones may come back if both monitors are calibrated, or alternatively good mid tones may have simply been a trick of a badly calibrated monitor in the first place. For example too high a contrast of the monitor would show better mid tones in the attached image, but it would also bleach out the background, hence not seeing the pale artefacts. Time to start again from scratch because for any photography or design you need to have a known baseline and calibrating the monitor is the first step, and if the MacBook can't be calibrated think of using another separate monitor (if that's possible with Macs, they are hocus pocus to me).

Jed Orme Posted July 18, 2016 Share #19 Posted July 18, 2016 Wow!!! This actually did it! It solved the problem! I am so grateful! I had no idea about the function. Never ever clicked the accessability button. Thanks all for your support and ideas!! I've been using Macs since they first arrived on the scene, but also was not aware of this setting. So I checked mine, & sure enough it was also not all the way to the left (this must be the Mac default). While I am certainly sorry that you had this problem & had to go through all of this to get it resolved, I am grateful that it will benefit others like myself. And can add that as an avid reader of Henning Mankell's books about Inspector Kurt Wallander, I have come to know a bit more about Skane & that part of Sweden where you reside.

Thanks so much. 1 Quote Link to post Share on other sites More sharing options...
