Apple monitor problem

Hi. I am from Romania and I have a Apple LCD display (m2454) with ADC conector. My video card provide DVI and VGA outputs and I reorder pins on ADC conector to use DVI output like in this page: http://developer.apple.com/documentation/Hardware/DeveloperNotes/Macintosh_CPUs-G5/PowerMacG5/3Input-Output/chapter_4_section12.html
With a power supply of 25V DC my monitor provide only 2 colors (when Blue and Green, when Blue and Red). The question is, the monitor is damage or I didn`t put some signal where it should be. Please help. Thanks

Possibilities:
Bad Monitor
Bad Video Card
Bad Driver
Another monitor would help in isolating the problem. If it displays the same anomaly, you would want to look at your video card. If not, the display probably needs repair. (You might also want to try reinstalling the latest driver for your card.) You don't mention how old your G5 is or what video card you have but the display, at least, is still under warranty.
You could also try resetting the computer (PRAM, PMU, etc.) as well as unplugging the display (both from the computer and power).

30" Apple Monitor as HD TV/DVD Source as Well?

Hi everyone! I am considering buying a 30" Apple monitor with my PowerMac and am considering the following:
Ditching my old TV and having just the computer and 30" in my bedroom. I want to use the 30" monitor for both my PowerMac and for watching DVDs, playing Xbox, and watching cable (both regular and HD). Is this possible? Will I need to sacrifice anything to accomplish this?
Thank you,
Keith

The Refresh Rate of apple's LCDs are a bit slow for good gaming. They give you a blurring effect with lots of movement. I wouldn't recommend it. Most LCD's right now are not great for gaming with the Xbox. Maybe I'm picky, but I got a bad headache and did not enjoy it. Also, you need to think of how you are going to get your dvd player/xbox connected to the LCD. It has a dual DVI input. You will have to run it through your computer with a TV-PCI card or a video capture card, if you have a desktop computer w/PCI slots. Also you will need a HD-Cable box with a DVI output. Even then you will have to keep unscrewing the cable to switch between your computer and the cable. Or you could find a TV card/video capture card to put the cable through your computer, but to be honest it may not look great on the LCD because the LCD has such a high resolution, and most TV, even the HD tv thats out now isn't truly the resolution of the LCD. You may end up not using the whole screen when playing games of viewing TV.
And then there is apple's pixel policy, as well as other lighting color problems, that they are not too willing to replace a 30" LCD with questionable problems.
For this kind of money, and for what you want to do. I would get a nice 20"LCD and a 30" Tube-Flat Glass screen HDTV from somewhere that offers extended warranties, and you will probably still save some money as opposed to the 30"LCD.And You will probably enjoy the DVD/Games/TV more. Unless you are editing HD video, or doing massive graphic design work/animation, I would bother getting such a large screen for your computer. It won't easily double as a TV/DVD/Game Monitor and it can't be coveredfor more then a year unless you buy it with a computer and buy applecare. And then you still will have to kick and scream at the genious bar to get it repaired.
Just my opinion on the matter. I went through this whole proccess previously.
Good Luck.

17" Apple Monitor ceased to display, how can I test it

My 17" Apple monitor suddenly ceased to display. I can't see what I'm doing! It has the two USB ports occupied by bluetooth and usb speakers both of which function ok. The power light behaves as normal. Is it possible that the actual display matrix can have gone? Is there any way that I can test or check it to assess what the problem is?
Any help would be great. Ta

Hello, and thanks for your responses. Its a 17" LCD screen.
When its connected the power light on the front is on permanently and does cycle through any sequence.. I'll try and check it again re the dimmed desktop when I reattach it again to test it out.
I guess I was wondering if it is possible to short out any circuits when attaching a USB 2 device to a USB 1 port as on the back of the monitor. I wouldn't have thought so but I'd be interested to know if anyone has any other input. This was the only change to my set up was when I attached my LaCie USB speakers to the usb port on the back of the monitor. They worked fine for a few days and then one day the screen wouldn't function.
Thanks for the link to the forum but it appears that the monitor I have is of the older variety of cinema display which uses the ADC rather than the newer models which may have a separate power supply. If I could check this monitor on another mac then I could maybe do a wee bit more analysis but due to the ADC connection then its not so easy to find another MAC of that vintage which has the ADC monitor connection on it. Also having to pay around £70 for and adaptor ( http://store.apple.com/uk/product/M8661B/B ) to allow me to connect it up to a powerbook to test it seems a bit much when the monitor may be worth nothing if it is completely dead.
I'll continue to try to resolve and understand this as I don't want to just dump the monitor if it is just a relatively minor issue to be resolved. Any thoughts are gratefully read.

Apple Monitor doubles as a space heater

Hi, Just got a 23" apple monitor and you could use it as a space heater. Had it on for about 2 hours and the thing gets hot, Real hot.... Is this normal.... Seems to work fine but it does get hot... Thanks Dave

These displays have no vents to let heat out. They are designed in such a way that the entire enclosure acts as a heat sink. So they do get hot. However, most users also find that the default brightness setting of "maximum" is way too bright. Lowering the brightness to about 75% will 'fix" the problem. The display will still be plenty bright and the case will still get warm but not hot.

Power Macintosh G3 (beige) Desktop Mac OS X Monitor problem

I am trying to use a Power Macintosh G3 desktop (beige) that has been unused for about 8 years now. When I first turned it on all was fine, but in subsequent boot ups the monitor has failed to come on. The green light on the monitor flashes. I can hear the operating system booting up but I can also hear a rather ugly sound - which I think has been described as like smashing glass. The happens once when I first boot up.
I would assume it is a problem with the monitor - but am not sure of this smashing glass sound and what that means. If I do have to replace or try a different monitor - are there issues in connecting etc - I presume I will have easy access only to a more recent monitor.
thanks

What kind of monitor are you using and how is it connected? Some older Apple monitors with the ADB pass-though (for plugging the keyboard and mouse to the monitor when the CPU is tucked under the desk) would not allow resolution changes unless the ABD connection was used.
The Beige G3 will always boot to 640x480 res and then change to your desired setting only after the users prefs load. That also means that, with a dead PRAM battery, it's going to reset to 640x480. If the monitor can't support this res, then you get black.
Try a PRAM reset. Find the "CUDA Reset button" using this logic board diagram:
http://macgurus.com/products/motherboards/mbppcg3mini.php
Press and hold it for 20-30 seconds to clear all the contents of RPRAM. New factory defaults will load into PRAM on the next boot. A weak/dying battery can lead to corrupted PRAM contents, and the CUDA reset is your new best friend for dealing with such nonsense.

30" HD Apple Monitor leaving ghost images and vertical lines

I have a Mac Pro Gen 1 with ati 5770 HD video card runing Snow Leopard. My 30" HD Apple Monitor will flicker and leave verticle lines and perstent ghost images from closed windows, even during shut down. Some times it will flicker back to normal, but then it will flicker back to leaving verticle lines and ghost images. I have tried using a different video card, same issue, nothing changes. I have tried instaling new video drivers and using old ones. I have been using the ati 5770 HD for months now without any issues. How do I fix this?

If two different cards produce the same results then I would think its your 30" display which is failing.
Update:
I just noticed in your sig you are using 10.6.8. There are some threads about video problems (flickering, not sure about vertical lines) with 10.6.8 (google "10.6.8 flickering site:discussions.apple.com"). So if you boot from your installer dvd which presumably has an older version of OSX (10.6.4 maybe?) do you still see the display problems?
Another thought - would an smc and pram reset affect anything? You might give it a try too.

Recomendation for dual Apple monitor?

Just swapped over to dual monitors today, but the Samsung syncmaster 22 inch P2250's produce too much heat. they make me sweat and remove O2 from my lungs when closer than an arm length away. Going to donate them today, but I would like to get a good graphics monitor or dual monitor setup.
any recommendations for an older apple monitor combo? have about 27" desk space. need to have the close up viewing mode for photoshop, video editing, graphic work type stuff.
never experienced such a bad problem with heat before from a monitor, is this a recent development in technology to make monitors unbearable to be in front of for any length of time, to maybe encourage more outdoor recreation?

found out that the old apple 20's didn't have as good a resolution as I thought.
can you use a good LED monitor, apples or elsewhere Like
http://eshop.macsales.com/item/ACER/B243HLBMDRZ/
and a smaller monitor and just use the smaller monitor for folders, email?
ideally, i'd like something the same height of the large monitor, but tall, not wide. like an ipad stuck to the side.
do dual monitors have to be the same resolution and orientation?

TS1367 I have a mac book pro, 2012 and an apple monitor but the monitor keeps going off. What is causing this? Why won't it stay connected?

Why won't my Apple monitor stay on with my mac book pro?

I know there were many more problems 5 yrs ago with 3rd party monitors and have been some issues in between also.
Apple does have what is needed to use multiple 30 inch displays and the 5770 is pretty mainstream and standard.
It is also about the only card being sold outside ebay and a couple places in case you want to take your chances with Nvidia 8800GT 1st gen model or ATI 4870.

Macbook pro crashes plugging into apple monitor

Hi I find I have a strange situation that whenever I plug my macbook pro into my apple monitor the screen goes blank and I have have to reboot the mac (or rather it crashes forcing a restart). This happens between 20% to 40% of the time.
Any ideas on what's causing this and what i can do?
I'm running Yosemite.

Just a quick note to add voice to this growing problem.
.Have reset PRAM, NVRAM and SMC but this does not seem to help
.About one time in four, computer will use battery as normal (when not plugged in to power) and have about 2 hours of 'normal' use
.Next time it is used, no battery power available > will turn itself off immediately after powering up. However, after plugging in to power, battery will indicate 97% full
I have had the MacBook Pro since May and have put up with the whinning, had the battery replaced in early September under the replacement scheme.
My own theory is that this problem has only just occured (within the last two days) but is an ongoing problem with 'power' issues and the MBP. Other problems relating to power management?
1) Computer would not always go to sleep when the lid was closed. I would open laptop bag to find a very hot Mac inside
2) Random 'freezes' of the Mac when it would not respond to anything despite being woken up from sleep mode
3) Very bad battery life
I think that, while Apple have been aware of this problem, they have probably rushed their firmware update to try and solve the problem and brush it under the carpet to stop another fiasco like the battery recall.
I cannot get to a genius bar until the middle of next week so cannot comment on the official view of apple on this problem.

External monitor with MBP. Non Apple monitor

Am about to purchase a new MBP and I believe I will be able to get a new Dell 24" monitor.
question, I have read that many monitors periodically require Firmware upgrade to work at their best.
For instance, there is a new update for the line of Dell monitors in which I am interested,. However, the firmware update (software) is only available in a ".exe" version which is Windows software,.
How do Mac folks upgrade their non -Apple monitors? I know plenty of y'all use third party monitors.
any tips on installing/using a third party monitor with MacBookPro will be will be appreciated, as well.

your reply is very reassuring- I am going to purchase an external monitor for both my new MBPro and the current Macbook which I own.
Lots of posts here assure me that using third party monitors can be done without too much hassled. (I just can't afford the Apple monitors otherwise would purchase)
My concern came from stuff I have read (CNET) and In Dell forums where Dell concedes that the line of monitors I am considering DO have some difficulty with "banding" (Dell was getting numerous troubleshooting calls and exchanging monitors).Apparently the new Firmware, just published, fixes the problem.
I guess I can run the firmware once I have Windows running (Parallels) in my new MacBookPro. And maybe companies will start releasing their software in Mac-usable format now that so many more Macs (especially laptops) are being sold.
Thank

Mac Pro Dual Monitor Problem

I have a MacPro 4,1 with an ATI Radeon HD 5770 video card. I'm running OS X 10.6.8. I have an Apple 20" Monitor and a Hannspree 23" monitor. The problem I have is that when the computer goes into standby mode, 2 times out of 5 it will come back up with the primary monitor switched from the Apple to the Hannspree. I then have to go into the Display Preferences and switch the monitor arrangement, and the menu bar. Not a huge problem I grant you, but one that is vexing me nonetheless.
Also on an occasion...perhaps 1 time out of 25 the Apple monitor has a case of the jaggies, and is only fixable by shutting down the whole computer and restarting. This is really bad, considering it reminds me of when I get migrane headaches and my vision is constricted. It almost makes me nautious.

Apple's has three, 2xMDP + DVI

Is there an Apple Monitor that is Macbook and PC compatible? Perhaps with an adapter?

What model is your apple airport? A1xxx from the base please.
Is the computer running Mavericks as per your profile?
Time Machine has logs you can access.
This might give you some idea of what is wrong.. but I have to say if you run Yosemite.. therein lies your problem.

M93p dual monitor problems; monitor turns off and cannot be turned on again

Hi,
we have multiple M93p tiny computers causing problems in dual monitor setup (VGA / Displayport->DVI). Our users (already >5) keep telling us, they leave their workplace, return, then DVI attached monitor if off and they do not find a way to turn it on. This is true; the only workaround that has been found by our users is to bring Win7/32bit into standby mode and awaking it again.
Needless to say, we turned all windows energy saving options off (computer standby/hibernate, monitor turn off). Still the problem appears.
Maybe there is something wrong with DVI power/DVI signal?
- Monitor independent, as far as I can see
- Independent from Windows energy saving modes
- BIOS updates did not help
[todo]: Try Intel/(AMD?) drivers, let users test.
I haven't seen exactly when the monitor turns off because it is reported by users. I had a testing machine, but was not able to reproduce.
http://forums.lenovo.com/t5/A-M-and-Edge-Series-ThinkCentre/Dual-monitors-problem-VGA-and-Displaypor... is related.
Anyone?
Thx

Make a "Genius" appointment at an Apple Store to have the machine tested.

I'm trying to connect my 30" Cinema Display to my new Mac Pro along with a new Apple 23'" monitor. The new Apple monitor is fine. On the cinema monitor everything is blown up pretty large. Any ideas on how to solve this?

Possibly mundane Mini-DVI to VGA into an external monitor problem

Hi,
I've had a look over the interwebs regarding my problem and it seems as if it's not unusual to have external monitor problems but I'm not sure if mine is slightly different:
I had a perfectly working set up with my new Macbook (the white one, '06 model I believe), that was connected to my Hanns-G HU196D monitor via a mini-DVI to VGA adapter, no problems whatsoever. But for a couple of weeks now my Macbook just flickers a light blue colour, with nothing at all on the monitor, and my macbook is unusable until I remove the adapter. I've read about updating firmware but I can't see my desktop once the macbook is connected to the monitor so it's not possible to configure anything. I've read somewhere that my external monitor isn't compatible with this set up, but it was until a couple of weeks ago!
My Macbook's 4 months old now and since then I've bought a new mini-dvi to vga adapter and a new VGA cable, no connections seem loose on either mini-dvi port or my monitor's vga port.
Thanks if you can help!
Jack

You will need to use a mini Dvi-dvi and a dvi-svideo/rca adapter.
Joy joy hallelujah.
Pardon the sarcasm...I just wasted 3 hours of my life trying to sort the issue out.
Heard a KWORLD PlusTV PCTOTV Converter SA235 USB 2.0 Interface would sort the issue out for under 40$ but it's not Mac.
Hope that helps.
