what causes lines through monitor

Take a screen shot & view that in Preview, move the Preview window around, if you see double lines it's a Video card/VRAM problem, if the lines do not move moving the pic around then it's the LCD or cable.

What causes lines in photos?

When I open photos in Elements 9 random lines appear in image. Lines are not in original images in Nikon software so the problem has to be with Elements. I've uninstalled and reinstalled without any change. Any Ideas?

In addition to updaring your diver check your monitor user manual for recommendations for your windows resolution screen settings to match a multiple of the monitor native resolution. This problem does show up with some LCD monitors and the symptom is the lines changing as you zoom.
If your monitor\video driver offers anti-aliasing you might want to try that but it might interfere with similar smoothing settings for editing.

What causes vertical color lines on ipad2 and how do you remove them ?

What causes vertical color lines on an IPad. And how do you remove them ?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
If still present: Take it to an Apple Store for evaluation.

Don't believe it's a factor, but you should update your iOS.
If you have an iPad 1, the max iOS is 5.1.1. For newer iPads, the current iOS is 6.1.3. The Settings>General>Software Update only appears if you have iOS 5.0 or higher currently installed.

If you are currently running an iOS lower than 5.0, connect the iPad to the computer, open iTunes. Then select the iPad under the Devices heading on the left, click on the Summary tab and then click on Check for Update.
Tip - If connected to your computer, you may need to disable your firewall and anitvirus software temporarily. Then download and install the iOS update. Be sure and backup your iPad before the iOS update. After you update an iPad (except iPad 1) to iOS 6.x, the next update can be installed via wifi (i.e., not connected to your computer).
Tip 2 - If you're updating via wifi, place your iPad close to your router to preclude getting a corrupted download.

Are the lines like psychedelic herringbone? If yes, I had that happen once, it was something serious, like the
Logic board. The good news is that it was fixed without any loss of data on the hard drive. Take it in to have Apple look at it ASAP. I took it to TekServe at the time, they are very nice about preserving your data and user library when possible.
Good luck and don't panic.

How can I find out what causes a program to NOT RESPONDING status suddenly?

After a very long period of functioning without serious problems a program suddenly doesn't start anymore, showing this funny rotating ball and a message in the Activity Monitor that this program is not responding. I have searched the log files meticulously, hoping to find some clues what caused the stuck, but no chance of course. Is there a more or less "educated way" to find out, what happened and how to prevent it in the future?
Thanks a lot in advance

Some of your user files (not system files) have incorrect permissions or are locked. This procedure will unlock those files and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
Back up all data before proceeding.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):
sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
Start up in Recovery mode. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
resetp
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

What causes a macbook pro to suddenly become slow?

I have only had my macbook pro for a year. Well recently it suddenly became very slow to the point where every few seconds the spinning beach ball looking thing came up (loading icon)... and it would stay there for a good 15 seconds then go away for like 5 seconds... what causes this?!?!?! and what can fix it??!?!
HELP!!!!! It also has 350gb left of hard drive space and 2gb of ram... whats the issue

First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
Otherwise, take the steps below when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

What causes this? (RGB/8/CMYK) to come up in some images only?

Hello,
In the title bar of an image, it tells you its color mode and bit mode. Sometimes, the monitor profile shows up as well, in this case CMYK, which is always checked in my machine.
But, if that is the case, what causes some RGB images to show that entire line and what causes it to sometimes just read (RGB/8)?
thanks

Hello, Babs!
You activated proof colors (CMD+Y) for the images with two color modes in their tab.

What causes a slow mouse/cursor response on a fast machine?

I have a system that has always displayed poor cursor redraw performance with certain adobe applications. All rendering and other effects are fast, but basic mouse selections and button knobs are extremely unresponsive. I have searched and searched and can not seem to find out what causes the mouse cursor speed issues. Does anyone have any ideas as to why my mouse would slow for such basic Interface interactions? Do I need to change my hardware, settings, displays, BIOS, etc?
Any insight into what the mouse redraw/refresh is called in terms of computing would help me search for a solution. And if you have a solution as to why my mouse cursor acts drunk and sluggish when interacting with the Adobe UI's in premiere and after effects and sometimes Photoshop I would greatly appreciate the help.
Thank You. I attached a screen shot of a very basic selection interaction that is dog slow. The selection box redraws like there is a lag in some process associated with the square box overlay.

Your answer is in this part of your specs:

It takes a long time to draw and redraw the pixels to the screen(s) with such large monitors.
We can mitigate this by making some changes in how our UI is drawn to the screen, and such changes are a rather high priority for use to work on for the near future.

What causes BUFFER GETS and PHYSICAL READS in INSERT operation to be high?

Hi All,
Am performing a huge number of INSERTs to a newly installed Oracle XE 10.2.0.1.0 on Windows. There is no SELECT statement running, but just INSERTs one after the other of 550,000 in count. When I monitor the SESSION I/O from Home > Administration > Database Monitor > Sessions, I see the following stats:
BUFFER GETS = 1,550,560
CONSISTENT GETS = 512,036
PHYSICAL READS = 3,834
BLOCK CHANGES = 1,034,232
The presence of 2 stats confuses. Though the operation is just INSERT in database for this session, why should there be BUFFER GETS of this magnitude and why should there by PHYSICAL READS. Aren't these parameters for read operations? The BLOCK CHANGES value is clear as there are huge writes and the writes change these many blocks. Can any kind soul explain me what causes there parameters to show high value?
The total columns in the display table are as follows (from the link mentioned above)
1. Status
2. SID
3. Database Users
4. Command
5. Time
6. Block Gets
7. Consistent Gets
8. Physical Reads
9. Block Changes
10. Consistent Changes
What does CONSISTENT GETS and CONSISTENT CHANGES mean in a typical INSERT operation? And does someone know which all tables are involved in getting these values?
Thank,
...

Hans, gracias.
The table just have 2 columns, both of which are varchar2 (500). No constraints, no indexes, neither foreign key references are in place. The total size of RAM in system is 1GB, and yes, there are other GUI's going on like Firefox browser, notepad and command terminals.
But, what does these other applications have to do with Oracle BUFFER GETS, PHYSICAL READS etc.? Awaiting your reply.Total RAM is 1GB. If you let XE decide how much RAM is to be allocated to buffers, on startup that needs to be shared with any/all other applications. Let's say that leaves us with, say 400M for the SGA + PGA.
PGA is used for internal stuff, such as sorting, which is also used in determing the layout of secondary facets such as indexes and uniqueness. Total PGA usage varies in size based on the number of connections and required operations.
And then there's the SGA. That needs to cover the space requirement for the data dictionary, any/all stored procedures and SQL statements being run, user security and so on. As well as the buffer blocks which represent the tablespace of the database. Since it is rare that the entire tablespace will fit into memory, stuff needs to be swapped in and out.
So - put too much space pressure on the poor operating system before starting the database, and the SGA may be squeezed. Put that space pressure on the system and you may enbd up with swapping or paging.
This is one of the reasons Oracle professionals will argue for dedicated machines to handle Oracle software.

Mac randomly crashes, screen turns green and white, and it works fine upon restart. What causes this and how can I fix it?

My MacBook Pro 13 inch (I've had it for about a year and a half) has started crashing randomly. It happens about once a week and it will happen when I'm in the middle of either watching a video, typing a paper, playing a game, etc. The computer clicks loudly and the screen becomes a series of green and white lines. It works fine upon restart, but it's still annoying whenever it happens. What causes this? Is it fixable?

The image suggests an issue with the graphics board.
The issue may happen more when your machine is generating additional heat, as when you're watching or processing video, or gaming. I can't say for certain, of course, but certain things will reduce the chance of the problem recurring:
1. Keep your machine as cool as possible. When there's additional heat, turn up the fan, or use an app like HD Fan Control to reduce the heat. Use your computer the way you see fit, but be conscious of heat.
2. Back up on a regular basis. Logic board problems can lead to more serious issues down the line, so backing up is a good way of safeguarding your data.
3. Look up "Logic Board Woes" on Google for a comprehensive discussion of the issue.

What causes blank pages appearing suddenly in an autoflowed-text document?

CS5.5, english version.
The complete book was built-up and all master pages were applied . When reopening the file, several blank pages appeared at two places in the document. The text flow was not interrupted, but seamed «hidden» under a non-existing white layer. The software showed «Master page applied», but the pages were blank, imposible to select any object or to place a new text frame. It was also impossible to reapply the master page (the pages were still blank after). We could not access the hidden part of text, even if it was obviously still present, and we had no choice but rebuild a new document.
We don't know what caused this very disturbing bug, and we would avoid it to reappear again! If someone knows a trick, you're welcome!
Version : Indesign CS 5.5, en anglais.
Le livre était monté en entier avec pages maîtresses appliquées. Lors d'une réouverture du fichier, plusieurs pages vides sont apparues, à deux endroits dans le document. Le texte n'était pas interrompu, mais semblait «caché» sous un calque blanc. Le logiciel affichait l'icône de la page maîtresse appliquée, mais la page demeurait vide. Impossible de sélectionner une boîte de texte ni de parvenir à réappliquer la page maîtresse. Nous n'avons pas réussi à accéder à la portion de texte «cachée» sous ces pages vides, bien qu'elle n'ait de toute évidence pas été perdue.
Nous n'avons pas trouvé d'autre solution que de recommencer le montage à zéro à partir d'un nouveau document, mais nous ne savons pas ce qui a causé ce problème, ni comment éviter qu'il survienne à nouveau.
Si quelqu'un a déjà rencontré cette anomalie et peut m'informer, bienvenue!

I'm afraid I don't have any good news for you, though I was able to get the text to reappear by deleting the blank pages and inserting new ones, then rethreading. Youy could do this, but I suspect it is a short-term fix that won't last a day and more important, that output will fail.
ID seems to think the frames on the blank pages are lines with astronomically long lengths and they seem to be sheared as well. Needless to say that seems to be some sort of corruption in the file. The reason that I don't have good news is that I've been completely unable to export anything useful for repair out of the file and reimport it-- neither .idml or tagged text. In all cases I get an error message that the either the file does not exist, it is in use or I don't have permission. I know the files exist -- I can open the text file in a text editor, and I can see the components of the .idml file if I change the extension to .zip, but I can't convince any version of ID to access either of them.
I looked through the file history and noticed that this file began life as a CS4 file that was converted to CS5.5 in August of 2011. I think that's the source of the problem. From time to time we get reports of unexplainable glitches or files that will not output, or just refuse to open at some point, even though they were fine hours earlier, and quite often it turns out that these are legacy files that were directly updated in a newer version. Because of this I now recommend that all legacy files that are to be converted be exported to .inx or .idml from the original version, then that exported file should be opened in the new version.
Actually I had one more thought, and it seems to have been at least partly successful. As I mentioned, I was able to export the main story to InDesign Tagged Text and open that in a text editor (Notepad in this case, since I'm on PC). I tried saving the file from notepad with a new name and lo and behold I can now import it into a new file or use it to replace the text in the original. I tried the replacement, and exporting another .idml. but that still fails to reopen, so the corruption is not in the text of the main story. A .idml file export from a new .indd with the resaved tagged text placed in it also is working.
This means you actually have a good shot at rebuilding this file fairly quickly. Export the stories to tagged text, open those in a plain text editor of your choice and resave as plain text, then place them into a new document with the same page dimensions and margins (rebuild the master pages from scratch in the new file). Make a backup copy of the file with just the text, and make sure it is working properly and that you can export to .idml and PDF, then add the images and check again. I think this is going to work, though it may take a few hours.
DON'T overwrite any of the files you have already -- use new names, and do a save As a the end of each session or at any major change point adding a version number to the name so you have a good backup version chain in case something goes wrong again. Good luck.

What causes banding in Color Gradients?

Using CS6, I created a sky gradient on a new layer, then imported some photos to other layers for a composite. Then I noticed horizontal banding of varying widths in the sky area of the gradient. When I use the Move Tool to move the gradient layer around, the bands move along in a fixed position, so it's not my monitor. When I Option-click on the gradient layer eyeball icon to make just that layer visible, there is no banding on the screen, just a smooth gradient as it should be.
I have never noticed this happening before. What causes it and what can I do about it? Thanks.

Are you absolutely sure it isn't a display issue? I tried to produce banding after an earlier reply, so as to see just what difference I'd see at different bit depths. I change just one channel by one number from foreground to background, and ran gradients right across my 30 inch Dell Ultrasharp, and couldn't see any problems at any bit depth. I didn't try saving out to JPG and reloading, or reducing the file to Indexed colour to lower bit depth still further, but I was reasonably sure that I would see a problem after doing so.
