Love this monitor.
Cord holder snapped in half before I even got it upright but that's the only downside. This is the second one of these monitors I've purchased and I love both of them.

Great Monitor
I have this HP OMEN 27qs G2 Cloud running with a 5070 Ti PNY video card. The two together are just simply amazing. Thanks HP!

Better than I thought it would be.
Great monitor, I purchased this specifically for the KVM function (it's hardware KVM and no software needs to be installed for it to work) the KVM Functions perfectly. I was very impressed with the quality of the display, beautiful picture, crips clear text. The backlighting can be turned on or off, and can be set to different modes - I'm not a gamer, but the display is very responsive for everything that I've used it for. I also really appreciate the fact that there is NO POWER BRICK! it's a standard AC cord that plugs directly into the monitor. There are plenty of ports, and the stand feels sturdy. I don't reqret the purchase at all and would not hesitate to recommend the display to anyone looking for a 4K display.

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.
