All-in-One PC with 31.5" 4K IPS Display

The HP OmniStudio X integrates a 31.5-inch IPS panel at 3840 by 2160 resolution and 60 Hz refresh into a single Meteor Silver chassis. It targets home-office workers and creative hobbyists who want a clutter-free desk without a separate tower and monitor. The system ships with Windows 11 Home, a wireless keyboard and mouse, and a bundled Dockztorm USB hub rated for 5 Gbps data. Buyers who need internal expansion slots or user-replaceable memory should look elsewhere.

280 W Power Supply and Integrated Arc 140V Graphics

A 280 W internal supply feeds the 8-core Ultra 7-256V processor with 12 MB cache and the Arc 140V integrated GPU. The CPU runs at a 2.20 GHz base and can reach 4.8 GHz on its four performance cores. With graphics built into the SoC there is no discrete card to add heat or fan noise, so the all-in-one stays quiet during typical productivity, streaming and light creative workloads. The LPDDR5X memory is soldered down, limiting future upgrades.

HDMI 2.1, Dual USB-C and Wired Ethernet

Rear I/O includes one HDMI 2.1 port, one USB 3.1 Type-C port and one USB 3.2 Type-C port plus a headphone/microphone combo jack. An RJ-45 jack provides wired networking alongside Wi-Fi 6E MT7922 and Bluetooth 5.4. The fixed 22.25 by 28.15 by 7.8 inch footprint and 21 lb weight mean the unit sits securely on a desk but cannot be VESA-mounted or moved frequently. The included USB hub adds extra Type-A ports for legacy peripherals.

Questions about this item

How do I connect the included DKZ USB hub and what port should I use?

Plug the DKZ hub into the USB 3.1 Type-C or USB 3.2 Type-C port; it supports up to 5Gbps data rate.

Will the 16GB LPDDR5X memory need upgrading later?

The 16GB LPDDR5X is onboard and not user-replaceable; no memory upgrades are possible.

At what temperature does the 280W power supply throttle the Intel Ultra 7-256V under sustained load?

The 280W PSU and integrated Arc 140V graphics share thermal limits; sustained 4.8GHz boosts will throttle first when the chassis hits its thermal ceiling.
