Nothing displayed on TV through HDMI.

I have an Acer 4820T with Intel HD 3000 graphics and am trying to use a Sharp LC-37GA8E as a second display. It works in Windows 7 without problems but not in Arch using arandr/xrandr. The TV will change resolution as you try different settings but the screen is blank. Arandr/xrandr does work perfectly with an LG M2262D through HDMI.

Can I connect imac to HDMI and also Surround sound also through HDMI using the thunderbolt sockets via an adaptor into a HDMI?

I want to be able to connect my imac to my TV and Surround Sound, from what I have read the best want of doing this is both via HDMI. Before I go out and buy another adaptor for a second thunderbolt to HDMI I was wondering if this would work? I basically I want to be able to stream videos from Imac to TV with sound coming through surround sound and also when I am on itunes have the music come through the surround sound. At the moment I have an adaptor (thunderbolt to HDMI) which goes into the TV and a optical cable from TV into the surround sound, then I also have a 3.5mm from the imac to the Surround sound, but I find this lacks in quailty. Would upgrading to a HDMI work and be better ? Should I also look into an optical cable though I dont see how to connect this to the imac?

OK. From what I can tell here, the Sony HT-SF2000 has 3 HDMI inputs & one HDMI output, so the simplest hookup would be to connect the iMac to one of the the Sony's HDMI inputs via the Thunderbolt-HDMI adaptor, & connect the Sony's HDMI output to the TV's HDMI input.
Use the Sony like an HDMI input selector for the TV (plugging in your other HDMI devices, if any, to it). Use the HDMI input on it from the iMac for both movie & iTunes sound output, & for TV output for video. (You can even use the TV as a second screen for the iMac.)
If for some reason you want a separate input for the iMac's sound output, you can use the optical input on the Sony for that, with a TOSLINK cable connection to the iMac. You will need either a Mini-TOSLINK adaptor or a TOSLINK to mini-TOSLINK cable to connect to the audio output of the iMac.

How do I get my iMac's HD(Broken display) to function through a Macbook Pro?

I am attempting to use my iMac with an external monitor and I need to allow the second screen to function as my primary screen.
I presently have a Displayport to VGA adaptor (leading to a monitor) connected to my iMac. Then, I have a FireWire spanning the iMac and a Macbook.
When connected via FireWire and accessing the Macbook's HD, I can access many files but cannot change any display settings.
After holding Option at the Macbook's start-up and selecting the iMac's HD, the Macbook displays the Apple symbol with a grey background and does not appear to be loading anything.
The iMac is running OS X 10.6.8 and the Macbook is running 10.8.3.

Yeah, this is going to be a stickler.
If the MB came with 10.7 or later, it won't boot/load/run 10.6
We might be able to edit some plists on the iMac & do something, but without those 2 to test I'm not sure which/what.
Can you find somebody with a 10.6 Mac?

Toshiba Regza does not display PC connected through HDMI

I live in a flatshare in which there is a Toshiba Regza in the living room.
This television is connected to a Virgin Media V Box through an Xbox HDMI cable.
I tried using the same cable to connect the tv to my laptop, which has a HDMI port, but nothing shows up on the screem.
I checked in yhe Nvidia control panel and on the computer's screen settings: the Toshiba-TV is successfully recognized, so why I cannot see anything?
The V Box is usually tuned on the HDMI-1 channel, but all I see there is a blue screen. Same on HDMI-2.
The PC channel is instead black.
Can somebody please help and tell me what I am doing wrong?

What model is the TV?

Dell Venue 11 Pro - doesn't display anything thru dock HDMI

Good day,
After some time functionality related to desktop extension (or rather any output thru dock HDMI) has been broken. I have Dell Venue 7130 MS on warranty.
I refreshed Windows 8 and it didn't help.
Now I can extend desktop only being connected thru built in tablet's micro HDMI. In case of the dock's one - monitor could be detected but nothing shows on. Screen being reset to 1024x768 meanwhile.
Tried 2 docks. Have latest A15 firmware and all docks updates installed.
How I can solve the issue?

Hello,
I've exactly the same problem. I've also the model number K10A001 and the current Firmware 0.41.9, and it is also not possible for me to flash the docking station.
This is also problematic because only one monitor of the two connected monitors works. An this monitor shows only a picture, if it is plugged, after the dockingstation and the Venue 11 Pro has been started.
I think there is maybe an improved flash utility required in order to allow to flash the docking station? If some one had succeeded please respond.
Thank you

Sony KDL-48W600B will not display 1080p signal through HDMI

I just bought that sony KDL-48W600B 1080 tv and want to use it as monitor for my pc.. but the tv only shows pc content if I put the resolution to 720p. When I go higher the tv shows black/blank screen. What should I do to get 1080p output on the TV via hdmi?

make sure the TV is on when you boot the computer. I have had that happen, I am assuming the model supports 1080 mode.

Imac calendar doesn't display Calendar inspector as advertised

Advertized Version
What happens to my inspector I assume get info is the inspector

Take a look in Settings/General/Date & Time.
Is it set to automatic? Is the time zone correct?
If set to automatic, try unsetting it and give it the correct date & time and see if that fixes the problem. It should work "automatically", though, but this will at least narrow down the problem.

HDMI doesn't work, but MDP- DVI- HDMI works

Hello!
I just got my new Mac Mini and tried to connect it to my TV (a Samsung LE22S8) over HDMI, but this doesn't work since the TV reports "unsupported resolution" (it's the TV's native resolution of 1680x1050, where I also checked all frequencies using an external program and they are as written in the manual of the TV).
However when I connect the TV over a Mini Display Port to DVI adapter, and then use a DVI to HDMI adapter (so that the TV is still using the HDMI input) it works fine.
So what's the difference between MDP->DVI->HDMI and HDMI->HDMI (all resolution and pixel frequency settings are identical)? What can I do to get the HDMI->HDMI solution working?

It also appears that there is no conversion when HDMI-video is extracted from DVI, only that the pins are shuffled.
If direct DVI works on that port, then HDMI-video with an adapter should work as well. As I mentioned above, VGA is present on DVI-I ports on a separate set of pins, and VGA working or VGA not working has no bearing on your problem.
If a Mini DisplayPort is involved, the most common issue is that the Mini DisplayPort connector is not inserted firmly enough. It has a lot of pins and you have to press hard to seat it.
Other possibilities are that the resolution you selected is beyond the capability of the display device, or that the adapter is bad.
Is this the stock display card, or one you added later, and what model?

No tv display with thunderbolt to hdmi, no tv display with thunderbolt to hdmi

I just bought a Thunderbolt to HDMI connection cable. It is an apple cable. My Tv just stares back at me in Blue. Does anyone know why the cable is not working or knows how to resolve this. It would be greatly appreciated. Thanks.

Hey DanVanB,
Thank you for visiting Apple Support Communities.
You may find the troubleshooting tips in the "Update your software and firmware" and "No video or no signal, image distortion, 'snow,' or flickering" sections of this article helpful, if you've connected your MacBook Pro to an HDTV but only get sound:

Can i use a hdmi to mini display port cable to use my iMac as external monitor for a windows laptop?

Does anyone know if a hdmi to mini display port cable can be used to link a windows laptop with an 27 inch iMac to use the iMac as an external monitor. Or are there other options to connect my DELL latitude 6430?

Is the 3.5mm-to-optical cable any better than using a standard 3.5mm? I don't know too much about this stuff. My thought process was that if the source of the connection is a 3.5mm jack, does it make a difference using a cable that starts as a 3.5 and converts to optical?
Chances are excellent that if your receiver is less than 20 years old it has an optical input, this is a digital signal which will sound MUCH MUCH better than using an analog 3.5MM to 3.5MM connection. I recommend using the cable suggested or one with the same connections but of a different length if your needs warrant it.

Mac Mini Doesn't Display through Philips Tube HDTV

I have a Philips tube HDTV with a VGA connector in the back, and used the DVI-VGA connector that came with my new Mac Mini to connect. I don't have a computer monitor at home. The TV doesn't display anything.
So then I took the Mac Mini over to a friend's. He has a VGA monitor, and so he ran the Mac Mini through setup and set it to the lowest possible display settings. I came back here, rebooted and plugged it back in; still no display.
Then I tried this:
"First thing to try is to boot the mini into safe mode by holding down the shift key as it boots up. This should allow it to boot, and then give you access to the display preference pane to adjust the settings back to those that worked.
If that doesn't work, try disconnecting the TV, and rebooting the Mac with no display attached. Once it has fully booted and enough time has passed to allow the desktop to be displayed, reconnected the TV. This should force the mini to boot into a low-res mode that works with just about anything, then when you reconnect the display, either cause it to auto-sense the correct resolutions, or give you access to display preferences."
This didn't work either. Any suggestions?

Hi Alan,
Check your TV manual to see what resolutions your VGA/RGB connector on your TV will accept. Being a HDTV it is likely to be from 480p to at least 1080i.
You then set the resolution in your Display preference pane to 640x480 and you should get a picture on your TV. The trick is to set it when you can't see anything! Attaching to another device may not help because the Mac detects that device when you set the Display and will know its not that when attached again to your TV. When attached to your TV it is setting another resolution it thinks will work. It is clearly guessing the wrong screen resolution when you do connect it.
I overcame this situation myself using a VNC client. That requires you to have another computer you can use to control your Mac Mini via VNC. You can then access the Display pane via VNC and set the 640x480 resolution which will work.
For setting 1080i (and the VNC process) please see:
http://www.macosxhints.com/article.php?story=20060319073027371&query=1080i%2BMac %2BMini
I am guessing you can also use an S Video adapter - available from Apple - to connect to an S Video port your TV may also have. That won't help with the VGA connection though.
Hope this helps.

IMac running 10.8.6 doesn't display entire desktop? Reset display to various options and it doesn't display the entire desktop.

iMac running 10.8.6 doesn't display entire desktop? Reset display to various options and it doesn't display the entire desktop. (asking for a friend, not my iMac)

I think you wanted to say 10.6.8. 10.8.6 does not exist.
The first thing I think is that zoom may be enabled. On Mac OS X 10.6.8, a way to disable it is to hold the Control key and scroll down with the mouse or trackpad until you can see the whole display. Another way would be to disable zoom in System Preferences > Universal Access
