Flash not supported on external display?

Hi,
With my MacBook, I use an external display all the time. It works perfect, exept that most of the 'in-browser' videos and all flash items (lots of them in recent websites) just aren't shown on the external display. So, whenever it happens, I have to drag the screen over to my MacBood display for it to work. Is this a driver issue? (external display is a Samsung SyncMaster 172v)

Very strange issue,
A screen is not aware of the content which it displays.
not sure what the problem is there!
So if you drag the window to the macbook screen the content plays?

T520 - Supports 2 external displays?

I was wondering if could inform me if my Lenovo T520 (Intel HD 3000 GPU) laptop supports 2 external displays (inc. internal laptop display).
So the setup would be 2 LCD monitors, one using VGA (currently attached) and the second one will be connected via displayport to DVI convertor. Is this setup up feasible or do I need to turn off the laptop display to make it work?
Any advice would be much appreciated!

The T520 doesn't have a USB 3.0 port, so just get a USB 2.0 version. Alternatively you can split the displayport signal between 2 external LCD to make them as one LCD.
For example if you have 2 x 24 inch LCD 1920x1080, you can get a displayport splitter that treats these 2 LCD as one LCD of 3840 x 1080. The advantage of this is doesn't use much CPU performance like the USB displaylink technology.

MacBook Pro not automatically recognizing external display

I have an ACER 2216W LCD display connected to MacBook Pro with DVI cable. When I first plugged the ACER display into MacBook Pro, the ACER started right up -- nice plug and play. I disconnected DVI to bring MacBook Pro to school, and when I reconnected it at home, I received a "NO SIGNAL" error message on the Acer. I sent the Acer to their tech support in Texas after receiving no support from Apple (in Canada) and it tested fine on their PC. (They do not support Mac). When I attach the display, or turn it on, MacBook Pro screen goes blue and comes back quickly, as if it is trying to id the display. When I push "Detect Displays," I get nothing. System Profiler is not showing an external display. Any ideas -- is there a start up command I can try? Thank you! My Photoshop homework is building up.

"Auth type not supported by External DB" error for web-auth SSIDs

Hello
We're having a problem with web-authentication on our 4404/WisM controllers since we moved to software rev 5.x (currently running 5.1.151.0).
With software rev 4.x our web-auth SSIDs would send the authentication requests to a Cisco ACS4.0 which would then authenticate the users against MS Active directory.
Now (with rev 5.x) the same SSIDs cannot authenticate users against AD, the error in the ACS is:
Auth type not supported by External DB
Found the following Cisco Doc regarding the problem: Cisco Secure ACS and Windows AD EAP/802.1x port authentication fails with the Auth type not supported by External DB error message - Case Number K24308566. Done a packet capture on ACS to see authentications coming in and the ones that fail with above error are using CHAP - from the Cisco documentation, MS AD doesn't support CHAP.
Any ideas on how I can get the web-auth working again with software rev 5.x ?
Thanks
Andy

my apologies - theres a setting under Controller - General for Web Radius Authentication. changed this from CHAP to PAP and its now working ok.

Flash not supported

I want to watch an instructional video on my Ipad 3 but it says Flash is not supported. What should I use to view it?

No Flash for iPads, iPhones, or iPods
Here's why there's is no Flash available for iDevices or other mobile devices. Adobe was unable to provide a product that was suitable to the needs of battery powered mobile devices used for Internet browsing. Existing Flash technology used too much memory, ate battery life, and was buggy. Simply put Flash did not work well on mobile devices.
Apple's Steve Jobs led the escape from Flash dependency when Apple introduced the iPhone, and later introduced the iPad. There was a hue and cry over the omission. Time proved Jobs was right on target.
So this is why there is no Flash for your iPhone or iPad or iPod nor for most SmartPhones. Flash has been abandoned by many sites in favor of supported technologies such as HTML5 or by providing their own custom app.
Here is Steve Jobs official comment on his momentous decision to omit Flash from iDevices: Steve Jobs on Flash.
Here is Adobe's later announcement to cease development of Flash for mobile devices: Adobe on Mobile Flash. Adobe is not providing Flash for Apple iOS devices, and they no longer provide Flash for any other cellular phones. Flash is officially gone.
Now, you are not necessarily out on a limb. There are some apps that can display some Flash, but don't count on there ability to display anything using Flash.
A sample of Apps that can display some Flash content:
1. Puffin
2. SkyFire
3. Photon Flash
4. Browse2Go
5. Swifter
Also, note that many sites that use Flash provide their own app for accessing their material. So check with your favorite sites and find out if "there's an app for that."

MacBook Air used to support 2 external displays

My MacBook Air used to support 2 external (ViewSonic) displays before I upgraded to Mountain Lion. Now it will only support one. It will detect the one using The thunderbolt port but not the one using the USB port.
Can anyone suggest a fix... It is half the computer it used to be.

Well it used to before I upgraded to Mountain Lion. One wend in the thunderbolt/display port and the other one went in either USB. It ran two 24 inch veiwsonic monitors at work and 2 different ones at home without a single hiccup. Now it only 'sees' the one plugged into the thunderbolt port through the display adapter...

Monitor says VIDEO MODE NOT SUPPORTED after changing display settings

HELP! I am about to have a nervous breakdown with my mac mini! I hooked up the mac to my Philips LCD via DVI. No problem at all. But because the screen is only 15" I wanted to play around with the display settings a bit. So I changed the resolution from it's original 1204x768 to the one higher (not sure of numbers) and to my HORROR, I now can't get any picture at all - it says "VIDEO MODE NOT SUPPORTED". I have tried everything I can think of. I have rest the P-RAM, I have unplugged all cables, plugged the back in again, I bought the mac into work and hooked it up to my monitor and changed the resolution back to 1024x768 which is what it was on originally and that STILL didn't work. I can see the Apple logo and then it goes black and comes up with the error message. HELP! What am I doing wrong - I can't believe one click of a mouse button has rendered my display useless!!!

Welcome to Apple Discussions!
Try booting the mini without the display connected, and then, once the system is running, connect the display. This will often force the system to default to a low resolution, and then correctly detect the display when it is connected.
If that doesn't help, with the display connected, boot into safe mode (hold the shift key down when starting up) and once the system is running, change the resolution to 1024x768, and ensure the correct refresh rate is selected. Rebooting normally ought then to give you a good display.
If all else fails, boot into safe mode with the display connected, and then in the Finder's file menu, use the 'find' option to search for 'windowserver' (no quotes). You should get 2 or 3 results, including one with a string of alphanumeric characters. Move all of them to the trash and restart normally.

Native resolution does not fill entire external display

I've got one of the original MacBook Pros with the Mobility Radeon X1600 hooked up to a Samsung P2350G display (it's a 23" LCD panel.) The native resolution on the display is 1920x1080.
The display has inputs for both VGA and DVI. The DVI port however is used by a desktop PC already, so I use a DVI to VGA adapter on the MacBook Pro, and use the laptop panel as a secondary display.
The problem is that when I set the external display to its native resolution, I get vertical letterboxing and some flickering along the edges of the image. It does not horizontally fill the whole display as it should. I have tried the same adapter on the PC and it worked fine (though with rather spotty image quality.)
Resolutions that are lower than 1920x1080 work fine and fill the whole display properly. I'm not exactly sure what the issue is. The laptop is only semipermanently attached to the large display so I can live with a reduced image quality there, but the flickering, slightly distorted image is just not acceptable right now.

Sounds like it might be a sync issue. Have you tried powering the monitor off and then back on with the MBP connected to it? How about just temporarily disconnecting the DVI cable from the desktop PC and using that to plug into the MBP.

MBA not always recognizes external display after sleep

Hi,
I have a 2011 MBA and use it on a external display (Dell 2709w) with the lid open. The issue with this MBA is that after sleep it often (every second time I wake it up) doesn't show anything on my external monitor. In order that the external monitor works again I have to plug the DVI cord out and in or press recognize monitors under monitor settings.
I also did a PMC and SMC reset but both did not help.
I have also done a complete reinstall witch did not help as well.
I also did a test with a MBA from a friend (exact same model) and his always works with the external display after sleep while mine only works every second time.
Could this be a hardware defect? sound pretty strange to me, but who knows...

I have managed to make the Apple Hardware test by just pressing "D" while restarting. The test, however, did not find any error - but this does not surprise me as I think it only tests the ram.

Images in Photoshop and Lightroom not matching on external display

On my external display the same image viewed in Photoshop and Lightroom is diplayed differently.
My set up:
Macbook pro running Mountain Lion (10.8.4), DVI connected NEC Spectraview 271. Photoshop CS4 and Lightroom 5. Both displays calibrated using Spectraview 5 software and an Eye one pro puck. Photoshop working space is Prophoto RGB and is set to preserve embedded profiles. I'm using Andrew Rodney's and Bill Atkinson's test images to try and figure this out.
Behaviour:
With the same image displayed in Lightroom and Photoshop on the Macbook screen they match perfectly. If I drag the Lightroom window across to the NEC it changes (as you would expect - richer colours & higher contrast). If I drag the Photoshop image across to the NEC it also changes but no longer matches the Lightroom image (cooler colours).
So, I don't really know whether Photoshop or Lightroom is displaying correctly, and whether they or the OS are to blame. I had assumed it was Lightroom as the image is more pleasing but this obviously isn't necessarily the case. What is clear is that somewhere there is a difference between how Lightroom and Photoshop are converting the image numbers for monitor display on the NEC.
Does anyone know how to find out what display profile Lightroom and Photoshop are using?
Is it possible they are both using the same profile but one is not using the NEC hardware calibration? (Seems unlikely as I assume it would be impossible for the NEC to be using different internal look up tables at the same time)
Could the OS be tripping up one and not the other in some way?
Could the X-rite software (which I don't use but is installed) somehow be interfering?
Anybody able to shed some light?
Thanks for any help,
Tom

I'm having trouble with Lightroom 5 soft proofing with reds too. To rid my propossed print of a gamut warning I must totally desaturate or change my paper profile to glossy (or both). This is odd because my monitor is calibrated, I'm using the correct paper profiles etc and when I ignore the gamut warning my prints are looking good. This isn't helpful to you but at least your not alone....

ITunes movie purchases will not play on external display - HDCP auth error

Hello,
Well, I'm surprised there hasn't been more of a storm over this one already but I expect there will be.
Just got a new MacBook last week and finally found a mini Display Port -> VGA adapter so i could use my 19" external display. I rented a movie from the iTunes store yesterday and when I tried to play it on my external display, it gave me a warning/error that the display was 'not an authorized HDCP display' and it would not play. Plays fine on the small MacBook screen, just nothing external. To make it even worse, i tried all the movies that I have purchased from the iTunes store with the same result... NONE of them will play on anything but the MacBook's small 13" screen. This is crazy unacceptable.
Has anyone else run into this yet or have any ideas of something I may be overlooking in order to get purchased movies to play on an external display?
Thanks!

Hm, how many Apple users did I see scorning Vista and its content protection madness; agreeing with Peter Gutmann's searing critique of Vista[1].
And here we are now with Apple users who have spent thousands of dollars on Apple hardware (30" Cinema displays are not cheap!), buying films legitimately through Apple's store only to find themselves screwed when they just want to watch the film!!!
The deeper questions we should be asking is if Apple have done anything to enable end-to-end encryption. Vista made significant sacrifices to efficiency and stability to get there, what has Apple done to our OS? We have no technical details on this yet, but wouldn't Apple be improperly implementing HDCP (in spirit if not letter) if it didn't force end-to-end encryption from source to final destination, most of which has to go through your system?

Flash 'not supported on this architecture' error message

Hi there,
I'm having a problem with Flash and InDesign (both CS4), installed as a bundle in one go from Adobe Master Collection discs, When trying to launch InDesign or Flash, I get a message that they are 'not supported on this architecture'.
I'm on a MacPro with 2x3GHz Quad Core and 4GB running 10.5.7.
All the other CS4 Master Collection apps have installed and run fine.
My volume is formated as Mac OS Extended (Journaled). Any ideas?
thanks
Russell

I have submitted a query to the support people so hopefully I will get some more information.
This is very frustrating. I put a post in the indesign forum, but the indesign snobs told me to come to the flash forum, where the flash experts reside and would help me...ha!
