Question: 10.9 (Mavericks) External Display Problem

Recently I made the upgrade to OS X 10.9 and now I start to having problems with the resolution of my sceen. I have a LG Flatron E2250V and it work perfectly in OS X 10.8.3, the recomend resolution for this display is 1920x1084 but right now the system only give me 1600x1200 option, thereby is in a wrong frecuency for my screen.


About 3 month ago I try to upgrade the sistem to OS X 10.8.4 and I had the same problem.

MacBook Pro, OS X Mavericks (10.9)

TheSmokeMonster,


Sadly resetting the PRAM doesn't work.

Was the first thing I tried.


Many people was waiting during OS X Lion to this fix, it was fixed in Mountain,

really ridiculous. Maybe this time we need to wait one year again to use just an

external monitor.

I have an LG2341 connected via a Rocketfish Thunderbolt to VGA connector. The max resolution supported only gets picked up if I have the monitor powered on first before I attach it to my MacBookPro (mid 2012). If I connect it and then power it on I only get default/low resolution options.

From all the things that could go wrong I never expected this was going to be one fo them!


Even my third DisplayLink USB monitor is up and running, yeah with terrible performance but I can live with that I guess.


My monitor is connected via DIsplayLink to VGA adapter, 1920x1080 is selectable with ALT menu but the screen has an horizontal offset and the image quality is very bad. Auto Adjunsting the image via the Monitor settings doesnt doesn't seem to solve this.


😕
