Hey guys,
I have been researching this for a week at least, and eventually decided I wanted to be able to output video from my Note II to my HDMI products and my VGA projector. Now I have run into a somewhat small problem.
The MHL -> HDMI Cable Matters Gold Plated Premium MHL to HDMI Cable for Samsung Galaxy SIII & Galaxy Note 2 in Black - 6ft works perfectly alone
and the HDMI -> VGA Cable Matters Gold Plated Premium HDMI to VGA M/F Active Adapter in Black - also works perfectly alone
But when I connect them together using Female HDMI coupler it only outputs 640x480 60hz . I tested it with my projector and my ASUS monitor. I even tested just the coupler and worked fine.
Anyone have suggestions? I am running CleanAce 4.6 Rom rooted.
Summary: from Note II output from MHL to HDMI to VGA only outputs 640x480 60hz resolution
(on a side note i just ordered a micro hdmi to hdmi cable for my old droid x to see how that fares with the hdmi-vga adapter.)
standard VGA resolutions are 4:3 i.e. 640x480, 800x600, 1024x768, etc. The video card in your Note II is sending on 720p which is 1280x720, which is not a standard VGA resolution, so it downscales to lowest supported *standard* resolution because HDMI does not support analog at all. This is typical behavior with a passive adapter. With that said, 720p over VGA *is* possible, but I think I would try a different approach, such as a Monoprice MHL-to-VGA adapter.
Also, using premium cables i.e. "Gold" for digital signals such as HDMI have absolutely no benefit. These types of cables became popular in the analog days by audiophiles, and they do help to prevent the degradation of analog signals, but not by a huge factor. Of course these companies that sell "Gold" HDMI cables know they are selling snake oil, but consumer don't seem to notice.

Thanks for the info, in my opinion I think combining the adapters is blocking some function that checks back for resolution info. Anyway I totally agree with you on the cable premium stuff, I wanted to slap my parents when I learned their home theater system was put together with monster cables T_T. I just got the cords that were prime eligible and decently priced. Went for same brands hoping they might be more compatible.

I have recently purchased an "OEM" Samsung MHL adapter. it functions as described and gives decent video quality and good audio however what they don`t tell you is that it will only output at 24hz! this means no matter how powerful your phone is it will always be limited to 24fps. this makes videos jittery especially sports and games lag like @#$%. This adapter is FAKE even if it has samsung on it. you can tell because the fake cable has the input cable in the middle. What you want to be buying is the legit Samsung adapter that outputs crystal clear 1080p video at 60hz (60fps) with great audio. it has the input cable offset to one side. Just a warining before people buy the wrong item.
good to know
Where did you buy it from?
Nice share, mate..
Did you used this for your 3vo?
I wanna know why don't you buy the adapter that provide by HTC? Few weeks ago I have a little chat with Htc customer service, and she said that htc are not recommend to use any attachments or accessories that they don't provide or provided by an unknown third party.. At the first time I was thought it was only their bloody marketing strategy.. But, later when I wanna buy a power bank for my 3vo my friend told me that he got a trouble when use it and it brick his blackberry battery like a hell.. So I think it make sense why did they suggested me to use an accessory which they provide and developed.. But a rough case is an exception, eh?

I don't think the adapter has anything to do with the framerate of the video. The adapter is literally just an adapter, taking the video signal from the 5 pin usb and outputting it to the hdmi port.
yes i did test it on my evo 3d on both stock rom and leedroid. actually the adapter itself can affect the quality because i have seen adapters that only output to 720p.
Who has a good one and where did you get it?
GO into a bit more detail on the differences between the good and the bad.
I got mine from an ATT store, or was it a T-Mo store..
Got mine from T-mo..and it works great.

in my case the bad adapter outputs to 1080p (more like 1080i) but the quality is a bit fuzzy with alot of jagged edges whilst the oem adapter produces actual 1080p full resolution and does not lag due to it supporting the full 60hz that the phone is capable of outputting. audio quality is about the same for each. it is not the hdmi cable i am using because i have used several including one that supports 3d @ 120hz.
How are you reading the 60 fps? I have 3 adapters, a monoprice and 2 no-name brand adapters - and all 3 report output of "1080/30P" on my LG TV.

Please post about the actual FPS - and how you're reading the 60fps. I'm concerned that you might be spreading misinformation. After reading this thread, I decided to buy an official Samsung MHL adapter - even though I now have 3 no-name adapters.
On my LG HDTV - all outputs report as 1080P/30FPS, at least coming out of the Evo 3D. I'll continue doing testing on all 4 adapters - so I can post a comparison thread in the accessories subforum. But for now - I see no reason that I'd want to spend $25 for the Samsung MHL adapter I just received, as opposed to the $6 EBAY special I already have.
Hi, i got the official S3 hdmi adapter and i only get 1080I, how can i get 1080P
I have a 1080P 55" sony 240hz led.
Or this adapter only outputs at 1080I?

maybe it outputs 1080p (progressive) at 30 hz only
But my tv supports 30hz, how would i make it choose 1080p and not 1080i?
and the hz are selected automatically depending on the source.
I tried my dell 24" 1080P monitor, it displayed too at 1080I, not 1080P.
Help, i want 1080P
Afaik it's not capable of such a high-bandwith format, and "only" supports up to 1080i.
So no can do as a forum search should've shown.
some people have said it works at 1080p for them in other forums.
Anyone?
Well i think it has to do with how the phone communicates with the tv.
I am only able to get 720p output. I have a 2007 westinghouse 47inch 1080p capable tv. For comparison i have a samsung droid charge that has direct hdmi2hdmi ability, and on same tv i get 1080i output, i am using oem samsung hdmi mhl adapter.

I have the official MHL cable and it outputs at 1080p at 30hz, however i don't want this display type, ok yea great if i want to watch movies, but i want to play tekken with 2 pads, all i need is the mhl to do it's thing.
60fps would be amazing, however i don't believe that it's possible.
Being bottle necked at 30hz on 1080 i / p or even 720 p is just not acceptable, infact it's a kick in the teeth for the £27 i paid for the thing.
Movie's are great, games not so good, although the jelly bean update i just got did help somehow.
By the way i'm using a 47 inch 1080p capable 3D TV
You get full-hd (1080) resolution, but only at half the frequency of 1080p.
However you should keep in mind that
a) this is a phone
b) your eye is only capable of distinguishing ~24 images per second.
infact it's a kick in the teeth for the £27 i paid for the thing.

Please tell me more about how the fact that your phone is capable of playing content at Full-HD on external screens is a "kick in the teeth"

Because it is !!!
Other phones, ie: the iphone is capable of running games at their full potential speed using their AV link cable, which is just wonderful when i hear it from my friends who have iphones / ipads.
Movies is one thing, but to have the ability to have two pads linked to my phone via bluetooth, the ability to play an age old game on a psx emulator on my phone, I then go out and buy an MHL cable thinking that I can play it at the speed the phone is delivering and then it falls on it's arse and runs at a pitiful frame rate due to it running at 30hz and not mirroring fully, that in my opinion and many others is a kick in the teeth, it should have been thoroughly tested by samsung and not just thrown out there, and for it not to be properly looked at, the £27 price tag i paid for it, is overpriced and not worth the money.
Also about your thoughts on the human eye only having the ability to see 24 frames per second, that has nothing to do with it.
The human eye for all it's faults is still capable of seeing a difference between 24 - 30 or even 60+ fps so having a framedrop is not just noticable it's annoying.
Also the galaxy s 3 is not just a phone, it is a smart phone it is also worth £500 and capable of much more than just making and receiving phone calls, so no not just a phone, it's a device capable of much more.
When a device like the S3 has a peripheral like the MHL cable, promising mirroring of the device onto a HD TV, you tend to believe it, well i paid for it and i wished i hadn't because although it does what it says on the tin to an extent, however it does it with latency issues and input delay, rendering gaming obsolete, which is the main reason i bought this thing.
No 1080p and even no 1080i
Guys
Believe it or not the adapters that we buy from ebay or other outlets are not original although they seem to be. They have a galaxy s3 sticker on the box and Samsung usually does not produce a premium product with a sticker on the box to show it is for galaxy s3.
Anyway, even if they are original they are not able to output 1080p. TV reports 1080i but if you watch full hd (1920*1080) videos with them and you focus on the screen you can easily see that the video is played at 720p not even close to 1080p or i.
Samsung has announced that you can watch full hd videos and 1080p output. but these adapters are not able to provide such performance.
Apparently, the original packaging from samsung should look like this:

Interesting. Mine looks like the one in the video below and has a sticker on the box. I have only used it once and was happy with the result. Could it not be that Samsung hadn't produced the boxes for the earlier released product as my actual lead looks the same.

The actual product looks similar but they must be copies since you can buy them for $20-$25 while the original product from Samsung is about $38. The original products have Samsung hologram on the box. However, have you investigated if the output of your cable is 1080p or not?

I have a hologram on mine, bought from a samsung retailer.
But either way i've seen different results yielded from the cable. On my Viera it's 1080i @ 60hz and on my LG it's 1080p @ 30hz, on some HDMI cables it doesn't work at all.
So yea it's a weird one.
Good for movies, utter useless for gaming. Unless it's a slow game, slight input lag.

Should you link up a Live view screen watch or even just about any level -panel Television for computer, Online video Graphics Selection as well as VGA along with Hi-d Multimedia systems Interface as well as HDMI tend to be a couple of quite popular solutions. In theory, HDMI is certainly top-quality nevertheless, in practice this isn't always always the case. Currently, you will find HDMI to VGA Converter cords that are handy If you need to turn be sure you structure a great analog one particular. Hi-def products including HDTVs works extremely well with your cabling.
HDMI is actually searching for structure and so there is no steps involved in conversion between a ripped -panel screen oral appliance any mass media gadget. Moreover, to deliver High-definition online video media, it'll have cabling transferring uncompressed, various stations multichannel audio movie.
VGA on the flip side is actually analog arrangement meaning that the entire process of transformation can produce a modest amount of cut in your sharpness associated with image plus the precision regarding colour. Nevertheless this kind of cable tv does not send sound recording. In order for you sound recording, you will require distinct connections. That's where a HDMI to VGA Converter is actually been shown to be extremely important.
Almost all flat panel tvs such as HDTVs won抰 accept VGA indicate that may be above 1366x768 pixels. It is actually adequate intended for 720p Hd that's 1200x720 pixels, even though certainly not 1080p High and that is 1920x1080pixels.
However , Liquid crystal display computer system video display units can accept VGA alerts from 1080p promises. W?symbolizes sophisicated which means the picture is updated all at one time for just a a lot more liquid display movement. HDMI suffers from Electronic digital high cliff recent all over 40 paws from which this sign can certainly greatly weaken. VGA can go up to a few periods because far prior to getting picture wreckage problems nevertheless you will get footing systems for these several codecs.
Search even more coming from manufacturing in china.
There are plenty of brands regarding HDMI to VGA Converter available now available. A lot of people think that acquiring this type of converter for their devices does not seem sensible by any means simply because they're slightly costly. Even so, a lot of stores along with manufacturers are offering him or her for reasonably priced rates. As a matter of reality, possibly pricey companies can sell him or her for inexpensive price points to conquer the actual improving rivalry amid this device. Regardless of whether buying it on the web as well as offline, You should obtain only through well-known brands.
HDMI together with VGA could possibly have their particular variations mainly because shifting signs. HDMI will be mainly useful for television sets and various audiovisual gear when VGA is required mainly with regard to personal computers. Although a converter can connect the space between the a couple due to the fact at this point, you can watch movies together with sounds from a computer. HDMI to VGA Converter is quite beneficial to companies exactly who need to make presentations from them desktops also to individuals who wants to reap the benefits of their own entertainment systems.
I'm sorry, what's the question?

Here is a picture of the HTC MHL Adapter -- model AC M500. You use it to mirror video and audio from your Jetstream -- or certain other ExtMicro devices. I don't have a television where I am, so I haven't even used it yet.
It was a pretty good investment at $15 dollars with shipping. It is made of plastic, but it is quite solid.
On the left is a ExtMicro connector that states it needs 1.67 A -- this is the rating of the default Jetstream charger. In the middle is a type A HMDI connector. I don't know what the connector on the right is, but my guess is line or headphone out.
If anyone knows the video resolution (I'm assuming 720p) and audio format (I'm assuming stereo PCM) output then please post it.
Has anyone got experience of this? I have a cheap one which is working well. However the output is only 640*480. It says 1080p, but I'm assuming that's the 'input' resolution. What I'd really like it's an output of 1280*760 or better.
Has anyone got a slimport to VGA that's running better than 640*480?

Wow, I haven't seen or used VGA over a decade, but to my knowledge it is limited to a hard 640x480 pixels and 256 colors. I believe you'll only find it used on old security camera systems. If you are down-converting a digital 1920x1080 resolution to VGA, prepare yourself for a 4:3 horrific image.
Is the connector using a 15-pin D-Sub? If so, it may be possible to use a higher resolution than the VGA standard. Link me to the cable you bought and I'll try to help you out further.

By saying VGA I guess OP meant D-Sub (at least that's what we often call it in Poland) and it should easily work with FHD resolution.
Back to the topic - no idea
Yes, VGA is working with FullHD and 32bit colors.

Ah, then the question makes more sense. My fault.
The VGA Connector (aka DE-15) is able to handle up to a 2048x1536 resolution. The G3 should default to 1920x1080 depending on the cable. Wanna link us to the cable you bought, OP?
Yes that's right I meant the 15 pin connector, not VGA resolution.
Here is what I bought http://pages.ebay.com/link/?nav=item.view&id=231790943312&alt=web
I cannot see another one anywhere that looks like (in description) that it would be any different.
My monitor information tells me the resolution that it's running at.
Thanks for thoughts so far

Okay, I assume that either no one uses VGA connector or it only runs at VGA resolution. Shame.
