Mountain Lion Problems

[MickM]

I haven't seen any of the login screen problems yet, but boy am I seeing screen flicker under mountain lion. It's possible that me not seeing login screen problems is because my main screen (the one anointed to have the menubar) is not a displaylink controlled screen. In addition to the screen flicker, whenever I invoke mission control the little window containing the image of the DisplayLink monitor is just messed up. In case it matters, I'm running 10.8.1 on a retina 15" MacBook Pro. I'm really looking forward to the next update for DisplayLink - I check every day for it!

I'm starting to get just as frustrated as everyone else, I was just lurking in these threads because the problems I have been seeing other people have been seeing.

However I now have to add another voice to the chorus.

I use a DisplayLink adapter to drive a monitor while I am at work, outside of work I do not use a DisplayLink Adapter and I do not have any issues. At work, I have flickering content inside of browsers, I never see the box to enter my password when my screen saver activates, thankfully I've just been able to type blindly. Also I get the occasional kernel panic.

I'm at the point where I will not be able to recommend any DisplayLink product to anyone.

Are you implying that outside of work you use a DisplayLink adapter and mountain lion and you do not have any issues?

I fixed the wording in my post to make it a bit clearer. I do not use a DisplayLink Adapter when not at work.

I'm in the same boat as Stephen... frustrated and yeah.. kind of need my second monitor to work since this is for work. I may just have to save up for a thunderbolt display from apple to "resolve" my issue.

In my case, besides grey login screen, it crashes finder, preview, the whole office suite and even itunes.

Please let me know if there will be an updated driver soon, so I would return the product.

I am running a business and bought 12 of these to use with our macs. This is complete unacceptable. Just like what everyone else is saying once i install the drivers everything else starts crashing. This needs to be fixed now. I have invested over $500 in this hard ware, and I am not about to have to pay for restocking fee. Please fix this problem or send me a check for the full amount of the product. I believe that I wouldn't be the only one ready to seek legal action against your company. Please just simply fix your product so we can use it like it is advertised to work. Thank you

I recently went from Snow Leopard to Mountain Lion. Previously, my monitor connected via DisplayLink correctly set the maximum resolution of my display to 1920x1080. It now incorrectly sets the max resolution to 1280x1024. The highest resolution I can set the monitor to without distortion, due to the wrong aspect ratio, is 1280 x 800.

My monitor is an Acer S231HL

As a fellow software developer, I urge you to create a tool for advanced users that would allow a person to input the maximum resolution and refresh rate manually. I know this is probably easier said then done.

Hi there,

• Mountain Lion 10.8.2
• Mid 2009 Macbook Pro 8Gb 2.53 Core2Duo
• 9400M-256MB
• VERTEX4-256GB
• 15" macbook 1440x900
• 24" plugged into mini displayport 1920x1080
• 27" plugged in usb hdmi 1920x1080

I got http://www.amazon.co.uk/Cable-Matters-Plated-Premium-Adapter/..... this today, it didn't seem to work without the driver...
so I downloaded the latest Mac driver

I saw the warning for Mountain Lion, awesome

Installed driver, rebooted, had to unplug and plug back in but it worked. Showed up in Display Prefs as the identified (with model info etc) 3rd monitor, works great with Arrangement tab, and made the usb 27" my main monitor by moving the top taskbar over

However,

• laggy performance on usb monitor (just about bareable, but really noticeable when u have two great performance monitors either side)
• sometimes mouse freezes on the screen, but I can still move it about (like taking a snapshot of just the pointer)
• also I have to sometimes make something on the designated screen happen for it to "activate" , e.g. drag a window onto it, after logging in. (As it's set as my main monitor, I cant see the login screen too) - but its a BenQ monitor that does take pretty long to start up so will confirm in more tests tomorrow
  
• but no lag on other screens
• and no crashing programs (had ubuntu VM open, chrome, skype, chrome, preview, itunes, mail)

I dunno how many days I've got till I can return it, which i will do, as i didn't buy a decent second monitor for it to lag, but I hope either Apple or the developers make it work with all the known issues, and I guess general performance, before then! You can't even get Lion in the app store, which I would do, you know, just to make use of my second monitor or something stupid, so you gotta ring apple to get a special code, great, cheers for not mentioning that on your page

Save all of us a phone call, ring one of your apple cronies and work together to update the driver before they update OSX ? how do we even know that 10.8.3 will fix it? how do YOU even know that 10.8.3 will fix it? what if apple doesnt care about your hardware? i know who does care. the people buying it.

Lag is caused by USB bandwidth limitation.. there is no way to solve it other than a hardware / port upgrade.
