All-in-One Desktop with 27-Inch Touch Display

The HP OmniStudio 27 combines the processor, memory and storage behind a 27-inch FHD IPS touchscreen. An Intel Core Ultra 7 355 with Intel AI Boost delivers 8 cores and up to 4.7 GHz. The system ships with 64 GB DDR5 RAM, a 1 TB SSD and Windows 11 Home. It is aimed at home offices and creative users who want a tidy, single-unit workstation.

Simple Setup with Wireless Peripherals

The unit arrives assembled; only the 90 W power adapter and the included wireless keyboard and mouse need connecting. No internal hardware access is required for normal use. The sealed chassis means memory or storage upgrades are not user-serviceable, so buyers must accept the factory configuration. Cable management is limited to the rear I/O panel.

Suits Space-Conscious Workflows.

Buyers who value a clutter-free desk with touch input, a 1080p IR camera and Wi-Fi 6 connectivity will appreciate the integration. Users who need discrete graphics, additional drive bays, PCIe slots or the ability to replace the display separately should consider a traditional tower and monitor combination.

Questions about this item

How can I confirm the 27" 1920 x 1080 75 Hz touch IPS display is performing correctly after setup?

Open Display Settings in Windows 11 Home and verify the resolution reads 1920 x 1080, the refresh rate is set to 75 Hz, and HDR is available; then test touch response across the full 27" panel and check that the anti-glare coating reduces reflections under bright light.

The box contains the HP OmniStudio 27 All-in-One, a 90 W 4.5 mm AC power adapter, an HP 275C USB wireless keyboard and mouse combo, and documentation; no additional cables or peripherals are required for basic operation.

Which configuration should I choose if I need the 49 NPU TOPS AI Boost and 64 GB DDR5 memory?

Select the model listed with Intel Core Ultra 7 355, 64 GB DDR5 RAM, 1 TB SSD, Windows 11 Home, and the 27" FHD touch IPS display — this exact specification delivers the 49 NPU TOPS AI Boost and the full 64 GB DDR5 capacity.
