I just got a MHL adapter for my phone to plug into my computer monitor at work but am having a bit of an issue. I have an HDMI to DVI cable and when I plug it into my monitor its a few seconds to get a picture and when it does it flashes for about half a second and then goes black and this happens until I change inputs or unplug. I tried it on another monitor in the office and it worked fine. Does anyone have any ideas why the MHL adapter wouldn't work with one monitor but works fine on another?
Maybe someone else can answer this for sure, but perhaps the monitor it works on has HDCP?

I searched the threads on this but can't find specifically what I'm looking for.
I purchased the Z Pad dock for my G Tab and just got it in and hooked it up. It will charge through it and the USB works, haven't tested the RJ-45 connection but I connected it to my TV and it will not display anything. My TV has a DVI connector and I have a HDMI to DVI adapter and I know the adapter works because it works with other devices.
Also, HDMI and DVI video are exactly the same digitally as far as signal go so my question is, has anyone else used an adapter to connect it to the DVI port and if so did it work or not?
Just wondering if it needs to be specifically connected to a HDMI port to receive other feedback from the port to the device to turn it on. My Droid X will connect with this method.
Also, When I got the dock it had a rattle, so I cracked it open and the counter weight was loose as the mounting tabs were busted off. It was banging on the ribbon cable to the dock connector. I disassembled it and examined the cable and saw no damage and since all of the other features work I figured it might be the connection method but want to make sure. I secured the weight and closed it back up.
I also ordered a HDMI to composite RCA converter but haven't received it yet as I want to be able to connect it to any available display so I am not able to try that yet.
In short, has anyone else tried to connect it using a HDMI to DVI connector and not have display output? P.S. I did have the charger connected to power the internal dock board as it is not just a passthrough.
Just want to know before I attempt to send this back as a defect or hunt down other methods of connectivity.
Thanks in advance,
Brian
I have found that the hdmi out wont work unless the power supply is connected! so basically make sure the tablet is charging when you want the HDMI to work! Hope this helps!
Yes, I know that and said I had it plugged in. Thanks. Just wondering if someone else had trouble using a HDMI to DVI connector with the G Tab.

Brian, Not sure how much it helps but I have a Ztab and it is working fine going HDMI --> HDMI on my TV. Are you having problems with a HDMI --> DVI connector? If you haven't already tried it, you could try rebooting the tablet with it in the dock. I've found that helps with mine sometimes.

well Brian I can tell you that Hdmi to dvi Works well.
I have the same dock, and i use it at work all the time via dvi adapter.
I assume your dock still works not using the adapter?
I plugged mine into my TV and it showed right up, but of course, I am using HDMI to HDMI. The only thing I can think of that might be a problem is you'd lose sound in the process, unless its smart enough to know the sound isn't connected via HDMI and keeps it coming out the speakers.
I did try to reboot it and it did not show up. Thanks for posting that it did work with the DVI adapter as that is how I have it set up. I know the adapter works as I use it with my Droid X and it works with that.
I will play around with it some more and wait until the coposite converter I ordered comes in as that is HDMI in to Composite out and see if that works. If not then I will send it back as a defect. I bet the counter wieght being broken loose inside did something to the ribbon cable.
Anyone use a HDMI to composit/RCA hookup yet? Mine is on order and am hoping I can use it on my older 4:3 40 inch Hitachi.

Do you use it to display text? I find the quality from my Zpad, using the dock, to be pretty average for text. Did you change any settings?
Cheers, Mal.
I received my monoprice MHL adapter, plugged the hdmi cable into it, plugged the power into it and plugged it into my phone. the phone shows HDMI hooked up and my monitor will alternate between showing whats on the phone and going to a white fuzzy screen then back to mirrored than fuzzy every couple of seconds.
I plugged my brothers sensation in and it works fine so I doubt it's the adapter, he is rooted running a custom ROM.
I am unlocked and rooted but running stock rom, T-Mobile USA version.
So I went into T-Mobile and asked about this issue, they didn't know, they called tech support who in turn told them to call HTC. They gave me HTCs number, I called and explained what was going on, HTC tells me the phone ISN'T MHL compatible, that we're supposed to use the media link dongle, which costs about $100.
He suggested I try just a straight up micro hdmi cable to my tv instead.
So an older phone (sensation) has the ability, but this new high tech, best of the bunch phone can't do it, what a bunch of ****.
Edit: OK, I figured out the issue, I was running an HDMI to VGA cable to my monitor, since the monitor is a VGA connection. I then went ahead and hooked it up to another monitor that had a straight HDMI connection and it worked perfect, so VGA HDMI cable no good, straight up hdmi to hdmi works great!
Edit 2: So I just tried the MHL adapter again with the vga HDMI cable, and now it works. It's like it needed one cable to make it work and now it will work with the other, nothing changed except that I tried it another TV.
a HDMI to VGA cable? as long as you dont have special equipment this cable can't be used for anything HDMI is a completly digital standard. DVI is digital + analog so a VGA - DVI adapter is possible, but HDMI to analog is without special hardware impossible.

You are correct sir, my bad, it is a DVI cable. So just replace VGA with DVI in my first and second post.
The cable I have is this one.
Thanks.
Okay. Could be a problem with HDCP.

I'n having this issue too.. still unresolved
My MHL came in 2 days back. Hooking the phone up keeps alternating between what's on the phone and the white noise screen. I have a straightup HDMI cable going from the MHL to my LCD TV.
Any suggestions are welcome

OK, I noticed if i just go and hook up my cable to the mhl the problem comes back, the solution is to hook everything up to the phone, then reboot the phone and the problem will be gone. One other thing is make sure you have your media volume turned up as it affects sound output, so if your media volume is muted, it will also be muted or whatever volume the phone is set at. I thought I was nuts when there wasn't any sound coming from my stereo until I realized that I had my volume all the way down.
DO the reboot thing and it should work no problems, also, our phones don't need to be plugged in to your power cord to use the MHL, so I'm wondering if the MHL adapter is even necessary for us if we can live without the power cord needing to be attached.

Thanks.. Will try and circle back..
Re: The power cord, not sure if it's 'needed' but I'm guessing without external power the phone wouldn't last an hour.
Seperate issue - When I last tried, I was playing around with it and the phone heated to a point it was slightly uncomfy holding the phone.

Yup, without the external battery going to the phone it will drain dramatically. I also noticed the heating issue you mentioned.

Update: So I tried hooking up all the cables to my phone, restarted the phone and then plugged it into the TV. It still gives me same results unfortunately. I get a display but it keeps going away every few seconds and the white noise screen appears.
What a buzzkill... My old phone (Sensation) was flawless in this respect
I have been researching this issue for a while, but I have never found someone that posted a resolution, so I figured I would just ask it on my own. I have the galaxy s4 with a MHL adapter to hook up to TV in my car. It's great for streaming Netflix, Hulu, Sunday Ticket, etc. However, the charging on the MHL cannot keep up with the phone, even when I am not using video. I have read some people that believe it is because the phone recognizes the MHL as a USB charger instead of AC (which is what is detects when plugged directly into my car adapter) so limits the input to 500mah. I have not been able to find an app that works on the s4 to measure charge input though, so I cannot determine what exactly it is charging as.
So, has anyone been able to use their phone in MHL while maintaining the battery level so it does not die 30 minutes in? The only thing I can think of is upgrading to a MHL 2.0, which apparently has better charging, so I ordered one of those..I am not too optimistic about it though.
Thanks for all tips and suggestions!
I was hoping someone would have some insight regarding a problem I have using an MHL adapter with a DVI connector attached on.
I have this MHL adapter: http://www.amazon.com/gp/product/B00827EGG2/ref=oh_details_o09_s00_i00?ie=UTF8&psc=1
I'm using dvi adapter: http://www.amazon.com/gp/product/B002JCQVW8/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
And connecting it to this projector: http://www.amazon.com/Optoma-EP739-...TF8&qid=1381161207&sr=8-1&keywords=optoma+739
The projector doesn't have an HDMI cable so I thought i'd throw on an HDMI to DVI adapter to get around that.
I've used the HDMI cable and MHL adapter on other stuff before and they work great. I've used DVI adapter and HDMI cable to connect my laptop to the projector and that works too.
When I use the MHL adapter with the DVI adapter and connect it to the projector, my One S Screen becomes all scrambled and the projector detects a signal but it displays a blue or black screen or occasionally I see about half of the notification bar and the rest of the projection is the blue screen. Also, my phone freezes at that point and I have to force restart it.
My scrambled screen one s screen looks different every time, but something like this: http://img8.imageshack.us/img8/3894/img20110927034536.jpg
If the projector's manual will help, it can be found here: http://www.projectorcentral.com/pdf/projector_manual_2566.pdf
I'm running rooted stock rom.
Any thoughts?
Thanks!
htc media link hd
did you try the htc media link?? i know its a bit expensive but i think that would be your best thing to try
you'll just need to connect the media link to your projector and use wifi to set everything up... no need for mhl and dvi connector
So I recently got a MHL/OTG adapter off of ebay. The HDMI out and usb ports seem to work no problem. My problem is that when connecting my charging cable to the MHL hub my device isn't getting any power. I have no indications of my battery % going up. That means if I were to stream a movie onto my TV it would work fine but I would run out of battery fast. Does this seem like there's something wrong with the MHL adapter? Is my samsung battery charger not strong enough? Any help with this is greatly appreciated. I have done a bit of research on this and found mixed answers.
Actually... That's normal... An otg adapter puts your device into "power output" mode so it can power a flashdrive or other storage device... So the input/charging mode gets turned off.
Plugging your charger into the hub helps power the external devices so they don't kill your battery so quickly...
No. MHL 3 is meant to charge in parallel. Works on mine. It charges at 700mA only though, pretty slow. You can check the current by Synapse App + Skyhigh Kernel. I think you can configure higher charging rates as well(didn't try). MHL 3 is speced for 2A current.
Yeah... MHL works that way... But the OP says it's also an "OTG hub off ebay" .... So were not just talking about a straight MHL adapter... If it's an OTG hub triggering OTG mode on the tablet... Then it won't charge and it's not suppposed to.

Hi, I also have a MHL/OTG adapter like yours (MHL/OTG/Card Reader) MHL-HDMI works flawless but OTG doesn't.
A USB pendrive that works flawless with an OTG cable it doesn't recognized in the hub while MHL>HDMI it's working.
@xmilar can you please post the link to the MHL/OTG adapter you bought and while yours not charge, are MHL+OTG working simultaniusly?
Thanks!
I've looked into MHL adapters for my Tab S 10.5 and LG G3 but it would require multiple cables and if I replace either or both items and the new item uses a different MHL, I would have to spend more money. I ended up just buying a Chromecast that does the same thing and wirelessly. Best $30 I spent
Hello, I ve bought an MHL adapter, the one with usb connector to charge the tablet when using the mhl, anyway nothing is working. The tablet doesnt charge, and shows 2 times the following : HDMI Connected, then after one second HDMI disconnected, two times. On my Sony phone works with no problems. I have skyhigh kernel and stock rom.
Probably it's not MHL 3?
Sorry for the late reply, if is not MHL 3 why is it working on my Sony Z1 compact with 4.4.4 rooted also.
If the adapter works on a Sony device then its probably based on a standard micro USB connector. According to the wikipedia entry for MHL newer samsung devices use a propriety 11 pin micro USB connector for MHL. There is mention of a "tip" to adapt between 11 pin and 5 pin, perhaps you could buy one of these?
