Fix the MHL TV out resolution

I originally have a Note 8.0 but also use a friend's note 2 sometimes for giving video out to a Projector. So, I use an MHL to VGA Converter and a 5pin to 11 pin adapter.
The problem is that both the devices randomly pick a resolution everytime I connect it to the projector. Sometimes 720p, sometimes 4:3 VGA. I just want to fix on a resolution. VGA only rarely comes up, but I actually want it because the projector is natively 4:3 and fills up the screen better with it.
Is there anyway I can select the VGA resolution permanently? Like selecting a resolution in Windows?
I found a libhdmi.so file on the Note 8.0 which contains all the info. About resolution, it has everything from 640x480 to 1080p modes. Is there anyway, I could modify it to get the same resolution all the time?

Get slimport to output 1080p instead of 1200p?

I have a nice 1080p projector I'd love to drive with the Nexus 7 over Slimport. Performance is great, but the picture has letterboxing on the left and right due to the 16:10 aspect ratio of the tablet. Is there any way to get the Nexus 7 to output only the top 1920x1080 (ignoring the permanent soft button bar)?

Yes, there are ways. Unfortunately none of them's easy. One way is to change the screen resolution but that requires root. The other way is to add support for external display in a video player app. As of 4.2 app developers are able to detect and handle mutliple displays at once. So it's for instance possible to detect that external display is attached, discover what resolution it supports and output video to the external display at a native resolution. I am quite surprised that the native video player does not support that. It shoud work by default that way.

Could you please tell me which slimport cabel you are using? is it SP10002? I am struggling to get a perfect one

[Q] slimport to hdmi / custom screen resolution woes.

I've recently bought myself a slimport adapter so I can hook my g pad up to a TV (1920x1080).
The g pad appears to downscale its native resolution of 1920x1200 to the resolution it outputs over hdmi (in my case, I'm outputting 1920x1080).
As I'm displaying movies on my g pad's screen @ 1:1 aspect ratio, this downscaling from 16:10 to 16:9 obviously leads to distortion.
To remedy this, I'm using "wm size $resolution" to change the g pad's resolution to 1080x1920.
The problem I'm having is that the window manager is doing some stupid stuff with the virtual softkeys in landscape mode at this custom resolution.
See screenshot here:
@ default 1920x1200
@ 1920x1080
Does anyone know of a solution to this problem?
How do people successfully use the g pad's slimport to hdmi functionality when the TV is a different aspect ratio to the device?

I'm still stuck on this; is this a flaw with the stock rom for which there's no known solution?

You have to change dpi settings too. Can see instructions here or use Resolution Changer Pro from Play Store.

MHL Cable Help (M7SPR)

2016/2/21-
I am pleased to say that I was able to get my phone and TV out at a 1:1 while using a Bluetooth controller (PS3 Six Axis). I changed my Rom with Candy5 and had the phone set to performance on the CPU and GPU. With this change I was able to get a better input rate and the TV out rate with little to no lag. This lag is most noticeable in Minecraft at max graphics, but on low graphics, the game has minimal lag. Playing online games such as RR3, Nova 3, Modern Combat 5, etc. are playable but are not recommended due to small display lag. Single player games such as BOZ, Dead Trigger, Minecraft, Shovel Knight, etc. are very playable but have slight display lag.
To put in short:
Less graphically intense = better Display output/ FPS
Also check your TV for gaming modes/ options
Thanks to Saf98 for the tip :good:

I bought a MHL cable for my phone to game on my tv but there is a noticeable amount of display lag (lag from when I push a button and it takes a while to mirror the input to the tv display but not the phone display).
I've been wondering if anyone else has had this problem before with a MHL cable of any sort and if you did, were you able to fix it and how?
This is the MHL cable I have but I didn't buy it online, this is just for reference:
http://www.cellularoutfitter.com/ht...CA&utm_medium=CSE&CA_6C15C=120153940001509368
People might ask me this so I'll answer myself:
Q: Did you see if the cable was compatible with your phone model?
A: Yeah I did, it outputs video and audio fine with no lag on the tv display. I also looked into this cable prior to buying it to see if it fully worked.
Q: What resolution is your tv and what resolution does your tv recognize from your phone?
A: 1080p both ways.
Q: Are you on a stock rom?
A: No, I'm on PAC-Rom 5.1.1. Stock also had the same issue.
Q: Have you tried changing your device's resolution to see if that eliminated the lag?
A: Funny you ask, I have but it instantly reboots and loops when I do, both on stock and custom roms. Don't know why, does this happen to you?
Q: Does the charger connected to the MHL cable supply enough juice to it?
A: Yesh it does, it's a standard 5V samsung charger (Not a quick charge one nor a usb-to-powerbrick one).
Q: Do you have a lot of apps installed on your phone?
A: No, I debloat a rom to a safe max (Removing/Disabling unnecessary apps like Live wallpapers, FM radio, stock browser, calendars, stock email, all G-Bloatware).
Q: What is you phone's average free ram amount?
A: About 1.3 Gigabytes.
Q: What are your kernel settings?
A: CPU: Smartmax with stock cpu clock
CPU Voltage: Global off-set of -50
GPU: Stock 400 mhz with Simple Gov
Wake Gestures: Full screen DTW and STW/S
Z-Ram: 1000MB
I/O Schedulers: Fiops Read-ahead at 4096kb ~4mb
Any help would be appreciated :silly:

Unfortunately I do not, it's a standard RGB/ VGA monitor. To my understanding, you can change the refresh rate on HDMI monitors to eliminate display lag right?
I've also tried to see if I could try to change the refresh rate on my tv but it doesn't seem that I can.

I'm not sure then.
Edit : it doesn't show HTC one so it may not be supported, I've seen some on yt and it works but it might just depend on the quality of the product. Isn't there any mode on the tv that you can change.

It does support it, I've had no problems with it. Video playback is 1:1 with no audio lag at all. Music playback is also 1:1 with the rare audio warble from the ROM itself but other than that it's perfect. There is a slight UI lag though but that's because the phone is outputting 1080p on two displays.
No there isn't unfortunately, I've been allover the tv menu from picture and display yet nothing was found on refresh rate or other things on quality. It's ~2-3 years old, pre-smart tv era; basic 32" Vizio led tv.

A bit but it's more of a tutorial of how and what settings do. Also this is for a 4k Ultra HD Vizio with a different/ newer firmware than my tv and higher resolution, thanks for the suggestion though. :good:

Enable Galaxy TAB S7/S7+ 4K resolution (Using ADB)

I am unsure if this thread belongs here. Kindly let me know if it doesn't or please move it.
I was wondering if the TAB S7/S7+ would let me play YouTube videos on 4K using the native app but unfortunately it doesn't for obvious reasons using stock settings.
So I figured a way to enable this using ADB. I am unsure how much this affects the battery life since I am still testing app compatibility and power usage.
ADB Commands
1. To set 4K resolution -
adb shell wm size 2400x3840
adb shell wm density 1024 (or whatever suits your eyes, mine is 1200)
2. To reset to default -
adb shell wm size reset
adb shell wm density reset
So if anyone's interested all you have to do is -
1. Download minimal ADB and install it if you do not have ADB installed.
2. Open Command Prompt in the ADB folder by pressing Shift Key and selecting the Right Click option "Open command prompt here".
3. Run "ADB devices" without quotes and accept the prompt on your device (Your device must have USB debugging enabled, if you don't know how or have it enabled you probably shouldn't be doing this).
4. Run the above "To set 4K" commands to set the display resolution to 4k.
5. Clear the app data of Youtube and restart the device.
6. (Optional/Reset) To reset the display resolution to default, just run the 2nd set of commands.

Not sure this is actually making the screen dislay 4k.

It doesn't actually MAKE your screen 4k as the display only supports 2k. The device renders everything in 4k and then outputs it on the display just like what Retina Displays or Nvidia DSR (Dynamic Super Resolution) does.
Just in case you want to actually make sure everything is running in 4k, you can simply try running a 4k video on Youtube which otherwise you cant!

Right, so what's the point? The 4k video doesn't look better on a 2k screen.

Since DSR and Retina Displays already exist, I believe there are some advantages. You have to try it to believe it. The displays feel a lot sharper, edges feel smoother, fonts look amazing, overall it just looks good on the huge display of my Tab s7+.
Coming back to that I need to ask you, did you try this before asking me the POINT. Coz I feel if you would have, you wouldn't be asking me this!

Yes, I did, and it looks no different. It's a 2k screen, enabling something to load a 2k screen with 4k will make no difference. Not trying to argue, just saying, it's pointless.

I accept it doesn't make any greatly significant difference but then its subjective. It was just an experiment and I wanted to try it. There are many people out there who always want to run youtube at 4k, this was simply my answer to that problem, although it has its own downside and implications.

Thanks for figuring this out! Often 4k will look better on a 2k screen than 2k on a 2k screen.
This is because pixels from youtube don't always line up perfectly to the tablet pixels and you end up with a resolution less than 2k when you have it set to 2k. When you stream at 4k from youtube, the content is delivered with smaller pixels and ends up looking better on a 2k display.

Thanks for this going to give it a try on my 7 plus.

it worked now i get the option to 2160 resolution, it does look sharper.
good work thanks very simple

Hey
When i use the command "densiti" my screen become wery BIG otherwise the "size" resolution is great
is that normal ??

There's also Newpipe to get 4K Youtube without hacking. As a bonus, it also gets rid of the ads.

Does this work on Netflix? Will the maximum resolution on netflix and prime video change to uhd?

What the Implications and Downsides to this?

The point is higher bitrate. Youtube compresses videos so much so 4k will have a much higher bitrate than 1440p and look better.

Btw, use youtube vanced for 4k but use sparingly as it blocks ads. I wouldn't suggest using it very often because it doesn't support creators

What about on Samsung Dex or any kindof screen mirroring on external monitors? Any way to get the S7+ to send more than 1440p to an external monitor through any means?
For instance if you set the resolution to 4k with ADB, and then you mirror your display via a [email protected] usb-c / hdmi cable to your 4k screen, will the screen receive a 4k signal?
Can anyone (Stryker_Echo9er) try that?

If you have unlimited data and an old device lying around (all it has to be able to do is run the official Youtube app), you can leave the video playing on that device with ads while you watch on your S7 or whatever without ads. Best of both worlds, the only extra you pay is that little bit of electricity to run the other device.

YouTube now natively supports 4K HDR.
Now you can watch high quality 4K YouTube videos on Android phones
Support for 4K HDR playback was only there for iPhone users while Android smartphone users were only able to play YouTube videos at a maximum resolution of 1440 pixels.

I tried doing that on my 8-series Samsung TV, unfortunately, it doesn't work on my TV via USB-C (using an HDMI Dongle) or screen mirroring. I am not sure if it would work on displays with a type-c port.

Thanks for trying. But do you mean that it doesn't work at all, as in you can't use dex on your TV? Or does it mean it just doesn't do 4k?
