Scrolling horizontal line of distortion when in hardware mirror mode

This distorted line that appears while using Dashboard or Expose only happens when my dual screens are in mirror mode. I've tried all the obvious but have now lost countless hours trying to figure out this problem: replaced video card, replaced Mini DisplayPort to Dual Link DVI adapter, reset PRAM and started a fresh account on an external drive. Nothing fixes it. Here's a video: http://www.youtube.com/watch?v=xoaRfRuqFa4

Yeah, I usually go with Crucial RAM, but I wanted to see if Apple RAM was any different (it's not). I also would like to mention that my Apple Care guy is back on board trying to help me with this. He told me that there is a known issue that appears while running dual 30" Cinema Displays in mirror mode (I would have never bought this setup had I known). I guess that's why they stopped making them. Now I'm trying to get info on this graphics card to see if it's a possible fix (http://store.apple.com/us/product/TW386LL/A?n=graphic_cards&fnode=MTY1NDA5OQ&mco =MTA4MzU2Nzg&s=topSellers). I have two concerns though. Concern #1: will this card degrade computer performance speed? Concern # 2: on a review of the card, someone said that anything other than the stock cards will not allow booting from the install disk. Wow, this is turning into a royal mess. Thanks for chiming in though. What's wrong with the 2010 Macs?

My iPad 4 does not show up on my TV screen when in AirPlay mirroring mode using WiFi. The iPad displays AirPlay set to TV with the Mirroring On (green).
My iPad IOS software is 8.2 and my Apple TV software is at 7.1. The TV displays the Apple Menu. The “Settings” does however displays the General menu allowing me to see:
Apple software: 7.1 (7003)
Apple TV: Model No. A1464, Part No. MD199B/A
Signal Strength shows 5 circles.
It does not display the iPad screen but when I use the BT Sport App I can hear the sound but there is no video. I have searched the internet for a solution to no avail. The problem first arose when the IOS was at 8.1+ but it worked correctly briefly when I updated to IOS 8.2. Can you help please?

Welcome to the Apple Community.
Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Check AirPlay is turned on on the Apple TV (turn it off and on if it already is)
Check that both devices are on the same network (Settings > Wifi, on the mobile device and Settings > General > Network, on the Apple TV).
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Restart your router. (Also try removing it’s power cord for at least 30 seconds)
Restart your mobile device.

I have a 4500 G510n that leaves horizontal lines in photos when printing

When printing photos I get horizontal lines about 1/8 inch apart from the top to bottom. I have tried to set the print quality to a better resolution and it doesn't make any difference.

I understand you're getting horizontal lines when you print photos. I would take a look at this document.
Let me know how it goes.

My macbook pro decided to give a different res and a horizontal line follows my cursor (like a diagnostic mode or something) i have shutdown/restrted. Fixed the res but the cursor problem still exists any help please.

I was using my mac as normal and then my resultion on mr screen changed which i have fixed using the normal methods but i still continue on getting a horizontal line whereever my cursor is even after i have restarted and shut down. The line is a white colour but my other screens seem dulled wherever this line is not following it is not a solid white. It looks like its in a diagnostic mode or somthing. Any help would be appriciated, thanks.

It is possible there is a problem with the computer's graphics, but try a simple fix. viz. reset the NVRAM / PRAM.
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Audio from headphones gets distorted when switched to "entertainment mode" w

the sound quality from my headphones gets messed up whenever I switch to "entertainment mode." when i say "messed up," i mean the volume would constantly fluctuate from really high to just noise then high again.
however, when i switch it to "game mode" all the problems disappear.
why are my headphones (sennheiser pc50) not compatible with "entertainment mode?"
i have a creative x-fi xtrememusic card.

I had a similar problem using X-Fi Fatalty. By similar I mean everything worked until switching to entertainment mode. When in entertainment mode all audio had a horrible amount of loud static and noise riding on it. This wasn't limited to headphones though as the same occurred using my 2. speaker system. I was using the latest driver, from June of '06 I believe.
I rolled back to the driver on my install CD (version 5.2.2.43 dated 8/8/2005)and it solved the issue.

Horizontal Lines Scroll Down Screen during Video Playback

I just bought a brand new 20" iMac G5 iSight a week ago and there are horizontal lines scrolling down my screen at random when I play any movie trailers or DVD movies. Anything related to video it seems!
Also, today I bought a VGA-VGA adapter to connect my iMac to my DELL 2005fpw in my first MIRROR TEST and am playing TOP GUN right now on both monitors. It's pretty awesome! HOWEVER.......
Lines scroll down the screen on my iMac display but there are NO LINES that appear or scroll down on my DELL while watching movies/trailers!! I searched the threads but don't see anything closely related to this. Just other threads about white, yellow, and green lines. There is the topic just below this one but I thought I better add another to be sure.
I love this iMac! ANY SUGGESTIONS? Or fixes?
I guess I better take it back Monday and get it replaced! Hopefully, my Apple Store will replace it and NOT try to repair it..

Well sooo far.....
It appears the VGA to VGA video adapter is the culprit! I was about ready to reinstall the original 10.4.2 disk to get my old video driver back.
Instead, all I had to do was turn off my Dell Monitor and the "scrolling horizontal line" on my iMac when playing DVD's/movie trailers ~~ seems to have gone away. I turned my Dell back on and played both DVD's and trailers and the line reappeared on my iMac with none showing up at all on my Dell.
I'm a little confused as to why this is happening! Not sure if the adapter might be bad or if the iMac is just having issues "sharing" the signal?????
However, my new iMac seems to be flawless except when trying to use "monitor mirroring.
STILL.......ANY IDEAS OR SUGGESTIONS WOULD BE WELCOME JUST IN CASE!!!
Thanks

Line drawings distorted by Adobe Reader's Thin Line Enhancement feature

I am working with InDesign CS6 on an engineering textbook with approximately 1300 line drawings. When a pdf exported from InDesign is viewed in Adobe Reader XI, the line widths of the drawings are distorted by Reader's Thin Line Enhancement feature. The default setting for Thin Line Enhancement in Reader is on. I understand that Reader's user features cannot be controlled by a document. Is there anything I can do in InDesign to would reduce the effect of Reader's Thin Line Enhancement on the image quality?
(Ironically, the art work drawn in Illustrator in a pdf and exported from InDesign looks fine in Google Chrome, but wretched in Adobe Reader!)

Thank you for your response. The textbook is to be printed and presented as an ebook. The print version is not a problem nor is the ebook version when viewed in a pdf viewer other than Adobe Reader, or in Adobe Reader in the non-default state with the Thin Line Enhancement feature disabled.
I attempted to resolve the Adobe Reader Thin Line Enhancement problem by increasing line widths and ensuring that interrupted lines segments were aligned. Sadly, the overall size of the illustrations limits the the maximum width of the thinnest lines and Thin Line Enhancement problem persisted.
The reason I ask if there is anything which can be done within InDesign to counter the distortion of Reader's Thin Line Enhancement is the following observation. An MS Word document with the same illustrations embedded as png graphics and saved as a pdf does not suffer the Thin Line Enhancement distortion when viewed in Adobe Reader. I am hoping that whatever is done when MS Word saves a document as a pdf can be replicated when InDesign exports a pdf. Unfortunately, I am constrained by my publisher to link rather than embed the graphics. I have experimented linking eps, Illustrator, and pdf graphics files but they pdfs exported from InDesign were distorted when viewed in the default configuration of Adobe Reader.
I must disagree with your assertion that the only correct way to view the pdf is in Adobe Reader. Adobe Reader distorts the images unless the user has disabled the Thin Line Enhancement. I believe that I am a typical user of Adobe Reader in that I was unaware that the feature existed until recently. I mistakenly presumed that what may have been distorted graphics were simply poor quality graphics. Given my choice, I would hope that none of the future readers of the text use Adobe Reader, but, unfortunately, I know that many will. That is why I am attempting to resolve this problem.

Drawing a horizontal line

I have a LineChart, with a few series on it, and I want to
draw horizontal lines to indicate when the series fell above or
below various critical values. I can't find a way to do this other
than to make each line a series of two points, but this seems like
sort of a hacked way to do this. Is there a more direct way?

Final Cut Pro Problem: Green Horizontal Lines

Ok first of all i am using Final Cut Pro 7 and i have an iMAC with 2.66 Ghz Intel Core i5 processor and 4 GB Memory although i store my Final Cut Pro files on my 1 TB external hard drive.
These green horizontal lines show up when i add and render a transition inbetween two clips. It happens consistently everytime i add a transition.
It really looks bad and if someone could tell me how to fix this it would be great. Thanks!!!!

details of source clip formats, sequence settings etc? specific transition settings? screen shots displaying issue?

Display the horizontal lines whether or not a section is empty.

I am using CR with vb.net 2010 and latest version of CR for net 2010. I want to print a report like a grid which means horizontal and vertical lines appearing whether or not there is text in a section.
I have a box surrounding the report and vertical lines extending down the report. There are two group headers and a details section.    The horizontal lines only appear when there are values in the group or details sections. Thus, once the detail lines end (and therefore there are no more groups either) on a page, the horizontal lines stop though the vertical ones continue. I want the horizontal lines in the sections to continue as well -- just like in Excel.
There is a page break for the top group so there are lots of pages that have detail lines empty. How do I print horizontal lines in those sections as well when there are no values.

hi Suzanne,
there are several different ways of doing this.
1) the easiest way of doing this is to create a new Page Header that contains all of the lines. this works if you've got a report that is static in way that each page is laid out. make the new page header the size of a page in length, move it up so that it is Page Header A, and go to the section expert and set it to Underlay Following Sections. now add the grid lines to this new page header A.
2) another way of doing this is to create a whole bunch of Details sections....e.g B to Z. put lines in these sections. write a conditional suppression formula for each one based on how many records there are in a group. this is way more work.
3) another fairly easy way is to create a formula that outputs the horizontal lines...i.e.
     numbervar N:= 10;
     // you'd need to figure out what N is based on the number of existing records and the number of lines you want
     replicatestring(replicatestring("_",300) + chr(10), N)
make sure that you right click on the formula and go to Format Field > Common tab, and set it to Can Grow.

Using a new monitor, Mozilla Firefox now has a distracting horizontal line every few lines when scrolling. This doesn't happen with another browser. HELP!

The horizontal, wavering "line" is disruptive when scrolling. What's causing this. Doesn't happen with other browser and I'd like to stay with Mozilla Firefox, if we can resolve this. Thank you.

hi Liza5, maybe that's an issue with hardware acceleration - please try [[Upgrade your graphics drivers to use hardware acceleration and WebGL|updating your graphics driver]] or in case there is no new version available at the moment or this doesn't solve the issue, disable hardware acceleration in the firefox ''menu ≡ > options > advanced > general'' (that setting will take a restart of the browser to take effect).

When scrolling vertically there is an horizontal line which causes distorsion of the screen. I do not have noticed such concern on my iMac or on my macbook. What happen with the macpro ?

I have the new ipad and when I stretch the screen a horizontal line appears when I scroll whatever page or location I am on. The line is not there if the screen is minimised. Any solutions?

I can't personally as I never really liked nor used the picture frame feature in iPad. Just search in the App Store and read customer reviews and you'll likely find something you'll like.

Why is my MacBook Pro **crashing** changing to a blue screen with lines or distorted screen when I open logic or Ableton Live

Why is my MacBook Pro **crashing** changing to a blue screen with lines or distorted screen when I open logic or Ableton Live. Then I have to restart by long pressing the power button. Can somebody plz help me

What you describe sounds like a hardware issue. Unfortunately, you'll need to get that checked out by Apple. If you have an Apple Store near you, make an appointment with the Genius Bar and take the machine in for evaluation.
