Some folks have gotten burned by cheap chinese junk in the past. That doesn't make them stupid to be gun-shy of that.

That being said, generally you are correct. Why pay 1000 bucks for a diamond coated HDMI cable from best buy when you can buy one from amazon for 4 bucks.
[Nexus 7 (2013) Accessories] sensboston:
Agree, "stupid" isn't correct word; "naive" fits more :) BTW, if you are here (on XDA) you should have some technical knowledge "how things works" or you may ask...

Also, some folks have gotten burned without "cheap chinese junk" - there are lot of idio... oh, no!.. naive people around the world. But if you get burned with $30+ adaptor with the "brand name" onboard, nobody will compensate your loses...
[Nexus 7 (2013) Accessories] LauraSakura:
I just wanted to get the official one, because of fast free shipping, and the fact that I've been burned in the past due to cheap Chinese versions of things.

And no, I don't buy monster cables. I do buy the cheaper versions from the store. I'm mostly just hesitant when ordering online. (Like the nexus 7 keyboard I bought that took more than a month to arrive)

That's not quite true.. if you contact customer service you can often get a replacement. Amazon is , in general, great with returns. Also, please don't be so condescending. Many others in this thread have posted about the same exact adaptor I got, yet you single me out. The fact that I sometimes spend more money on better equipment or to get things faster doesn't mean I don't understand technology. To put it bluntly, there's no need to act like a high and mighty jerk.

Can you guys check if the charging function of SlimPort can keep up with some heavy usage, like HD video streaming or game playing? But of course you should use the wall warp to provide enough juicy to the tablet.

I think there are somethings the SlimPort can improve, like turning off the tablet screen while outputting to external display, or even make it dual display.

I doubt he even has the Nexus 7 at all.

I'm in China and I can't find such $3 SlimPort rip-off product on taobao.com, it's somewhat priced at $20 equivalently:

[Nexus 7 (2013) Accessories] kmartburrito:
Some bad news. Initial observations from last night I streamed a movie through plex at 1080p, and the slimport with attached OEM charger and cable I was very slowly losing battery. I want to do more testing, but it seemed like the slimport either took some of the current for itself or the Nexus7 was using a tremendous amount of it. I will do a test later tonight that can measure the current throughput to ensure that it's charging at full current.

I did find, however, that with the slimport attached (without microusb charger plugged into it), you CAN wirelessly charge, but I found it to not keep up with the demands of plex and the attached slimport, just like the standard charger. Note when I was doing this test I only had one charging method active at a time, either wireless or through the slimport charging port.

I will do more tests, but it looks like in general there might not be a way to perpetually output to hdmi through slimport, as I'm not finding a charging method that can keep up with all scenarios, mine using plex as an example streaming 1080p

Oh yeah, and also, the back of the nexus was pretty toasty.
[Nexus 7 (2013) Accessories] IamPro:
Can you try another charger like Samsung for Note 2/S4? Wireless prob not gonna work :(
[Nexus 7 (2013) Accessories] kmartburrito:
Not sure what you mean for another charger. Do you mean another charger through the slimport? If so, I CAN do that, I have a 2.1A charger for my touchpad that will work.

I do want to clarify that I used the stock 1.35A charger through the slimport and through my wireless charger.

Wireless charging DID work, although in neither case was there a net gain in battery while using the slimport.

What I did find that is interesting, however, is that when I use the stock charger with no slimport, I'm getting ~1.1A of charging current. When I stick in the slimport, it goes down to approx 500mA. That's why this thing isn't charging fully!

When using wireless charging, I'm staying around 1A, which is promising.

So, rule of thumb, until someone can hack the kernel possibly to allow higher amperage, If you're going to use the slimport, use wireless charging!!!
[Nexus 7 (2013) Accessories] IamPro:
Yea I meant the 2.1A :)

Sad to hear that the Slimport limits the charging rate when plugged in. I was thinking wireless wasn't going to be optimal but with this news changes everything.
[Nexus 7 (2013) Accessories] kmartburrito:
My 2.1A charger also is limited to ~500mA :(

I'm going to test here in a bit with it going through my living room TV again to see if at 1A if the power is draining/charging/staying the same.

On my desk with the slimport plugged in and NOT actually having HDMI plugged into it, I'm slowly charging(maybe +1% every 20-30 mins?) so will be curious to see if it is the same when HDMI is actually plugged in.

I'll report back, for science! :D

Before I send it back....I got the Analogix Slimport adapter, but when I hook up to my TV I'm not getting a picture. Since the N7 2013 is a 1080p screen will a 720p screen refuse to show? I don't have a 1080p screen to test with currently, but plan on getting one at some point.

Went ahead and got the Kanex

I went ahead and ordered this from Kanex directly, free shipping.

I was thinking maybe one day I will get a monitor with HDMI input, bluetooth keyboard and mouse and make a pseudo pc using this slimport. But really it is because it will be more useful for my Nexus 4 and Nexus 7 in hotel rooms during travel, not sure Chromecast will be hotel room wifi friendly like you said.
[Nexus 7 (2013) Accessories] macaumen:
Just did some testing with real racing 3. If I only watch my TV without watching the nexus 7 while playing, I can never win a round. The latency is not bad, but bad enough for fast response games. Hope that helps.
[Nexus 7 (2013) Accessories] sfhub:
I wonder if the latency is due to the HDCP encryption
[Nexus 7 (2013) Accessories] Obveron:
HDCP should only be active for DRM videos that invoke a handshake with the display.

I have a question - How is the the second display handled in Android? Is it a second workspace similiar to "extended desktop" in Windows?

Or is it just a direct mirror of the Android workspace on the tablet?

If it's a mirror, then wouldn't there be some scaling happening? The tablets workspace is 1920x1200, but if slimport outputs 1080p, then there must be some vertical squeezing of the image (or cropping). Can someone tell me how it works?
[Nexus 7 (2013) Accessories] sfhub:
I understand how HDCP is "supposed" to work, but according to reviews on the Nexus 4, analogix slimport is sending out HDCP all the time even for non-DRM video

Perhaps you could verify if that still is the case with Nexus 7.
[Nexus 7 (2013) Accessories] kmartburrito:
Will be curious to see if the Kanex slimport also has the 500mA charging limitation. I bet it's due to some specification, and will be present on all slimports. Curious though, let us know what you find out with regards to how it feels to charge while you're using it.
[Nexus 7 (2013) Accessories] DaPhang:
Kanex Disclaimer on Charging

Hmm...in the disclaimer of the product sheet, it says you have to have a "SlimPort compatible" HDTV. So your TV needs to support the slimport in order for you to get proper charging. Anyone know anything about this?

http://www.kanexlive.com/files/Slimport_Salesheet.pdf

I will report back once I get it. Still hasn't shipped yet so who knows when I will get it to test.
[Nexus 7 (2013) Accessories] kmartburrito:
I missed that when I looked at that datasheet earlier, good catch. Not sure what it means. I did find this slimport whitepaper though, and saw this within it which was curious (and vague)

http://www.analogix.com/pdf/slimport_paper.pdf

Taken from the table -

Mobile Device Battery Charge - supported - SlimPort products minimize battery drain and, in some cases, charge the device.

It seems that slimport is able to mirror the device without external power, like MHL requires external power(IIRC). That would mean that any charging, if that premise is true, is a net gain to the device, as the dongle is not consuming any of it. Saving grace in all of this is that wireless charging works while using the slimport, so to me that helps.

Since I measure a limit of 500mA using that "optional" microusb port, my only thought is that the manufacturer of that cable either didn't give much thought to it and made an oversight, or there's some other sort of reasoning why that much current couldn't pass through the microusb port simultaneously with the signal coming out.
[Nexus 7 (2013) Accessories] DaPhang:
I could be way off here, but besides them choosing to use wires that are not rated for higher current, it might be because of FCC compliance. Maybe they couldn't keep the EMI interference to acceptable levels while transferring >1Amp along with high speed data transfer. Could also be that through testing, they found performance not being acceptable while transferring 1080p signals and at the same time charging your device.

Even another speculation could be that the device is just not designed to accept high current while using resources to transfer data out. The current limit you are seeing could be dictated by the device itself.

I think they are just working with trade offs in their designs and we just have to live with it. I think I am just not going to expect it to charge by N4 and/or N7 while using the slimport, just expect it to not drain my battery considerably while being plugged in.

Just for reference, I have noticed that on the official wireless charging orb for the N4, while I am using it, charging tends to be very slow and sometimes even loose charge, but once I put it to standby, it charges as normal. So I agree about your statement of net gain. Hopefully it will be a gain, if not, hopefully it won't be so bad. <fingers crossed>

Here's an idea, have you tried just plugging everything in except the HDMI to the TV? What is the current when you do that? I'm just curious if you are not mirroring, what the charge currents are.
[Nexus 7 (2013) Accessories] Obveron:
I'd love for anyone with a slimport adapter to share some info on how multi-displays are handled by Android in respect to scaling the native 1920x1200 image to 1920x1080.

Is it difficult to have the correct aspect ratio displayed on the TV for videos and pictures? My expectation is that if Android and apps are configured to display natively on the 16:10 tablet display and that Slimport mirrors and scales it for 16:9, things will appear vertically squeezed on a 1080p TV.

Is there a way to configure the Android workspace for 16:9 1080p so that movies and pictures are pixel perfect on the TV, making it vertically stretched on the tablet (but that's ok)??
[Nexus 7 (2013) Accessories] rsfinsrq:
Just received my Kanex Slimport adapter. My first observation is that it rattles as if something is loose inside. I connected it using the OEM charger cable and Belkin high performance HDMI cable to my Sony KDL-52W5100 HD TV and no go. It does not seem to work. My other devices (Note 2 using All Share Cast, Note 1 using MHL Adapter, Dell Streak 5&7 using OEM Dock) all work with the TV. I'm not sure if my TV is not Slimport compatible, if I have a defective unit (Don't think it's supposed to rattle), or there is a settings issue on my tablet or TV. I have emailed Kanex Support requesting an exchange hoping I just received a dud, but in the meantime I will continue playing with the settings. If anyone has any suggestions it would be appreciated.

The new Nexus 7 isn't in the UK at the moment, but I'm curious to know about the quality of movie play back via the slim port.

Can we turn nexus screen off whilst still streaming to tv?
[Nexus 7 (2013) Accessories] MrWulf:
I'd be curious to whether the output is vertically squashed or whether there are black bars on top and bottom of the output and the aspect ratio is kept consistent as well.

I am also curious whether the charging port on the slimport adapter can be used for USB in so I can connect my 360 wired controller while using the tv out. Now I think about it I have even more questions. Can a hdmi>DVI cable be used? And if it can, can the device use bluetooth or analog audio output while outputting video via the slimport?

I ordered one of the MyDp units from ebay awhile ago, so it should be along this week or next. I'll check these questions out if no one has by the time I receive it and report back if anyone else is interested.
[Nexus 7 (2013) Accessories] monouchi:
I bought the Analogix adapter, and the full Nexus 16:10 display is evenly scaled down to fit within the 16:9 ratio of the tv. This means that the image you see has the correct aspect ratio, but is pillar-boxed on the tv screen. This also means that it's not a 1:1 pixel mapping. In fact, playing back a 1080p 16:9 movie appears both letter-boxed (to fit in the 16:10 Nexus ratio) and pillar-boxed (to fit back into the 16:9 tv ratio) when played back on the tv. The scaling quality is good, but I'd much prefer 1:1.

My Asus 10" tablet handles this much better. When it detects an hdmi connection, it letter-boxes the tablet display and forces Android into an aspect-correct 16:9 mode so that it can mirror the display to the tv. I was really hoping the Nexus would do the same thing, or at least give me an option to reconfigure this, but I haven't found any settings for it. Overall I'm a bit disappointed, this seems like a step backwards.
[Nexus 7 (2013) Accessories] Obveron:
Thanks for the details monouchi. That's most dissapointing. I wonder if Google would ever patch Android to give more display options. The way your Asus tablet works makes the most sense.

Just ordered the one from dx, I'll post a quick review once I get it. I'm sure it has the same problem of the others when it comes to resolution & scaling.
[Nexus 7 (2013) Accessories] MrWulf:
Thanks for the info monouchi!

I actually prefer it retain the same aspect ratio so as not to cut pixels off the top or bottom or squash it down personally, so that suits me well.
[Nexus 7 (2013) Accessories] Obveron:
It retains the aspect ratio but is forced to destroy the pixel clarity by a drastic downscale. Basically the current Nexus 7 2013 implementation is to downscale the 1920x1200 to 1728x1080. This avoids cropping and squashing but it's a terrible un-even downscale that means there will be nearest-neighbor pixel rounding on both the vertical and horizontal.

The way monouchi described how his Asus tablet works is much better. The Android workspace is changed to 1080p 16:9. Nothing is cut off or squashed. Android is re-rendered in 1080p. The tablet displays 1080p with black bars at the top and bottom (only when connected to the TV). The TV output will be a pixel perfect mirror of that 16:9 workspace, with no need for black bars.

This option is better because the black bars are on the tablet while connected to the TV. It's also much better because 1080p movies and pictures will be viewed on the TV with no scaling.
[Nexus 7 (2013) Accessories] jimpmc:
There is a thread in the Nexus 10 forums about how to switch the native resolution to make it work without scaling. The solution requires you to be rooted. Someone posted info about the Nexus 7 2nd Gen, which is:

I have Nexus 7 2nd gen. Native resolution is 1200x1920 and default density is 320 (though technically the density is about 323).

To get it to work correctly in 1080p, I have to run the following commands as root:
wm size 1080x1920
wm density 288

To change it back:
wm size reset
wm density reset

If I don't change the density to 288 or smaller, the icons and everything get messed up, especially in landscape.

[Nexus 7 (2013) Accessories] mikeneron:
I tried both the official Samsung MHL adapter as well as another one from Monoprice (Product ID 10020) with my Samsung Galaxy S3 and it always had a slight lag which made playing games that involved you to react pretty much impossible. So am not going to fork out another $30 for a slimport adapter for the Nexus 7 unless I know there is zero lag which is kind of sounds from one other post that's not the case.

The test I used was using a NES emulator (Nesoid) with Mike Tyson's Punchout. Get past Glass Joe to Von Kaiser and he kind of winks at you before he is about to jab. If I am looking at my S3 screen, I can dodge in plenty of time. However, if I'm watching my TV screen there is enough of a delay that you get hit. Also works perfect with the 2013 Nexus 7, but was hoping someone with a slimport adapter could do this test with the Nexus 7 hooked up to a TV and let everyone know the results.
[Nexus 7 (2013) Accessories] flar2:
I just received my slimport from amazon.ca and it works fine.

This is the one: http://www.amazon.ca/SlimPort®-SP10...=UTF8&qid=1376666860&sr=8-1&keywords=slimport

My observations:

-it doesn't require external power (it is powered by my TV, some may not provide power), but this doesn't charge it

-plugging a usb cable into the slimport adapter does charge it

-OTG adapter does not work plugged into the slimport adapter. The slimport adapter trips the ID pin on the usb port, and shuts off the 5v output to avoid current leak. I didn't try with otg adapter + y-cable connect to power source. I will experiment more.

-the hdmi output is 1920x1080 at 60Hz (on my TV, depends on your TV's capabilities) so there is no lag, very smooth (note that many devices limit to 24Hz or 30Hz at 1080p and it looks choppy)

-unfortunately the output is pillarboxed by default. This can be fixed by doing (as root)

wm size 1080x1920

wm density 288

then reset with:

wm size reset

wm density reset

I don't think this is something to be fixed in kernel, the kernel is doing what it's supposed to with respect to output resolution to lcd and hdmi.

Someone should write a daemon or system service that detects hdmi status and runs these commands automatically.
