Acer Nitro 5 AN515-51 laptop display bit depth (6 bit?)

But in the meantime, when I'm searching for the display modes, I get this:





Can anyone tell me what's up with this display? Is it 6 bit indeed?

 

Good surround sound headset

I know you say you're not that guy, but stepping into the $250+ range really brings a change in build quality that might have you never having to buy another set. Otherwise, getting 6 speakers with decent sound in a headset is hard, and that's what you are asking for, and I have no suggestions, but just a bump up the list. *Stick Out Tongue
