A:AnswerHi Alex,
If these do have speakers built in I have yet to figure out how to get them working. My PC shows the monitor as an option for audio but I have tried it and no sound is produced. Not sure if that helps but that is my experience! Otherwise though I love the monitor as I have my PC in a shared space so I am using a headset anyway.
Thanks,
Jbeeb
A:AnswerMAG27C has the following:
1x DP(1.2)
1x HDMI(1.4)
1x DVI
This isn't a 4K or even 2K display so 2.0 wasn't necessary. If it's an issue regarding incompatibility, they're backwards compatible, but 1.4 will limit the display quality on higher resolution displays. HDMI can only output 60Hz, if you want 144Hz a DisplayPort cable is necessar. This display comes with both.
