I've just set up my new 5060 Ti graphics card with my X90J TV. I tried using a Belkin 4K 120 Hz HDMI cable, but I can't seem to get the settings to display 120 Hz at 4K resolution in both the Control Center and Windows. I even bought another cable, the Paugge Ultra High Speed HDMI 2.1b, which supports up to 4K 240 Hz, but now my TV shows no signal when I connect it. It's really frustrating because I want to enjoy gaming at 4K with low latency using 120 Hz.

Make sure you've enabled the 'HDMI 2.1 enhanced format' in your TV's picture settings. It might be under advanced settings.
Just so you know, only HDMI inputs 3 and 4 on that TV support HDMI 2.1. If you're using one of those, make sure you have the enhanced format enabled.
Are you sure you're using an HDMI cable? Double check that it's not a DisplayPort by mistake.
