A:AnswerNo, the Alienware AW2525HM gaming monitor does not have built-in speakers. If you need audio, you’ll have to use:
External speakers or headphones connected to your PC.
Or use the monitor’s audio-out jack (3.5mm) to route sound from HDMI/DisplayPort input to external speakers.
A:AnswerHDMI 2.1: Up to 255 Hz at Full HD (1920 × 1080) So, if you want the full 320 Hz, you’ll need to use DisplayPort. HDMI is still very fast at 255 Hz, which is excellent for most gaming setups.
