IMac to an LCD TV, Ahhhhhhh!!

Hi
Sorry if you've read this but i posted it in the wrong forum earlier.
I have plugged in my iMac to an LCD TV using mini DVI to HDMI. Now is it possible to turn the iMac screen off and just leave the HDTV screen on?
If not this would be a great feature to have in 10.5 as increasing numbers of people have the macs in the longe, and it very annoying having the imac screen on whilst watching movies on the 32" lcd.
many thanks, Ben

I don't believe there is a way. You can always cover the monitor with a towel or something similar. I have a cover made especially for my iMac from acmemade.

My imac G4 Display LCD slowly moved to down always...

Hi! I have imac G4 17 LCD model but the LCD screen can't stay still and it always moved to down slowly. I try to find some screws but no luck. anyone know how can tighten the screen? cheers

Hello and Welcome to Apple Discussions.
Have a read of this thread. There are tools out there called Neck Tool and Neck Tool Pro but nowhere I've checked longer stocked them. If you can find them it will avoid a trip to your local Apple Authorised Service Provider.

Imac g5 to lcd tv

I have a imac G5 17" flat panel and a samsung lcd 26" tv with 1xhdmi, 1xscart, 1x s-video and rca audio connections, what i dont understand is how to connect the two. Iv'e heard that s-video sacrifies on quality but is the chaepest option. Please help.

Scart :
is likely for Satelite tv boxes + High end video machines but is old tech and can not connect to your Imac without you spending some money buying a device to connect it to and then to your Samsung.
HDMI:
is only recently released and if you do not have the latest ATI graphics card then likely not worth the use.
S-video / RCA :
S-video is better than RCA but this mostly depends on your other devices that connects to your Samsung.
S-video is the improved RCA and depending on your cables / quality of your cables it will come close to HDMI.
I just use the S-video cable that comes with my Pbook.
You should likely have in the box that shipped with your Imac have a "something to rca" or "something to S-video" cable that fits in the small graphics out connecter on your Imac or you can get one for $20-30 online.
PS: get some Monster Cables or 99%+ silver/gold/oxygen free or better cables if you are serious about sound + video quality but you have to have very good eye's and extremely good ears to make it worth your while.
Hope this helps.

Late 2009 imac with dead LCD; external monitor?

Hello, all
I need some help. The LCD on my late 2009 iMac has failed. I took it into the Apple Store and they told me it was dead and it would be $500+ to replace it, which I do not have.
The machine is intact, however, other than that! The Apple Store rep even told me that they tried it with an external monitor, to validate that the video card is working, and it worked fine. Great news!
My question, however, is how do I get it to boot to an external monitor?
I have booted the mac in target disk mode, booted from that target disk on another mac, and changed the settings so that the display is mirrored onto a second monitor. When I boot into the iMac, however, I get the Apple Logo and the "white screen of death" and the machine never finishes loading using the external monitor. I need to know if there is some way to force it to use that monitor for the primary display.
Cheers all, and thanks for any help!

Hello,
I'm wondering if boting from it's drive on the oother Mac didn't write some of the other Mac's Monitor info to it?
Instead of Mirroring, what if you make the external monitor the main one by dragging the Dock to it?
If you can ever get it to boot, this thread may be helpful if you want mirroing...

Imac late 2013 lcd screens compatibility

Hello everybody. I have an imac 21.5 inch late 2013. The exact model is EMC No 2638. It accidentally fell down and the lcd screen is very damaged. I want to replace it. The model of screen is LM215WF3 (SD) (D2).
I want to buy this part but I found this model: LM215WF3 (SD) (D1).
Can anybody tell me if it is going to work with mine?
Another question. What are the models that can work with my mac?

Hi gajonormal,
Thanks for visiting Apple Support Communities.
If you have not already, I recommend calibrating your iMac display:
Adjust your display to show accurate color using Display Calibrator Assistant. The colors on your display can be altered by many factors, such as ambient light, the position and angle of the display, and the age of the display. Calibrate your display regularly to ensure accurate color.
Choose Apple menu > System Preferences, click Displays, then click Color.
Click Calibrate. Display Calibrator Assistant walks you through calibrating your display and then creates a calibrated color profile.For a more detailed calibration of your display, select the Expert Mode checkbox, which is at the bottom of the introductory text.
Some displays have additional built-in color accuracy and calibration features. For more information, see the documentation that came with your display.

Ups for imac g5 20in lcd

TIA for any help re: my quest for a ups. i believe the imac g5 -20 in. is 185 watts. to determine the VAC of a proposed ups, one must convert the computer watts to VAC. i understand that the wattage is 60 - 70% of peak power and that figure ( peak wattage) is the desired VAC. therefore, i would need a unit of about 300 VAC. this seems to be a very low number as most of the units i see at the store are for 800, 900 or 1000VAC.
also, i understand that the ideal situation is to have instantaneous switchover in the event of a power loss, however, those units seem to start at $400 plus.
my only desire is to shut the system down properly to avoid damage to hard drives etc. again, TIA

Hi Brenmar and welcome to the discussions!
The units that you see in the store are larger than what just your computer would need. Remember, a lot of people are still using CRTs - shudder to think! - that use a lot more power than LCDs. A UPS is also designed to power more than just your PC also. People have printers and routers and such plugged in there as well, even though you are not really supposed to plug in a printer.
If you use the APC configurator and plug in you system info, it will make several suggestions. I put in a G5 iMac with the 20" display, and inkjet printer, a cable modem and router, and my powered speakers. It suggested an 800VA unit which sounds a little high. I have a 650VA and it works fine.
I suggest APC very highly. I need to get another UPS for my other PC and will be getting an APC brand this time. It will connect by USB cable to your Mac and be detected under your energy saver preferences.

Early 2009 24" iMac Haywire Display: LCD Panel or Logic Board?

Hi,
My 24" display just developed severe vertical and horzontal lines, mouse trailing, color changing and flickering. The problem begins as soon as the computer is turned on (even the Apple screen goes nuts).
When I plug in an external display, the external looks just fine.
This is one of the Nvidia GeForce 9400 chipsets, so there is no separate videocard board to replace - it is integrated onto the logic board.
It seems like it should be the display panel because the external monitor works fine, but these are complicated machines.
This is an iMac 9,1 Early 2009, Core2 2.66 Mhz machine.
Thank you,
Josh

Can you connect an external monitor and test? If the artifacts do not show on the external monitor, some component of the display is faulty but not the logic board. The dispay repair is not cheap but cheaper than replacing an LB
If the same artifacts show on both, well... it's the logic board.
AHT seldom picks up display faults.

14" imac 1.83GHz LCD screen suddenly too bright

My computer screen is suddenly too bright with a sort of a white washed look. I've checked the display settings and brightness in System Preferences and played with the greyscale and white on black options in the Universal Access panel, all to no avail.
I hooked up an LCD projector and the projected image is perfectly normal while the computer display is impossible to read. Even the most dim setting is too bright. Help!

IMac 20-inch LCD

Hi
My computer has been off for a week and i decided to turn it on and to my shock and horror, found cracks in my LCD screen turning half of the pixels black.
I HAVE NO IDEA HOW THIS COULD POSSIBLY HAVE HAPPENED.
My warranty finished 1 month ago! WHat bad luck!!!
Just need to know what is the easiest way to get a replacement screen and if there are any cheaper options. Thank you so much!

seeing that you are from the land down under, ebay would be your best bet for the lowest price, but 20" LCD's are hard to find that are known working. your best bet would be to find a G5 that does not work and pray that the monitor does. I have been looking for over a month now and only found one 20" LCD which has a small dark spot in it. It is from a G5 (which I assume you have) and I have a G4. If I can ever find another 20" LCD I could contact you and sell you the one I have now for what I paid for it on ebay plus shipping to ausie (I paid $88US for it). I do have my old perfect working 20" from my G4 but I ripped a small ribon cable out of the LCD glass and not it is too hard to fix

IMac 20" A1224 (EMC 2133) LCD bright grey but no video

Hi All,
I have an iMac 20" A1224 (EMC 2133) LCD boots up bright grey but no video, not even the able logo or spinning gear. After waiting the normal amount of time, the machine responds to keyboard input, i.e., I can change screen brightness and get the machine to beep at me by hitting various keys. I attach the external monitor and it works perfectly.. shows the desktop background after the computer boots up. I even booted the machine up to Ubuntu 11.04 GNU/Linux and was able to surf the Internet while looking at the externally attached display. All the while, the iMac LCD stays bright grey. The only time I see even so much as a flicker is when the computer boots up to GNU/Linux, where it flickers quickly once but then returns to bright grey.
I've checked all the connections, I've run the command+option+p+r, I've unplugged the machine for over 12 hours and held the power button in and turned on power (to reset SMU), and I've disconnected the hard drive (shows a blinking folder if I have the external monitor attached and boot with the LVDS cable detached). I've even checked the LED lights - all four are lit.
Very Frustrating!
So now I'm left with trying to swap out parts.. An expensive idea to say the least!
$24 Apple 922-8167 Cable, LVDS
$250 ATI Radeon GPU
$190 Apple iMac Intel 20" LCD Screen M201EW02 v.B
Does anyone know a way that I can test to make sure which part to replace?
Thanks!

Oh and for those who might end up in this same situation... I was able to get the externally attached monitor to be the main screen by first unplugging the LVDS connection (from the LCD display to the motherboard), then booting with the external monitor on and attached. This is nice because now I'm able to use the computer as normal (while viewing it in the external monitor), and I can run a time machine backup. I tried mirroring displays, gathering windows, changing the resolution and brightness and nothing has yet brought back the video on the LCD panel.
I still wish there was some type of testing software to check the GPU and tell me it's working perfectly... because then I could purchase the replacement LVDS cable / replacement LCD with confidence that replacing those items would fix the problem. Apple should attach these LCD panels with a DVI or HDMI connection internally... this way one could always (and easily) attach a monitor to the main output port and be able to easily isolate whether a video problem exists with the LCD/cable, or the GPU/Logic Board.
Also, what's up with the replacement ATI GPU being $250+? That's ridiculous because I can buy a decent 3d-gaming capable PCI-X 3d graphics card for my GNU/Linux computer for about $80.

Want to use iMac G5 LCD as PC monitor

Hello, here is my problem:
I have iMac G5 that I can't use it (logic board problems, can't finish OS installation) but LCD works just fine! Inverter works fine too.
I want to use iMac LCD instead of my regular (still CRT) monitor.
My question is: is it possible to cut off THIS side of LVDS cable (cable that connects logic board and LCD) and instead that little 30-pin connector put DVI connector so I can connect VGA/DVI output from my PC to that (new) DVI connector that goes into LCD? I hope you understand what I want to do!
If someone has other idea how to use iMac G5 20inch LCD like PC monitor, please post it.

I also would like to try and do the same thing.
I have a g5 imac ALS... just had the motherboard recapped and power supply replaced. It works but freezes up intermittently and the fans are just insane...throttling up to max every 30 seconds for a couple minutes fo no reason (temp is ok), the last time I turned it on I realized that it has become pretty much unusable as a reliable family server. We keep the computer on our kitchen counter and the smaller G5 fits well and matches a whole lot better since it's white.
I don't mind cutting or soldering...is it possible to tap into the main cable? It would make a sweet pairing with a new mac mini.

Imac LCD Help

Hi Guys, well its been almost 5 months that lines have started occurring on my Imac LCD.. however i know its expensive to repair so i did not care initially. However recently i bought the cable to mirror another lcd display to my imac as the LCD started to have alot of flickers.. This is my question.. anyone knows if my Imac LCD displays blacks out.. do you think the mirroring of LCD will be affected?

It mostly depends on where the problem is. If the problem is the video controller, then, yes if one display goes out the other will also, because the controller feeds both the internal LCD and the external display. If the problem is just the internal LCD display itself, if it goes out your external display may still work.

Mid-2011 iMac slow after restore

Hello all, thanks for stopping by.
I have a Mid-2011 12,2 iMac that has been a powerhouse throughout its career. After several large edit projects, no less than 30 full-run shows for national and international broadcast, plus a myriad of other large editorial/graphial projects, I decided it was time to do a complete rebuild and bood to factory settings, seems like a nice way to optimize a system, no? After cleaning my system drive, erasing it, re-installing Mavericks, and re-installing all NLE software (FCS3 and CC) this machine has gone from hero to zero overnight. I have never since day one experienced the type of slowdowns that I am now experiencing. For instance, a 45-minute-source encoding into 1080p, 20mbs h.264 through AME would generally take 1.5 hrs. Now, the same export is reporting an 18-hour run time. Similar times with FCP7 and Compressor. There is an exact mirror of this machine running all of the same software and using Mavericks that has not been restored, and it continues to operate at the speeds that I am used to.
If anyone has experienced similar issues, or has any advise, I would be happy to have you join this discussion. And yes, I have turned my machine off and on again, so we are way past anything elementary at this point.
Many Thanks,
Dave O'Connor

More info...
Sample of current export. These exports are for client review via Vimeo at an increased bitrate of 10 to 20Mbps
17 hours for these settings is not a normal time assessment(taken full course, this media took just over 11 hours to complete). To rule out Adobe issues, I opened a similar project via FCP with similar settings.
Given the time this ran through FCP when the screenshot was taken, I can see that this would be about an 11 hour process as well.
So I decided to dumb it down some, and tried a 1280 export in AME. Similar slowdown. Here's where the kicker comes in, on one of our other machines, an exact mirror of this machine, running on the same server makes this 1280 pass in less than one hour. The exact same machine.
My colleague suggested a ProRes export, even though those are much larger than necessary for this step.
5 hours is a very long time for such a low compression export.
So I decided to try directly through QuickTime Pro. (v7.6.6). I took a ProRes 422 source file into QT and set to convert to ProRes 422(LT).
Again, given the time of progress, this looks to be about 5 hours to finish.
In Activity Monitor, I have noticed lately, and even before the system restore, that some QT processes were not responding. So I checked on those processes.
These activities shut down during all encoding processes, Final Cut Pro 7, QuickTime 7, and Adobe Media Encoder. The mirror machine, during all similar processes does not report back on any of these QT issues.
I need big help on this one, and may have to move this issue to another area in discussions.
I know 100% that there are no issues with any peripherals on this machine. The ONLY thing that has changed since I was experiencing smooth working files, is that I restored the machine to factory settings.
Thanks to anyone who can help point me in the right direction.
Cheers,

Thanks. I didn't realize that I can get up to a TB! Wow! What type of TB do I buy, any suggestions of specific ones? Is there G5 specific Tb disks to install? Or just any as long as they have the right measurement size? And what size do I need to remain within?
