8K Flexibility Across Standards
Bridge the gap between 8K DisplayPort and HDMI with the Cable Matters 8K DisplayPort 1.4 to HDMI 2.1 Adapter. Effortlessly convert a DisplayPort port on a gaming PC or multimedia system to an HDMI connector for a television or monitor. Maintain support for the latest HDMI standards, including 4K@240Hz and 8K@60Hz support.
Important Notes
- For dedicated graphics, an Nvidia RTX 2060/3060 or an AMD Radeon RX 6000 Series or newer graphics card is required to achieve 8K@60Hz video.
- 4K@240Hz and 8K support may require a firmware update on some 8K TVs.
- 4K@240Hz and 8K support must be manually enabled on some 8K TVs.
- VRR/G-Sync/FreeSync are not supported.
Is this adapter bidirectional?
No. This adapter only works from DisplayPort (computer/GPU) to HDMI (monitor/TV). It does not convert HDMI sources (like PS5/Xbox) to DisplayPort displays.
Does this adapter support VRR, G-Sync, or FreeSync?
No. It does not support VRR, G-Sync, or FreeSync. It supports fixed refresh rates up to 8K@60Hz, 4K@120Hz, or 4K@240Hz on compatible GPUs and displays.
What should I do if I don’t get the expected resolution or refresh rate?
Make sure your GPU supports DP 1.4 with DSC, your display supports the resolution/refresh rate, and your drivers are updated. Use a certified HDMI 2.1 cable. For help, search “Cable Matters 102101/102103 Troubleshooting Instructions.”
Does this adapter work with gaming consoles like PS5 or Xbox?
No. It is designed for DisplayPort-equipped GPUs only and is not compatible with PS5, Xbox, or other HDMI source devices.
Why do I see flickering or color distortion?
This is often caused by signal loss from long or poor-quality HDMI cables. Use a shorter or certified HDMI 2.1 cable, or lower the resolution/refresh rate.
