Desktops :: Monitors Won't Turn On Sometimes Since Upgrading To 10.6
Nov 21, 2009
Occasionally after a full shut down, when I restart, only one of my two monitors will start up.
It sometimes takes half a dozen restarts before it finally comes on. There doesn't seem to be any reason for it, or lose connections etc.. and it doesn't happen during a normal restart.
The only time it happens is if I have to do a full shut down or if the power has gone off etc.
I hit the power button to restart the computer, I hear the startup chime and after a very long wait, only the left monitor will start up. The right one acts as if it's never received a signal from the computer to activate. The power is on and it's ready to go but it takes at least 6 to 12 more startups from scratch using the main power button to get it working again. Sometimes, neither monitor with turn on.
I have read over and over how many users have sleeping issue problems. The way I look at it is just leave your computer on. Mine runs 24 hrs. a day 365 days a year. I never put it to sleep. Yes you well save a little hydro but your problems will go away. When I am not sitting at the computer I turn off the monitor. I have done this for the last 10 years on the PC and since Feb.14 on my new MacPro without any issues. So in my opinion, leave your Macs on and turn off your monitors when not in use.
Current status is...Cannot turn on, screen is dark. Blue light on power button stays on. Can't restart after holding it down...Red light inside box is on. Read that it might be air deflector trouble, but that's not it. Opened box removed plastic and returned it...another red light lit , then turned off. 1st red light stays on.
Before the above began, a restart would end up in a hang at the end of the progress bar. Ran Disk Util from Install CD which showed errors: "Volume Chk failed...HFS Volume needs repair". Ran FSCK whick said it fixed all. Ran Disk Warrior afterward b/c still would hang at startup. Says all now OK...but NOT! Have tried saving files thru Disk Warrior...but now, as per above, cannot get it to start up. Or turn off...
Would like to get it lit to save any additional files if drive is near the end...

The current setup already uses about 395W and this will increase with more monitors and video cards. Is there a way to turn off all but one (or two) ACD monitors (and the unused video cards) when not required? The latest Display page in OS-X 10.5.7 System Preferences has removed the option to turn off a monitor (and not the Mac Pro itself) via the side button. Tried turning off the power supply, but this is bad for the monitors, is impractical No rear-monitor USB2 or Firewire400 ports are used (for now).
Just got my new 2.8 with 5870. From the start it gave me some trouble getting it to turn on. I kept trying different plugs and such throughout the house and randomly I got it on. It was working good but I noticed that waking it from sleep the machine will click and the sleep light goes out and a red led behind the grill comes on briefly. I try pushing the power button to hear another click and the red led flashes. These problems seem intermittent and sometimes it will sleep fine. Im using 2 acer monitors connected via 2 vga-mini display adaptors.
Had (used) iBook G4 several months now & thoroughly enjoy it, even tho' I live in the sticks where there's no hi-speed/wireless available; I connect to internet & power, which is fine.
This weekend I went to turn off my iBook & it wouldn't turn off. It's now permanently on, with opening info barely visible (like I need to click on F2 to brighten up, except nothing happens).
Currently using my "back up" computer, my iMac Grape, which is pretty much an antique by now.
But I can turn it off, if I choose "Share my internet connection for other units". (I don't know, if this is the right text in english, because my OSX is in german)
2) Now Bluetooth is OFF:
But I can't turn it on, because the checkbox "ON" is inactive.
It turns only on, if I choose "New Unit"(?). Then there is a new window, that says, that this is only possible if Bluetooth turns on. If I say OK, bluetooth turns ON.
Back to 1)
What's the problem. Why is this f* checkbox for turning bluetooth on and off inactive?
This is not a hardware problem, because I can have stable bluetooth connections.
I did a smc and am pram reset. But it doesn't help.
I was playing around with my mac g4 logic board... ( yes, i know... ) anyways, i press the power, the light turns on, and the fan spinns up then everything just turns off... http://docs.info.apple.com/article.html?artnum=95035 ^ my tower, (agp graphics, ftw)
I'm just wondering what the cheapest way to go about this is. Currently my graphics card is the 8800, but I think I've read that you don't have to have the same graphics card to add more monitors (the ATI base graphics card will do just fine). So do I just need to purchase one from apple or am I able to get one cheaper from anywhere else? Also all of the supported graphics cards output 1920X1080 right? And on a side not - this output will be going to my television - is there any way to make front row default to the television output?
couldn't find an answer so far: Is it possible to run 2x 8800GT (Apple or flashed PC) in one Mac Pro 2008? I know, SLI doesn't work but I am curious if I can run 2 monitors (e.g. for FSX in Bootcamp). Did anyone try this or is this outside the Power-limits of the PCI bus?
Every couple of days, after my screensaver has been running for a few minutes... both of my monitors will shut off. Then no matter what I do, they won't turn back on again. The only way to get them working again is to do a forced restart.
1. MAC OS X iAtkos 10.5.7 updated to the latest version. 2. GygaByte GA-EP43-DS3L 3. nVidia GeForce 8500 GT 256 Mb 4. Nec AccuSync LCD 223WM (LCD 23 ") 5. LaCie Electron 22 Blue IV (CRT 22 ")
Problem: When connected to two monitors, one of them displays a welcome screen, and then both turned off.
I am trying to make a video wall of 4 - 6 lcd panels, all displaying different lo-fi videos. Ideally I would like to have one computer driving all of the panels. But I don't know what hardware / software i need to connect more than 2 monitors.
I recently purchased a HP 2009m glossy 20" monitor. I have a late 2008 model macbook pro (glossy). I have been having a hard time getting the colors and whites to look exactly the same. I have tried calibrating the display over and over but the whites never look exactly the same even though the default white points are the same for both the macbook pro/hp displays. Any hints outside of getting a sensor/external program?
I use my MBP 09 unibody closed and attached to a large monitor 90% of the time. I'm finally changing up my entire setup because the HD TV screen I have been using to do work is hurting my eyes. I'm tryin to have a baller setup but it seems unlikely this is possible...
If I buy 2 LCD monitors (two LED apples are too expensive for me right now), can I get them both rigged up to my closed MBP, mirrored but at the same time duel separate function display? There must be some kind of adapter that allows you to run that.
Ideally I would have my left over HDTV on another desk to the left of the duel monitors as a 3rd one that I could use as a preview monitor for video and design. and/or just use it as a 3rd desktop space where I could say, show a client or friend a sample of finished work full screen, or put on a movie or run Itunes visualizer and music, all while I am using the main duel LCD computer displays to do work.
setup: i have a dual 2.26 GHz quad core xeon mac pro with 2 nvidia geforce GT120 graphic cards. i need to connect 2 displays dell 2407 wfp and one LG TV as a third monitor (which also is connected as a video monitor via a blackmagic intensity pro). question: on which port (DVI, mini display) of which graphics card (lower, upper slot) should i connect my 3 displays?
I recently acquired a used G5. When I look at "about this mac", it tells me that I have a two processor, 2ghz machine but when I open the case I only see one G5 icon. The serial number is from late 2005. I just wanted to make sure that I have two processors as I'm planning on selling/trading up to a mac pro.
I have a fairly new Mac about 1.5 years old. Recently I am having an issue with it shutting down periodicly for no apparent reason and then it starts back up> I have noticed it does do this by bumping the desk or hitting the screen but it is only every so often and can't duplicate it by trying these things.
I know you can get the DVI external dongle but I am wondering if you could hook up two external monitors to the MBA. If anyone has tried this please post with pictures or video.
Trying to pick internal HD's for a new Mac Pro. Do the SATA 600's give me anything over the SATA 300's. Probably going to set-up an internal software RAID of two or three, till I can afford a decent external RAID. Does the internal data transfer speed max out at some level that buying a SATA 600 drive would be a waste? Also, I have two existing 20" Apple LCD Monitors, probably 5 years old that i need to use. Is the appropriate adapter simply the MDP to DVI connector? They're currently connected to a G5.
I'm curious if anyone has tried out Spaces with Dual Monitors yet?I'm not sure if it will matter or not, would kind of be cool to be able to specify which space goes to which monitor.....I have a New iMac with extra 20" LCD and will be upgrading to Leopard tonight, so I guess I'll know then...just wondering what to expect.
