Did 10.9.2 break HDMI output on your Mac?

I have the mid-range, mid-2011 Mac mini (2.5 GHz Intel Core i5, 4 GB of 1333 MHz DDR3, and AMD Radeon HD 6630M graphics with 256 MB of dedicated GDDR5 memory), running OSX 10.9.2 and, at the time, the version of Server that was current prior to the most recent update. Two weeks ago, as I occasionally do, I packed it up and carried it and a semi-portable HDMI monitor off to my usual internet cafe. After hooking up the cables and starting it up I found that the monitor was just blank. After several restarts I had refined this assessment to the monitor goes suddenly blank partway through bootup. It was actually working long enough for me to see the apple in the center of the screen and the acitivity wheel gadget rotating below it, but at the end of that stage it goes blank as though it's suddenly lost the signal.
My Mac mini works fine with my 2010 Cinema Display, but no longer with HDMI. How about yours?

Yes, I take a Mac mini and a 19" HDMI monitor to a cafe, on occasion, although I didn't install 10.9.2 that way, and so only discovered the problem with HDMI display the next time that I did take it all to the cafe.
I don't have another computer with HDMI output with which to test the display, but it works properly with my mini through the first stage of bootup, so both the monitor and the display hardware are okay.
johnnyicon's comment that his setup initially worked with 10.9.2 makes me wonder whether that was the culprit. I have System Preferences => App Store => Automatically check for updates => Install system data files and security updates checked, so not everything that's installed shows up in Software Update.
Checking /Library/Receipts/InstallHistory.plist I see that there are several potential candidates, including several "Incompatible Kernel Extension Configuration Data", a couple of Server updates (I've since uninstalled Server for performance reasons), and several Google Voice and Video installers.
If 10.9.3 doesn't fix the problem, I'll take the mini (and monitor) to the local Apple Store
I suspect this problem was introduced as a side-effect of preparing for 2560 X 1440 resolution on 4K monitors over HDMI.

I can not get sound out of the HDMI output on my mac mini. happened before after unpluging headphone and had to change some hrz number.

I have had this problem before. I just cant remember how I fixed it. I am not getting any sound from the HDMI output. Everything is selected properly and volumes are set correctly. Last time I had to change a megahrz thing and thats where I am stumped.

Mac HD/Applications/Utiltiies/Audio MIDI Setup
441000 or 48000 Hz for Format

Can I use my late 2013 Macbook pro as a display for my xbox one. I am currently sick with the flu and I do not have a tv in my room. Is there anyway to use the hdmi port on my mac and connect it to the xbox one?

I am currently sick with the flu and in my room I dont have a tv. I tried plugging my xbox one's hdmi into the hdmi port on my macbook pro late 2013 retina display. I even tried connecting the hdmi cable to a hdmi mini display mort converter and that didnt work. How can I use my Macbook as a monitor to play game on

I would guess that the HDMI port on your mac is for output only - no input, and that's what your'e attempting to do when you attach the mac to your xbox. I looked in Mactracker and it lists the HDMI port as video output for both the 13" Retina MacBook Pro and the 15" Retina MacBook Pro (your post didn't say which one you have), so looks like that is the issue..

HDMI output not working since firmware upgrade

I would appreciate troubleshooting tips for getting the HDMI output to work. I just tried it recently for the first time in a long while, approximately 4 weeks after doing the firmware update to 2.2. When I did it before, plugging in the HDMI cable would automatically start output to my HD TV. Now that is no longer the case. Changing the HDMI output from "Auto" to "720p" does not make a difference either.
Otherwise, everything works well and I've been satisfied with my Creative 7 to date. I have installed several apps so it could be that there is a conflict and nothing related to the firmware upgrade.
Any troubleshooting suggestions would be appreciated.

Well I've received my refurbished device for about a week now. The HDMI still doesn't work either with Zii Video or a 3rd party app MoboPlayer. ?I am tempted to reinstall the firmware upgrade again. Is it ok to try this or is it only a one time attempt?
Perhaps this should be a separate thread but are any of the "Phone 2 SD" apps compatible with the Ziio 7? Whenever I use the "Move to SD card" option, there is still no program moved to the external SD card. ?I have a Ziio 7 with 6 GB of memory as well as a 6GB micro SD card. ?My memory settings are:
- SD Card: total space - 5.43GB; Available space - 5.43GB
- Device media storage: Total space - 2.48GB; Available Space - 2.3 GB
- System storage: Total Space - .97 GB; Available space - .59GB
In Settings>Applications>Manage Applications, the "On SD Card" tab lists several programs lists several apps but none of them are actually on the external SD card.

E520 - HDMI Output not working on Samsung TV - although works on other devices

Laptop does not recognise TV
I know there are a number of threads with similar questions, I have been through a number of them, however have not come across a solution that works.
I have a ThinkPad E520 running Windows 8.1 Enterprise Edition x64
The Laptop has two Graphics adapters
Intel HD Graphics 3000 (Drive - 9.17.10.2867) - I have recently reverted back from the latest Intel driver to the latest Lenovo
AMD Radeon 6600M and 6700M Series (Driver - 13.251.9001.1001) - latest on AMD website
The TV is a Samsung 5 Series 5200 58 inch
We use the TV at work for presentations and demo etc
At my desk extend my desktop to a Philips monitor via HDMI and have no problems at all, I also using with HD TV at home, so HDMI port is ok. Other laptops us the TV fine, so nothing wrong there either.
Things I have tried
The obvious 'Windows key + P' extended, duplicated, restarted and tried again
Did the same as above using screen resolution page - TV is not detected, tried hitting detect - nothing
Disabling AMD adapter
Uninstalling Intel HD and reinstalling latest INTEL drivers with HDMI output plugged in
Uninstalling Intel HD and reinstalling latest LENOVO drivers with HDMI output plugged in (as suggested in other posts)
Tried different HDMI cables, using HDMI input 1 and 2 in the TV
Initially you may think its the TV, however we have a number of Lenovo E530's they all work, the problem only exists with the E520's with the switchable graphics.
Any help would be greatly appreciated.

Hi- its working now. The problem is that all your contacts needs to update Skype and have the latest version and then bingo - it works. Its fab now.
Problem solved and set for Christmas call around.
Merry Christmas everyone

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.

HDMI Output Failure on 2-Mini's After 10.9.3 Update

I have two separate (Late 2012, OS X 10.8) Mini's that are both (2.6 GHz Intel Core i7, 16 GB 1600 MHz DDR3) that have been hooked-up to identical Flanders Scientific professional HD monitors via HDMI cables from the computer output to HDMI / DVI adapters into the monitor input and they have worked flawlessly in that configuration since purchase in July of last year. THAT IS UNTIL, I made the stupid mistake of installing OS X 10.9.3 ---
I updated both Mini-A and Mini-B within a few minutes of eachother while they remained online and wired to the monitors in that identical configuration. Mini-A was the first to complete the download and install of 10.9.3 and when it rebooted, the display image did not return. Subsequently, a few minutes later, Mini-B completed the download, install and reboot with the identical result of missing display image.
Monitor info:
2 x Flanders Scientific LM-2140W, 1920x1080, 10 bit, switchable multi-input (2 x HD/SDI, YPbPr & RGB Component, 1 x SD/SDI, DVI-I / DVI-A / DVI-D switchable YPbPr / Limited RGB / Full RGB)
Needless to say, I have been fiddle-f***ing around trying to resolve the issue for more than a week to no avail. The HDMI output signal is no longer present on both computers and the only way to feed a signal to a monitor is now via the thunderbolt / mini-display port output using a Mini-Display Portt to DVI-I or DVI-D adapter at the computer to DVI cable into the monitor.
Troubleshooting Procedure included.
PRAM / NVRAM / SMC Reset (no change)
Alternate Cables (no change)
Alternate Monitors (no change)
Alternate Computers running OS X 10.8.5 via HDMI wiring schema as before (image on both monitors)
I'm no GENIUS, but I do have a modecum of experience with troubleshooting this kind of stuff and I am 100% confident that OS X 10.9.3 has caused this problem. Now, who wants to tell me how to fix it before my warranty runs out in 45 days.

So to be clear, this issue occurs on any input with the Denon Receiver. Occurs from both HDMI out and MiniDisplay Port out. Goes away when we reinstall the OS and update it to 10.9.2. Comes back as soon as we update to 10.9.3.

Have you been able to use the Mac Mini directly attached to the plasma/LCD/projector with out going through the Denon AVR? Even with 10.9.3 installed?
I have a Pioneer AVR and I have the Mac attached via a HDMI to HDMI and all is working for me. Can your Denon do some upscaling? Some AVR, like my VSX-53 can change the scaling of the input video. Meaning if I still had my Apple TV 2 which outputs 720P only, can be upscaled in my AVR to 1080i or 1080P or even 24fps. Heck, I could even plug in an old style Red, White, Yellow cable and upscale it to 1080P and output it HDMI.
I am wondering if your Denon is able to do that and it might be set wrong. Check the owners manual for such settings. Even the plasma/LCD/project could be doing the upscaling too. So check that too.

HDMI output to TV is no longer working

I've seen similar problems posted here and have tried most of the "solutions" but nothing has worked....
A few months ago, the HDMI output worked fine; I plugged the HDMI cable into my laptop and didn't have to change a thing (no resolution tampering, no audio trouble, no projector selection). Some time last month, I started getting the "signal not supported" message on my TV (Sony Bravia LCD), so I went and tinkered with the resolution settings and eventually got it working again. The other night, I started having audio problems. I could hear a slight hiss or buzzing, but that's it. Before I could attempt to solve that problem, the TV stopped detecting my laptop altogether. Now, I plug in the HDMI cable and nothing happens. I just get the "No signal" message from my TV as if nothing is connected at all. Sometimes, the laptop makes the "connecting new device" sound and the screen goes black as if it's connecting to the TV, but then nothing happens; the screen comes back on and never connects.
As far as I can tell, all my drivers are up to date. I just did a BIOS update yesterday to see if it would change anything, but it did nothing. Any suggestions?

it was working when I first had the computer but cannot get it working for love or money...Running windows 8 64 bit Please please help

hi no-need,
Can you try to:
1. Update the chipset by running the Intel Chipset Update Utility. After the update, open Device Manager > System Devices > right click & choose properties on the Intel H61 Chipset and ensure that the driver is updated (v9.4.0.1022). if you get an older driver, try to update the driver manually by clicking on Update Driver and point it to the new Intel Chipset Driver folder.
2. According to this pdf dataheet, you have the Nvidia GF 615M. Try to check if you have this driver version and update it if necessary
Nvidia VGA Driver
v9.18.13.593 / Win8 64bit

[SOLVED] How to use the HDMI output of my laptop (Openbox)

Hi everyone
I use ArchLinux along with Openbox, PcManFM, LXterminal (no desktop environment) on my Asus X52F (CPU/GPU = Intel core i3-350M).
I'd like to be able to use my HDMI output to watch movies on my TV.
When I used it with Ubuntu/Linux Mint, the HDMI output worked out of the box when I pressed Fn+F8 on my keyboard, but now it doesn't anymore.
I guess some packages or configuration are missing, because my others multimedia keys (Fn+Fx) to control the brightness of the screen, sound volume... are working, but since I didn't find anything on the wiki, I'm asking you.
Thank you ;]
EDIT: Arg, wrong section, sorry
Last edited by Lowra (2012-02-13 22:26:28)

What I did to solve it:
- Installed "lxrandr" from the official repo
- Configured Openbox to launch lxrandr when I pushed Fn+F8.
Now, If I want to watch something on my TV through HDMI:
1) Push Fn+F8
2) Tick the HDMI button under lxrandr, and click Apply
3] Enjoy :]

Split HDMI Output to 2 HD TVs

I am trying to split the HDMI output from my Motorola 6416 HD DVR to 2 HDTVs using RocketFish Two-Way HDMI spillter. The splitter is HDCP compliant. However, when attempting send the signal to both TVs the apparently the handshake gets messed up resulting in DU1 error on the box. After resetting the box I can watch one TV at a time.
Has anyone had success splitting HDMI to 2 TVs? If so, what splitter did you use?
Thanks,
Matt

Is that splitter powered by any chance? Becuase I use this from Monoprice with the same setup and it work perfectly. There are a few others in the same cat. and they all work well.

Lenovo V560-43422GU laptop - which wireless card and is there HDMI output

Regarding Lenovo V560-43422GU laptop:
(1) Is there an HDMI output? Lenovo sales rep says YES, but Bestbuy.com specs say NO.
(2) Which wireless card is included? Lenovo gave me a list of possibilities, but said the card is actually specific to each dealer/store. Please tell me which one of the following cards will be in the laptop if I buy it from Bestbuy.com.
Intel 6250
Intel 5150
Intel 6200
Intel 1000
Broadcom 4313
AR 9285

Very good questions with no precise answers online.
I see you already posted on the Lenovo forums and they do not have an answer for you right away I love how the tech says he will contact you in a FEW days... and it is their product. I had a smiliar situation with them and it took 3 days lol.
Again, I see you did your searching well... not a lot of information seems available.I guess physically seeing the computer can verifiy this.
Looking at image #4 on the Best Buy site shows there is an HDMI port, but it is covered.... and that concerns me especially when the SPECS say it does not have an HDMI port. I really do not see why it would not have an HDMI port available, even the lower lines of Lenovo z565 and b560 have them available.... it is almost becoming a standard now days for HDMI.

I will be at a Best Buy on Thursday.
If you do not get a reply back by then I will be there and physically check the machine for the HDMI and interally for the Wi-Fi card that is in there...
But hopefully you get a more informational reply before then =)
I will check back in on Thursday.
Let me know if you have any questions before then.
Good Luck to you.

Portege M800-105 - HDMI output driver for XP?

Hi,
I've got a question wich belongs to the HDMI output.
I have put Windows XP Home on my Portege with all driver from the Toshiba support page but my HDMI out does not works.
Now I've seen that there is a driver for Windows Vista called Toshiba HDMI Output.
Does anybody knows a driver called like this for Windows XP?
Or has anyone the same problem working with XP but the HDMI output does not works?
I hope someone can help me with this problem.
thx

Hi
As far as I know this is a Intel High Definition Audio HDMI driver.
Im not a M800 owner but Ive got a U400 Satellite with HDMI output and installed XP.
To be honest I didnt notice any yellow exclamation marks in my device manager but I installed the Intel High Definition Audio HDMI driver from the Intel page

Maybe this site will help you
But note; some notebook features are not available in Win XP but only running Vista!

HDMI output doenst work

Hi,
I have a z930 ultrabook and im dying to get the hdmi output work.
It works fine when i connect to a TV.
However, doesnt work at all when i connect it to a VGA screen and use the VGA to HDMI converter.
I tried to use it on a normal laptop, works fine.
Is it because my laptop wont take any converter or what?
P/s: I need to use 3 screens at work so that's why i need to use the hdmi socket. The other VGA socket works just fine
If anyone could help, I would really appreciate it

This HDMI connection still does not work. It only shows on the TV not on both. I have spoken to Toshiba Software and they have a fix which are some special tools at a one off charge of £84. They say the problem is to do with the HDMI only sending at 30 Hz and the TV being at 60Hz. They also say the fix will provide mirroring as the resolution of the TV and Encore are not compatible. As I only paid £177 for Encore I am reluctant to pay such a high amount. They also advised that you must be connected with the mains adaptor because the battery is not powerful enough to sustain the signal. My laptop works fine and I have a new HDMI cable for Encore.
Any further thoughts?
