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](http://www.cablematters.com/pc-831-118-certified-cable-matters-thunderbolt-3-to-dual-4k-or-single-5k-displayport-adapter-for-mac-windows-computers.aspx) from [Amazon](https://www.amazon.com/gp/product/B01DYFI1OE) 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. **Specifications** - 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.
