Arnova devices currently lack HDMI output, but some of the device cases clearly show a plastic cover the size of an HDMI connector.
Side of the Arnova 10 show HDMI spot circled in red.
Our forum user p1ceus was curious enough to disassemble his tablet to see what was behind 
According to his findings:
there are already prepared holes and pins for miniHDMI connector!
According to this pinout, I tried to measure at least voltage and voila, it is under power
Closer look at the mother board.
In addition, it’s interesting to note that the Arnova 10 G2 device seem to already have software support for HDMI output, see following system files already present in current device firmware:
system/etc/permissions/android.rockchip.hdmi.xml
system/frameworkandroid.rockchip.hdmi.jar
system/frameworkandroid.rockchip.hdmi.odex
system/lib/hwhdmi.rk28board.so
system/lib/librockchip_hdmi_jni.so
We’ll keep you updated about the success of this project and see if it can also be done on other tablets.
Please note than opening your tablet case may void the device warranty.

Computer Engineer here. Is there still interest in this mod? Looking at this image () there are potentially 11 RES, 3 CAPS, 2 UNKOWN (diode, cap, etc), and the MINI HDMI connector. So 17 parts. They shouldn’t be to tough to figure out if I know what is driving them.
Anyone have schematics or pictures without those heatsinks/metal plates attached?
Where can I buy the HDMI component to install?
I don’t think this project has brought any feedback of installation success, so it’s probably not worth trying to follow, unless you have some time to spend and really know what you are doing.
Has anyone tried this hardware mod yet?
I’m curious to try this one out but am a little concern that it wont work
can you explain how you removed easly the cover please
I had to repair my charge port, and when I open the case I noticed this aswell. The question I have is where would you by such a part? I checked the firmware file and every thing seems to be in order to run HDMI. All we’d.need is to put one in and try it. I’m sure we could make a driver if needed.
From what I can see from the photo it looks as if it may be this one (no guarantee on that though):-

if anyone wants to give it a try. Let us know how you get on.
I see the 5 screws on the back, but then can’t get the back off, any pointers.
I’ve only had mine a few weeks, don’t really want to mark it too much yet.
You may want to have a look here:

Thanks for that.
As you will have noticed I needed to correct a mistake in my first comment, is it possible to edit a previous comment rather than have to post another ? (like I did).
Sorry but it’s not that one, that’s standard size.
It’s a mini receptacle so therefore could be it’s this one:-

(Like I said, no guarantee on that either)
How you removed the cover after removing the screws please
