The Plugable Thunderbolt 3 Dual HDMI Adapter allows Thunderbolt 3 PC's to connect to two 4K HDMI displays. We decided to try this with the Razer Blade Stealth which supports Thunderbolt 3.
First we made sure that the Razer Blade Stealth was updated with the latest updates using the Blade Stealth Updater program.
After we connected the Plugable Thunderbolt 3 Dual HDMI Adapter to the Razer Blade Stealth, we then approved the adapter to always connect with the Razer Blade Stealth in the Approve Thunderbolt Devices window.
Unfortunately, the Razer Blade Stealth is unable to display to any 4K TV's that we tried through the Plugable Thunderbolt 3 Dual HDMI Adapter. This is probably related to the issue we saw in an earlier review where the Razer Blade Stealth does not have enough DisplayPort lanes connected to the Thunderbolt 3 link.
