Powering a portable monitor with the dock.

[nr952007]

I have an LG Gram View+ portable monitor that I use for work. I'm trying to figure out if I will be able to use this dock with the screen. The issues I'm trying to resolve are:
1) The monitor only accepts USB C, I see this dock has no USB C out.
2) Does the dock support DisplayPort Alternate Mode (DP Alt Mode) and will it have a power output (USB PD) at 7.5 W (5 V / 1.5 A) or higher? Im trying to figure out if an HDMI or DisplayPort to USB C adapter will provide enough power to the screen. It does not have an internal battery and im not sure about power pass through.

Any insight will he greatly appreciated.

As to 1)

According to the website, the USB-C port is PD with passthrough only:

"USB-C power delivery passthrough input"

So you appear to be out of luck with that.

I has USB 3.0, so I'd imagine a USB-A to USB-C cable that is at least 3.0 should work. Now does that offer DP Alt Mode? I do not know. I too am curious.

Why not plugging the monitor directly into the Deck?

That does work and I have tried it. However, the montior drains the battery of the deck significantly.

I see. As per the official specification, the dock will output DP over a DP plug, the USB-C receptacle is only for charging.

I'm pretty sure the USB-C to HDMI/DP adapters only work by providing signal from USB-C to the HDMI/DP, not from HDMI to USB-C.

with the current specs, either get a USB hub for the 3.1 or a simple dongle for USB 3.1 to usb-c... not rocket science. You can get them on amazon for like 6-12$ i have like 4 of them. USB C female to USB 3.0 Male

Can you confirm that USB 3.1 Gen 1 supports display? At what resolution? What power can it deliver? I agree it is not rocket science, however I'm not trying to spend 80 dollars if this particular dock can't do what I need it to.

USB-A doesn't support display at all and the USB-C receptacle is only used for power.

Hello,

I'm in the same boat trying to get my ASUS MB16AC portable monitor ( https://www.asus.com/ca-en/displays-desktops/monitors/zenscreen/zenscreen-mb16ac/ ) working with the SD (Steam Deck). The portable monitor has a single USB-C port and the SD has a single USB-C port.

1) direct connection between SD and the monitor using a USB-C cable (both ends) works however this drain the SD's battery, same issue as what the OP reported in this thread.

2) connecting the monitor via the official SD docking station (and a third party docking station) using either the HDMI, DP, or USB-A ports would display the following message:

"Your device does not support DP Alt Mode, please install the latest driver and try again."

3) tried the Anker USB C Charger (https://www.amazon.ca/gp/product/B0BDKB4W7N) and still getting the same message as #2.

Which adapter/cable do we need to ensure PD to SD and allow video transmission to the portable monitor? Do we need to install driver on the SD in order to support DP Alt Mode?

Thanks,

Devin

USE SABRENT STEAMDECK DOCK.

[NZ.Zero]

Same problem.
THink i have an answer though... get an HDMI dock and use this.. ? https://www.amazon.com/gp/product/B0B5XBYQSM/ref=ox_sc_saved_title_1?smid=A3HKSDB7SVSEC4&psc=1
Otherwise, a lot of the DP to USB-C cables are bi-directional so a DP dock should do it.

None of their specifications or videos state that the usb-c out can be used for display, just the hdmi. Do you know something that they don't mention?
