Problem switcing Mac Mini HDMI via an Onkyo 606 Receiver

I'm having problems when attempting to switch my Mac Mini HDMI via my Onkyo Receiver. Connecting via a DVI to HDMI converter. Works fine when connected directly to the TV.
When connected via the Onkyo, I get the Apple logo at the begining of the boot-up process, but when the screen would ordinarily switch to my desktop background, the screen goes blank.
Any suggestions?
John.

Do you have a second computer at your disposal? In cases like this, the best debugging method is to use a second computer and create a screen sharing setup under OS X Leopard, or a VNC set up if the second computer is not a Mac running Leopard. That way you will be able to see exactly what the mini is doing, even though the TV is blank.
Probably, in the end, you are going to need something like Gefen's DVI Detective to get HDMI switching to work the way you want it to.

Strange problem with mac mini hdmi, denon avr 3310 and itunes

Hello,
I just bought the new mac mini with HDMI. It is connected via HDMI to my receiver Denon AVR 3310. The receiver shows that it has "multi channel in" on the display.
I made all the configurations so that i can watch dvd an the mac mini. When i play a movie with Dolby Digital the receiver does show that on the display and playback is possible without any problems. I hear sound on all my 5.1 speakers.
The big problem is with iTunes. When I want to watch rented series, for example Dr. House, only 2 speakers of my 5.1 are used. And when I change to surround in iTunes I can only hear static noise.
What is the problem? Did I make a wrong configuration or is something wrong with iTunes?
Thanks in advance

Great news! My Mac mini is sending true 5.1 to my reciever through the HDMI cable! Okay so here's my list of gear.
MAC MINI 2011 2.5 i5 8gb ram
Using a quality audioquest hdmi I have connected my Mac mini to my Denon 1712 Reciever. I have connected this hdmi cable into hdmi port entitled game 2. I have connect my reciever to my tv with a monster 1000 hdx thx certified hdmi cable. It has a transmission sped of 17 gb or so...meaning it can handle transmitting 3d...if only I had a 3d tv.
Okay so that's the gear. Now onto the changes in audio midi. Open audio midi and Simply change it to 48000 hz and to 2 channel 16 bit integer. That's all I did and now it works. Before I had it set to 8 channel 24 bit and when I pulled up my surround sound options I could pretty much only get multi channel stereo. Now I can get several Dolby choices.
The voices are coming out of the center speaker and all the action is coming out of the other speakers....so in other words 5.1 surround sound has been achieved on my Mac mini 2011 which has Lion on it.
I have tested this with iTunes and Netflix. Both are in 5.1 and sound great. In iTunes I have tested both music and digital copies of movies. Both worked flawlessly.
Rejoice Mac mini owners 5.1 surround is now possible over your Mac mini 2011 edition with just an hdmi cable to your reciever. You can throw away that toslink cable becuase now you don't need it!
I hope this works for you. Remember not all hdmi cables and the same holds true for your reciever. If it does not work consider getting either audioquest or monster....everything else is junk.

2011 Mac Mini HDMI only 2Ch Stereo

Wow is this frustrating. I've had my Mac Mini for about a week, and for the life of me, cannot get surround sound working via HDMI. I've read so many posts about people with this problem but I can't find a definitive answer for a fix. All I want is for the Mac Mini to passthrough the audio so that my Pioneer Receiver can handle all of the Dolby stuff.
Setup is simple -
Mac Mini ------> HDMI -------> Pioneer VSX-1020 Receiver --------> Samsung 55" LED
Inside of the Midi Audio options, it shows my receiver as the audio device, and I have all of the options for 2ch, 8ch, etc. I also selected Dolby 5.1. I can only get PCM or Stereo to display on my receiver while ticking through these channel options, while I would expect Dolby to display if it is receiving a Dolby signal. Also, when I do the test tones in the Configure Speakers area, I get the correct test tones from all channels. BUT.........
No matter what I play whether it be iTunes, VLC, etc, I am only getting 2 channel sound and my subwoofer.
Can anybody help?? This seems like such a simple task yet it has me pulling my hair out.

ive had my 1021 for about 2 months and i think its great. Do you like yours?
i have 5.1 using optical cable to one of the optical in ports on the 1021. But you will need an optical-to-miniOptical adapter tip to use in the mini.
then make sure that any app through which you want 5.1 has that specified in its prefs. (like VLC)
VLC always has the option ' out through system', and if the system is optical out, then 5.1 will pass.

Mac Mini HDMI - Stuck CD

Hello,
I have a CD stuck in my new Mac Mini HDMI.
* It does not appear in the Finder as a CD.
* Disk Utility shows the CD drive itself, but all options for eject, format, etc are all greyed out.
* Booting with the mouse button down does not work (I have a bluetooth keyboard; however, I selected to stop using it and connected a wired keyboard)
* Booting with C down does not work
* Booting with Option down until getting to the firmware boot disk selection menu, then pressing / holding the eject button does not work
* I used the Terminal command "drutil eject", the drive makes the eject noise, but nothing comes out
* Tried System/Library/CoreServices/Menu Extras/ double clicking Eject.menu - the menu only has a greyed out drive listed
I think that's everything I've tried. Please let me know if there's anything else I can try.
Thanks for all your help!

I figured out the 'problem'
Let me pre-face it by saying, my wife originally emailed me at work talking about this disc she couldn't get out.
Flash forward to now. I was fishing around with my work badge (thin hard plastic) and I couldn't feel anything that felt like the edge of a disc. So, after getting up the nerve I took a blank DVD, and slowly let the drive catch it and pull it in. Loaded up just fine.
I guess the "Stuck CD" must have evaporated
Good new is, I now know every single way to get the disc out should this happen to me for real (short of completely disassembling the Mac Mini). For now, all I can do is laugh (quietly so my wife doesn't hear).
Thanks for helping out Boece!

Hi Gerard,
Are you certain there's no traces of MacKeeper left?
I have no idea how they can get away with advertising MacKeeper at all.
You really really need to uninstall it, but maybe not using their uninstaller.
Klaus1's great post on MacKeeper...

Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
Reboot & see if Flash Installer works.

Mac Mini HDMI Output Problem w/ LG L246WP

NOTE: This appears to be unrelated to the "screen flickering" that has been noted previously.
I'm using a fresh new Mac Mini 2012 with an LG L246WP LCD monitor. The monitor has HDMI, VGA and Component video inputs.
When I attach the monitor to the Mini DisplayPort output, using a Mini DisplayPort to DVI adapter connected to a DVI to HDMI cable, the display functions properly at all resolutions - including the native 1920 x 1200 resolution that I use it at normally. All resolutions are clearly displayed in the "Displays" System Preferences pane. The display looks perfect, functions properly.
When I attach the monitor to the HDMI port using an HDMI cable, the display does not fucntion properly. The display is shifted about 80-100 pixels to the left and about 20 pixels up, creating black bars on the bottom and right sides. Because of this, a large portion of the display is not visible including the menu bar and most of the left side. Additionally, the settings are reduced to "Best for Display" or "Scaled", with resolution options under "Scaled".
This is not acceptable. I had planned on simply using the Mini DisplayPort output as a workaround, since I already have the DVI adapter from an old setup, but I need to use Thunderbolt to access external hard drives for rapid data transfer. One of my Thunderbolt accessories does not have two ports, so I can't simply add the Mini DisplayPort adapter to a chain. The HDMI port needs to function properly with my monitor.
It's important to note that this monitor has functioned properly with many other comptuers running OS X, Windows and various Linux flavors and it hasn't ever done this before. I've tried several different HDMI cables, ruling that out as a problem. I've tried the HDMI to DVI adapter that ships with the Mac Mini 2012 along with two different DVI to HDMI adapters, ruling that out as a problem. I tried attaching several HDMI devices (game consoles, DVD players, etc) and they all function properly, ruling out an HDMI issue as a problem. The monitor functions properly when attached through the Mini DisplayPort to DVI adapter, so it's not a problem with the monitor. I've reset the PRAM already and the installation of OS X 10.8.1 is stock with no modifications or migrated data. I've tried the suggestions on the HDMI FAQ (although there's no "underscan" option available in Displays)
I tried to call AppleCare and after describing the problem I got disconnected with no callback. I started another ticket, described the problem, discussed the previous disconnection, was assured that I'd be called back if disconnected, and haven't heard back in two hours. So I started to dig into the problem in earnest.
This gets pretty technical.
After substantial research, it appears that this issue is related to the EDID that the monitor sends to the computer and, crucially, the way that the driver responds to it. For some reason, the HDMI port is recognizing the monitor as a CEA device instead of a monitor. As a result, it's restricting the monitor's available resolution to the native resolution that the CEA 681 Series Extension describes ("Best for Display") and all other resolutions (including 1920 x 1200) are only available as "scaled". For some reason that I can't discern, all resolutions (even the 1080i and 1080p options) have similar deformities.
I've attempted to fix this by placing an appropriate override file in /System/Library/Displays/Overrides with an edied EDID removing the CEA-enable flag from byte 127 but, even after a reboot, the OS still insists that it's a CEA device and it won't allow me to force it to recognize the monitor as a 1920 x 1200 LCD Monitor.
How did I come to this conclusion and develop the fix? A nearly identical problem description showed up on the following website, with details on how this user fixed the issue:
http://byuu.org/articles/computing/edid
They used a convoluted process that involved dismantling the monitor and flashing the EDID on the monitor itself. It fixed their problem. I'd prefer not to go through that process just because one computer has a problem with it. Frankly, I'd prefer if the new Mac Mini performed properly in the first place.
TL;DR: The Mac Mini 2012 doesn't work right with the LG L246WP through the HDMI output. Everything else works fine with it. This is very uncool. It's most likely to be an issue with the driver for the Intel HD Graphics 4000 GPU that are bundled with OS X 10.8.1. The Mac Mini 2012 won't update to 10.8.2 (yet), so I can't test it.
Anyone have any other ideas? Anyone else using a Mac Mini 2012 (or 2011) with an LG L246WP monitor? Anything simple I've missed?

Problem Resolved. But it was complicated. And a huge pain in the rear.
TL;DR: I flashed the EDID as described here. This is not recommended for the weary. Ideally, Apple should release an update OS X that will include the updated Intel HD Graphics 4000 drivers that utilize the CEA flag properly.
Here's the detailed version. As mentioned above, this isn't recommended for the weary. An improper (or interrupted) EDID flash can have seriously unpredictable effects on a monitor's performance.
Step 1: Get a Windows PC set up with a floppy drive and find a floppy disk. Use this system to format the floppy as a MS-DOS Boot Disk and copy over the "ddcw" program described at the aformentioned link.
This took awhile, but I was able to cobble together a temporary frankensystem with parts I had laying around. In installed XP and formatted the disk with XP's format tool.
Step 2: Grab EDID data from the monitor, modify it to disable CEA mode at bit 127 and make sure bit 128, the checksum, is appropriate.
This also took awhile. Several graphics cards I tried could not read or write EDID data. I ended up swapping AGP cards in my frankenstein box until I found one that worked - a generic GeForce4 4200.
Once the EDID data was written to the floppy, I edited the text file containing the EDID data to change the last two hex octets from "01 33" to "00 34" (00, to disable bit 127, and 34 is 33 + 1, which satisfies the checksum) and formatted the text file to match the sample included in the EDID_Write.zip file. Your mileage may vary - make sure the checks.
Step 3: Write EDID data to the monitor.
The link above mentioned three options: Easy (monitor's EDID is unprotected - write away!), Hard (monitor's EDID is protected - use service mode to attempt a fix), and Very Hard (monitor's EDID is protected, hardware modification is required).
Luckily my LG246WP simply needed to be put into service mode as described at the link above (menu + power) and once started up in service mode, I simply enabled "Aging Mode" (whatever that means) and attempted a DDCW write of the updated data.
Step 4: Profit!
After doing this, I powered off the monitor and powered it back on with the Mac Mini attached. The display functions PERFECTLY with HDMI out, just as it does using the Mini DisplayPort to DVI adapter.

Mac Mini, HDMI option problem

On my Mac Mini,In sound output options I cant select HDMI for my TV since upgrading to Mountain Lion

I was able to get sound form my VIZIO GL47L after a reboot when using it as the only display. However, audio does not work for me when running dual displays.
I am thinking I will most likely break down & buy an AppleTV and Airplay mirror it.

Can't get MAC MINI HDMI to consistently display on TV monitor

My new MAC mini is connected to a new HD Samsung TV. Initially had problem showing HD movies because I had Mini connected via VGA. Purchased appropriate connection for HDMI and HD movies show great, for a while. Appears that sometimes zhen the mini sleeps, monitor doesn't see mini with HDMI connection. When I switch back to VGA, the monitor once again sees the mini. Recently HDMI was working great until I downloaded updated software, and now once again monitor doesn't see HDMI, only sees moni when I reconnect via VGA. I've checked all connections many times and can't find the issue. Looking for any assistance.
THANKS

Update: Got the HDMI working again. Since I couldn't see mini mac with HDMI, hooked up VGA and restarted. While mac mini was restarting, changed connection to HDMI and low and behold, the monitor saw the mini in HDMI. Don't know if that's the optimum way.... but it worked.

2010 Mac Mini HDMI 1080p output to Samsung B750

Hi all,
I just got the new Mac Mini. My primary reason for getting it was because it had an HDMI output. I've now hooked it up to my Samsung LCD via HDMI to HDMI and it automatically detected it as 1080p. The image was pristine!
However, the issue I am experiencing is quite irksome and basically defeats the purpose of having it as a HTPC. There is a severe delay between the movement of my mouse and the actual display of it on the screen. There is also audio/video syncing problems.
This problem does not occur when I have it hooked up to my original monitor via miniDP, so I'm assuming it must be a TV or Mac display issue when outputting at 1080p. Is there a specific setting that I must do to either the Mac or the TV?

I just bought a mac mini(2010) and had the same issue as coaster - mini to samsung P2270HD via HDMI gives a very bad picture quality. Took the mini back to the store and they reproduced the problem on the same monitor. Then the guy took a dvi cable and via HDMI-DVI adaptor connected it to the same monitor but on DVI input. Picture quality was fantastic.
Now why did that happen? Same HDMI port but different input to Monitor

Brand New Mac Mini HDMI Sync Issues

I just purchased (as in 3/29/13) a late 2012 2.5GHz 500GB hard drive 4GB RAM Intel Dual Core i5 Mac Mini MD387LL/A. It is connected to a 27" Samsung B350 S27B350H monitor via HDMI to HDMI.
I was excited to set it up. I was downloading the 10.8.3 update as I had read about the flickering problems. In the middle of the download the computer went to sleep. Upon waking the monitor flickered badly then went black. Like it was not receiving a signal.
I powered the monitor down, and turned it back on. It had a display for about two seconds then went black again. I tried this several times with the same result each time.
Finally the update to 10.8.3 was complete and....the problem persisted.
I decided to see if it was the cable or the monitor. I connected the monitor directly to my Xbox with a different HDMI cable and it worked perfectly. So I switched to the original HDMI cable I used with the Mac Mini, again it was perfect!
Upon reconnecting the monitor to the Mac Mini it was working again...for about an hour now the problem is back.
I am completely frustrated and disappointed.
Suggestions?
Or do I just return the Mac Mini for a different one?

Were you able to get your display working? I have an LG 27" at home connected to a Mid 2012 (June) MacBook Air 13" that has absolutely no issues. However, I just obtained the same Samsung monitor you have and appear to be having the same issue.
The only solution that I have found is to unplug the power from the back of the monitor or at the power supply each time my computer either wakes from sleep, screensaver, or a display that is powered off. This seems to be true via the following connections:
1. HDMI to DVI thunderbolt adapter
2. HDMI to Thunderbolt adapter
The display powers on with a slight flicker and then will immediately stop displaying the image on screen. What's especially strange here is the MacBook Air still believes the display is connected -- my login screen or active apps that are displayed on the external monitor do not move to the MacBook Air display as if it's no longer connected.
I hope someone has a solution to this issue! Thanks!

Screen corrupt 2010 Mac Mini HDMI (Static/Snow/White Noise)

I've just upgraded my 2010 mac mini to Lion, this is connected to a projector via HDMI to a Denon amp. Before the upgrade there were no issues the picture was completely clear and was usable in all resolutions.
Now that lion has installed the display is not usable, all I can see is 99% static and a corrupt row at the top of the screen where the menu bar can be just about made out.
Nothing has changed to the setup other than installing Lion, if I use screen sharing I can see the desktop happily, the OS is fully responsive.
I haven't yet tried to connect it to another monitor as I don't have a spare, I'll attempt this over the weekend, has anyone else experienced this issue?

I've got a similar issue and seems like a few others also have problems as well
https://discussions.apple.com/thread/3196192?tstart=0
My Mac Mini wont boot to HDMI and Screen Sharing wont link in since Lion upgrade......
A makeshift solution is unplugging the HDMI during boot up, give it 30sec's - 1min...plug it back it and then it should come up.... works for me for now.....
hopefully someone has a more permanent solution or mac solves the issue ASAP....
Cheers

Mac Mini HDMI port broken?

I have a Mac Mini Mid 2010 that has been acting as a media center / small file server. It's been running Plex, FTP and VPN services. It has been hooked up to a Pioneer VSX-921 receiver with a HDMI cable since day one, and it's been working beautiful.
Then yesterday evening, switching to the input of the Mac Mini, I got "no signal". I double checked all connections, made sure the computer was actually running using remote desktop. Everything seems fine. I switched the HDMI cable with an Apple TV i have in my bench as well, the cable is fine.
So I went looking for problems on the Mac Mini. Under displays, I no longer have any HDMI option for output. Same with audio. It's as if the computer simply doesn't have an HDMI port any more. I've tried the classics PRAM, NRAM and SMC. I've checked for updates. Nothing so far.
I'm slowly coming to realise maybe my motherboard has gone bust. As the computer is over two years old, it's well beyond Apple warranty, and it's a month over the extra year long european consumer law, so I'm not expecting to get much help from Apple. Especially since I've installed my own SSD in the Mac Mini. That was done in the first few weeks, and everything has been fine for two years since then, so I do not believe that matters. But they will.
So, before I do anything else, like consider reinstalling the computer, getting a new motherboard, throwing it out or buying a new one. Is there anything else I should be checking before proceeding?

Further testing shows the Mini DisplayPort doesn't work either. It shows an extremely grainy (in a digital way) white with the Apple logo on boot, but then stops sending signal. So basically the only way for me to access the computer is via remote desktop, which also makes it impossible for me to re-install the computer. Worste case, I'm locking myself out of my own computer.
I'm quite convinced the motherboard is to blame at this point. Weird how it can just break like that. Nothing was changed, no cables touched, the computer hasn't moved for 24 months. Damnit.

Mac Mini (HDMI) Bootcamp Windows 7; no video after wake

I just installed Windows 7 on a bootcamp partition on a new mac mini with the HDMI out. Everything was fine until I left the machine for a while and it went to sleep. After waking it up I no longer get any video output, either via the HDMI or MiniDisplay port. I don't really want to turn off the sleep function of windows 7. Any hints as to how I could make this stop?

I tried a suggestion from another thread and found that if I switched the hdmi cable to another input on my Sony TV video was restored, then if I switch it back to the original input it works. It may be a problem with the hdmi hand shaking between the mini and the TV - because unplugging and replugging to the same port didn't work. I'll see how repeatable this recovery work around is.

Mac mini hdmi video output blurry

I have an Aug 2011 mac mini plugged into an AV receiver en route to a sony bravia 32" and the resolution is pretty bad, especially text and photos. PS3 and HD cable box output look great. I've tried working with the picture resolution on the tv but that does little to help the fuzzy mac mini video output. I have an earlier vintage mac mini that used a monitor cable to the tv and the resolution was fine -- do I have to go back to that? It seems from the message boards that windows 7 on mac mini works fine and looks great but that OSX is failing to deliver a sharp image. Suggestions? Or is there some software fix available?

I just bought a mac mini(2010) and had the same issue as coaster - mini to samsung P2270HD via HDMI gives a very bad picture quality. Took the mini back to the store and they reproduced the problem on the same monitor. Then the guy took a dvi cable and via HDMI-DVI adaptor connected it to the same monitor but on DVI input. Picture quality was fantastic.
Now why did that happen? Same HDMI port but different input to Monitor
