A:AnswerThis is a monitor, not a desktop computer. If you need speakers, I would suggest purchasing them at Best Buy. They have a wide variety of speakers to suit the needs of most people.
A:AnswerThank you for the question. The specification indicates the power supply required is 100 - 240 VAC 50/60 Hz. The display scan frequency (horizontal) is 30-86 KHz and display scan frequency (vertical) is 48-75 Hz.
A:AnswerIt uses HDMI cable to hook up to the computer. So if your computer has a HDMI port it should work. But Best Buy is always wonderful with their return policy.
