Seeking a workaround to modify the HDMI output on the TF700 - Asus Transformer TF700

I bought the Asus "MicroHDMI to VGA" cable to allow me to hook up my TF700 to projectors and to LCDTV's generically - since I travel a lot and wanted to use this product to deliver presentations to clients.
Unfortunately, it refused to output anything to a number of devices, only reflected highly zoomed cropped versions on others, and worked on a select few - which confirmed that the cable and the HDMI port are both working and not defective.
Upon checking with Asus, they reverted as follows:
unlike a PC, Android on the tablet doesn't allow any resolution adjustments. So it'll be outputting 1920x1200. You didn't mention the make/model of the projector but you should check the available input range and check how this is handled, especially if it's not a full hd projector. Also check the projector settings and see what options are allowed for zoom/scaling the input.
I checked some devices, and it turns out that they are only capable upto SXGA (1280x1024) on the VGA interface. What Asus did not clarify is whether the MicroHD to VGA converter only provides as an output what is the input? I noted that this works with the TF300 and TF200 as well - both of them are at 1280x800 - which means that this cable should be capable of outputting that signal... is there a way to make the cable downconvert to a static output of 1280x800?
I also noticed that the firmware 9.4.2.21 on Asus TF201 came with an HDMI output tweak "New display mode of HDMI output - Scale mode(Default) and Crop mode (Detail comparison in next two sides)" Is there someone who can provide this as a port for the TF700? Perhaps this could solve the issue?

It would be great. I bought it for my presentation. Maybe a custom firmware in the future...

I noticed this annoying issue even when hooking up my tablet straight HDMI to my TV. My TV is a bit old and garbage, and doesn't offer any scaling, so unless I'm watching a video or something and just on the web or desktop, I get an image that is mostly cut off, and largely useless. Odd thing is, when I first hooked it up, it mostly scaled properly. It wasn't until I watched a video that it refused to scale again. I also noticed that when I first hooked it up, I got HDMI settings in the Settings, only offering 3D settings but still a start, but now I don't get anything. Definitely strange, not sure if it's a garbage cable, garbage TV, or something odd in the software.

Personally I am hoping that we can use the HDMI output as a secondary monitor at some point.

the cable can't down-convert. all it can do is carry the signal that is applied to it. unless you find some way of outputting a different resolution on that port, you're stuck with 1920x1200. i don't know of any non-monitor display devices that accept HD resolution input on a VGA port. anything manufactured in the last decade or so will only accept HD input on a digital port (hdmi, dvi, displayport, etc).

I did notice the HDMI output tweak on my TF201 - It let you crop/or scale the output slightly. Basically, it let you see 'Home, Back, Menu' icons on the TV, where usually you don't see those (b/c they are cropped off). If you set the HDMI output to "Scale" you can see them. It was an option though in the settings app. I don't see the same option on the TF700.

I had that menu appear for me once (yes, on TF700T). The weird thing was that I saw it first after I had disconnected HDMI that time...
Try to "force stop" the Settings app with HDMI connected. If that doesn't help, try rebooting with HDMI connected. It should either appear as its own menu in the Settings app or under "ASUS Customized Setting", I don't remember.

I have never seen the crop or scale options on my tf700... not sure how any of you have seen that with a stock ROM. Here is the kick with a 1920x1200 monitor.... it will output 1920x1080! It will not allow you to output the entire desktop unless the monitor scales the image itself. Once it is scaling and you can see the system bar, now go into settings hdmi.. then hit back. You will see the image fill the horizontal resolution properly, but vertical is cropped and cuts off the system bar. In either mode, you will get 1080 on the vertical res.
I WISH it would output the full res with ANY HDMI monitor!! I have several monitors that are at the native res and none of them will allow you to display the screen properly. If anyone has any ideas how to force the hdmi res to the native res of the tablet, please let me know! This would solve an issue that I have been trying to fix or find a workaround to ever since the release of this tab.

When connected to my Samsung TV (1080p), I get a cropped image and slightly overexposed colours, it's the same on at least one other TV. However, If I connect the pad to the HDMI/DVI slot and set it to DVI mode, the colours look much better and the display is scaled instead. This is the same behaviour as my old Notion Ink Adam with Tegra 2 (and any PC I've connected to my TV), so I guess the Tegras are actually outputting a DVI signal. :S

Outputting in 1920x1200 is a no-no if you want to connect it to a TV (which I do).
Ideally, there should be 3 options:
1) Output full desktop as 1920x1200 (for monitor usage)
2) Output full desktop as 1920x1080 (scaled down, for TV usage)
3) Output desktop minus system bar as 1920x1080
This way, you can pick the mode that suits your setup the best...

Agreed. I just want the stupid thing to do native res... but the rest is icing if I get it!

It appears to me that tf is able to change resolution. When i observe hdmi output on my tv and tf is on home page i get full res output. Part of screen is masked out until i resize tv vertically. When i play netflix movie the resolution changes to 1080x720. I think i saw tf locking in setting. When i first saw a video on tf with hdmi i think the video played on tv and tf. After Netflix video, streams like YouTube only shows on tv while hdmi is hooked up. This got me thinking if tf is locking settings maybe you can play a netflix movie and then get 1080 on your projecter. However even after netflix movie hulu + did not work when hdmi hooked, indicating resolution is dependent on app. Lets hope this gets corrected with jelly bean.
Maybe those that have loaded 300 jelly bean can commit on this. From what i read, i think, 300 has the settings, what happens on tf?

Connect infinity to tv via hdmi.
In hdmi settings on infinity check 3D and you will get 1920x1080 picture without bar and full screen picture.
Now you can watch movies and play games on full screen.
bsplayer can play movies only on TV if you have connected to infinity.

It is capable, and does change the resolution that it is using to output based on the application if the app has those settings included. That is why you get a different res on netflix. The issue is that there is no reliable way to control the resolution or the way it displays on TVs and monitors.
It would be great if the hdmi menu actually had some useful settings like the ones mentioned earlier. More important is that we at least get the ability to scale or crop as a built in setting for this tab. I miss it... used to have it on the prime.

the video signal over HDMI and DVI are actually the same. HDMI just has audio channels in the package as well.

Not exactly, dvi actually has an additional 5v signal that is needed to tell the monitor to turn on... our infinity lacks this signal just like the Xoom tablets. You can test this with a microhdmi to HDMI, then add a HDMI to dvi adapter and try to get a dvi monitor to work.

it is possible to change the resolution of your device. look at the link below, i have done this some time ago on my tf101 . dont know if these exact propertys are the same on tegra3 , cant test it on my prime (rma)
needs to be done in terminal and i think it needs root too.

Thanks _ looks like these is no solution after all
Everyone - many thanks for your inputs and contributions...
Unfortunately, it looks like there is no solution out there. The only option I see is to buy an external adapter, which takes in HDMI and gives out various types of outputs - like this one here... http://www.amazon.com/gp/product/B002SFT3ZI/ref=ox_sc_sfl_title_1
Since I don't live in the US, I would not want to buy this at a risk without knowing if this works... if any of you do test it out, please do let me know... will really appreciate it.

huh? the VGA standard has and will accept resolutions up to and above "1080p" I've used 30 year old 3-tube CRT projectors that will display resolutions higher than apple's "retina display" Matter of fact, I am currently shoving 1920x1080 @60hz progressive into a mitsubishi CRT rear projection TV through 5-wire (VGA breakout into RGBHV)
that and HD is definined as ANY resolution above 1280x720, even most ****ty LCD TVs will take 1366x768 at a minimum though an analog input.
you're only right about the cable, it will not change scan frequencies/dot clocks on the fly, that's for the hardware to do.
that or just carry around a small scaler, DVDO makes some nice products that are very flexible with many different outputs and their magic little boxes will let you put ANY signal on ANY display as long as you've got some combination of cables and adapters to make the connection.
scalers are your friends!

[Q] for those of you with an hdmi cable

got my motorola micro hdmi to full hdmi cable in the mail today. plugged 'er in and the picture came up right away. however, the whole screen of my xoom is not showing on my tv. i cant find any settings on the xoom to adjust the tv out.
any suggestions?
You're not going to see the status bar.
i know that, but it also cuts off about an inch on each side, and a small part of the top and bottom. its almost as if its zoomed in a little.
Well that's your TV then. Some do that.
ok, that's what i figured. just wanted to make sure there wasn't a setting on the xoom.
Sent from my Nexus S using XDA Premium App
Play with the different zoom options on your tv. You might have one that fits the entire image on the screen. This problem is caused because the xoom screen is 16:10 aspect ratio and your TV is 16:9
On my TV I have input settings that allow me to change it to the devices native ratio, or zoomed in on that. Maybe yours will have something similar.
I haven't tested my Xoom on the TV yet, but I know when I had my desktop hooked up to my TV, I had to have special settings for it because it would never display correctly.
OK Find out how to turn off over scan on your TV and it should solve the issue. Having over scan off for HDMI connections also improves image quality so its good to have it off

[Q] 720p not scaling properly even with 3.2 update

I have LG plasma TV which only supports 720p resolution. Now the problem is that the image stretches out from all sides when I hook up my transformer via HDMI.
I thought the 3.2 will fix that since this was mentioned in the changelog: "HDMI output resolution quality scales better for greater compatibility with 720p tv's". But it made no difference compared to 3.1. There is no settings in the TV which could fix this.
Is there anyway to get the image fit properly on the screen?
what you are experiencing sounds like regular overscan. Alot of the TVs out there do it, and it's something that stuck around from the analog era.
You should look for a way to disable overscan on your TV. look in the menu or play with the aspect ratio button.
My LG works ok if I set the aspect ratio to its '1:1 pixel' mode.
If it's indeed overscan, then your TV is to blame, not your pad.
Edit:maybe the eeepad has an overscan-compensation. I can't look now. But then your pad would be compensating for your TV screwing up the image. So fixing it onyour TV is still preferred.
I've had absolutely no problems connecting the via HDMI aspect ratio on my Sharp TV, aside from probably a 5-10 ms input lag on the screen for playing video games, which is most likely a problem with my TV.
My Sharp has aspect ratio settings like stretch/native/zoom/etc to ensure that the entire image is displayed.
I'm pretty sure its your TV has these settings, since most HD TVs should. You should be able to play with aspect ratio the image settings on your LG until it fits.
Cheers
Thanks for the replys. The specific model for the TV is LG 50PC55 (which is about 3-4 years old) if it makes any difference.
Anyway I looked throught every possible option from the TV which has anything to do with the image. No help there. Aspect ratio is the only thing which at least does something but unfortunately there is only 4 options.
- 16:9 which makes image to strecth out from every corner
- 4:3 which adds black bars to the sides but image still goes over from top and bottom
- zoom1 and zoom2 which both makes things even worse
So doesnt look very promising. I hooked up transformer on my fullhd Benq computer screen with HDMI and that works perfectly. So yeah maybe the problem is on the TV and/or its 720p resolution and the lack of options to adjust the image.
If anyone can figure out any solution that I can do on the transformer to adjust the ratio and possible get it working it would be much appreciated.

Hdmi out

Hello,
I bought a mini hdmi cable.and although I have image on tv the colours are not that good and the aspect ratio a little bit weird.
Is there any way to edit hdmi settings?
Sent from my HTC Desire using Tapatalk
I too have this issue, and I have a 2010 top model Samsung LCD HDTV. I've looked around and couldn't find any settings for this. Either ASUS or Google (android) needs to implement HDMI out settings. In the meantime, I suppose we could play around with the color settings on the tv itself for a temporary solution.
I have an Lg 42 from 2ish years ago, it's not top spec, but fairly cheap at the time.
I have a setting on the TV to change the way it scans the input and therefore correct the aspect ratio. it's a function called 'Just Scan' instead of 720p, 1080p etc.... I had to use this when I had a windows7 media center and I was missing the taskbar at bottom of the screen.
This TV also has ability to change colour/brightness etc... settings for each input, so hdmi1 input can have different picture settings from hdmi2 input and so forth
So do check to see what can be done on your TV settings to make it play nicer with the Transformer.
I also have some occasionnal problems when connecting to my 47" TV,mostly the honeycomb status bar is cropped at the bottom.Don`t know if its a problem with the tv or the tf.Maybe a software update can help with those issues...
try changing the aspect ratio on your TV to Point by Point. I had to do that on my TV for my PS3 and my laptop.

[Q] HDMI Changes usable screen space?

Kind of a weird problem, and I'm not sure if I'm the only one it happens to. If I plug the Transformer into my TV to say, play SNESoid on the big screen, my sixaxis controller stops working. This only happens when I'm using touch profiles within the sixaxis app. Tried to figure out why, and found that my usable screen space changes as soon as I plug the HDMI cable in. What I mean is, I get a "dead" space between the bottom of my display, and the action bar at the bottom of the screen. Tried two different brand TVs, different cables, different roms, and different kernels and the problem persists.
I know I'm not fully explaining this, because I can't figure out how to put it into words. If no one has figured out my ramblings by the time I get home from work, I'll take screen shots of the problem and post them up.

I heard that the newest OTA stock update helps. ICS may help. I hear that revolver new update helps but not for my tv at least. I've also heard there are a few new and updated kernals that solve the problem of dead bar space. I have an AOC HDTV so i am probably screwed.
However, turn off touch profiles. You don't need them for emulators. I've played S3&K several nights with the HDMI cable and six axis app with ps3 controller and it works great. I even make the L3 button access the task bar menu so I can load saves and save easily. Very useful for those pesky super emeralds. I have not dabbed with the touch profiles yet so I don't know.
the hdmi output gives out 720p feed and increases the size of the system bar from whatever size it was to 80px high leaving 720px height usable to apps which will resize them and throw off your touch profiles
Ok... so it is a known issue... good. Any idea if the Prime suffers from the same problem?
I would turn off touch profiles, but i cant stand not having analog control in N64oid

its not an issue it is just that most tv's have a 16x9 resolution so having it use a normal resolution will assure that there are no black bars on the tv

Well, you're right, the issue is not the tablet.
[rant] The issue is that my tablet and my laptop are 16:10... My TV is 16:9. My bluray movies are 2.39:1. Half the content on cable is 4:3. On top of that, it would seem no one knows which aspect ratio to scale their content to.

[Q] HDMI Issues Resolved in 10.6.1.15.3?

Hi everyone,
I'm looking for confirmation that the HDMI issues introduced with Asus' first release of JB 4.2.1 (10.6.1.8) has been resolved with 10.6.1.15.3.
Specifically, the issues that plagued me were:
- HDMI to TV output limited to 640x480 resolution.
- Missing HDMI Scaling/Cropping mode options.
I never even got around to testing HDMI audio before I decided to go back to JB 4.1.1, but I have seen the reports of HDMI audio issues here on this forum.
If anyone who is on 10.6.1.15.3 can confirm that these issues have been resolved, please post here!
I miss outputting at 1080p / 720p (depending on the TV) and cropping mode, and I'm not willing to update to JB 4.2 until these options are once again available to me, so I would really appreciate your feedback.
Thanks.
Audio issue fixed here for me - it would work on one screen but not on 2 others before the latest update
No cropping/scaling options in settings for HDMI, just 3D Output (if connected to 3D screen).
I've only had this a couple of months and started with JB so I don't know what other options there may have been before.
According to the screen it is receiving a 720p signal.

So, I took the plunge and upgraded to stock JB 4.2.1 (10.6.1.15.3). The output to TV does now go to 720p, but I am still missing the HDMI cropping and scalling options as you have indicated.
It looks like I'm sticking with JB 4.1.1 for a while longer...
Aaron, the cropping mode basically crops the status bar off the bottom of the screen on the TV, and gives me a "full screen" experience, which is great for when I'm playing emulators or watching videos and want some screen real estate that would otherwise be taken up by the status bar. And, it eliminates the bars that would otherwise appear on the left and right sides of the screen.
Thanks.
Hi!
ASUS Transformer Pad TF300T with TV FullHD Panasonic TX-P42VT20E
I still have the HDMI (resolution) problem:
with the previous firmware (Version 10.6.1.8 WW SKU) the HDMI signal was at 1920x1080p (1080p) always with the two vertical black bars in the left and in the right.
Now, with the latest firmware (Version 10.6.1.15.3 WW SKU), the HDMI signal is at 1280x720p (720p) always with the two vertical black bars in the left and in the right....
From what I see, even if the signal is 16:9 I still see the two vertical black bars in the left and in the right as if it were a 16:10 video format.... Then the HDMI signal is 16:9 but the video format is the same of the Tablet, then 16:10.
This is a very big problem to watch movies and youtube on TV!
At now I did not find a solution to solve the HDMI scale problem. The only workaround that I find is to lunch this command from a terminal:
am display-size 1280x720
this command will solve the HDMI scale problem, the HDMI output and also the tablet screen output will goes to 1280x720 (720p) resolution.
Now I would like to understand if there is a way to set the HDMI output at 1920x1080 (1080p) as the the previous firmware Version 10.6.1.8 works.
How is possible to "force" again the tablet to use 1080p resolution to the HDMI output? There is a conf. file into filesystem where this settings is setted?
Also, with Android 4.1 oldest firmware what was the HDMI output resolution? 1080p or 720p?
Thanks!
I don't know if anyone noticed but the HDMI output is streaming 5.1 PCM signal even if your content is only using 2 channel audio stream.
This will generate problem when you connect your tablet to a 5.1 Home Theater system and you will only get sound from front L/R speakers.
Hope Asus can fix this.
