31.5″ 4K all-in-one for home and office

The HP OmniStudio X combines a 31.5-inch IPS 4K display with an 8-core Intel Core Ultra 7-256V processor, 16 GB of onboard LPDDR5X memory and a 4 TB PCIe NVMe SSD. Windows 11 Home is pre-installed. Integrated Intel Arc 140V graphics drive the 60 Hz panel. Wi-Fi 6E and Bluetooth 5.4 handle wireless connectivity.

Soldered 16 GB LPDDR5X cannot be upgraded

Memory is fixed on the motherboard, so the 16 GB capacity is permanent. Buyers who need more RAM for virtual machines, heavy rendering or large datasets should choose a different system. The 4 TB NVMe SSD provides ample storage, but only the single internal slot is available for expansion.

No internal access required for daily use

The all-in-one chassis arrives assembled with wireless keyboard and mouse included. Setup is limited to plugging in the 280 W power supply and attaching any USB or HDMI 2.1 peripherals. Opening the unit voids the Velztorm upgrade warranty and risks damaging the integrated display assembly.

Questions about this item

What does the 4.8 GHz boost clock on the Ultra 7-256V mean for everyday workloads?

The processor can reach 4.8 GHz on its performance cores for short bursts, speeding up single-threaded tasks like app launches and web browsing before returning to the 2.20 GHz base frequency.

What display outputs does the HDMI 2.1 port actually support on this all-in-one?

The HDMI 2.1 port can drive an external monitor at up to 4K resolution and 60 Hz, matching the built-in 31.5 inch 3840x2160 60 Hz panel.

How much desk depth does the 28.15 inch deep chassis require?

The unit measures 28.15 inches front-to-back, so allow at least that depth plus a few inches for cable clearance behind the stand.
