It's at the bottom of the specifications: Width 553 mm Length 189.10 mm Height 425.10 mm Weight 5.30 kg

It doesn't really depend on the screens, but rather on the graphics card. What kind of graphics card do you have? Are all your monitors connected to the graphics card? If it's an NVIDIA card, in the NVIDIA control panel you can configure the surround (I don't know the configuration for AMD cards)

Hello, yes, no problem. However, you will have to think about the speaker or headphones.
