WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

MSI G321CU

What it brings

Provides 4K at up to 144 Hz and USB-C display input. HDMI requires the 4K 144Hz – PC setting for its maximum mode.
Manufacturer source Manufacturer source
PIP/PBP can show multiple inputs, and the 1500R VA panel has 3000:1 contrast and 114% sRGB (CIE 1976).
Manufacturer source Manufacturer source

What to check

MPRT Sync disables USB-C charging. PIP/PBP disables FreeSync Premium and MPRT Sync; these features are not all available together.
Manufacturer source
MSI's documents give different DisplayPort revisions (1.4a and 1.4b), and its overview and manual disagree on USB-C data transfer, so do not count on USB-C for data.
Manufacturer source Manufacturer source Manufacturer source Manufacturer source
The 1 ms figure is MPRT; the grey-to-grey rating is 4 ms. MSI does not list height, swivel or pivot adjustment for the stand.
Manufacturer source Manufacturer source

AOC U32G4U

What it brings

The 3840 × 2160 panel supports a listed 160 Hz native-resolution mode. Check the input-specific conditions alongside the figures.
Manufacturer source
The supplied stand has a listed 130 mm height adjustment, allowing its position to change without adding a separate mount.
Manufacturer source

What to check

The headline maximum spans different resolution modes: UHD 3840 × 2160 at 160 Hz / FHD 1920 × 1080 at 320 Hz (Dual Frame Mode). The faster lower-resolution mode does not deliver the same pixel detail as the native panel mode.
Manufacturer source
Allow for the 269.6 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.
