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

OS X 10.8.5 mac mini hdmi audio output issue

I am running a 2012 Mac Mini with OS X 10.8.5 and my Mac is set for audio and video output via HDMI to my AV receiver / TV. I have recently noticed that HDMI audio output ceases to function once the computer goes to sleep. A full computer restart is required to resolve the issue which is an inconvenience to say the least.
Or is anyone aware of a simple fix?
All my software is up to date, the HDMI lead and connection works fine for video and audio works fine after a restart so it must surely be a software error. Worked fine until the latest OS X update...
Grateful for any help!

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?

2010 mac mini hdmi sound output

Hi,
i have following audio setup via hdmi of my mac mini:
mac mini -> yamaha rx-v 665 -> philips tv
If only the receiver is turned on i have it as display and hdmi audio output device with 8-ch sound output. But as soon as i turn on my tv, my mac mini switches the sound output to my tv with only 2-ch sound output.
Anyone an idea how to prevent switching my mac mini to the tv sound output?
thx

I am trying to get my Mac Mini (2010) to use the speakers I have connected for my Samsung 40" TV through my Yamaha receiver as well. I connected to the TV to my Mini via HDMI thinking it would take care of video AND audio, but I cannot get the audio to function. Do I need to connect from the headset port to my receiver? If so, into which port?
My dream of making the mini and TV combo is taking a hit.

Connecting my Mac Mini DVI video output to Dell W3706MC LCD TV VGA Input

I tried connecting my mac mini to the Dell W3706MC LCD TV VGA input but it wanted me to change the resolution of the mac to 1360 x 768 at 60 Hz. I did that but it still would not display the video. I tried my PC laptop and that worked fine with different resolutions. So I know that there is nothing wrong with the TV. Did anyone experience this same problem?
Any help would be great.
Thanks,
Karl

I'm confused about your comment "it wanted me to change the resolution of the mac to 1360 x 768 at 60 Hz." I presume the way this was communicated was through a dialog box, correct? But if you could see a dialog box, that means you had a working screen at one point, correct? Why don't you just run at that resolution?

HT4534 Mac Mini HD Video Conferencing

I am considering purchase of a mac-mini for video conferencing. This article (http://support.apple.com/kb/HT4534?viewlocale=en_US) refers to "built in camera". Of course, the mac-mini has no built in camera. I would be using my HDTV for a monitor. Can I use the Logitech c910 & the mini for HD Facetime?

I also have a mac mini and am using the Logitech C920. At the beggining, I had issues with its built in mics not working with FaceTime, but I found a solution for the problem and now all the programs that interface with the camera work great (FT, Skype, iMovie, etc). If you do buy the C920 run into the same issue that I had with the mic not working, here is the quick solution for the problem:
Cause of Problem: The Logitech C920 camera/mic operates on a 2ch-16bit integer. You can verify this by opening "finder + Utilities + Audio MIDI Setup" and then select the HD Pro Webcam C920 and look at the "Input" Default values.
The Mac Mini's "Built-In Output" and "Buiilt-In Input" formats were set for 2ch-24 bit integer. Therefore, the default input and output were out of sync with the C920 default format.
Solution: Change the Mac Mini's default Output to "2ch-16 bit integer". You don't need to change the default Input but it doesn't hurt to do so. Once you do this, the camera and it's built in mics work on facetime and all other video chat applications.

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.

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.

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.

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!

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) 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.

TS4113 Mac mini looses audio output through HDMI after being in 'sleep mode'

Since a month or so, my Mac mini is unable to send audio through HDMI output after being in 'sleep mode'.
Recently this was no problem, but now I cannot hear anything after unsleeping (unless I reboot fully).
Please help.

This is not just a Mac Mini problem. I've found comments from people with all kinds of Mac, with any kind of external sound device, who all have this same issue.
The common factor is Mountain Lion.
Apparently there is a new build (12F42) which is supposed to fix this.
http://www.gadgetguide4u.com/new-os-x-1085-build-number-12f42.html
Apple released it to their employees on the 25th Sept.
Here's hoping that build is available for the rest of us soon ...
