Lion update to 2010 hdmi Mac mini and Samsung TV via Pioneer receiver

Hi, having updated to lion a message appears on the screen of the TV that this resolution is not supported, but I have no screen to change. Ideas and solutions gratefully received before I return to snow leopard. Paul

Hello!
I have the exact same issue. Also with a Marantz (SR 6009). Can you tell me what settings you did change?
Thanks,
JC

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.

New Mac mini and Samsung Tv

Dear all,
A little help please. I have just purchased a mac and mac mini. I would like the I Mac to run as the master and the mac mini to work on the tv downstairs.
The mac mini works when connected to a monitor however when I try to connect it to my tv my screen is black.
I am currenlty trying to connect via pc connector lead as there was nothing else in the store so I am connecting via mini dvi adapter to DVI cable to female connector to pc slot in the back of the tv!
And its not working.
I have downloaded chicken of the VNC onto the I Mac and have installed some program called Display config X. however whenever I plug it in it doesnt seem to want to play.
Any thoughts or should I abandon the pc connection on the tv!

I have a mini connected to my Samsung.
I have a miniDVI to DVI adapter that came with the computer linked to a DVI to HDMI cable.
I've since learned you can buy a miniDVI to HDMI cable, thus eliminating the need to the connection, which is probably a good thing.
In any case, if you can go into the HDMI slot instead of the PC slot, you will likely have better results.
This is my second Samsung TV. The first one actually had a DVI in to begin with. But it was smaller than my iMac screen, and I needed binoculars to read it from across the room.
I also had to do an adjustment to get the menu bar to display properly. It was a rescan or something. Search the forums for my name and Samsung and you will find it.

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.

Mac Mini and Samsung 42" Plasmas

I'll be purchasing a Samsung HP-T4234 plasma soon and have noticed it will handle a PC signal of 1024x768. I realize it's not a very sharp resolution, but will it fill the entire widescreen? IT won't need to be stretched, will it? I'm not too sure of these types of things, so any help would be greatly appreciated. Thanks.

I am using the Samsung 204B, not sure if this is similar. I have an XP Pro machine (older) and my Mac Mini (current version) on a DVI KVM switch. I noticed if you loose the connection to the Windows PC I have to restart the computer to get the display back.
My video for the Mini would drop out every so often. I had to download SwitchResX and set up a custom setting of 1600x1200 with a 135MHz pixel clock for the monitor to work well with the Mini.

Trouble with Mac mini and samsung 5 series tv

Hi there, have just bought a second hand mini and trying to hook it up to my samsung 5 serties tv!!! easy or so i thought!! iget the apple loading screen (grey one!) and then it goes blank and nothing else happens! has anyone got any suggestions? thanks in advance!

If you look through the threads here you'll find that this sort of issue has come up quite often, both with TVs and even with some monitors. Typically the problem is that once the system has booted to the point that the screen changed from the grey one with Apple logo, it's loading the preferences previously set in MacOS. When that happens, if the system has display preferences set that the display itself can't work with, the screen will generally go blank, or show a very distorted or rolling image. If your mini had previously been used with a relatively high resolution or refresh rate setting which your TV can't cope with, it means you need to reset the mini's preferences to something more basic, at least to get you going.
You can do this in a number of ways, but the easiest is probably to go ahead and connect the system to a computer monitor and boot it up, then set the display preferences to something very basic such as 800x600. If you don't have a computer monitor to connect to, then instead, boot the system into safe mode by holding the shift key down as the system boots. This should set it to a basic resolution the TV can manage. Open the display preference pane and set a 800x600 resolution.
If that still doesn't help, boot again (to computer monitor or into safe mode) and in the Finder's Edit menu, use the Find command to search for all instances of 'windowserver' (no quotes) and drag all instances found (there should be 3 or 4) to the trash. These are the files that tell MacOS what settings to use for the display, so trashing them will prevent the system using previously settings. After that, reboot normally. With those files missing, the Mac will create new ones when it boots and loads MacOS, giving you a usable display at low resolution. You should be able to work from there to get the correct resolution set for your TV.

2010 Mac Mini and HDMI question

Just bought a new Mac mini and have it hooked up to a Samsung px2370 HDMI to HDMI and as good as the picture looks I'm thinking it could look better ... And I've heard that generally a computer shouldn't be hooked up that way... The Mac mini has another mdp and the Samsung has dvi also, what are my options? All these adaptive have me stumped... Plus like I've heard On another thread the mini is thinking I have a television hooked up... Plus when the monitor was on 16/9 the menu bar was not visible and I changed it to screenfit on the monitor which worked but should I of kept it on 16/9 and adjusted it with underscan? Plz help

It works ok for me, I've got a 2010 mini (base model) and am using it as a server for web, iTunes and VPN. It handles lion fine, the only quibble is that being always on it heats up during the day a lot, more so than when I had Snow leopard installed. It's not to unacceptable levels though. But as dingy and beezelbubba say, Ram is cheap nowadays and if you've got the spare cash it's always worth it.

I have a 2010 Mac Mini and am thinking about upgrading to OSX Lion.
Although I know my Mac meets the system requirments (Intel Core 2 Duo, 2Gb RAM), I was wondering what the performace is like on with these specs.
I mainly use my Mac for iTunes, Safari, Twitter and iPhoto if that makes any difference.
Thanks!

I have a new MAC MINI and I want to install a second monitor. I have one connected to the HDMI and it works. I can't get a signal to the other one. It is connected from the thunderbolt to its HDMI port. How can I make it work?

Could be a bad cable or bad Thunderbolt port.
You have 90 days of free telephone support on a new device. You can call them at 1-800-MY-APPLE. Have your Mini's serial number handy
You can also make an appointment at the Genius Bar of an Apple store.

Mid-2007 Mac mini and HDMI issues

I have a Mid-2007 Mac Mini with OS X 10.7.3, that, most of the time, will work fine with a DVI->HDMI cable and either of 2 HDMI ports on the TV. The Mini recognizes the display correctly (a Vizio E371VL). The display's native res. is 1080p at 60hz, and the Mini is set to that and looks great. I can switch to lower resolutions and even restart the mini and have the Vizio look and behave correctly.
However, I have an Apple TV (current generation - black brick) hooked up to the other HDMI port on the Vizio. It also looks and acts great.
The problem is when I switch between the inputs on the TV. If I go to the Apple TV (which will be working fine) and then back to the other HDMI input, the Mac mini shows black. The TV does not say "no signal" or indicate any problem. No amount of zapping PRAM, ressetting the SMC or basic restarting helps. In fact, the TV still registers a signal at 1080p. Using Apple Remote Desktop from another Mac (a 2006 Macbook Pro with DVI) shows the Mini is still functioning and still correctly displays the Vizio model and 1080p @ 60hz resolution.
The kicker here is that I can physically disconnect the DVI/HDMI cable from the Mac mini and connect it to the Macbook Pro. The video from the Macbook will pop up immediately. I can switch between the Macbook and Apple TV all day long, switch resolutions, etc. No problem.
Even more bizarre is that this has the effect of "resetting" the Mac mini. If I plug the DVI connector back into the Mini, its video will pop back up. It will work fine as above until the HDMI input is changed again.
Vizio tech support acted as if they'd never heard of Apple, Inc. Useless.
Super frustrating problem.

Opperman,
I went with my gut and got an LG 47LM4600 TV with VGA input in addition to HDMI (seems there are not many--if any--TVs sold with DVI inputs anymore). The 2007 Mac mini is plugged in using my old DVI cable with VGA adaptor. I tested it using the DVI cable with HDMI adaptor, and there was no sound.
I can confirm the same condition that you originally described when I try to switch to the Mac mini on the PC input. The screen is black except for a color bar that flashes on briefly every 2-3 seconds at the bottom of the screen. No amount of switching from one input to the other will make the display come back. The only way I've found to fix it is to unplug the cable from either the TV or the computer and plug it back in.
The annoyance with this is ameliorated by the fact that we'll be using a new Apple TV to watch Netflix from now on, instead of using a Web browser on the mini. Will only have to worry about it when watching DVDs.
Cheers.

My airport time capsule will no longer allow our iPhones or vizio smart tvs to connect to it, though my iPad air mac mini and mac air connect fine. Why is this? does a recent software update have anything to do with it?

What model is your TC? What is the firmware?
I recommend you do a factory reset and use short names.. not apple recommended names.
Short.. 2-20 characters .. less than 10 even better.
No spaces.
Pure alphanumeric.
Set fixed channels for 2.4ghz wireless.. test with 11, 6, 1 at least.
That often helps.. if not and is old, ie Gen1-4 go back to 7.6.1 firmware which is far more solid.

I upgraded to Lion on my Mac Mini and I'm wondering if I have to pay 29.99 again to upgrade to Lion on my Mac book pro?

I upgraded to Lion on my Mac mini and I'm wondering if I have to pay 29.99 to upgrade it on my Macbook pro also. Or since both computers are registered under the same account, is there a way to share the program?

You can download it from the mac app store again on the other computer free of charge. Just go to purchases in the mac app store on the other computer and log in with the same account you used to purchase lion. Then you should see lion listed as a purchase along with a gray box that says INSTALL.

I have a mac mini and just purchased a moshi hdmi connector for my LED TV. The problem is, I wanted to be able to take my mouse from one screen to another, not just as a mirror image! Is it possible to do this some how?

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
If you have two displays attached, then the function to change from mirrored to extended Desktop will appear in System Prefs/Displays.

Updated iMovie on my brand new mac mini and lost "SPEED" function.

Hello bbryson68, I'm sure you've just over-looked it.
The answer is to click on Adjust above the Clip in Viewer, this will bring into view a adjustments bar also above the Clip.
Now you just have to select the speed via the Turtle icon. Once the clip has been speed-up or down, you'll get a Slider
over the clip in question & a Rabbit icon indicating the clip has been speed-up.
If you want to keep audio undistorted check the Preserve Pitch checkbox above the viewer.
The Clip Slider & icon of Rabbit appear in the Clip-Trimer window below the main Clip, also check your Pref's to see if you have
Apply Slow Motion checked? This will slow or speed up all other clips to the first clip.
