[SOLVED] HDMI output not working

I just bought myself a home theater system but can't get my laptop to connect to the reciever.
My laptop is an Asus UX31E with integrated HD 3000 graphics. When I connect a HDMI cable to the reciever (Pioneer VSX-527) it doesn't even detect my laptop. If I go into the Cinnamon/GNOME display settings, it doesn't even show that I'm connected to an external display.
In pavucontrol I'm able to select the HDMI as an output, but it doesn't play any sounds on the reciever (which plays just fine from radio, so at least the speakers are connected correctly).
What to do?
Edit:
And here's the output from xrandr:
HDMI1 disconnected (normal left inverted right x axis y axis)
Solved:
Derp, faulty cable.

Hi:
The only suggestion I can offer would be to try the graphics driver from AMD if you have not already done so.
Your notebook is not supported by HP for W7, and especially not supported for 32 bit operating systems.
http://support.amd.com/en-us/download/mobile?os=Windows%207%20-%2032
As a last resort, try manually installing the W7 x64 graphics driver from your notebook's support and driver page (sp66999).
I explored the driver folder, and there are 32 bit drivers included in that file.

HDMI output not working since firmware upgrade

I would appreciate troubleshooting tips for getting the HDMI output to work. I just tried it recently for the first time in a long while, approximately 4 weeks after doing the firmware update to 2.2. When I did it before, plugging in the HDMI cable would automatically start output to my HD TV. Now that is no longer the case. Changing the HDMI output from "Auto" to "720p" does not make a difference either.
Otherwise, everything works well and I've been satisfied with my Creative 7 to date. I have installed several apps so it could be that there is a conflict and nothing related to the firmware upgrade.
Any troubleshooting suggestions would be appreciated.

Well I've received my refurbished device for about a week now. The HDMI still doesn't work either with Zii Video or a 3rd party app MoboPlayer. ?I am tempted to reinstall the firmware upgrade again. Is it ok to try this or is it only a one time attempt?
Perhaps this should be a separate thread but are any of the "Phone 2 SD" apps compatible with the Ziio 7? Whenever I use the "Move to SD card" option, there is still no program moved to the external SD card. ?I have a Ziio 7 with 6 GB of memory as well as a 6GB micro SD card. ?My memory settings are:
- SD Card: total space - 5.43GB; Available space - 5.43GB
- Device media storage: Total space - 2.48GB; Available Space - 2.3 GB
- System storage: Total Space - .97 GB; Available space - .59GB
In Settings>Applications>Manage Applications, the "On SD Card" tab lists several programs lists several apps but none of them are actually on the external SD card.

E520 - HDMI Output not working on Samsung TV - although works on other devices

Laptop does not recognise TV
I know there are a number of threads with similar questions, I have been through a number of them, however have not come across a solution that works.
I have a ThinkPad E520 running Windows 8.1 Enterprise Edition x64
The Laptop has two Graphics adapters
Intel HD Graphics 3000 (Drive - 9.17.10.2867) - I have recently reverted back from the latest Intel driver to the latest Lenovo
AMD Radeon 6600M and 6700M Series (Driver - 13.251.9001.1001) - latest on AMD website
The TV is a Samsung 5 Series 5200 58 inch
We use the TV at work for presentations and demo etc
At my desk extend my desktop to a Philips monitor via HDMI and have no problems at all, I also using with HD TV at home, so HDMI port is ok. Other laptops us the TV fine, so nothing wrong there either.
Things I have tried
The obvious 'Windows key + P' extended, duplicated, restarted and tried again
Did the same as above using screen resolution page - TV is not detected, tried hitting detect - nothing
Disabling AMD adapter
Uninstalling Intel HD and reinstalling latest INTEL drivers with HDMI output plugged in
Uninstalling Intel HD and reinstalling latest LENOVO drivers with HDMI output plugged in (as suggested in other posts)
Tried different HDMI cables, using HDMI input 1 and 2 in the TV
Initially you may think its the TV, however we have a number of Lenovo E530's they all work, the problem only exists with the E520's with the switchable graphics.
Any help would be greatly appreciated.

HDMI output not working with AT 200 under ICS

Hello,
I connected the HDMI output to a Sony KDL 32 E 5500. It simply does not work.
The same TV HDMI input works fine with a DVD player.
The AT 200 tablet is under ICS (upgrade in France).
I tried both HDMI configurations : full screen and video window.
Should I send it back for repair ?

Hi
There are two outputs: Mirror and video area only.
Mirror:
External device copies the image on the tablet screen
Video area only:
The external display device shows the playback when open a multimedia
But You should firstly check the Android Settings:
Under the option Screen you will find the option HDMIO video mode
Tap this to switch between the HDMI video output mode.
You could also try to connect the HDMI device under following conditions:
- Tablet is turned on
- Tablet is completely turned off
- when you connect TV or external monitor to HDMI port, then display output is set to HDMI
- when you plug and replug the cable, wait at least 5 sec before you replug the HDMI cable.

Any driver beyond this does not work with HMDI output.
Worked for me after 3 months of trying anyway!

When you press FN+F5 key combination while notebook is not connected with HDMI cable, you will see one option (LCD) only. When you connect HDMI cable can you see other additional options like LCD, LCD+HDMI, HDMI and so on?
Please be also sure that right HDMI port on your TV is enabled.

HDMI Output Not Working on Lenovo B540

Yesterday morning the HDMI output on the back of our Lenovo B540 stopped working all of a sudden. I have a projector as a secondary monitor that I use for media applications which connects via a SVGA to HDMI converter which has worked flawlessly for months until yesterday. My first inclination was the converter but after some troubleshooting I have determined that the issue is somewhere in the Lenovo AIO system. Below are the steps I followed to make my determination:
1. Tried connecting Lenovo to another known-good monitor and nothing. The display property picks up the monitor's attributes like make and model and even resolution but no display.
2. Plugged projector into another computer WITHOUT converter and it WORKED.
3. Plugged in project into the same computer that I used in step 2 above WITH converter and it still WORKED.
Steps taken to resolve (without success yet):
1. Updated Intel HD Graphics display driver to 10.18
2. Installed latest graphics chipset update from another forum post I found suggesting that might be the issue.
3. Changing "Source Select" from bottom right hand corner of system (icon with arrows forming circle) but it ONLY shows "PC" option. Not sure if that's the issue or not, but wanted to mention it.
My next step is to completely uninstall the display driver and try seeing if second monitor shows display.
My last step which I would like to avoid if all possible is a factory reset as I have many applications installed that I would like to avoid reinstalling if at all possible.
Any further assistance with this issue would be greatly appreciated. I feel like it's a driver/configuration issue, but I'm not finding it yet.

I wanted to reply that I just discovered that my Lenovo AIO no longer likes my converter. I'm not sure why as I have proven that it works by using it on another device. The other device is a laptop running Windows 7 Pro.
On a haunch, I plugged in my HDMI TV which has a native HDMI connection and it WORKED. So, I suppose I'm back to the drawing board and this is indeed not a Lenovo hardware issue.
Does anyone know of any issues with using a HDMI to VGA converter on a Lenovo B540 AIO? Link below:
http://www.startech.com/AV/Converters/Video/HDMI-to-VGA-Adapter-Converter-for-Desktop-PC-Laptop-Ultr...
I have the one above but I just noticed there is a HD2VGAE which I'm not sure what the difference is.
Thanks!

Satellite C855D-S5237 Laptop HDMI Output Not Working

Hi, I have a Toshiba Satellite C855D-S5237 Laptop and the HDMI Output is no longer working on my Toshiba TV. The TV does not recognize that anything is connected and the laptop doesn't recognize the TV as a display option.

[SOLVED] HDMI audio not working (worked in Ubuntu)

hi there,
I have very new hardware (Intel Core i5 2500, using the internal GPU) and already knew that it would probably take me a while to get everything working (especially the GPU). I first tried Ubuntu 11.04 Alpha with the xorg-edgers ppa, which already supported the new GPU, including 3D acceleration... unfortunately, it made my X server crash about every 15 minutes. Having heard about ArchLinux before I thought I should give it a try. Turned out the packages that I need for my GPU are only available in testing (xf86-video-intel 2.14, Mesa 7.10, Kernel 2.6.37), so I'm running on the testing repository right now. But I gotta say that I'm pretty impressed by ArchLinux, Compiz is working perfectly smooth and the whole system feels way faster than Ubuntu.
Now regarding my problem, I can't get my HDMI audio to work. Usually I would have said to myself "well, ALSA doesn't support it yet, I guess I'm gonna have to wait" . But the reason I'm writing this thread anyway is that it was working fine in Ubuntu 11.04 Alpha. In Ubuntu, I could use the alsa device hdmi:CARD=PCH,DEV=2 for HDMI audio. The strange thing is, this device doesn't exist on my ArchLinux system. Here is my "aplay -L" output.

In Ubuntu, I also had hdmi:CARD=PCH,DEV=1 and hdmi:CARD=PCH,DEV=2. So my question is, why are those missing on my system? Kernel and ALSA are the same version (2.6.37 / 1.0.23)!? I also already downloaded a Daily Snapshot of ALSA and did a ./configure, make, sudo make install - still no luck. And btw, DEV=0 outputs sound through my default speakers...

any help would be appreciated..
...and really thanks to the whole community, my system is stable as never before and the ArchLinux Wiki is probaby the first Linux Wiki that actually helped me solve my problems.

00-08 is the missing device I was talking about, aplay -L doesn't list it, but it's there. Anyway, I can use plughw:0,8 to use HDMI audio and it works fine, although I'm still confused about the difference betwenn plughw:x,x and hdmi:CARD=PCH,DEV=X...

HDMI Output not work on Encore Tablet

Hi guys,
First post and a new user of the Toshiba Encore.
Some background - I had a faulty Encore previously, but it would connect to my HDMI screen. The replacement, now 3 weeks old, works perfectly, except yesterday I tried HDMI out for sound (to an HDMI amplifier) but nothing. And then I decided to see if it would do HDMI out video - and nothing.
I plugged in the same cable that worked on the faulty tablet and to the same screen. I hit the devices charm and duplicated (and even tried extending) the screen. Nothing. I tried both HDMI ports on the screen. Nothing.
The last (faulty) tablet would make the sound that a new device was installed when I plugged HDMI in. This one makes no sounds. It's like the HDMI port isn't connected at all.
What advice would you give? I have downloaded all BIOS and Windows updates. I used the Intel update tool and everything is current. So what could I try to troubleshoot to get this to go?
Will happily provide more info if needed.
Cheers

This HDMI connection still does not work. It only shows on the TV not on both. I have spoken to Toshiba Software and they have a fix which are some special tools at a one off charge of £84. They say the problem is to do with the HDMI only sending at 30 Hz and the TV being at 60Hz. They also say the fix will provide mirroring as the resolution of the TV and Encore are not compatible. As I only paid £177 for Encore I am reluctant to pay such a high amount. They also advised that you must be connected with the mains adaptor because the battery is not powerful enough to sustain the signal. My laptop works fine and I have a new HDMI cable for Encore.
Any further thoughts?

HDMI output not working after Windows 8.1 update

I am using an Envy TouchSmart 15 and I have just run an update of Windows 8.1 based on the system auto update (it ran 5 updates). Prior to the update, I used a 27" monitor as the main screen and this was connected via the HDMI port. Right after the update, the system doesn't seem to recognise the HDMI port anymore and it goes back to using the Envy laptop screen as the main screen. I changed the HDMI cable but it made no difference. I subsequently connected another laptop to the 27" monitor via HDMI and it worked fine. So it appears both the monitor and the HDMI cable are fine. Please can you help ?

Hey yawbus,
I would first like to welcome you to the HP Forums!
Thank you for sharing the troubleshooting steps that you have done already, and I will say you are correct that the issue is not with the HDMI Cable, or the 27" monitor. From what you have described in your post, it does sound as though the issue is with the drivers, possibly a conflict.
I would like to start of with installing the original video drivers that came with your notebook. I have included the document 'Using Recovery Manager to Restore Software and Drivers (Windows 8)'. Please follow through the steps for just reinstalling the original video drivers. After the original drivers have been installed, please restart your computer.
Now once the computer has restarted, you will need to install any updates that are available for both HP, and Windows. You can install both of these through the HP Support Assistant. I have included the document 'Using HP Support Assistant (Windows 8)'. Scroll down the page about halfway, and you should see an option for Updates and tune-ups. Please follow the options for HP updates, and Windows updates.
If you are still experiencing the same issue after the above troubleshooting steps, please let me know the full model number of your Envy TouchSmart 15. I have included the document 'Guide to finding your product number'. As well, please confirm the current version of Windows that you are running. If you need assistance in finding the version, I have included the document 'Which Windows operating system am I running?'.
Looking forward to your reply!

HDMI output not working after 1.0.8.6067 update on sharp LCD TV's

Have three TV's two of which are Sharps Aquos and the other is a Samsung. After updating to 1.0.8.6067 the Playbook cannot detect the two Sharps(each different model #'s) . I have three different cables that worked fine before the update and all three cables still work perfectly with the Samsung TV. This issue has been giving me trouble from when i got the device. I even sent the unit back to RIM and of course it was no fault found. About a month ago it suddenly started to work on the Sharps. i've been using the playbook daily on these TV's without incident until the latest software update. It now only works on the Samsung. Obviously something is going on with the playbook HDMI software driver. RIM support was unable to get it working reliable during my 3 month support window. Of course it started to work on the last day of my support but the recent update has put me back to square one. Any suggestions?
Tony

I have not had any issue with any brand TV yet
I dont remember if I tried a sharp on not. I do know that teh several Samasung ones worked fine.
