Hi Jaws1431,
I am in the same situation as yours. I ordered a Mini-DVI to HDMI (cheap) adapter to connect my two MacBook to a HDTV.
The first MacBook, under Mountain Lion 10.8.5, isn't working even with all the tips around the net. I haven't tried it under 10.8.4 however.
The other one, under Snow Leopard 10.6.8, is fully working.
Since I want to use the first one with a TV, I'm in trouble.
Two things to do :
- Try with a genuine adapter (if you're in the same situation as mine, aka cheap $3 adapter);
- Try updating to Mavericks (haven't done it myself yet), or go back to Snow Leopard.
I'll let you know when I applied any of those solutions.

Mini DVI to DVI to HDMI Vs Mini DVI to VGA

When I connect my MacBook to my LG 32" HD Ready LCD TV via Mini DVI to DVI connector and DVI to HDMI cable, image is sharp but color seems very pale and washed out. However, when using Mini DVI to VGA connection, colors are brilliant, though images via DVI are sharper.
I tried calibrating the display but couldn't achieve the brilliant colors of the VGA connection.
Is this normal? Any solution for this?
I'm also connecting my PS3 to my TV via HDMI and don't have this problem.

Hey Guys,
I am having a very similar problem.
I have a 35" Westinghouse LCD TV (not the best I know but I'm a college student). I had been using a VGA adapter/cable in order to use my TV as a monitor, but I decided to upgrade (or so I thought) to a digital signal so I purchased a Mini-Dvi to HDMI adapter, etc.
Here's the problem:
My display settings on my MacBook for my LCD TV only allow me to choose either '1280 x 720' or '1920 x 1080'. My TV cannot support the higher resolution so when I chose the '1920 x 1080' setting, the picture comes up with good color quality, but the actual image looks over compressed and does not fill up the screen. When I choose the '1280 x 720' setting, the image resolution looks great, EXCEPT the colors are way off, faded, washed out, etc.
This is problem is so frustrating because I can get the resolution to look good OR the color to look good, bot never both. I have read several forums that touch on a similar issue and have tried all types of monitor calibration but I can't get the color to look normal when the resolution is right.
I just don't understand why the only resolution that fits that of my TV has terrible color??
Help would be greatly appreciated.

I have an HDMI to mini DVI cable issue!

Recently my cable i use for my TV stopped working and i can't sort out why. when connected, my computer goes blank (black) and yet if a video is playing i can hear it. problem is i cant seem to get out of the black screen even if i disconnect from the TV. i have to shut down the computer manually because it seems to be stuck. what could it be??? bad cable? bad port? i do not leave my computer connected all the time, so could it be plugging and unplugging the cable from the computer? it worked simply for the longest time so i can't imagine what happened. i heard maybe a mini DVI/HDMI adapter on my computer might be a good idea too. please advise.

Hi hayesjdr78,
Thanks for visiting Apple Support Communities.
If you no longer see video when connecting your Mac to your TV, try these steps first:
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the systemYou can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.

"Mini DVI to HDMI" or "Mini DVI to VGA" to go to Samsung LN32B460 HDTV?

I recently purchased a "DOA"/defective "Mini DVI to HDMI" converter off of ebay, and the company is making me spend the $10 to return it to China - which I'm not doing (I only paid $10 for it in the first place).
I am wondering if I should buy another one, from a more reliable seller of course, or if I should buy the "Mini DVI to VGA" instead?
I don't play games, so it would be mainly for playing movies and browsing the web. My display is a 32" Samsung 720p (Model LN32B460). It is has a native resolution of 1360x768, 60Hz refresh.
Will I see a quality difference for the basic stuff that I am doing that I should get the "Mini DVI to HDMI" or will the "Mini DVI to VGA" be enough?
Thanks!

I'm attempting to connect my MB to a plasma 50 inch Panasonic TV, and am about to purchase the necessary cables from www.monoprice.com.
I've discovered so far that the HDMI connection directly between the MB and the TV (using the appropriate mini DVI adapter of course - product # 4852 at monochrome.com and an Apple HDMI cable which I'll return to get a better price at monochrome) transmits only video/pictures but not audio.
So far, an old, short RCA (red/white) 2-way audio test cable (again using the appropriate adapter to connect to the headphone jack on the MB) does not transmit audio directly to the TV.
1) Could audio be transmitted from the MB to the TV using a "Coax (RCA) to Optical Toslink Digital Audio Converter" (product ID # 2947 at www.monochrome.com) to connect directly to the TV (in which case, what digital audio cable would I need to connect the converter to the TV)? And if so, would it be stereo or mono?
OR...
2) Should I wait until I get my Onkyo surround sound system (later this week) to see if the RCA cable will transmit directly from the MB to the sound system?
Thanks.

Mini dvi issues

My mini dvi worked perfectly until today. Monitor no detected, and no signal on the monitor ( wich work perfectly with my ps3 and on another computer). I found someone with the same problem here but no reply since 2009
I try on windows ( bootcamp) it doesnt work...
thx

I have this problem too. What I have found is that if the vga adpter is connectto a monitor, I can get a signal from the HDMI-DVI adapter. But when I disconnect the vga adapter, the HDMI-DVI signal goes away too. Anybody know what's going on here?

Mini dvi to hdmi not working in Mountain Lion

mini dvi to hdmi (my TV) worked fine with Lion. After upgrading to ML and trying to use mirroring it says i cannot as it only see one display. TV report no signal.
Any advice?

well.... my problem got solved automatically

I upgraded to mountain lion, now my mini dvi to hdmi doesn't work

I installed mountain lion and now my mini dvi to hdmi doesn't work. I did a disk permission repair, but that didn't help. Any suggestions?

My internet card will only work on 32bit,and it sounds like mountain lion only works on 64bit so that must be my problem. I think I will have to upgrade my internet or go back to lion.

I have one of the old macbooks and wish to hook it up to my tv. do i need a mini dvi to hdmi adapter plus a 3 rca phono lead with a jack for the sound. please help as im useless at this stuff. cheers

First we need to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report if you’re running 10.7 Lion). When System Profiler comes up check the Model Identifier and post it back here.
The Late 2008 model 5,1 Aluminum Unibody and the Late 2009 model 6,1 and Mid 2010 model 7,1 White Unibody have a Mini DisplayPort. The Early 2006 model 1,1 through Early 2008 model 4,1s plus the Early and Mid 2009 model 5,2s have Mini-DVI ports. Each would take a different adapter to connect with the TV.

Mini DVI to HDMI problem, won't play DVD movie full screen on TV

I use a mini-DVI port adapter with a DVI to HDMI cable to a 32" 1080p TV. When I play the DVD player screen on the TV and select full screen mode, the screen shifts back to macbook and displays full screen on the mac and the TV displays a black looking background. This issue only started after installing Lion.

Thanks for that. I have a Y adapter (3.5mm stereo headphone jack to RCA sound just like you said). Under input options on my TV, I can select either HDMI1 input (which gives me video only) or AV1/S input (which gives me audio only) - not both at once...Could you explain how I can get stereo audio on my TV?

Mini-DVI to HDMI Issues

I have an early 2008 Macbook and have been using a Mini-DVI to HDMI adapter and HDMI cable to connect to my TV. It was working great until I upgraded to OS X Lion. Now the video is laggy/glitchy on the TV and the computer when the cable is plugged in. Any help?

Try gently moving the adapter into different positions. My mini-dvi to dvi adapter will only work if it is tilted upwards at about a 20 degree angle relative to the tabletop. I usually wedge a pen or a pencil below it to hold it at the proper angle. It's a little redneck, but I like shopping at walmart and only spent $5 on the adapter.

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.

I am trying to connect my Macbook 4.1 Black to my Samsung UE50F6400 using a mini DVI to HDMI adaptor

I bought the UE50F6400 samrt TV. It has 4 HDMI ports. HDMI 4 is HDMI/DVI, HDMI 3 is normal, HDMI 2 is (ARC) and HDMI 1 is (STB).
reading the connection diagram it shows Laptops are to be plugged in to HDMI 4 (HDMI/DVI). But when I plug a HDMI cable in and the other end to the adpator while the mini DVI connection is in the Macbook DVI port. All that happens is the Macbook (4.1 black) screen just flashes blue. This is the same for HDMI 1 & 3, however when it is in HDMI 2 (ARC) the Macbook screen displays. I tried switching TV of and rstarting macbook but still no display on TV. I tried changing display setting such as resolutions and refresh rate on the display preferences and still no display on TV.
Please can someone help?
I am think I may have to return the Mini DVI to HDMI cable and get a HDMI to DVI > DVI to mini DVI and do it that way, means buying 2 adaptors.

You have the display set in Extended Desktop mode with the MacBook as the main screen. The Menu Bar and Dock will be on the MacBook display and your background screen on the TV but you can move the cursor onto the TV screen.
In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen.
The TV will now have the Dock and Menu Bar and windows will open on it. But you can move the cursor to the MacBook screen and move windows from the TV over to the MacBook screen.
You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box. That will give you the same screen at the same resolution on both the MacBook and the external monitor.

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.
