Question Missing scaling options at 4K/60Hz with Nvidia GPU ?

Jan 5, 2023
Processor: i5-10400F
Motherboard: ASUS PRIME B560M-A
GPU: NVIDIA GeForce GTX 1660
Monitor 1: Dell E228WPF
Monitor 2: PHILIPS 4KTV 65PUS7303/12

I have Philips 4K TV connected to GTX1660 card via HDMI and I'm using the desktop resolution in Windows 10 4K/60Hz. I wanted to try the NIS (image scaling), but it's not available in the NVIDA settings (both control panel and GeForce Experience) unless I lower the resolution or refresh rate to 30Hz.
Likewise, the integer scaling checkbox is missing at 4K/60Hz in adjust desktop size and position and it only shows up when I switch to 4K/30Hz or lower the resolution. Does anyone know why this is happening? Somebody suggested that maybe I'm trying to exceed the bandwidth limitations of the HDMI connection.
But why would I hit the bandwidth limits when I want to use the lower resolution with the NIS (for example 3264x1836/65Hz - 85%) and upscale it to 4K/65Hz? Is there anything I can change (like using a better HDMI cable) to make it work? The native resolution 4K/65Hz works fine.
