El Capitan: Screen text looks blurry and jagged

someone who wrote in here yesterday complained of the same thing. When I saw a screenshot of his System Preferences> display he had th brightness of his mac set to maximum, this caused me concern as this affects the life of the display. So if you have the brightness up high turn it to about half way.

i got him to run the screen calibrator from System Preferences>Displays>Color you will see a Calibrate button, press the option/alt key while clicking calibrate

and you should enter the calibration screen, click the expert mode button, and then continue and follow the on screen instructions.

hopefully this helps.

as mentioned above I think the brightness is set too high, 90 as you say has the backlight too high affecting the screens longevity.

turn it down to about 50 and try the screen calibration process from System Preferences>Display>Color press the alt/option key whilst clicking on the Calibrate button, then make sure expert mode is selected then follow the on screen instructions.

I had this problem too and I have found a fix that worked for me – so I am posting in case it helps someone else out, too! I had the same issue when I first purchased my external monitor (Acer K272HUL) and at the time was running Yosemite. The issue came back when I upgraded to El Capitan; fortunately, following these instructions did it for me:

Good luck 🙂

I am jumping into this thread to post a similar problem, but while running on a Mid 2010 27 inch iMac running OS 10.11.2. The worst offender is the latest version of MS Word (v. 15.18). I have the same doc open in that version as well as 14.6.0 (from Office 2011) and the older version renders much more smoothly. Turning off LCD smoothing in the system prefs. changes nothing.

HI

I have also samsung monitors and my solution was: On the monitor itself there are buttons, click on the menu button, after that just go to picture, sharpness and put the sharpness down, go to about 50%. It helped me so I'm 90% sure it does work with you 2. Reply to me if it has worked.😉
