MacBook Pro :: Unibody - Dell 2408WFP Waking From Sleep And Washed Out Screen
Apr 6, 2009
I bought a new unibody Macbook pro in December and have had it linked to a Dell 2408WFP for 4 months now (dell monitor as primary monitor, macbook as slave via apple mini displayport to DVI adapter) and I am also using the dell USB ports to hook up my apple wired keyboard and logitech revolution MX mouse. Problems occurring ever since the beginning include: Occasionally the computer refuses to wake up either screen. It may flash blue and look like its going to come out of sleep (or monitor shut off) with no problems but then hangs. This is intermittent and I cant seem to trouble shoot what causes it. On top of that, more frequently, the Macbook screen looks washed out (loss of colour depth). It doesnt flash and there are no blank/white areas of screen, just very poor colour depth. This can occur even coming out of screen saver mode. It seems to correct itself with time or disconnecting the dell monitor. Main programs I always leave open are Firefox +/- Transmission. Seems to happen regardless of programs being open or not. Have updated everything that Software Update can find to update. Anyone else having these problems or have any ideas how to fix?
if anyone else is having problems with their unibody Macbook pro screen getting washed out after a while - especially if the computer has been put into and woken from sleep. I run a 24 inch dell monitor along side my MBP in dual monitor mode, the MBP the slave monitor, with the Dell the main monitor. After a while of use, approx 2 hours, the macbook pro screen fades out/appears washed out. It seems to settle after either a restart or dimming the MBP screen to black for a few minutes. My MBP is not on a cooling stand but I'm going to get one Is this a heat thing, a firmware thing or a defective hardware? I'm running 10.5.6 and have updated the firmware/efi as per apple updates.
I have a 2 month old 13" MBP which I absolutely love. The only hitch is that there is an oddity when connected to my Dell 2008wfp display. It only happens when I wake the MBP from sleep. A number of things happen sometimes. Usuaully, when I wake the MBP from sleep, i get a black screen on both displays and all I can see and control is the cursor. Sometimes the main display will be black, but the MBP display will show the desktop wallpaper, but again, I can only see and control the mouse cursor. It should also be worth mentioning that the keyboard is rendered non-functional as well.
Sometimes, OS X will appear on both displays, with mouse cursor active, keyboard inactive, but I am unable to click anything or interact with anything OS X.
Anyway, I'm at the point where I need to mention this because it happens quite frequently and its getting rather annoying. The only way I can get out of this hang, is to cold reboot the machine. It happens everyday and at least 50% of the time I wake the MBP from sleep. When not connected to the display, I never get this occurrence. Also, this display worked perfectly when I used to own the classic 15" MBP, so its hard for me to pinpoint what exactly is the anomaly that is happening.
Anyone else experiencing this same issue? I am using a mini display port to DVI adapter to the Dell display.
I have a Dell 2408WFP on the way, as well as a Mac Pro 2.8 with the HD 2600XT, at long last!
The 2408 was recommended by several users of this site, so I wanted to see if you would be willing to share your calibration settings for the monitor?
I've read here about the important task of recalibrating this monitor and soaked up as much knowledge as a I could (as he does get into his settings a little bit).
Since it seems some of you would have a very similar system to me , I was hoping you could help take a little of the pain out of calibrating it (without an external device) and share all relevant settings with me (monitor settings, color profile, graphics card settings, etc.)
Is there really any big differences between these other than the number of inputs? Does anyone have an experience with these monitors, if so I would love to hear your input.
I usually use my 2209WA connected to my Desktop running Windows 7, but sometimes I'll connect it to my MBP. Windows seems to have found a color profile that works very well, which it got from Windows Update, created by Dell, presumably.It might not be good enough for someone who needs 100% accurate color, but it's good enough for me.
I tried two different profiles for this monitor connected to my MBP. The first was one I downloaded from a forum somewhere, and the second was the one Windows is using, copied over. The display looks OK with both, but the color depth isn't nearly as good as it is on Windows. Connected to my MBP, the colors look washed out and flat, while the same colors are much richer when the monitor is connected to my PC. For example, pure blue (#0000FF) looks faded when the monitor is on my MBP, and much deeper when it is on my PC. I tried changing the gamma setting under OS X (manual calibration), but it didn't have much effect. It is set at 2.2 for both 2209 profiles and for my MBP LCD's profile.
How can I make my monitor properly calibrated when it is hooked up to my Mac?
In both cases I am connecting the monitor with DVI (just moving the cable since I'm too cheap to buy a switch), and both OSes have it set at native resolution. The settings on the monitor (color, brightness, contrast, etc) do not change when I switch computers.
I just purchased a brand new macbook air this past week. I noticed within the first day of using that if my machine went into sleep mode, and I hit a key to take it out of sleep mode, it would go to a black screen with my cursor for about 30 seconds.
It does not do it every time but enough that it is annoying. I am coming from a mid 2011 mac air that did not have any issues. (only replaced for all day battery)
Do you think this a hardware or software issue? If i swap this mac out do you think I will just encounter the same thing?
I have read numerous posts regarding waking from sleep issues but they all seem to be affecting MacBooks purchased between 2012 and 2013.
I have a (reletively) new iMac purchased in Nov. 27" 3.06 Ghz 4 GB Ram. The machine sleeps on it's own overnight from non use and then when i get up in the morning I click the mouse and I hear the machine waking up, (harddirve, cd-rom, etc.) but the screen stays blank. This happens in OSX and Win7 doen't matter what OS is running so it appears to be a hardware issue. Maybe there is a firm ware update, or somthing. To use the machine at that point, my only option is to force the machine to shutdown and then reboot. If I reboot to fast, meaning if I don't wait about 5-10 seconds after the shutdown, then the machine proceeds to boot but without any visuals, the screen stays blank.
Should I just take the system back to the apple store? Will they grab the current image and put it on a new machine...
Is it possible to have the user account log in screen appear automatically when the computer is woken from sleep (regardless of who was logged in etc when it was put to sleep?).
I frequently get a blue screen of death after waking from sleep. I have to restart the computer to resolve the issue. This problem only began about a week ago, long after I updated to 10.7.4 on my iMac.
I'm not entirely sure how long my iMac has been doing this, maybe two weeks? When I try to wake it from sleep, the screen does not turn on. At all. At first I thought this was because my mouse and keyboard might not be functioning correctly, naturally the only remedy was to turn the computer off with the power button and to restart it (which took an abnormally long time). Today I remote connected with Back to my Mac screen sharing and it did not turn on either. I know it was awake because when I pressed the brightness buttons on the keyboard, it responded on my MBA's view of the screen. Normally, Back to my Mac does turn the screen back on. Anyone else have the same problem? It doesn't seem to matter WHEN it goes to sleep either. I've tried resetting the PRAM already and no dice.
When waking from "sleep" the screen appears normal but, the pointer leaves a trail of grey as it moves and the whole screen will turn grey if I keep moving the pointer. The computer is effectively dead. Have to shut down by using power off for six seconds and then re-starting. I know little about computers!
I recently reinstalled MAC OS X on my unibody MBP. I've installed all the updates and it's been working fine until now. When it goes to sleep automatically I press a key and it wakes up then the Airport icon in the bar at the top of the desktop stays greyed out. I have to go in and manually connect to my router each time the machine wakes from sleep.
Im using a MBP 13'' 09 I believe (9400M). Every time I boot into OS X 10.6.5 and now 10.6.6 my screen is all washed out. I can see stuff but there are just way too much "whites. "(With an external and also with the internal).
An easy remedy for the external just requires me to unplug and replug the monitor back in and the calibration automatically fixes it's self on how it used to be.
I just got my 11.6 mba yesterday. I absolutely loved it but after one day use and compared to my 13.3 mbp and my 21 imac , I found that the screen is very washed out, especially the red color. Does anyone else have this problem with their screen.

I've had my MacBook for around two months now, and I've noticed this problem ever since I got it. The screen looks sort of washed out, similar to issue the iPod touch had when it first came out. Blacks don't appear black enough. It looks fine if you're looking up at the screen, but if you look down to it, dark colors are too light. I've tried the color calibration, and it has helped a little, but the problem still exists. Is there a way I can get rid of this? I've posted some pics below. They were taken with my iMac's camera, so they aren't that good.
I just purchased a macbook pro 2.53 Ghz 13.3 inch laptop. I got it today and so far I'm loving it except for the fact that compared to my rev A macbook air, the screen looks a bit washed out? Like the screen and brightness on my MBA is still better?
Bought a Whitebook in August '08 and have noticed lately that the bottom of the screen (around the dock) is brighter than the rest. This extends to the top of the dock (which I have set at pretty small) but can be quite noticeable.
Has anyone heard of this or know any fixes? The screen has been calibrated but this isn't something that I could fix by re-calibrating.
i have had the same setup as before (external monitor, apple bluetooth keyboard, mouse) and up until yesterday its been waking up on its own. is there an option to stop usb from waking up the computer since i have my mouse connected?
I just occasionally have noticed my Blackbook, running 10.5.6, when I open it after closing it and moving elsewhere say, may have lost a lot of it's battery power. I think what's happening is it's not going to sleep properly (or it's waking up) when closed. This of course leaves me with not enough power (today 8% when I opened up). What concerns me much more is that the HD arm might not be in the parked position and damage could result with me travelling around. I have in fact had two complete HD failures in 2 1/2 years (though I have no reason to believe this is the cause, in fact I doubt it). I'm aware I can press the power button then select SLEEP and I often do when I'm just charging at home and want to keep the temp down (it's hot here!). Very interested to know what's going on though.....in fact interested in the bigger picture of HD arms when the things spinning as I use my Macbook outside and on my lap a lot, and can't help some movement of course. I emphasise when I shut the lid it normally sleeps as normal, this is just an occasional thing. So is it dangerous, what's causing it, and what about the bigger pic on HD arms when moving the laptop around?
My girlfriends Air has suddenly gotten a weird problem lately. Every now and then when she wakes it from sleep it seems to think that it has a second display connected to it. Even rebooting doesn't always solve the problem.
She has never used an external display with it before. The port looks clean (I thought there might be something there causing a short) and as far as we know there hasn't been any tinkering with any system files on her computer.
Anybody ever heard of this problem before? Or have any idea how to fix it?
I am not sure if this is related to the other wifi issues posted on this thread. I am hoping it is an easy Leopard configuration thing. But my wifi used to work perfect--until I patched my OS version. Now, whenever open the lid, it can never connect to my wifi router immediately like it used to do. It spends cycles hunting, and I end up having to manually go into network preferences and try a few times to connect, including rekeying the password.
I have a late 2008 macbook, and occasionally after going into sleep via closing the lid or according to the sleep timer, it doesn't really want to wake up. I open the lid/press spacebar and the computer sounds like it's waking up, the keyboard lights up, but the screen stays dark. I've tried waiting for up to 30 seconds before eventually I just hold the power button and hard reset. Upon restart, there is an error message stating that os x crashed. I haven't been able to let it sit for more than a minute or two, as it usually happens when I'm getting ready to give a presentation or something, fun right.

I have a 2.4 Penryn black MacBook. It's been waking up on it's own, overheating and shutting down since I installed 10.5.7. This happened when I first got it, and I took it to Apple. At that time, seems the RAM wasn't seated properly. It hasn't been a problem again until now. Yesterday, it did it twice. The RAM seems to be seated properly. Is there a firmware update or something I'm missing?
Everytime I put my Mbp to sleep it will wake up after 10 minutes on it's own all the time, I don't have low batteries on my magic mouse and keyboard, this never happened on my older Mbp. This is the new 2010 model. I have wake for network connection turned off. Anyone esle have this issue?
I'm using my Mac on an external monitor with a USB keyboard/mouse and the lid closed. When I put it to sleep using the remote, it switches off but then re-awakens about 5 seconds later. It's really annoying as it's usually when I'm in bed after watching a video and am too tired to get up and switch it off manually. How to make it sleep? Could it be the USB peripherals making it act this way? If so, how can I stop my Mac from waking on USB?
my air is rev B with SSD. when i open the lid to wake it up from the sleep, the mouse is freezing for couple of seconds and then back to normal.
it's not tthe whole OS freezing i believe, because ical event suddenly appears on the desktop when the mouse is freezing. so it's not the system i guess.
could it be the lack of voltage because of coolbook? but the system is so stable with these new lower voltages settings i applied a week ago.
When I wake my 13" MBP from sleep, the fan speed ramps up to about 2700 or so RPM even though the entire machine is cool. It eventually goes back to 2000 after a couple of minutes.
Sometimes when I let my MBP (see sig) go to sleep with the screen open, I come back and hit the spacebar to wake it up and it doesn't give me the password dialog box to wake it from sleep. All i see is a black screen with the mouse pointer on it. This sometimes happens when I wake and DO get the password box but if I wait and don't enter the password right away, the box disappears and wont come back. In both cases I'm forced to push the power button to shut it down and restart. Any solutions to this, or is it just a fluke?
Whenever I close my computer to put it to sleep and then open it up later, the computer freezes and I am unable to type in my password to unlock my computer and am forced to hold down the power button until it turns off and then reboot it. This has become a major pain and has only started today but has happened 3 times already. I have an Apple Bluetooth Keyboard and a Magic Mouse connected to my computer and am running 10.6.2 if that helps. I'd rather not have to shut down my computer all the time and I'm no longer covered by any protection.
