P7NGM simultaneous DVI + HDMI?

A small question about the P7NGM mainboard: does it support simultaneous output on both the DVI and HDMI ports? Or does it only work as DVI + VGA / HDMI + VGA?
The product description and the manual didn't provide the answer... Hopefully someone with this mainboard knows

umm i hit F7 on my macbook
that did the job..

Macbook Pro 2011 DVI HDMI out does not work with TV when the power cable is connected

My Macbook Pro (Early 2011) DVI HDMI out does not work with TV when the power cable is connected. If get the blue screen and then can use the macbook but nothing is displayed on the TV. If i go into display I can see that there are two screens but nothing displayed on the TV. If i take the power cable out at this point the TV shows the second desktop as expected. If i then reconnect the cable, the screen flickers, as though it is being affected by the power cable, and the screen goes blank on the TV. Only if i remove the DVI cable do i get the blue screen again. If i remove the power cable and reconnect it will do it every single time, so i cannot see it being a TV issue or a minor glitch.
I have had this working previously but at the minute it seems to not be playing ball....any thoughts
Thanks

Any ideas?

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.

HDMI doesn't work, but MDP- DVI- HDMI works

Hello!
I just got my new Mac Mini and tried to connect it to my TV (a Samsung LE22S8) over HDMI, but this doesn't work since the TV reports "unsupported resolution" (it's the TV's native resolution of 1680x1050, where I also checked all frequencies using an external program and they are as written in the manual of the TV).
However when I connect the TV over a Mini Display Port to DVI adapter, and then use a DVI to HDMI adapter (so that the TV is still using the HDMI input) it works fine.
So what's the difference between MDP->DVI->HDMI and HDMI->HDMI (all resolution and pixel frequency settings are identical)? What can I do to get the HDMI->HDMI solution working?

It also appears that there is no conversion when HDMI-video is extracted from DVI, only that the pins are shuffled.
If direct DVI works on that port, then HDMI-video with an adapter should work as well. As I mentioned above, VGA is present on DVI-I ports on a separate set of pins, and VGA working or VGA not working has no bearing on your problem.
If a Mini DisplayPort is involved, the most common issue is that the Mini DisplayPort connector is not inserted firmly enough. It has a lot of pins and you have to press hard to seat it.
Other possibilities are that the resolution you selected is beyond the capability of the display device, or that the adapter is bad.
Is this the stock display card, or one you added later, and what model?

Macbook mini-DVI - DVI - HDMI not working with My 32" Vizio

Okay so my Macbook mini-DVI - DVI - HDMI is not working with My 32" Vizio. I've connected an 18 pin plus one slot DVI to HDMI cable to my 32" Vizio HDTV, this cable is connected to my macbook via a Mini-DVI to DVI cable, this one has 24 pins plus one slot on the DVI side. My Vizio display is blue, no signal, it reads. I'm wondering if the reason it's not picking up the display is the lack of pins on the DVI to HDMI or because I dont have any display options aside from screen size and color on my display menu. BTW I hit the detect display button and nothing happened.... I know I just wrote alot here but hopefully someone will read it and come to the rescue. thanks

Oops, I guess all I had to do was restart my macbook. I feel like an idiot.....all is well.

Connecting MacBook to Sony Bravia via DVI-HDMI!

Hi I am having major issues with my Macbook connecting to my Sony Bravia KDL-32V4000 I now have 2 different DVI-HDMI leads as well as the Apple Mini-DVI-DVI and still have absolutely no luck.
The Macbook is picking up the Television absolutely no bother at all but there is just nothing at all coming up on the Television its self it doesn't even recognise that I have the computer in the HDMI slot nothing at all just blank!
Any help would be greatly appreciated as it will save me buying more and more cables if this fails to work will have to go with the DVI-VGA I guess would rather fix this though!
Thanks!

I bought a mini-DVI to HDMI and an HDMI to HDMI cable. Once I went into settings for the display, I found that the TV was acting as a second monitor and that it was off to the right of the macbooks own screen. Thus if i moved the mouse to the right it could control the second monitor. You are able to move the screens so that they have the same data on each or use them as two screen with different info on each. Each screen is clearly visible in Spaces and it works a treat.
It is also possible to use the TV as the only screen. The way to do this is to connect up and close the lid on the mac. Once the light on the front starts blinking you can wake it up by using your mighty mouse or external keyboard. once awake, assuming you have chosen the correct HDMI connection from the TV the TV will act as the only monitor at full resolution.
The problem I have, is that I have not been able to get the sound to work. I have used the earphone socket and connected that to external speakers as I cannot seem to get the analogue signal on the TV on anything but an AV channel (not an HDMI channel). Thus the sound works on one channel and the image on another. My TV is a Sony KDL40w5710 - thus if anyone know the solution to getting the sound running through an HDMI channel on my TV it would be appreciated if you could contribute.
Cheers

Mac Mini on Toshiba Regza Z3030 42" via DVI- HDMI

Hello,
I'm trying to connect a Core2Duo Mac Mini (running 10.4.11) to a 42" Toshiba Regza Z3030 Full-HD TV via a DVI-HDMI cable. The TV does 1920x1080 (both i and p), but when I select 1920x1080 (interlaced) from the display resolution menu in System Preferences, I get a black frame around the image that is twice as large on the right side of the picture than it is on the left or top/bottom sides (so even if I enable overscan, the picture is not acceptable, as it's missing a strip of the desktop on the left, top and bottom sides then).
I'm running the TV on "Exact Scan" mode, which (according to the manual), should display a 1080 signal exactly the way it is received from the source, no stretching or scaling at all.
Incidentally, the grey screen with the Apple logo and the spinning progress indicator fills the screen completely in 1080i, but as soon as the login panel comes up, the picture gets the black bars, so I think it's a MacOS X issue. Can I somehow tell the Mac not to switch the display settings after the booting process is finished, as the image during the boot process is perfect?
Any hints on what I could try?
Thanks in advance,
Georg

Ok, I decided to take some more time and googled for how SwitchResX actually works and what all the settings in the "custom resolution" view mean. I stumbled across a very useful tutorial in this forum thread: http://www.avsforum.com/avs-vb/showthread.php?t=751713
Following these instructions (basically, I just had to play with the "front porch" and "back porch" parameters until the image was perfectly centered), I ended up with a custom resolution in which the image is centered, but still has black bars around it.
Next, I simply turned on "Overscan" in the Display preferences while setting the TV's HDMI port input to "Exact Scan", meaning it will display the image exactly the way it comes over the HDMI port, without extra scaling.
With this combination, I now ended up with a picture that fills the whole screen and has (according to a test image) a "1 to 1" pixel mapping. Also, for some reason, this new resolution that I made myself rather than taking the values off the internet "sticks" between sleep and wake cycles as well!
For some reason, though, the TV only reported that it supports 50Hz vertical sync in 1080p when I used the "Export DDC" function in SwitchResX, even though according to the manual it also does 60Hz (and the default 1920x1080, 60Hz resolution from the Display preferences works as well). Therefore, I was only able to make my custom resolution for 50Hz, as I need the values from the DDC export as a starting point.
I only want to use this Mac Mini/TV combination as a media center for movies and music streaming via iTunes, so I guess it won't make any difference wether I'm running it at 50Hz or 60Hz?
Anyways, I hope this thread might help other people with the same TV who are having similar problems with their Mac Minis.

DVI-HDMI Adapter for hooking up a HDTV...Few problems...

I have a spare 32" Sharp HDTV with HDMI, so I placed this next to my Mac Pro and used a DVI-HDMI adapter. Here are the problems:
With my standard GeForce 7300 GT you cannot use both connectors, as they are too close together - so I could not even test to see whether both DVI outputs can work at the same time. So I have to disconnect my 23" cinema display. Now, the Macpro recognizes the TV - in the display preferences - but the resolutions are not good - the only one that works is 1280x720. Other resolutions listed, ie, 1344x756 and higher are listed as interlaced and all cause flicker. This means I do not see the OSX top menus.
I wish to be able to show clients samples of edited movie clips on a HDTV both in FCP and standalone QT. I doubt that appleTV is the answer, as this only works in iTunes - plus, my Mac is next to my TV anyway.
Any thoughts on making this work better? I am trying to not have to buy a new video card. Maybe the Black Magic Intensity card for HDMI output is the answer?

I can live with the lower resolution - the TV is actually 1366 x 768, but the most annoying is not being able to use both DVD connectors on the card at the same time - they are too close together, how stupid is that?
Ideally, I would like to see both the cinema display and the HDTV running at the same time - or least not having to manually switch over the adapter at the rear.
I see no way around this, unless I change video cards but for $250 I can get the Black Magic HDMI card which outputs DV via HDMI to HDMI.

DVI HDMI Poor picture quality, grainy / combing

Hi Guys,
Have just purchased a 26" Samsung LCD and have it connected to my G5 via a DVI-HDMI cable. However, full-screen playback on the monitor from FCP looks really poor- very grainy, with lots of combing (Note: the LCD autodetected a 50hz/1920x1080 interlace setting).
I know FCP has this setup as a CINEMA DISPLAY PREVIEW so its not really full-quality, but even still- it looks worse than when i was using a tv attached via S-Video!
Would anyone be kind enough to share what i might try to address the problem? i have already tried the obvious altering resolutions etc- but to no avail...it has me confused!
Many thanks,
Adam

I know FCP has this setup as a CINEMA DISPLAY PREVIEW so its not really full-quality
Yup...that's it. It isn't full quality, it is a lower resolution to ensure that no skipping of footage occurs (dropped frames).
even still- it looks worse than when i was using a tv attached via S-Video!
That was via firewire to a DV device, correct? Because that IS a proper FULL RES signal, so yes, it will look better. DVI out means that it is sending a COMPUTER signal, not a VIDEO signal...so the quality is worse.
Would anyone be kind enough to share what i might try to address the problem?
Yup...get a capture card. With a G5 your options are limited. NO Decklink Intensity with HDMI out...no Matrox MXO with HDMI out. The MXO will do DVI to a computer monitor and clean up the signal, but you can't convert that DVI to HDMI I don't think...messes up the signal. BUT, you could use the MXO and go COMPONENT to that monitor. That would be a good signal. Otherwise you are looking at Decklink HD cards or Kona LH...the Decklink might be comparable in price to the MXO.

DVI- HDMI discoloration on HDTV (as second monitor)

Hello all.
I have been having some issues when using my Philips CRT 30" 1080i HDTV as a second monitor via a DVI->HDMI cable. There seems to be a discoloration that occurs (my best guess being a "green" discoloration) that occurs in the top left corner of the screen. It is made all the more apparent when you then unplug, and a purple haze is left in the corner of the "blue" video input channel. (i imagine the green discoloration on the blue channel yields purple).
From what I can tell, this problem does not occur on any other video input (say, a Wii on the composite channel, or an XBOX on the component, etc).
I had heard rumblings that it could be, in order of bad to worst: a bad HDMI cable, a bad HDMI input on the television, or the television going bad period.
Wanted to know if any of you have had or heard of similar experiences. Need to decide soon if I'm going to had to just buy a new HDMI cable, or if I need to buy a new television/monitor for a job coming up.
Thanks in advance!

Problems like that are caused by stray magnetism that cause misalignment of the electron beams from landing on the proper phosphor color. The set itself has a demagnetizer, but sometimes the magnetism is too strong for the built-in demagnetizer to overcome. But calling in a TV repair person to do a demagnetization is, I'm afraid, a throw back to bygone days. But that's what your TV needs.

MacBook to HDTV via Mini-DVI to DVI-HDMI.

Okay guys, here's specific question about color calibration / resolution with DVI-HDMI output from my MacBook (or maybe any machine) to my LNT-4665. I've been trolling the forums for an answer. If you know of a thread, let me know.
The TV:
Samsung LNT-4665
It's a 46" with resolutions up to 1080p.
The MacBook:
MacBook C2D, 2GHz, 2 GB RAM, Leopard
Outputting through to a DVI-d to HDMI cable to my HDMI2 port on the Sammy.
The PC
PC with Windows XP, ATI X800 GTO graphics card. The PC is not available to me and was only used for this test.
Outputting through VGA to VGA input on the Sammy.
Images!
I took a bunch of photos in RAW format and converted them to .PNG. Alt-tabbing through New Windows gives you a better comparison.

Using Photoshop and a template I found online, I created this image. It is pixel perfect. The colors are exact RGB colors.

So, first of all, the resolution changes between DVI and VGA due to overscan(?). Maybe the Start Menu distorts the background image? I never fully understood how this works. Why would the picture look any different? How can I make it look the same? However, this is not my top priority.
The big issue, as you can see, are the colors. The color difference between VGA and DVI is laughable! The MacBook Display colors look better than the TVs. The DVI colors are totally washed out.
Am I outputting the wrong signal? Anyone know how to check that? Or.. fix it? I'd appreciate a crash course on any of this.
On the MacBook I played with the System Preferences>Displays>Color>Calibrate settings (I've created 5 different color profiles) to no avail.

Just to continue documenting my progress here.
From my TV's forum thread:

When you hook up the Macbook to the TV, it is acting as an extended desktop. I used to do this and wondered why I kept getting dropped frames and slowdown even on DVDs and DivX video. It did not fill the screen at 1080p even though Windows filled it.
To get it to fill up the entire screen, you have to close the Macbook ("clamshell mode"), wait until it goes to sleep, then plug an external USB keyboard or mouse in to wake it up. Then it will be working in 1080p mode and should fill up the entire LCD screen. Some people don't like this because they worry about the MB overheating.
I prefer to boot up in Windows XP on my Macbook. You can right-click on the desktop and it gives you an option to "Output to Digital Television." Then it blanks out the Macbook screen and outputs on the TV in full 1080p. The MB shell can stay open. High quality video usually runs better this way IMO. The Core Media Player is pretty good with most video files.
This is pretty strange/frustrating. I successfully booted the computer in clamshell mode but it still doesn't fill the screen. However, I rebooted the machine in clamshell and the BOOT SCREEN filled the screen! Then it reverts back to the little screen when the desktop opens up. Ugh!
Windows is my Plan B. Unfortunately, it requires backing up and reformatting.
Plus, why do I have to install Windows on my MacBook in order for this to work? Totally unacceptable. Why is this so difficult?! If Apple wants to get into the home theater market this MUST be worked out. I have no interest in buying an Apple TV if I already own a MacBook that SHOULD work fine. Why would I buy an Apple TV if it turns out I have to install WINDOWS on my MacBook for it to work?!
I hope you guys are listening.

Dvi hdmi no picture

My imac 21" is connected to a Sony Bravia LCD TV thru a dvi hdmi adapter; now the mac freezes on the big bang opening screen without any menu, even when the TV is off; previously the TV was detected but there was no picture on the TV screen. Should I do a PRAM and an SMC reboot ?

If you have a home theatre, the best way to do this is with a toslink cable (optical cable),if your systems
support it, with an adapter for the headphone plug on the mbp.
here are some suggestions that the forum had for me and others. good luck.
Hi Elaine,
The TV could be tricky to get audio out of if you are using a DVI to HDMI adaptor to connect to the TV. Is that what you're attempting to do? The problem with that is that the TV will be expecting audio on that HDMI cable, and it may not be possible to "map" another audio input to an HDMI input. Some TVs will have a DVI input, with an associated "DVI Audio-In" input that is "mapped" to the DVI picture, because DVI will only carry video.
You should be more successful if you connect the MBP to your home theatre directly. If the home theatre has a toslink input, you should connect the toslink cable between the MBP and the home theatre, and then set the home theatre to the appropriate input. You should get audio through that without problems.

Hi there, welcome to Apple Discussions!
It is most likely a video/audio pairing problem with the TV. The TV is expecting audio to come through the HDMI cable you've plugged in, but of course there is no audio through that connection. Depending on your TV, it may or may not be possible to map an analog audio source to a specific HDMI plug. That's what you'd need to do. If your TV has a DVI-in plug, it may be more friendly to the analog audio source because it won't expect audio on that video input.
Also, if you have a home theater receiver, you could plug the RCA into that and run that for sound.

Using a DVI HDMI cable with my Sharp Aquos LC-52D62U 1080p

Hello
I have a Mac Mini Intel proc with 4GB RAM (max RAM).
I'm trying to get it to work with my Sharp Aquos LC-52D62U 52" TV. The TV supports 1080p native, and the mini has had no issues connecting to this TV before. I just re-installed 10.6 (with all updates) and it does not want to connect.
I have a direct DVI > HDMI cable going from the Mini directly to the back of the TV. I tested other devices on that TV input and the TV works fine. I'm also convinced that the cable is fine as it worked before the re-install of the system.
I can see the Mac Mini using screen sharing on my Mac Pro, so I can make changes to the configuration over the network. The screen settings on the Mini are set to "1080p (Television)" just like they were when it all worked fine. But the TV screen is black. No picture at all.
What can I do about this?
Thanks,
-----------S

Hello Mac Mini world. I tried to connect my new Mac Mini to a 2 year old 32" Insignia Flat Screen HDTV through HDMI for hours however there was always part of the screen cut off even after adjusting both the resolution ratio on TV and Mini. After 3 calls to Insignia TV and Apple Support nobody had a definitive solution for me and was mainly told to live with it! One person from Applecare did half heartedly suggest trying a VGA connection instead in spite of lower quality. I went to the MAC store and they were confused as were the people at Best Buy but I reluctantly bought the MINI VIDEO PORT CABLE + VGA CABLE at Best Buy and to my surprise IT WORKED AND LOOKS PERFECT and automatically adjusts to fit any setting of computer resolution LIKE MAGIC. I have never posted but this seemed like good info as I read through a lot of blogs yesterday trying to resolve this issue. AGAIN THE SOLUTION IS TO TRY THE VGA CONNECTION. -chuck
