I am running firmware V 2.2 (yes,2.2) and dexter mod 1.3 though it says 1.2
Any help would be appreciatedll

I had this happen also, it is mostlikely the tv set, it wouldn't work correctly when i plugged it into my 2006 27" olevia tv, but worked correctly on my newer tv. so im guessing it is either:
1.) the tv set
2.) the cable you are using
so to verify you need to try changing the cable or tv set.

HDMI Output Compatibility Testing

I updated my B60 U.S. Transformer with the Android 3.2 OTA update and decided to do some HDMI-output compatibility testing.
I used the following:
15-foot HDMI cable: http://www.monoprice.com/products/p...=10240&cs_id=1024009&p_id=4959&seq=1&format=2
Mini-HDMI-to-HDMI adapter: http://www.monoprice.com/products/p...=10419&cs_id=1041909&p_id=3653&seq=1&format=2
Here are my results:
Sony BRAVIA KDL-46Z4100 (1080p) - the 3.2 OTA update makes the Transformer work perfectly on this 1080p set. It changes its resolution to 1280x720, and then the BRAVIA picks up the 720p signal and displays the cloned output with no issues and no need to make any screen position adjustments on the HDTV side. No sound problems as the Transformer sends the audio output to the HDTV set speakers.
Sony BRAVIA KDL-40S300 (720p) - there is a an overscan display issue with this BRAVIA where a bit of each side is cut off on the HDTV. This BRAVIA doesn't have detailed enough controls to scale back the output display to make everything fit properly. It's not terrible, but it's not ideal looking either. No sound problems as the Transformer sends the audio output to the HDTV set speakers.
Westinghouse TX-42F430S (1080p) - the 3.2 OTA update makes the Transformer work perfectly on this 1080p set. It changes its resolution to 1280x720, and then the Westinghouse picks up the 720p signal and displays the cloned output with no issues and no need to make any screen position adjustments on the HDTV side. No sound problems as the Transformer sends the audio output to the HDTV set speakers.
Acer H233H (1080p) - the 3.2 OTA update makes the Transformer work perfectly on this 1080p LCD computer monitor. It changes its resolution to 1280x720, and then the Acer picks up the 720p signal and displays the cloned output with no issues and no need to make any screen position adjustments on the monitor side. No sound problems as the Transformer sends the audio output to the monitor's built-in speakers.
Sony VAIO VGC-RT150Y - this is actually a desktop all-in-one computer system that happens to have an HDMI input. The Transformer changes its resolution to 1280x720, and then the VAIO picks up the 720p signal and displays the cloned output centered on its 1920x1200 LCD panel. No sound problems as the Transformer sends the audio output to the computer's speakers.
I hope this is of use for some of you out there.
why would you use a hdmi cable then an adapter and instead a actual mini hdmi cable
heres what im using http://www.monoprice.com/products/p..._id=1024201&p_id=3645&seq=1&format=4#feedback
and the 15 foot version http://www.monoprice.com/products/p...=10242&cs_id=1024201&p_id=7649&seq=1&format=2

I bought my 15-foot cable and the adapter some time ago before Monoprice started selling the straight cables that don't need adapters.
Anyway, I rarely connect anything with a mini- or micro-HDMI output, so it makes more sense for me to use standard HDMI (A) cables and then have adapters for when I need them.
More TV's
Thank you for this thread!
Now, are you guys going with your mini-HDMI cable to TV stores to try out HDMI-out compatibility? Thinking I could do that
I have a Samsung LE37xxx, hope it will work, would be kinky!
On another note, you may have to upgrade the TV's firmware because the newer ones (from few years back already) with USB etc. should be upgradeable...
I had a HDMI to mini HDMI adaptor that I bought off ebay however it did not work. I tried it on several different TV's and different cables and a receiver. Due to time constraints I bought a new replacement adaptor from Jaycar - tried it out and worked on two different Panasonic TV's. There were some overscan issues but I didn't have time to confirm if that was just a setting on the TV. I travel a lot for work hence the adaptor is better - don't want to carry the whole cable. If I am in a hotel with a TV with HDMI there is a good chance it will have a HDMI cable plugged into it that I can use.

[Q] No HDMI output to LG 42LD420 tv!

Hello!
Just got my Nexus 10 and I tried to connect the Mirco-HDMI out to my LG 42LD420 tv.
However, screen is all black and nothing happens. When I connect to my new PC screen HDMI port the image is mirrored instantly and it just works...
So I guess theres some new standards in Micro-HDMI that my TV doesn't support?
Just wanna clear this problem by making sure its my tv. And btw, other devices works just fine on the tv HDMI port...
Thanks for any info.
Simon
Whenever HDMI has problems it's usually HDCP that is the culprit.
Thanks! Googled some about it and I realize the problem New TV then I guess or try with some adapters to analog input...
I just ran into this the other day myself with a Samsung TV. I thought maybe it was the TV was only capable of 720p or something...
I'd get sound through from the N10, no picture though.
Also tried an MHL cable with my GNex and nothing as well.
Both devices work no problem on either of my PC monitors, and the PS3 has no problem with that cable/port on the TV.
Are there any workarounds?
My quick search indicates that it's possible that it can be cable specific? ie. Will work for some devices but not others? Does that even make sense?

[Q] No sound through HDMI

I have a Tegra Note 7 and I cannot get the sound to work through HDMI. I connect the tablet to the TV using a micro HDMI cable and the video is fine, but there is no audio. Any solutions for this? Tablet is stock and rooted.

That's weird since mine has always worked fine, and there weren't any special settings to change or anything. I will say that the micro-HDMI port is kinda awful, and if the cable is wiggled at all, the signal cuts out, sometimes just the audio. You may want to troubleshoot by trying another cable and seeing if you have the same problem as well as trying this cable on another device with a micro-HDMI output, if any of that is an option.

MHL

I gather the Zenfone 2 has MHL capability - high definition video and audio (up to 7 channels) output to HDMI via a USB MHL cable/adapter. Has anyone tried connecting to a TV by this method?

GSMArena says that it did have MHL, but everyone who has tried had not gotten it to work, so I'd say it doesn't have it.

Good job I didn't buy an HML adapter I saw yesterday then
I tried to compile in Moorefield's HDMI into my kernel for fun the other day; not so great.
Phone booted up, but said that there was an hdmi connection ( without connecting anything ) and started overheating fast.
I'm guessing that there might be an hdmi connection on the board somewhere that connects to the microUSB bus, but it's soldered/jumpered over.

I think, it's full-featured HDMI connector reserved on SoC (in case if used in Android TV dongle), not MHL.
There is Intel WiDi wifi display service integrated in the Rom. How can we use that for wireless display to a pc or android/smart tv?
Mhl didn't work, tested and asked in zentalk, online chat support and in xda..
But i seen an apk with name hdmi don't know what it is for

Mojo Mad Catz - No sound hdmi cable

I just bought Mojo Mad Catz and no sound, I have connected 3-wire and even a hdmi hdmi 2.0 and not heard on my TV PanasonicTx-40cx300e 4k Uhd 200Hz USB. Connect it to a monitor with hdmi that came in the box and it looked nor sounded but if it works hdmi 2.0 cable with both the video and audio. I tried to upgrade Mad Catz Mojo from settings but check the update tells me to try again later. Not if the problem is Mojo or my TV. Any solution?
Thanks
Did you try headphones in the headphone jack?

If and works perfectly, also tried it with speakers with an rca cable and works. But I do not get it to work on my Panasonic TV with hdmi or the rca cable. I have a multimedia player connected to the PanasonicTV and audio works well. The truth which is not the problem.
I don't know if it will help or not, but you might try a custom ROM. There are three available (thanks to @Unjustified Dev), check the development section.

I do not get solved, so I had to plug in my monitor. Bad luck because he wanted to take advantage of the TV is 4k.
