SIIG DisplayPort 1.4 to HDMI 8K Adapter

The SIIG CB-DP2611-S1 is an adapter that converts a DisplayPort 1.4 output into an HDMI input, giving your computer or graphics card a direct path to 8K or high-refresh-rate 4K displays. It is unidirectional, so it sends the signal from DisplayPort to HDMI only, making setup straightforward and reliable.

This adapter delivers up to 8K resolution at 60 Hz and up to 4K at 120 Hz with HDR support. When paired with a graphics card that supports Display Stream Compression 1.2, it maintains full image clarity and smooth motion, which is especially useful for competitive gaming, detailed video editing, or immersive home theater viewing.

The housing is built with aluminum to manage heat and withstand daily use while keeping the adapter small enough to travel with your laptop or fit behind a wall-mounted monitor. Power comes through an included USB connection, so there is no bulky external supply and no software to install—simply plug it in and start working.

Compatibility is broad. The adapter works with desktops or laptops equipped with DisplayPort 1.4 outputs, including systems that use NVIDIA RTX GPUs and Intel Iris Plus graphics. It is equally at home in a creative studio driving a color-critical reference monitor, in a conference room linking a work laptop to a large HDMI projector, or on a gamer’s desk pushing a high-refresh-rate 4K panel.

SIIG backs the CB-DP2611-S1 with a two-year warranty and responsive support, so you can depend on it for long-term projects and daily tasks alike.
