I bought a mini-HDMI to HDMI converter (just the plug) to connect my cheap no-brand tablet (based on Rockchip 2928) to my TV.
It works for about a minute after booting, but then the image disappears and the TV shows "no signal". The tablet's screen stays off, until I disconnect the HDMI cable, then the tablet's screen comes back on. When I plug the HDMI back in, the tablet's screen goes black, but I get no image on the TV.
The only way to get it to work again is to power down the tablet and power it back up, then it works again for a minute.
I tried three different HDMI cables and two TV's. The tablet is fully charged and plugged in. I tried it with WiFi turned off, but that did not work either.
Any ideas?
Thanks in advance!

Today I tried plugging in my TF101 to a HDMI TV.
I have a mini HDMI to HDMI adapter.
I also have a HDMI cable, and a HDMI to VGA cable.
I tried both the HDMI and VGA. Plugging these into the TV got nothing.
The TV was in Chinese, but I think everything was done correctly. I pressed the change input button Flipped through all possible inputs and nothing.
I hooked another laptop up to the TV via VGA, and it worked fine.
Is there something I need to do on the TF101 to use the HDMI output, or do I need to start testing my equipment?
I really don't want to have to go back to the Asus repair center. I've been in both of the local Asus repair centers so many times for the TF101, that everyone knows me by name and I get ushered to the front of the line. I mean, I'm glad Asus has two full fledged repair centers in Xi'an, but they don't have any parts in stock, so it is worthless to go there.
perhaps the video is hdcp protected, and your TV is not?
The video should appear immediately with no input from user (besides connecting the cable).
I have had monitors and an old TV not supporting hdcp and it just gave me a black image (or no image, same thing).
I have to have my projector off when I connect the hdmi cable THEN turn my projector on.
This is my case and works every time
Hi all, i've got two newbie questions.
First: if I set WSPolicy to "When screen turn off" it means that my TF will disconnect when I close the screen, whatever is it doing in that moment?
I mean, if i'm downloading a file, will the download be interrupted OR the wifi sleep policy works only when there isn't data trasmission going?
Second: I've got my TF101 without the dock. If i buy a female-female USB adaptor and use it with the USB cable that I usually use to connect the TF to my laptop, could I use USB host? Like read an USB pen, or playing with a joypad?
Thank you all in advance.

for your 2nd Q, the tf uses a USB 3 cable, and AFAIK there isnt female to female USB 3. they are selling a USB adapter that plugs into the charging socket. http://liliputing.com/2011/08/asus-eee-pad-transformer-usb-adapter-other-accessories-coming-soon.html .
for you first one my tf has continued downloading even when screen is off. i've set to never when plugged in, but i've notice that when there is no activity it turns off the wifi, cause when i turn on my screen it take a sec or 2 for the wifi to turn blue.
I have a very strange issue.
I have rooted + bootstrap/cwm, 5.5.1-edem-28.
Issue is, when ever I plug only the hdmi or hdmi+charger in, the screen basiccally refuses to work with touch.
But if I plug hdmi+usb (to laptop etc), touch works perfectly fine.
Does anyone have any idea what could be causing this?
Rom is basically stock except removing some Telecom apps and moto-chinese/english keyboard.
I may reflash system to see if any of the keyboard apps were required... But still strange....
Well.... I flashed and wiped completely back to stock. (grrrrr)...
No change, still only have touch response with hdmi only if usb laptop plugged in.
Not, even, with, ps3 usb plugged in...
Αs the title says, the device does not start, it is completely dead.
I tried to disconnect the battery and reconnect it without any changes.
I tried to charge it with an external source without a result.
Any ideas ??? BIOS chip needs reprogramming???
THANKS
Hi there. I have this model. Have you ever tried to turn on with a HDMI output plugged in? In my case it works. But the bios I'm still looking for
Hello! Recently got the tab. C2D8. Couldn't turn it on, the screen remained black. Thought the tab is dead, but it wasn't. plugged into dc outlet, usb tester showed charge. Then installed the drivers and when connected to pc it appeared in device manager. Put it into dnx mode, flashed firmware. Didn't help. Lastly connected it with hdmi to TV, and there came the picture. The tab screen is very dull, brightness wa set to max, though. Is there a software solution, or is it a hardware defect and should be sent back?
Hi. Same happens to me with Teclast X98 Plus II C2D4.
I need to plug my TV through HDMI. Boots in black screen on the tablet but it's ok on TV.
Android runs with very low brightness on tablet screen but Win10 runs ok. Screen looks perfect on the tablet.
So any possible solution?
Thanks.
Hi, did you find a solution to this issue?
I still have the same problem.
Thanks.
The screen on my Motorola Droid Ultra broke (no visual, no touch that I can figure). It has a numeric lock screen (I know the code still) and although I have a computer that has connected to it previously, without unlocking it it will not show up in My Computer.
My primary goal is to be able to pull out Color Note memos and browser tabs/bookmarks for two or three browsers. Having it working would be neat but not required.
I envision this being done by fixing the phone (new screen) or some program that can have my computer serve as screen and input for the hardware.
USB debugging is off - probably because it broke Pokemon Go. SIM removed and disabled (been working on this off-and-on for over a year, at this point I am just stubborn and wanting to learn).
I tried replacing the screen, or rather, pulling out of board and putting it into a different Droid Ultra (same phone, different screen/digitizer and case). It did not work. I opened it up and tried reconnecting, still nothing. When plugged in as one does to charge it intermittently vibrates, which according to the internet seems to mean there is no screen connected. There is.
I have a pigtail USB, microUSB male, micro usb female, and with all that plugged in to the phone, computer (via charger/phone cord), and a keyboard the keyboard does not light up (capslock, num lock) but the phone starts the occasional buzzing for (what I assume is) the screen "unplugged". Not entirely sure how to know is phone is on or off, or if it will turn on at all with the screen "not connected" as it seems to think.
I so want to just be able to pull out the keyboard and plug it in like I can do with real computers. >.<
Any Ideas?
use a OTG cable and connect a mouse, it works!
look for screen mirroring software, to share data with your pc.
