Custom ROMs that support MHL or HDMI respectively - Xperia Z1 Compact Q&A, Help & Troubleshooting

Hi,
before installing a custom Rom to my Sony Xperia Z1 compact I did a lot of googleing to figure out if there's a custom ROM that supports video output via MHL/HDMI. I only found threads saying that MHL is not supported by any ROM other than the stock firmware.
But today I made a different experience and wanted to share this. I tested some ROMs from CyanogenMod and Free Xperia. MHL output was actually working with:
- cm-11-20141112-SNAPSHOT-M12-amami.zip
- FXP-cm-11-20150301-UNOFFICIAL-amami.zip
So both ROMs based on kit kat worked. But I had to plug in the the connector several times and rebooted once before I actually saw an output. It's actually mirroring the screen to an external screen, also rotating as the phone is rotated. But picture was always orientated upright.
On a Dell FHD computer screen scaling was squeezed vertically, on a HD ready TV screen scaling was fine.
I also tested CM12 and CM12.1 but didn't get an output with the ROMs tested.
Would be great if others could also share their experience with MHL/HDMI with their custom ROMs.
Thanks

[Q] [Xperia S] New User, what ROM?

Hi all,
I have purchased an xperia s and intend to install custom ROM tomorrow. I have done a good bit of reading but theres alot of info.
I believe roms based on lastest JB eg cm10? dont have a functioning camera
I believe 1 or more roms based on cm9? does not have a functioning hdmi?
The camera (and hdmi) is important to me. I would prefer to have a modded "hardware" rather than an app such as the cybershot one (I assume an app means the improvements are only seen when in that app).
The only camera hardware mod i can find is "[MOD][CAM]GBXperia S|Video 1080p >20mb Bitrate|720p >15mb Bitrate|>100% Image quality".
This requires 2.3.7.
I would be grateful if someone could point out (via link or name) a 2.3.7 based rom, and kernel, as simple and clean as possible (no bloatware) that has a better performance than stock and would allow me to use this mod. Of course, if i have missed a later/better ROM with optimised camera let me know
Thanks for reading and hope someone can advise, I realise im more of a lurker
CM10 has a functioning camera, however I prefer the stock camera (SONY).
About HDMI, i'm not sure about it, I have no HDMI TV for me to play on, however user reported that it worked (in CM10 thread)
About the camera hardware mod you mentioned, it already included (implemented) in the ICS update if I'm not mistaken, therefore if using stock ICS ROM, the MOD is included.
I do not try other MOD ROM, I just tried AOKP JB and FXP CM10, for me, I like CM10, has the latest function on Jelly Bean.
Wish SONY can release the update asap. haha
If you want CM10 based ROM, install Nova Xperia RC1 and update its kernel to 007. That ROM is great, I didn't find any bugs, except that the camera doesn't record in 1080p.
If you want a stock based ROM install XTXperience v7 and Advanced Stock Kernel... It's based in the latest official Sony firmware and it has the look of Xperia T or GX, all depends of your taste
I'd recommend you try PAC ROM.
HDMI isn't as well supported in AOSP than the Stock ROM. In CM9 and CM10, it works and puts out a 1080p 30 Hz signal, but is noticeably laggy. Watching movies works ok-ish, Vsync problems are noticeable though and some frames are dropped because of this - way more fluid on a stock ROM, which lets you select different output modes as well via the service menu (I choose 720p60). AOSP also only has the option of sending out the video layer of Hardware-decoded video directly, meaning true 1080p, but no overlays including soft subtitles. Stock offers both, 1080p output or mirroring of the 720p screen, which makes soft-subs on HW-decoded video possible.
As for the camera, Panorama is broken in CM10, and video recording is 720p max, otherwise it works fine.
If these are no issues for you, go for a CM10 based ROM - more customizable. Otherwise pick a stock-based ROM.
I have the Acro S by the way, but that phone has the same camera. The HDMI issues are universal in AOSP ROMs and almost all Stock ROMs for most phones - Sony are as far as I have seen the only ones to bother optimizing the HDMI output and offering some options for it on their phones.
Thread closed. Unfortunately "what ROM", "best ROM" type threads aren't encouraged on the forums as everyone's opinion differs and what one person may tell you another will disagree with so the only way to find out what's best and meets your requirements is to try some for yourself. Most, if not all ROM threads should have a changelog with what's working/not working so you'll be able to rule out any that don't have what you need and those that don't state issues may just not have had anyone report them.
Thanks

[Q] Change HDMI output resolution on Tab Pro 10.1?

Hello everyone.
I am now the happy owner of this wonderful device. One thing that annoys me tho, is that when i use my official Samsung MHL cable to output HDMI to my TV, it doesnt adapt to my full hd tv with aspect 16:9, but still keeps the 16:10 resolution of the tablet, which results in black boxes on each side of the screen.
I have tryed different resolution changing apps, but with no luck. They both resulted in a boot loop of my device, where i had to hard reset to stop it.
Is there anyone who had any luck with any apps, scripts, roms?

I think because of the higher resolution of this tablet, and the norm of 1080p HDTVs, you are going to get some cut-off points when mirroring the display.
LineageOS supports both resolution changing apps and MHL.
Edit: That specific rom is for the tab 8.4. However, if it helps, it seems that samsung-based roms are the problem. CM-based stuff seems to have worked for at least one other person that I saw.

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:

Never used these before but have you got a PC monitor with Hdmi?

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:

Couple of questions (can't record in 720p & home screen speed indicator)

Hi all, couple of questions..
I have this (http://www.aliexpress.com/item/Seic...ecorder-Vehicle-DVR-G-sensor/32668454402.html) usb dashcam hooked up to my MTCB head unit.
When running in 5.1 I was able to get it to record video in 720p but now that I have reverted back to 4.4.4, I am only able to record in 480p.
Any idea why? Using the same app in both (dailyroads voyager).
Or any link to a good usb cam that works well with 4.4.4
Quality comparisons below;
Android 4.4.4
Android 5.1
Second question. I installed this (http://forum.xda-developers.com/showthread.php?p=66620979#post66620979) home screen but the speedometer widget doesn't display my speed. Do I have to activate it or anything? It just sits at 000 all the time. It's the same on the screensaver.
This has probably been answered in that thread already but it's a pretty sprawling thread at this stage and hard to navigate.
Just came across a possible solution for the speedometer. Seems to be an xposed module needed to go with it. I will test and report back.
