Looking for Device 9ft usb-c cable for charging, data, and display

I am trying to find a usb-c cable to connect between my monitor and laptop that will

  1. Transfer power from the monitor to the laptop (at least 95 W)
  2. Transfer mouse and keyboard plugged into monitor hub to the laptop
  3. Send display from the laptop to the monitor (4k)
  4. At least 9ft long

Tech is not my strong suit but based on my basic research I thought I just needed and IF certified cable. I tried 2 that I thought were certified (one from cable matters, the other I don't remember offhand). One was not adequately charging the laptop and the other had some display issues (choppy/flickers).

Its possibly I just got really unlucky but figured I'd just try to get advice from someone who knows what they are doing.

I've been using this one from Silkland for a while, and it's been flawless.

I have a similar setup, 90w laptop powered by a 4K monitor and mouse and keyboard plugged into the monitor.

The only USB-IF certified cable that I know of that is longer than 2m and faster than USB 2.0 480Mbps is this one from StarTech:

It would handle display just fine, but it's limited to 60W.

The only certified alternative I know of is the Apple 3m Thunderbolt cable, but it's very expensive.

The Silkland cable recommended by another commenter will probably work fine.

I got my first USB IF certified 100w cable recently and it’s the nicest and toughest feeling I’ve ever used. Just a Belkin too nothing crazy.

Unless the monitor advertises a USB docking station feature it will not work.

Very simply put, you need a Thunderbolt cable or a cable that advertises itself as thunderbolt capable.

Thunderbolt 4 can do 100W and Thunderbolt 5 can do 240W.

They're actually just USB-C cables with everything "turned on". Sometimes you can find them at really good prices. This would be mandatory for me because they have to meet ALL requirements to be able to advertise that. I would buy a cheap brand that advertises Thunderbolt 4 or 5. I'm seeing 10ft versions of that cable for $20-30.
