Hardware :: Connecting PowerMac To LCD TV Display
Jan 3, 2008
I just bought an LG 32" LCD TV (model 32LB9DB). It has 3 HDMI connections on the back, so, I bought a DVI-HDMI cable and connected that to my PowerMac's DVI port (PowerPC G4, 1.75 GB Ram, ATI Radeon 9000 Pro video card) and then to the TV's HDMI port. I can see my desktop and everything, but, the image quality is very poor no matter what resolution I choose. It looks like the digital signal is being converted to an analog signal before being displayed, so, text is blurry and the overall image looks very poor, not at all like a computer monitor. It looks like a computer image displayed on an analog TV.
I thought that if the TV had digital video input, I would get a 1:1 pixel resolution when attached to my computer, but, I guess not. Am I doing something wrong with the setup? I've already looked at all the TV's settings, and tried lots of different ones, but, the image quality doesn't improve. Here's the detail about my Display:
ATI Radeon 9000 Pro:
Chipset Model:ATY,RV250
Type:Display
Bus:AGP
Slot:SLOT-1
VRAM (Total):64 MB
Vendor:ATI (0x1002)
Device ID:0x4966.........................

I was able to get this machine to connect to my wireless home network, yet I still get the "Server cannot be found" error. Have tried with the old IE program, then I downloaded an older version of Safari on my iMac and transferred it via disk to the PMG4. The safari loaded fine, a window opens, yet it will still not connect. There must be a setting I'm missing - can anybody tell me what it is?

We have a PowerMac G5 machine which won't boot at all. you can hear it turn on and everything (including the chime at bootup) but you won't see anything show up on the display.
Also after several minutes, you will hear a very loud noise come from the machine, the fan you can tell is extremely loud. Not knowing this stuff very well as i'm more a PC tech than Mac, what are some options to troubleshot?

I have a last model G5 with dual 2.5ghz and 4.5 gigs of ram. It also has the 7800gt video card.After I start it up it runs for about 15 minutes and then the display goes blank and the system fans go full out. I've tried resetting the PRAM, PMU, VRAM, all of those things...the last thing I have is the video card to test.Also the power supply was just replaced by a Apple Repair Center under extended warranty.

So, I think my PM G4 finally died. I had been using it as a media annex (not center) in my living room since my 22" Apple Cinema Display still works fine. Now I'm stuck with a 22" monitor that can't be connected to anything. I've been looking into what can be done. Based on an Apple Support Document, there is a M8661LL/A part called "Apple DVI to ADC Adapter" that I think will do the trick. If I get it, I should be able to hook my PowerBook G4 up to it, right? If so, the next task is to find the sucker. searching online for the part number didn't yield much, but I did find a nearly identical product number, the M8661LL/B on Amazon for $90 (yikes!!). The only difference is the suffix letter. But I don't know enough about this to really know if it'd work.

I seem to have trouble connecting my mpb with certain hdtv's - sony, toshiba. the screen resolution seems to always be bigger than the actual tv size, so the ends are cut off, such as menubar and dock can't be seen.
i can't change the settings on my tv, and the display settings on the mbp are limited. is there any app which can adjust the screen size manually? such as a zoom out tool?

I've been searching around for some time to try and figure out how to hook up my 360 (and it's HDMI output) to my mac pro (quad, 7Gb ram) and 30" cinema display. Apple lists this on their site: [URL] but it's designed as a video capture card, so I'm not sure if it's appropriate for using simply to play the 360 on. Are there any other pci express cards or units which will allow me to take the output from the 360, input it through my Mac Pro and display it on my cinema display without lag, wonky setups, or hijacking anything?

I know this has been asked a hundred times; can you hook up your 360 to cinema display but all the threads are from years ago and people keep saying there will be converters and such soon.
Mac Pro, 30" ACD, Apple LED 24" display, and 360 and I have a uMBP.

I am using a 23" cinema display as my main screen connected to my mac book pro. It is working fine but I was wondering if I could remove the usb connection leaving only the DVI connection and the Firewire connection. (So I have one more usb port to plug stuff) I know for an IPod both were provided in case you don't have a firewire in your laptop when only 1 is needed.

I own an Apple 27" Core i7 iMac. I just bought a Dell 3008WFP (30" LCD Display) [URL]. It has full size display port, hdmi, vga and dvi. As you know though it's a 30" so it needs "dual-link" DVI from whatever is driving pixels to it. So the iMac, to my knowledge only has Mini Display Port, right? How do I get the iMac to push the 30" at full resolution?

My dad has bought a 24" LED Apple Display to use as a secondary screen with his 2008 Mac Pro3,1.
He called Apple before he bought it, and the guy said he needed a Mini DisplayPort to DVI Adaptor, so we have one of those... and it doesn't fit.

I have an older 23" Mac HD Cinema Display monitor with an ADC connector. I just purchased a 15" MacBook Pro and want to use the 23" display. The Apple Store where I purchased the notebook sold me a DVI to MiniDisplay. But I was told I would need to buy an ADC DVI adapter that Apple no longer carries. EBay has many Model A1006 DVI ADC adapters for sale. It looked like it has the plug configuration I need to mate the two adapters.
Basically, I need a Female ADC plug that connects to the Cinema Display and a Male DVI to connect to the DVI to MiniDisplay adapter I have now. I called Apple Support and was told "it should work" but they won't guarantee it will since they don't support either the monitor or the A1006 connector. Can anyone who has successfully done what I'm trying to do please let me know? Will the Model A1006 DVI adapter work with the DVI MiniDisplay adapter?

I got an 1.33 Ghz G4 iBook logic board, given to me as a working part. However, nothing else that goes along. I do have all the basic cabling such as speaker and power button, flex cables and such. Also got myself a new external AC power adapter. Now, I do not intend to use this as a laptop, thus, I will not be looking for a battery, just AC use. However, there's a big problem, I've no screen. I know there's this software hack that allows to connect an external display, in order to have a "mirroring" desktop.
I suppose that'd be achievable if I had the original screen to actually do the hack, but I don't have it. So, is there a way that I can just directly connect an external display and completely forget about the internal one? One more thing, suppose I can't do what I have in mind, if I actually found and borrowed an internal display, would I be alright if after the hack I give the internal display back to it's owner and continue with the external?

I just bought a 23" ACD and I'm having trouble getting it to work with my 17" Powerbook. I checked it in the store before buying and it worked fine, but at home it's not responding. The display is recognised in Preferences and is giving me a choice of resolutions, the light is on, but I can't get the screen to show anything. I've tried adjusting the brightness to bring up an image to no avail, turning mirroring on, and closing the lid on the Powerbook then waking it again but nothing gives me an image on the 23".
My Powerbook is a 1GHz 17" with a GeForce4 MX 64 MB.

I bought a second screen a few days ago, the 23" LG M2394D. I have got it connected to my 24" Aluminium iMac. The resolution of the monitor is 1920x1080 and the iMac is 1920x1200. System preferences lets me assign the different resolutions on the different screens, but the quality on the second screen at 1920x1200 is very dodgy. If i put it to 1650x1050 it looks better, but not as good as the apple display. I have also noticed that the picture is 'too big for the screen', i.e. there is some of the picture outside of the screen area that i cant see. I have the screen connected via the Apple MiniDVI to dvi connector and then a DVi to HDMI cable into the screen. Is it the HDMI that is causing some of the problems? would a straight DVI cable work better? Here is the screen: [URL]

I am trying to run my new Macbook Pro as a media center. I ordered a display port to HDMI adapter which should arrive shortly. Will this drive audio through the HDMI? If not, what is the best way to get audio from my Macbook Pro to my home system to play through my speakers?

I am new here, I have been watching the forum but have not needed to post until now. I have a june 2.8 MBP running snow leopard and I am having problems with Mini DP to HDMI. I have a convertor to go direct to hdmi from mini dp but when I use it to watch movies the color is really dark. It is almost unwatchable.
It is not a hardware thing because when I boot into windows 7 I can watch the same file with the same hardware with no issue with darkness.
I was wondering if anyone has come across this issue in snow leopard. I have searched mroogle as well as good and could not find anything.

My macbook pro has been connecting to my TV appropriately for months. The display is suddenly changing to a different default when I connect now. It was fine two weeks ago and has done 3 software updates in between. I have not loaded other new software. When the thunderbolt connection is made, both screens turn blue, then both display a screen resolution formatting that doesn't fit the screens.
Info:MacBook Pro (13-inch Early 2011), Mac OS X (10.7.3)

I have a 23" Apple Cinema Display (the older model in the clear plastic casing) with a Dual 2ghz G5. I'm not to technically inclined yet as I just got into computers and decided to give macs a try. I just got a xbox 360 and was hoping to connect it to my cinema display. Just wondering if this is possible. From what I understand my G5 has and DVI out which is why I had to get a DVI to ADC adapter for it to work with my display. Microsoft sells a VGA adapter but I'm guessing that will not work with my display. Also if it is possible what type of device would I need to use the monitor with the xbox and the G5 together? (I know I can't use them at the same time but alternate so I don't have to keep unplugging and hooking up cables every time I go between machines).

I'm wondering if it's possible to connect a 23" Apple Cinema Display (1920x1200) to a PS3. The Cinema Display is one of the older models, and it only has ADC. However, I've heard of switchers such as the Gefen HD Mate that would make this possible. These are hard to find now (and if they are available, they're ridiculously expensive). Are there any other ways to make this work?

I have a new MacBook Pro 17" computer. I want to play a DVD through the computer to a Toshiba 26" flat screen TV, using a mini port to HDMI.
At first nothing happened, then after much fiddling I got the Apple Spiral Galaxy image on the TV and my usual desktop on the computer. I then discovered that I can move the cursor from my desktop across to the right, where it disappears from my computer screen and appears on the left side of the spiral galaxy on the TV. So it's like I have two side-by-side screens, the Apple galaxy on the left, my computer on the right. In addition, I keep my dock on the right side and it's barely visible on the right side of the galaxy screen.
Incidentally if I play the DVD I can drag and drop it to the right so it slides off of my computer and onto the galaxy. But I know that's not the real solution.

I'm new to the forum, but not necessarily new to Apple. I have a aluminum MacBook and have it connected via display port to a Dell monitor (have a cinema display on order from macmall due in tomorrow!). My question is while I have the MB connected to the display, is there a way I can have the laptop lid closed and prevent the computer from going to sleep?
