Wrong.
My STB is NOT 4K.
The Resolution Settings of my STB maxes out at 1080p.
Different STB models provided by Jio at different points in time have different Resolution Settings. I am a relatively old customer. My father bought our Jio Fiber connection during the early stages of trial run, in May 2019. As such, we were provided with the STB as immediately as Jio Fiber introduced paid plans. Meaning, my STB is one among Jio's earliest STB models. Hence the resolution restriction. They had not started rolling out 4K STBs at that point. I am more than sure, that there are a bunch of older Jio Fiber users like me here, whose STBs aren't 4K compatible. We had already discussed about it in detail in other threads of this Jio Fiber forum. One can still read those threads if they have the patience to scour through the myriad of threads in the Jio Fiber forum.
P.S:
My TV is 4K, which supports HDR 10. So, there is no way that my Jio STB is secretly 4K.
