34-inch 100 Hz UWQHD curved gaming monitor
The HP P34hc G4 uses a 34-inch VA panel with a 1500R curvature and a 21:9 aspect ratio. Its 3440 x 1440 resolution and 100 Hz refresh rate suit gaming and productivity workloads.

Check GPU outputs and desk space before ordering
Verify your graphics card provides DisplayPort, HDMI or USB-C with DisplayPort Alt Mode to drive 3440 x 1440 at 100 Hz. Confirm the 1500R curve fits your viewing distance and that the stand’s height, tilt and slide adjustments suit your eye level. The monitor includes DisplayPort, HDMI and USB-C to USB-C cables in the box. Integrated 2 x 3 W speakers handle basic audio without external hardware.
KVM and USB-C 65 W PD simplify a dual-system desk
Connect two computers and switch keyboard, mouse and video through the built-in KVM with Picture by Picture support. The USB-C port delivers up to 65 W power delivery to charge a compatible laptop while transmitting video and data. Height, tilt and slide adjustments let you align the curved screen with secondary displays. The three-sided micro-edge design reduces visual gaps in multi-monitor configurations.
