Bright Screen/Washed out colour!!!

I have an imac g4 which has the same symptoms as an earlier post, ie. an overly bright and washed out display. My hunch is that it could be a loose wire somewhere. The fault developed after it was in transit, it was in all its original packaging.
Has anybody else had this problem? If so what is the remedy???
I'd rather have a go myself than get ripped off!!
Imac g4 Mac OS X (10.2.x)

Hi guys,
Thanks for your input!
Here's and update... i downloaded the service manual on the page you directed me to a few days ago, it's very interesting. I've formatted the harddrive and re-installed OS 10.1.
I still have the same problem!
I reset the PMU, this had no effect.
I took the bottom off and checked the video cable, i also checked the cables in the monitor. I did this a couple of times to make sure, powering on and checking each time! Still the same problem!!!!
The universal access has no contrast setting, altering the colorsync profiles hasn't had any effect.
The next step in the manual is to replace the inverter, could this be the cause??
Not sure what happens when the inverter malfunctions, does anyone know?
Are Apple parts expensive? I should have stuck with my trusty PC!

Uneven brightness + washed out colours

I got a new iBook G4 12in a week ago. Love everything about it apart from the screen. As soon as I booted it for the first time I noticed the screen wasn't particularly bright and that the colours were washed out. It's usable but not of a level I'd expect from Apple. It's bad even under standard office fluorescent lighting.
A colleague with an identical iBook noticed my screen was a bit dim and said he usually runs his iBook at a low brightness level (two notches off bottom). If I did that on mine, I'd struggle to see anything! It has to be run at full or just below full brightness to be usable.
I've also noticed that the bottom of the screen is brighter than the top. This took me a week to notice so isn't a huge problem. At the bottom corners there are very light streaks - it's a bit like the screen is being run from two halogen spotlights placed underneath the plastic surround!
Should I phone Apple's support and get this fixed, or is it to be expected? Research online shows half the people have a similar problem with washed out colours, while half claim their screens are bright and vibrant.

I called AppleCare last night. First, the guy asked me to do a couple of adjustments. He suspected that the display was damp. So he asked me to turn off the system, take out the battery, and then discharge the whole machine completely by pressing Shift, Ctrl, Alt, and the power button at the same time. But this trick didn't solve the problem. Second, he asked me to put the installer cd in and adjust something. It didn't work either. After this, he got me a system engineer on the phone, and he said there were two options: I could either send it in for repair, which would be quicker, or exchange it for a new unit, which would be slower, about 10-12 days. So I decided to exchange it for a new one. They are sending me the packing labels. Then I will send this one back. They will send a new one to me.
I suspect that displays with such problems are recycled ones. I mean they are taken from junk ones with an okay display. I hope this is not true. The display on my three-year-old Compaq still looks better than this one.
Apart from this small defect, my new computer works really well, and I love it. I am just a little disappointed with the product quality of Apple computers. It seems that they have put a lot of effort in the design of the appearance of their computers. But there is some degree of negligience on other aspects of their computers. That's why this forum is full of complaints.
Personally I think it is better to buy a computer directly in a store. It is easier to return or get a new one.

Why does the screen "wash out" with the statement "Firefox is not responding" This happens at least once in each session.

I am not sure what more details I can provide. Suddenly, the cursor for the mouse will freeze, the screen washes out. You can still see the underlying webpage faintly. After a few seconds, the problem corrects itself and Firefox resumes normal operation. This happens with the new Firefox 4 as well as the previous version.
It is major annoyance.

My situation got worse. FF 3.6.12 started doing that; then it just stopped loading. Since then, I have uninstalled & reinstalled, moved my profile to force it to make new one, set it so that it is not the default browser, installed in different drive on computer, cleaned out regedit, ran a spyware program, & nothing. It starts to load then hangs up almost immediately. This has been going on for about 3 days & I'm about ready to chunk it. Any ideas?

IMac 24" with washed out colours - Help!

My iMac 24" Aluminium (June 2008) running 10.5.8 has behaved impeccably for almost two years. I use it for graphics and photographic work, so colour fidelity is very important.
A few days ago, in the morning, the machine was still "perfect". By lunchtime I realised something was not right. The Photoshop file I had been working on looked different. I could not see details in highlights, transparency in layers that was clearly there in the morning had suddenly vanished. Looking closer at the whole screen I realised the whole environment was washed out - not just in Photoshop files.
I tried:
Calibrating the monitor - no difference.
ColorSync Utility: Verify/repair - reported loads of errors but fixed nothing.
Took the mac to authorised Apple repair shop in Hove (UK). Spent time with the engineers trying to sort it out. They had not experienced this before.
We connected 2nd monitor. Strangest thing: The same moment the 2nd monitor was connected, the native screen instantly looked fine. Both monitors fine.
Disconnecting 2nd monitor, and the native screen went bad again.
Booted up the iMac with their external drive and system (sorry, not sure which system but probably the same 10.5.8). The screen looked fine, even without a 2nd monitor. Rebooting with native OS and the screen went bad again.
Conclusion: Corrupt file in the system somewhere. Advice: Reinstall system (archive/install).
I did this today. Screen is the same bad screen, so reinstalling 10.5.2 and upgrading to 10.5.8 did NOT solve the problem. Erase and install is my VERY LAST resort. I really don't want to start from scratch with new system, new installation of applications, updates, settings etc.
I would rather buy a small 2nd monitor, watch the screen look good again, having another screen to use and PRETEND I DON'T HAVE A PROBLEM!
I also ran an extended hardware test (from OSX 10.5.2 install DVD) without reporting any problems.
Questions:
Has anyone any idea what this can be?
Is it possible that upgrading to Snow Leopard can solve the problem (but that is also just an upgrade and not a clean start?)
One way of describing it is that a finder window has no contrast in highlights (blue and white horizontal stripes are only visible when another window's drop shadow multiplies with the background. Everything is too bright, banding appears in visible highlights.
Someone suggested moving the file /Library/Preferences/com.apple.windowserver.plist to trash, without deleting yet. Then reboot.
It didn't work.
Thanks for any help!

My problem was purely about screen contrast, not the colours. It was in fact me accidentally keying the shortcut (key command was unknown to me then) for contrast settings that are found in System Preferences -> Universal Access > Seeing, Display: Enhance Contrast. The key command is also shown there.
I now realize that I did this key command when working in Quark XPress which has a very similar command: "Shift-Option-Command" and then "," or "." I accidentally keyed "Control-Option-Command" and then "." Worth being aware of if you're working with Quark.
Glad your problem was solved by calibrating your monitor.

H.264 gamma shift/washed out colours on export

I know this has been discussed before but I've been researching this topic for the past two hours and still can't find a solution.
I have .mov source files from a Canon 7D. Exporting them from PP CS5.5 (Mac OS X - Lion, 10.7.4) in h.264 or by 'matching sequence settings' results in a gamma shift/desaturated colours. Playing the resulting h.264 file in QuickTime Player, VLC, Elmedia all result in the same colour shift so this is not an issue with QT simply interpreting the gamma incorrectly.
Uploading to Vimeo and Youtube results in the same gamma shift. The monitor I'm using is not calibrated but when puling up a VLC window of the exported file next to the Program Monitor (on the same monitor) shows that there is a definite difference. Below is a screenshot.
Is there any way to produce an exported file for Vimeo use that reproduces the gamma as I see it in the Program Monitor?
Any help would be massively appreciated.
Thanks.

Did you use Quicktime's H.264 export option? Or just standard h.264 using the .mp4 container? If you used the Quicktime h.264 the option itself is flawed. Here are some links regarding the issue.

If you read around the net a lot of people have had this issue with h264. A couple of the articles I posted are supposed to "fix" the problem although I haven't ever tried any of them myself. I've never experinced a gamma shift when using the standard h.264 format option in Premiere, however if you have already used that option and you're still having issues then I have no clue what is going on. However when I import ProRes files into Premiere they don't appear washed out, but when I play them in Quicktime or VLC they do appear washed out. I've always just assumed Premiere was somehow correcting it, because when I export my video to mpeg-2 for playback on our server it looks like it looked in Premiere.
From what I have read though the reason the Quicktime format does this when using the h.264 codec looks and looks washed out is because of a incorrect gamma tag. But Premiere isn't affected/fooled by this like most media players are. According from how they made it sound on provideo and the one other site I read it on anyways.

Washed out colours

Can anyone please tell me why the colours on this image look completely washed out. Taken with Canon 30D set on sRGB, original RAW imported into LR with ProPhoto set as working space. Exported as jpeg and resized in Photoshop. Note: the colours were washed out upon Export and appeared so whether later Imported back into LR and viewed, or viewed with other applications. The yellow alone should be very vivid and bright as Rape seed is and not a dull green as shown here :-(
http://community.dcmag.co.uk/photos/alan_inghams_gallery/images/420895/original.aspx

First off - many thanks to all those who have taken the time to view this post and likewise have offered many many suggestions - I am indeed beholding to you all.
Jeff - my monitor was in fact calibrated only this morning in my efforts to eliminate every possible problem area.
Tonight I have done what many have done - I 'Exported' the RAW file using the Export function in LR. In fact I exported twice, once as a jpeg and once as a tiff. I then 'Imported' both back into LR and as others have observed, when compared to the original RAW file the tiff and jpeg look almost identical. Exercise also repeated in CS2 with same results.
However, has anyone tried viewing the tiff/jpeg image OUTSIDE of LR e.g. I have viewed them using Windows Explorer, Windows Picture and Fax Viewer and Fastone Max Viewer. It is when viewed in these applications that the images (jpeg and tiff) looked flat and washed out.
So my concern is plainly obvious. I know that I can upon Import always see favourable results of all the images (RAW, TIFF and JPEG) within LR itself. But I do not want always to view them in LR - I also want to sent the resultant TIFFs and JPEGs to a web situated printing company. I am concerned that the prints will be returned flat and lifeless as they appear in other applications. This is something I won't know of course until I actually send a print away for printing.
Could those kind people who have taken the trouble thus far and 'Re-Imported the tiff/jpeg back into LR please have a look at it OUTSIDE of LR e.g. using Windows Explorer if approriate and tell me do they still see the same results as when the images are in LR or CR3. I might be labouring this point, but it is not enough that they all appear colourful and pretty etc whilst in LR or CS3 - they actually have to leave the applications at some time or other. The only good news in this story so far is that when I printed out the original RAW image from within LR the print did in fact turn out OK :-)

Washed out colours in DVD SP, but not in iDVD?

I was using iDVD to burn my projects and decided to go pro and use DVD SP 4 at work. I had some help putting the project together and burnt off a DVD. All works fine, but the colours are definately more washed than when I burnt the same quicktime through iDVD 6.
The footage was captured from PAL DIGI Beta, using the blackmagic capture card and codec and used uncompressed in both projects.
Even the title screen of the DVD SP project is washed out compared to the iDVD one. I've viewed both DVDs on an LCD imac and a CRT sony trinitron.
Any ideas?
Powerbook G4 Mac OS X (10.4.9)

I am not sure if the two applications encode the same - iDVD may use different settings to encode the video when compared to the settings in DVD SP or using Compressor which can change the output/how it looks - that may be what is happening.
You can take the exact same movie and place it in different encoders, or the same encoders with different settings, and the end result will look different.

T410 Screen Washed Out on Wake

Hello,
I was wondering about an issue that I've been having... sometimes when the computer wakes up from standby (on battery power only) the screen colors become very washed out, but eventually fade back to normal. Is this a normal occurrence with the T410 screen, or is it something that I should be concerned about? Otherwise, the T410 seems to be a very solid computer.
Solved!
Go to Solution.

Never mind, I solved my problem, it is normal: http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T410-unstable-screen-brightness/td-p/212150

Lightroom's interpretation of camera raw data washes out colours

After I import images from my Canon 5D, they look different when I go into the develop module. I read the FAQ and I understand that this is caused by the difference between the stored thumbnail on the camera and the way lightroom interprets the raw image data.
The problem is, the tone and colour are always far superior in the camera thumbnail interpretation, and I spend considerable time on Lightroom to try and get the image back to how it originally looked on the camera thumbnail, usually unsucsessfully.
Is there a way I can get lightroom to match exactly the look of the previews stored with the raw file on the camera?
It is a big problem, because after lightroom interprets the data, skin tones look washed out and the colours are not as rich or natural looking.
I don't have this problem on other raw converters, and it is making me look for another software solution if I can't resolve the problem.
Help!

Well, my eyes must be doing some wonky things then... because in my experience its LR that is cheating me on the colors.
Yes... Canon many times oversaturates the colors... but I'm pretty sure that those red cherries I took a picture of were not pumpkin orange as LR shows them. ACR has some serious hue shift problems, yet not for everyone... it varies from camera model to camera model, and even within camera model from camera to camera.
The best we can do, since ACR isn't intelligent enough, is to fiddle with the calibration settings, and save that as the new default for the camera. (There are scripts that help do this if you have a Color-checker and CS2/CS3... but are of no help if you use only LR or Elements.)
Never expect the default settings in RAW (for ANY converter... Canon's included (with execption, perhaps of Zoombrowser)) to match the preview you see on the camera, or the out-of-camera jpeg. Adjustments will need to be made. Unfortunately in ACR, this means hours of messing the calibration sliders, much trial and error, and perhaps multiple presets to help with different lighting conditions.
That said... I too would like to see ACR improve in this area... but for the mean-time this is the best we can do.
edit: (I'm (slightly) exagerrating the extent of the shift above... but its VERY noticable... and can be very frustrating.
This site: http://www.photoactivity.com/Pagine/Articoli/023%20Calibratori%20al%20sole/Calibratori%20 al%20sole_en.asp explains in more detail than I understand some of the calibration scripts... and even has some screenshots of a color-checker comparing ACR defaults and various scripts to the color-checker. I'd guess the shifts I see are comparable to some of those shifts seen on that page.)

Imported RAW Photos too bright (overexposed, washed out)

I've noticed with my Sony A700 camera that when I import RAW photos into aperture they look alright in the jpeg preview but once they are processed as raw they become extremely washed out and bright, does anyone know how to fix this?

I have noticed the same issue with my A700 cRAW images. I just got Aperture 3.0.2. I guess I will play around with the raw fine-tune brick to strike a balance with properly exposed image quality, but it's uncomfortable when your preview image and histogram appear good, and your imported image is washed out.
Anyone have a better preset for the A700 camera?

FCP Filter control brightness? - washed out - too bright?

We filmed a high school jazz choir presentation, 4 -HD canon HFS 20 cameras. We had the white balance set to incandescent. The video was edited using multiclip. It all looks very good, on all the close up cameras. The wider shots look a little washed out or too bright. The lighting on the stage was pretty bright, so if a student had a white shirt on and the lights were directed at his/her head, it kind of blended together slightly. In general it looks pretty good, but I was wondering if there was a way to cut that (overexposure?) down using FCP, or is there something I need to do when we film.

Hello Jeff,
generally you should avoid overexposing your footage. Most cameras have a "Zebra" that will indicate areas over 100 IRE. Blown out video may not be fixable in post because the information in the overexposed areas may be lost. You can try the following:
• 3-way color corrector; easiest approach but not very powerful
• take the footage into Color for grading; this is much more sophisticated as you can work on selected areas.
• if you don't want go through Color you could give this tool a shot: http://www.pistolerapost.com/pluginz/captains.zip

N73 viewfinder washed out colours

Hi, just got my N73 with 3 X-Series silver.
Great phone but I'm finding that the viewfinder display seems to be washed out. It's fine for a split second when I first slide back the lens cover but then instantly appears washed out. It's almost like the N73 applies some sort of filter to the image. This behaviour is also evident when I flick through the white balance options - ie looks fine for a split second, then reverts to washed out look.
Incidently, if I preview a photo that I take, it appears fine. It just seems to be the "LIVE" display in the viewfinder.
Can anyone tell me if this is a fault or if it's a setting somewhere I can change.
For info I modified the light sensor setting and it didn't have any affect.
regards,
Shaka

Sounds to me as if your color profile (system preferences/displays/color) is off. Reset it to: lcd screen and see if that takes care of it. Not sure why your macbook doesn't remember that setting, though. In any case, it's less hassle to change it there than to reset the PRAM every time.
Hope this helps,

IMac 20" vs iMac 24" : screen WASHED OUT on 20"

I went to two Apple stores and I noticed that the new Aluminum iMac 20" SCREEN CONTRAST is set different from the 24".
I tried using two side by side 20" and 24" and I set the screen settings the same. But not matter what I did the contrast on the 20" was pretty bad. 24" was normal but the 20" was Washed out (when viewing photos, there's no detail in the highlight areas).
Anyone else notice this? Or it just me? I foun this at two stores I went to.

GREAT! I thought I'd read all of the down sides to the new 20" iMacs. How'd I miss this? Well, I knew that with the minor CUP speed bump made to the new iMacs and no "Extreme" option on the 20" I was about to take a beating down the road here...very shortly. That "shortly" is already NOW, I guess. My 20" screen was washed out using the iMac's display color setting, so I went into Preferences/Display/Color and played with the RGB profile settings. This helped a lot, but it made me wonder why Apple would have let it be shipped with their poor "iMac" color profile. Geez, I hope changing the setting, making the screen colors pop, won't burn out this monitor!!! GULP!!! If only our old Mac G4 tower hadn't died a few months back, we'd been waiting so long already and a 20" monitor looked big enough to us.
BTW, where are all of my Apple Loops in the preinstalled iLife '08 GarageBand? I just got this iMac yesterday. Time to do more digging!

Upgrade to 10.6.7 Fans full blast and Screen washed out

Update went well but after restart, the icons, finder windows, system preferences all look washed out. It is almost like they are 8 bit color not 24 bit color. At the same time the fans go crazy at login and then settle down later. Logged in with Safe Mode and it did not change anything. I reinstalled from Combo, still no joy. Any ideas?

Update: The fans seem to have settled down, maybe it was an update to Spotlight?
Screen still washed out. It looks like when you attach an external monitor and you do not have the cable fully set. In Finder, you don't see light gray lines, in Excel, you don't see the grid. You could also say that the resolution is not at "millions of colors" but at 256 or less.
