Selore&S-Global USB-C to Dual HDMI Adapter 4K@60Hz

Selore&S-Global USB-C to Dual HDMI Adapter converts a Thunderbolt/USB4-capable Type‑C port into two HDMI outputs, supporting up to 4K@60Hz on compatible devices for expanded screens or mirrored displays.

This compact adapter gives laptops and compatible tablets a simple way to drive two external HDMI monitors from a single USB‑C port. It supports full‑featured USB‑C, Thunderbolt 3/4/5 and USB4 ports and is plug‑and‑play on devices that implement DP Alt Mode and MST (multi‑stream transport) where supported. Keep in mind macOS limits this adapter to mirrored displays only; Windows machines with MST can use independent extended monitors.

How do I set up the adapter with my laptop?

Setup is straightforward: connect both HDMI cables to the monitors, plug the adapter into your device’s compatible USB‑C port, then power on the monitors. No drivers are typically required; the host operating system recognizes the displays through DP Alt Mode or Thunderbolt. If audio remains on the laptop, change the default audio output to the HDMI device in system settings.

• Connect HDMI cables to adapter first, then plug adapter into laptop.
• Use HDMI 2.0 cables for 4K@60Hz output where supported.
• Adjust display arrangement and audio output in system settings if needed.

What resolutions and refresh rates can I expect?

The adapter can deliver up to 4K (3840×2160) at 60Hz when the host device and connected monitor support 4K@60Hz and you use HDMI 2.0 or better. When both HDMI outputs are used simultaneously, many setups will run at 4K@30Hz or 2560×1440/1080p at 60Hz depending on the host’s MST/SST support and GPU capabilities. Verify your device’s specifications for DP Alt Mode and multi‑stream transport capacity.

• Single display: up to 4K@60Hz on supported hosts and monitors.
• Dual displays: commonly 4K@30Hz or 1440p/1080p@60Hz depending on host.
• Requires HDMI 2.0 cable or higher for full 4K@60Hz performance.

Which computers and tablets are compatible?

This adapter works with devices that have full‑featured USB‑C, Thunderbolt 3/4/5, or USB4 ports that support DisplayPort Alt Mode. It is known to function with many MacBook and MacBook Pro/Air models, Dell XPS, Lenovo ThinkPad and other Thunderbolt‑equipped systems. Note: it will not work with USB‑C ports that lack video support (some HP Pavilion and Lenovo IdeaPad models).

• Compatible: MacBook Pro/Air (2017–2021 with Thunderbolt), Dell XPS 13/15/17, ThinkPad T480, select iPad Pro models.
• Not compatible: USB‑C ports without DP Alt Mode (certain Pavilion/IdeaPad series).
• Works only with Thunderbolt/USB4/full‑feature USB‑C ports — check device specs.

Are there limitations on Mac computers?

Yes — on macOS this Selore&S‑Global adapter supports mirrored displays only; macOS does not allow different content on each external HDMI output through this adapter. Windows systems that support MST can extend displays independently. Consult the product manual or customer support for platform‑specific guidance.

• macOS: mirror/repeat display mode only.
• Windows: supports extended (independent) displays if MST is available.
• Contact customer support or download the user guide for setup steps.

Who is this for? If you need a compact, travel‑ready adapter to connect two HDMI monitors from a single Thunderbolt/USB4 or full‑feature USB‑C port — for presentations, multi‑window productivity, or home entertainment — the Selore&S‑Global USB‑C to Dual HDMI adapter is a practical choice. Choose it if your device supports DP Alt Mode or Thunderbolt and you want a plug‑and‑play solution with support resources and a one‑year defective‑product warranty.
