Steam Dock only works with TV when the Power is Unplugged

[Gozer1003]

Steam Dock only works with TV when the Power is Disconnected from the Dock. When the Power is connected to the Steam Dock my TV says no Signal Detected, when I unplug it, it immediately works (the Power Cable Connected to the Dock, not the cable that connects to the Deck to the Dock). Tried pretty much everything I've seen online over the Months since I got this in order to resolve the issue, but to no Avail.

Strangely though it works fine when in Desktop Mode for some Reason (with the Power Connected), but reverts to no signal detected on the TV when switching back to default mode. I've had a little success with one method that involves unplugging everything then Plugging everything back in, but this has only worked a few times.

Note: I've had this issue since I bought it in June and I have also tried every HDMI Port on the TV.

Note: When I got it the Dock Firmware was updated, Also the Deck Works fine independent of the Dock.

Others I've spoken with elsewhere have suggested this may be an issue with SteamOS 3.5 that did not Exist 3.4, but I've only had the Deck and the Dock Since Last June so not sure in regards to that. Curious if anyone Else has had this Specific Issue and if so if they were able to resolve it.

Are you sure the cable you’re using can support PD

Think Satoru probably hits the nail on the head. This sounds like a classic inadequate cable issue.

Not all USB-C cables (or indeed any cable, but epecially C) are the same. USB-C cables have small chips in that mderate and read the power required, basically.

If you are able to get a picture when there's no power going through it, but not when there is, this would suggest it's unable to handle this power delivery and shuts down to prevent damage.

Simple solution - try better cables.

No I am not, but its not some generic USB-C Cable, it is the official PSU provided with the Dock, and I Don't think it is broken as it will charge the deck independent of the Dock, and charges it with the dock, there is just no picture on the TV unless it is in Desktop Mode, but in Big Picture Mode, Nothing. Note in case it was Unclear, this is not a Generic Dock, this is the Official Valve One.

Edit: Satoru's Link seemed to do the Trick (fingers crossed on it continuing to work)

Note in case it was Unclear, this is not a Generic Dock, I go this one Directly from Valve at the Same time that I got the Deck.
