V1.8 Alpha issue: no resolution choice on rotated monitor

pdimarzio · 03-07-2012, 12:52 PM

Per request I'm reposting this on a new thread ...

MacBook Pro 2.66GHz Intel Core 2 Duo, 8GM RAM
OS X 10.7.3
Acer 2216w horizontal driven by mini-display port
Acer 223w vertical driven by Iogear USB adapter

When I installed the Alpha both screens came up fine, the rotated display driven by the USB came right up in proper orientation - even remembered the background picture. However when I moved a text window to the rotated screen I noticed the resolution was very poor. In the past I've used the max resolution of these monitors (1680x1050 horizontal, 1050x1680 vertical). With the new v1.8 driver there is only one option returned: 1200x1920 (which doesn't seem to be a native res for the Acer, as it doesn't show up in the list for the horizontal monitor).

I've also found that the horizontal monitor does not get driven when I bring the machine out of sleep. Since this is the main window, with the logon screen, I have to shut off both external monitors, lift the cover of the MBP to logon, then turn the monitors back on. Of course everything gets quite confused, all the windows switch from one monitor to the other - then back again - and all need to be resized.

This is really not usable and I'm going to have to uninstall the driver and hope for a better version - I'll leave it on temporarily if there's any data I can gather for you (but you'll need to give me instructions on how to gather it). Thanks.

Thanks for your report.
You could use the tool here http://www.displaylink.com/support/ticket.php?id=269 to gather information and post the output zip file. Thanks

Thanks for the link to the tool, Christian. The file is attached, hope it is useful.

Of course the displays did properly wake this time - after failing the previous 3, go figure! But the resolution problem remains.

Has the debug file helped at all? Wondering if there are any thoughts as to why I can only get one resolution on the monitor, thanks.

I too am having the same issue where I am using a rotated vertical display and the only option I have is 1200x1920 - which is not native to my monitor apparently so the text is unreadable. I upgraded to the alpha 1.8 in order to be able to rotate my display again in the latest OSX update.

Is there anything I Can do to force a resolution? Any feedback I can provide as well? I'm using Veiwsonic VX2450 series monitors.

Thanks!

The current workaround we implemented for the OS bug introduced in OS X 10.7.3 makes available some resolutions but not all the resolutions supported by the display.

On most monitors the available resolutions include the native one, but depending on the information the monitor is returning to the OS the native resolution might be missing.

The issue does not seem to be fixed in 10.7.4. We are looking into improving the workaround but at this stage don't know if it's possible and how complicated it would be.

I know this is not a great answer but it's where we are at the moment. We might spend months developing a solution for then just seeing a fix in an OS update..

Cheers,
Carlo
