I've got a MacBook pro 15' running 10.6.6. I want to use an external monitor for my graphic design work running Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing.

I've got a MacBook Pro 15' running 10.6.6. I want to use an external monitor for my graphic design work using Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing. I also tried a Mini Display to VGA lead and that wasn't much better. I tried all variations of resolutions in System prefs - Displays but nothing helped. Am I getting something wrong? Thanks all.

In addition to pixel density, you are up against the translation driver card in the TV.
If you read the fine print of computer-resolution-capability in the TV user guide, you will see a chart as tall as the manual page. At the top is the smallest resolution capable, at the bottom is the full use of the 1080p in the TV.
Mac falls into the top 25% of the page, maxing out at 1366x768 often. This is because the TV control card is expected to do too much of the work, but is not designed for computer-monitor processing.
I looked at the resolution charts on 2 TVs before deciding to buy a 1080p LCD monitor that has a TV interface/connector. Computer monitor first, TV second. But the thing is only 27 in. Good thing TV is not as important to me as it is to others.

Retina mbp not recognizing display through hdmi

I have been connecting my new mbp to my tv for weeks and have not had any problems. Yesterday, I went to connect it through my hdmi and my computer is no longer recognizing that my tv is connected. It switches modes and configures my desktop like I have the external hooked up (I can drag things off my laptop display) but it is not sending a signal to the tv. I have switched out cables, tried a different TV and searched online. Why is this all of a sudden happening after weeks of normal function? Is it related to a software update?? very frustrated...

You should also ask this in the MacBook Pro forum. This is the forum for the white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

No sound through HDMI alternative solution

If you are not able to get sound through your TV through HDMI and have tried all the System Preferences/Audio MIDI steps detailed on here in other threads but nothing works, try just shutting down all running apps.
I had to Force Quit Spotify, Viber, Skype - when I shut down iTunes, the sound from Firefox started coming through the TV. I have since been able to reopen Spotify and play it through the TV too.
I'm not sure why these apps would interfere with the HDMI sound transmission, perhaps more technically inclined people can answer this but it turned out to be a straightforward solution that I didn't find on here (although maybe I just didn't look hard enough!).

Is it an occasional problem or is it that you have never had the hdmi audio output working with windows 7 Ultimate? If it has never worked, is hdmi even listed under playback devices when you right-click the speaker icon in the notification area and click playback devices?

Sound through hdmi to my tv works but not when watching video online like 4OD

the sound through hdmi to my tv works with music and videos I have downloaded, but not when watching video online like 4OD and youtube.
How can I get it to work?

Ok so I happened to figure it out while on the phone to apple support. Even though the guy was very nice, I think I knew more than him! He was explaining very basic resolution principles I played about. I had the second option in displays resolution. All I did was unplug the HDMI cable, click on 'best for display' then plugged the HDMI in and my resolution on the normal monitor changed to the normal blue, then went black momentarily and then changed to a strange resolution but another window appeared that said SONY BRAVIA HDMI at the top! Hey presto! Don't know why it didn't do it yesterday - I probably left the HDMI cable in or something! Oh well. Problem solved!

You could try updating your apple TV and then restarting it. Bit of a guess.

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.

Imac HDMI doesn't display to TV through HDMI

imac HDMI doesn't display to TV through HDMI switch

hdmi switches are notorious for not working with most computers and appletv's and well most things with hdmi ports really

I cannot get audio through my TV using HDMI lead it has worked previously but on the settings tab the option to use HDMI for output has disappeared

As above I have a MacBook Pro and pretty new Samsung TV... i bought a HDMI lead from apple shop connected it and was able to choose HDMI lead as sound output.... but i cannot do it any more nothing has changed cable has not even been unpluged but the option within settings has disappeared.... I have tried the basics turn everything off and on again close all apps disconnect and reconnect leads..... any help would be brilliant

The problem is not solved by something that simple unfortunately ! I have discovered that if I boot up the laptop with the hdmi cable connected to the tv it works, but if not, same issue. Have read everything everywhere I can to see if the issue happens for anyone else, seems mine is an odd one. May reinstall FF to see if that cures.

What cable do I need to be able to watch a movie through my regular LCD TV?

what cable do I need to be able to watch a movie through my regular LCD TV?
I've haven't got any of the other cables for my Retina display, and I've tried connecting my Mac to my TV via HDMI cable, but no sound comes out and apprently I need another cable...?

Your HDMI output port should be carrying the audio signal to your television. If it's not, you can use a Thunderbolt->HDMI adapter that does carry sound, such as this one from Monoprice.

Hd Audio Through Hdmi Satellite L755-S5246

Hello,
I'm wondering if there is a way of getting full HD audio from The HDMI port on my Satellite L755-S5246. I have Gone through the sound options and tried to configure it to Surround Sound, But the only option is stereo. Is there a way to change this? According to device manger I have The CONEXANT audio driver for the speakers that are in the laptop and it is up to date. I tried to install the NVIDIA Audio driver, Because To my understanding it controls audio through the hdmi but When I tried to Install it comes up with an error message saying it cannot locate the drivers to install. Leaving me to believe that the NVIDIA driver isn't supported in my model. When I have My laptop connected to my television, and look at the sound properties, It says it's using the Intel Display Audio Driver for sound. And when I try to configure it under the sound properties on my laptop it's still doesn't list any other option other than stereo.
Question: is there a way getting Hd audio out Through the hdmi connection, Mainly Dolby 5.1 surround sound?
Relevant Information:
Laptop model: Satellite L755-S5246

I can't test this because I don't have your sound card or your TV. But, I think you're playing with the wrong device. And, I apologize in advance if you've already done this. But, you haven't made clear what you've already done on the TV side of things.
With your laptop and your TV both turned on, with the HDMI cable connecting them, select as its video input the correct HDMI port that you've plugged the HDMI cable into on the TV, you then need to use your TV remote control to enter the TV's Menu, then select 'Audio Menu', use the up down arrows and select 'SRS TruSurround HD', turn it 'On'. If you want to try just audio (that is listen to mp3 files with no video) again, enter the 'Audio Menu', select 'Audio Only', turn this feature 'On', when you want to watch video turn off 'Audio Only'.
You can see the instructions for this staring on page 26 (Adobe Reader page 28) or your TV's user's guide. But, if you have already done all of the above, then sound coming out of your laptop, through the HDMI into your TV, is as good as it's going to get.
You have a Conexant Sound card & a Intel Video/Display card in your laptop. You have no nVidia devices at all, so no nVidia driver will ever load on your laptop. Because you have a Intel Video/Display card, and the HDMI port is mainly for watching DVDs, etc, on an external TV/monitor, the display card handles the HDMI audio as well.
Let us know what happens. Good luck.

Mini display to hdmi adapter problem

Hi,
When I connected my mini display to hdmi adapter to hdmi, and hdmi cable to my ASUS PA238QR monitor, my early 2011 MBP 13" detects the monitor, but the monitor shows "hdmi no signal".
I tried unplugging everything, including the adapter and hdmi, but to no avail. I tried putting my computer to sleep, and waking it up, still, nothing seemed to be the cause of the problem.
I read through some old discussion on this issue, and nobody seems to have a solid solution besides purchasing another adapter.
I tried booting into win7 and still, the monitor shows "hdmi no signal".
I am 100% sure my monitor and hdmi works becuase when I used other laptops it's fine.
Thus, I'm suspecting it's the mini display to hdmi adapter's problem.
Is there a way I can make sure that my macbook pro is outputting the signal?
Any recommendation or advises are welcomed. Thanks for reading.

If you've an HDMI port on your television, you could always try that.
I've used this adapter from Monoprice successfully - not bad for under $7.
Give your TV a try - if no go, then you'll know that it's an adapter problem.
Good luck,
Clinton

Hello ,
Thanks for using Apple Support Communities.
Please follow the steps below to troubleshoot having no display on the external display.
No video or no signal, image distortion, "snow," or flickering
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.

The Best Mini Display Port HDMI Adapter?

I am looking for recommendations on a good Mini Display Port HDMI Adapter for my Macbook Pro 2011 Sandy Bridge. I have gone through about 4 adapters in the past year due to the adapters become unresponsive after 2 or 3 months. I use my Macbook heavily on external monitors for my work (averaging 7 hours or more a day between various monitors).
I can rule out the HDMI wire itself not being the cause of the problem but the adapters have been a huge miss and drain on cash this year. If anyone who is also a heavy user can point me in the direction of a durable adapter I would be very grateful.

I always recommend monopriice.com for cables and adapters.
Mini DisplayPort | Thunderbolt® to HDMI® Adapter w/ Audio Support
But all these adapters are in the form of "pigtails" and no matter where you get them the strain relief and the cables can fatigue and break from constant bending or pulling (doesn't help your macbook socket any either).
Maybe you should order a bunch. They are cheaper that way at monoprice.
Another possibility might be you trying a mini displayport to HDMI cable. No adapter.
Kanex Mini DisplayPort to HDMI Cable with Audio Support (10 ft.)
But of course you could get about 6 adapters for the price of that one cable!
