micro HDMI to DVI

Hello,
I'd like to connect my EVO to my desktop LCD monitor to watch video on bigger screen. Has anyone tried it yet? Anyone know of a micro HDMI (type D) to DVI cable or an adapter? thanks.

you might be able to make your own... just get an DVI to HDMI cable and splice on a type D end to it, not sure if it will go backwards though...

thanks, but I am interested in making sure I am going about the right way. I want make sure all the HDMI 1.4 features are supported in this solution and its fully compatible. Has anyone tried it yet?

Not really sure what HDMI 1.4 features you expect to get when your end connector is a DVI port. If you cant find a cable that goes from the Evo to DVI then you should be able to just go to HDMI then use an adapter to go to DVI. I used have my computer hooked up to my Home Theater via a DVI <> HDMI cable. Worked great, Full HD and all.

thanks. I read there a bunch of new features in hdmi 1.4 and wanted to make sure I go with an optimal option. Seems like an hdmi cable and a DVI adapter is the way to go. This way I can connect to hdtv and lcd monitor.

Yes, its true that HDMI 1.4 is great and has a lot of new things, including 3D support. But keep in mind, this is a phone. It doesn't even output 1080p video, so you'll be fine with the adapter.

Yeah, it can only to 720p output to a monitor/TV.
Something else to consider, HDMI integrates video and audio over 1 connection. If you use a DVI converter, you will lose the audio. I don't know if the EVO will allow you to output the audio out via the headphone jack at the same time or not, but I very much doubt it. So in other words, by converting the signal, you're going to lose all the audio and kinda makes it useless.

hmm.. well that sucks. any ideas on how to get around this problem?

Sure, you can get an HDMI to DVI With Audio converter..but then again, you might as well buy a new monitor with DVI inputs for the price..

Lapdock HDMI

I can confirm that the lapdock does indeed work as a hdmi monitor and usb mouse / keyboard, I had some spare time and tried it out.
*update*
I just spliced a USB A to a micro USB female, works great on my ps3. I just connected USB Rx Tx and ground, Don't bother connecting USB +5vdc red as it sends power up stream and may damage whatever your connecting it to.
here's a video of it in action.

Hi XXXX,
Thank you for your breakout board product suggestion. You bring up a great point about seeing this type of connection more and more. I will forward it on the appropriate people to see if this is something we can make and carry. Thank you again and have a great day!
Take care,
Pamela

Hopefully we see something from this.

great news!

It'd be awesome if you could post some pictures, such as a game console or camera

So far I just connected it to my laptop by holding it. I have an adapter I bought off dealextreme that converts micro female hdmi to full size hdmi. I had to file the female side down a bit but nothing more. If I can find my hdmi genderbender then I'll post it with my xbox360 or ps3. http://www.dealextreme.com/p/hdmi-male-to-micro-hdmi-female-adapter-converter-81206

that is awesome, a female micro hdmi to female hdmi cable is impossible to find I'm sure

What kind of usb slicing is involved?

What are you using the USB for for end-use? USB hub for the ps3?
I'm not familiar with the ps3

The lapdock keyboard and touchpad work just like a normal USB keyboard and mouse. I just used a ps3 as a good proof of concept. But it'll work on anything else that has HDMI / DVI and USB. I'm going to use mine as a cheap rack controller with a KVM.

@callen81, I see there are 2 HDMI to micro HDMI connectors on dealextreme. The one you've posted is $5, and the other one is $4.10. The cheaper one also has a smaller form factor. Maybe it'll fix without any modifications. Anyway, I just wanna ask is there any reason why you've decided to purchase the expensive one? Thanks!
Here is the link to the cheaper one.

Awesome find callen81!
If I get a "Gold Plated HDMI Female to HDMI Female Adapter/Converter" (search on dealextreme) coupled with the HDMI Male to Micro HDMI Female Adapter, I should be good to go right?
@callen81: Out of curiosity do you happen to have Rock Band 2 with a Rock Band 2 Guitar? If so, I'd love for you to run the auto-calibration test on the Laptop monitor and let us know what the Video Response Time is (aka input lag). If it's under 16.6ms, then it is considered sub 1 frame lag. If you don't have this, I'll do this test myself when I get my Laptop monitor up and running and report back!

I don't have Rock Band, that HDMI micro female to HDMI male looks identical to the one I have. Looks just to be cheaper? As well I just used a hdmi female to female gender bender for a wall plate and it seems to have worked fine. A HDMI extension cable would probably be ideal.

Where did you get the female micro usb as well? FRom video it looks like the hdmi adapter takes up almost all the room so I am just wondering how hard is it to fit them plugged in at same time

Is there anyway to make an extender (female to male) for both the HDMI and USB connections? I would love to be able to use my atrix as a webcam for skype or goggle talk since the screen blocks the view of the phone when the lapdock screen is up.

I had to file both the hdmi and micro usb female plugs down a bit, far as an extension cable for the atrix itself it wouldn't work as more then usb data is sent though the usb plug.

Mac Mini?
All the more reason to pick up the dock while its being sold for $50 on ATT.
Someone should connect this to a Mac Mini and you would have your very own PAAH (Portable as Hell Hackintosh)

You should look at the pandaboards, full opmap4 dev board with hdmi.

I plan on doing the same thing.
Ordered two of the link below thanks to your testing.

MHL cable for a normal tv (not a HD one)

I have a normal tv with video in/out ports. Is it possible to connect SGS2 to a normal tv (not a HD one) using the MHL cable? I have seen a video on YouTube where someone has connected the Galaxy S with a cable in 3.5 mm audio port of the mobile to a tv set for a video output. Will this be possible with SG2?
Sent from my GT-I9100 using Tapatalk

AS far as i know this is not Possibile in Galaxy S2.
U can connect ur HD TV with HDMI Cable, but not standard TV with 3.5mm Jack.
i Dont know why SAMSUNG hasnt given this feature on GS2, it would be great if that feature was there.

Thanks for your reply. Can I connect to a non HD tv (normal tv) using HDMI/MHL cable?
Sent from my GT-I9100 using Tapatalk

i suppose yes.
U can connect to any TV that has a support for HDMI. {not sure though}

I don't think non HD tv's have support for HDMI. Only HD tv's have I suppose.

Really exist?...O_O thanks 4 info....i'm gonna search this...

MHL outputs a digital signal.
Standard TVs that do not have HDMI, with RCA jacks, take in an analog signal.
Something needs to convert the signal, so you need a Digital to Analog Converter, or DAC.

Probably because it would take more hardware to do so. Which increases production costs, and would have made the phone larger. There is a ton of stuff crammed into the phone as it is. It is basically a pocket sized computer.
If you can afford this phone, how can you not afford a TV that has an HDMI input?

I connected the MHL cable to a VISIO 720p television and it didn't work, I suppose that MHL sends 1080i/p signals only and your television must, at least, be able to handle this resolution and rescale it.

Not true. Any tv with an HDMI input will work. Doesn't have to be 1080i/p. Did you plug in a power source?

Huh. That's very weird. There shouldn't be an issue with plugging it into a 720p. In fact, I don't think the video output will even be 720p, let alone 1080i/p, unless the output is a video that is that resolution.

I think either the GS2 or the MHL adapter will upscale the image to 1080 regardless the resolution supported by the TV. But it's in fact weird because HD ready should support at least 1080i.

I have seen mini-USB to composite output cable (audio -left and right seperated- and S-Video output cables) for SGS2 on a shopping site but couldn't remember which one now. So it must be possible.

That could be. I can't test, as it works on I everything own... I don't own a TV or monitor that is less than 1080p.

I have my doubts about this - at least, the part that it was for an SGS2. MHL is a digital signal. S-Video is analog. So either the cable was REALLY expensive, or maybe they were trying to pass off a micro-USB to S-Video cable that it (falsely) works for the SGS2? Or it was actually for an SGS1?

The green screen on MHL/HDMI output happens, because of non HDCP compliant TV. All content that we get out of the USB to HDMI adapter is copy protected (HDCP).
I noticed this while I wanted to connect it to as HDMI to SDI converter. Also no capture card will accept this signal. Only HDCP TV and monitor will work.
I'm trying to figure out now how I can get 1080p desktop and gallery output.

MHL on normal TV
I read HDMI on "normal" TV (not HD) works if you use VGA adaptator.
A person on the forum i saw, gives a links to buy one and it was 40$ (For MHL adaptator + VGA adaptor that you need to input in the MHL)

Link? (I'm just curious)
My point above, is that the standard MHL adapter is only like $15. So it would be an additional cost to get ANOTHER adapter to plug that into a TV without an HDMI input. So $40 for that whole get-up would be more expensive. Less expensive than I thought it would be, but still more.
And based on what erzyk says in post 17, there is no guarantee this would work due to standard TVs not being HDCP compliant. But I'm just speculating.
Someone could buy this $40 mystery cable and test it out, I guess. It's just not gonna be me.

I'm agree with you it's very expensive (and i'm not going to buy this thing for 48$)
Here the link:

May be you can found it less expensive (i didn't search, i just saw a person that give the link with this expensive price).

Connecting to a projector

Is it possible to connect the S2 to a stanadrd VGA projector for doing presentations?

You can connect it via the MHL HDMI adapter. From that adapter you must then connect it to a VGA converter... that unfortunately will cost you a fortune ... Also you must bare in mind that you will loose some quality due to the multiple conversions

That's probably using the composite video output.
You can only use

Looking for a MHL Cable for Z3C...

I'm looking for an MHL cable which allows:
Full HD hdmi output
Charge the phone while in use
Can still use USB OTG to connect a keyboard/mouse dongle
Is this even possible?

Works fine for me.
I don't know about the keyboard part, but that shouldn't be a problem I assume.
This particular one is sold out, but shouldn't be hard to find someone else that sells the same. Only bad part is that the power cable part is short.

Thanks!

If your TV has an MHL port, passive MHL cable and you have an adapter, the extra micro usb on the adapter should be ok for USB OTG.

Sorry, but this a dumb, MHL noob question. Will any old micro-usb MHL adapter work, or do I need one specifically for a Sony phone or something?
Thanks
