One simple question from me:
Are android 4.0 devices able to connect to monitor via HDMI at resolution higher than their native monitor resolution?
In other words, is there any way to modify the output resolution in ICS as it is for example in windows or ubuntu etc?
I ask this because I have a Xperia Neo V which is to get ICS in April and as far as I searched, I found out that when connecting to monitor, the output resolution is actually 854*480 upscaled to 1280*720p.
If ICS give me the ability to connect to monitor at true 720p, I am planning to save me the buy of a laptop for use in my vacation house through summer!!
I will only need the SE docking station...
Imagine that.. isnt that lovely??
Hi there!
Hope someone can help me here...
I have a 10" Teclast A10t (Allwinner A15 CPU, based on Cortex a8) running ICS which sports an HDMI Output.
Now, I'd like to use it as a upnp client hooked up to a widescreen 1080p display via HDMI,but the picture I get on the big display is always 4:3 which ends up being either an incredible waste of display when playing widescreen media or quite blurry and overall fugly when stretched to fit the screen using the display's settings (and, of course, it's stretched which makes watching movies not exactly enjoyable).
Anyways, I can't find an option to select the AR of the HDMI output... Does anyone here know how to do the trick? Am I overlooking something, is there an app for that (tm) or am I just f*cked and it's not achievable?
Tried CM9, CM10, googled around for hours qnd searched the market but to no avail...
Thanks in advance

You can do this with AOKP I believe.
You can use Resolution Changer to change the resolution from 4:3 to 16:9 (https://play.google.com/store/apps/details?id=com.lugalabs.resolutionchanger&hl=en).
Note: The app REQUIRES ROOT.
I had the same problem as my 4:3 tablet has an HDMI output, yet when connected to a 16:9 TV, the picture was stretched making circles turn into horizontal ovals. I also tested this with Chromecast and it worked well, too.
The SecondScreen app (free) and a bit of additional research let me find a way of getting this working without having to root.
This solution will work well for those that want to use a 4:3 tablet (e.g. 9.7" 2048x1536) with HDMI and/or Chromecast/Miracast on a 16:9 format screen (TV/projector) and have found the picture looks squashed (egg.shaped instead of round). This will fix those problems well WITHOUT needing to root. It just needs a little effort to install this properly.
First of all, you need to install SecondScreen on the tablet (or smartphone).
Then you need a PC (preferably Windows 7 as anything higher needs additional security steps) with Google Chrome installed and a bit of patience.
Follow the instructions on this page up to and including step 6:

For step 7, use this exact command, instead: pm grant com.farmerbb.secondscreen.free android.permission.WRITE_SECURE_SETTINGS
After that, you can proceed to setup the app, there are now no more root issues and it works well. I recommend setting up profiles with 160 (for smaller and more text on screen) and 240 dpi (normal size). If you go higher than that, you start losing icons on your desktop that have to be setup again.
Alternatives:
If you just want to play videos properly, use VLC Player as that natively sends the videos in the correct aspect ratio to the TV (second screen method). This also works well with Chromecast.
For images, Google Photos does have a cast button, that will then display the images in the correct aspect ratio on Chromecast - this will NOT work with HDMI. Showing still images with Chromecast is somewhat frustrating, as the pictures are often pixelated at first and by the time they look good, the slideshow goes on to the next picture. HDMI is MUCH better than Chromecast in this aspect. Pity that many Tablets do not have an HDMI port.
My recommendation is clearly to use the HDMI port and this solution, when showing videos and images. HDMI is much easier to use (just plug in the cable), as well. If your tablet does not have an HDMI port, Chromecast is just as good with videos, but worse with still images. Chromecast also requires a local Wi-Fi router and internet connection to work. Miracast does not require a local Wi-Fi or internet, but suffers from pixelation the most. This could be OK for static slides, but videos rarely look good on Miracast.
Hi Android gurus! I have nut to crack and I was hoping you could help me with that.
I want to use my MK802 IIIS with a projector but I am having aspect ratio/resolution issues. Namely my projector supports 800x600 and 1024x768 but on my Android stick I get chose 1920x1080, 1280x720 or 720x480 (Settings->Display->HDMI modes). The stick has only HDMI output and I am using a cheap chinese adapter to connect it to the projectors vga input. For example with 720x480 I do get the picture but at left side a slice of it is cut off.
Ideal would be if I could set the video output to 1024x768 (with 4:3 aspect ratio).
So, how could I change it?
Is there any Xorg like solution, that is, add resolutions by editing some conf file?
I have limited knowledge on Android but I do know java and I am willing to digg in and so all answers and solutions are welcome. Of course it would be great if there would be easy fix but if you think I should go nuts and create a custom ROM, build custom firmware... I will be excited to hear that.
Anybody?
Where how??
I'm trying to find an answer to the same thing, Also an android stick but also in general for Andoid.
Besidess the menu's in settings, which can be limited, there must be a way to force a specific resolution.
And I don't mean "simulate" a resolution change by changing the Density/DPI
Someone must know, and It must be easy, please share
Hello everyone,
I'm looking for custom ROM which has default HDMI output set as 720p. Now I am using stock French rom (without knox) and my Mega hdmi output is 1080p/30Hz because my TV support FullHD resolution. It causes a lot of performance problems and practical usage is reduced. So I have question which ROM support 720p by default or has additional tv settings to change output resolution. I didn't find any solution to change tv output. I'll be glad for help.
I just bought the official Smasung usbc-hdmi adapter for use with my Galaxy Note 8. I am looking for a way to set the output resolution since it goes to max by default and since my TV is 4k and i get 25 with this adapter (hdmi restriction via usb due to rights) i am looking to set the resolution to something lower. I would also appreciate a setting where picture is only shown through my TV and does not play on my mobile as well. Its distracting and a waste of energy as well
