[Q] Allshare cast conundrum - Galaxy Note 10.1 Q&A, Help & Troubleshooting

Long time viewer, first time posting.
I'm a science teacher and I use a galaxy note 10.1 (original) to do my lectures and I project the image on the screen with allshare cast. The problem is, our school has old projectors with no HDMI and only XGA resolution. Up until now, I have been using an HDMI --> DVI cable which displays the image clearly. The problem of course is that there is no sound. I don't need sound most of the time, so I've been getting by without it.
However, after reading a few threads on here I found that people had success using allshare with the Cable Matters active HDMI --> VGA with audio cable on amazon. So I picked up one of those. I connected the cable and sound, made sure to power it with the usb cable, and it shows up with just a black screen. No matter what configuration it is in, it just shows a black screen. When I pull the HDMI cable out of allshare and put it into a laptop (acer chromebook), the image displays on the screen fine. So the VGA cable and adapter both work.
Allshare works on the projector with DVI, but not VGA, whereas a laptop works with both on the same projector. Any help?

Does that HDMI-VGA adapter support HDCP? I'm pretty sure there's been a change to the ASCD to require HDCP support on the "display" end.

I did see that, though I'm still on the old LJ02 firmware and furthermore the others I've heard with hdcp issues received a message saying that the device was not hdcp compatible. In my case I cant even see the allshare cast instruction screen (it's black) but I CAN see the dongle on my device and connect.

[Q] HDMI output

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?

[Q] How to use the HDMI output?

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

[Q] HDMI, sounds nice but what for?

When i got the TF and red that it has a HMDI port.
I thought, sweet! thats cool!
Then i was looking for a cable and started thinking, why the hell would i connect my TF to my tv?
What do you guys use the HMDI port for?
Only thing i could imagin is maybe stream a movie, but i have a Playstation3 and playstation media server that covers that for me.
Games? you have to look at the TF anyway so you know your hitting the right part of the screen.
What wonderful things can we do with this?
doing slides presentation
You can show yourself playing games on the big screen to your friends instead of 10 people crowding up on a 10.1" screen right.
But yeah, slide presentations actually do use HDMI ports. But most people stick to VGA anyway.
I output my recorded movies (camcorder) to the TV for family to view instead of crowding around the tablet.
I connect a sixaxis PlayStation controller to the dock and play N64 games on the tv. (or Cordy etc.)
connect a wireless mouse to the dock and browse the web using the large display of my 24" monitor from the other side of the room.

Your question raises an important point.
I would have loved to use the HDMI port to connect to TV or OHP Projector etc to make presentations - but apparently the Asus HDMI port is not HDCP compliant and so it would not work with many devices that do accept HDMI inputs but expect them to be HDCP compliant.
I have tried connecting my Tablet to my Panasonic LCD TV using the HDMI port and have failed.
I have tried connecting the same to my computer's LCD monitor using HDMI and it seems to work correctly because the computer monitor does not expect HDCP Compliance.
So I raise the question that you raised.
What can this HDMI port be used for? For me so far this port is useless.
Most TVs will have HDCP in at least one HDMI input.
However, sometimes not every HDMI port on the TV will be HDCP compliant
..so you could check your TV user manual and pick your HDMI input accordingly
Note: There is no firmware upgrade that can turn a non-HDCP input into a HDCP compliant input
_______
If i remember correctly - my Sony Bravia KDL-W4000 only has HDCP in HDMI connection 1
I watch movies on my HDTV through it...both recorded and streaming.
It seems useful to me...otherwise I'd be watching the 100th rerun of that 70's show...no thanks.
I use mine for teaching English classes. Hook it up to a projector for flash cards and such. It's much easier to use for teaching than a computer, since you use your fingers and not a mouse.

Assistance connecting to monitor with VGA

I recently purchased a micro-hdmi to VGA adapter in the hopes I could connect my tf700 to my external monitor. The forum won't allow me to link to the adapter I ordered but it was through Amazon. The brand is Cable Maters.
I connected it, but nothing is displaying on the monitor. No F8 on the keyboard. Is there something I need to set on the tablet? Sorry, not very technical.
Well, you need to set your TV to the correct input port. Check your TV user guide. With my Panasonic there's a "Source" button on the remote which allows you to select the source of your signal, don't know what that would be for your TV

can you say the model of your monitor?
(the monitor must support FullHD resolution of 1920×1080 or be able to scale it.
some adapters issue a fullHD image, regardless of the input resolution)
try to connect to another monitor or from another tablet
The first adapter that I bought on the Internet did not work.

[2022] Pixel 2 video output (MHL cable etc.?)

So in the year of Christ 2022, is there still any sort of way to output video on a Pixel 2?
Story goes so that I have one with a completely busted screen, that does not register anything at all, let alone show anything. Glass broken, touch screen broked. I read there's some sort of a solution, but it requires an app to be downloaded which obviously is impossible in this case.
Is there any solution besides getting this piece of junk fixed?
I was able to use USB adapter to HDMI (not DisplayPort over USB-C alt mode, but older DisplayLink technology over USB 2, plus adapter to USB-C, normally used for adding extra monitors to laptops etc), but it required a DisplayLink app, not sure if it downloaded it automatically or not but I typically install apps from Google App Store remotely, on a PC browser (and select my phone as the target). A mouse should also work with Android but you'll need USB hub, or a bluetooth mouse, so yes in theory it will work but not for DRM content like Netflix, and not sure about booting up, perhaps you can blidnly use external keyboard for PIN or password.
Edit: USB docks for laptops, with HDMI and more USB ports, also use the DisplayLink technology and may be worth a shot
