[Nexus 4 Accessories] 4L3xN3t:
Hi,

I've a stock rooted nexus4 with 4.2.2.

Bought today a slimport adapter marked "manhattan" (barcode766623916653) and it seems not to work, my tv show as "active" the hdmi port I used to connect, deactivate it if I unplug the adapter and already tried to change hdmi port. nothing on the screen!

is there anything I should do except plug the cable into the phone and to the tv to make it work?

thx ;)

That's the only occurrence of manhattan I'm seeing. It looks like he may have gotten it working by going back to stock, which you're already on.. Might be worth messaging him.

I did try to look for the Manhattan Slimport, but it's mostly foreign. It looks just like my MHL adapter, although it says slimport and has no mention of mhl, so that's good.
[Nexus 4 Accessories] 4L3xN3t:
mmmmhhhhhh....thx! I contacted the user, let see if he has some advices.

Tomorrow I'll try to talk with the guy from who I bought it, he said he took this cable just for nexus4, very strange doesn't work. I evend did a search with the barcode and lot of seller seems to have it in their stores...:confused:
[Nexus 4 Accessories] michaelg1030:
Two questions for those that have the device:

1) Does it work with navigation?

2) If you own the device and happen to own an HDMI to composite/AV converter, do the two work inline together?

I know the second one is a stretched, but I am trying to get navigation from my phone to display on my car's headunit.
[Nexus 4 Accessories] Erichhart:
hey guys, I tried 2 different TV's and went from CM10 and now on Paranoid and the output works but not for audio? Is there anything special i have to do?
[Nexus 4 Accessories] karasuhebi:
1. From the looks of it, it does. This guy does it. http://xdaforums.com/showthread.php?t=2241148 If you'd still like for someone to try it out and outright confirm it, let me know.

Try a stock ROM. It works just fine for me with stock. All I do is plug it in and voila, it starts working.

It's probably getting really hot from the combination of charging and the work the phone has to do to decode (and output) those video files. Try not charging it to see if that makes a difference. Also as ziddey noted, it's not really getting hot enough where you should worry since the phone would protect itself against that. If you'd like, you can point a fan at it. It helps.

Yes I noticed that it forces USB charge as opposed to AC charge, it sucks. I seem to remember reading someone on XDA (maybe even on this very thread) saying that they were going to try maybe shorting out a PIN or something to force it into AC charging. I wonder if that works, as I'd rather not mess with my kernel. Regardless, would you mind telling us how to modify the kernel to do this? I'd love to try it out.

For turning off LCD during playback, try Screen Standby # Root (https://play.google.com/store/apps/details?id=com.nkahoang.screenstandby) or any other app of that sort. Something tells me it might not work, but it's worth a shot.

I don't think you need to worry about it melting. If I may, I think you're being a bit too worrisome. Like it has been mentioned above, the phone will protect itself. If you'd like, try pointing a fan or A/C vent at the back of it. It helps :)

As an aside, I received my adapter today from Amazon and it works great. I just plugged it in and it immediately outputted video and audio to my TV. Only thing I don't like is that it forces landscape mode. I can understand why it does this, but I was used to using HDMI Out apps on my EVO 4G that allowed portrait mode as well. I guess maybe I'm a bit spoiled but does anyone know if this is possible?
[Nexus 4 Accessories] ziddey:
It's not worth modifying and compiling the kernel unless you're doing that already. But for what it's worth, the pertinent file is at drivers/usb/otg/msm_otg.c -- https://github.com/ziddey/mako/blob/nightlies/drivers/usb/otg/msm_otg.c

specifically, msm_chg_detect_work is the function that detects the charger type and has the following:

if (slimport_is_connected()) {
msm_chg_block_off(motg);
motg->chg_state = USB_CHG_STATE_DETECTED;
motg->chg_type = USB_SDP_CHARGER;
queue_work(system_nrt_wq, &motg->sm_work);
return;
}

where sdp = usb 500ma

You'd be better off using a kernel that has support for force fast charge. Franco's does as well as many/most others. Then you'd issue the command:

# echo 1 > /kernel/fast_charge/force_fast_charge

or 0 to disable it again. This lets the device draw up to 1A.

Shorting the data pins will NOT work since slimport hijacks them. That and there's an explicit check in msm_otg.c to force the charger type to sdp.
[Nexus 4 Accessories] karasuhebi:
I see. Thanks for the info! Is there a way to make it draw 1.2A? IIRC, the stock A/C charger outputs 1.2A.
[Nexus 4 Accessories] 4L3xN3t:
guys...I'm starting to think there's something about slimport I don't know...

stupid question...is there something else to do in order to see it working, except for connecting slimport adapter to the phone and hdmi cable to the slimport adapter??? I really didn't find nothing useful to "activete" video playing on the tv. does it works even with "desktop" or just with some apps? (to me, neither youtube works)
[Nexus 4 Accessories] karasuhebi:
It seems you're doing everything correctly. Make sure you're on a stock ROM though as I haven't seen any posts of it working on custom ROMs. It works with everything, "desktop" mode, YouTube, etc. because it mirrors your phone's display exactly. You don't need to turn it on through the phone or anything, it just works. There's no notification of it either. The only way I can tell is because the phone immediately turns to landscape view.
[Nexus 4 Accessories] 4L3xN3t:
ok, so I need to have a refund from the seller...;)

my rom is surely stock! just rooted, but I strongly suppose this is not a problem. thanks for convincing me I'm not so noob :victory:

for the future: you think it will work with CM based on the future 4.3? I really don't follow yet the custom rom's world, but I would like to "CMing" my phone very soon...Is there any desire from CM team to make it work on their next release?:D
[Nexus 4 Accessories] 4L3xN3t:
another question...at this point...someone can say which cable have I to buy? a direct link would be better cause I noticed lot of seller use the same picture which is different from the real object:good:
[Nexus 4 Accessories] lpasq:
Adding to this quest for knowledge about fast charging with SlimPort. I use the this http://www.amazon.com/Direct-Hardwi...orcycle/dp/tech-data/B007O59Z7I/ref=de_a_smtd in my car when connected to AppRadio 2 using ARLiberator app and ScreenStandby app. I run frankoKernel fast charge and my phone has two troubling types of behavior. Sometimes it fast charges normal but at some point it reverts to USB charge or not charge at all. The phone heats up terribly too and with multitasking it will cook to point of shutdown. Suggestions?
[Nexus 4 Accessories] michaelg1030:
I recommend making a mount with a hardwired small PC type fan to keep the phone cool.

Fast charge alone makes the phone run hot, so adding on the slim port and playing video/music is bound to make the phone run hotter.

Maybe you can under volt, lower CPU, or turn off cores.....not sure if any of this will actually do anything though. Your asking for the phone to put out a lot of juice and at the same time are trying to re-supply that power.
[Nexus 4 Accessories] ziddey:
If the phone gets too hot, it'll cut charging. Sounds like that's your issue. Strange I've never run into that problem, even after playing a 2hr long 720p movie while fast charging. Is your phone under direct sunlight? Like I mentioned earlier, when I had my phone on the passenger seat, it got too hot.

Otherwise, try 100mv undervolt and see if it helps
[Nexus 4 Accessories] lpasq:
With CPU UV'd by 125mv today it avoided overheat shutdown even with navigation plus music. Battery heatup did stop the charging though once temp crossed 55c. Thanks for reply.

Phone not in sun but is in center armrest console that is closed space. michaelg1030 suggestion of PC fan had me think the phone needs better ventilation. I wonder if my charger setup is also causing trouble if the 5v 1.2a is to much coming through SlimPort. I have the heat issue regardless of fast charge on or off.
[Nexus 4 Accessories] sjbr:
it is always out of stock.
[Nexus 4 Accessories] 4L3xN3t:
[UPDATE]...I've been refunded from the seller (fu**ing manhattan cable!) and bought this one from amazon...

it's still travelling somewhere in Europe...hope this will going to work...what you think?

anyway...double the price (I don't like this), but worse, 6 or 7 times the price of a WORKING chinese MHL cable...(and I don't like this too!!!) :eek:
[Nexus 4 Accessories] Smallsmx3:
Anyone here that has slimport also have the opportunity to use a miracast receiver?
[Nexus 4 Accessories] apex88:
which chinese MHL is working with the nexus 4, have you confirmed any MHL?

The slimport is now up to 71$, lol its ridiculous.
[Nexus 4 Accessories] 4L3xN3t:
nooooooooo :D

I was not saying that exists an MHL cable working with the nexus4. I was saying that the MHL standard on a phone was much more cheaper than the slimport one! another strange thing is that the cable I bought on amazon seems to be the "official" one and priced 32€...

Now, usually in Italy when something costs 71$, italian seller make "strange conversions" and magically it costs over 71€ (71$ = 55€)...why I payd it only 32€? In the afternoon I'll discover "the secret" :D
[Nexus 4 Accessories] 4L3xN3t:
THE CABLE WORKS!!! :laugh:
[Nexus 4 Accessories] zeroxia:
Heck I'm refreshing Amazon's product page every day, but there seems to be no chance to have an official price tag anymore for this adapter.
[Nexus 4 Accessories] 4L3xN3t:
where are you from? the cable I bought on Amazon came from the UK (32€) and is quite cheap in comparison with the 70$ apex88 sayd. If you're in Europe it's a good chanche:good:
[Nexus 4 Accessories] harisled:
Then it's time for you to discover this price watching site: http://www.camelcamelcamel.com/ :silly:
[Nexus 4 Accessories] karasuhebi:
Glad to hear it man. Have fun! :)
[Nexus 4 Accessories] apex88:
The slimport is available on aliexpress for 30$, it looks liek generic one and not the real one, i ordered it, update in a month :)
[Nexus 4 Accessories] zeroxia:
I can find a $29.95 "slimport" product here on aliexpress.com (never heard of this site before):

http://www.aliexpress.com/item/Free...ble-For-Google-Nexus4-1080P-3D/733390011.html

The picture depicts the adapter different from the one on Amazon. And the domain "aliexpress" reminds me of alibaba.com, a China B2B site, on which there are a lot of copycat electronics from China, and the following is the search link on its China site:

http://search.china.alibaba.com/selloffer/offer_search.htm?keywords=slimport&n=y&categoryId=

As you said "in a month", so maybe it's shipped from Shenzhen of China, and I think this probably is not the authentic slimport.
[Nexus 4 Accessories] apex88:
Aliexpress is for retail commerce, while alibaba deals mostly with wholesale.

authentic or not as long its working i'll be happy, i have no intention of paying 70$ for the original adapter, in case it will not work i'll get my money back, i already tried to order slimport from another seller but there was a problem with the shipment and i got my money back.

You can look at it as the Chinese ebay...
[Nexus 4 Accessories] zeroxia:
For your information the SlimPort is back in stock on Amazon now. Just Google "SlimPort® SP1002" and the first result will take you there. :P
[Nexus 4 Accessories] michaelg1030:
Thanks for the heads up. Just purchased one.

Now I just need to order my HDMi to A/V convertor and I should be good to go to get my Nexus4 to display on my cars head unit.
[Nexus 4 Accessories] catpunt:
looks you can also get a refurbished unit from that seller's website, I was able to get free shipping and no tax so it came out to $24.95:

http://demandport.com/index_files/Page389.htm

website seems a little sketchy but whois lookup does tie it to the same seller on amazon, so i went for it
[Nexus 4 Accessories] jimmynguyen91:
It showed up on my Amazon recommendations as I was doing some online shopping. Ordered one! $29.95 with Amazon Prime 2 day shipping :D
[Nexus 4 Accessories] ritzxda:
Just for anyone else who is interested. The one I ordered from AliExpress got cancelled. The seller "neo chow" said they had no stock and asked me to purchase something else to the same value. Seems fishy to me as the status of the order was already changed to "shipped/Goods awaiting Acceptance". I haven't got my money back yet.

On a brighter note, the SlimPort from Amazon has arrived. Unfortunately, it isn't working for me. I connected it to my TV using a HDMI cable but no image appeared on the TV. The phone however did automatically rotate to landscape. I tried with and without additional power even though that shouldn't make a difference. I also tried with my computer....just took the cable out of the PC and connected it to my phone via the SlimPort adapter but same result. Any ideas?

Thanks.
[Nexus 4 Accessories] karasuhebi:
If the Nexus 4 detected the SlimPort connection (evidenced by it going into landscape mode), I'd say it might be the HDMI cable. Try another one.
[Nexus 4 Accessories] ritzxda:
Thanks for the quick reply. I suppose there's no harm in trying another cable but just wondering...is there any reason the same cable would work with my computer but not with the Nexus 4/SlimPort connection? Just curious why there would be a difference?
[Nexus 4 Accessories] karasuhebi:
No, I don't see a reason. But it's worth a shot. :)
[Nexus 4 Accessories] ritzxda:
Haha no worries. Just quite dumbfounded (and a little frustrated) since I was so eager about my new toy :) Will purchase another cable and see how I go. Cheers.
[Nexus 4 Accessories] karasuhebi:
I'd suggest buying it from Best Buy or WalMart since you can return it if it still doesn't work for you. If you plan to keep it, I always buy my cables from MonoPrice as they are nice quality cables and super cheap. Good luck!
[Nexus 4 Accessories] ritzxda:
No go :(

Hmm, tested with a new HDMI cable. Yet again the cable works with the PC/monitor/TV but when I connect the same cable to the same monitor/TV, it just says "NO HDMI cable connection" (or similar). The TV just stays blank. The phone does however rotate into landscape mode. With the new cable on my computer monitor, the screen on the phone doesn't rotate. It rotates when I plug in a power source though. The monitor seems to pick up the connection but the screen flicks between plain black and fully scrambled black and white (no phone image mirrors across). Any chance it could be a faulty SlimPort adapter? I'm not in the US and have already spent quite a bit getting it posted across etc so don't really want to send it back before thorough testing. Is it possible that some HDMI cables and/or monitors just won't work with this?
[Nexus 4 Accessories] karasuhebi:
Sorry to hear that. I don't think there are certain HDMI cables and/or monitors that don't work with the SlimPort/myDP adapter. At least I've never heard of that. It might be a faulty adapter. :-\

What about your ROM? Are you running the stock ROM?
[Nexus 4 Accessories] ritzxda:
No worries. Thanks for your help. I will keep searching other locations where I can get one of these shipped worldwide. Interesting technology. I hope the new Nexus tablets have myDP functionality. I'm using CM10.1 RC5 at the moment. Been searching through the forums but haven't been able to find any info on myDP on CM10.1 so assume it should be working? On a side note, good to see Amazon still have the SlimPort adapters for $29.95.

Update:

https://jira.cyanogenmod.org/browse/CYAN-559

Although I'm still none the wiser based on the above. It says resolved. Hmmm...
[Nexus 4 Accessories] FeintDoxx:
I am definitely going to buy one of these before I move out into my dorm this August. I can see it now. I'll use xfinity on demand player, and all slim port to my TV, and campus WiFi to stream. Looks like I won't have problems about TV.
[Nexus 4 Accessories] karasuhebi:
Try flashing a stock ROM. I think that resolved bug is only applicable to the newest nightlies, not the RC you're running.
[Nexus 4 Accessories] ritzxda:
Thanks again. The RC5 only came out two days ago. I generally flash nightlies every second/third day depending on what changes have been made. Prior to this I had tried the nightly from the 7th of June. Downloading the latest nightly from today now. Will see how I go. Thanks for your continuous help. I hope I'm not taking this thread off-topic.
[Nexus 4 Accessories] karasuhebi:
I'd still give the stock ROM a shot. It's the only one I know that's been reported working.
[Nexus 4 Accessories] ritzxda:
Yea will do. I just tried with the latest cm10.1 nightly. Connects to TV, goes into landscape mode but TV is just plain black (flashing). Tried a video clip and an audio clip but even the audio doesn't play through the TV. Will backup and hesitantly try stock rom in the next day or two. Thanks for all your help.
[Nexus 4 Accessories] karasuhebi:
No problem. And once again, good luck. Please report back with your findings. :)
[Nexus 4 Accessories] a3551410:

excuse a question. I have the slimport, a while ago I read about an application that locks the screen when this mode slimport and you still see what was on, anyone know what her name is or where I can get it. I've seen the page 30 in the applications and nothing. I do not remember where I saw: s. was a aplciacion with many functions : Llanto:
[Nexus 4 Accessories] karasuhebi:
I don't know about locking the screen but there's certainly apps that will turn off the display while you're using your TV. The one I posted about some time ago in this thread was Screen Standby, but you need to have root:

thanks friend is quite right, sorry if I knew I explain, I am Venezuelan and my Spanish language :good:

know if my phone can be damaged, so use the slimport? by continued use of 2 to 3 hours??
[Nexus 4 Accessories] ritzxda:
Completely dumbfounded now. Same cable, same adapter, same phone, same rom (CM10.1 latest nightly). Doesn't work on home TV and monitors. However, tested at work and it works fine on one monitor but doesn't on the other.

:confused:
[Nexus 4 Accessories] zeroxia:
Any chance it's due to HDCP support? Could your TV/monitor be too old to support some new HDMI revisions? I have no idea of these stuff and it's just blunt guessing.
[Nexus 4 Accessories] karasuhebi:
I'm from Puerto Rico, my first language is Spanish as well. Feel free to PM me in Spanish if something I say doesn't make sense to you.

In short, no, your phone won't be damaged by continued use. It WILL get very hot, but the phone will protect itself from any actual damage to its internals. Turning off your screen will help though so I suggest you install that app I linked you to. Also heat makes your phone's battery life horrible for some reason so if you're not going to be charging it (which hilariously enough also makes the phone very hot) while you use your Slimport adapter, I would suggest finding a way to keep it cool like a fan or an A/V vent
[Nexus 4 Accessories] ritzxda:
Thanks for your response. I don't know much about this stuff at all but the same hdmi cables work with my computer and monitor and also computer to tv...so the tv and monitor are definitely cool with the cable. It just doesn't work with this adapter. But I know the adapter definitely works with one older monitor at work. Very bizarre. Driving me crazy :)
[Nexus 4 Accessories] stormjenkins:
I have had success on the following ROMs/Kernels:

Paranoid Android + Franco Milestone 2

XenonHD + Franco Milestone 2

The only issue I have come across is with the HDMI cable, I'm using an older one that works every time and I have tried a newer cable that didn't show anything on the TV.
[Nexus 4 Accessories] ritzxda:
Thanks for this. I haven't flashed stock rom (still using the latest CM10.1 nightly) but tried with another HDMI cable today and it worked! Still absolutely bizzare since the other two HDMI cables work perfectly fine with PC/TV. Anyway, all of the HDMI cables I have are cheap ones but for whatever reason...some didn't work with this adapter. I now have one that works flawlessly on any screen! :) Thanks so much for all your help.

I ordered from him as well, after your post i asked him if he shipped the item (he marked it as shipped), and he told me he doesnt have the item at all, I asked my money back and he asked if i want to buy something else from him, i refused and wanted my money back, afterwards he asked me if he can refund me via paypal and i'll give him 5 start feedback, i refused saying he doesnt deserve 5 stars (since he marked it as shipped even though he didnt have the item), i opened a dispute few days ago after he stopped answering my messages.

Did you get full refund?
[Nexus 4 Accessories] stevelav:
I've been using slimport with nexus 4 for a while and its pretty good really.

Can anyone tell me why I get no sound on my alba HDMI tv? I use the same TV and HDMI able with my laptop and get sound with that.

Also I've been watching Netflix a lot through the slimport while using fast charge with a Franco kernel and the phone does not loose charge or get too hot though its best to prop up the phone on its side for ventilation! I don't get HD quality video from Netflix on my phone though I think my friend with a I phone 5 gets HD from Netflix on his and he can use airplay which works really well much better than slimport or half assed miracast.
[Nexus 4 Accessories] michaelg1030:
For anyone interested. You can use the slimport with an HDMI to AV convertor to get audio and video output from your N4 on to something that doesn't have an HDMI cable.
[Nexus 4 Accessories] ritzxda:
Hey yea I eventually got a full refund but only after I gave 5 star feedback. Which is ridiculous because I have now contributed to the sellers positive feedback when it was a far from positive experience. I have made a complaint to AliExpress and asked for my feedback to be removed but haven't heard anything back so far.

My galaxy s2 MHL adapter doesn't work with the NExus 4 :( ... Maybe because of the custom rom...?
[Nexus 4 Accessories] curtisf08:
I don't know if its possible but i would love to be able to use a mod that dims or turns off the N4 display while using Slimport. I use Slimport alot and for long periods of time and use bluetooth mouse's & controllers to interact with my phone.

This surely would be more battery friendly and prolong the health & lifespan of my N4's display.

If anyone has any info on an existing mod that has this ability please let us know. I'm also keen to learn if a custom Rom or a modified Kernel would be needed to achieve this, it would be cool if only a simple app was needed.
[Nexus 4 Accessories] Cozzeck:
Yeah its in the play store, its called screen standby. It turns the screen off but still displays it via HDMI.
