Help Scripting "Mirror displays" and resolution

HI there,
I work in a situation where it would be super helpful to have a script that runs at login that sets the resolution to a specific resolution and even more awesome if the script could make them "mirror displays" as well.
Any help would be so GREATLY appreciated!?!?!?!

Mirror Display means just that. It puts what's on the MacBook to the Samsung's screen including the macBook's resolution. In System Preferences>Display there should be an Arrangement tab when you have the MacBook hooked up to the Samsung and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen. You can now use your MacBook in Clamshell Mode with a wired or Bluetoothkeyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.

Applescript mirrors display and resolution

Hi,
I have many problems with Mavericks and external monitor resolution (it's a projector, in 1024x768).
I can't see the 1024x768 resolution for the external monitor (I see only 1280x... and 800x600). I need to hold ALT and click to scaled.
For this problem and others, i search a Applescript for :
active Mirrors Displays (if the checkbox is not already checked)
set resolution 1024x768
My computers are in Mavericks.
It is possible?
Thanks
PS : excuse me for my bad english

Can you share the type? Model, type etc.

Messed up color display and resolution because of mini-DVI to video adapter

Once I connected the mini-DVI to video adapter to the tv and got weird colors on my screen for a while but then it worked out, then after a while I disconnected the cable and turned my computer off. After that, everytime I turned my macbook on, the color is fine for two seconds and then it turns into a weird offset color, really bright colors, kinda sketchy and just a few colors, and a weird resolution and display obviously, but then I just connect my Mini-DVI to video adapter and disconnect it again (quickly) and the color returns to normal. How can I make the normal colors stay and not have to connect the mini-DVI to video adapater everytime I want to see the normal color display and resolution??
please help!

Open the Universal Access pane of System Preferences, click on Seeing, turn off the White on Black, VoiceOver, and Zoom options, and drag the Contrast slider all the way to the left. If the issue persists, create a new folder on the desktop, drag half of the items from the Library/Preferences/ folder of the item in the Finder's sidebar with the house icon into it, and narrow down the files until you've isolated the one responsible.

Help with Conditional Display and Validation

Version 4.1.1.00.23
Hello,
I'm having a difficult time with a conditional display and validation I'm hoping someone can help with.
Requirements:
When the Start Date (Datepicker) and/or End Date (Datepicker) change then display the Change Reason (Select List) and Change Description (Textbox)
If the page is saved without entering a Change Reason display a validation error message that the Change Reason cannot be empty (NULL)
What I've tried
Create a Dynamic Action on the Start Date
Event: Change
Selection Type:Item(s)
Items(s): P51_START_DATE
Condition: none
True Action Section:
Action: Show
Fire on Page Load: Checked
Show all page items on the same line: No
Affected Items Section:
Selection Type:Item(s)
Item(s): P51_CHANGE_REASON,P51_CHANGE_DESC
I've also created a Dynamic Action with similar settings for the P51_END_DATE.
I created a Validation for the P51_CHANGE_REASON as Function Returning Error Text:
DECLARE
    v_start_date    work_items.start_date%TYPE;
    v_end_date      work_items.end_date%TYPE;
BEGIN
    SELECT start_date
          ,end_date
    INTO   v_start_date
          ,v_end_date
    FROM   work_items
    WHERE work_items_id = :P51_WORK_ITEMS_ID;
    IF ( (v_start_date != TO_DATE(:P51_START_DATE,'DD-MON-YYYY') OR v_end_date != TO_DATE(:P51_END_DATE,'DD-MON-YYYY') ) AND
          :P51_CHANGE_REASON IS NULL ) THEN
        RETURN 'Change Reason must have a value';
    END IF;
END;
The Issue
I tried to create another Dynamic Action to hide the P51_CHANGE_REASON and P51_CHANGE_DESC fields on page load, but when either of the date fields are changed and the validation is fired the P51_CHANGE_REASON and P51_CHANGE_DESC are hidden again.
There are two buttons to submit the page: 'SAVE' will submit the page and stay on the page and 'SAVE_CHANGES' will submit the page and branch to the previous page (which is a report with EDIT buttons to edit the record).
I can't get the page load Dynamic Action to NOT fire when the validation is fired.
I hope this is clear and if not what information can I provide?
Thanks,
Joe

Phil,
Thank you for looking at this.
Yes if the Change Reason is NULL when the edit page is displayed then the Change Reason and Change Description fields are hidden. If the Start Date (Datepicker) and/or End Date (Datepicker) change then display the Change Reason (Select List) and Change Description (Textbox). If the page is saved without entering a Change Reason display a validation error message that the Change Reason cannot be empty (NULL).
The problem I'm having is that if no Change Reason is entered and the page is saved thereby firing the validation the Change Reason and Change Description fields are hidden again (because of the On-Load Dynamic Action to hide them). So now the user can't put in a Change Reason...unless they change one of the date fields again which isn't going to be accepted.
Is there a way to determine if a validation error was fired and be able to use that on the On-Load Dynamic Action to hide the two fields? Something like...If the validation fired then don't run?
Please let me know if I'm still confusing you.
Thanks,
Joe

Help with simple display and add in ADF/Struts app

I created a simple ADF/Struts application based on the HR schema. I have a department view object and entity object based on the Departments table. From the Struts page flow designer, I create a data page action (viewDepartments) that binded to a departments view object by dragging the departments view object as a "Read-Only" form from the palette with the navigation buttons --- this page will just display the departments. Next, I created another data page action (addDepartments) that allows a user to add a department. I did this by dragging the departments view object from the palette as an "Input Form" and then dragging the "Create" operation onto the data page action. Each data page action has its own JSP of course.
I'm noticing that every time when I go to to the "addDepartments.do" and then go to "viewDepartments.do", a blank record is added to the view object. Why is this? Also, I want the Submit button to do the "save and commit" in one step. How do I do that?
If it helps, I can email anybody the workspace file so that you can see this behavior.
Thanks.

Need help:Scripting on windows and Sql Loader

I need some help regarding script work on windows machines i.e., how to write a script,the file extension,how to run the script etc,how to schedule it...
I also need the doc regarding sql loader(complete details.....)
Thanks in advance...

The sqlldr utility is fully documented in the Oracle version# Utilities manual for your version of Oracle. You can find the documentation sets here on OTN for download or you can use the online versions at http://tahiti.oracle.com
There is a product called Script Works and it is documented by the vendor. Otherwise the details depend on the scripting language/tool you use: DOS, Perl, etc....

Help with aspect ratio and resolution nightmare

I am currently working on a documentary and all the footage I was given are in different formats an resolutions. Some are in 720 x 480 others in much larger aspect ratios. Some are standard SD some are HD
is there any way to conform all of these together, or any tips? what about exporting? any help would be appreciated.
thanks

What's your final delivery format?
What I do, and I usually have some HDV to mix with DV is to put everything on a ProRes 422 sequence with the setting to the highest resolution I have to start with (usually HDV 1440x1080) but I don't let FCP automatically change the time line or covert anything until I do a render. Then I finally do a render all and FCP up rezzes stuff when it renders. I use very little of the DV stuff (it's a backup when I need something that the HDV cams didn't video the way I need, such as both HDV cams moving to a point of view at the same time).
If you don't need to intercut the various pieces (that is, if you can edit each one as an individual piece in its owns sequence, then just stitch them together end to end at the end), then I create each one in its own sequence, and let FCP change the sequence settings when I drop the video into it. Then I stitch it together when I get ready to make the DVD.
My DVD's are all SD, so I use compressor to downrez and compress: then they are all in the same resolution, etc. and I stitch it together in DVD SP as stories, or just drop them into the same video line, end to end.

Help! What size and resolution?

Hi everyone,
I have been asked to complete a digital painting of a standing girl that can be both printed at around life size (so around 1.5 metres/~60 inches/1500mm tall) and also used on a website.
I have never done something to this size before and I am just seeking some advice on how to set up my document in Photoshop. I am guessing the settings should be set for print.
I realise the file is probably going to be huge... gosh, is this even possible?!
Thank you in advance, I reall appreciate your help!

The first thing you need to concider before starting the art work, i will also agree with the fore writer who said that you're to design it at one third of the size.
Your DPI should be not less than 150 and not more than 300dpi,mind you not to put the sizes while on pixel but put "mm" for the above sizes i have given you.
With large digital printing you will need to have a managable sizes not more than 2gig. If you design the same image with AI it will come out with the best and even the size when saving, save it as a PDF file not in layers .
I wish you all the best in your work.

Multiple Problems after Leopard upgrade HELP! Video display and FW problem

I don't know if this is related.. but I've been battling multiple problems ever since I upgraded my G5 to Leopard a week ago. Everything was perfect under Tiger.
Well, I think I've got everything solved except two last things.
1. My 750GH Maxtor Firewire drive... when I plug it in... does not show in the desktop and it causes both my internal drive and two other Firewire enclosures to disappear from the desktop. I can see all of them mounted in the disk utility, but if this one drive is plugged in.. all icons disappear from the desktop. If I unplug or unmount the 750GB drive.. everything comes back.
I've reformatted this drive, etc. This does not happen on my MacBookPro. The drive mounts fine on that. I've tried different cables, I've tried USB (it's a triple interface Maxtor) and nothing seems to work. I would assume there's something wrong with the drive and not my desktop... but the drive works fine on the MacBookPro.
PLEASE!! Any clues would help...
The other problem that only occurred directly after upgrading to Leopard... is that my graphics now get corrupted and garbled. I've got two video cards running two LCD monitors. The card giving me problems is the ATI Radeon 9800 Pro (256MB). What happens is.. first all the window shadows and top menu bar start getting checkerboard patterns.. then the whole screen starts getting variants of different colors and checkerboard patterns. After awhile and refreshing the screen a few times... the problem goes away for a bit. Then comes back.
Again, this card and my entire system and drives were working fine under Tiger. Now, I don't know if I have a bad card? Is there something wrong with Leopard on my G5 2Ghz DP? Did my Maxtor 750GB triple interface drive just go bad with the upgrade?
I don't know where else to look, I'm guessing the "geniuses" at the Apple store won't help me since this machine is out of warranty. Any help would be HUGELY appreciated. I've been battling all these problems ever since I started the Leopard upgrade 4 days ago and have not got much sleep.

The drives not or disappearing on the desktop could point to the need to do a pram reset.
I believe you hold down the apple-option-p-r keys at startup and listen for a couple of chimes.

Prevent Retina iMac defaulting to 'mirror displays'

Hello! I have a Retina iMac (Yosemite) connected by Thunderbolt>HDMI adapter and HDMI cable to a Samsung 32" TV. How can I stop the iMac defaulting on start-up to 'mirror displays' (forcing it to a low resolution) despite deselecting 'mirroring' in display preferences? I will never use mirror displays and only ever need an extended desktop. Many thanks in advance

I just thought I'd answer my own question here, in case it is of any help to anyone!
I realised my iMac is just within the three-month Apple Care telephone support period, so I rang them up, and they were terribly helpful. We went through a number of elimination processes, and eventually the "don't mirror displays" preference was finally remembered by deleting the com.apple.systempreferences.plist file.
However, this was not actually the cure - one of the the processes we did to eliminate certain things was to set up a test account in addition to my own account. After doing this, naturally we had to disable auto login.
So after the euphoria of fixing the problem by deleting the .plist file, I hung up and deleted the test account and re-enabled auto login. And the problem returned!
So the problem actually lies within enabling Auto Login....so for the time being, I will leave it disabled. If anyone has an answer as to why this may be, I'd be ever so grateful to hear from you, as my dream scenario would be to re-enable it!

Mirrored Display. How to sleep MBP display without closing LID to keep the machine vented?

I just got my hands on a 15" MBP and I currently have a third party Display that I have connected to my Display output port. Mirrored display, and tried the clamshell mode but machine got quite hot by running in it that way. I was wondering if there is any way to keep the lid open while the mirrored mode on the external Display still runs?
Also, if there are any third party software that does give me flexibility as to which display to sleep and such, and at least have control over the display output options, that would be a gem. Appreciate it if anyone has that info?
Thanks a lot for taking time to help! Happy holiday and a great year to come for all!
Miles of smiles,
Jimbo

Captfred,
I've tried what the article suggests but it only seems to work if you want to wake the computer when it is sleeping or the screen saver is on.
What I am trying to find out is how to start the computer when it is turned off without having to open it. I would imagine that there would be some key combination on the keyboard or perhaps a way to program the on/off button on the side of the Apple external display to do that.
Any ideas ?
Thanks in advance.

Mirror Displays not working

After recently purchasing a new LCD television, I noticed the composite video out from my MacBook was not ideal - there were two sets of wavy horizontal lines.
I then bought a mini DVI to VGA adapter to use with the television's VGA input, which produced a much higher quality output, free of the horizontal lines.
The problem I have encountered is that I can only mirror the displays, not use different resolutions as I could with video out. I noticed some strange irregularities when changing resolutions. When attempting to uncheck "Mirror Displays" and perform some other tasks in the "LCDTV" window, there is a beep and then nothing happens. The "Mirror Displays" checkbox remains unchecked but no action is taken.
I am using Leopard, version 10.5.1. Is it possible that the problem is attributed to the LCD television? Is there any way to diagnose what the problem is?
Thanks.

I assume you specified the screen in vlc's video preferences and that screen is enabled when you play the video. I'm guessing it's probably a bug (yet another bug) in vlc 2.x which I also assume you are using. I long since gave up on vlc 2.x and stuck with vlc 1.1.12 which never has problems selecting my desired screen for full screen display (my TV).
I suggest you look at and possibly post this problem to the vlc mac forum.

Display mirroring and resolution

Hi,
I'm trying to set up my macbook for presentations using an apple vga adaptor. When I plug into an external monitor, everything behaves as I expect until I switch ON mirroring. When I do this the macbook screen becomes square (even though the resolution is set to 1280 x 800), with large black edges.
Any thoughts?

Hi stu19,
taken from the Video Developer Note found here: http://developer.apple.com/documentation/Hardware/Conceptual/HWTechVideo/Articles/Video_implementation.html#//apple_ref/doc/uid/TP40003994-SW741200331181
*External Display Modes*
The computer supports two external display modes: video mirroring and extended desktop. The default is extended desktop mode. To toggle between the two modes, use the Displays pane in System Preferences.
*Extended Desktop Mode*
In extended desktop mode, the resolution of the two displays can be set independently. In this mode, the maximum external display resolution supported by the MacBook is 2048 x 1536 at 60 Hz for analog displays and 1920 x 1200 at 60 Hz for digital displays.
*Video Mirroring Mode*
In mirroring mode, a single resolution is used for both displays. The highest resolution possible is the native resolution of the internal display (1280 x 800). If the external display can support a higher resolution than the internal display, that higher resolution is unused in mirroring mode.
*If the external display cannot support the full resolution of the internal display, the lower resolution is used for both displays.* A suitable resolution for both displays should be chosen in the Displays pane of System Preferences.
*Scaling and Black Borders*
In either extended desktop or video mirroring mode, choosing a lower resolution than a display supports results in scaling up the image, if possible. Depending on the supported resolutions, aspect ratios, and refresh rates of the two displays, the scaled image may not fill the screen of one display, in which case the image on that display has black borders. This black border typically occurs when the resolution chosen has a different aspect ratio than the display. It does not occur on CRT displays.
Hope it helps
Stefan

Help please. Extended display won't work on MBP and AOC 20" 1600 x 900 60HZ monitor. Mirror display does. I've a mini dvd to vga converter cable. Should this work?

Help please. Extended display won't work on MBP and AOC 20" 1600 x 900 60HZ monitor. Mirror display does. I've a mini dvd to vga converter cable. Should this work?

I have the same mini display port adapter and Belkin DVI-HDMI cable (but a Panasonic 42" Plasma HDTV) so just set this up on it to see if I could duplicate your problem, unfortunately for you (but good for me) I can't.
I connected the adapter+HDMI cable before switching the HDTV on and then powered up the MBP. It (the HDTV) came up with my background right away (it's set at Mirror not extended Desktop) and when I run System Preferences/Displays get the following. Sorry but all I can confirm is that adapter+cable combination should work ...
Try doing a Parameter RAM reset - hold down command/option/p/r keys at start up and wait for three chimes before releasing the keys?
