Galaxy Book4 Ultra 16" AMOLED Touch

The Samsung Galaxy Book4 Ultra is a 16-inch laptop built around an Intel Core Ultra 9 185H processor and an NVIDIA GeForce RTX 4070 GPU.

The chassis provides two Thunderbolt 4 connectors and one HDMI 2.1 output for driving external monitors or high-speed peripherals. A single USB-A 3.2 port remains for legacy devices. The AMOLED touch panel supports pen and finger input directly on the 2880 x 1800 screen.

The 16-inch AMOLED display runs at a 120Hz refresh rate with a peak brightness of 400 nits, delivering smooth motion and strong contrast for colour-critical work. The RTX 4070 discrete GPU handles render workloads while the Intel Core Ultra 9 185H manages compute tasks. A 1000 gigabyte NVMe SSD stores the operating system and project files.

Questions about this item

What does the Thunderbolt 4 interface cap at for external displays on this laptop?

Thunderbolt 4 supports one 8K or two 4K external displays at 60 Hz; the HDMI 2.1 port adds a third 4K display at up to 120 Hz.

What physical slots are required to add storage to the Galaxy Book4 Ultra?

The 1 TB NVMe SSD occupies the single M.2 slot; adding more storage requires replacing that drive because no second M.2 slot is present.

How is the 32 GB LPDDR5X memory installed, and what mistake do buyers make?

The 32 GB LPDDR5X is soldered to the motherboard and cannot be upgraded; buyers often assume a SO-DIMM slot exists and purchase incompatible memory.
