All-in-One desktop with touch display

The HP OmniStudio All-in-One combines a 27-inch FHD touchscreen with an Intel Core Ultra 7 355 processor, 16 GB DDR5 memory and a 512 GB SSD. Windows 11 Pro is pre-installed alongside a wireless keyboard and mouse. The system targets home and office users who want a compact, cable-reduced workstation with AI-ready performance. Integrated Intel Graphics handle everyday visual tasks without a discrete card.

Thermals noise and power in daily use

A 90 W AC adapter powers the entire unit, so typical draw stays well within that envelope during office workloads and media playback. The all-in-one chassis uses internal airflow rather than exposed fans, keeping acoustic output low in quiet rooms. Touch-panel operation adds no audible noise, and the Low Blue Light mode reduces eye strain during long sessions.

Upgrade path and when the jump matters

Buyers moving from an older non-touch all-in-one or a traditional tower plus separate monitor gain a unified 27-inch 1920 x 1080 IPS panel with 350 nits brightness and 100 % sRGB coverage. The DDR5 platform supports up to 64 GB and the M.2 slot accepts up to 2 TB NVMe storage for future expansion. Users who need discrete graphics performance, multiple high-refresh displays or a smaller footprint should consider other form factors.

Questions about this item

How do I set up the 27" touch all-in-one and which step do people often miss?

Connect the 90 W 4.5 mm AC adapter, press the power button, then pair the HP 275C wireless keyboard and mouse via their USB receiver; the step many skip is inserting two AAA batteries into each peripheral before pairing.

Which components can I upgrade later and what are the limits?

The board supports up to 64 GB DDR5 RAM and up to 2 TB PCIe NVMe M.2 SSD; the 16 GB DDR5 and 512 GB SSD installed today can both be replaced when you need more capacity.

What thermal or power limit appears first during long heavy workloads?

The 90 W AC adapter caps total system draw, so sustained all-core loads at 4.7 GHz Turbo will hit the power brick limit before the Intel Core Ultra 7 355 reaches its thermal ceiling.
