Bringus Studios Tecno Pocket Go 10.5" Monitor Mount

This is pretty crummily designed but it does work. It's a very snug fit. The bottom plate is intentionally thin to allow it to flex to grip the controller tighter.

You will need:

• Monitor - https://www.amazon.com/gp/product/B0C7KPPXTZ
• M3 brass heat inserts - https://www.amazon.com/gp/product/B0CZXMT5PB
• Various M3 screws - https://www.amazon.com/gp/product/B07VNDFYNQ

Unfortunately, the monitor can't receive video from the Pocket Go over a single USB-C cable. Because of this you'll need either:

If you are ok with using both USB-C ports on the device:

• 1x USB-C cable
• 1x USB-C to HDMI adapter
• 1x HDMI cable
• 1x HDMI to mini-HDMI adapter

If you want one free USB-C port on the device: 

• 1x USB-C cable
• 1x USB-C dock with HDMI out and a USB-C port
• 1x HDMI cable
• 1x HDMI to mini-HDMI adapter

My recommendations for a dock and cables that are pretty short in length:

• Dock - https://www.amazon.com/gp/product/B0BR3M8XHK
• USB-C cable - https://www.amazon.com/dp/B0CFZNZN25
• HDMI cable - https://www.amazon.com/dp/B0C2PFNXDV
• HDMI to mini-HDMI adapter - https://www.amazon.com/dp/B07VXPW3BZ

A couple of right-angle USB-C adapters help hide the cabling too:

• 90 degree USB-C adapters - https://www.amazon.com/dp/B0B2NJ3P3L
