Good day to you all. I found this 4K Upscaler device on amazon: https://www.amazon.com/dp/B07CP138D6/ref=cm_sw_r_cp_api_glt_fabc_QJ04PHABEVA83RVZWTYY?_encoding=UTF8&psc=1 and I wanted to know do devices like this increase resolution of any video to 4k? I have a Formuler GTV device with an IPTV subscription that has live channels streaming from all over the world. Anyways, the majority of the channels are at 1920x1080. My TV is a 4K HDR TV which has no problem playing these channels. However, I wanted to know if I hooked up this upscaler device, will the resolution of those 1920x1080 increase to 4K?? Will the picture quality look any better?? I only asked cause the price is high and I wanted to be sure before I make the purchase. Thank you all.
