16-inch WQXGA 144 Hz display

The LG Gram Pro 16Z90TR-E.AZB8U1 is a 16-inch laptop with a WQXGA IPS panel running at 144 Hz. It pairs an Intel Core Ultra 9 285H processor with 32 GB of memory and a 1 TB SSD. An NVIDIA RTX 5050 GPU with 8 GB GDDR7 handles graphics workloads. Windows 11 Pro is pre-installed.

Creators needing colour accuracy and GPU power

The 99 % sRGB coverage and 400 nit brightness suit photo and video editing, while the dedicated RTX 5050 accelerates rendering and 3D tasks. Buyers who want more storage or a higher-wattage graphics solution should look elsewhere.

Intel Core Ultra 9 285H with 5.40 GHz turbo

The processor reaches a 5.40 GHz turbo frequency across its performance cores, defining the ceiling for single-thread speed in this chassis. That figure determines whether the system meets your compile, simulation or real-time playback targets.

Questions about this item

Should I pick the 32 GB / 1 TB configuration or look for a different capacity?

The model is offered with 32 GB of memory and a 1 TB SSD. Memory is soldered and not upgradeable, so choose this version if 32 GB covers your workload; otherwise you would need a different SKU.

What does the 5.40 GHz turbo frequency mean for everyday performance?

The Core Ultra 9 285H can boost to 5.40 GHz on demanding threads, giving short bursts of high speed for compile jobs or heavy spreadsheets, while sustained clocks will sit lower depending on cooling.

How does Wi-Fi 7 affect real-world wireless speed?

Wi-Fi 7 uses wider channels and multi-link operation, so peak throughput and latency improve over earlier standards when paired with a compatible router.
