according to some redditor the limits are

one monitor 8K 60Hz | one monitor 4K 120Hz | three monitors 4K 30Hz | three monitors 2K 60Hz

which makes a lot more sense to me than a hard limit. driving displays as far as graphics processors are concerned is just a matter of data bandwidth. so the more pixels you want to drive the fewer monitors you will be able to run

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.

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).

If that handoff from internal audio hardware to the AUX jack is done in firmware (which is pretty common these days) you’re probably SoL. Seems like a first generation oversight. There is no reason why the internal mic couldn’t be used. The isolation from the game audio is even better than when the internal speakers are playing the sound.
