Q: Anyone else have a blurry external monitor after 10.9.3?

That said, downgrading is probably your (really everyone's) best bet when this problem cops up since hardware sharpness causes other issues that effect dealing with graphics and photos. I use Illustrator so I have issues with line accuracy (it adds a white line around lines to sharpen them and causes banding) when sharpness is on. I will give this a week and if there is no update I will follow your lead and downgrade s well. I am using my 15" built-in monitor (retina MBP) to check when I think I am done with part of a graphic's linework or gradient.

May 16, 2014 7:00 PMby Zak Adelman,I tried contacting Apple Care and tried reinstalling 10.9.3, installing 10.9.3 from scratch, resetting PRAM, resetting SMC and none of them fixed the issue so don't bother trying those.
The issue was esceletad to the department that would handle the update to support these screen resolutions.

I think this goes to prove very little testing was done prior to release. This is what happens when a new new OS is "free". Apple adopts the Microsoft approach to testing - very minimal if any! Throw it out there, let the public find the bugs and report them, then fix them. So it's:
1) free of charge
2) free of beta testing
3) tested for free
Oh boy, is this what the future holds for our once stable and trusted operating system? I shudder to think.

May 17, 2014 12:43 PMby adriangp,I might have a clue to what is going on here....
I have a Dell U2413. Prior to Mac OS X 10.9.3 I noticed a strange difference between using this monitor with a Windows-based PC and my Mac.
On my Mac the display looked perfectly sharp with the Dell built-in-display sharpness setting set to 0. i.e. My mac was talking to the monitor in a way that meant the image was already sharp at the sharpness setting 0. There was no option to soften the image because you cannot go below 0. Any sharper and it looked stupid!
On my Windows machine (with official drivers installed) the display looked horribly blurry at a built-in-display sharpness setting set to 0. But when the sharpness was increased to say 70 it looked very good. This allows the owner to adjust the sharpness to their own preference.
Since upgrading to 10.9.3 on my Mac my display suddenly appeared blurry. I have since discovered that my display should be set somewhere around the 70 mark to get a sharp image.
I imagine along with the new 4K display support Apple have changed the way the OS talks to the display over displayport to work like the Windows counterpart (and possibly more like the display manufacturer intended).
This certainly makes it more convenient for me when I switch between my home Mac and my work PC!

May 18, 2014 5:01 AMby styleisimportant,This strange solution/tip from Cna93 in other thread worked for me! (on DELL U2713HM)
QUOTED from https://discussions.apple.com/thread/6223524?tstart=0
Go to system preferences ----> Displays-----> color tab run a new calibration , restart then go to the settings again and choose the old calibration and remove the new one

May 23, 2014 2:35 PMby styleisimportant,I first thought solution (calibrate) was working. But I'm looking at mostly blurred letters, or too thin letters. It is really impossible to read text comfortable on DELL u2713hm connected to MBP 15" retina late 2013 (10.9.3) with mini display port. I cannot go back to previous system.
Apple please fix this: it was perfect on 10.9.2.
Thanks.

- turn on brain and decide:
1.:
do you having user problems? then adjust your monitors sharpness (how to adjust jour monitors sharpness is a turn you will get with your monitors onscreeen-menu) ... or switch back to 10.9.2. to go back to 10.9.2 you have to search for a (apple)-consultant - yes! it will cost you some amount of dollars/euros/orwhatcurrancy to fix it - ask him ... it is possilble!
i would estimate about 2.5 hours appending upon the data to transfer ....
it is your decision (or what do you think these consultants could bring back your productivity !?)
2.:
ist it urgent .... you are a productive user!?
today i was asked about the decision to make a update of the system ... i really was in a "splitscreen" and told my customer: please wait 3-4 weeks to make it ... otherwise ask me ( i am a consultant without apple´s consultant network - i dont want to be a "slave of a system" ) directly via mail or phone if you could update without any problems.
this to testify is the only way to become to a solution of your question ...
you need to have a apple/osx professional - right?
go get him.

Mirroring means that both your internal display and the external display will have the same image (mirrored!), consequently, both will show the same resolution.
The actual resolution is determined by the external display.
