The decision

M28U offers a higher-resolution workspace and a high-refresh PC option in one monitor. That combination is useful if both jobs matter to you, but it also makes the GPU, cable and input mode part of the decision. Do not equate the HDMI 2.1 label with unrestricted support for every 4K format.

Consider it when

  • A 4K desktop whose GPU supports the required connection mode.
  • A multi-computer arrangement that can use the KVM with proper USB upstream cabling.

Look again when

  • Expecting a console to use the PC’s 144 Hz mode.
  • A GPU or cable path that cannot support the required compression and timing.

The checks that can change your choice

Check DSC for the desired HDMI mode

GIGABYTE specifies DSC for 4K 144 Hz 4:4:4 over HDMI, with console support up to 120 Hz. Verify the source, cable and colour format together before promising that configuration.

Map the KVM connections

Video and USB are separate parts of switching a keyboard and mouse. Connect the necessary upstream paths and test the desired PC-to-laptop changeover; a second video cable alone does not complete the KVM setup.

Published specifications

28-inch IPS; 3840 × 2160; up to 144 Hz; DisplayPort 1.4, HDMI 2.1 and USB-C.

A different choice worth checking

ASUS ProArt Display PA279CVPA279CV is a useful shortlist entry when text, layout and a 4K workspace matter more than a high-refresh gaming mode. The USB-C display and charging path can reduce cabling, provided the laptop supports the correct video mode and is comfortable with 65 W power delivery. The ProArt label does not remove the need to manage colour for your actual workflow.Read this model’s tradeoffs ↗ASUS ROG Swift OLED PG32UCDMPG32UCDM is a deliberate choice for someone who wants a 31.5-inch 4K OLED workspace and a high-refresh gaming mode on the same desk. Check viewing distance and GPU output before selecting it. The 240 Hz limit describes a supported display mode, not the frame rate a game will achieve at 4K.Read this model’s tradeoffs ↗
