Actually a pretty clever, and useful app. Definitely not only for "older relatives". People in my office, in their 20/30/40's, can't even handle the basics. That name though :D
Cool site. I noticed it doesn't know about phones that have USB-C chargers.

edit: also DisplayPort for connecting to laptops

Allthough I find the base concept of the side promising (not only for older relatives), it would be much more helpful if you add more connection types. Some examples:

- "Computer --> TV" only knows HDMI and VGA (E.g. what about [mini] Display Port?) - "Computer --> Printer" only knows USB A to USB B

I would start with the most common possibility and go down to the more exotic ones, to not clutter the expirience for most people. Then you could even add more special connections where you need adapters for.

It doesn't know about any phones which are not Apple and do not have MicroUSB.
cool idea!

Note the first thing I tried (connecting a laptop with DVI, say, an old macbook) to a TV told me it didn't know what cable to use, I would've expected it to show me a DVI->hdmi cable

Or thunderbolt, or display port.
This is awesome! My only suggestion would be that for selections that are incompatible, you should offer an explanation about why they are incompatible. Just having the options greyed out and disabled is really frustrating for non-technical users.

For example: "I want to connect my tablet to the TV". As a techie, I know this is possible, but the solution is probably too complicated. It might be helpful to let the user make this choice, but then say "You can't do this with a cable". Even for stupid ones like "I want to connect my Printer to the TV", just say "This is not possible, you can't connect X to Y".

Micro-HDMI is harder to find, but lets me connect my tablet to my TV quite nicely. The problem is distinguishing it from micro-USB.

(Is there a visual/ML tool that users can use on their phones to identify cable plugs and sockets?)

> For example: "I want to connect my tablet to the TV". As a techie, I know this is possible, but the solution is probably too complicated.

What do you mean? I've plugged in my mother's tablet to the TV on numerous occasions with a mini-HDMI to HDMI cable. Is that uncommon on newer tablets?

Well that depends on the tablet you have, so the next question when you select tablet-to-tv would be "Which tablet do you have"? Because a Nexus 7 doesn't have any HDMI ports, so you'd have to get a Chromecast or something (too technical).
When you select computer to TV, it asks whether your computer has a port like this (this being a picture of a HDMI port.) I see no reason why they couldn't do the same for a tablet.
The HDMI on the nexus 7 2013 works with a MHL cable trough the microUSB port. The 2012 model doesn't have MHL.
Maybe point in the right direction: "you might consider a chromecast <short explanation goes here>"
You're missing a cable I had to buy recently for my father-in-law: Laptop to monitor: mini display port to DVI (specifically DVI without analog pins or it wouldn't fit into the plug on the monitor).
This is one of the few blatant affiliate plays that I'm 100% ok with. This provides a very useful service, I don't care at all that you have your amazon links there. Very very well done!
For Computer => Printer it only proposes a USB cable, but many still-working printers require an LPT2 cable.
You know where this could become really valuable would be in helping people figure out which USB Type-C cable they need. Because of the proliferation of Type-C alternate modes (USB/HDMI/Displayport/Thunderbolt) and power levels, it'll will become common to use a cable that fits mechanically but doesn't function. I predict significant unhappiness!
This is a good idea, but would also take an exhaustive database of individual devices.
That's a rather unfortunate name. Or fortunate, if you're targeting certain audiences.
Found a problem when trying to go for USB-C on Android.

I chose Mobile Phone to computer. It asked if I had an iPhone. I said no. It asked if I had an Android. I said yes. It showed me a picture of a Micro USB port and asked if the connection looked like that. I said no. Then it showed me a picture of an older iPhone with a 30pin connector and asked if I had that.

Can confirm. Dongle Daddy can't currently help me power my Nexus 5x.
Also, if my laptop doesn't have HDMI or VGA, I can't connect it to my TV. Don't some ultrabooks only have Display Port out?
Yes, and even if something has DisplayPort and VGA (like some Thinkpads) you'd probably want to use DP where possible.

EDIT: and I'm fairly sure the suggestion for connecting a VGA laptop to a HDMI TV doesn't actually work that way around.

Indeed -- many TVs have VGA ports, or DVA, and that should be the first option if the computer only has VGA (or DVA) out.

You can buy a VGA to HDMI adaptor, but I haven't tried one.

Not just ultrabooks, while my XPS 13 obviously only has a mini-DP my big chunky W540 from work only has one as well (the dock has one, but chances are consumers aren't going to buy a $150 dock for their TV when a $20 mini-DP to HDMI cable will do just fine).
Also... there are still people out there with phones that have the older Mini-USB socket.
> "If your phone is made by Samsung, HTC, Sony, Motorola, LG, Nexus, Nokia or Google it's definitely an Android phone. If you have an Apple iPhone, it's definitely not an Android"

Just a heads up, my Nokia running WP is definitely not an Android phone.

Ditto for my wife's HTC Windows Phone 8X.
Good idea, but I noticed some issues:

IMHO it would be useful if at least the result pages had permalinks so you could copy and share them.

I think the adapter suggested for "laptop with VGA" to "TV with HDMI" does not work that way around, which is exactly the kind of mistake this site should help to avoid.

As others have noticed, (m)DP is fairly important and missing.

given the watermark, you are probably not allowed to use this image on your site in this way https://www.dongledaddy.com/images/tv/hdmi.jpg

It's worth pointing out that the results might be hidden if you've got an adblocker enabled. Took me a second after the result appeared to figure out why there wasn't any product link like other comments were mentioning.

Neat idea though. Almost makes me wish I had some tech illiterate people in my life so this could save me tech support.

Also, small suggestion: "TV" could reasonably be named "TV/Monitor/Projector".

Ah, I was wondering where the link was, that explains it.
Great idea, but many common connection options are missing. Connecting TV with HDMI to computer asks only about full size HDMI and VGA and then gives up. No DVI, no display port, nothing else.
This is really nice. If you are looking to expand, I would like to see more audio equipment included, such as synthesizers, mixers, and computer audio interfaces. I've recently been struggling somewhat with the difference between mono, balanced mono, and stereo connections as I try to set up a small home studio.
Older people often have older hardware since they don't feel the need to change what works. My first search for a common older printer connector (USB AB) didn't work:

I found it immediately:

  I want to connect my... Printer/Scanner
  to my... Computer/Laptop
  Printer/Scanner connection: USB B
  Computer/Laptop connection: USB A

  You need this cable
  USB 2.0 A-Male to B-Male

No option for phones using usb c
I like it and the name is a nice combination of memorable and provocative.

Should add a Phone => Computer guide though would be more specific to the model type (ex: may need a Lightning to HDMI adapter).

Love the idea, you can may be add YouTube link witg the result to show how to connect the two devices.
There is no way I am showing my grandfather this. He'll surely do it wrong and blame me. Even when I do all the work for him, he gets confused, tells me I did it wrong, redoes it himself, and then blames me when it doesn't work...

Last time I tried to help him, we argued for an hour about the difference between an HDMI cable and a high-speed HDMI cable...

My clients, on the other hand, will love this tool.

I dare you to add a "Live Chat" or "Live Video Help" button. :)

Charge by the minute and see how long your patience lasts.

Back in college I made an application similar to this: http://mymanual.herokuapp.com/ (sorry if its slow or broken, unmaintained for ~3 years).

I had to do an input for each device and tag the ports so the logic in the application can create custom setup guides.
