Video Artifacts/Vertical Banding issues

I have included a link to an example of some extreme artifacts/banding that is occuring on my new Radeon 9800 Pro Mac Edition (256MB version).
http://www.htadgroup.com/crazyscreen.htm
This card is brand new...was installed for the first time this evening on a Dual 1 GHz G4 / 1.5 GB RAM / OS X 10.4.3.
I have downloaded and installed the latest ATI control panel and ROM flash update and both updates went smoothly...no help with the issue. Reinstalled the 10.4.3 update thinking it may be an issue there...still no luck. The issue has occured from the first moment the computer was turned on with the new Radeon card in the AGP slot.
Anyone have any ideas as to what may be going on?

Hi Rustus !
Nice desktop pattern in the picture......
Do you have the same results at ALL given resolutions, or just at that resolution..?

30" vertical banding issue (thick grey overlay)

I have a 2 year old 30" display which has recently begun having some issues. The problem has only happened twice so far, once 1-2 months ago, and the again a couple days ago. What happens is randomly the screen will get light/dark vertical bands of various thicknesses and intensities. It will stay like this regardless of restarts, leaving the computer and display off for 6+ hours, unplugging and replugging all cords, changing resolutions, plugging the display into other computers/laptops, etc.... for about two days. Then it will "fix" itself.
See pictures here:

I have AppleCare and called support about this issue just now. They won't give me a repair ticket or replacement unless it happens again, in which case I'm supposed to call again, and they'll let me ship it in for repairs. My frustration is that it's happened twice, I'm sure it'll happen again, however if I can get it taken care of now, while I"m between photography projects, then it's a minimal impact, however, if I wait, and it does this again while I'm under a deadline working on a photo shoot, then I'm screwed. I explained this to the support rep to no avail.
I'm going to try bringing it to my local genius bar tomorrow and show them the pictures, since now the display looks normal, and see if they can help me any.
I guess i have two questions:
1) has anyone seen this before? I see many posts about thin colored vertical lines, but I haven't seen this issue before.
2) any suggestions on how I can handle getting a repair or replacement taken care of?
Thanks!

30" Problems Inverted video and vertical banding

I've had the 30" since May and have been having intermittent problems that occur once every few weeks. The problems only seem to occur following sleep (the computer's not mine . The problem for the first few times was that the display was inverted (dark to bright and visa versa) and colors were totally washed out. Examples of these problems may be found:

http://greg.sytes.net:5080/WhiteInverseCrop.jpg
http://greg.sytes.net:5080/WhiteInverseCNN.jpg
For the first time, this morning a new problem occured following display sleep. This time the display wasn't inverted but there were vertical bands of dark stripes with various colors. Here's a snap:
http://greg.sytes.net:5080/VerticalColorStripes.jpg
Spent 30 minutes explaining the problems to an Apple Care rep who did nothing but pass me off to another rep. The second representative took another 30 minutes and opened a trouble ticket but said I had to make an appointment to see a genius at the local Apple store. It's hard to believe that an appointment cannot be made for the weekend. I spent over $200 on the Apple Care agreement and I'm going to have to take time off from work to get this problem fixed! Sorry for the venting.
Has anyone else heard of problems like those described above?
Any isnights would be greatly appreciated!
Best Regards,
Greg

Hi Lin-Chow,
I'm glad I'm not the only one with this type of problem. Have you explored getting Apple to take a look at the bad unit? It's a problem that can be lived with but I'm afraid it could become less tolerable if the frequency or time to return to normal increase.
I still haven't made the appointment with a genius. I guess I just supect that the unit would be shipped back to apple and they would find all is well (unless they keep it for a month).
Regards,
Greg

Macbook display issue - vertical band

The LCD display on my daughter's Macbook got fried because she dumped a drink on it - yes, it was alcoholic. She had some else's fried MacBook laying around so I harvested the LCD display from it and put it in her Macbook. The swap went just fine.
I booted her machine and found a vertical stripe on the right 1" of the display.
You can see the stripe in the photos here:
http://gallery.me.com/carlfino#100011
I checked the connection from the video cable to the lcd display and all was well. I know it's not the connection from the motherboard to the video cable because this stripe did not exist on the previous display and I didn't affect this connection when I swapped the lcd display.
I have no history on the display that I placed in the unit, so I guess it's possible that this stripe was a problem embedded in that display. But, if any of you have suggestions on what could cause this I'd like to hear them.
Regards,
Carl...

I have not tried an external display. The only time it is not there is on bootup, when the grey screen shows. As soon as any colored desktop image shows up the band is there. I also removed the video display cable from the back of the display while the machine was running. As soon as I removed the video cable, the screen went grey, and the band was not there. When I plugged the video cable back in, the stripe returned. Clearly, it's a video problem - the question is whether the problem is rooted in the motherboard or on the lcd display side. I suspect the lcd display, because even though the previous display had liquid damage, I could see the entire display and the vertical band was not present.

Vertical banding lines on iPhone4 still capture

I found that there are vertical banding lines on captured images. on another iphone4 there are no such kind of vertical banding lines.
Is there anybody who has the same issue?

i dont have vertical lines but there's a darker spot when i tried to take pics on light coloured background. and the spot gets bigger and switches to another place when i tried to take video. it's definitely the camera coz i dont see the spot when i looked at the pictures i imported into the phone.
does that happen to anyone else?

Banding issue with brand new MG7550 in Win 8.1

Hi there,
I'm running some test prints on a new Pixma MG7550, but I'm getting a consistent vertical banding on landscape photo prints (i.e. horizontal bands on portrait prints). It's really noticable on gradients, but is there regardless of colour. It looks like a slightly darker line every 8mm or so.
Here are the details:
Pixma MG7550 (Firmware 2.020)
Windows 8.1 Pro 64 bit (Auto update enabled and up to date)
Printer installed on network via ethernet (no other connection)
Canon inkjet printer driver 2.80
Stock (included) cartridges installed
Printing from Windows photo viewer
A4 HP glossy photo paper (landscape mode)
For what it's worth, I was very careful in the setup process and followed all the instructions to the letter.
The print tests look fine, no missing content or obvious errors. The printed image looks just like the reference one.
I've run nozzle checks, head alignments and the clean utility.
I haven't run a deep clean as I understand that this is only necessary when you are sure it is a cleaning problem and I really don't know.
I've updated the printer firmware, but the problem is exactly the same, before and after.
I suspect it may be a Windows 8.1 issue, but only because the Canon site refers to a similar-sounding problem in Windows Vista (where it suggests upgrading to Service Pack 2).
If anyone can offer any ideas, I would really appreciate it.
Thanks!
Solved!
Go to Solution.

Glad it worked out.
I have a Pixma Pro-100 with XPS driver, so my experience is based on that, but I believe they all work the same. As far as the XPS driver is concerned, when you install the XPS driver the computer sees two printers - an MG7550 and an MG7550XPS. If you don't make the XPS printer your default printer in Windows, or specifically choose the XPS printer from the Print menu of your application, then the XPS driver isn't being used.
There is also a lot of Internet discussion over whether or not Windows has a 16-bit printing process.
I have experimented with both. 1. I have not seen a photo printing quality difference visually with XPS over non-XPS. 2. Using the XPS driver hasn't created any negatives that I have seen. So, I use the XPS version just in case there are some subtle benefits I don't see.
But, if you want XPS then you need to be sure to select it.
The print head sticking option moves the head further from the paper; usually selected for heavier weight paper. I don't know anything about the HP paper you are using, and don't know if there a re negatives with selecting it for lighter weight paper, but since you made two changes I would suggest you uncheck that option and print from PS just to see if there is a difference.

Video Artifacts: Radeon 9800 Pro + ACD 23 (Clear) + G5

Hi guys.
I've been experiencing some video artifacts with my retail version Radeon 9800 Pro 256MB (not the OEM "XT" version from Apple) which is driving my ACD 23" (Clear Enclosure), which is connected to a Dualie 2.5GHz G5 running Tiger 10.4.2.
Prior to installing the upgraded video card, I never had this problem, so I am pretty sure it's the card.
It has only happened to me when the G5 wakes from sleep. And it doesn't happen very often, either. Maybe 1 out of 20 wakes from sleep. The only way to get it back to normal is to turn off the G5 completely, disconnect the ADC connector cable from the back of the video card, and then reconnect it and reboot.
I also have a second display connected to a Radeon 7000 via VGA and when the artificats appear, the other display is just fine. The weird thing is that I can actually take a screen shot of the artifacts, which I thought wouldn't show up. I am not sure what that means, but I think the fact that I can take a screenshot of it tells me the display is being corrupted at the system level. Right?
Any help would be appreciated. TIA.
Here's a screenshot:

Hi Bryanus,
Did you have an ADC port on your old card? Do you still have your old card? If this is the case, you can verify that the new card is implicated by re-installing your old card and seeing whether the problem repeats itself.
If you only have DVI on your old card, you would have to borrow an adaptor, but then you are relying on the adaptor to function properly.
If the problem doesn't repeat itself with your old card being used, then the new card is the culprit, in which case I'd ask to have it replaced, or get a refund.
If the problem does repeat itself with the old card, then you might want to consider other possible contributing factors such as the physical state of the monitor connection (dirty or tarnished contacts, bent pins etc.).
If the problem repeats itself with a new (replacement) card, you could add AGP slot issues to the above paragraph.
"Sleep" in an Apple Mac often generates issues with third party hardware, so your primary consideration that it is probably the card is (to me anyway) still the most likely.
All the best with the diagnosis!
Cheers!

Wide black vertical band in display.

My computer (MA590LL-late 2006) has just started displaying a 2.5" wide sold black vertical band just left of center. Otherwise it seems to be working just fine. I want to find out if this is an expensive repair before I take it to Apple because, given it's age, it may not be worth fixing. I found one similar problem within these "Discussions" pages but there was no answer. Can anyone help?

If your waranty's up in 6 days, I'd ship that thing off first thing tomorrow by whatever method it takes. On the old Titanium PowerBooks (and actually on some of the Aluminums) that line meant a pinched display cable or something in the display itself failing. Whatever it is, it's not going to just go away, in fact it will probably just get worse until you have to pay to either replace the display (very expensive) or get it rewired (rather expensive.) I'm certainly no Apple tech, but a line problem like that is usually a display issue needing attention before it becomes worse. Even though you'll be without your computer for a while and it sounds like it'll be a pain to ship it and get it back, I'd still give it a try.

Banding Issues with GeForce 8800

Hi,
I just installed CS4 Production Premium on a new Mac Pro. The system specs are:
2x 3 GHz Quad-Core Intel Xeon
10GB RAM
NVIDIA GeForce 8800 GT 512MB
2x 1TB SAS drives
Samsung 30" Syncmaster 305T Plus
OSX 10.5.6 (both OSX and CS4 are up to date)
When I was working in After Effects, I noticed some dramatic banding issues when lighting a scene. I was curious, so I created a gradient and the same banding was visible. I tried creating a gradient in PS, AI and Flash: same results. Consistent across all CS4 products, and the image depth (8bit, 16bit or 32bit) doesn't affect it at all. Applying a blur effect to any image also produces banding.
I tried finding some gradients through Google image search. They look fine in Firefox, but when I open them in Photoshop the banding once again pops up. Same in Preview to some extent, but not as drastic.
Two other guys in my office are running CS4 with the same monitor. We're running identically calibrated color profiles, and working in the same color space. They have no problems. The only difference between their setup and mine is that they're using Macbook Pros.
Things I have tried: turning OpenGL on/off and toggling the individual GPU settings, working in all available color spaces, working with variable DPI, using another monitor, changing the synchronized color space through Bridge, changing the conversion options (dither, engine, etc), changing the color management policies, working in CMYK/RGB/Gray/Lab, changing the pixel aspect ratio, altering the scratch disks and memory allocation, dumping my CS4 preferences and starting over... none of this affects the banding. A 16bit 72DPI image that's a straight black to white gradient consists of nothing more than 12 or so very visible steps. I'm starting to wonder if this is a graphics card issue.
All the work I'm doing is for screen, so printers don't factor into the equation. I'd appreciate any tips or suggestions anyone can offer.

Well, one thing I notice is that attempting to open the linked .png in Photoshop, it has an embedded "SyncMaster" profile.
Opening it in Photoshop CS4, maintaining that profile, I see banding (although very subtle in the second (bottom) example). The top example exhibits a stippled effect at the band edges at 100% scale.
Opening it and converting it to Adobe RGB 1998, I see almost no sign of banding in that bottom example.
Opening it as is in Preview, I see the banding again.
Creating a new radial gradient in Photoshop CS4, 1300 pixels wide, #666666 to #000000, at 100% scale, it is a smooth transition with the barest hint of banding. Also, my #666666 is noticeably lighter than in your example.
Offhand, I'm not sure which factors affect your workflow. But I doubt it is your video card unless it is set for, say 16 bit or 8 bit...

T410s vertical band in my LCD

I have had my t410s for a couple of months, yesterday a vertical band appeared in my display. A quick search online brought up this: http://www.youtube.com/watch?v=rM9_ZM_8qkQ
which is exactly what I see.
I am about to lose my t410s for a couple of weeks (or so I am told by the Lenovo support rep), is this a problem that Lenovo is able to reliably fix? (namely it is clearly endemic to the t410s as I have seen many posts on the matter, my concern is that their fix is just temporary until it happens again)
Do others who see this problem find that the repair sticks?
btw, I have to say that the Lenovo return mechanism which required me to talk to someone I could barely understand did not help. I used to love the Thinkpad line for its robust design (and had many), the T410s, which was not inexpensive, felt flimsy in comparison and having the screen die in such a short time is disconcerting (and seeing how many people are dealing with the same thing is a further concern).
Solved!
Go to Solution.

For the record: Technician came and replaced the LCD. Took maybe 10 minutes. Works perfectly now :-)
I asked him if he noticed anything about T410s displays failing and he was not aware of any issue with that particular model.

Key out vertical banding?

I just shot some phantom footage and the sensor was messed up in the field. There wasn't any way to reset the camera in the field without risking camera failure so I just had to go with having messed up footage over no footage at all. My question is, is there any way to "key" out these vertical banding lines in premiere/after effects to just essentially mask them out of the image? Thanks in advance

i dont have vertical lines but there's a darker spot when i tried to take pics on light coloured background. and the spot gets bigger and switches to another place when i tried to take video. it's definitely the camera coz i dont see the spot when i looked at the pictures i imported into the phone.
does that happen to anyone else?

Strange vertical bands on Starz HD

I'm seeing distorted vertical bands on the Starz HD channel, and it appears on all of the televisions in my household. Is it a problem with my ONT or a network issue?

Welcome to Apple Discussions!
This sounds like it could be a hardware problem either with the display or possibly the graphics chip. Since you are under Apple's 1 year warranty, the best thing to do would be to contact Apple and see what they recommend you do to have it repaired. I don't know what the resources might be in Kenya, but if you bought it locally, perhaps the store where you bought it could be of help.
Good luck!

Vertical banding in KDL60W630B

Overall the colors and image is quality of this TV is good. However, in the scenes with solid background colors (like the sky), the vertical bands become visible when the camera pans horizontally. I'm trying to decide if this particular TV is defective or if all the Sony KDL60W630B has this issue... Here's the picture of my TV with vertical banding (you might need to copy and paste the link below, clicking on it seems to be not working) http://bestbuy.ugc.bazaarvoice.com/3545w/279626/photo.jpg Thanks.

Vertical bands on my 17" LCD

Something very odd happened to my 17" LCD this morning. Instead of the usual picture-perfect clarity, I have vertical bands or stripes across the screen. They vary in color from white to grey to blue to black and vary in width. There is no hint of what should actually be displayed on the screen (i.e., the login window for my G4 cube). Also, the outside 1 or 2 inches of the screen is black, as if the screen has a cataract that has blurred the peripheral part of the screen. I've tried rebooting, but no luck. I connected the G4 cube to a different screen and it's working fine, so it's definitely the monitor at fault. This monitor has been connected to this same G4 cube for about 5 years without issue. Has it just reached its lifetime limit? Any suggestions for a potential fix will be most appreciated.

A second purple line appeared along side the blue/green one. These discussions show a problem exists with these lines on their displays, and although they made no acknowledgement of this, The Apple Store replaced the LCD in record time, although I was told at first I would have to wait a month for a new LCD. A new logic board was tried first but did fix the LCD, adding two hundred megabytes of data to my hard drive for diagnostics. I recloned my hard drive to clean it out. Without Apple Care (I'm half way through the three years) this would have cost $700 or more.

Black & White Vertical Bands on Freeze

For the past few weeks my eMac has been randomly freezing and the display is filled with thick black & white vertical bands/lines. The applications seem to be running in the background when this happens (iTunes was still playing) but I have to hold the power button to shutdown the computer as it won't display anything on screen other than the black & white bands.
Does anyone know what this is/how I can fix it?
Thanks

The symptoms you describe of one of a set of many which may indicate that your eMac 1 GHz or 1.25 GHz machine uses a logic board on which there are defective capacitors.
To determine if this is the case with your logic board, you may remove the user access place on the underside of your machine and inspect the visible capacitors. Affected boards typically will show evidence of swelling, bloating or leakage of fluid from the capacitors.
While Apple once covered the replacement of such logic boards, the repair extension authorization for this issue expired long ago. You can alternatively have your logic board repaired if it is affected by this defect. Contact me at the electronic mail address listed in my Public Profile if you are affected and want to explore such an alternative.
