Q: Mac OS Sierra 4K screen resolutions with Dell P2715Q (solved)

(original post completely changed)

 

After the upgrade to OS Sierra, Mac OS would apparently not correctly recognize my Dell P2715Q monitor, and would not offer the full list of resolutions.

A number of restarts have solved the issue - resolutions are fully available.

MacBook Pro (Retina, 13-inch,Early 2015), OS X El Capitan (10.11.3), null

    Well, I thought it to be solved - but it isn't. HiDPI remains an issue...

    I have posted another thread with more details in the Mac OS Sierra forum.

    Please file a Bug report so that Apple is aware _AND_ that customers care and want support for external monitors besides 1080p

    Thanks Bob

     

    I did exactly that. Lets see what happens.

    Maybe Sierra has significant changes under the hood, but what concerns robustness, I'm quite disappointed by that initial Sierra release... I haven't had to use so many force shutdowns and didn't experience such erratic behaviour in a while.

    Lets hope Apple will fix it.

    This isn't solved. But here is my workaround.

     

    • Turn on macbook and keep it open. Monitor is also on and plugged in via displayport.
    • Login.
    • When desktops appear on both macbook and monitor, shut lid to clamshell mode.
    • Monitor will have wrong resolution and options will not include scales hidpi modes that I used under el capitan.
    • Restart from top left menu.
    • Now log in and your will have previous resolutions and modes available.

     

    I use my macbook 13" early 2015 in clamshell mode with a 4k NEC EA244UHD professional monitor .   as well as mobile on the move.

     

     

    I really am disappointed by Apple's policy of denial and silence on critical issues. Remember the wi-fi issue that took months to fix... On devices with no Ethernet!

     

    Apple has nothing to lose and lots to gain by following the open transparent bug tracking followed by much open source (which Apple incorporates into macosx).

    Right, it isn't solved. I just can't edit my post anymore... it is in the wrong forum anyway, but when I had posted it, the Mac OS Sierra forum wasn't even available...!

     

    I know your workaround, I do sort of the same. Takes me 5-10 restarts a day to keep thinks workable. Please file a bug report bugreport.apple.com, so Apple knows about... I doubt they read the forums, which I find a pity.

     

    Let's hope Apple will fix this soon. Apple and displays, what a drama.

    I have filed a bug report.

     

    In fact I registered for the first time to do that. (And post here)

     

    I didn't get any follow up.

     

    Seriously - for a premium company offering a "pro" system ... the testing is worse than many £50k startups .. I wish I was joking.

    Apple has nothing to lose and lots to gain by following the open transparent bug tracking followed by much open source (which Apple incorporates into macosx).

    Commercial companies that promise something, create expectations that if not provided, result in problems (including problems that include lawyers).

     

    The developers that deal with bugs are not in a position to make any promises, because they cannot predict what will and what will not make it into a bug fix update, or a next release upgrade.  Often times they do not know at the start of a bug if it will be a simple fix, or if the code requires a major rewrite, or worse the entire infrastructure needs to be redone.

     

    Speaking as someone that has been involved in the development of commercial Unix operating systems (other fortune 100 computer companies, never for Apple), developers are never allowed to say when something will be fixed.  And when they mistakenly do say when something will happen, management tends to "Have a Talk" with said developer.  After that, said developer stops mentioning when something will be fixed, or giving too many details in a bug report.  And some bug reporting systems do not publish internal developer comments that can only be seen by other developers.

     

    Open Source is totally different.  If someone says it will be done by X, and then does not deliver, they often times do not have a manager to walk into their office and have that "Talk".  Then again maybe Redhat works differently (or other large companies contributing to Open Source), but I would bet that their managers would discourage them from saying too much in a bug report.

    Thanks for an considered reply.

     

    The key here is is that openness and transprency is incredible helpful, .... But isn't the same as making unrealistic or unwarranted promises.

     

    Many many serious and successful companies do understand that.
