I recently picked up an MB16AMT as an additional monitor for my MacBook Pro, knowing that there were limitations with using the touchscreen along with a Mac (compared to a PC).

Thus far, I have noticed two main issues (and I believe both are known/identified), and am wondering if anyone has any update/workaround on these, or knows if they are being planned for a future software/firmware/driver update?

• No MultiTouch support (touching the screen only moves the mouse curser, but does not handle MultiTouch gestures or aspects such as scrolling)

• Using the touchscreen, when the display is not the active display, acts as a mouse cursor on the Active Display. Thus, if I'm in another application on my primary display, and do not first move the mouse cursor over to the application on the MB16AMT and click the application to move the active display to the MB16AMT, and taps on the MB16AMT are registered as mouse clicks on the primary display (not the MB16AMT)

I'm open to any/all thoughts, and full well understand that these limitations had been identified before purchasing.

The monitor I have only has a USB type C connector and not a separate port for power. It works connected to the port on my laptops which supply video and power via the single cable, however I would like to connect it also to my desktop PC. Is there any adapter for instance that splits into power and USB C that I can use or any other way of doing it?

This is my first Reddit post, even though I've been using the internet for decades.

Hey everyone,

I’m currently working on a DIY multi-monitor setup using brand new laptop displays and controller boards.
For this project, I bought two complete brand-new display assemblies from an Asus Chromebook C423NA (Touchscreen version), along with two new 30-pin eDP controller boards from eBay.
My goal is to build a triple-monitor setup that matches the look of my main laptop screen.

However, I’ve run into a pretty big problem:

The touchscreen version of this Asus display is completely sealed and glued together, which means I can’t access the 30-pin eDP connector on the back of the LCD panel itself.
The connector is embedded between the LCD and the touchscreen layer, so it’s not reachable without physically opening or damaging the panel.

To make things more complicated, I also can’t use the original display cable from the laptop.
It’s a multi-layered, shielded eDP cable with proprietary Asus connectors on both ends — neither side fits a standard 30-pin eDP controller board.

So basically:

• I have the displays,

• I have the controller boards,

• but I can’t connect them together because the internal eDP port is inaccessible.

What I’m Trying to Figure Out

I’m wondering if there’s any safe way to make this work — for example:

• Opening the display assembly carefully to reach the internal eDP port and connect the controller cable directly, or

• Finding some kind of adapter or extension cable that can bridge between the Asus proprietary connector and a standard eDP 30-pin connector.

I’m aware that opening a glued touchscreen panel can easily damage the glass or digitizer, but I’m curious whether anyone here has tried it before — especially with the Asus C423NA touchscreen or similar Chromebook panels.

Technical Details

• Device: Asus Chromebook C423NA (Touchscreen version)

• Panel type (likely): BOE NV140FHM-N63 or similar 30-pin eDP panel

• Controller board: Generic eDP 30-pin HDMI/VGA controller board (brand new)

• Goal: Use both displays as external monitors for a clean triple-screen setup

Questions for the Community

Has anyone here:

• Opened this particular panel (or a similar Chromebook touchscreen) successfully?

• Confirmed whether the internal eDP connector is safely reachable?

• Or found a compatible adapter cable to go from the Asus proprietary connector to a standard 30-pin eDP plug?

Any tips, insights, or experience would be really appreciated! 🙏
I’d love to know if it’s realistically possible to use these brand-new displays with standard controller boards without breaking the touch units.
