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

May 23, 2014 3:30 PMby Zak Adelman,People are not stupid for wanting it fixed, especially for the people who want the 4k update than came with 10.9.3. I can easily roll back but others can't and don't have the cash to pay someone to fix it for them at often $80-$100/hr. It is not like thay are complaining about a beta not working.
Telling people to "turn on brain and decide" is the same as calling them stupid so you can stop that now.

May 25, 2014 12:10 PMby it-netzwerker,hello zak,
i never wanted to call anyone "stupid". - sorry - perhaps you (and others) misundersood what i wanted to tell ... and i was seriously texting this answer in the wrong way.
we are all beta-testing a new update called 10.9.3!
if our loved system-developer "apple" deside to change basic behaviour of our loved machines - then i would wish they gave us a little hint of what they have changed.
and: if possible give us some answers to the questions we have after a update.
for me 1 week with this annoying blurr-bug is a lot of time ... why they do not fix this issue!?

May 25, 2014 3:22 PMby Zak Adelman,I am thinking this is part of the 4K update to the video kext(driver). Everyone here seems to have a 2650x1440, except me at 2650x1080, and I heard somethig about blurring on 4K in the past to make it look decent. This could be a glitch caused by an "odd resolution" (not 720p or 1080p) and non-Apple. They did tell us the video was being upgraded in some way which would include the kext.
I will linstall 10.9.2 in Parallels and see if I can get the kext file to do a video downgrade. I am too busy to do a full downgrade at the moment.

May 27, 2014 12:19 PMby Alan Hogan,I am on a Retina MBP using a big external Dell U3014 monitor at "best for display" resolution. I noticed this blurriness right after upgrading to OS X 10.9.3 as well. Switching color spaces had no effect for me. Instead, the solution was to use the monitor settings (with the actual buttons on the display itself) to set "sharpness" to 50%. Before updating OS X, "sharpness 50%" meant white glow around text and artificially enhanced contrast — basically HDRing my display, which is highly annoying and undesirable to me (I work as a front-end web developer and sometimes as a designer, and I am also a photographer, so this would be extremely misleading as I work). I had thus set it to 0% sharpness. Post-10.9.3, "50% sharpness" means "don't blur the screen OR artificially enhance it." So weird!

May 29, 2014 2:29 AMby Dommy B,Same here! Grrrrr! In the middle of an important video/graphic job, updated to 10.9.3 and boom! BLURRY SCREEN!
Im on a DELL U2713H.
Please fix Apple! This will no doubt be affecting many colour/pixel critical users around the world. And its just annoying for everyone else! I thought I needed glasses when I turned it on!
ARGGHH!

Jun 2, 2014 11:42 AMby eselat,thanks for this thread !
same problem here (in Vienna, Austria)
MCP early 2011 + Dell U2713H (Displayport via Thunderbolt)
dell sceen got all blurry after the update
so i changed the sharpness (as proposed here - thx!
mine looks "normal" again at "40" (but makes me insecure about true sharpness of e.g. photos)
I hope that a proper re-calibration will fix the issue
as was also proposed here.
ps.
i noticed that the blurriness appears
only if resolution is set higher than 1080i
wouldn´t that speak against the theory
that apple just chose another mode of "displaying sharpness" for highres monitors?
(50% = new average = former 0% sharpness)

Jun 3, 2014 2:30 PMby anothersmurf,See <http://jeradhill.com/os-x-10-9-3-issue-fix-blurry-image-display>. I have a Dell monitor; the solution was to increase the sharpness in the *monitor's* settings (not the OS/Control Panel).

Jun 21, 2014 3:52 PMby Zak Adelman,I just got a Samsung U28D590 display, it is 4k and running at 30Hz but even at 60Hz at lower resolutions it is blurry like my other monitor.
Now, even at 60Hz, and despite it being 1ms, there is ghosting caused by the sharpening (it matches the sharpening color exactly) because it has to be set insanely high, 68%.
This blurriness needs fixing badly, it is painful seeing the artefacts caused by hardware sharpening.

Jul 5, 2014 2:37 PMby Zak Adelman,It didn't fix mine.
I am not aware of either high-end Spyder or Colormunki having a sharpness detection setting but it wouldn't be in the profile if one of them did, it would work the same bad way we are stuck with now, sharpness after the fact in the monitor's settings causing artefacts. The artefacts are not a bad side effect, that is how it "fixes" the blurry video, something that would not happen if it was done internally before video hits the cable out to the monitor.

Jul 21, 2014 11:05 AMby ilex1,I'm looking at getting the ASUS PA279Q 27-Inch Screen LCD Monitor, but have been leery due to the number of complaints from other with problems with blurry text on MacBook Pro Retina connect via Display Port. Many sources on the internet point to the way Mac OX handles EIDI settings. One solution I've come across is here. http://www.ireckon.net/2013/03/force-rgb-mode-in-mac-os-x-to-fix-the-picture-qua lity-of-an-external-monitor Not sure if this works, but it many be worth a try. Meanwhile, I'm on the fence about getting an external monitor.

Jul 23, 2014 5:32 PMby Njma42,No, it is still broken. I've tried all the suggested solutions, and nothing works. No amount of SMC/PRAM resetting, color calibration, EDID editing, or anything else made any sort of difference at all. For the time being, I set the sharpness on my monitors (Dell U3014) and will just deal with the artifacts until Apple finally fixes this bug.

Jul 23, 2014 11:32 PMby quarkdoll,Please file a bug at https://bugreport.apple.com -- it's our only recourse to hoping that Apple addresses this (? in parallel to them steamrolling ahead with a buggy Yosemite ?)
