My external monitor was fine in 10.9.2 and below, it runs at 2560x1080. After the update the update my whole screen was blurry. I checked the rosolution and it still says 2560x1080 and my color profile is still in place.

I have samsung 27'' monitor and it is also not working after 10.9.3.. I can't freaking believe it!!!!!!!!
Every apple update is a fuc*ing new problem to solve. That is so frustrating
I need help!!
Same issue here... 27" Asus ProArt 2560x1440 was blurry after my update but I had to update my setting on my monitior which fixed the issue.

Before update (OSX 10.9.2), lovely crisp photographs, text, colours etc, after update to OSX 10.9.3 everything is all out of focus, blurry text in particular. Terrible, just impossible to read anything.
I have tried a few things like SwitchResX and other cable inputs but have had no joy. Have re-installed OSX 10.9.2 and will for go this update.
after reading ed.rdm´s post i have tried to change the sharpness settings on my Dell U2713H.
this fixed normal working.
i am glad that i do not have to photoshop many things ... i think this sharpness setting of the monitor could kill any smooth gradient image area.
conclusion ... office workers may adjust this problem by setting the right sharpness setting on the monitor.
photoshop users should not apply this update!
Yeah don't update if you need to edit photos or build interfaces... looks like garbage. Seems like Apples attention to detail has dropped with the Lion release. I have never had this many issues with OS X
Unbelievable. My DELL 27" now looks like blurry garbage and worst of all, the resolution is stuck at a lower rate and I can't change it. How am I supposed to do my graphics work? This is disgraceful Apple. Post-Steve Jobs, you have become a shadow of your former selves. This is the last straw. Thanks... now I have to spend my weekend completely reinstalling my entire system and downgrade to Snow Leopard. Never, ever, ever.... run an upgrade from Apple again. Shambles. Total shambles!
Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.
hello simon,
i always see this frustrating answers of the proceed of big companies making a operating system.
customers seem to be a testing-objects.
versions of the system are going up ... and up ... and up.
they can not check any configuration - in real speech: they are humans!
and if ever testing is done - there are humans with various hardware.
if i were in anyway responsible for developement of software-features i would think before i do it...
nevertheless - just adjust your sharpness on your display and it is done.
if you are a phtoshop-worker ... i would understand you telling apple software-engineers are failing her destination 😉
Hi, same problem here with a Dell U2713H connected via mini display port...
Can someone explain me how to downgrade to 10.9.2 ?
I tried downloading the 10.9.2 upgrade from apple but it won't allow me to install it
Thanks and I join the hate of apple for doing this to us !
One more question: how to set the sharpness on the Dell U2713H ? The drivers are only for windows and there is no manual buttons for doing this.
Thanks !
Dell monitors usually (not always) have an on screen menu with sharpness options. You get to it through the buttons on the bottom of the monitor.
I sent the feedback after confirmation I was not alone in this; after it-netzwerker's post.
No buttons on mine. Currently re installing 10.9.2 from time machine. Thank you apple for making me loose my day...
Every Dell monitor has adjustments somewhere, I recommend looking at your instrution booklet in case they are just on an invisible touch panel like mine.. or bottom, or back. The buttons allow brightness and contrast adjustments; it may be useful in the future.
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.
Anyone else have a blurry external monitor after 10.9.3?
