I was looking for an adapter that allows me to output to two external displays using just a single port and I realized that USB-C is not the way to go. USB-C specifications only allow one external display per USB-C port.
So the next logical thing to search is for Thunderbolt 3 adapters and I found the Cable Matters Thunderbolt 3 to Dual 4K or Single 5K DisplayPort Adapter from Amazon retailing for US$79.99 (S$112).
As usual, it doesn’t ship to Singapore directly, so I have to use a freight forwarder like HopShopGo to ship it to Singapore.
- Input Cable: Thunderbolt 3 Male
- Output Ports: 2x DisplayPort Female
- Max Video Resolutions: 2x 4096 x 2160 (60Hz) or 1x 5120 x 2880 (60Hz)
- Adapter Housing (LxHxD): 10 x 6.4 x 1.5 (cm)
- Adapter Weight: 97g
- Cable Tail Length: 27cm
- OS Compatibility: Windows 7.1 and up, macOS 10.12 and up
It seems that this is the only Thunderbolt 3 adapter that works on both Mac and Windows. Other brands like Plugable and StarTech Thunderbolt 3 Adapter works only on Windows.
I am using this adapter on my MacBook Pro 13″ (2017) and I can use a single Thunderbolt 3 port to output to two Dell UltraSharp 27 InfinityEdge Monitors (U2717D) at 2560 x 1440.
