Question How to get my VIZIO SV420M to run at 120hz?

[Nathan Brewer]

Hello! I recently got an HDMI 2.1 cable that supports 120hz as on the front of the TV below the VIZIO logo it says 120hz. After plugging it in I'm noticing in windows that it is still running 60hz. I've gone into the Nvidia Control Panel and the Windows 10 advanced display settings that it wont go any higher than 60hz. Is there any way to fix this?

My GPU is a GTX 1660 (Not a TI or Super, just a regular 1660)

I know the 1660 uses HDMI 2.0, and correct me if I'm wrong, but HDMI 2.0 should still be able to still run 120hz on an HDMI 2.1 cable.

Is there any fixes? Thanks in advance!

Just looked up specs for that model tv. It's a 1080p/60hz panel that has motion interpolation to fake 120hz. It is incapable of using a native 120hz signal.
