Silkland DisplayPort 2.1 Cable (VESA Certified DP80)
The Silkland DisplayPort 2.1 VESA Certified DP80 cable delivers 80Gbps display bandwidth — required for 4K@240Hz, 4K@540Hz, or 8K output from RTX 5070 and RX 9060 XT GPUs. Older DisplayPort 1.4 cables physically cannot carry the output these Blackwell and RDNA 4 cards produce.

Pros & Cons
Pros
- VESA Certified DP80 — guaranteed 80Gbps bandwidth compliance
- Supports 4K@540Hz, 8K@60Hz, and 16K (DSC compressed)
- Required for full refresh rate output from RTX 5070 and RX 9060 XT
- Compatible with all DisplayPort 1.x devices at lower bandwidth
- Future-proof for high-refresh monitors
Cons
- No benefit on monitors below 4K@144Hz — DP 1.4 cable is sufficient
- DisplayPort 2.1 monitors still limited in availability in 2026
- Stiffer than older DP cables due to higher-spec shielding
Who Should NOT Buy This
Honest assessment
- GPU users who already have a DisplayPort 2.1 cable in the box
- Anyone using HDMI monitors — incompatible standard
- Setups where you don't need 4K 144Hz or 8K output
Our Verdict
Silkland DisplayPort 2.1 Cable (VESA Certified DP80)
This cable is non-optional for RTX 5070 and RX 9060 XT buyers. Both GPUs output DisplayPort 2.1 — the RTX 5070 has DP 2.1a, the RX 9060 XT has DP 2.1. A DP 1.4 cable (the previous standard) caps at 32Gbps and cannot carry 4K@240Hz or higher. If you're buying either GPU and plan to run a high-refresh 4K monitor, this cable costs almost nothing relative to the GPU and is the correct cable.
Frequently Asked Questions
Q1Do I need a DisplayPort 2.1 cable with the RTX 5070?
Yes, if you're running a 4K monitor above 144Hz, or any 8K display. The RTX 5070 has DisplayPort 2.1a outputs. A DP 1.4 cable limits you to 4K@120Hz (with DSC compression) or 4K@60Hz (without). For 4K@240Hz or higher, a VESA Certified DP80 cable like this one is required.
Q2Will this cable work with my existing monitor?
Yes. DisplayPort 2.1 cables are backward compatible with all DisplayPort 1.x monitors. If your monitor has a DP 1.4 port, this cable will work at DP 1.4 speeds. You only gain the full DP 2.1 bandwidth when both the GPU and the monitor support DisplayPort 2.1.
