Hi, just wondering if the title is possible. I’m currently daily driving my steam deck as my work pc in my office. mostly i used it to stream programs off my much beefier main pc at home.
Recently I’ve been thinking of adding a drawing tablet to the setup (wacom movink) but it uses usb c to c and the dock only has one for power. so if i used an adapter (usb c to usb a), would it work?
cheers.
in my experience the official dock has trouble with just one monitor. i couldn’t imagine trying to configure 3.
when i boot into desktop mode with the official dock, there’s a 50-50 chance that it just doesn’t load the image at all on the monitor and i have to take it off the dock and just use desktop in handheld mode.
maybe a better splitter or connection could do it. but the official dock seems to have a lot of issues with USB inputs in general.
I think it would struggle to have the bandwidth to pull that off, but maybe if you keep the resolution and refresh rate down. And that’s assuming USB-C to USB-A would work in this case, which I don’t know the answer to.
I assume the tablet gets its video through standard HDMI/DP over USB-C, hence a USB-A to C adapter wouldn’t work.
If you still want to use the tablet with the official dock, there may be HDMI+USB -> USB-C adapters capable of inserting the HDMI signal into the USB-C connection. I’m not too knowledgeable on this topic, so you may want to resort to some more research of your own.
Also keep in mind (as far as I’m aware) there’s a hard limit on 2 external monitors, unless you use some “trickery” like DisplayLink.
Edit: I’ve done a bit more research and I’m pretty sure that more than 2 monitors are supported. There are two limiting factors here:
- The GPU in the Steamdeck (custom APU which I didn’t directly find a spec sheet for), will typically have a max of 2-4 displays
- The physical connection, AFAIK as the Steamdeck only has one USB-C port, this means it has one DisplayPort 1.4 link available. This link can be divided into multiple video streams. I couldn’t find a table for DisplayPort 1.4, but this website has one for DisplayPort 1.2, suggesting you should be able to run four 1080p60 signals at the very minimum.
Now with all this information, as long as your Steamdeck can output to any three screens (ie. two external ones and the internal steamdeck screen), it should also be possible to output three 1080p60 signals to external monitors.
An external GPU may be the way to go. Doesn’t have to be a beast of a GPU. Probably best to find one thats AMD for easy compatibility. You could also find one that has the amount of connections you need.
So the setup is currently two external monitors? Or does that include the Deck monitor? Is the USB connection to the Wacom just for pen input or does it transfer image as well? If USB-C is used as the monitor port it most definitely will not work with USB-A of any kind. Not even USB-A 3.1. You either need a different dock with a USB-C port or you need the Wacom Link Plus (which means you probably also need a different dock with at least 2 HDMI ports or one HDMI and one DisplayPort).
i forgot to specify. yea, currently im running two external monitors. one 1080p and the other is 1440p.
the wacom movink is a display tablet with pen touch so i’d assume basically an external monitor hence the third monitor.
thats a bummer, thanks for the info.
Ah yea I didn’t realize the official dock has 2 ports for display output. Valve is bae.
There are definitely docks that have 3 display outputs, which would be a viable option if you also buy the Wacom Link Plus. I personally don’t know of any docks that have 2 display outputs and a USB-C port that is display-capable. There may be Thunderbolt ones but Steam Deck doesn’t do Thunderbolt unfortunately.
So yea I guess your only option is a different dock plus Wacom Link Plus. I don’t see any other personally.
thank you for your info. seems like searching other docks is the most cost efficient for me. other commenter said that steam deck has a hard limit of 2 external displays, i cant find info if its true or not.
