About
A 28" 4K 144Hz monitor with an integrated hardware KVM switch — its two HDMI 2.1 ports are physically bottlenecked below the full FRL spec, requiring DSC compression to sustain 4K144 at full chroma.

- Notebook (generic)
Both HDMI 2.1 ports are physically limited to 24Gbps rather than the full 48Gbps FRL bandwidth of the spec — hitting 4K@144Hz at 10-bit 4:4:4 chroma over HDMI requires the source GPU to apply DSC compression. Sources without DSC support must drop resolution, refresh rate, or chroma subsampling to compensate.
