Dont know. No computer yet!
Who knows if they're great or not? I've been nothing but disappointed with HP since I ordered 2 of these and a gaming computer. The address was wrong and my monitors were delayed by multiple days, arrived wet, the box is damaged, and one of the boxes sliced open. I reached out to HP to correct the address issue, since the computer hadn't gone out yet, THREE TIMES and it was still shipped to the wrong address. This after multiple delays cause the computer to be shipped. well after the holidays. I was assured every time I called that although the address looked wrong on my end, they had it right. They didn't. The gaslighting about it, after spending $2,000 really, really irks me. I still don't have my son's gaming computer; the monitors got here 3 weeks ago. It's January 2nd, this was a Christmas present. If the computer was just late, because of global memory shortages, I get that. But to have all this extra time and multiple calls and still send it out incorrectly is unacceptable.

Amazing with 1 minor issue.
Love the monitor. My ONLY issue was that mine has one tiny pixel you can see in the middle of the screen. Only on the darker backgrounds. Its hardly noticeable on anything else. Im still very happy with the purchase, 1440p is amazing!

Good product, confusing setup
I had issues getting it set up. It wasn't crystal clear which cords went where, and them being just the tiniest bit loose meant the monitor didn't turn on which made me think I'd hooked it up wrong. But once it was hooked up properly it worked really well.

the DisplayPort cable included... does it support DP alt mode?
Thank you for your question! This Omen HP display comes with a DisplayPort cable. This is not a USB-C cable that is included but a DisplayPort cable. DisplayPort Alt Mode (DP Alt Mode) is a feature that allows USB-C ports to transmit video and audio signals, including high-resolution video output up to 8K. This is possible by remapping the USB-C high-speed data pins from USB data to DisplayPort data. DP Alt Mode allows a USB-C-equipped computer to connect directly to a display or monitor that has a USB-C port.
