Date published: 2025-08-20
Rated 4 out of 5 by from Great monitor for a sensible price. I am really pleased with my new HP Omen 32 inch curved monitor. It was simple to set up and the image quality is very good straight out of the box. The stand is solid and the height adjusting mechanism is smooth and secure.

Rated 5 out of 5 by from Not just for Gaming I’m an accountant and it makes numbers easier to read and is a great size alternative to dual monitors
Date published: 2023-12-09
Rated 5 out of 5 by from Great Color and Performance I love the size and the 165 MHz refresh rate is wonderful. The color out of the box using standard mode is great. It also upscales 1080p wonderfully. I think it's a wonderful monitor.

Rated 5 out of 5 by from Wonderful monitor Wonderful monitor. Well worth the extra money for 31 inches as opposed to 27 inches.

Rated 4 out of 5 by from Beautiful monitor with a minor operating quirk Very happy with new monitor now that I have learned one of its quirks. Unpacking and setup were easy. Monitor performance is as expected - very large and clear. However, monitor has one quirk. When I used my HP desktop and prior HP monitor, I would turn on the surge protector and both the units would be powered. I would then press the button on the desktop to turn it on and the monitor (which was always switched on, waiting for power) would see the signal from the desktop, recognize the computer signal and I could go to work. I assumed the OMEN would work the same way. After I replaced my old HP monitor with the OMEN and turned on the surge protector, the monitor powered up, displayed a large blue block consisting of 4 smaller blue blocks and froze. When I turned on the desktop, the OMEN monitor did not recognize the computer signal. I now do the following: At the end of any work session, I turn off the OMEN using the switch on the back of the unit after shutting down the desktop. The next time I want to use the system, I turn on the power at the surge protector, turn on the desktop and then turn on the OMEN using the switch on the back of the unit. The monitor then "sees" the desktop signal and functions normally. If you have any idea why this is happening, please let me know as I don't believe that this is normal behavior.
