HT3180 Apple TV no display settings on Plasma Television?

I have a Pioneer Plasma TV with HDMI input
Connected HDMI cable to Pioneer TV and other end of HDMI cable to Apple TV.
Connected power cable to Apple TV and light shows power on.
Turned on Pioneer TV and selected HDMI input but only see ablck screen
Any suggestions as to what may be the problem and how to correct?

Are you sure you selected the HDMI input that the ATV is connected to? Are you sure ATV is not actually connected to an output?

Yeah, I'm having the same exact problem - It seems that the thunderbolt minidisplay port is only able to output the analog VGA signal, not the digital signal to support DVI and HDMI. This is a bug that came up after installing 10.7.1. I bought my macbook air with 10.7 on it, upgraded it to 10.7.1 as soon as I got it, so I have never been able to use hdmi or dvi with my macbook air. This is an extremely frustrating problem for me, I used HDMI on a daily basis with my PC. I have spent many hours at the genius bar running diagnostic tests so Apple can get as much information as possible to create a fix for this problem. I have been emailing tech support for 3 or so weeks now, they keep saying that they are working on a fix and it should be out soon, but 10.7.2 has come and gone and I still have no HDMI functionality with my MacBook Air!

Display settings in System Preferences acting up

I'm having trouble with my Display settings under System Preferences. I am not using an external monitor. My display seems to be working fine, but when I open Display settings to change resolution and colour, weird stuff happens. Basically, I cannot use this preference pane at all.
My display is 1920x1200, but when I open the Display settings, I get two windows, one telling me that "I am about to change [something something], some applications cannot display information correctly if the screen has less than 800x600 pixels", and the other one, the usual main window, telling me that my resolution is now 640x480 (it isn't).
If I hit OK in the extra window that pops up, my resolution changes to 640x480 or something similar, and I am unable to change back unless I reboot. Also, in the main Display settings window, it says <<< DO NOT LOCALIZE >>> under the list of available resolutions, as well as << do not localize >> in the box where I can change refresh rate. None of the buttons seem to be working.
Does anyone have any idea what is going on here? This was working just fine when I received my new MacBook Pro a few days ago, but now it's not. I've been repairing disk permissions and rebooting, etc.
I have been installing the trial version of Adobe CS5, but had massive problems with this installation (as a lot of people are reporting with CS5 and Snow Leopard...) and uninstalled them again, cleaning out Adobe preference files. Could I have deleted some other important files by accident in this process?

Quit System Preferences, then delete these files or folders.
Users/yourname/Library/Preferences /com.apple.systempreferences.plist
Users/yourname/Library/Preferences/By Host/com.apple.systempreferences.xxxxx.plist and com.apple.PrefPane.Network.xxxxx.plist (the X's will be numbers)
Also, Users/Home/Library/Caches
Now relaunch System Preferences. Let us know.

Monitor says VIDEO MODE NOT SUPPORTED after changing display settings

HELP! I am about to have a nervous breakdown with my mac mini! I hooked up the mac to my Philips LCD via DVI. No problem at all. But because the screen is only 15" I wanted to play around with the display settings a bit. So I changed the resolution from it's original 1204x768 to the one higher (not sure of numbers) and to my HORROR, I now can't get any picture at all - it says "VIDEO MODE NOT SUPPORTED". I have tried everything I can think of. I have rest the P-RAM, I have unplugged all cables, plugged the back in again, I bought the mac into work and hooked it up to my monitor and changed the resolution back to 1024x768 which is what it was on originally and that STILL didn't work. I can see the Apple logo and then it goes black and comes up with the error message. HELP! What am I doing wrong - I can't believe one click of a mouse button has rendered my display useless!!!

Welcome to Apple Discussions!
Try booting the mini without the display connected, and then, once the system is running, connect the display. This will often force the system to default to a low resolution, and then correctly detect the display when it is connected.
If that doesn't help, with the display connected, boot into safe mode (hold the shift key down when starting up) and once the system is running, change the resolution to 1024x768, and ensure the correct refresh rate is selected. Rebooting normally ought then to give you a good display.
If all else fails, boot into safe mode with the display connected, and then in the Finder's file menu, use the 'find' option to search for 'windowserver' (no quotes). You should get 2 or 3 results, including one with a string of alphanumeric characters. Move all of them to the trash and restart normally.

VMware Fusion and Apple LED Cinema Display

I have a 2008 MBP and a 27" Apple LED Cinema Display. My OS is 10.7.2.
I am running Windows 7 with the latest updates in VMWare Fusion 4.1.1. I have several issues.
1) When I go to chose my monitor it say Apple LED Cinema Display but "Generic Non-PnP Monitor." I downloaded and installed the boot camp drivers as I understood those contained the drivers for the monitor, but that didn't seem to help. Do I need to have the Boot Camp drivers?
2) When I try to access the Boot Camp Control panel in Windows 7 in Fusion I get "An error occured while tyring to access the startup disk settings. You may not have privileges to change the startup disk." My guess is this is because the Boot Camp drivers are only needed if you actualy run Boot Camp.
3) In Windows I cannot choose the native resolution of the Apple display (2560 x 1440).
4) The resolution ia 1277 x 1234. That is weird.
5) If I minimze the Fusion window and then immediately open it, it looks fine. But if I wait for awhile and open it, the window will be black until I click inside of it.
Something is wrong, Any help in fixing this would be greatly appreciated.
Bryan

you have to separate out what is Fusion and what is Windows native.
Even doing updates to Windows sometimes should not or cannot be done properly in VM.
And there is no way to change the default boot drive - a VM doesn't have access and that is the host OS's job, not the guest's.
Install the latest AMD driver for mobility - and dont' use the "auto detect" - that is not going to work on Apple hardware.
You dont' run Boot Camp. But the Apple drivers and serives needed for hardware support, yes, they aren't running or loaded.

2560 x 1600 is gone from my display settings (2nd monitor)

I've been running my 15" retina macbook pro for more than a year now with 27" DELL monitor and it has alway been using 2560x1600 resolution display.
In the past year i've had no issues with mirroring my screen to big screen TV using Apple TV, however today something weird happened.
As usual i mirrored my screen using Apple TV to watch some videos and i had to change some of the display settings to get the best view on my TV.
Afterwards i switched off the mirroring feature and now my 2nd monitor (DELL 27") is displaying 1920x1080 only. I looked at all my options on my display settings (using ATL+click ) and 2560x1600 is gone missing from the list. Im frustrated and couldn't find an answer to this problem, please advice.
Couple things i tried;
- restart & shutdown
- reset NVRAM & PRAM settings
- changed mini display cable with another
- reset monitor settings
Weird find:
I tried to mirrored my macbook pro to apple TV again to see the display settings. Guess what, the option for 2560x1600 is now back on the list and working (visually) just fine. as soon as i turned off the airplay display my 2nd monitor turns back to 1920x1080.
Note: the display on my retina macbook pro is working just fine, no problem at all. this is only showing on my 27" DELL U2713HM.

Hello! Just want to ask about mirroring: when you MIRROR the Retina MBP 15" to your Dell Monitor (2560x1600) : do both the MBP and Dell Monitor look sharp and crisp?
I'm asking because I'm also considering a monitor that's at 2560x1600.
Thanks so much!

How to reset display settings?

My Sharp TV only support 1080i, so I use a DVI-DVI cable to connect a monitor, then use Mini DisplayPort to HDMI adapter connect Sharp TV.
Then boot Mac mini, I got Open Screen on Monitor, and I set HDMI adapter to 1080i, then I power off and unplug DVI cable and boot again.
Well, I got what I want on Sharp TV, it is 1080i, but I found a 720p, I selected it, now the TV becomes to black screen with "Invalid video signal"!
I reconnect monitor, so Sharp TV is ok, but if I unconnect monitor, the sharp TV will be black screen.
I thought it might be some display settings are saved, because it was good when I first use TV after set to 1080i, but I selected 720p that is PAL TV, not for mine NTSC TV, after that selected, THe sharp TV can't be used alone, how can I reset display settings? what can I do for this case?
Please help me, GOD!

In the folder of your main user account, which is generally a folder with your name on it, find and open the Library folder. Then in the Library folder open the Preferences folder. In the Preferences folder open the folder named ByHost. Inside that folder is a file called com.apple.windowserver.xxxxxxxxxxxx.plist where xxxx is a string of numbers and letters. Drag that file out onto the desktop and restart the mini.
When OS X restarts, if it finds the above mentioned file missing from the expected location, if should build a fresh copy of the file in the original location. The fresh copy will have default values in it so the Mac will forget that bad setting that happened. Hopefully that will cause the display to work again.

Odd desktop/display bug - how to reset user display settings?

Greetings all,
I woke up yesterday morning to a puzzling problem with my G5. I logged in and started working - and I needed to use the windows remote desktop client to shell into a machine at work. I noticed that the fonts looked sort of funny (randomly quished) so I logged out and then back in. Then I noticed that the problem was not in the RDC display, but in the display of my mac.
This is sort of hard to describe w/out actually seeing it, but here goes...
When I move my mouse across the desktop (or what ever apps I have open) and the mouse pointer moves across and invisible (yet perceptible) line on my screen real estate, my background, icons, parts of displayed apps and fonts "shift". This causes fonts in the affected are to get messed up and causes general display irritation. That's the best way I can describe it, it's sort of a "you have to see it" problem. I will also note that this problem did not arise after an update or a software install or weird crash. Just another day.
So first I tried messing with my display settings (change resolution, color profiles, setting the background to a solid color, turning off screen saver). Rebooting. Nothing. Still there.
So next I log into another account (the root account). Ah ha! No display problems! Tried creating another user-level account. No problems there either. Now we're getting somewhere - it's something that is effecting my main user account and not a problem with my monitor, video card or OS. That's good.
So since then I've tried:
- Grooming the disc that my home directory lives on with DiskWarrior.
- Repaired permissions.
- Deleting the contents of home/Library/Fonts in case it's some funky font rendering issue causing this.
- Deleted the contents of home/Library/Preferences/MicroSoft to get any of its potential badness out of my life.
- Scanning with FontDoctor looking for bad fonts.
- Deleted my desktop and finder plist files.
- General maintenance and cache cleaning (including the MS font cache) with Onyx.
- Booting to Safe Mode.
Nothing. The display problem persists afflicting that one user account. All other accounts (root, and a second user-level account residing on the same disc) are free of these problems even though they are all using the same display settings (monitor, resolution, color profiles, etc). And as already noted, this problem was not "brought on" by anything like an update, installation, preferences modification or fatal seeming crash of an app.
So, my question to all you good people is: what am I missing, what might be causing this and what else can be scrubbed from that account (cache, plist files, etc etc) that might be harboring and causing this display bug? I would really rather solve this problem than go through the very very arduous task of moving all of my stuff to another account (an option, but a very unattractive one).
I was not a mac user during the OS 9 days, but I remember my co-workers doing the "rebuilding the desktop" dance. I realize that this is no longer an issue, but I guess I'm looking for something like that. I need to remove any and everything from my user account that has anything to do with display and font rendering since it's obviously some setting lurking in that account causing the issue.
I googled and searched the forums for this yesterday but could not come up with anything like it and all of the maintenance tasks I tried have not worked.
Any ideas?
Cheers,
Monte
G5 Mac OS X (10.4.9)

Hi.
What kind of G5 do you have? An iMac or a PowerMac?
A PowerMac.
If you own a PowerMac, you'd better take a look (o
try with another one) at the DVI cable connecting the
display.
I did check my connections, but also, why would a faulty DVI cable only cause problems with a single user account and none of the others?
If you want to reset the display settings, start in
Safe Mode, and trash these files:
/Library/Preferences/com.apple.windowserver.plist
/Users/yourusername/Library/Preferences/ByHost/com.a
pple.windowserver.some_number.plist
If I were at home now, I would try and report back. But I'm not. I'll definitely give it a try as soon as I can. Thanks for the pointer!
Cheers,
M

Reset Display Settings

Hello,
Ive just did the Display Update and it reset the screen resolution to 800/600 when it was booted again. When i changed it to what i thought was the right screen resolution, the display turned to black and the monitor displayed a "Not supported" message. I tried to reboot the mac mini using Safe Mode (holding shift) but it wont reset the display for some weird reason. I also tried resetting the PRAM but that didnt work either..
Is there anything i can do to make it reset back to where it was when i first booted after the update?
It must be done on boot.. is there a command line interface somewhere during boot i can go in and change some settings there?
Thanks for the help.

Hi and welcome to Discussions,
a PRAM reset http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html should reset the display settings.

Change display settings to show mac on tv

I bought the cables in order for me to hook my macbook pro up to my plasma tv through and hdmi cord and converter. The first few times I hooked it up I was able to drag the screen over to the tv and it worked perfect, now it is not working and I'm not sure why. I have tried adjusting the display settings to see if that was the case, but it doesn't make a difference. If anyone has any suggestions it'd be appreciated!

It's not there. In Mountain Lion, the Displays options have changed somewhat:
It only shows the external display option when a display is detected.

Apple 21" studio Display monitor-help

I have a G4 and just got an apple 21" studio display monitor
I work in photoshop CS2 what do I put the resolution at? Color and refresh?
what should the white point and gamman be? what should the profile on themonitor display?
I WENT INTO THE PREFERENCES AND LOOKED AT THE DISPLAY..THANKS..JAN

(for my photos the service I use said to use sRGB the resolution)....
Then open CS2 and under Photoshop scroll down to Color Settings, go to Work Space and set the RGB tab to sRGB. At the top of the menu under Monitor it should be your Apple 21" Display.
If it is not then it will change after you calibrate the monitor. Open System Preferences/Desktop and change your desktop to a medium gray (you can change it back after you make the necessary color corrections). Now choose Display, select your preferred screen resolution, and millions of color. Now choose Color from the upper tab to Calibrate the monitor. If you check the box "Show profile for this display only" the menu will be simplified. Now select Calibrate and use the professional mode. Just follow the on screen instructions and do all of the color setting using the 1.8 gamma and native whiter point.
After the monitor is calibrated you will be asked to save and name the calibration. I would recommend a name similar but different from the default Apple 21" Display setting, you can even include the date if you calibrate often.
Reopen Photoshop and check the Work Space the RGB/Monitor the setting should be your recent selected calibration.
