It is to do with hardware, LG used Slimport instead of MHL for many reasons.

The strange thing with my Slimport HDMI is that I tested it with 2 TV's and yet I got a bit of the screen cut off and black bars.
[Nexus 4 Accessories] apex88:
I got full refund as well but without giving him 5 star feedback, and i just gave him 1 star feedback explaining everything that happened.

Got the original slimport from AMAZON working great so far, im with stock rom and stock kernel and rooted.
[Nexus 4 Accessories] karasuhebi:
Are you sure you're getting screen cut off? Just because you're getting black bars doesn't mean you're getting part of the image cut off. Remember, the resolution on the Nexus 4 does not have a 16:9 ratio like most widescreen TVs have. Something with a 16:9 ratio would be 1280x720, but the Nexus 4 is 1280x768 which is more like 16:10.

As Cozzeck said, there's Screen Standby (which requires root) and some others. Screen Standby is my preferred method and it's still being actively worked on by the developer right here on XDA. I posted the links for it just two pages back if you're interested.
[Nexus 4 Accessories] curtisf08:
I've been running it for couple of days now and its better than what i hoped for. Essential
[Nexus 4 Accessories] karasuhebi:
Glad to hear it. Mind giving me some use cases? I'd love to hear some ideas, I only use it when I use the myDP cable.
[Nexus 4 Accessories] curtisf08:
Yeah me too i only use it when I'm using the slimport cable.

PA rom fullscreen pie-mode presentations, teamviewer, xbmc, navi-x, mame4droid, ps-touch. Just being able to watch the match or race on a the big screen wherever i may be in 1080p is frickin sweet. I'm running a kernel that enables fast usb charge, not sure if it makes a difference tho
[Nexus 4 Accessories] karasuhebi:
Wow that's a lot of stuff! Thanks for the info.
[Nexus 4 Accessories] CoolApps:
One is a 1080P TV and one is a 1280x720, it completely makes sense after you said that the Nexus 4 is 1280x768.

It still cuts off the sides though due to the resolution.

I noticed that the Nexus 4 loses a lot of FPS due to it connected to the TV, I believe toys is normal since the screen recorder causes the same issue (I got around 48FPS with everything killed on the multitask screen) but the problem is that because of that it will not look has smooth has the Slimport was intended to be.
[Nexus 4 Accessories] karasuhebi:
How much of the image would you say it cuts off?

I understand that it's lagging when on TV out but I didn't understand the entirety of your last paragraph. Mind rephrasing? Thanks
[Nexus 4 Accessories] CoolApps:
Not lagging, the Slimport video will grab frames to build up a live image, wait for over 10 hours for the image, I will be out for a long time today...

Meanwhile you can look at this video, I had to change a few HDMI settings to fit it in.

https://www.youtube.com/watch?v=XZZuHfhgeZ4

It is a review but I do show the black bars which show up on the sides and some cut offs.
[Nexus 4 Accessories] karasuhebi:
I'm not sure I'm understanding your issue. Even after watching your YouTube video I'm still confused as to what exactly is happening. You said there's no lag but you said it's got a low FPS. Low FPS is lag to me. Could you record another video of a YouTube video playing on the phone? Or maybe a game? Also if you could get GMD Auto Hide Soft Keys (https://play.google.com/store/apps/details?id=com.gmd.hidesoftkeys) that will help us see where the black bar is showing up on the right hand side. I couldn't see any image cut off by the way, showing us a YouTube video or a game would help us with that. Just pause the game or video and hold up the phone screen to the monitor so we can see the difference. I think you pointed at some black bars on the left and right maybe? Couldn't really see. Hopefully the new video will help. And then as far as the part where you pointed at the top, don't know what you were pointing at. I had a hard time understanding you, the audio from the recording is not great.

Thanks again!
[Nexus 4 Accessories] CoolApps:
Unfortunately that is not possible since the Sony Tablet S Camera app crashes if you record in a certain time but I can take a picture of the areas which don't fit.

The FPS are used by the local device and screen causing missing frames so it is basically sharing frames, the highest I got in frames is 48 FPS according to a screen recorder.
[Nexus 4 Accessories] karasuhebi:
Pictures will work
[Nexus 4 Accessories] CoolApps:
Here it is, next to the scroll bar line there will be a bit of whiteness, that is where the TV frame is.

Has you can see the top, bottom and the right cannot fit well.

It took a while to take the perfect image (I used Full!Screen for hiding the softkeys).
[Nexus 4 Accessories] masterchif92:
How i can set the navbar as you Back on left and home in right with the semitrasparent circle?
[Nexus 4 Accessories] CoolApps:
I use Full!Screen.

Link: https://play.google.com/store/apps/details?id=de.tsorn.FullScreen
[Nexus 4 Accessories] karasuhebi:
I can definitely see that it's cutting off at the bottom, since the white divider lines reach the bottom of the screen, which they shouldn't. There should be some more screen there after those lines end (as you can see at the top). I'm guessing that those two buttons at the bottom are getting cut off too, but I'm not sure what they're supposed to look like so maybe I'm wrong. Besides the bottom though, I don't really see where it's getting cut off. The top looks fine, and so do the sides. Do you have a screenshot of what your phone looks like on that same screen? It'll give me something to compare it to.
[Nexus 4 Accessories] CoolApps:
I would have to do that tomorrow due to the lack of time, I'm out somewhere and because the launcher is locked on portrait unless I use the Slimport HDMI Adapter.
[Nexus 4 Accessories] Fleher:
.

nice
[Nexus 4 Accessories] CoolApps:
Back with the screeny.
[Nexus 4 Accessories] kayateia:
For what it's worth, in my experience, the SlimPort starts to lag when the device gets hot. I've seen it go with nice and fluid 60fps for a while, and then suddenly it's at 30 due to thermal limiting kicking in. So it should be possible for it to hit that. (I mean, it's not an inherent design decision or defect in SlimPort.)
[Nexus 4 Accessories] karasuhebi:
Take a screenie when Ful!screen is active so the two images (phone and TV) are comparable. :P
[Nexus 4 Accessories] CoolApps:
Oh that one.
[Nexus 4 Accessories] karasuhebi:
From what I can see, you're only losing a bit of the image on the bottom. Not bad at all. :)

Was the cropping worse before? Can you adjust margins on your TV? Is that how you got it this good?
[Nexus 4 Accessories] CoolApps:
It was.

The only thing I can do is move the image, I almost tried my best at fitting it.

I am also losing image from the left, right and the top, pretty much all sides are missing.
[Nexus 4 Accessories] karasuhebi:
Are you sure? I don't see that at all. Maybe take another picture of the TV while at a lower eyesight level? You're looking down at the TV with the current picture. Maybe that's why I'm not seeing the cutoffs.

Or maybe you're just paranoid lol jk
[Nexus 4 Accessories] CoolApps:
I already shown you a cut off but here is an other one.

My finger is on the right side of the screen which is where the black line is, the left side has the exact same thing has well.
[Nexus 4 Accessories] karasuhebi:
Ok I see what you're saying. The image itself is not being cut off though, not from what I can see. What's happening is that the TV is adding black bars on both sides to keep the correct aspect ratio. But when I pull up my Camera app, the shutter buttons ends right where yours does. Yours isn't getting cut off. :)
[Nexus 4 Accessories] CoolApps:
Yeah, that is what I mean't.
[Nexus 4 Accessories] karasuhebi:
Yeah sorry about that. Huge misunderstanding lol

So anyway, can't you manipulate the margins to make it stretch more to the left and right? Keyword here is "stretch", since that's what you'll be doing to the image if you want it to fill the entirety of your screen because as I said earlier, the aspect ratio on your TV is 16:9, while the Nexus 4's is not.
[Nexus 4 Accessories] CoolApps:
I cannot do that on my TV but my lounge 3D Cinema HD LG HD has such feature but I really can't be bothered doing that since the HDMI port I was using is the XBOX 360's.

5.1 multi Chanel via slimport????

Have read 31 pages of this thread, BUT!!!!!

Does this out put true 5.1 multichannel out of the slim port?

Analgesics website specs state:

Digital Video and Audio Output=

SlimPort output over mini or micro-USB connector

DisplayPort, eDP, or MyDP output over any connector

Configurable 1-lane output supports: 5.4Gbps, 2.7Gbps or 1.62Gbps data rates

Stereo (3D) video output support

Single Wire (C-WIRE) sideband communication

Integrated CEC Support

HDCP 1.3 content protection (optional)

HDMI Receiver Input:

HDMI 1.4a compliant

Supports max pixel clock rates up to 185Mpixels/sec

Up to 30 bits per pixel color depth support

Up to 8 Channels audio support

Android jelly bean, 4.1 android version supports multichannel audio on devices that have hardware multichannel audio out through the HDMI port.

So with all that? Can it output 5.1 multichannel via hdmi.

Have tried, no success using ALL andriod media players.

Have also tried acer a700 tablet dolby licenced, kindle fire hd, archos Internet 5(works on spdif coax) and many other android tablets!!!

Any ideas?
[Nexus 4 Accessories] xtrojans:
Also if any one can truly help

With this or info on a mobile touch screen device ill give them a slim port cable.

If you can help with finding a working device, I give you a new nexus 4 with a slim port hdmi cable.

I have 2.

Any help to find a working solution would be great and will be rewarded.
[Nexus 4 Accessories] wolfboy1984:
If it did - I'm sure they would be advertising the fact that it's possible (in its simplest form). Wouldn't you need an optical cable and additional hardware (at the very least) for multi channel sound?

I'm haven't been totally enamoured by Analogix's claims and support since its release...

[Nexus 4 Accessories] xtrojans:
Thanks for pointer.

I'd read the link before, It's the audio out put i need, basically 6 chanels out to my av amp from a touch screen device.

all these players seem to take an ac3 and down mix to stereo pcm regardless of what i do.

acer a700 is dolby branded and licenced.

nokia n8 and kindle fire hd also.

none seem to just pass the audio directly through and out the hdmi to av amp for the amp to decode and play 6 seperate chanels.

stereo pcm is all i can ever seem to get.

jelly bean says it can do it, slim port seems to say it can do it, xbmc media player can do it(and most other things aswell).

And the silly little rasbery pi can do this without a glitch, even though its 1/4 as powerful as and thing I'm testing mobile device wise???????

So a mhl adapter that has power will work ?

Jw cause slim ports ain't cheap . but mhl can be had for as little as $5
[Nexus 4 Accessories] xtrojans:
Don't need to power with slim port, very neat and tidy.

There not massive amount of money if you think on how handy it is and to the cost against the cost of your phone.

£230 nexus 4

£25 slim port, not far of iphone lightning av adapter???

Also didnt think mHL worked on nexus 4

Slimports the way forward and should be the standard unless something better comes along.

1080p 60hz + no charger needed

If more phones come with it as standard then the price will start to drop. I bought a secondhand one for £19 pounds off Amazon. Best phone accessory I've ever bought and when the new double port version comes out (vga+hdmi) i'll sell mines and get a new one

This is awesome. Combined my slim port with my PS3 remote (and six axis app) and it rocks.

Also, have a setup in my car so that my phone displays on my head unit using slim port and HDMI to VGA convertor.

Thinking about modifying a BT control so I can have an analog stick in my car to navigate the android on my head unit. Kind of like how it works in Mercedes.

Slimport HDMI to Mini HDMI Projector Connection?

Read through 33 pages of this thread and saw some people facing similar problems - anyone solved this issue? - Connecting a rooted Nexus 4 (No ROM changes) to slimport to HDMI and then HDMI to mini HDMI into a picoprojector does not work. However the HDMI into a monitor works perfectly. Also tried to convert HDMI to RCA and into the projector which did not work but RCA into monitor worked. Can anyone figure out what the problem is? The HDMI to mini HDMI works with other things and have already tried two different picoprojectors which did not work.
[Nexus 4 Accessories] michaelg1030:
Did you use a converter or to do HDMI to rca? I can confirm that from phone to slim port to HDMI cable to converter (HDMI to a/v) to rca cables to TV works.

Hi guys!

I'm going to do a question I know has been made lot of times in this thread (just don't know where anymore)...but I think we could even do a sort of list and place it in the first post.

Which roms, except the stock one, are compatible with slimport cable? I heard lot of times "doesn't work with this rom...blabla blabla" so one of the reasons I doesn't flash other roms is cause the slimport...

any ideas?:fingers-crossed:

what about 4.2.2 custom roms??? CM and AOSP have slimport support?
[Nexus 4 Accessories] salem_christ:
Is there an app or something to turn the touchscreen on the phone into a trackpad/mouse for when the android UI is displayed on a monitor using the slimport adapter? I have a bluetooth keyboard, but not a bluetooth mouse, and was hoping I could just repurpose the nexus 4's screen as a trackpad when "docked". It'd make a neat little mini-PC that way.

I've found apps to turn the phone into a wifi trackpad for a computer running trackpad server software. But I want it to be a trackpad for itself.
[Nexus 4 Accessories] 4L3xN3t:
don't know if exists...but I think is unuseful with slimport...slimport replicates the phone screen on an external monitor...if you touch the screen you interact with the desktop...:laugh:
[Nexus 4 Accessories] curtisf08:
There's an app called "screen standby" that can automatically turn your screen off once it detects a Slimport connection and also let's you use your screen as a touchpad or a full remote on a second device

Hey guys, I recently got a Slimport adapter from ebay for $18 and I got a couple cheap HDMI cables from ebay too. When I plug it in my N4 running 4.4 nothing happens. Is there anything I have to do to get it to start working? Would the cheap HDMI cables prevent it from working?
[Nexus 4 Accessories] ezio84:
Connect the hdmi cable to your tv, then connect it to the phone, and connect the charge cable only after the screen is mirrored on the tv.

If i connect the charge before the mirroring, nothing happens.
[Nexus 4 Accessories] r00t4rd3d:
I get no screen mirroring no matter what order I plug stuff in.
[Nexus 4 Accessories] ezio84:
Strange... you should try on another tv or with another hdmi cable...
[Nexus 4 Accessories] hazopoulis:
Did you have any issues with this cable after all? I tried the one with the red logos from ebay with a lot of different set-ups but it didn't work. The analogix seems still expensive to me.
[Nexus 4 Accessories] karasuhebi:
I believe it's not a good idea to get the eBay myDP cables just yet. I think that's the problem. HDMI cables have been around for forever and a day so the eBay ones probably work just fine (I'd still test them with some other device, maybe a BluRay player or a Xbox 360) but those myDP cables are pretty new so they probably still have issues.

Besides the $30 Analogix cable, Amazon is selling a Cable Matters cable for $20. I'd give that one a shot.

You shouldn't need to connect the microUSB cable to supply charge. That was only the case for older MHL cables. MyDP cables are able to work without a USB power source, at least the ones I have.
[Nexus 4 Accessories] hazopoulis:
Thanks for the info, I didn't notice the one from Cable Matters before. So does it work? Has anyone tried it?
[Nexus 4 Accessories] karasuhebi:
I haven't tried that specific cable but I've bought Cable Matters cables before and they work fine. Plus it has 4 stars out of 5 based on 25 reviews so more than likely it works. If anything, Amazon will let you return it so you should be fine.
[Nexus 4 Accessories] ezio84:
Yes, it can work without a power source, but it's a feature provided by the slim port standard.
