Mini - DVI/HDMI - Onkyo TX-SR674 - Philips 42" LCD | Problem

OK, I just got my new Mini (1.66 Core Duo) to hook up to my Philips 42" 1080P HDTV LCD. I have the video signal going via a DVI to HDMI cable through my Onkyo TX-SR674 Receiver. The reason for this setup is that the Onkyo receiver controls my video switching and sends the video signal through only one HDMI cable to the TV. That way with one press, I switch audio and video signal at the same time.
Well, the Mini works great with this setup... until... I start up Safari. As soon as Safari starts, I lose the video signal. I can run iTunes, System Utilities and it doesn't cause this problem. The video signal flickered a bit during a repair of permissions, but as soon as Safari brings up the Apple page, I lose the signal.
My video res is setup at 1920x1200, 60 Hz.
Any idea why this is happening. What in the Safari browser would cause the video signal to all of the sudden freak out?
Thanks!
Mac OS X (10.4.9)

OK, I had no problems with a direct hookup to my TV and bypass the TX-SR674, but I was not satisfied with that solution!
I found other programs and not just certain webpages in Safari that caused the display to freakout in the old mode, too.
I downloaded and installed switchResX and it had two (2) 1920x1080x60 resolutions listed. When I choose the other 1920x1080x60 resolution, it works fine. Doesn't freak out. Not sure what is different about the second setting, but so far it seems to work OK.
If worse comes to worse, I could always lower the resolution and just have the TX-S674 upscale it to 1080 for me. I may do this eventually anyway since everything on the screen is a bit too small to read from my couch. Not sure on that yet.
But anyways, just thought I'd report back on my results. Thanks!

I've just hooked my 20" iMac up to my Toshiba 37" HDTV using a mini dvi-HDMI adapter, and works well, EXCEPT for the green tinge (or hue) that is showing up on my TV. Any suggestions or ideas?

I've just hooked my 20" iMac display up to my Toshiba 37" HDTV using a mini dvi-HDMI adapter, and everything works well, EXCEPT for the green tinge (or hue) that is showing up. Everything else looks pretty good though..... The color that is on my iMac is still good, Its just green on the TV.
Anyone have suggestions or ideas?

Try opening the Display System Preferences, then click on the Color options in the Display preferences window that appeared on the Toshiba display. Click on the Calibrate button and follow the instructions for creating a custom ColorSync profile that will hopefully solve the green tinge issue. The Apple Display Calibrator Assistant software that launches when you click on the calibrate button will walk you through the process.Assuming that the green tinge is minor and that you don't have a more serious cable or hardware issue, I am hopeful the results will be worth it.

Mac Mini + DVI- HDMI + Toshiba 42RV530U = black screen

Hi all, I have a new Intel Mac Mini 2GHz and a Toshiba 42RV530U REGZA HDTV that I'm trying to connect, with only a black screen so far.
I believe the DVI output on the Mini is working - I can at least get a picture with a DVI-S-Video cable, but it's obviously lower resolution. The DVI-HDMI cable works - I tried it on our cable box.
When the DVI-HDMI cable is hooked up to the HDMI-1 input on the TV, the "No Signal" warning vanishes, but it's replaced by a black screen. No amount of fiddling with SwitchResX has worked so far.
I've tried coming up with values for SwitchResX based on these numbers from the manual (don't know why the H Freq and V Freq give 2 values for each). I couldn't get exact values, but pretty close. I'd ideally like to get 1080p working.
Name Resolution Vert Freq Horizontal Freq Pixel Clock
480i 720 × 480i 59.940/60Hz 15.734/15.750kHz 27.000/27.027MHz
480p 720 × 480p 59.940/60Hz 31.469/31.500kHz 27.000/27.027MHz
720p 1280 × 720p 59.940/60Hz 44.955/45.000kHz 74.176/74.250MHz
1080i 1920 × 1080i 59.940/60Hz 33.716/33.750kHz 74.176/74.250MHz
1080p 1920 × 1080p 23.976/24Hz 26.973/27.000kHz 74.176/74.250MHz
1080p 1920 × 1080p 59.940/60Hz 67.433/67.500kHz 148.352/148.500MHz
I've also tried repairing permissions, rebooting many times, deleting the windowserver.plist files, zapping the PRAM, etc. SwitchResX identifies the TV as "TSB-TV", which sounds the same as other posts with different Toshiba TVs. I'm able to remote into the Mini via Remote Desktop Connection to play with settings, etc.
Any suggestions? Would a DVI to Component cable work? The TV does have an analog RGB in, but this won't support high def. Thanks for any help!

An unforeseen twist... I tried hooking up the Mac Mini to a DVI computer monitor, also with no picture. When I hook up my Powerbook to the Toshiba via the DVI->HDMI cable.... Picture! So, looks like my new (refurbed) Mac Mini has a bad digital video output. Seems a little strange though, since the analog video output on it is working fine.
Off to the Mac store tomorrow.

My macbook mini DVI-HDMI won't connect

i recently updated to Lion, and now my mini dv-hdmi wont work? i have the adapter from apple and the HDMI is a belkin dvi-hdmi, and now it wont even connect to my tv does nothing. is this a known software problem? : i used it before the update.

Unfortunately I am having issues with my HDMI connection from a Late 2008 MacBook to a 37" Phillips HD TV. When I connect the two a notice stating that "Format is not Supported" appears on the TV screen. Why did you do this to me Lion, WHY? I was unable to make a presentation because of this fact. Unsatisfactory!

Mini-DVI to VGA cable... LCD TV has female input

I recently bought a mini-DVI to VGA adapter from an Apple store, to connect my MacBook with a broken screen to a UMC LCD TV. When it came to plugging the VGA end into the TV, I realised it has exactly the same connector (female I think) as the TV. This obviously means they will not connect, and I haven't been able to find a connector that will do the job. I was surprised to find that after a fair amount of searching no one else appears to have had this problem, so maybe I'm being stupid somewhere here. Thanks for help.

You need a VGA male-to-male cable to connect the Apple mini-DVI to VGA adapter to your LCD TV:

Using Mac Mini dvi to vga on an Philips plasma

Hi
I have an Philips plasma tv that dosn´t have an dvi. So I use the vga instead.
But I get the message non supported picture format. Sorry for my bad translation från swedish. The tv is an Philips 42PF9945. Please if any one can help me

If you have a second Mac or a PC at your disposal on the same network as the mini, I suggest you try making a VNC connection between the mini and the second computer. In this manner you can control the mini remotely and make different selections in Display Preferences on the mini from the other computer. Hopefully you will be able to find a resolution that will cause the screen to come to life.

Cannot connect macbook pro to TV via mini DVI/HDMI adapter

I am trying to connect my Macbook Pro (mid 2009) to a TV using a miniDVI to HDMI connection. This used to work fine without any issues. It stopped working after I upgraded my OS to snow leopard. In addition, when I go to the display settings, it will not detect the display. BUT when I connect the wires, the computer goes to a blank screen like it is trying to mirror.....help!

No sound through mini DVI-HDMI adapter.

I've never had a problem hooking my Macbook Air up to my TV through the HDMI cable before. I believe the change happened after updating to 10.8.2, but I can't be sure. When I plug in the adapter, the picture goes through to the TV (just as before), and in the Sound settings panel it has the option for playing through the TV (just as before), but no sound. Using the same adapter on a Macbook Pro running 10.7 - no problems.
Thanks for any help or tips in advance.

You already tried most of the steps to get this working, but I do suspect the ATI/AMD driver has somehow been corrupted.
You already tried the AMD drivers from HP's site, so I would give the drivers directly from AMD. Worst case scenario is it doesn't resolve the issue. The linked driver is what was returned when selecting the options for the notebook on AMD's driver page. Notebook>Radeon HD>Mobility Radeon HD 4XXX Series>Windows 7 64bit.
Let me know what happens.

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 problems...

Hey guys, I hope you can solve my problem. My late 2008 MacBook...

...I am having trouble connecting it to my 42" Panasonic Plasma 720p. I purchased a mini dvi - hdmi adapter and plugged everything in and just got a blue screen on the macbook and nothing on the tv. I am sure that the right input was used on the TV. I also tried using the same setup on my other 32" lcd, but had the same problem with the macbook. What am i doing wrong. Should I try a mini dvi to s-video and use that or would the picture suffer. Since my tv has the hdmi, I would really like to use it...I called apple, but the referred me to the forum or pay them $50 to try and figure out the problem. The tv has 2 hdmi inputs and I tried both of them. It also has s-video and component inputs, but no vga...Please Help...

I am having an identical problem. Unfortunately, I cannot quite follow the syntax of the response to the original post. I have a Macbook 2.1 and I am trying to hook up to an LG 32LH20 TV. I got the Mini DVI to HDMI adapter and an HDMI cable at eh Apple store. Connected the HDMI cable to the HDMI IN jack on the back of the TV. They also sold me an audio cable with the 3.5mm jack on one end and the red/white AV plugs on the other end.
Once all of the cables are hooked up, it doesn't work...exactly. If I switch the TV input to 'Component', I can get the audio of whatever is running on the Macbook, like from a Netflix movie. As for video, the only thing I get is when I switch the TV input to 'HDMI'. Then, all I get is the generic Apple purple sky. The only things that I can get in the screen of the TV that also shows up on the Macbook are when I open up things like the System Preferences menu. No browsers or other apps.
Can somebody please help me further?
Thanks
PS - yes - I am a newbie to Macs, being a PC person since '96.

Mac Mini: DVI+TOSlink- HDMI Adapter, still fiction?

Hello
I've been studying for a while the best solution for connecting my early 2009 Mac Mini to my LCD TV and Blu-Ray 5.1 System. I didn't took long to figure out the "Mini-DVI->HDMI Adaptor for video" and "Mini-TOS->TOSlink for audio" scenario. The problem is that I'm short on optical inputs. After thinking it through for a while, it dawned upon me that a "DVI+TOSlink->HDMI" adapter would crack this one. This adapter would take the DVI video and the TOSlink audio signals from the Mac Mini and composite them into one single HDMI stream. It seemed far fetched that such an adapter would even exist, but I decided to give it a go.
At first, after some initial research, I only found adapters like the following:
http://www.amazon.com/Audio-SPDIF-Toslink-Converter-Adapter/dp/B0015YYOQQ/ref=sr11?ie=UTF8&s=electronics&qid=1258995241&sr=8-1
http://www.amazon.com/Audio-Toslink-HDMI-Converter-Adapter/dp/B002N8PVTM/ref=sr14?ie=UTF8&s=electronics&qid=1258995241&sr=8-4.
Although they do convert the DVI signal to HDMI, the same can't be said in regard to the TOSlink audio signal. The audio part is not encoded into the HDMI stream, getting out through the same optical port it got in.
I was about to let it go when I found this adapter:
http://www.monoprice.com/products/product.asp?cid=101&cp_id=10114&cs_id=1011405&pid=5369&seq=1&format=4#feedback
The are a few customer reviews that specifically state it works flawlessly with the Mac Mini.
The questions are: has anyone tried one of these? Does it really works? It it really possible to composite an HDMI stream from DVI+TOSlink inputs? If so, will it be any quality loss associated to the conversion process?
Thanks in advance

Welcome to the Apple Discussions!
There is not really much converting going on with regard to DVI (D) to HDMI. I use the mini-DVI to DVI (D) adapter that came with my Mac mini and a Belkin cable that is DVI (D) on one end and HDMI on the other. The signals are compatible. But as you say I run a separate audio cable from the mini to my HDTV. That is the real conversion that is taking place in the "black box" devices to which you are linking; adding the audio to the video.
There is another route that skips the video output from the mini altogether, but it is a bit more pricey, USB. I know of two USB to HDMI "black boxes" that give you both audio and video in the HDMI stream.

Mini dvi to hdmi adaptor vs. mini dvi to dvi adaptor

Do the mini dvi to hdmi adaptor works? I notice a lot of them for sell on ebay, but none at apple store. Does apple not recommend this setup? Most of the forums address the mini dvi to dvi adaptor to dvi to hdmi cable set up. I can not find anything that clearly says you can use the mini dvi to hdmi adaptor and just connect a regular hdmi cable to get video from a macbook to tv.
BTW My LG tv model 42PC3D (link to manuel below) says that the HDMI cable supports computer connection.
http://us.lgservice.com/index_b2c.jsp

There are reports here that non Apple mini DVI-->whatever cables don't work correctly connect to a MB. That said, if the cable is cheap enough, give it a shot. I just looked at the mini DVI-->HDMI cables on eBay and they all look "short" and for most installation, will require a longer HDMI-->HDMI cable.
So, unless the price of a DVI-->HDMI cable is a lot more than an HDMI-->HDMI cable, why not go with the standard Apple mini DVI-->HDMI cable? However, if you already have the latter, I can understand why you might not want to buy the former cable.

Mini Dvi to HDMI to LCD in windows 7

I have a macbook (2008, 2.1 C2D, intel 965 GMA) and i use a mini dvi - hdmi adapter to connect to my sanyo lcd, which is basically a plug and play process under snow leopard. However, say i want to use windows 7 to play a game through the tv - fail. The computer, under the same conditions as before, with updated drivers and liberal application of swearing, fails to recognize the tv. Any help?

I have a MacMini that is a intel core solo and has the DVI port not the mini-DVI.
I was able to load win7 but only after connecting the MacMini to an LCD monitor via DVI-to-VGA converter that came with my mac mini.
I am running snow leopard on the mac side and the video works great in 1080p via DVI cable direct to my DLP tv. but when I loaded win7 the tv couldn't display the video feed. The tv read "not compatible data". The DLP tv has a VGA input and win7 is running fine on it.
I am looking for a way to enable the video card to give the same quality on the win7 side as the OS X side, so that I can go back to the DVI cable and the 1080p I was getting in snow leopard.

Using Mini Dvi port as input

Okay I need your help guys. I have a 2008 Imac, which means it uses Mini-DVI output.
what i want to know is, can i use this as an input for my PS3 using a Mini-DVI to HDMI adapter so i can play PS3 on my imac display?
http://www.amazon.co.uk/Apple-Mini-DVI-HDMI-female-Adapter/dp/B004RZ2YXU/ref=sr_ 1_4?s=electronics&ie=UTF8&qid=1311369816&sr=1-4
I also realise that Mini-DVI doesn't transmit sound so i will probably need a 3.5mm audio jack to red and yellow composite cable.
http://www.amazon.co.uk/3-5mm-Stereo-Jack-RCA-Phono/dp/B001711TW4
Is this possible? i know it can be done easy on the 2010 imacs
Also i am not running Snow Leopard so will the F2 thing still work?

No, it can't. Only the Mini DisplayPort and Thunderbolt ports on the newer iMacs support input.

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
