## Questions & Answers

**Q: I plugged this into my laptop, and it is only displaying 30 hrtz. using hdmi. anyone have the same issue?**
A: Yeah I was having the same issue. Turns out, HDMI2 port on the monitor doesn't do 60Hz. Try HDMI1 port. It should work. I spent 30 minutes plugging and unplugging. They should prob label that better ngl.

**Q: Why don't you seperate q&a for each model? amazon qa is a mess.**
A: I don't know I bought this as a gift.

**Q: What frame rates does this support if any (for video)? 29.97? 23.976? 59.94? Thanks!**
A: Note that the Frame Rate is a function of the GPU and that the Refresh Rate is how many times a second Hertz or Hz the monitor is updating the screen image.  If your graphics card is putting out 90 frames per second then the monitor will be dropping 30 of those frames.  The AOC U2790VQ 27" has a maximum refresh rate of 60Hz; if your GPU can deliver more than this, look for a monitor with a refresh rate of 120Hz or more.

**Q: does it work for 120 volt AC? Specs say 240**
A: Yes. I'm running mine on 120.
