Elind2 Level 1 Level 1

The screen goes slightly blue when open image-applications. Like VLC, Photoshop, Music DAW's. And i dont know why. I read that there is a few people that has encountered this as well. But i cant find a solution to what it is. Guessing it is mountain lion has a glitch somewhere.

Anyone else here having these issues?

Im on a mac book pro 2011 i7 quad.


MacBook Pro (15-inch Early 2011), OS X Mountain Lion (10.8.2)

    try Preferences - display - color - show profiles for this monitor only - select profile that will last. Close preferences. Should help

    Also it can be slight difference between integrated and discrete GPU. It is uncurable and normal, if difference is _slight_

  • Elind2 Level 1 Level 1

    No i tried that already. Read that somewhere else to.

    I tried all the profiles but noon is working. I mean, as soon as i open photoshop or VLC or Reaper, it still turns slightly blue...

    try preferences - energy saver - disable automatic graphics switching. It will force discrete gpu, check, will it solve problem. If so - nothing you can do, it is difference between integrated and discrete cards. Theoretically it can be cured with videocard LUT correction, but it is question of Apple update.

    You're experiencing the same thing that I - and a handful of others - experienced. What happens is that when you open an app that is dependent on the discrete GPU your screen will take on a bluish tint. You can verify this by downloading gfxCardStatus. If you set the GPU to integrated only, it won't display the blue tint. Only when you're running discrete only or dynamic switching will the problem occur.

     

    My blue-tint problem just 'went away' - I didn't do anything to try to fix it. It only happened after I upgraded to Mountain Lion. Other had some success by resetting the SMC. The problem affects just a handful - literally about a dozen that I've read of here and on the Photoshop forums - that it doesn't seem to be related to one model. The only thing in common is Mountain Lion.

     

    Download gfxCardStatus and see if you can run on integrated only for a bit. Also try resetting your SMC. I know why the problem occurs - just not enough info to tell you how to fix it.

    No that didnt do it. It just made the screen the same blueiness ALL the time instead of when i open the applications it got blue with before..

  • dmdimon Level 3 Level 3

    that exactly did it - now you have only discrete GPU ("bluish" one) enabled all the time. You can correct it in calibration section of monitors preferences.

  • Elind2 Level 1 Level 1

    Do you mean calibration setting in "colour"? Calibrating the screen manually?

  • dmdimon Level 3 Level 3

    yes. color temperature - move it a bit, it will help

  • Elind2 Level 1 Level 1

    Alright, have to go out for a bit, ill check when i get back.

    Thank you for the help this far.

    That won't work - it's not a problem with color calibration and 'calibrating' to try to 'fix' the GPU switching will not work. It's a problem only when the GPU switches from integrated to discrete - like I said, about a dozen people that I know have experienced this.

     

    The only thing that you can try - and I'm not saying that it will work (as I said, my problem just 'went away') is to reset the PRAM and the SMC. If this doesn't fix the problem (and I doubt that it will) the only thing that I can suggest is patience. The problem won't persist - and I don't know why.

    it will work with forsed discrete GPU. zap PRAM/SMC will not help.

     

    Also it is possible to have 2 profiles.

    Furthermore, it is possible to make an applescript (not sure here) / shell script that will monitor in background which gpu is working and will switch profiles accordingly.

    No, it won't - I've had the problem that the OP describes.

     

    zap PRAM/SMC will not help.

    Maybe not - it's helped others, though.

     

    Also it is possible to have 2 profiles.

     

    Yes, but the profile isn't the problem. You cannot calibrate for this probem - I know. I've had the problem and been in a handful of discussions with others who've had the problem. Calibration doesn't solve it.

    /offtop

    I have no this problem, but.....

     

    1) OP have 'slightly blue' feeling when switched to discrete GPU. Why this can't be corrected with profile _specifically_ made for discrete GPU color tint compensation?

    2) there are ways to get a clue which GPU is running from shell script

    3) there are ways to switch profiles from shell script.

     

    So why problem can't be (not solved, but) visually cured with two profiles (for integrated and discrete GPU) and cron-runned shell script for automatic switching of that profiles?

     

     

    I may be wrong about zapping PRAM/SMC. But if so - it is some exotic second-order bounded thing. Good if it helps.

  • Elind2 Level 1 Level 1

    How would i do when i zap the pram/smc?
