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)
I have the same problem even with my Philips E-line monitor. The best resolution that i get is 1280x1024, while before the upgrade it was correctly 1920x1080..
Really Apple, really ?
Again playing with my monitor max resolution in 2013 ? ... this is the most advanced OS in the world ?
DELL 3008WFP, working great in Mountain Lion, 1920x1080 before, 1600x1200 (not widescreen now)
Using my 30€ !! APPLE macbook DVI adaptator for nothing.
Why Apple always do the same stupids things every update ?
I was fighting with this error a lot before, in mountain lion was fixed,
now the issue is here again.
How long do we wait to fix this ? ... really serious fail here.
Really frustrated.
I have the same problem. 1280x1024 resolution was not display list.
May be Maverics got problem of display setting.
How to solve this problem?
Temporarily I've solved this issue, Using SwitchResX App. 10 days trial version.
try a PRAM reset http://support.apple.com/kb/HT1379
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 dont know if this help but the last two versions of OS X Mountain Lion 10.8.4 and 10.8.5 had the same problem. I had to donwgrade the system to OS X 10.8.3 with the time machine to solve the problem and now I´m waiting for an answer, to try to update to Maverick again. THIS IS REALLY SAD
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.
Try holding the alt key down when selecting "Scaled" in the display settings screen. More resolutions appear in the window then.
Yeah, this ALT thing works, .... really intuitive : (
The ALT thing worked for me!
I also had a problem with my Planar PX2611 monitor after upgrading to Mavericks. But Mongyee recommended SwitchResX, I tried it and it worked. It was an $18. fix and well work it.
Thanks G Webb !!
I can select 1280x1024 resolution of my display.
Thanks again. 😟
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.
