ATV2 won't output HD to my HDTV

I had a first-generation Apple TV that worked fine with my Panasonic 54" HDTV. My wife got me an Apple TV 2 that will only give me 480p resolution using the same setup.
In researching this problem, I believe the issue is this: While my TV supports 1080i (not p), it will upscale a 720p image to 1080i. The new Apple TV 2, not seeing native support for 720p on my TV, will only send a 480p signal. Since resolution is no longer configurable on the ATV2, I cannot tell it to send a 720 signal and let my TV take care of the conversion and I'm stuck with 480p.
Does anyone know of a fix for this (hacks gladly accepted.) It seems silly to me that Apple would take away the ability to set the resolution manually, but if anyone from Apple reads these boards, please consider restoring it.
Thanks,
--Chuck

Thanks for the suggestion; I already submitted to Apple Feedback -- hoping for a larger audience here. It's straight HDMI, using several different cables (just in case.)
Actually, if the ATV2 left the upscaling to the TV, as the original did, I'd be fine -- my TV would upscale the 720p signal to 1080i. Instead, seeing no native support for 720p, the ATV2 will only submit the 480p signal, which is displayed as is.
Thanks for the response.

Mid-2011 Mac Mini won't output 2560 x 1600 to my Dell U3014

Hi,
I recently purchased a Dell U3014 30" monitor. I've been using it with my PC via Dual-Link DVI without a hitch.
I decided to plug my mid-2011 Mac Mini into it using a MiniDisplayPort-to-DisplayPort cable. My mac recognises the monitor, but won't output at 2560 x 1600, the monitor says it isn't receiving a signal.
If I change the display settings to 1080p the monitor comes to life.
Any help would be appreciated.
Thanks.

My macmini won't output to any display since reinstalling and upgrading to maverick

I recently wiped my macmini and when I reinstalled it, it upgraded to maverick.
Now it won't output to any display. When I first installed it, I managed to get it to work once after turning it on and off several times.
I've tried connecting to both a tv and a monitor, using both display port and hdmi connections.
ive done all these:
Reset the computer's parameter RAM.
Reset the computer's PMU.
If you have an Intel-based Mac mini, reset the SMC.
Still nothing...
does anyone have any suggestions?

Does anything show when booting up?
When starting in Safe Mode?

If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

["SOLVED"] PulseAudio - some applications won't output sound sometimes

So, I have KDE 4 and PulseAudio installed, with VLC as Phonon's backend software.
After startup, I often find that Skype won't output sound at all for seemingly random periods of time. This also often happens (sometimes simultaneously, but not necessarily) to Chromium. Pavucontrol and the KDE audio mixer, don't show anything useful at all in terms of the output of Skype and Chromium, and messing with master output in Pavucontrol doesn't affect anything.
After a completely random period of time (usually a very long period of time), these applications start outputting sound again. It's very frustrating, and restarting the applications doesn't help whatsoever. While these two applications are affected, all other applications output sound perfectly.
I don't even know. I've searched, but I haven't found any similar problems documented elsewhere. Any advice?
EDIT: Solved, for now.

I fixed it (for now, at least!)
I ran the below command:
$ cat /proc/asound/cards
0 [U0x46d0x804 ]: USB-Audio - USB Device 0x46d:0x804
USB Device 0x46d:0x804 at usb-0000:00:1a.0-1.2, high speed
1 [MID ]: HDA-Intel - HDA Intel MID
HDA Intel MID at 0xf9ff8000 irq 47
2 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfbd7c000 irq 17
Basically, my USB webcam, which also acts as a microphone, was being treated as my default sound card. I changed this by creating a file in /etc/modprobe.d with the following:
options snd-hda-intel index=0
Which set my real sound card as default:
$ cat /proc/asound/cards
0 [MID ]: HDA-Intel - HDA Intel MID
HDA Intel MID at 0xf9ff8000 irq 47
1 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfbd7c000 irq 17
2 [U0x46d0x804 ]: USB-Audio - USB Device 0x46d:0x804
USB Device 0x46d:0x804 at usb-0000:00:1a.0-1.2, high speed
The problem isn't ENTIRELY fixed. Skype's still being a bit buggy, but at least Chromium is now playing sound, including in Flash media. Strangely enough, after playing a Flash video (e.g. on YouTube), Skype's sound seems to fix itself if it's defunct.

Macintosh IIsi won't output video

I recently got my hands on a Macintosh IIsi that refuses to boot, I get the startup tone, the hard drive spins, and the indecator lights light up but it won't output video. I have tried multiple monitors and different display adapters without success. I want to know what the next step to fixing it

zmclearan,
Are you using a PC monitor and adapters or do you have access to an original Mac monitor? When you say that it refuses to boot, is it just that you can not see the startup screen? How long does the hard drive noise last?
The next step is the process of elimination. Check the PRAM battery first. A dead battery will affect the video circuit in many machines. Look online for batteries with free shipping. If you go to Radio Shack, they will have replacement batteries that cost more than the computer.
A way to avoid buying a battery is to do what is called a "warm boot." You start the computer, listen for the chime, give it ten seconds, then hold down the command key + control key + the soft power key (the key at the top right hand of the keyboard or top center on some smaller keyboards). If you hear the chime again then it restarted. This gives the computer a fresh start with power supplied by the wall power and not the battery power. For newer computers, you turn the computer on at the power button, turn it off and back on immediately. That will wake up the video circuit on a Quadra 605 or a 6100 PPC. I do not remember ever needing to do that on an 030 processor computer so the on-off-on trick may only be for the power supplies in the 605 form factor.
If you can find a PDS to NUBUS adapter you could test to see if the onboard video is bad by using a NUBUS video card. The IIsi uses built in RAM so it will not be a video RAM problem. How much RAM do you have? The chime means that you have some form of RAM. Incommpatible RAM or no RAM will result in a sad musical sound.
Your best alternative for testing older computers is to find a Mac user group in your area. Someone will have spare parts, monitors and other resources. Your video adapter may not be properly configured and the easiest way to test that is on another machine that you know works with your monitor. Unfortunately, buying the battery is just a gamble. It that does not fix it, you have just spent good money on a bad motherboard problem. Post back with the name of a city near you and maybe we can find a user group to help out with parts.

ATV2 won't connect to my wireless network.

My ATV2 won't connect to my wireless network, although the network shows up in the list of networks and I'm using the correct password. A laptop approximately 1 foot away connects wirelessly to the network. ATV has worked in the past - haven't tried it recently. Tried reset - didn't help. Any suggestions?

If your wireless router is setup to use WPA or WPA2 security then you need to make sure you match this within your Apple TV device.
You probably already know to match case sensitivity in your password.

My new Macbook air won't connect to my Vizio HDTV.

My new Macbook Air won't connect to my Vizio VO32LF HDTV. I bought a mini-displayport to HDMI cable to connect the two. When I connect the cable, and switch to the appropriate HDMI input on the TV, my Macbook Air screen will flash blue for a second, and then return to normal. The TV reports it's unable to find a signal. I use the HDTV as my primary monitor, so I'd really appreciate some help on getting the two to place nicely together!

Cp,
Thanks for the reply. However, it appears that the issue is not with the hotspot, but with the network settings in the MacBook Air as every other device I have (including non-Apple devices) will connect to the iPhone hotspot. Another symptom is that my MacBook Air can find my iMac (and other network devices) on my wireless network, but the iMac can't find the MacBook Air.

IBook (FireWire) won't output to TV

Since my previous topic has already been archived and I still haven't solved the problem, I'm going to ask again.
Basically, once I connect the iBook to the TV (a SONY Bravia KDL-32S2400) with the AV cable, nothing happens. The TV doesn't recognize any input at all and stays completely black. I'm wondering if there is something I have to do in Mac OS X before the iBook will output video/audio to my TV.
This is the AV Cable I'm using:

I've tried clicking "Detect Displays" in System Preferences as well, but that doesn't do anything either, and there isn't exactly much else to do there:

Hooking up a 8 year old notebook to a HDTV screen could be difficult.
I'm not sure if your WXGA (1366 x 768)panel is able to display a 800x600 resolution.
It seems that you have the original cable that came with the iBook
http://support.apple.com/kb/TA27234?viewlocale=en_US
In order to connect your iBook look for the - Video in - jacks on the back of your TV.
AUDIO-L (white)
AUDIO-R (red)
VIDEO (yellow)
Do the cables fit in exacty or are they a little bit too small ?
The Sony troubleshooting guide says:
-Check the connection between the optional video equipment and the TV.
- Press TV/VIDEO on the remote control (page 19).
- If you connect video equipment to the S VIDEO input of the TV, set Auto YC to
On in the Setup settings (page 33).
- Press MENU on the remote control. Select your desired input from the External
Inputs list.

If you get a proper connection, your TV will show up in the monitor settings in OS9 or OSX

ATV2 video judder/stutter on new LED HDTV

Equipment:
40" Samsung UN40D6000 LED HDTV 120Hz 1080P - software all uptodate.
AppleTV 2 software all uptodate.
Basic cable (SD) and HD content while watching television is solid, fluid and vibrant.
However when using the AppleTV playback is stutter/jittery every few moments and the content is all standard definition. Both form iTunes rentals, streaming from an iTunes library and netflix. and its not a streaming issue as I have another bottom of the barrel HDTV 1080p set with an ATV2 and it streams the content just fine no issues. (it performs the jitter/stutter/ when plugging it into the Samsung LEDTV)
I disabled Auto Motion Plus feature of the set and did no justification or stopped the jitter during playback. When I put the setting on Game Mode it played back just fine as per usual, however adjusting the color quality, picture qualiy etc is disabled and am not getting the full advantage of the LEDHDTV
Anyone experience this before? I've browsed through some of the posts and seems alot of complications between some ATV2's and Samsung TV's.

I found this on another forum. Set Samsung Auto Motion Plus to "Clear" NOT off. I also set the AppleTV TV resolution to 720p - 60 hz. Tried it last night on a DVD I ripped with Handbrake and streamed it from my iMac. Finally stopped the jitter. I think I saw one or two stray hiccups during the entire movie. But that's WAY better than the glitch every 4 or 5 seconds before.

Bridge CS4 won't output to pdf multiple images with same filename

Hiya...my googling efforts have thus far failed!
I've got CS4, and in Bridge, I created a New Smart Collection to find all filenames in a folder containing "." or ".jpg" - which in turn searched through all the subfolders like what you used to be able to do in Photoshop CS3. Very simple stuff, but all the images are jpg's, but in multiple folders (I don't want to move them out of the folders, as the files came from an external source, and there are heaps of folders, and I don't want to pdf each subfolder seperately as it will take forever).
The problem is that some of the files have the same filenames (again I'd prefer not to rename, as it happens a lot on this project, and they are all over the place). So whilst Bridge will show the thumbnail images correctly in the content tabbed screen in my New Smart Collection, but once I've done the Output to PDF thing, for example, instead of showing both different images it has pdf only the first image but repeated it twice. And this happens multiple times throughout the pdf, the more times the same filename is used, the more times the first image gets repeated.
I know that it is messy to have multiple similar filenames, but why can't bridge just place the image anyway? It allocated a space for it on the pdf and does show it in bridge, it just doesn't seem to survive the transfer to pdf well.
The only other thing that I have done is use the below link (which was posted on another adobe forum thread) to create a custom pdf output template (nothing too fancy, just number of rows / columns, size, font etc). But I've tried using the standard bridge templates and it does the same thing.
http://www.proficiografik.com/2009/08/03/save-custom-pdf-output-template-in-adobe-bridge-c s4.html
Any help would be appreciated...even if to tell me that I am being unreasonable!
UPDATE 16/11/09
Just to let you know that I seem to have resolved the bug inadvertently with one of the Adobe updates. The below is the link for the AdobeOutputModule-2.1-mul-AdobeUpdate.zip which was released on 2/19/2009 - which allows for headers & footers to be placed in the Ouput pdf. I finally installed it today, and everything seems to be working fine now (i.e. I can pdf multiple images with the same filenames and the pdf will actually show each different image rather than repeating only 1 of the images).
Must have been a fix installed in the contact sheet templates that get installed with the update - not sure why the original version was corrupted, but I've left that with the Adobe guys (I submitted a bug report - and they were able to replicate the problem but hadn't fixed it as yet).

When I click import from disc I am asked to choose a disc and then I get this message:
The following photos will not be imported because they are already present in the catalog. To see these photos in the catalog select 'Show in Library' (the import will be canceled).
This is followed by a long list of images. If I click 'Show in Library' I can see all the images with the same filename. And then they start to automatically write over those images with images from the disc. However they keep the same metadata and keywords from the previous images. If I click on Import and deselect the "don't reimport suspected duplicates" box, it imports only the images that don't share filenames and none of the images that do.
Is there a way of setting the "Don't reimport suspected duplicates" box in preferences?

Viewer won't output to NTSC monitor in FCP5.1

Hello!
I was used to being able to view my clips in the viewer on my ntsc monitor in HD, since upgrading to FCPStudio5.1.1, I can't seem to find an option for this, the manual mentions none, and a search provided no answer related to the viewer. I am able to watch the timeline just fine on my ntsc monitor.
Is this a new change with FCP5?
Thanks!

I am connected to a Sony mediaconverter via firewire.
It connects to my tv monitor. External video is set to all frames. After refreshing a/v devices, the viewer will now output to the screen when using "gang" setting. If I use sync off, I get current frame its stopped on. Open gives nothing. Is there a way to make gang the default so I don't have to set it for each clip?
Thanks

RH7 project upgraded to RH8 won't output .epub

I want to make a project available as an epub edition. I've upgraded to RH8 and imported the epub generator script and the zip programme. When I open my project (which was created in RH7) I upgrade it so it will work in RH8. I run the script and generate an epub file but on that is only 560kb big, which seems small for my project. If I try to open it it crashes Adobe Digital Editions.
I can create a new test project of a few pages and get this to work, so it is clearly not the installation but the project that is the problem.
My question is, how do I find out what is causing the conversion to fail? My project is quite complex with lots of images, footnotes, internal links and pop-ups so I don't really want to have to recreate the whole thing in RH8.
Thanks in advance for any advice.

That's what we do best, here...send people away to rethink!
As you rethink the project, you might reconsider tailoring the content for epub so that it could actually be quite useful for those users viewing on a smaller screen.
Actually, this rethinking could be a beneficial two-way street: the epub formatting might prompt you to reformat across the board, thereby producing a leaner primary output. Think about it. As I like to say about extensive DHTML & JavaScript elements: just because you can, doesn't mean you should.
Good luck,
Leon

IPhone 4 Won't Output Audio, No Airplay

My iPhone4 (OS 7.1.2) works fine, but has essentially become a brick to external devices. Music will not play through headphones, the phone no longer outputs audio to my car stereo via USB or Bluetooth, and the AirPlay icon has disappeared from the video player (yes, my Apple TV is on the same wi-fi connection). In my car, the USB screen says "Unreadable" and the Bluetooth screen doesn't even acknowledge my phone (which is discoverable).
All of this started happening under curious circumstances. Up until a few weeks ago, my phone's loudspeaker hadn't been working for a while. The ringtone worked, but no other audio worked. It was like the phone thought I had headphones plugged in. All of a sudden, the loudspeaker started working--I have no idea why--and at that time, I started experiencing the problem I'm describing here.
They sure seem related. Any tips from the community?

Okay - other things I would try is different USB cables and restoring on another computer if possible.
If no joy with either of those, make an appointment at an Apple store near you and bring it in to be evaluated. It may have a hardware problem and will need to be replaced.

It worked from the command line; there was an extra class in the folder called "Test" which the IDE defaulted to for some reason. Thanks, I knew it was something stupid :)

My FCE won't output video

My FCE just recently started to do this. I have my system running through a midi interface which is connected to montiors (speakers) in my studio. Now I can't get my FCE audio to come out of my speakers. I can hear evertyhing wlse including itunes and the bleeps when I raise and lower the volume on my Mac. As of right now the audio is going to my DV camcorder which is connected to my TV monitor. I can hear the sound through the TV but when I try to switch it to "Canvas playback" it won't switch over though it says is has? Help!!!

What happens when you try?
