Q: 10.9 (Mavericks) External Display Problem

The 10.9.1 Maverick update did not fix the problem with the Quato 242ex Monitor. The native resolution of 1920*1200 is still not possible. No ALT key or Mini Display Port solves the problem. As an graphic-designer and illustrator I can’t work with this wrong resolution 1080p or 1080i because it has the wrong proportions.

When you solve this problem?

Why we don’t get a «expert mode» in the display menu to use all resolutions possible for those who knows the native resolution? Automatic resolutions only make sense, when they are correct!

With OSX 10.6 it works, with OSX 10.7 it works, with OSX 10.9 it did’nt work. Why?

I confirm this statement by 100%!

Same Situation here.

Chances are that your setting is on scaled try changing it to "Best built for this display"

Hello superbiketyty

Thanks but no chance. «Best built for this display» just uses one resolution from the «Scaled» list. In this case it’s 720p – a really bad choice for «best build». It’s far away from 1920*1200.

I’ve contact the apple support today and they did not solve the problem until now. I should get an answer next week, when a coder attended to the missing resolution. Hope they fix it.

Greetings from the snowy mountains

I am having a different problem: the external display does not work in some devices such as some Hitachi projectors.

OSX 10.9.1 Mavericks multiple displays stop working.

I had a TV connected via mini display to VGA. It worked for month on 10.9 on a new Retina MacBook Pro 13 it worked for a while 10.9.1, after it powered down one evning it did not worked again. Now there is no signal going to the TV. Can anybody help?

After 10.9.1 Mavericks update my two 2560x1440 monitors work well in the standard (landscape) mode but do not work correctly in the rotated (portrait, pivot 90 degs) mode.

The only resolution available for 90 degs mode is 800x600. What is amazing, the available resolutions for 180 degs mode are also wrong (1920x1080 and 1360x768 for Dell U2713HM and 1280x720 for HP ZR2740w).

In Lion both monitiors worked fine in rotated mode.

On the other hand my third external monitor (Samsung SyncMaster 2693HM, 1920x1200) works well in both standard and rotated mode.

**MacbookAir4.1 with miniDisplayPort–DisplayPort cable (changing to miniDisplayPort–DVI-Dual-Link cable does not solve the problem), and monitors: Dell U2713HM, HP ZR2740w, Samsung Syncmaster 2693HM)

I have not been able to get my third monitor to work since upgrading to Mavericks 10.9.1. My MBP is 13" mid 2009. I run my second monitor through the mini-DVI and the third monitor through a VGA to USB adaptor (Diamond-Display Link). They both worked fine prior to the software update. Any suggestions, other than restoring the old software package?

Thanks

I have also experienced problems when using miniDisplayPort-to-DVI-Dual-Link cables  in 2 of 3 high resolution monitors I tested. One was snowing and second stayed completely black; I did not care for it as my primary concern was to achive right resolution in the rotated position. So I am not surprised. Try another DVI cable or, better, switch to using another port in the monitor (DisplayPort, HDMI, VGA, whatever available). As far as USB monitors are concerned, my fourth monitor (Lenovo ThinkVision  LT1421wD 1366x768) works well under Mavericks 10.9.1 when connected via USB port with  the latest DisplayLink_MacOSX_V2.1.dmg.

Same problme here with a Quato 244ex. No chance to get from 1920x1080 to the native 1920x1200. Screen is streched vertically. So - many hours and headaches later  - I went back to OS 10.8...

But I don't think, it's a specific Quato problem.

And - dear Apple: This is NOT professional, no, you act like rookies!

I doubt Apple read these forums, they are just for user to user communication.

If you want Apple to take note, you should send them an official feedback report:

I had a similar issue with resolution on an external Samsung monitor. I finally gave up and went to resolve another issue - the dual menu bars.  After a reboot, surpise, all the desired external monitor settings were back and I can again utilize my full external monitor.

Changing the dual menu bar settings does not solve the problem of wrong resolutions supplied by the system for vertically oriented (rotated) high-resolution monitors.

I have 2 VGA monitors connected via Thunderbolt and USB with a Startech

USB2VGAPRO2 adapter. As soon as I downloaded Mavericks, the second monitor would not work. Common problem, I gather. However Startech has a new driver. I downloaded it and everything is working as before. Thanks to Michael Schoefeld at Startech Canda for emailing me that this was out. great service and a very good product.

I have two USB2HDMI adapters and a third monitor on straight Displayport cable. The only startech driver for the USB2HDMI adapter was dated October 2013.

What was the date on your updated driver?
