What are the advantages of having a smaller TV as a monitor vs a traditional monitor? Assume both are 1080p and the same size.
The tv has a remote.
TV's scale different resolutions better too.
Smaller TV? Why smaller? I use a 32" one as my monitor.
Another advantage is I can flip a switch and it turns into an Android device

Im thinking about adding a 7" lcd screen to my truck to act as a backup monitor and a larger lcd for GPS. I'd like to connect my Captivate to the lcd and using it for larger, set top viewing of the gps.
Would this work fine in terms of using the video out for gps only? http://www.ecbuys.com/car-lcd-and-c...-tft-lcd-car-headrest-color-monitor-p-52.html

Standard TV video - is 480 lines of resolution - so anything that can emulate a tv monitor (it has TV video in) should display fine. You will get the entire Captivate desktop on your TV - every move to every app is shown - just like having a bigger phone - but you have to touch the smaller screen.

Perfect that is what I need. I will be using the larger screen just to view the GPS and view the video player. I have microsoft sync in my truck and it streams bluetooth audio superbly, but it doesnt show who the artists is on the radio screen. So having a larger lcd on the dash for viewing song info/google navigator, pandora, and using for a backup camera would be great. I did a mockup of how big it would be and where I would put it here:
http://www.f150forum.com/f7/has-anyone-thought-aftermarket-lcd-upgrade-67384/
I think this would be a pretty sweet setup!
one thing to keep in mind - you will want some type of rotation lock feature - this is built in to 2.2. The autorotate is copied to the external screen, so portrait mode on the phone will give you black bars left and right on the right on the screen. You will probably want to lock the screen in landscape mode when connected to your monitor.
Ah yes I am running Cognition Beta 2.2. so I have the option. Good point
I tried the tvout with the offical hmdi adapter but it mirrors the tablet including the system bar, and since the resolution of the tablet is 16:10 and not 16:9 I get two black vertical stripes at both sides.
Is there a way to change this behavior? Like a full 16:9 or a 1080p out?

You'll need to change the settings on your TV to stretch the picture or zoom it, most TV's have a setting to automatically do this to hide black bars, the only problem is it alters the shapes, people end up with odd shaped heads etc
So basically there is no way to play on a tv a 16:9 fullhd video or a slidewhow without status bar? I mean, is mirroring the only one mode?
You can set this up to hide the status bar, but 16:9 is always going to be an issue as the tablet is not 16:9
Yes, but still tvout is a limited feature since I can't have an extended desktop or i.e. a slideshow played on tv while working on something on the tab...

Hang on......so you want to play a video to the TV in HD widescreen while still doing something on the tablet ?
I'm pretty sure there's no Android devices that do this
A kind of... My first aim is to play a slideshow on a tv in full screen mode, while seeing the slide's tree on the tablet and choosing which one to show in full screen on the tv.
Second aim is to disable tablet video and show only tv. It would be nice to play a 3d game on the tv, but as long as the video is doubled fps are so low that it's unplayable.
FPS won't be doubled as all you're doing is doubling up the video output, not the data going through the GPU, there's plenty of video's on youtube of folks using MHL adapters to connect to a TV to play games
Yes fps won't be halved but, since a tough game is very cpu intensive, doubling the video it lags a lot more the tablet. My tablet is much more laggy even simply swiping on the home screens or app drawer when connected to a tv.
Flash motley kernel and overclock to 1.4
I believe a Nexus Q will let you send video from the tablet to the TV whilst doing other stuff on the tablet, but it costs quite a lot.
Definitely hear some unrealistic multitasking wants. Also, doesn't ICS improve hdmi out options as far as full screen video, not just mirroring?

The Galaxy note 10.1 has this function in the movieplayer to only show the video while controls are shown on the tablet. This is exactly what you are asking if i understand you correctly.
I'm also looking for more possibilities in this area. Being able to see the picture Gallery while only showing the last picture (or non at the start) would be amazing!
If i find anything i will share it here
I realized last night that my 1920x1200 display is scaling the Chromecast 1920x1080 signal to a full 1920x1200 resolution causing the entire display to be stretched vertically.
When hooking up the same display to my PC via the same HDMI port at 1920x1080 resolution, I get a 1:1 pixel mapping with black bars on the top and bottom of the image. Is there something in the image source that specifies whether to stretch or use a 1:1 pixel mapping? I went through all the settings on the monitor and nothing will give me the proper aspect ratio.
Same here, have you found a solution? It sucks!

You sure your TV isn't set to Stretch as opposed to normal?

Have you double checked all scaling options of your display? This user contacted Google to let them know of the same problem:

But was this bug ever fixed? Answer: No!

I just plugged the Chromecast in, and it updated (had been sitting on the shelf for a while). After the update, the same problem is exhibited. I have 2 aspect ratio options in the monitor settings, "Full" and "Fit". Both provide a 16:9 1920x1080p signal stretched to the 16:10 1920x1200 resolution.

The other way around: If you have a 1920x1080 display and want to mirror the display of Android device wich has a 1920x1200 resolution, use this app the app "SecondScreen" (https://www.xda-developers.com/cast-device-second-screen/) to set the resolution to 1920x1080 before casting to the Chromcast.
Its goal: "Second Screen aims at providing you with a way to properly cast your screen so that it looks is best whenever you are showing it off to your friends and family. It does so by allowing for a user selectable resolution and even DPI in order to take full advantage of your TV."
Chromecast2 on a HP 1920x1200 display
Louer Adun said:
Yeah, that's what it seems I need is a 1:1 pixel mapping. However connected to my computer this monitor will have a letterbox when set to 1920x1080 and the expected letterboxing.
Please note I only tested this with the first gen Chromecast, so maybe this isn't an issue with the second gen units.

I tested the Chromecast2 on a HP 1920x1200 display. Pixels are mapped 1:1 with the right display settings. I don't have a Chromecast1 to check with this display.
Both the nexus 4 and the nexus 7 (2013) support slimport, which is very useful for mirroring the device to a big screen. However, neither device uses the standard 16:9 (1080p) aspect ratio. As a result, you end up with some cropping on a 1080p TV. For the nexus 4 it is even worse, since it outputs 768p upscaled to the TV's resolution.
However, the flexibility of android allows us to manually change the native resolution. In a console, we can type the command:
wm size 1080x1920
and the resolution will change. In the device screen the new resolution will look odd, however you now have true 1080p on the TV. To get back to the default resolution you type:
wm size reset
This solution works, but it is not very convenient. So I made two profiles for tasker, that automatically change the device resolution upon the connection of an HDMI cable and reset it when the cable is disconnected, thus automating the whole process.
I 'm attaching a screenshot of the two profiles, as well as a zip file so you can extract and import them in tasker.
In summary,
- you need root
- the HDMI plugged profile
reduces the device brightness to minimize battery consumption
increases volume
sets resolution to 1080p
enables WiFi
sets display timeout to 10 hours
activates display rotation
- the HDMI un-plugged profile
sets auto brightness back on
resets screen resolution
sets display timeout to 1min
These are optional settings that I found useful to automate, but they are all optional, and you can tweak them once you imported the profile to tasker.
I hope you find this useful!!! :good:
Hi all. For games that do not support the second (i.e. built-in) display, is it possible via some kind of software to have it zoom in on a portion of the main display? For example, displaying only the map or a health bar of a FPS game? The functionality is just like the new HP gaming laptop I read about in 2019 that has a smaller second mini-display above its keyboard which has custom software to do just that.
Thanks!
