Reddit mentions of C2G 03170 3.5mm Aux F/F Stereo Coupler, TAA Compliant, Black

It's called an aux extension cable with a female coupler. Couples are like 5$(with prime, 2$ without, but you pay shipping), Extension cable is around 7$.

I actually just bought a PS3 last week and had the same questions. Thankfully, while I had no help from others I figured it out myself.

I have a Dell LCD monitor (1920x1080) that I connect to my PS3 with and a set of speakers for audio output.

Mine works perfectly fine and I have never had any problems with display (or any of the horror stories that you mentioned.)

I do not have MW3, but I do have many games that output video from 720p to 1080i to 1080p and they all work fine and look completely natural as you would expect.

Pieces of hardware that you will need:
A HDMI to DVI cable, a 3.5mm Stereo Male To 2X RCA Female Adapter or Y splitter as some people call it, and female stereo coupler if you are going to plug it into a speaker instead of your PC. If just using PC speakers, then you do not need a coupler.

As for monitor recommendations, chose any that have a 1920x1080 resolution and has a DVI connector (most modern monitors should have this as default).

Hope this helps!


Edit: If you have any questions, feel free to ask! I remember how confused I was trying to set everything up.

Here is a video I made demoing my NC Nexus 7 install. It is very basic now. I wanted to see how little I need to get audio working. It isw working better that I expected. Let me know what you think or if you have any questions.

Edit 1:
Parts and pricing(includes shipping) list:

• 2(you only need 1) of these 12v to 5v converter - ~$13 for 2
  
• 1 Right angle OTG cable- $5.75
  
• 1 Male to Male USB cable - $5.00
  
• 1 Metra Din Kit - $21.12
  
• 1 Right angle AUX Cable - $10.43
  
• 1 Female to Female aux coupler - $4.33
  
• 1 Male aux to female RCA cable - $4.50
  
• 1 Male RCA to speaker wire cable - $9.36
  
• 1 Metra wiring harness - $13.37
  
• 1 Pack Command hooks - $9.00
  
• 1 Anti-glare screen protector - $5.95
  
  Total: $88.81 + the cost of a Nexus (2012) which is about $150-$180 depending on which configuration you get. (Note: Timur's ROM only works with Nexus 7 2012)
  
  So $238-$268 grand total.
  
  I also bought a wire stripping and crimping kit - http://www.amazon.com/gp/product/B000K7GRCI/ref=oh_details_o09_s00_i01?ie=UTF8&psc=1
  And a Dremel for cutting the metra bezel and the command hooks
  
  
  I also rooted my Nexus 7 and installed Timur's rom. That was a headache and not needed because you can duplicate the functionality by using Tasker, a Nexus 7 task scheduling app. But to install Timur's ROM basically you need to unlock the bootloader, install TWRP recovery, then install Timur's USB Host ROM. That ROM gives you the ability to plug USB devices like thumb drives into the Nexus 7. It also gives you the option to put the tablet into deep sleep when you turn your car off.

It looks as though your monitor has support for component video, is that correct? If so, I would just use the Wii component cable for video along with the RCA-to-Miniphone adapter you already linked for audio. Unless your "green plug connector" is female, you'll also need a coupler.

Re: the PS3. Looks like you've basically got the right idea. It's really the same premise as the Wii. I don't actually own a PS3, so I'm assuming you already have a way to get RCA audio and HDMI video at the same time?

In both cases, you'll just plug the RCA audio cables into the RCA-to-Miniphone adapter then plug that adapter in to the coupler. Then you'll plug your external speaker plug into the coupler.

You could just get something like this, but I'm not sure I understand - are you talking about plugging the headphones into your car? I don't think it works that way.

To add on to this:

When you want to watch TV on your monitor, you'd have to use HDMI for video and something else for audio. If you want to use external speakers, you can get THIS CABLE and THIS ADAPTER as long as your cable box has RCA audio output.

I couldn't find that adapter on monoprice, unfortunately. Once you have those two, you can easily use any standard speakers or earphones to watch TV, I've used the same combination myself. It would be convenient if there was a 2 Male RCA to 1 Female 3.5mm cable, but i've never seen one of them so you have to use this adapter.

This?

Edit: you might be best off going with the above and a converter like this, since there doesn't seem to be any single cable fitting your specifications.

I have the same setup. What I did was use the little adapter that changes the red/white to 3.5mm headphones jack and plug it in to either the line in port on my computer, which in turn shares the speakers between computer and xbox. You could also get one of these and just join the speaker cable with the adapter.

Possibly one of these, http://www.amazon.com/gp/aw/d/B00DI6HJ5C/ref=pd_aw_sim_23_of_5?ie=UTF8&dpID=310zasE0ZVL&dpSrc=sims&preST=_AC_UL130_SR130%2C130_&refRID=1PE26J7ME90DAQXY31CC

With one of these

But as others have said go check out your local repair shop. They are solely there to provide you with a service of fixing your device cheaper than a new one would cost. Any shop worth it's salt will tell you up front of its to expensive of a fix. Ipod touch does kinda suck to repair as it is solely held together by adhesive and prayers(source:repair shop owner)

I should also mention that

• DVI and HDMI are the same video signal, DVI can carry audio, but it's rarely used. This is why DVI to HDMI adapters are so easy, and cause no loss in quality.
  
• Additionally, DVI can contain a VGA signal in it, most computers will typically do this. Thus most DVI to VGA adapters are doing this, since actually converting a digital DVI/HDMI signal to analog VGA requires an expensive adapter. This means that HDMI to DVI to VGA will not work.
  
• Component is an analog signal that is similiar to VGA, but is missing a part, which is easily figured out by output device. Thus, Component to VGA, is fairly easy and cheap.
  
• Don't forget that you need to get audio from all these devices as well. This and This Would allow you to use a generic pair of headphones for almost any device.

Yeah, mine is a knockoff and it works fine. My speakers have an aux input that I can plug it into, but if not you might need a 3.5mm female to female adapter, and plug your speakers into it like you would with your computer.

No problem. In that case, something like this will do the trick.
