X220 IPS: latency of pixels too high - slow colour switchback

Sorry guys to present you with a new problem concerning the X220 but I noticed today (only half an hour ago) that if I switch my screen to a black screensaver and wait around 15s and go back to normal screen then the colours will be "unreal" -> means they appear to bright and "undetailed" for some time (15 to 20s) and then go back to normal (it's like slowly increasing colour depth from 256k to 32bit or the latency of the all pixels is to high).
To literally talk in pictures: I have one of these standard "I-come-with-windows-please-use-me"-background pictures of a koala. In normal state I can the details of its fur. But if the I do the above the Koalas fur is more like a big grey surface.
Sadly, I couldn't capture the phenomena with a screenshot (I tried several times but no luck) so it seems to me more like a hardware issue (have an IPS panel but so far had no problem with ghosting. but I have the screen bleeding.). Also because it's late and quite dark here in Germany I can't take a good photo of it.
If a Lenovo employee should read this here are some more hints for debugging: Have a recently bought X220 (Type: 4290-W1B) and it's currently running on battery (haven't checked plugged-in yet because I'm dead tired but hopefully will have time tomorrow) with brightness level 5 (changed it to max of 15 but problem is still occuring).
Please tell me if you need more informations! And thanks for your help beforehand.

My latency seems far too high.

Like many others here, I primarily use my internet connection for gaming, now along the way over the past few years with BT I've never had the best connection but for a long time my ping was normal.
A couple of months ago my internet was upgraded, maybe it was something to do with the nearest exchange, I'm not sure, it wasn't an upgrade I asked for, mind. We were given the brand new homehub as well.
So the upgrade went something like 1mb - > 4.5mb. Can't complain too much, better download speeds and what not. The biggest gripe I have, that is when this upgrade occurred, my latency sky rocketed from about 15-20 to 35-40 (average) on UK servers.
It's pretty **bleep** annoying to say the least, because when I connect to other european servers it's almost unplayable and I play on servers outside of the UK the most. I rang up BT to ask for interleaving to be turned off, as usual they pretended they didn't know what it was and ignored me. So what can I do, anything? Doesn't seem right that I get 40ping to a UK server, when most of the country sits on about 15ping.

If you place in Muse - an image with either height or width larger than 2048 pixels - Muse scales the image down proportionately, limiting the larger dimension to 2048.
However, if you want to use the placed image at its original size, you can scale the image up to desired size either by dragging the resizing handles or by entering Height and Width values in the Control Strip on top. After that, go to the Assets panel and locate the image in there, then right click that image in Assets panel and choose "Import Larger Size". That would bring back the lost image information from the original image.
Hope this gives you clarity on what you wanted to know.

Disk Transfer (reads and writes) Latency is Too High

i keep getting this error:
the Logical Disk\Avg. Disk sec/Transfer performance counter has been exceeded.
i got these errors on the following servers:
active directory
SQL01 (i have 2 sql clustered)
CAS03 (4 cas server loadbalanced)
HUB01
MBX02(Clustered)
a little info on our environment:
*Using SAN storage.
*Disks are new ,and working fine
*the server has GOOD hardware components(16-32 Gb RAM;Xeon or quadcore........)
i keep having these notifications everyday; i searched on the internet and i found the cause to be 1 of the 2:
1) disk hardware issue( non common=rarely )
2) the queue time on the hard-disk( time to write on the Hard-disk)
if anyone can assist me with the following:
1) is this a serious issue that will affect our enviroment?
2) is it good to edit the time of monitoring to be 10minute(instead of the default 5min)
3) is there any solution for this?(to prevent these annoying -useless??--- notifications)
4)what is the cause of this queue delay;;and FYI sometime this happens when nothing and noone is using the server (i.e the server is almost Idle)

The problem is.... exactly what the knowledge of the alert says is wrong. It is very simple. Your disk latency is too high at times.
This is likely due to overloading the capabilities of the disk, and during peak times, the disk is underperforming. Or - it could be that occasionally, due to the design of your disks - you get a very large spike in disk latency... and this trips the
"average" counter. You could change this monitor to be a consecutive sample threshold monitor, and that would likely quiet it down.... but only doing an analysis of a perfmon of several disks over 24 hours would you be able to determine specifically
whats going on.
SCOM did exactly what it is supposed to do.... it alerted your, proactively, to the possible existence of an issue. Now you, using the knowledge already in the alert, use that information to further investigate, and determine what is the corrective
action to take.
Summary
The Avg. Disk sec/Transfer (LogicalDisk\Avg. Disk sec/Transfer) for the logical disk has exceeded the threshold. The logical disk and possibly even overall system performance may significantly diminish which will result in poor operating system and application
performance.
The Avg. Disk sec/ Transfer counter measures the average rate of disk Transfer requests (I/O request packets (IRPs)) that are executed per second on a specific logical disk. This is one measure of storage subsystem throughput.
Causes
A high Avg. Disk sec/Transfer performance counter value may occur due to a burst of disk transfer requests by either an operating system or application.
Resolutions
To increase the available storage subsystem throughput for this logical disk, do one or more of the following:
â€¢
Upgrade the controllers or disk drives.
â€¢
Switch from RAID-5 to RAID-0+1.
â€¢
Increase the number of actual spindles.
Be sure to set this threshold value appropriately for your specific storage hardware. The threshold value will vary according to the diskâ€™s underlying storage subsystem. For example, the â€œdiskâ€ might be
a single spindle or a large disk array. You can use MOM overrides to define exception thresholds, which can be applied to specific computers or entire computer groups.
Additional Information
The Avg. Disk sec/Transfer counter is useful in gathering throughput data. If the average time is long enough, you can analyze a histogram of the arrayâ€™s response to specific loads (queues, request sizes, and so on). If possible, you should
observe workloads separately.
You can use throughput metrics to determine:
â€¢
The behavior of a workload running on a given host system. You can track the workload requirements for disk transfer requests over time. Characterization of workloads is an important part of performance analysis and capacity planning.
â€¢
The peak and sustainable levels of performance that are provided by a given storage subsystem. A workload can either be used to artificially or naturally push a storage subsystem (in this case, a given logical disk) to its limits. Determining these
limits provides useful configuration information for system designers and administrators.
However, without thorough knowledge of the underlying storage subsystem of the logical disk (for example, knowing whether it is a single spindle or a massive disk array), it can be difficult to provide an optimized one size fits all threshold value.
You must also consider the Avg. Disk sec/Transfer counter in conjunction with other transfer request characteristics (for example, request size and randomness/sequentially) and the equivalent counters for write disk requests.
If the Avg. Disk sec/Transfers counter is tracked over time and if it increases with the intensity of the workloads that are driving the transfer requests, it is reasonable to suspect that the logical disk is saturated if throughput does not increase and
the user experiences degraded system throughput.

Are JPEG 3504x2336 pixel pictures too high resolution for the photo books?

Hi,
I am done creating my photo book and I am ready to order, but I'd like to know if my pictures are too high resolution. They are professional wedding pictures so they are 7.4 mb each JPEG 3504x2336 pixel pictures. (Last time, I printed through MyPublisher but the pages with multiple pictures didn't turn out well and they said it was because the resolution was too high so when they compressed the file for the pages with multiple pictures it didn't turn out well.) Will I run into the same problem if I print directly through Iphoto?
If I do need to lower the resolution, how do I do it, given that I've aready created the book?
Thanks for any help you can give me!

Welcome to the Apple Discussions.
When you order the book it will be compressed and a PDF will be created. That PDF is what gets uploaded to Apple (via Kodak) for printing. So the best way to check your book before ordering is to create a PDF, then inspect it. Chances are, what you see in your PDF is what you will get printed.
To do this, select your book and do File > Print. You'll get an "Assembling book" progress bar. That can take several minutes. When done, you get the Print Dialog box. Click the PDF button and choose "Save as PDF..." Choose a name and location for the file (the Desktop is convenient) and Save. Then switch to the Finder and open that PDF in Preview. You might select a page or two and do a test print yourself, to see if the quality looks good. The PDF saves you from having to print out the whole book yourself to check for errors.
Regards.

PGC...data rate too high

Hallo,
message
nunew33, "Mpeg not valid error message" #4, 31 Jan 2006 3:29 pm describes a certain error message. The user had problems with an imported MPEG movie.
Now I receive the same message, but the MPEG that is causing the problem is created by Encore DVD itself!?
I am working with the german version, but here is a rough translation of the message:
"PGC 'Weitere Bilder' has an error at 00:36:42:07.
The data rate of this file is too high for DVD. You must replace the file with one of a lower data rate. - PGC Info: Name = Weitere Bilder, Ref = SApgc, Time = 00:36:42:07"
My test project has two menus and a slide show with approx. 25 slides and blending as transition. The menus are ok, I verified that before.
First I thought it was a problem with the audio I use in the slide show. Because I am still in the state of learning how to use the application, I use some test data. The audio tracks are MP3s. I learned already that it is better to convert the MP3s to WAV files with certain properties.
I did that, but still the DVD generation was not successful.
Then I deleted all slides from the slide show but the first. Now the generation worked!? As far as a single slide (an image file) can not have a bitrate per second, and there was no sound any more, and as far as the error message appears AFTER the slide shows are generated, while Encore DVD is importing video and audio just before the burning process, I think that the MPEG that is showing the slide show is the problem.
But this MPEG is created by Encore DVD itself. Can Encore DVD create Data that is not compliant to the DVD specs?
The last two days I had to find out the cause for a "general error". Eventually I found out that image names must not be too long. Now there is something else, and I still have to just waste time for finding solutions for apparent bugs in Encore DVD. Why doesn't the project check find and tell me such problems? Problem is that the errors appear at the end of the generation process, so I always have to wait for - in my case - approx. 30 minutes.
If the project check would have told me before that there are files with file names that are too long, I wouldn't have had to search or this for two days.
Now I get this PGC error (what is PGC by the way?), and still have no clue, cause again the project check didn't mention anything.
Any help would be greatly appreciated.

Christian Kirchhoff

Hallo,
thanks, Ruud and Jeff, for your comments.
The images are all scans of ancient paintings. And they are all rather dark. They are not "optimized", meaning they are JPGs right now (RGB), and they are bigger then the resolution for PAL 3:4 would require. I just found out that if I choose "None" as scaling, there is no error, and the generation of the DVD is much, much faster.
A DVD with a slide show containing two slides and a 4 second transition takes about 3 minutes to generate when the scaling is set to something other than "None". Without scaling it takes approx. 14 seconds. The resulting movies size is the same (5,35 MB).
I wonder why the time differs so much. Obviously the images have to be scaled to the target size. But it seems that the images are not scaled only once, that those scaled versions of the source images are cached, and those cached versions are used to generate then blend effect, but for every frame the source images seem to be scaled again.
So I presume that the scaling - unfortunately - has an effect on the resulting movie, too, and thus influences the success of the process of DVD generation.
basic situation:
good image > 4 secs blend > bad image => error
variations:
other blend times don't cause an error:
good image > 2 secs blend > bad image => success
good image > 8 secs blend > bad image => success
other transitions cause an error, too:
good image > 4 secs fade to black > bad image => error
good image > 4 secs page turn > bad image => error
changing the image order prevents the error:
bad image > 4 secs blend > good image => success
changing the format of the bad image to TIFF doesn't prevent the error.
changing colors/brightness of the bad image: a drastic change prevents the error. I adjusted the histogram and made everything much lighter.
Just a gamma correction with values between 1.2 and 2.0 didn't help.
changing the image size prevents the error. I decreased the size. The resulting image was still bigger than the monitor area, thus it still had to be scaled a bit by Encore DVD, but with this smaller version the error didn't occur. The original image is approx. 2000 px x 1400 px. Decreasing the size by 50% helped. Less scaling (I tried 90%, 80%, 70% and 60%, too) didn't help.
using a slightly blurred version (gaussian blur, 2 px, in Photoshop CS) of the bad image prevents the error.
My guess is that the error depends on rather subtle image properties. The blur doesn't change the images average brightness, the balance of colors or the size of the image, but still the error was gone afterwards.
The problem is that I will work with slide shows that contain more images than two. It would be too time consuming to try to generate the DVD over and over again, look at which slide an error occurs, change that slide, and then generate again. Even the testing I am doing right now already "ate" a couple of days of my working time.
Only thing I can do is to use a two image slide show and test image couple after image couple. If n is the number of images, I will spend (n - 1) times 3 minutes (which is the average time to create a two slides slide how with a blend). But of course I will try to prepare the images and make them as big as the monitor resolution, so Encore DVD doesn't have to scale the images any more. That'll make the whole generation process much shorter.
If I use JPGs or TIFFs, the pixel aspect ratio is not preserved when the image is imported. I scaled one of the images in Photoshop, using a modified menu file that was installed with Encore DVD, because it already has the correct size for PAL, the pixel aspect ratio and the guides for the save areas. I saved the image as TIFF and as PSD and imported both into Encore DVD. The TIFF is rendered with a 1:1 pixel aspect ratio and NOT with the D1/DV PAL aspect ration that is stored in the TIFF. Thus the image gets narrowed and isn't displayed the way I wanted it any more. Only the PSD looks correct. But I think I saw this already in another thread...
I cannot really understand why the MPEG encoding engine would produce bit rates that are illegal and that are not accepted afterwards, when Encore DVD is putting together all the stuff. Why is the MPEG encoding engine itself not throwing an error during the encoding process? This would save the developer so much time. Instead they have to wait until the end, thinking everything went right, and find out then that there was a problem.
Still, if sometime somebody finds out more about the whole matter I would be glad about further explanations.
Best regards,
Christian

Video bit rate too high - reducing doesn't help

I've not come across this problem before. Now DVDSP tells me my vbr is too high, but reducing it gives me the same message. I'm attempting to put 47mins of SD onto a DVD-R, so not outrageously demanding. I'm not sure where to go from here.

John Howarth wrote:
My problem is happening on a talking head - there is plenty of movement elsewhere in this movie, and that is all compressing correctly. When I reach this particular clip, which has very little movement, the glitches happen when the guy moves his head. It happens nowhere else in the whole 87 mins, and it happens repeatedly on re-encodes in the same clip - not precisely the same frames, but the same clip. Exporting the clip and its neighbours alone, and compressing it, presents no problem when written to a DVD-R
It is strange, so in other words if Clips A, B, and C are all in one movie from Final Cut then the encode shows the problem in Clip B, let's say, but if you break down each section and drop each encoded clips (A,B,C) on a timeline in DVD SP then it looks okay? You mention that it is not the same frames each time, but are they near where the cuts/changes occur or is it throughot the entire section? Could be the encoder or perhaps the DVD Player is getting tripped up there. I have placed Compression markers in problem areas, even if not scene changes or high movement, to help when I had some ghosting with relatively slow rates of movement. I have not had to do it often, but it helped.
Though I think it is probably not related to the following, how many players have you tried it on and which brand of DVD Media are you using? Do you see the same problem when playing from the hard drive in Apple DVD Player and/or the DVD-R in Apple DVD Player? How are you burning the DVD? Straight from DVD SP or otherwise? (You are using the Universal Binary version of DVD SP and Compressor I take it?)
These problems all occur when using Compressor, at 6.2Mbps preset, with ac3 for the sound. Is that just too high? But then why does the rest of the movie play OK?
It probably is not too high if everything else is okay, and more so it sounds like it is a place where there is not much movement. Moving his head should not throw things that far off. Did you mix clips/camera types in Final Cut? When you say glitches, what is happening, macroblocking, skips in playback, jerky movement? Ghosting?

Gradient banding on X220 IPS screen

Over on the Faint Ghosting on X220 IPS screen thread, I mentioned (twice, actually) that I see gradient banding on my X220 IPS screen. Nobody else has brought up this issue, and at the moment it seems that I may have a defective screen.
Here's a test image to check for gradient banding: http://www.lagom.nl/lcd-test/gradient.php. View and compare how it looks on other laptop and desktop monitors. Gradients appear smooth on my desktop PC (Dell monitor and low end Radeon card) and MacBook Pro, but banding is easily visible on my X220 with IPS screen. I even see faint banding when I view this forum, the subtle gradient background at the top of each post. My display is set to 32 bit color and 60 Hz refresh.
I'll take it up with Lenovo support. Meanwhile, anybody else who has the issue can post and discuss here.

I have the exact same problem.
When there is a gradient (like on the login screen, or the webpage linked earlier) I can see the image moving for a couple of seconds. This kind of behavior from the screen also makes my eyes painful after a while.
I love this laptop otherwise, but this is a terrible quality issue. I tried to explain my problem to lenovo with no luck.
Anyway, from what I read here, it's common to most x220, what can I do.
If at least lenovo was helpful. Or if they could let me return the laptop without the absurd 15% restocking fee...
Edit: Alright, found by myself after a couple of hours searching: The moving bands when the display is "adjusting" to the new picture is in part due to Intel's power saving tech "Intel Display Power Saving Technology" which can be disabled in intel's control panel. It causes flickering of the screen in general, but mostly gradients.
For those wondering, yes, it does save some power. The computer idling with this feature uses 10 watts. Without it's 11. I don't know how it'll affect battery life, but if I really need longer battery life, I'll turn the brightness down myself.
I still notice some flickering, I'll see how it goes. The banding, while now static, is still clearly visible though.
Maybe someday they'll learn LG is not good at IPS screens (see the ipad2 fiasco too)

Bit rate too high DVDSP, build stops.

DVD Studio Pro used to be DVD Maestro from Discreet, but I was thinking since Apple bought it long ago, it would have a forum. I searched for DVD and DVDSP and only came up with this forum.
If anybody in here uses DVDSP and if you know the solution I would appreciate help with this.
Upon building this, I did lower the bit rate to a lower size after getting the error message.
As of now I have the BR between 4.2 and 5.2 as the max br.
I'm concerned if I lower it anymore it will start looking like a pixelated mess. Does anybody know how low you can take the rate and still have a good looking project?
The project was taped in HDV. However I encoded it using compressor so I don't think it's an HD file anymore that DVDSP can't read. In the settings you'll see "SD".
I'm using DVD Studio Pro 4.
The settings I used for compressor were:

Are these settings too high?

All I did was click on the Performance 3D in the settings of Clock Frequencies of my FX5600 128MB. I then clicked on Auto detect and it changed my settings all by itself. I did not manually move any of the sliders.
My Core Clock Frequency for 2D is now 270MHz and 3D is 372MHz.
So far, America's Army plays way better and I was even able to bump up many of the games settings too.
Are these settings too high?

Both, but primarily the GPU will generate the most heat, either way, heat is a killer no matter how you look at it. Even if it is warm to the touch, that does not mean it's harmless. If it's warmer than the component manufacturer specs indicate, it shortens the life. As to the rate in which heat above a certain range actually shortens the life is better left to an electronics engineer or a spec sheet.
Do not overclock in 2d mode it's not necessary.
Probably not an issue if you have good cooling in your case and the ambient room temp is respectable.
If you want to overclock, let the 3d detect set it initially and then take the overall speed and reduce it by 5% or so. You may not notice failure right away if your eye is not trained to see the problems. So it's best to be conservative if you are not an experienced overclocker.

[DVDSP3] Bitrate too high ??? what can i do more ?

Hello,
i have a problem with a DVD . Total 3,9 GB, all tracks are M2V (exported from Premiere), all audio files are AC3... and i still got a bitrate too high ..
What can i do ?? the poorest bitrate is still too high .....

ok. i have tried with replacing all the video files .. new export from the original AVI files;
My parameters (Compressor) are : (in french sorry)

Still the same problem

I rendered an h.264 m2ts file at 17M bitrate, why Encore says bitrate is too high?

I rendered a h.264 m2ts file at 17M bitrate, why Encore says bitrate is too high?
17M is so low, so I have to render an AVI file and import it to Encore and let Encore transcode it, bitrate can be set to 40M, why? Encore's transcoding is toooo slow!
I rendered the m2ts files use Edius.
Help!
Thanks everyone!

Thank you Stan Jones!
I had set Maximum Audio/Video Bitrate to 40Mbbps in Project Settings' Default Transcode Setting dialog, and my Authoring Mode is Blu-ray. Things did not change.
But my m2ts file should be set to "Don't Transcode", so the values of transcode settings should not affect my m2ts file.
I've just find one thing: it seems that m2ts files rendered by Edius 5 will not work well in encore, while Edius 6's work better. I test some Edius 6's m2ts files over 30Mbps, it work. Is there something wrong with Edius or Encore?

VBR too high issue

I am using OS 10.3.9 and Compressor 1.2.1
I have a project right now that requires 3 multi-angle video tracks that are 40 mins. each.
I made sure they are all the same identical length. Set in & out points exactly the same for each track in FCP and created my own preset within Compressor to have the same Average and Maximum Data Rates as the 120min High Quality Encode preset. I created my own preset because DVDSP says that GOP needs to be closed and the 120min Preset does not show that to be the case.
Well after spending almost all weekend encoding video (no thanks to a slow dual 1 gig G4) and spending hours designing my DVD menus, DVDSP says that the Bit Rate is too high! That makes me feel like bashing my computer with a baseball bat! I thought I did my research and even created 30 second tests to make sure it would work.
Does anyone have any suggestions to find out why my Bit Rate is too high? And what I can do in the future to make sure I have an acceptable bit rate so I don't waste another weekend?
Also, is there a Compressor update I might not know about that will work with the system I use?
Thank you for any advice.

I was totally wrong about the video.
The User guide is correct.
Audio however is a different matter with multi-angle.
The data rate of all the associated audio tracks add together.
Here is a post from Trai Forrester on an Apple Dvdlist.
The relevant audio details are at the end:

Subject: RE: Multiple video streams
Hi Pete and All,
The multiple angle video stream, unlike multiple audio streams in a
single track object, is interleaved. Playback of multi-angle flagged track,
"hop scotches" on the chosen angle, "jumping over" the "not playing" chunks
of video, "bound" within their own angle. The "about 10mbps" ceiling still
applies.
The 7mbps maximum limit for each separately encoded video element that
will make up the encoded multi-angle stream, is more of a function of
distance over time, and the inversely capable limitation of standard
hardware to jump over non playing sections, as the non-playing sections, or
total number of angles in the stream increase (distance to hop scotch).
So the 9 angle stream will still register on the bit rate meter, well
within the specs (7mbps, as the other streams aren't "playing").
Audio streams are different. Even non-playing audio tracks bit rates
must be included in the total.
Example:
9 video angles (each encoded at 7mbps) = 7mbps (only one angle can play at a
time)
8 Dolby stereo audio tracks @224 kbps = 1.792 mbps
Total bit rate for the Track = 8.792 mbps - Plenty of room left to try to
wrestle some subtitle streams out of Subtitler, and include them!
Take care,
