I just bought a Dell U2410 to use as an external monitor (connected with DVI) with my MBP. After initial problems getting the best calibration setup I'm now very happy with it except for one annoyance. The problem: When the MBP puts its display to sleep the Dell monitor goes into sleep mode and then immediately wakes up and then goes back into sleep mode, cycling like this indefinitely.
View 3 RepliesHave a brand new MBP 13" using Thunderbolt-DVI adapter with my old Dell 2405 LCD. Have an interesting scenario ... when the display goes to "sleep" there is still some type of signal coming out of the display port. The monitor will stay on and just blink "NO SIGNAL DETECTED ON INPUT 2". But the monitor actually still stays on.When I put the entire laptop to sleep them the monitor will properly power down to sleep mode.Â
I don't think its the monitor because I've used this monitor with a number of different machines and graphics cards, in every scenario when I had the display set to sleep it powered off just fine. Â
I have a 2.5Gh intel core i5. I put it to sleep last night and today when I went to turn it on it wouldn't wake up. It wouldn't respond to pushing the power button. I unplugged it and plugged it into another power outlet (both worked with other appliances). finally after about about 20 minutes I unplugged the power cord from the back of the computer. As soon as I pushed it back on the computer started booting up (without even hitting the power button). What happened? Did my power drop and this was sort of a reset for the mac?

I picked up a new MacBook yesterday and I noticed a weird issue when coming out of "monitor sleep" mode, not regular sleep mode.
When I move the mouse, the external monitor shows what you see in the picture, kinda like a TV with no signal. The MacBook screen works fine so what I just do is unplug and re-plug in the DVI plug and everything is good again.
My 24 inch Dell monitor worked fine with my M1330 and other computers so I know it's not that. Does anyone have the same issue or maybe give me some light on this?
I recently got the Dell U2410 and I felt like out of the box the color and everything was way off, and certainly no where near matching how things looked on my MBP screen. I went through the little calibration process in the system preferences (with the advanced options) and it's somewhat better (I don't think the gamma was at 2.2 before), but it still doesn't seem so great. The brights look kind of blown out, the shadows are a bit too black, and some of the colors look off. Also, if I look at a solid color I can see moving lines (almost like a much more mild version of when you record a computer screen with a camera running at a different refresh rate).
Did I get a crappy one, or do I need to do something different? I had heard so many good things about this monitor and now I'm considering returning it for a 24" ACD.
I have a second monitor (Dell 20 inch widescreen) hooked up to my 24 inch iMac, and while I'm running windows, when the iMac monitor sleeps, it sleeps. But, in Leopard (v10.5.7) whenever the iMac monitor sleeps, the secondary monitor does what a monitor usually does when the video cable is unplugged (does the whole factory test thing with the box of red/green/blue randomly moving around.) Is there any way to make it sleep?

I go to shut it down from the apple menu, it attempts to go through all the stages needed for a shut down, the screen goes black like normal, and then it restarts again (so, while, it nearly gets to the end of shut down, it never quite makes it, and starts up again!) The same thing happens when I decide to restart - there is no pause between shutting down and restarting, indicating that it does nor restart at all.
It does not sleep either. I put the lid down and everything is still going inside the laptop!
I hope that's a good enough explanation of what's happening!
The only way I can shut the computer down is by pressing the power button in the top right hand corner of my macbook - forcing a shut down.
I've tried resetting the PRAM and repairing disk utility but it has done absolutely nothing.
My MacBook's sleep light does not function unless I place a death-grip on the top case right above the light itself. What should I do to repair this light properly? Any articles I should know about?
View 2 Replies View RelatedRecently I installed the Snow Leopard OS on my Macbook Pro, previously I had 10.5 installed. However, now when I connect my Macbook to my flatscreen TV (Panasonic Plasma), using a mini display port cable to an HDMI cable, there's a black border around the edges of the picture. Before the Snow Leopard upgrade I was able to view the entire screen area of the Plasma TV, without any borders. The only thing I've done differently since then is install Snow Leopard. Does anyone know how I can fill the screen with image without using the zoom option on the TV screen, as the zoom cuts off some image at the top and bottom?
View 3 Replies View RelatedIf I connect a external monitor and keyboard to my late 2011 Macbook Pro (running Lion) it starts up just fine. But if I try to start it up without these (or any other devices) attached, I get no display on the internal screen and the internal keyboard is ignored (the caps lock light doesn't light up when the key is pressed). However, I don't think it's a hardware issue, as a PRAM reset seems to work (I get the second chime) indicating that the keyboard is OK. And I get a second or so of grey screen before the screen goes black. I've tried resetting my SMC and my PRAM. The latter seemed to fix the problem once - but then it came back, and won't go away again this time. I've also tried starting in safe, single user, and verbose mode, but none of these seem to make any difference. I've been having some issues installing Windows (under both BootCamp and Parallels) but wouldn't have thought that these were related.

I have a 30 month old MacBook Pro (the SantaRosa line from June 2007)... And was still using the original battery up until 3 days ago. Its capacity suddenly dropped from 83% down to 45%, so I took it to an Apple store, they did a diagnostic, and without question told me the battery was defective, and just gave me a brand new battery with only 1 loadcycle on it. So today I decided to calibrate it, had it charged up, unpulgged it and let it run until it was 'supposed' to go to sleep... It had 0% left on it, the screen shut off, and the sleep light was just starting to dim, when I heard the hard drive go . (As if one pushed and held the power button, aka hard shutdown).
It seems it didn't have enough reserve capacity to let it go to sleep, so instead of waiting the 5 hours (as it wasn't sleeping, and pressing the button on the battery showed no lights at all), I decided to plug it in right away. Would it be a good idea to calibrate again, or simply wait a month or so and do it again then?
When I turned the computer back on, it didn't even resume at my desktop, so not only did it not get to sleep properly, it didn't even have a chance to write the memory to the hard drive, and now the actual battery capacity in Coconut battery is showing up 95%, 5253mAh
Just curious, as 30 months ago when I first got my original one, it calibrated properly and didn't completely die when it got to reserve capacity...
During start up I get the apple logo and everything boots although it takes forever, the apple logo goes away screen goes blue, and sometimes it loads to the login screen about 10 mins later, and sometimes it just sits there. - During restart, it shuts down makes all the appropriate sounds, screen goes dark, and all you hear is a residual humming from the inside under the keyboard, and then never restarts. (You have to force shutdown) - Same story as above with both shutdown, and sleep.
The only way to get it to load successfully is in safe mode, but even then it still wont do the above problem correctly, it just at least starts.
- Resetting the PRAM, Holding power button for 5 seconds until repeating flashes, I've tried reinstalling snow leopard 5 times, I've checked for updates, I've repaired disk permissions, I've repaired the disk, I've even tried stepping the OSX back down to 10.3(The original operating software for this MB)
Just this morning, I opened my MacBook which had been sleeping overnight. for some strange reason, even when the screen was up, the light at the button was still glowing (indicating it was asleep). I tried forcing it to shutdown. When I turned it on again, it went to sleep mode right when the desktop was about to load. I tried booting from Windows 7 but sure enough, when I reached the login screen, the computer went to sleep. I concluded that it was definitely a sleep sensor problem.

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 used to have a mac Mini that connected so effortlessly to the monitor and allowed the full resolution (1920x1080). But I'm trying to do that with my MacBook (as I recently sold my Mini) and I'm unable to get it to do what I want to. I have Snow Leopard. It would not allow me to do anything until I updated the OS. The monitor was not recognized at all. Except I noticed when I plugged it in, the macbook screen would flash...so I figure it's recognizing something. But in display settings, detect display wouldn't show anything, neither would restarting. That is, until I updated Snow Leopard.... Anyone know why this might be? And now that I've been able to get something on the display, I'm still not at all satisfied. The resolution is terrible. It will not allow me to choose anything other than the resolution on my macbook screen, but over 23" it just looks terrible. Not only that, but the Macbook screen stays on. I want the mb screen to go off, and full resolution be on the external monitor. I can choose another option for an extended desktop but that's just ridiculous. I have no desire for anything like that.

View 3 Replies View RelatedMaybe this is a dumb question, but it seems on my system if the screensaver runs then the monitor sleeps, the screensaver is still running when i go to wake the monitor. does that mean its been running the whole time wasting cpu cycles and drawing more power than is necessary? you'd think it would stop.

In the Energy Saver settings, the monitor and computer are both set to go to sleep at 15 and 20 minutes, respectively, and the monitor goes to sleep just fine. The computer never does, as indicated by the solid white indicator light on the front of the MBP and the fact that it stays warm after not being used for hours.

I am running an adaptor to my G5 from the ADC monitor (DVI to ADC).The screen usually runs fine when I reset the monitor or turn it off but as for when I put it to sleep, no such luck..This has happened once before and last time I just waited and randomly turned it on a couple days later and boom, the screen booted up.I have tried basic options, like resetting the computer several times, pulling the power cable out of the G5 for several minutes and even a PRAM reset but nothing seems to have made it work as of yet.I assume it's within the G5 as it has happened a few times and the monitor works fine when I test it on other computers..Also as I mentioned before this is not the first time it occured and it just randomly seems to come on whenever.

I was wondering if there was anyway that I could get my Dell E173FP monitor to sleep when I close the lid to my macbook pro. I do not have it on mirroring mode. When I close the lid to my laptop it will just switch my desktop to the monitor instead of the monitor going to sleep with my macbook. When I press the power button and click sleep or go to the apple menu and click sleep it will work though. This really irritates me and I would like It to sleep when I close the lid instead of having to do more.

Here's a weird problem I just got on a new (refurb) MBP.
Sometimes (not always) when I comeback to my MacBook after it's gone to screensaver then display sleep (though not full system sleep) the cursor is invisible upon wake.
I know the cursor is still there, but it just can't be seen on screen. If I go down to one of my hot corners, the associated action still happens (in my case sleep the display / activate screensaver -how ironic ), and if I roll over the dock I can bring it up and magnify the icons as I roll over them.... all with no visible cursor whatsoever.
In fact, I only get a cursor once I click on an app and either launch it or bring it up from being minimized / hidden.
This has never happened on any machine I've had before, but by all indications it's a software problem, nothing to do with the hardware.
It's a new 15" MBP 2.2 Ghz, 4GB Ram running Leopard 10.5.2 with all updates (even the recent keyboard update).
A search on this brought up someone else on another board with the same problem, but then the issue got clouded with discussion of dual-monitors or external displays (neither of which I use).
I'm going to go fix permissions right now, but I was hoping somebody here could ID this and help me figure it out.

I'm using a Mac Mini (running 10.3.8) connected to an old View Sonic E95 monitor. No problems except that every time I leave the computer for a while it goes to sleep and "forgets" what display it is connected to. When I hit a key or whatever to reawaken it, the display resolution has been re-set to "VGA 800x600" and I have to tell it to "Detect Display" again..
Any clues? I have looked on the forums and Google with no success .
