Connectors from Graphics Cards to Monitors – can Monitors adjust hz?

Hi all,

can any PC geeks out there tell me what I’m looking for in a monitor? I’ll be building a computer around a RTX 3080 card that has Display Port 1.4 (*3) and HDRMI 2.1.

The goal is a maybe 32inch 4k UDH Monitor that actually runs at higher than 60hz? Say a 120hz or 144hz would be acceptable – they seem to be the speed increments out there (although I’ve only started looking.)

But according to the chart below the Display Port 1.4 connector would limit a 4k screen to 120hz. Would a 144hz monitor be able to downsize/downscale/adjust to 120hz? Anyone know?

This site says yes it can but it uses DSC – Display Stream Compression – but I’ve no idea how seriously that impacts on performance.

DisplayPort 1.2 can output 1080p and 1440p resolutions at 144Hz, while DisplayPort 1.3 and 1.4 increased bandwidth to manage up to 240Hz at those same resolutions and up to 120Hz at 4K. It can’t quite handle 144Hz at that resolution, at least without making sacrifices in chroma subsampling (typically 4:2:2) or using display stream compression (DSC).
