Mini DisplayPort to HDMI 2.1 cable

This Corn Electronics cable connects a Mini DisplayPort source to an HDMI 2.1 display. It supports 8K at 60 Hz and 4K at 144 Hz for high-resolution video. The aluminium shielding protects signal integrity. It is suited for users linking laptops or desktops to modern monitors or televisions.

Check your source port and HDCP support

Verify that your computer provides a Mini DisplayPort 1.4 output rather than a standard DisplayPort or USB-C connector. The cable requires HDCP 2.3 compatibility on the source for protected content. Confirm your graphics driver can output the desired resolution and refresh rate combination before ordering.

Sustained 48 Gbps bandwidth with HDR and VRR

The link maintains 48 Gbps total bandwidth for continuous 8K or high-refresh 4K playback without compression. Static and Dynamic HDR metadata pass through alongside Variable Refresh Rate and Quick Frame Transfer. Enhanced Audio Return Channel and 32-channel audio remain synchronised during extended sessions.

Questions about this item

Does the cable include both Mini DisplayPort and HDMI connectors or must I buy an extra adapter?

The cable has two connectors built in — one Mini DisplayPort plug and one HDMI plug — so no separate adapter is required.

Which resolution and refresh-rate combination should I pick for an 8K monitor?

For an 8K display the cable supports 7680×4320 at 60 Hz or 30 Hz; choose 60 Hz for smoother motion if your source can drive it.

What does the 48 Gbps bandwidth mean when I connect a laptop to a 4K 144 Hz screen?

The 48 Gbps total bandwidth carries 4K at 144 Hz with HDR, VRR and eARC audio without compression.
