Assuming the USB input for the touchscreen works with the Athena, this could be a nice in-car dash accessory. It would make GPS/map use really sweet, and phone dialing easier. $195.
Anyone want to test it?

that would be pretty cool
I keep talking myself out of buying it. At $195 its almost cheap enough to get even if the touchscreen part didn't work with the Athena... but then I would talk myself into getting a mini-PC, and at that point I could have just bought a cheap laptop.

as long as the usb output act's like a standard pc mouse it works. and thats where the problem starts the manual (see the grey box at right side at the bottom) says somthing from 'install the usb drivers first!' so i think there is no luck with these thing. elsewhise a cool idea as an addon in the car.
greet's mad
I figured it would come down to a driver issue for the touchscreen. Still an off-chance it might work out-of-the-box, or that the company offers a WM driver.
for me, i think that would be a bit expensive, i bought a car headrest monitor at Eonon.com, which just need $175USD!
Has anyone found a compatible bluetooth mouse? I can't find a standalone bluetooth mouse that will successfully pair with my DB (I have tried a Targus Model#: AMB04US and a Think Outside BT Mouse).
Furthermore, all posts I can find relating to the subject are for a keyboard with a built-in trackpad but I hate trackpads. I want to use a standalone bluetooth mouse and don't want to have to buy a dock (I am using the Webtop hack that bypasses the need for a dock).
Thanks in advance.
I successfully used my MS Bluetooth Mouse 5000 on the web-top. But here's the thing that might be causing your issue with the other mice: When I went to pair the mouse with the web-top it was waiting for me to enter a pairing code on the phone screen window and since i had that window behind a Firefox window and I didn't realize it the pairing process kept failing.
Logitech has a mouse out meant for android tablets. Maybe give that one a try?

Thanks for the suggestion. I get the pairing code window, but when I enter 0000, 1234, or 4321 (per Motorola Support's suggestion), they all fail. Targus support says it is because there is no PIN required. So if I enter something then delete the pin I entered (just to get the OK button to activate), it still fails.
I'm glad to hear that the MS Bluetooth Mouse 5000 works though. It appears reasonably priced online. Motorola wants me to go buy their mouse for $40+shipping. Seems a bit steep for something that clearly isn't working due to software incompatibility.
XDA Community: Please post other mice that have worked?
I wanted to close out this topic by giving others the following insight:
The MS Bluetooth 5000 mouse works flawlessly with my Droid Bionic both in standalone mode (nothing attached) and in Webtop mode (with the WebtopMod_Hack that enables you to get to webtop without a dock). I purchased it for $18 from a seller on eBay and found other sellers listing it for $20-$25.
Hope this helps future purchasers out.
Same here...
I'd also like to chime in and say the Microsoft Bluetooth Mouse 5000 works just fine.
It really irks me though, because I have an older (ironically) Bluetooth Mouse 8000 which I really liked because it had an integrated laser pointer and presentation controls on the underside of it. I could never get it to pair.
Microsoft must have made some changes in the device firmware stack because now with the 5000, I could get it to pair to my Bionic using the passkey 0000.
No matter what I tried, the 8000 would not pair.

I have the wireless Apple Mighty Mouse that I use with my Mac and that paired up well with the phone.
I'm running the latest CM9 SELFKANG. The cursor works fine. Scrolling with the trackball is great. Clicking is fine. But it lags and locks up horribly on stock. Anyone else notice that?
Mouse Acceleration?
Do you have any mouse acceleration with the mice you have tried? I just tried to plug in a Logitech MX518 to the USB-port and i have terrible mouse acceleration (when you move the mouse slowly the mouse sensitivity is really low, but when you move the mouse fast the sensitivity is much higher).
I need to find a mouse that does not do this (or a program that will correct it).
I found a solution to this maddening issue!!!
Solution is very simple!
1) Download an app called bluetooth pairing in Play Store, its in japanese but all you need to do is click the magnifying glass icon, then click your device and hit the big blue button that comes next..
2) Disable and enable your bluetooth on the phone, the device is already paired
3) Select the device and it works perfectly.
Discovered this fix accidentally..
I use the Microsoft Bluetooth Notebook Mouse 5000. Works awesome no need for a third party program the mouse cursor works fine and you can find tune the mouse cursor in the language and input settings of the settings menu. I really like using the scroll wheel and you can even use right click with in ES File Explorer.
I use this same mouse with my laptop.

Anyone tried a Razer Orochi mouse? That is the bluetooth mouse I want to pick up for my laptop since I hate dongles and am adding a bluetooth transmitter internally to the laptop. Would be nice to have a mouse that will work for both my laptop and for my DB with the lapdock. I know that with the lapdock most USB dongle wireless mice will work but I hate dongles and I know one day I'm going to lose the stupid thing and be SOL.
I'm considering purchasing the HD Dock, mainly for the remote as well as the docking features as well. But my question is, is the remote only able to be used when in the dock, or can I use it whenever? Also, is it bluetooth or infrared?
Thanks guys!

You must be docked to use the remote. I believe it's infrared.
Honestly, the remote is a nice bonus, but if it's really your main reason for buying the HD dock you will likely be disappointed. For one thing, it doesn't work with all apps -- the Netflix app, for instance, won't respond to it. It will work with Google Music, some video players, and you can use it to scroll inside a web browser. The volume/mute buttons can be useful. The buttons however can be kind of "sticky" and difficult to keep from over-pressing.
Having said that, I love my HD dock. I hardly use the remote though. I have a wireless mouse and keyboard attached via a USB dongle and I mainly use those to navigate, in both Webtop and Mirroring modes. I think you will find a wireless mouse works much better for most couch-surfing purposes vs. the remote. Logitech now makes a "couch mouse" which works great for me.
It's a special RF remote. It works directly with the dock. It is rather short range too, likely because it uses a button cell battery. On the plus side, the dock enables USB host, allowing for use of flash drives, keyboards and mice.
I got mine for $55 on ebay. Keep in mind that it doesn't come with the hdmi cable(I know), but you can get one from amazon for like $5.
[Edit] It looks like I was wrong. It is IR. Just checked it with my camera app. Most camera sensors detect IR and translate it into white light.

I bought a HDMI to VGA converter to be used with my Nexus 10 with projectors to give presentations. Now I connected it to my desktop monitor (via VGA), and it says "reduce resolution".
Is there a way to change the resolution? Or is this something the converter should actually do? (which I can't do, it just looks like a cable).
Thanks!
Which adapter do you have? I've been looking for one for a while.
As far as I know the HDMI out mirrors the native screen resolution. It's been that way on every android device I've used.

The n10 outputs at 1080p...always. You can't turn it down or up. You can't just switch the pinout of HDMI to VGA. It can't be done. You have to convert the signal from digital to analog. That is sometimes done inside the vga sink (many data projectors), but it is more often done with an external converter.
As for bringing down the resolution, you need to first input to a scaler that has granular resolution control an scale it down.
What about video projector?
Does that mean we can't hook up the N10 to a VGA video projector via an hdmi-to-vga converter? All the VGA video projectors I have at work have very limited resolutions (800x600, 1024x768, 640x400).
I'm really looking forwarding to get an N10 for presentations so this would be show-stopper. Your help and suggestions are most appreciated!
Getting a little frustrated with this. On my Motorola Xoom (original WiFi), I had a solution that worked. It was kind of sloppy, but it did work. I had a micro-HDMI to HDMI adapter, a small power injector (HDMI Female on one side, Male on the other), and a HDMI to VGA adapter. All those connected together accomplished the task of connecting the tablet to VGA. (the power injector was needed because the micro HDMI port didn't put out enough power to push the video).
That same setup doesn't work on the Nexus 10. I tried removing the power injector and that didn't work either. In both cases, the monitor accepts a resolution setting from the tablet, but I just get horizontal gray bars as far as the image itself. I just got in the mail a Samsung micro-HDMI to VGA adapter that is supposed to be for several of their laptops AND slates, but that didn't work either. This time, again it accepted a resolution setting, but I get a complete gray picture (no bars, just big gray box).
I'm really getting disappointed that there isn't an easy solution to this. There are way too many businesses that still only have VGA connections and since I use my tablet as a laptop replacement/for presentations/etc, it's a must have.

I think that's the problem of the N10 hardware, I tried to connect my N10 to a HDMI TV, I get the same gray picture as you described.
Called Google support and they are sending me a replacement. Also I have severe light bleed on the lower left and rigt of the screen as well.
A little disppointed.
I purchased this connector http://www.amazon.com/gp/product/B00879EZJI/ref=oh_details_o03_s00_i00 and it worked perfectly. Was able to hookup my N10 to a VGA monitor. Monitor did not have 1920x1080 resolution and it still worked.
Sounds good. What resolution is the monitor showing?

This worked!!!! Thank you lorloff for posting this. For anyone who cares the resolution scaled down to 1280 x 720. I tested on a standard computer monitor and a TV that my office uses with presentations/meeting. I am not sure why, but the TV didn't display across the entire screen (had side black bars), but it is good enough. The computer monitor took up almost the entire display, but that could have been that the native resolution was lower than the TV. Anyway, point is, this solution definitely works.
Similar issue...
Hi guys. I have a similar issue, but my nexus 10 crashes when connected to the projector. I can see the image, it works for about 10 seconds before dropping it, reconnecting, then crashes completely and restarts. I am using the same HDMI - VGA cable as mentioned on here. I thought it was the cable, and they replaced it for me, but it hasn't helped. Has anyone else experienced this? Any thoughts on if this is Android or the hardware causing the issue? Any help would be much appreciated as I really need to get it working or is it a case to send it back to Google? The projector is a viewsonic pjd5122 by the way, which has not given any issues before. Cheers for your help/thoughts.

Hi all, I also bought the Cable Matters Active Micro HDMI to VGA Adapter as suggested by lorloff, but it does not seem to work with my Nexus 10. It's on KitKat 4.4.2.
When I plug it in, the tablet becomes slightly less responsive and the device (projector/monitor) I plug it into only gets a black screen, it's not blank, just an off black. It seems that the signal is going through and at 1920*1080 resolution, but not picture is showing. I purchased two of these adapters and both do the same. The adapters work because I have tried it with a phone and I get a mirrored image instantly, at 720p. I've tried it on 3 different types of monitors, 17 and 24 inch, and 3 different types of projectors, one of which can do resolutions beyond 1080p.
The HDMI out on the Nexus 10 works, as when I connect a micro HDMI to HDMI adapter directly into a projector I get instant mirrored output, but at 720p. I've also tried with and without additional power through the adapter and having the tablet plug in charging, but nothing helps.
I'm thinking of getting the KanaaN Micro HDMI to VGA Adapter as that seems to work for others, but then again so did this adapter... Any ideas?
Same for me with a generic HDMI to VGA.
I'm running 4.4.2 as well on my N10.
So should it be an OS issue ?

There is only way to change the resolution. You must get another hdmi to vga converter from Hdgenius . Maybe there is something wrong your device in quality.

Any new leads? I have got the same problem using the cable matters adapter.
From the looks of it passive adapters don't properly work as it relies on the N10 being able to convert the digital HDMI signals to the analogue VGA. The Cable Matters one that was linked above is an active one and does the converting instead, which allows it to push for a higher resolution.
I already have the Cable Matters adapter, it doesn't seem to work, though. I get a black screen even after connecting the USB power chord. Any ideas?
Hey everyone. I just bought the Samsung Smart dock. Everything seems fine, but there is one Problem.

I'm pretty sure if you click on the bottom where the controls are supposed to be they will show up.
That's how I got mine to show up.

Now i can guess why this isn't working so well. Im using a Wireless Keyboard+Mouse combination through a stick ( not bluetooth). The Phone doesn't show the Keyboard in the drop down menü at all, but the Keyboard works though. This must be the Reason.
Does anyone know a trick, where i could make my phone think, that a usb keyboard is plugged?
EDIT: Found a trick. I just plugged in an another USB Mouse and the display of the Phone turned off. Now everything works great. Its a waste of a USB slot, but im ok with that...better than buying new Wireless Keyboard and Mouse.
EDIT: Its laggy somehow, if 2 Mouses are connected. I need a way, to modify the USB reciver of the Mouse/Keyboard. Anyone can tell me, how to get access to a USB devices, to modify it?

The lag might be because of the screen turning off. I currently have that issue. When I plug in a wired mouse, the screen on the phone turns off but the output over HDMI gets really laggy. It happens even when you only have the wired mouse connected without any other USB peripherals. I haven't found a workaround for it yet.
The case is... hardware video overlay.
To be more specific:
1) whenever a hw-decoded video is played, it is handled by GPU only (-> only video surface is rendered, no software overlay controls, etc. available via HDMI)
2) you can force software rendering ("composition") by attaching an external USB HID device (mouse/keyboard, but keep in mind that a USB RF receiver for mouse/keyboard does not trigger renderer switch) - both video and overlay controls will be available via HDMI but with a degraded performance ("software rendering")
I do the following: use external mouse, etc. to select a desired video, click 'play' and then disconnect the USB accessory.
Tell me about the smart dock, it looks like it should be charging a spare battery in the back but I didn't read that anywhere in the description... Also you can only use it in portrait mode?? What's up with that? I find it hard to get over these 2 hurdles for $99.

The back of the device has hdmi out, micro usb port for power and 3.5mm jack for audio out to externally powered speakers. Initially it will only work in portrait but you can either use a launcher or you can use the app Ultimate Rotation Control to force the phone into landscape, even on the homescreens. Either option works well. The phone also come with a 2A charger as well. For $99, a keyboard and mouse (logitech k400 is awesome!) a few play store apps and a little time to get everything setup just the way you want, you will have a fully functional mobile computer.
When I disconnect my phone I use the rotation app to go back to auto and my phone functions just the way it normally does. Stupid simple.

video decoding method isn't the only cause of lag.
in desktop mode there is quite a performance drop even when not playing any video files.
you can test this with 3dmark, your score will be average when using screen mirroring, but it will drop by 10% when in desktop mode (single screen)
Has anyone possibly figured out a way to disable or remove the Galaxy Note 2's "desktop mode" switch? I have a USB mouse which I would love to use with it (don't want to spend extra $ on a bluetooth mouse), so I was thinking that the problem could be solved if the automatic detection of the mouse and subsequent switch to "desktop mode" could be disabled somehow. Thoughts?
