DisplayPort 2.1: 16K를 위한 준비
80Gbps 대역폭이 상상하기 힘든 해상도의 문을 열어줍니다.
## UHBR Signaling Modes
DP 2.1 introduces Ultra High Bit Rate modes:
- **UHBR 10**: 40 Gbps (4 lanes × 10 Gbps)
- **UHBR 13.5**: 54 Gbps
- **UHBR 20**: 80 Gbps (4 lanes × 20 Gbps)
## Resolution Support
| Resolution | Refresh Rate | Mode |
|---|---|---|
| 4K (3840×2160) | 240 Hz | UHBR 13.5 |
| 8K (7680×4320) | 60 Hz | UHBR 20 |
| 16K (15360×8640) | 60 Hz | UHBR 20 + DSC |
| Dual 4K | 120 Hz each | UHBR 20 |
## Panel Self-Refresh 2 (PSR2)
DP 2.1 supports Panel Self-Refresh, reducing power by only sending changed pixels. Essential for laptop efficiency and OLED burn-in prevention.
## Adoption Timeline
AMD RDNA 3 GPUs support UHBR 13.5. Full UHBR 20 will arrive with next-gen GPUs. Monitors supporting DP 2.1 started appearing in 2024.
