I've used HDMI for years with older monitors. However, once I got my 4K monitor with 144 hertz, I finally got with the program, and use Display Port. For me, HDMI 2.1 came too little, too late.
In the convo about movie players. I couldn't believe how so anti PC corporations were, when it came to computer's. You can buy a blueray player for a TV, but forget getting one for a PC, you'll be treated as a pirate, and can't watch movies you paid for.
In the early 2000's DVD era, many of us had fun watching DVD movies on our computer. They usually had extra goodies for people to see or play, for those who used computers as well, it felt encouraged then! Once those Blueray became a thing however, all that changed, they madee it as difficult as possible, corporations hated computer users by that time.
Welle, jokes on them aint it. Selling of movies and shows on Blueray medium, is at an all time low these days, so much so, Sony put out a post, that they made the decision, to stop producing blank Blueray media disks. This is all because, everybody streams content now days. The quality is usually good enough for most people. Blueray not needed, take that greedy citizen hating production company people!
The reality is, the more they fight, the worse it gets for them. Just like Star Trek Starfleet Academy, literally the worst ST show made in history. All time low ratings, and the production company thought they could sail that garbage, but they thought wrong. Produce garbage, receieve garbage ratings, nobody gonna care.
Reality, what a concept.
