Was trying to find something about the a500, and stumbled across this. ^
In the second to last sect ion it says
Comes with a VGA adapter for monitors. Nice.

Ive never heard this before. Mine was a refurb, so it didn't dome on OEM packaging - plain brown cardboard box w/ a sticker on it from best buy - and it didn't include this adapter.
Does it really exist? If so, does it work, and where can I get one?
Nah, not sure where he came up with that one.
I am not certain. But I don't think that there is a way to go from HDMI to VGA. At least not unless you get some sort of powered adapter. I'm pretty sure that I've seen those at monoprice.com for 50 or 60 bucks.
Looks like he's just calling the HDMI output a "VGA adapter".
HDMI is digital and VGA is analog; there's no way to go from one to the other without an active circuit. Cheapest converter I have seen is around $32.
It's probably a DVI adapter..
HDMI can't be converted to VGA because it's digital, where VGA is analog.. DVI can do both digital and analog, so there are both HDMI and VGA adapters (just not both at the same time).
Some kind of powered adapter that converts it could work though..
Edit: a little slow >_<
Just get a micro HDMI to HDMI cable. VGA is as old as CRT.
Y U no love Micro HDMI! It loves you!

There are hdmi to vga adapters, and unpowered ones at that. The hdmi spec allows you to send a vga signal over hdmi, and the hdmi current is enough to power it. I'm using one for my ati eyefinity now.

Thanks. That's good to know.
What you should know about these converters though is that they produce a small but potentially noticeable lag. That said, I use a self-powered converter every week for presentations and it works just fine.
One more thing: Android by default only outputs a digital signal and Acer didn't hack the drivers to support any of the optional modes HDMI allows... So you get a plain, unencrypted digital 720p signal from the Micro-HDMI port.

I have a micro hdmi to full hdmi that i use for my xoom and evo to connect ot my 65inch tv. It works great and I love it but in my bed room i have a 30 inch tv and it only has dvi input. So i bought a hdmi to dvi adaptor and was so happy to get it and my luck it doesnt work. The tv doesnt detect the input and says its not active. I got the tv to display the xoom a few times but the tv pops up a box saying Signal test...which is what it does when there is no signal/input. I tried to plug it into my monitor with the dvi adaptor and the screen is blank. Really makes me sad i was so exited. I pluged my evo into the cable with the dvi adaptor and it does work so im not sure why the Xoom is having issues. I also plugged in my laptop into the tv with a full hdmi cable and used the dvi adaptor and it worked perfectly. Not sure if anyone else has the same issues. Any help would be appreciated.
Thanks

Does that TV display 1080p? The Xoom will mirror itself in 1080P - If that TV cant handle it, it wont display it. Most old school 30 inchers are 720p max

To be honest, if its working fine with the cable on another TV;
then its either the adapter or the TV input - but the most logical explanation, is that the TV cannot display 1080p.
Currently there is no way to scale down the mirroring - maybe in the future tho!
its strange because I can get the tv to show the xoom sometimes but i get that test box floating around even tho i can see the image. so it works kindof. little zoomed in and no way to disable the test feature. Really sucks because that was one of the main reasons I liked the xoom so much. wanted to play my N64 emulator on my tv from my bed lol. Tv was free so cant complain i guess. Just need to save for a newer one.
Pretty sure the output is 720p. It doesn't upscale.. it chops off the bottom to fit 1280x720.

Ive been trying to do this too and have discovered why its not working. Basically the Xoom does not output the required 5 volts needed to project the signal through the DVI adapter and onto the monitor. The only way around this is to add the 5 volts the best way I can see to do this is to purchase this (or something similar, I'm pretty sure there is a US made equivalent):

Mini DisplayPort to HDMI Converters
+++++++++++++++++++++++++++++++++++
Mini DisplayPort | to DVI (2 DVI Output) Converter
This video converter lets you connect your Mac or other computer with Mini DisplayPort or Thunderbolt data port to a pair of high-resolution DVI displays!
The MMP-MDMP2D01 converter uses the Mini DisplayPort input standard, which can also be used on computers with the newer Thunderbolt data port. The converter then sends the video output to two DVI+I (digital only) displays at resolutions up to 1920x1080p.
By using HDMI circuitry, the converter supports full HDMI High Speed capabilities, including 225 MHz/2.25 Gbps per channel bandwidth (6.75 Gbps total) and 12-bit per channel (36-bit total) deep color modes. The unit comes complete with a 33" Mini DisplayPort M/M cable and a 5 VDC AC adapter (US and Canadian UL listed).
I bought an HDMI cable today so I can put Netflix onto my TV. I have an older HDTV, from 2004. It's a Panasonic model number pt-47x54j. When I plug my tablet into it, the little Android dude pops up onto the TV and and says 720p? I checked the owners manual and it says that the TV is only capable of 1080i, or 480p and 480i. I plugged my tablet into a more modern HDTV and it works just fine. Crystal Clear. Is there any way that I can get my a500 to work on my Panasonic TV? Attached is a screenshot of my TV's owner's manual on the page where it talks about HDMI inputs. Thanks in advance...
From the best of my knowledge you can't change this.Athens beat solution I could offer is Logitech Google TV.it rocks.and 70.00 amazon.
It can't be changed without hacking the drivers -- and even then micro HDMI is only capable of 720p output. All you can do is use a different TV or an adaptor (probably cheapest, but may lower video quality).

Thanks. At this point, I'm just using my tablet to watch the movies on. That's good enough for me. Once my TVs start breaking and/or if I get this dream job that I'm currently chasing after, I'm going to get a more modern TV and all of my HDMI cable worries will go away. I put the Netflix App on my phone too. My 3 year old freaking loves it!! He is always asking for my phone to watch cartoons on. It's hilarious. haha
Of course, I'm still going to try to figure this crap out with my current TV. That's the fun part.

micro HDMI itself is capable of 1080p, but the tablet will only output 1080p if there's a 1080p stream (such as a 1080p movie). Netflix will not do 1080p, though.
Hey, wondering if anyone else is getting varied resolutions when using a micro HDMI -> HDMI cable into a TV. We have a 37" plasma 1080 capable but I only get 480 out of, and our 42" LCD only gets 720.
Both are default numbers as I haven't been able to find anyway to adjust them. Have tried stock video player, MX player and YouTube through all to no avail.
If anyone has any ideas, I'd be most appreciative.
Cheers

You may want to check your hdmi cable. If you have a "standard hdmi cable" , and it supports up to 1080i/720p. The type 2 "high speed data hdmi cable" supports 1080p, 3d and high color. Your tv's and tablet may support it, but you may be using a standard hdmi cable.
Source: http://en.m.wikipedia.org/wiki/Micro-HDMI#section_2
Listed under specifications/cables
I haven't looked, does the n10 support 1080i?... I notice most devices and movies I look at only support "p" areas (480p, 720p and 1080p) relevant since I plan to buy a big screen LED tv with my tax return...
Cheers for the heads up, I've read in other forums that the n10 downscales to 1080, but haven't seen it first hand.
There's a few variables at play, I'll get some specs from the TV's, I haven't seen any different type of cables on eBay else I'd have got the better one (i spent $15 on this one).

I purchased a $10 off of Amazon. Supposedly a HS cable. Real thick and almost 6 feet long.. Nice, but the TV I had planned to use it on, it did not output sound! 2 other sets, and the sou d works fine. I read here that it is a cable/tv combination problem.. Plug in another hdmi and the sound will work fine. Haven't tried it since I hooked it into the stereo via blue tooth.
I am planning to buy a small converter attachment,(pigtail cable or plug) that way I can use the hs hdmi cables I already have on the tv. I am still not convinced that it isn't a problem with android, but we'll see.
Since the Ouya only has Ethernet, AC, USB and HDMI. Will it be possible to connect to a standard TV by RCA connector or by a scart?AV? VGA? Composite?
Hi, so far the Ouya isn't known to produce analog video signals, only digital (via the HDMI out) thus, to use it with a analog tv you would either need a video amplifier (with HDMI in and AV-Out) or a signal convertor.
If you currently don't have one of those then I would suggest buying a HD-TV as the two methods I advised you of would cost at least $100 anyway.
I'm assume you mean composite or component, and RCA stereo audio output. If so, Ouya has only stated HDMI.
As the above said, you would need an digital to analog converter. An amplifier wouldn't help you in this situation. Unfortunately, you'll spend more on the converter than you would the Ouya. Well, maybe you can find an old used FuryHD for $100 to handle video. There are other issues you have to take into account such as will the converter tweak the signal to make sure your TV will accept it is a big one.
I had to go that route when I setup a home theater PC, and my HDTV predated DVI; it only had component HD input, but the HTPC had display port. I got an HDFury2, which just came out, and ran about $250 at the time. That was cheaper than buying a new good quality 55" HDTV.
Hopefully that was helpful.
Thanks for the information guys, look like I will just pick up a cheap Hd TV.

I just connected my SM-N9005 via HDMI to my monitor (Dell ST2420L) and everything is fine, except the resolution. It looks a bit blurry to me.
When I checked in the monitor, it says:
Current: 1280x720 @ 60 Hz
Maximum: 1920x1080 @ 60 Hz
The native resolution is shown 1080 x 1920. But this is not the case with HDMI.
I've tried 3 different apps to change the HDMI resolution (with Root) without success.
Does anybody know how to change the resolution?

What kind of connection do you use? If it's MHL, then it must be due to the version of MHL adapter. AFAIK MHL below 2.0 does not support Full HD, that is 1920x1080 @ 60 Hz.

All HDMI cables are essentially the same. http://news.cnet.com/8301-17938_105-20056502-1/why-all-hdmi-cables-are-the-same/

after some cables getting 1080
I had one MHL and got a 720p output. Switched to another one (mhl2) and am now getting 1080p, according to the monitor. However, many apps still don't take advantage of the real estate. They still pick a display format that assumes the device is a phone and so for example, only show 3 or 4 items in the email list.
Android UI stuff isn't ready yet for the kind of adapting/switching we're used to on Windows/Mac/X.
So you are saying that it's probably because of the MHL cable?
MHL cables are same. MHL hardware is different. The MHL plug has 11 pins.
What brand did you get that works?

I believe there're some apps and/or ROMs that let your phone run apps in tablet mode, for example: http://highonandroid.com/android-ap...-mode-on-any-rooted-android-smartphonetablet/
Though this will be of little help if the app does not have a "tablet mode".
Install xposed installer, there's a tweak that allows you to use the resolution you want to on your TV. I dunno what is called but I'm sure it is in xposed installer!

Thanks! I forgot to check Xposed! Will report in a minute
Edit: Unfortunately I wasn't able to find any mod for HDMI except Fullscreen YouTube
Edit 2: Just used Galaxy S3 with the cable and works just fine on 1080i. So it's definitely not the cable. Sounds like firmware bug (MK2)
Have you tried changing the pixel density (PPI)? PimpMyROM and Xposed can both accomplish this task. Since screen mirroring simply takes whatever is on your device's screen and relays it onto the HDMI output, you can start by taking better advantage of your internal 1080p screen! I recommend 360ppi for this device, as that is the setting I am currently using. You can also go as small as 320ppi without losing sharpness, although text will be extremely small at this setting.
Im not inrerested in changing DPI, just the HDMI resolution
MHL 1 supports up to 720p (1280x720 @ 60Hz) or 1080i (1920x1080 @ 30Hz), MHL 2 also supports 1080p (1920x1080 @ 60Hz).
There is no way to change the resolution, the phone will output the highest mode it detects as being supported.
There are a huge number of fake MHL2 adapters on the market, if you think you got an OEM one for a good price, then it's probably a fake one.
Remember that the native resolution of the Note 3 is 1920x1080, so you can expect a 1080p TV to display the same as the phone does, it doesn't have a special "HDMI mode".
As computer monitors generally don't support 1080i, then the output will fallback to 720p mode and as LCD screens generally don't scale very well, the resulting picture will look fuzzy.
Your only real option is to probably going to be to buy a proper MHL2 adapter. The monitor will probably also not support MHL directly so you'll still need the external USB power supply, while most TVs will accept the HDMI input, they don't support MHL so won't supply power to the adapter over HDMI. It seems to be mostly higher-end models that support power-over-HDMI.

It's not the cable as it's working fine with S3 @ 1080i. And it's special 11 pin for new Samsung models so it's MHL2 compatible and doesn't work with other devices. It's not the monitor. Other people report same problem and nobody knows a fix yet. I'm sure it's the firmware.
In the system files it shows available modes:
1280x720-0 and 1920x1080-2 (I don't know why -2, but nothing can change it, I tried)

Having an 11 pin connector doesn't guarantee that it's an MHL2 device. I have 2 such units sitting in a drawer beside me which have a MHL 1 SIL9292 processor chip in them instead of the SIL9296 required for MHL2 & 1080p support. It works fine with my Note 3 but they do not support 1080p output.
MHL cables are not straight-through MicroUSB to HDMI adapters, they all have active processing circuitry in them. It's not like a regular HDMI cable, that's why the plug on that cable you bought is so huge, if you crack it open there will be a circuit board in there with a MHL to HDMI processing chip on it.
I know 2 other people with Note 3's who have genuine Samsung MHL 2 cables and they both get 1080p output on their TV's.
Computer monitors except for some rare exceptions will NOT support a 1080i input as they don't have deinterlacing circuitry so a lower support resolution will be negotiated. Having the issue on a TV that definitely supports 1080i is a different matter.
The Galaxy S3 is natively a 720p display so scaling will not be required meaning that you will get a much better picture from a Galaxy S3 @ 720p than a Note 3 @ 720p as it can display the image 1:1 without resampling.
ALSO - The Galaxy S3 itself doesn't support MHL2 so is not a good reference.
Read all about it: http://www.galaxymhl.com/
Thanks for the useful info. That explains a lot and I will buy genuine from Samsung. Cheers

You might have to go find an MHL1 adapter instead of an MHL2 adapter.
