Mac Mini HDMI Samsung HDTV colors washed out

Hoping someone can point me in the right direction. Just upgraded from a 2009 Mac Mini to a new one. Using HDMI, the colors are washed out and off (greenish purplish) at the default 1360 x 1768. If I pick one of the other (like 720p) the colors are right but resolution is screwy. Any thoughts?
And... Thank You.

If you haven't already, make sure all firmware
is up to date. There has been some recent updates
that may not have made it to your machine.
As for the 720p issue, go to the Samsung setup
screen that deals with screen size and set the mode
to "Fit to Screen". Pretty sure it says that or something
similar.

Mac Mini to Samsung HDTV

My new mini should be here Wed. I was going to connect it to my Samsung HDTV. I just noticed that the mini has a DVI-I connection in back, while my TV has a DVI-D connection in back. Is there a cable for this? I'm not having much luck finding one.

I suggest you read this primer on DVI interfaces, it will answer many of your questions:
http://www.datapro.net/techinfo/dvi_info.html#Page02
Basically, the mac mini having a DVI-I plug is good, meaning it can go either way -- DVI-A (analog) or DVI-D (digital). You will simply want a DVI-D cable to connect to your TV, and you should be good. a DVI-I cable would also probably work.

I have no audio from the mac mini to the hdtv via hdmi cable.

This started immediately after the latest "apple software update" I updated it automatically on 6/24/2011. I have an elgato eye tv connected to the mac mini that provides BOTH audio and video through the HDMI to the HDTV. The elgato eye tv works fine. I get both audio and video.
However, I only get picture and NO sound from the mac mini to the HDTV via the HDMI output. No streaming audio either - only picture. Ive tried pandora, netflix, hulu, etc. I even put in a DVD into the mac mini and again I receive a picture through THE HDMI but no audio.
I've shutdown and rebooted. I've disconnected power and reconnected power. I've gone into the system preferences, audo, and highlight the SONY HDTV as the output. But still nothing. I do notice when I toggle between the "internal speakers' and the HDMI option, the audio arrow on the lower right is bright blue during the internal speakers option but is grey when the HDMI option is connected.
I called apple care. Since I'm 98 days past my 90 days of coverage there is no help via human being. They offered me to set an appointment at the local apple store but they suggested I bring down my 60 inch HDTV with me to the store to be sure it is not a "Sony" issue. I hope someone can help me resolve this without having to put this mac mini on craigslist and taking a $ hit.
This was not an issue yesterday. It became an issue after the latest and greatest "update" to prepare our machines for the lovely lion.
Thanks.

I have the same issue. I also have the 2010 mac mine and use hdmi for audio to my receiver. I get audio from eye tv with no problems, but it seems to lock the path so that only it can use that path for audio. If I restart the computer and do not start eye tv everything else works with hdmi audio. I have tried using the system settings and changing the source there but it doesnt seem to matter.

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.

You can in fact buy what you want, no need to go with Apple TV
To connect (wirelessly) your Mac to the HDMI on the TV:
They range from $100 on up.

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!

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.

No sound on mac mini with samsung monitor using hdmi

I have a new mac mini which is hooked up through an HDMI cable to a Samsung L2350 monitor. How can I get sound out of the monitor? Right now, nothing is coming out. I've made sure my setting are correct but still no luck.
Please help!

Which Samsung Monitor....?
A Google Search > Samsung L2350 - Google Search does not turn up any Samsung monitors.
Check your Sound Preferences.
If you don't see the HDMI option in the Sound Preference, try going to the Audio MIDI Setup in Applications Utilities.
If the Sound Preference and Audio MIDI Setups are set correctly, then perhaps you need to either explore the Samsung Manual or try a different HDMI cable.

Mac Mini and Samsung 43" DLP HDTV gets Black Screen Only

Just bought a new Mac Mini with great anticipation for some large screen viewing.
After numerous attempts the Mini has yet to produce anything but a black image with the occasional red or white horizontal line on my 43" Samsung DLP TV. Not even a brief grey start up screen. Just permanently black.
Here's the kicker: I do get a great computer screen image on this 43" DLP TV in Mac OS 8.6 off my ten year old Macintosh PowerPC. (The trouble is it's a noisy older computer and has no bluetooth for wireless mouse & keyboard: and no Front Row with remote control)
I have the VGA cable connected to the "computer in" port on the back of the Samsung DLP TV .
This is with the exact same cable and connection that refuses to work with the Mini.
Earlier attempts at using the DVI port were unsuccessful so for now I am staying with what works on the older Mac.
Some other things I've tried:
-with my Mini hooked up to a 17" CRT Samsung monitor I have tried all available resolution settings at 60 Hz, reconnecting to my large screen Samsung each time, producing nothing but the black screen.
I've tried turning the TV on before the Mini and vice versa
I always check to make sure the PC connection is selected on the TV
As well, I have re-installed the OS onto the Mini to eliminate any possibility of a sofware conflict from data transferred from my Emac
After consulting an Apple technical page (article 303406) regarding Black Screen issues and Mac Mini on large screen HDTVs, I went into single user mode and changed some text as specified. That did't help either
So far I have never seen a grey startup screen at all, only a totally black screen.
Someone in a recent post here or on MacMini.com touched on impedence issues with signals into VGA or DVI ports. The Mac Mini operates on low voltage. Could there be some connection to how strong a signal it produces compared to my old PowerPC with its ATI graphics card?? And just why would that make a difference
I haven't seem my particular issue addressed in this forum or on MacMini.com
Thanks for any help
Mac Mini 1.83 Intel Core Duo 512 Mb Ram Mac OS X (10.4.7) Emac; 604e PPC with G3 Upgrade & ATI Video Card

Just finished testing the Mini remotely with the use of the Redstone software recommended by BSteely in a previous post. Fun Stuff.
I saw the Mini "desktop" on my Emac screen and could control it remotely, even though the mini was connected to the large screen Samsung.
But the "fix" did not progress from there. When I called Apple for further help they were not able to help me tweak my Mini. Apparently there was nothing to tweak.
A second level Apple technician finally told me (after a few calls to both Apple support and Samsung) that this Mac Mini is likely not capable of producing a screen image on my large screen Samsung.
He said the Mini supports "Coherent Displays up to 154 Megahertz and Non Coherent displays up to 135 Megahertz". On his recommendation I checked with Samsung (second tier) and they are not sure exactly what that means. Same here.
Samsung did reply that the "pixel clock (of this HDTV) is 74.2 Megahertz". Again, too technical for me.
The latest second tier Apple guy just told me said that my Samsung 43" DLP is probably not compatible with the output capability of my Mac Mini.
Bottom line
It's all about the output capabilities of the Mini's "Intel Extreme Graphics GMA
The Mini's video output is not upgradeable like the other mac which works with this HDTV.

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

Mac Mini Purchase Question HDTV

Hello,
I want to buy a mac mini for an entertainment computer. I think the hdmi out will be great.
All I want to do is watch movies through my samsung 55" HDTV.
I am wondering if the basic model will be enough or should I get a suped up model.
If I need a suped up model, what do I need. More RAM, Processor Power, or what? I use a shared network drive at home so storage is not an issue.
Thanks,
James

"Watch movies" could mean a lot of things. If you are talking about purchased iTMS content then a minimum configuration will be fine. If you are talking about movies from other sources, then it becomes harder to answer the question without knowing more about the sources.
Certain very high bit rate content, like 1080p at high frame rates and encoded in such a way that hardware decoding can't be used...movies like that could give trouble without some thought and care put into the configuration. But most likely, you will be fine with a minimum configuration.

Mac Mini HDMI output gives bad resolution on external 1920x1200 external monitor

A brand new Mac Mini gives blurry picture with HDMI HDMI connection to an external 1920x1200 HDMI monitor.
very bad start

Hi tlaci60.
I'm experiencing the very same issue you had with your monitor. Mine is a different brand (Westinghouse24" L2410NM), but the issue is the same. Not surprisingly, the resolution of this monitor is exactly the same as yours:1920x1200. Interesting…
Basically,I connect my brand new Mac Mini to my 24" monitor, and it results in a fuzzy and grainy image, with washed-out colors, and text so blurry it's difficult
to read. I'm sure you are familiar with what I describe.
Anyway: I’m kind of desperate, because nothing seems to work .I have tried your suggestion, but it doesn't work for me. I tried other suggestions from other threads and forums... and nothing works either. I just get the same awful look,even though the Mac recognizes the monitor and applies the correct resolution(1920x1200). Nevertheless, it looks just horrible.
Any suggestions? Any ideas? I'm just losing my mind with this, and I already bought every adapter and cable combination I could think of.
Thank you

How to hook up Mac mini w Samsung Le37R82BX tv?

Hi,
I'm planning to purchase a Mac mini and use it with my Samsung LE-37R82BX LCD TV. Detailed specifications for the TV:
http://www.zigzag.am/product.php?id=0147922
The questions I have before committing to buy:
1) Can I hook up the mini with the TV without distorting the picture? I don't want to have a separate monitor, and my main usage occasion would be viewing photos, videos, therefore no distortion is a must. I'm fine with having black stripes on the side of the picture, just don't want stretched image. The max resolution of the TV is 1366*768.
2) If the hookup is possible, what converter do I need to buy? I already have a HDMI-DVI converter (used it with my previous PC), is it ok to hook it up with the Mac Mini's Mini DV to DVI cable? Or should I buy a mini-DV HDMI adapter?
thanks a lot in advance,
Gergely

I use the included mini-DVI to DVI adapter with a DVI to HDMI cable and my picture is great on my 24" LG LCD HDTV. The mini should be able to provide that resolution without issue as long as it can read the resolution output from the TV accurately. Apple suggests that you connect the cables in what some think of as reverse. Start with the TV and work back to the Mac mini so that the mini gets a good read on the resolution requirements of the TV.

Mac mini and samsung tv

attached mini to my samsung 23" LCD hdtv via DVI cable.
I get a picture but there is a black margin around the display.
On boot up the display is full screen but reduces when OS is loaded.
Display is currently 1280*860 (I think - I'm at work at the moment) at 60h
Tried switchres to change to TV to its native 1360x760 (60h) but the resolution never appears in the active column.
Any ideas?
intel mac mini core duo Mac OS X (10.4.8)

I'm using the same type of TV, and I had the same problems with DVI. VGA is the way to go, particularly now that I'm using HDMI for hi-def TV (so I just press the "input" button to swap between sources).
However, my full screen display started failing 2 weeks ago. That was when I installed the EFI firmware update.
Now my screen has "shifted" up a little. The top of the screen image is chopped off (about a quarter of the menu bar) and a thin strip at the bottom of the screen now has random dots on it. It looks like the wrong part of RAM is being sent to the video output! I'd recommend against this upgrade if you don't already have it.

Original Mac Mini with Samsung P2770h LCD

Yesterday I picked up a Samsung P2770h from CostCo. Swapped out my old Viewsonic 22" LCD and it worked perfectly on my Windows 7 system, but not my Mac.
I've tried booting in Safe Mode, but nothing appears on the display. I've tried DVI-DVI and DVI-HDMI.
I've tried booting with the Viewsonic and then swapping the cable to the Samsung, but apart from an occasional flicker, I have a blank display
I checked the ATI website for new drivers for the Radeon 9200, but it said Apple provides them.
I vaguely remember having to change a setting when I first got the Viewsonic, but I can't seem to find the information.
Any help is much appreciated. The new display is so good on my Windows 7 system, but if I can't get it to work on my Mac it will probably go back !!!
Thanks,
Steve

Ok, after several hours more testing, I am making some progress. By logging in to the Mac remotely using LogMeIn I can see what is going on even if the Samsung monitor goes blank. I can successfuly set the Mac screen resolution to anything, except the native 1920x1080 The next highest is 1600x1200 and it works fine, but is far from ideal. So my conclusion so far is that the graphics card can't support 1920x1080 which is disappointing, but not that surprising given the fact that this Mac Mini is 5 years old !!! But I'm hoping someone more knowledgeable will prove me wrong
Thanks.
