[Q] HDMI issues

I have an Acer iconia a500, a rca television, and a micro hdmi cable. After many failures i took my iconia to bestbuy, where they successfully connected my tablet to a lg tv with full mirroring. My tv's hdmi input is working properly, (tested by a xbox connected with an hdmi cable). After conencting the cable from my iconia to the rca tv the message unusable signal remains on the screen. Whats the problem?
Thanks for your help!​

I'm gonna take a wild guess here and say that the RCA unit didn't support the a500 native resolution. I wonder if there is a build.prop resolution hack for this.
Are you rommed and rooted?

Did the bestbuy guys used your cable? Try different cable or your original cable to another tv.

Best buy used my cable

Strange in my case worked fine and the next time won't and any other time, I ordered new adapter as well new cable today. I'm reading that connecting and disconnecting need the tab be power off as well tv too.

I tried to have both the iconia and the tv off, connect the cord to both ends, and turn both on . is that what was supposed to work?

Yes that's what is suggested from vendors.

rca and nvidia
This is going to sound stupid.but I had a 42 inch RCA LCD TV.when i would try to connect my nvidia graphics laptop to the TV same issue.even tried a desktop.using the VGA port.would not work.I added a old sis.video adaptor to the computer.it connected right away.there was a web site I found back then about this.
I still do not understand why it was such a issue.but you are having the same as I had forget about it.I did send a report to nvidia and RCA.but no response.
My tab connects to both my TVs now I gave the RCA to my mother and got a Sanyo.its a OK 47 inch.my other is a 40 inch Samsung led and it Rocks can connect anything play videos on the tab to TV across wifi.as well as HDMI my tab will also use a Samsung wifi remote app to control the TV.
Sorry for your luck if you figure it out I would love to know what I was doing wrong.
Thanks good luck erica

Need Seperate Adaptor
It would have been nice if they had built either an HDMI or MiniHDMI port right on the tab, but instead, you need to purchase an adaptor for HDMI output.
Samsung makes one called the "Samsung Galaxy Tab HDTV Adaptor", Samsung part number EPL-3PHPBE. With it, you plug in one end to the 30 pin connector port on your tab, then connect the 30 pin power cable that came with the tab into the adaptor (thus allows the unit to charge / stay charged while in use), and connect a standard HDMI cable to the other end of the HDTV adaptor.
You can purchase direct from Samsung, $49 I think, but I got mine on Amazon for $24.95.
Hope that helps mate.

Does this work now because of 2.3?

Micro Usb to hdmi cable?

Does anyone know if I can plug a cable into usb port on my phone that goes to hdmi on a tv and if it will work to play netflix with audio and video?

No. You can only dlna through wifi.

Dang, I had some high hopes. Thanx for the answer!

To use USB to HDMI, you have to have a special cable, and the phone has to be HW-compliant. The protocol standard is called MHL.
Not our case.
The other option is to have a converter with SW packing on the phone and HW unpacking on the adapter. None available for phones, AFAIK, and these packers consume quite some processing power.

There are apps to use phone as wireless keyboard if you plug pc to tv if that helps

HDMI Query

I know we have hdmi out cables to display phone on a tv but...
Is it possible to do the opposite... use the phone as the display via hdmi.
E.g. laptop hdmi out -> adapter -> phone.

DIYS desktop dock. Some questions.

Hey folks.
I've been thinking about this for a while and I wonder if it is technically possible.
Basically I want to build my own desk dock. It should have HDMI output, charging and USB otg for connecting peripherals.
I'm not sure if it's possible this way, though.
I was thinking of using an otg y cable (with female usb and female microusb) as a base. The regular female USB would be hooked to an externally powered USB hub (just for the sake of having more than 1 USB port available). The female micro USB would be connected to a slimport HDMI adapter (to allow using it with a monitor or TV.
If anyone knows about the technical possibilities please let me know. Maybe someone has tried something like this before?
Thanks in advance

If I'm not wrong - n4 can't do usb otg and slim port hdmi at the same time.

What a pity!
