Q: 10.10.5 (14F27) loss of monitor resolutions
Problem: screen resolution disappeared after Yosemite update 10.10.5 (14F27) on August 21
My system configuration:
MacBook Pro (Retina, 13-inch, Late 2013)
Graphics Intel Iris 1536 MB
External Monitor: LG222WT (resolution: 1680x1050)
Questions:
Did the recent update include a driver update?
Is anyone else experiencing this and know of a fix?
I have no idea how I can add/see additional resolutions.
Description:
For two years, my monitor and laptop configuration has been fine. Now, after recent update 10.10.5 (14F27), my external LG L222WT monitor defaults to 800x600 resolution, because it's native resolution of 1680x1050 is no longer available.
This problem can't be solved by opening the Display Preferences, then option-clicking the scaled radio button, because the 1600x105 resolution simply isn't in the list, which is limited even in its expanded form.
MacBook Pro with Retina display, OS X Yosemite (10.10.5)
