Compatibility Information
Supported Source Devices
- Desktop PC, Gaming PC, Laptop with DisplayPort 1.4 (NVIDIA RTX/GTX, AMD Radeon)
- Workstations with dedicated graphics cards
Supported Display Devices
- 8K/4K TVs with HDMI 2.1 input port
- Gaming monitors (HDMI 2.0/2.1)
- Projectors with HDMI 2.1 input port
- HDMI 1.4 compatible devices (lower resolutions)
Note:
Not compatible with KVM switches, docking stations, Hubs, PlayStation, or Xbox consoles.
8K/4K high refresh rates require a compatible GPU, HDMI 2.1 display, and certified high-speed cable.
The achievable resolution and refresh rate depend on DP host devices and output devices. For example, if your DisplayPort host device supports 8K@60Hz, while the connected display only supports 4K@60Hz, you can only get output 4K@60Hz rather than 8K@60Hz.
