Extreme Performance Benchmarks
DC505 has been successfully tested to support:
— 4K @ 144Hz
— 2K @ 300Hz
— 1080P @ 480Hz
With AMD 6000 series or newer GPUs, the fuser can reach:
— 4K @ 160Hz
— 2K @ 360Hz
— 1080P @ 600Hz
(Note: Nvidia cards are limited by enforced DSC compression protocols, which may prevent reaching maximum refresh rates. This is a GPU-side restriction, not a fuser issue.)
** Ultrawide is supported however performance may vary depending on your monitor.
