I use it to play the cartoon DVDs for my grand child that I get at WalMart. Works great for that. Not sure about Bluetooth and I haven’t tried blueray.
I honestly don’t know. I’m not very computer savvy. I bought it for a smart tv but I will say that I have to select “computer” on the tv input to get it to work. Doesn’t recognize as HDMI. Hope this helps in some way.
