A:AnswerHi Eion,
This monitor does not have speakers. You'll either need headphones or an external set to hook up to whatever you're using the monitor for.
A:AnswerMonitors like TV's are measured diagonally, and this is a 27" monitor. The reference to the other question was likely talking about the dimensions of the monitor.
A:AnswerThe best way is to place one hand at the top center of the monitor, the other at the bottom center. With a push/pull motion carefully tilt the monitor forward or backwards, taking care not to squeeze the screen.
A:AnswerYes that should work fine. If you have a type-c port, like the ones in the latest macbook line up, you need to buy a converter for Type-B to Type-C
A:AnswerI am using the VGA connection. There are 2 USB ports next to the VGA connection. I don't know about a hub. I'm not very at computer tech stuff. Sorry.
A:AnswerYes, the power cable wind an HDMI cable come included. But I personally got another HDMI since the one in the box was not long enough for what I needed it.
A:AnswerThe monitor is designed for use with a PC, laptop, gaming console, etc. To get 75hz refresh rate, the device to which it is connected must also support 75hz.
