Hi there, I've seen some issues reported with wifi and HDMI, however, none that seem to match the symptoms I've got. Famous last words...
I have two Asus eeePad Transformers. One is at 3.2 and the other recently updated to 3.2.1
I have a mini-HDMi to HDmi cable plugged into my HP monitor via an HDMi hub as follows:
- initially a direct attach to the monitor gets a cable fault on the monitor
- via the hub and nothing else activated, HDMI "bounces" between connected and not
- Powering on my DVD player into the hub, gets HDMI working a treat.
From looking at other posts, maybe I need a different cable, anyway that;s not the issue here, just history.
One of my TF101's was updated to 3.2.1 Now that device has issues with HDMI connected. It took me ages to debug this too:
- If HDMI cable in use, WiFi "stalls/stops". e.g. web pages don't load, WiFianalyser shows no signals etc.
- When screen saver kicks in and HDMI turns off web page loads complete
Other TF101 on 3.2 is still fine.
TF101 at level 3.2.1 was connected to the charger with no difference.
Any help greatly appreciated as I have to fiddle quite a lot to use HDMI now
No problem on my TF with WiFi when HDMI connected. I watch Netflix all the time while connected to TV via HDMI cable. I have a B60 model on 3.2.1 .
Thanks nonpaq, seems like I need to know more about the level of support with the cable etc. Good to know it's not a solid problem.
Problem with hdmi and wifi
hello,
i have same isuue when hdmi connected.... wifi go away, not all the time, but its happen specially when whatch youtube movies .....
I have the same problem. I Use the revolver-rom (3.7).
I had the same problem , and i had change the canal of the wifi , and all ok
I'm on the stock ROM and have the same issue on 3.2.1. Seems to be intermittent - Works some of the time. I have noticed that the Wi-Fi signal always looks strong but web pages won't load either. Other posts seem to suggest that you need a 1.3 HDMI cable. I have a 1.3a (whatever that means)
Hdmi disables wifi
Same here. Have a Tf101. Updated to ICS two weeks ago. A week ago i bought new headphones noticed the left earphone not working. Tested with other headseats same issue. Did a factory reset, same issue. This week whenever i plug in the HDMI the internet connection slows to unusable.
I think its all hardware related. Time to send it back to the manufacturer and pick up that IPAD 2 I was offered today.

Just a heads up - I just got a dock care of one of the XDA members here (their donation to me - and thank you, btw). This is the zPad dock. My tests were all done on TnT Lite 3.1.2.
HDMI "just works" - plug it in and the output will show up on your HDMI output (in my case, it was a TV). Sound is also passed through, but seems to have a slight lag.
Ethernet "just works" - plug it in and the device is on the network. I'm not sure if there's a way to disable it, other than pulling the Ethernet port out.
Finally, the USB port also seems to work - I tested it with my USB keyboard. So, it seems like the TnT devs already built the kernel / UI with the dock in mind. I haven't tested the VEGAn build, yet.
EDIT: Just tested VEGAn 1.0.0 beta 4. USB / Ethernet / HDMI all seem to work. In the case of VEGAn, I actually tested HDMI off my PC monitor (which happens to have some cheapo speakers on them) and there's no audio lag. Perhaps it's something device specific, or cable specific.
EDIT2: Ethernet is now failing on VEGAn. I guess I spoke too soon.
Thanks for the tests. As for Ethernet, I wonder if u need to disable the wifi on the gtab when using the Ethernet on the dock?

More Ethernet testing - it seems that it's a DNS issue of some sort. IP ICMP tests definitely work.
Does HDMI out work without the dock being powered?

Yes, LAN is working. It appears you must boot Tablet with LAN connected and tablet in doc for it to recognize it.... I say recognize it, but when you launch browser you get a notice box that says page can not be displayed due to no connection.. but you just check ok, the box goes away and you are online.

HDMI and LAN require the doc to be powered.
Can we get a link to the dock you bought?
Thanks for the confirmation! Looks like I'm going to return this and get the elocity just for that HDMI port...

Interesting that I can use the internet, I can retrieve my comcast email, but I could not run my exchange email. When I would refresh it, it just sat idle. when I resumed my wifi connection, it immediately downloaded my messages.
The LAN does need some work here by the Devs for sure. It also stopped for some reason and I had to reboot to reconnect it.
So connecting my TF to a bravia w5500 does noting but dmesg shows hdmi handshake error.
In simple words the TF cant get a edid to know what kind of hardware is connected.
But who is ad fault here, my sony bravia or TF .
As note i only have problems with the TF every thing els is working with my bravia.
And i have a 1.4 cable (direct)
any one have same problems and dmesg ( i2c error reading edid )
Edit , a 1.3 cable does not fix it
Try plugging it to another HDMI devices and lets see what you get in dmesg.
I should try my HDMI port too to see how it works.

tested with some tv's all working
All bravia w5500 do not work , so whats up with this ( dont know if more bravia have this problems )
Try changing HDMI setup options of your TV, from a quick glance at the user manual of your TV, I can see there are lots of options for HDMI, some are specific to connecting Sony devices, try turning those off. My TV doesn't have that many HDMI options and it worked straight away.
Works fine with my Visio. I need to adjust the HDMI scaling on my TV but other than that, it's great!
Seems to work with my Bravia HX800.
Whats this HDMI scaling ?
Tested it last night. Connected my TF to my yamaha receiver's hdmi port. My only complaint is the audio volume is low and i have to crank up the receiver.
tf101 and Sony Bravia KDL 40 W 5500
Yes i have the configuration Sony Bravia KDL 40 W5500 and transformer, but with
the new cable that i receive today from ebay, the screen of my tv is black grrrrrr
but oon bravia near the icon hdmi, i can see an blue arrow just when i plug my tf.
this arrow disappear when i unplug the tf, then this cable is good but the screen is
always black !!!!!
somebody have a solution ?
Your problem is basically what this thread turned into:
http://forum.xda-developers.com/showthread.php?t=1111672
We're looking into it but it looks like it may be a problem in the kernel.
Well I have Brawia W5500 and also my HDMI does not work...
I have an off brand Auria tv but it works great with all my devices. I can't get hdmi out through my receiver or directly to the TV. The TF shows the mini hdmi connected and blacks the screen. I see on another thread there is a known issue with some TVs and ASUS has acknowledged it.
I have a Z4500, the HDMI from the TF works. But the picture is not great quality, the upscaling of the TF from SD to 720p is very poor.
Also trying to find out if HDMI supports dual display output? has anyone had any luck?
So still nothing?
Never used HDMI out on android so might be missing something simple. Bought this cable from Monoprice (http://www.monoprice.com/Product?c_id=102&cp_id=10253&cs_id=1025301&p_id=7557&seq=1&format=2) when i connect it to my Samsung TV it shows something is connected to the port, but states "No Signal". I tried using TechFusiin and Cromi-KK (latest of each) and opened Gallery to try and cast pictures or video but no dice. I have also restarted the tablet and TV in various orders.
What do i need to do to make this work? Or should I just return the cable?
Hey everyone.
I need some help with an HDMI- DVI problem on my MK808B Plus
Goal:
Connect my Android Mini-TV (MK808B Plus) to a specific PC monitor.
Problem:
Monitor has a resolution of 1440x900 and no HDMI.
Story:
I have an old monitor as described above that i want to use for a small project. This project involves an android device. I chose to go with the MK808B Plus. Knowing the connections available on the monitor, i also bought a Mini HDMI to DVI-D adapter cable. I hooked it all up and the monitor detected the input but wouldn't display an image. Just random lines sometimes and then black like it was attempting to connect.
I then hooked it up to another monitor via HDMI and it worked just fine. I then plugged it into the same monitor's DVI port using the adapter and the monitor seemed to see it, and try to display it, but to no avail.
I would like any and all help i can get with this problem. If need be i can even swap the android stick for another model as i have just purchased it.
Thanks
Hello.
I have NVIDIA SHIELD K1 tablet and Sony KD-55S8505C TV (with Android TV on-board). I wanted to play some games within streaming feature. It works fine, but the problem is when I want to use HDMI to display the image on my TV. Once I connect the HDMI-miniHDMI cable, nothing happens... I tried to manually change the display mode to console, but I'm getting a message that HDMI is not connected.
After this I tried the HDMI with other TV and it works correctly. But my Sony is a new one, all HDMIs work fine (I tried them with Blu-ray player and my laptop).
I also tried restarting my tablet and TV many times (I found out it helps sometimes for ppl).
Is there any other thing I can check? No idea what to do.

Did you ever solve the problem? Mirror mode worked on one of my TVs but not another TV.
Yes. There was a problem with my TV's HDMI ports. Something on motherrboard was broken. I sent it to Sony service and they repaired everything. It has worked like a charm since the first use.

Console mode works but not mirror mode so HDMI port is fine.
To me it is happening that my nvidia shield tablet does not recognize when I connect the HDMI. I did a hard reset and everything works perfect again, but after a few days, unchanged nothing stops working again. I did the test with different cables, different adapters HDMI-MiniHDMI and with different screens but I always have the same result unless I make a factory reset again.
Maybe some app, update interferes with HDMI..
Deactivate auto updates in Play store and for Nvidia.
