Update #2 []: As highlighted once again by Digital Foundry's Oliver Mackenzie, this text has now also apparently been removed from Nintendo's European websites.
Once again, we've reached out to Nintendo for clarification about all of this and will let you know if we hear anything back.
Update #1 []:
[Thu 17th Apr, 2025 06:15 BST]: Just weeks after the full reveal of the Switch 2, Nintendo has reportedly updated a description on its official websites in the US, Canada, and Japan (via Nintendo Everything).
As highlighted by Digital Foundry's Oliver Mackenzie on social media, "VRR support for TV play" is no longer mentioned. It's worth noting how other areas of the site in this region still reference VRR and Nintendo's official Tech Specs page also still lists "VRR up to 120 Hz" for the console's built-in screen.
The Nintendo Switch 2 webpage in other regions like Europe still have "The system also supports HDR, VRR, and frame rates up to 120 fps on compatible TVs."

You can see the original story about Nintendo Switch 2 supporting variable refresh rate below. Hamster's Arcade Archives 2 page for Ridge Racer also references it.
