IMac Mini DVI output resolution

Hi.
My friend tells me that the new Intel iMacs can output display resolutions that support the 30-inch display. However, the technical specs state that it only supports a maximum of 1920 x 1200 resolution.
Why is the maximum capped at this resolution, is it because of the mini-dvi connector it uses or an imposed limitation by Apple? Surely the iMac graphics cards can output to 2560 x 1600?
If someone could definitively tell me whether the new Intel iMacs can support the 30-inch display or not that would be much appreciated.
Thanks!

Hello,
The Intel iMacs offer mirroring and dual-displays at resolutions of:
Digital resolutions up to 1920 by 1200
Analogue resolutions up to 2048 by 1536.
This is a grpahics card limitation and not the MiniDVI adaptor.
Apple's 30" display requires a dual-link DVI to drive it which the iMac does not offer. You can connect any physical size display so long as the resolution is less than or equal to those listed above.

Problem with iMac mini DVI output to TV via VGA

Hi
I've searched these forums and Googled but haven't found the answer to this problem!
Basically, I'm trying and so far failing to connect an iMac that I bought in mid 2007 (v 5.1, OS X 10.6.5) to a new HD TV (Sony KDL-32EX403). I'm using a Mini DIV to VGA adaptor from the iMac with a VGA cable that goes into the 'PC' input round the back of the TV. When I try and select the 'PC' function from the inputs menu on the TV, the icon is greyed out.
No matter what I try - turning mirroring on and off, changing resolution, unplugging, restarting - it makes no difference. Weirdly the display menu does acknowledge that the Mac is connected to a Sony TV and gives a list of resolutions to choose from.
However... when I tried connecting my PC notebook using the straight VGA cable (output on the PC, input to the TV) the image appears fine. So I took the cable out of the PC, screwed on the VGA-DVI adaptor and plugged it back into the Mac and it worked! However when I switched back to TV mode I could not switch back to PC input, the icon was once again greyed out.
Sigh...
I see no reason why this doesn't work without this awkward workaround so if anyone can help or has had a similar problem please shout!
Thanks

I have my Macbook (early 2008) hooked up to a 19-inch TV I use as a second desktop. You won't find any cords that go straight from mini-DVI to HMDI, and even if you do I wouldn't recommend them. You'll have to get an adapter cable that goes from mini-DVI to DVI and then get a DVI to HDMI cable. I got the Apple-made adapter (about $20) even though it's more expensive because apparently third party ones can have problems. You can get a DVI to HDMI cable anywhere, they can run expensive but I got one off Amazon for less than $10.
That connection is video only so yes, you'd need a different connection for sound. As to how you hook the sound up, it depends on what you want to use for sound. If you want the sound to come from the TV speakers then you'd have to use a different cord than if you wanted to hook it up to a sound system. If you let me know I can explain what you'd need to do for that. Hope this helped

My mini dvi output port is no longer working (2007 iMac) please help!

My mini dvi output port is no longer working, can this be replaced or do I need a new motherboard? (it's a 2007 iMac, no longer under warrantee. Long story short when I was out of town someone cut my power cord on my tv I went to turn the tv on and looked at the back of the tv to see if there was any loose connections and found the cord sliced 3/4 of the way through. I must have bumped the cord and it sparked and made a loud pop noise. Well it fried the tv (which has since been fixed) but everything that was connected to it (my ps3, receiver, and my iMac) ports are all not working now... (and yes i did try new hdmi cables to see if it was just that) If this is a hardware issue what exactly is needed to fix this? A new main board? Any feedback would be great on this. I took it to apple and they said $650 to replace the motherboard... Was just wondering if this port can just be replaced or if it is a part of the main board and that does need replacing. Everything else works fine on all three things (ps3, receiver, imac) just the outputs are fried on them. Is there any other way I can do video out of my iMac other than mini dvi? I'm not paying for the repair so I don't mind having apple replace the board, but for $650... I may as well get a new iMac for $500 more...

If Apple said the motherboard is gone, that's your answer. Even if you were to find out the port isn't part of the main board, it's all connected when you're talking about a power surge/short as you described it. And yes, I'd never invest $650 in a 5 year old computer.

Can you view movies through the mini-DVI output?

Anyone know if you can watch rented movies on a TV with the mini-DVI output to video?

Anyone have any feedback on whether or not you can output rented movies through the mini-DVI to watch on a television?

Thunderbolt iMac - mini-dvi to HDMI - Image not sharp on TV

I am trying to use my TV as a second monitor for my newish iMac. I used to do the same thing with my macbook (2006) with a mini-dvi to HDMI adapter. The signal then was crisp and typical of 1080p. I recently tried two different mini-displayport to hdmi adapters to output my monitor from the thunderbolt port of the iMac. The first was a cheap one and the second was a better one. Each time, the TV says the signal is 1080p, but the image is blurry, although sound does work.
The TV and the HDMI cable is the same as my old macbook which worked perfectly. Also, I have been using Windows 7 with bootcamp and the image is the same. This limits the problems to the graphics output, port, or adapter. As multiple adapters still have issues, I don't know it anything else may help it.
Is there much possibility that there is something with the computer, either graphics card or port itself, that could cause this, or maybe something software wise that could be an issue?

Check under the system settings to make sure you are putting out the correct signal. If it is set at the correct resolution then your TV doesn't have enough Hz. Hope that helps!

IMac mini DVI to HDMI problem?

Hi,
My iMac through mini DIV to HDMI doesn't detect a signal on my tv, I am running on a 24" early 2008 imac on lion 10.7.5. I've tried two different mini dvi to hdmi cables, two different tv's and different hdmi ports nothing seems to work. It detects my tv's and the screen flashes blue but has no signal each time, I am able to change the resolution etc of the tv's but it just stay black. I can set up a mini dvi to vga fine with my tv just not mini div to hdmi has anyone come across this issue?

yeah there is a setting called skip input it has the 3 ext and 3 hdmi, i tried skipping it but it to hdmi 3, which is the port tht it was connected too but it didnt work. Any more ideas?

Combined audio & video from iMac mini DVI & headphone ports to HDMI to TV

I presently have my iMac connected to my Sony Bravia tv so that the video goes from the mini DVI port through a converter to HDMI to a 25 foot cable, a HDMI coupler and another 25 foot cable to the TV. The video quality is good since I use 24 AWG cables. The audio goes from the headphone port through a 50 foot 3.5 mm cable to a converter to RCA stereo cables to the tv. The audio quality is not very good with this setup and I would like to send the audio over the HDMI cable with the video so that I would have only a single cable over the 50 foot run and could use a HDMI wall plate for a neater installation. I am wondering whether anyone has tried this somewhat expensive solution to my kind of problem, and whether it worked. Atlona DVI + Digital Audio to HDMI Converter. Model: AT-DVID-HDMI

Not sure if it would work. The audio input is described as +audio (SPDIF) input+ which is not analog or the Toslink optical digital. SPDIF is a digital format, so you would need another converter. And since the video input is full DVI, you'd need a different adapter for the iMac's video output.
Considering the complexity, additional adapters, rather long travel length, and $199 price for the Atlona device, depending on what you want to show on the HDTV, you may want to consider an Apple TV. The older 40GB version is $149 at the Apple +Special Deals+ page. You can then stream your content wirelessly, and not have to worry about any cabling. But obviously, an Apple TV does not stream everything that that iMac can play, so it would only work if what you want to show is stuff you can play in iTunes. Plus you may want to see what Apple introduces at the 1/27 special event.
The iMac's audio output port doubles as an optical digital port, with a Toslink adapter, so if the Sony Bravia has optical digital input, you may be able to run a Toslink cable. I believe 50 feet is too long, so you would need some type repeater at the midway point.

How to hook up a Sharp Notevision PG-M20X projector to a Mini DVI output.

After this has been discussed on a few forum discussions before, but without a solution being provided, I have found myself in the same situation. I tried connecting the above mentioned projector on my Macbook and only got a black screen, even though the Display settings could find the projector with the correct product name and resolution settings. I tried all the various adapters (Mini DVI to DVI, both with DVI-D and DVI-A cables and the Mini DVI to VGA adapter.
In the end I got it to work with Apple's Mini DVI to Video adapter, using an S-Video cable to connect the adapter to the projector. The resolution is not quite as good as it was when I used my trashy, ten year-old PC on the projector, but I guess that's the price you have to pay when you are buying a fancy hi-tech laptop like Apple's Macbook for over £ 1000.
The staff at the Apple helpline as well as the Apple store were as clueless and unhelpful as usual when it comes to anything outside of the ten most FAQ's.
Hope this helps a few of you out there and saves you from going berserk in the Apple store.

Hi There,
Whenever I hook up a projector that doesn't work with my MacBook (when it shows just a blank, black screen), the first thing I try is going to System Preferences > Displays and setting the resolution of my desktop to 800x600.
Nine times out of ten, the projector starts right up and works perfectly.

IMac, mini-DVI to HDMI connection stopped working

Hi,
I recently switched from my good old white plastic iMac (late 2006, 20", Lion, 10.7.5 ) to another, slightly newer alu-body iMac (mid 2007, 20", Mountain Lion, 10.8.3).
As before I used a Samsung SyncMaster as "desktop extension" connected via mini-DVI to a mini-DVI to HDMI adapter ( http://www.amazon.de/gp/product/B0088BUT40/ref=oh_details_o02_s00_i00 ).
The Samsung monitor is recognized, system information is able to report about it, system logs are fine, nothing special - BUT: no image. The Samung display remains dark.
I already searched the internet, the community, the whatever came to my browser.
I think it is an HDPC or windowserver issue but I have no idea if I can fix it.
Any ideas?
Sven

Do you have the correct HDMI input selected in the TVs menu...?
Aditionally, there might also be settings for connecting a PC to the TV.

Macbook air mini dp output resolution / full screen app issues

I've successfully connected my new macbook air 13" to my LED tv with a mini DP to hdmi adapter + hdmi wire. I am able to get video and audio (obviously.)
My issue is that no matter when resolution I try (1080p, 1080i, 720p, etc) and wether I am "mirroring" the display or "extending" the display,
My samsung 46" LED tv can not get full screen there is always black bars on the left and right.
When I connect my PC via VGA wire there are no bars and it is in full land scape view.
Also I've noticed in lion that full screen apps show up as the "linen wallpaper" on the second display.
the only way i can slightly alleviate the problem is full screening a video within youtube but not within the OS it self... even then there is still black bars which is weird because when i use the TV as a extended monitor the wallpaper is using the whole display just full screen video has black bars.
I am unable to get 1920 x 1200 output display to my HDTV is this possible? is it my mini DP to hdmi adapter that is at fault?
thanks in advanced to whoever helps sorry about the long post my brain is scattered on the issue because my VGA connetion works fine i don't understand why HDMI + mini DP has worse resolution...

No, it doesn't list the resolution explicitly like that - the top few items in the list are "480i", "480p", "720p", "1080i" and "1080p", each with a small TV icon to the right. Non-television resolutions follow, and are listed with explicit pixel dimensions (and no TV icon), but the list stops at 1440x900, the native resolution of the MacBook's built-in display; it doesn't list resolutions higher than that.
Needless to say, I've tried every setting in the entire list, and they all suffer from the same problem of displaying shrunk down on the plasma TV with a margin around the desktop.
I wonder if the difference between your Display control panel and mine is that I'm running Snow Leopard? (Sorry - no screen grabs to show, I'm at work right now)

IMac Adapter Out Questions (Mini-DVI to VGA)

Hi everyone,
I've got a 2.4ghz C2D 24" iMac. For two years I had the iMac hooked up to my LCD tv via this route: iMac -> Mini-DVI-to-VGA adapter -> 75' VGA Cable -> LCD TV. I recently upgraded my TV, and no longer have a VGA port on the TV. I'm not looking to replace any cables because it's quite costly, and at this point in my life I'm not willing to spend that much to replace the setup.
My new TV has a DVI-D port on it. This is a very random connection, and yes, it is DVI-D (NOT DVI-I or DVI-A). What I'm wondering is if I get another adapter, a DVI-D male to VGA female adapter, will the iMac recognize the TV? I'm not sure how the video card treats the exterior Apple Mini-DVI to VGA adapter and am wondering if a simple $5 adapter will suffice.
Any help or information regarding this would be great.

That is a common adapter and it works, but the way it works is digital-to-analog. In other words, you plug the male DVI end into your computer and the female VGA end into the VGA cable (which then goes to your monitor/TV/whatever). Unfortunately it would not work if you went DVI(Mac)-to VGA cable-to DVI(TV) because it cannot convert the analog signal back into digital.
Those adapters are handy to have anyway so you could always buy one and try it out, but I'm sure you'll just get a blank screen (or the dreaded "no signal" message). Sorry

Mini DVI to VGA in Mac and Windows XP with Bootcamp

I just bought 13in MacBook the first time so I am new with this system.
I am trying hook up MacBook Mini-DVI output to Panasonic th-42pd25up (EDTV) with VGA input for PC. I hooked it up using Apple's Mini DVI to VGA adapter to TV. (TV also has HDMI input which TV manual says not to use it.
TV's resolution are :
640x480 for 4:3 aspect ratio
852x480 for 16:9 aspect ratio
I have two problems watching streaming video at 300 to 700mbp of soccer or cricket sport broadcasts.
1. In Mac system, I only get blue screen of computer on TV with out any writing or pictures or tool bar.
2. In Microsoft XP using BootCamp I get "no signal" on TV. Would I have success using Parallels software?
I am missing some important games!!!
Thanks for any guidance give me.

This is normal in extended desktop. You can drag anything you want from the main screen to the external screen. I prefer it this way when I am watching MLB.TV. I keep the game on my external and use my internal work surfing and other stuff.
You can use the F7 key to switch back and forth

Mini-DVI to HDMI Cable Not Recognized...

Hello all!
I just bought http://www.amazon.com/gp/product/B002LEY28O/ref=oh_details_o00_s00_i00?ie=UTF8&p sc=1 from Amazon.com and it arrived today but when I plugged it into my iMac (Early 2008) literally nothing happens. I have tried power-cycling everything, starting up things one at a time, everything. (Searched the internet to!) Here's the specs of my stuff:
iMac (Early 2008):
2.4 GHz Intel Core 2 Duo
ATI Radeon 2400
2 GB 800 MHz DDR2 SDRAM
1 mini-DVI output port
||
I am currently staying in a hotel so I do not have all of my usually electronics but I have tested it on an LG HDTV and a ViewSonic HD computer monitor and both do not work, it just display "no signal" and the iMac doesn't know that anything is different, the blue screen that is supposed to fade simply doesn't and under the "display" section there isn't an "arrangement" tab and clicking "detect displays" just freezes my computer (cannot move mouse) for 1-2 seconds. I ruled out the HDMI cable that I have by using it with my Xbox One and it works fine. Any suggestions?
Thanks Everyone!
Also, you do not have to explain it to me like I'm 5. I am well capable of making my way around a computer.

Hello Ratnik,
I'm having the same problem. Below is my question.
If you get any closer to a solution, might you please send me the result?

Connecting to a Samsung TX-R3079WH HDTV w/Mini-DVI to HDMI

Greetings, I have a Samsung TX-R3079WH 30" HDTV that has an HDMI input (which works just fine via cable box input), and I have a Rev C Powerbook G4 12" 1.33 GHz with an nVIDIA GeForce FX Go5200 64 MB AGP graphics card with the mini-DVI output (which works with the converter to a 17" CRT via VGA).
I recently purchased a 4 m Radio Shack DVI to HDMI cable to connect the PowerBook to the Samsung TV. I am connecting the DVI cable through the DVI to Mini-DVI converter from Apple to the PowerBook.
At first, when I had the Mini-DVI/DVI connector attached to the laptop, I had the TV turned off and plugged in the HDMI cable to the TV. I turned on the TV, and my computer's display definitely recognized the external display. The problem initially was probably a refresh rate/resolution problem I guess, since the TV was reporting "No Signal" but the laptop definitely recognized an external display, which had its own icon in the System Preferences Displays panel (running at what looked like 640 x 480, definitely smaller than the native res 1024 x 768 of my primary display).
Anyhow, I didn't recognize what the problem was then, but now when I try and connect the DVI/Mini-DVI to the HDMI, all I get is incessant flashing from my primary display as it tries to decide whether or not there's something attached.
Any suggestions on getting this setup to work? Thanks in advance.

never mind found the mirror display function.
