Force Reduce Android Screen/Output (MHL) Resolution - General Questions and Answers

Hey All,
Please excuse the noobity.
I'm trying to connect a Microvision Show WX+ PICO Projector to the MHL port of my Galaxy Nexus or Asus A500. I've found the appropriate cable but the Android output is locked at 720p whereas the Projector accepts a max of 480p.
Question: Is it possible, through a ROM or any other means, to force switch a) the entire device' resolution to 480 or just the MHL output, as you might with a multiple screen setup on a Desk/Laptop?
Thanks so much in advance!!!

No solution from me I'm afraid, just a bump! I'm interested in this because on my galaxy note everything gets really slow when using mhl. It would be great to lower the resolution to make everything a bit smoother.
Something which might also help me but not OP would be if the display was rendered only once. Since my TV says it receives a 1080p signal from the phone (and the phone screen is obviously not displaying 1080p) I must presume that although the content of each screen is identical, they are actually rendered separately.

Mhl cable fps limit?

Hi,
I have bought a mhl cable, but when it is connected to the tv, shows 24 fps limit.
Its good for watching vodeos but in games it should be 60 fps.
So what can i do
Thanks

I don't think the phone can handle 60fps on a big TV. I've tried GTA3 connected to a 42in TV and off course it was choppy as ****.

TV's will only play at 24fps thorugh HDMI unless you have one of these crazily high hz ones

In addition to which our Sensation seems to lack the horsepower to play anything via MHL truly smoothly as well. If you want to experiment for a laugh, download Electopia game/benchmark from the Market. When you start the app you will be asked if you want to run it at WVGA or full screen. Start with WVGA, then, on the next screen select 'benchmark mode'. After it finishes (about a minute) it will give you a score in cluding the average fps. Now go back and do the same full screen (it will be lower). Now go back and run both tests with the phone connected to the tv via MHL and you will see it's even lower. I get:
WVGA: 39.75 fps
960x540: 33.68 fps
WVGA connected to tv via MHL: 29.62 fps
960x540 connected to tv via MHL: 25.09 fps
Bear in mind these are averages so it's likely that frame rates are dropping substantially below this at times. In addition, in percentage terms, those framerates are a world apart. At least I can now quantify why Shadowgun and MC3 are a bit frustrating via MHL.
I'm hoping that as the newer phones come to market this year journalists will get their backsides into gear and start benchmarking these kind of factors for us ; ) For those of use that want to connect our device to a tv then control it via bluetooth keyboard and a mouse (essentially use it as a little media pc for light gaming/internet/movies/email etc), this kind of info is really important. Wish I'd known before I bought it. Not sure how well the new 720p screened devices will get on with the extra pixels AND duplicating the image to a tv...

Based on the performance of our phone and what bonesy said above, I guess not. I guess you could try overclocking your Sensation to make it maintain 24fps and see if that helps....
Before I buy my next phone I'll try and make sure it has the power to mirror to a tv smoothly.

TF700T + Netflix + hdmi

I have been trying out Netflix on my TF700 and displaying on a 120hz 1080p Vizio. The sound is very out of sync with the video. This is using the HDMI port on the TF700, no bluetooth involved. During the movie there were several times when the picture became very mottled and blotchy like the video processor couldn't keep up and reduced resolution. Is the poor performance the App's fault, ICS, or what ever.
The Netflix App is so poor it is painful to use. Will be cancelling the free trial just because the App is so bad.

Get wifi analyzer from the market and see if you can choose a better (less occupied) wifi channel. The blotch is typically reduced resolution due to the connection, not the processor. Thanks to prolific hardware decoding, tegra 3 coasts through video.
Can't speak for the sync issue though. Is it in sync when you aren't using HDMI-out?
If you were using MX player, I'd say use s/W decoding for audio out of sync issues. Bit Netflix doesn't let you change those kinds of settings. Do like other poster said and try a less crowded channel.
ASUS hasn't updated the HDMI features on the Firmware version for the Infinity, it lacks a couple options that allowed you to properly fit your tablet to your HDTV's display.
The Transformer Prime has these options in it's latest firmware released several months ago, but these options are absent in the Infinity.
My only hope is that these issues are resolved once ASUS ever get around to releasing Jelly Bean for the Infinity.
I have the same problem with my new infinity. The prime it replaced worked very well with the Netflix app.
I do not see similar problems with
other video, so far.
BS player as well has great reviews and tons of features

Just tried watching a movie on the TF screen and everything was in perfect sync. The HDMI output appears to be where the out of sync condition is being introduced.
I haven't tried Netflix with the HDMI out. On my Evo 4G, when I do it, it sometimes gets out of sync. You just have to stop, and restart the movie. It works most of the time.
As for Netflix, when in the app, if it's laggy as all can be, go into the developers section in settings and turn on force 2D. It helps significantly. Read it somewhere on here and tried it. Might even help with the sync issue.
Thanks for the 2g tip makes netflix work much better. Scrolling with normal settings is terrible even without hdmi. Works normally after changing settings force 2g.

I did change force 2g to on. Netflix works much better. Voice did sync on hdmi in netflix and YouTube. A little delay on Netflix until stream got going about 1 min. I had forgotten to turn off program running on roku so i had two streams at same time. Since Netflix was almost unusable with 3g excel on and using hdmi, i did not try sync test.

I've found that my infinity doesn't output 1080p on the HDMI. Works on YouTube which leads me to believe its the Netflix app itself. Are you guys using the stock Netflix app or threaD modded one?

When i first hooked up tf i had a small boarder off screen on tv. I changed tv settings to adjust vertically and screen resized properly. I had no problems viewing netflix on hdmi to my tv. Video did not play on tf, but did show everything else.
I recently change my dsl from 1.6 meg to 12 meg. Huge difference. I am amazed that Netflix can stream at slower speeds but quality goes way down. I've read that you need at least 4 to 6 meg for good playback. Problems with playback may be caused by slow dsl.
Test on resolution of tv
Tv shows 1920 x 1080 on home screen of tf. When Netflix plays video tv shows 1280 x 720. Tf is changing hdmi output depending on what its playing.
Hulu plus will not play on hdmi.
Amazon plays through browser standard def.

To remove the bottom on screen navigation keys with HDMI out enabled:
Go to Settings, then click on the HDMI category at the bottom. The navigation bar at the bottom of the screen will disappear and you will have native 1920 x 1080 full screen output on the TV.
It's really weird that clicking the HDMI category / row instantly removes the navigation keys. It would have been better to have a show / hide preference in the HDMI settings pane...

Allshare - selected apps or true mirror, wifi or direct?

In my endlessly circular deliberations between Note 10.1 and Nexus 10 I am now focussing on streaming to TV.
Can anyone answer whether the Allshare adaptor for TV
a Works with the Note 10.1
b Mirrors the screen exactly or only streams selected content (video/music/photos etc)
c Requires a Wifi connection as well as an HDMI and separate power source
Many thanks
a. Yes
b. Yes
c. no yes yes

Excellent, that may have swung it, as rumours seem to indicate that N10 miracast support is not functioning, despite being capable.
I looked at ipad/Airplay but that's over Wifi which means it's largely non-portable.
Thank you
I very much enjoy my allshare. Plus after registering with samsung, they gave me 50% off, so that was nice, getting the adapter for only 50 bucks!
When watching netflix, youtube, or hulu, it will put the video on the tv and you can use the seek function on the note. Also, with the youtube app, you can have the video play in full screen on the tv and do limited browsing on the note, like the related to videos and stuff like that while you are finishing up your current video. I haven't noticed much out of sync with the videos, I think that mostly has to do the my internets at the time because I have had the same kind of issues using hdmi and my laptop. It is soooo much nicer not having any wires to mess with, just connect on demand. It makes this by far the coolest thing, plus the ir transmitter so you can do everything on the note.
One thing I did have to do, after doing a lot of flashing and changing a lot of stuff, not sure if you would be doing the same, but I had to use triangle away to reset my flash count to get it to work, most other people never have to do that, but for whatever resaon that is the only way I got it to work for me
Great. I probably won't root yet anyway. Unless it is required for all share.
I'm going to wait until the official jb update then root after that.
Swype'd at pace from my Galaxy S2
does the Allshare dongle Support Miracast ? possible to connect via Nexus 7/10 to that dongle? or via Windows WiFi direct+special Tool?
kinda sad that the dongle needa external Power And is huge. But Else cool stuff.
If you are referring to the wireless adapter, it works very well and works with hbo go and YouTube. It works well enough that I just went and bought this tablet due to the fact that I used it with my sgs3.

[Q] Miracast Netgeat PTV3000

Hey,
I recently bought the Netgear PTV3000 and I am using it with my Nexus 5. Installation and everything else worked like a charm.
Things I'm wondering about:
- Whenever I connect my Nexus 5 to my TV, the screen resolution of the TV switches from 1080p to 720p. How come? It's supposed to be 1080p.
- In a couple videos on YouTube I saw that Samsung devices dont mirror the screen when stream videos but rather show a UI for controlling. How can I achieve this on my Nexus?
THX in advance!

samsung is probably running allshare to a samsung tv.
how did you get yours to connect at all?
i can't get my n5 to connect to anything with miracast.

MHL performance questions

Hi All.
I recently tried playing Asphalt 8 (with a gamepad) while on MHL connected to my TV.
(Phone is a 1080p Xperia Z ultra)
While it displays, the performance on TV is much slower than on the phone itself (which is perfect)
I imagine this is due to the GPU having to drive 2 displays at the same time.
While there is an app that reduced the backlight of the phone to 0 (an XDA developer)
https://play.google.com/store/apps/details?id=com.nkahoang.screenstandby
I don't think this will help with the performance.
Am I the only one with this problem? is there any way to fix it?
Nobody plays games on a TV?
thanks!
just found a fellow XDaer posted a workaround, that improves the FPS a the expense of resolution
(thanks ERICTHK)

However, still a bit laggy for my liking.
Do newer phones have this problem too? or is it just the old XZU?
