    Rated 5 out of 5 by Dragonldy1 from OMEN 27” HP monitor Great color, great size, hdmi cord that came with monitor did not fit into new HP computer. Had to buy different cord. Not crazy about power button on back of screen, needs to be put on front of screen

    Rated 4 out of 5 by Stiggy4k from 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!

    Rated 3 out of 5 by Railun from 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.
