Questions about this item

My laptop only has USB-C ports — does it need Thunderbolt 3 or Thunderbolt 4 for this cable to work?

The cable works with any USB-C port that supports DisplayPort Alt Mode; Thunderbolt 3 or Thunderbolt 4 ports also carry the video signal, but they are not required.

I still use a 1080p 60Hz monitor — will the cable downscale 4K 120Hz content without flicker?

Yes, the HDMI 2.1 link negotiates the monitor's native 1080p 60Hz timing automatically, so you get a stable image with no added flicker or screen delay.

After plugging the cable into my tablet and TV, how do I verify the link is running at the highest available refresh rate?

Open the TV's on-screen information menu or your tablet's display settings and confirm the active mode shows 4K at 120Hz or the highest resolution and refresh rate the TV reports.
