Error 400 is usually caused by multiple monitors plugged into the PC. Make sure that the link box is plugged into the same graphic card with the main monitor. You can change which is the main monitor in right click – display settings. If it is still not working, unplug other monitors. Try updating the graphics driver as well.

Had this worked before?
The specs you listed are unfortunately below the threshhold for a VR ready machine (I'm not saying this is the cause) and once the output does come out it will potentially result in a poor experience because of how the 960m is configured (which has 2GB of memory if I recall for that chip in that laptop).
Take a look at this thread on nVidia for an explanation of the implementation (optimus link to the internal GPU): https://forums.geforce.com/default/topic/937700/nvidia-960m-and-steamvr-performance-test/?offset=3
With that said, try the below and let me know if it gets you closer to working:
Use USBDeview to manually uninstall drivers
USBDeview is a free tool that is automatically included with the installation of SteamVR. The default path to this tool is …\Steam\steamapps\common\SteamVR\tools\bin\win32\thirdparty. This tool allows users to manually inspect all USB devices that have installed drivers, and is useful when it is suspected the Vive drivers are not being removed using the SteamVR ‘Remove all SteamVR USB Devices’ feature, or when it is believed there may be conflicts caused by other USB devices. Non-Vive related USB devices should only be uninstalled in this way if there is believed to be a driver conflict caused by another USB device.
Removing Vive USB Drivers
Make sure direct mode is enabled. Make sure to plug in directly to the USB on the machine and not via a hub just to make sure no conflicts. Plug the HDMI cable directly from the PC to the linkbox.
Let me know if this provides you with any progress.

The 960M is indeed below the thresholds of what can run VR (Our min spec is a GTX 970 and we're now recommending a 1060 nowadays). Laptops with onboard graphics handle HMDI output in weird ways and thus you may have some luck playing with direct/extended modes. That said, if you do get the compositor to successfully detect your graphics card, I wouldn't expect usable performance out of a 960M. The 960M benchmarks at about a third of what the 970 benchmarks at for comparison.

USB 2.0 or 3.0 ports? Try using 2.0.

None of the steps in this thread have worked for me. It's getting pretty frustrating, especially because this isn't a cheap purchase. If there are no fixes for this, it'll be an easy reason for me to preach to people to NOT purchase this product, unless you want to throw away close to a grand.

I appreciate that it's frustrating. Every set up is unique, are you asking for assistance?
Please tell me more about your set up (OS etc.)
Can you also double check and confirm whether the Vive is being detected as a monitor? Right click desktop-->display settings.
