Question 1

My monitor supports 4K@240Hz, but the screen goes black when I hit that refresh rate. Is this cable defective?**

Accepted Answer

Likely not. Most modern GPUs require Display Stream Compression (DSC) to be enabled in your graphics driver to push 4K@240Hz or 8K@120Hz. Check your GPU settings—on NVIDIA, it's in the “Manage 3D Settings” menu under “DSC Enable.” If DSC is on and you still see issues, ensure your monitor’s firmware is up to date. This cable is built to spec, but your hardware chain needs to match.

Question 2

Is this cable actually DisplayPort 2.1 certified, or is it just marketing?**

Accepted Answer

Yes, it’s VESA-certified DisplayPort 2.1 with full 80Gbps bandwidth. Many TikTok tech reviewers have verified this with bit-rate testers. However, note that hitting the 16K@60Hz or 10K@60Hz requires both a DP 2.1 GPU and a compatible monitor—current consumer cards like the RTX 4090 support DP 2.1, but most laptops still use DP 1.4. For everyday 4K@144Hz gaming, you’ll be well within spec.

Question 3

Will this cable work with a MacBook Pro via a USB-C to DisplayPort adapter?**

Accepted Answer

It works, but with a performance cap. Most USB-C adapters max out at DP 1.4, limiting you to 4K@144Hz or 5K@60Hz. You won't get the full 2.1 speeds (e.g., 8K@120Hz) through an adapter. For Mac compatibility, a native Thunderbolt 4 to DP cable is better, but for the price, this cable is a solid stopgap if you only need 4K.

Question 4

The cable feels rubbery and not braided. Is it durable enough for daily use?**

Accepted Answer

It’s a PVC jacket, not braided—that keeps costs down while still meeting high-flex durability. Users have reported no signal loss even after months of cable bending behind desks. If you need braided for heavy-duty setup (e.g., cable raceways or travel), consider the Cable Matters braided DP 2.1. But for stationary gaming or office setups, this cable holds up fine.

Question 5

Can I use this with a PS5 or Xbox Series X?**

Accepted Answer

No. Consoles use HDMI output for video, not DisplayPort. This cable is designed for PC graphics cards, laptops, and monitors with DP ports. If you need a cable for console gaming, an HDMI 2.1 cable (like the one included with your PS5) is the right choice. However, some gamers use this with a DP-to-HDMI adapter for 1440p@120Hz—not ideal, but workable in a pinch.

DisplayPort Cable 2.1 5M-DP Cable Supports 16K@60Hz, 10K@60Hz, 8K@120Hz, 4K@240Hz/165Hz/144Hz, 2K@360Hz/240Hz, 80Gbps, HDR, DSC1.2a, FreeSync, G-Sync for Gaming Monitor, Graphics Card, PC
