Of course i can connect my PC to an 8K TV and a home cinema. But for that you need to have it.😉 My home cinema was ~20k when i bought it. My amplifier is a bit older but still bonebraking. My speakers are Canton Ergo Series. Front, Rear, Center and Sub. It is an active one. My speakers are Bi Amping compatible. Yes If i connected a PC to my home cinema i could use it as a Blu Ray Player. But for me there is no need for that. I user a 4K BD player, a Series X and a PS5Pro. I use my 4K BD Player for Youtube, (4k) BD, DVD, CD but i could download movies, use Streaming plattforms like Netflix as well if i wanted. I play games on PS5 and the Xbox SX. The Switch i use for Handheld only. So i got everything i need!😎
