Does this use single-stream (SST) or multi-stream transport? I'd like to determine how many I can connect to my Mac. (i.e. 1 MST or 2 SST)

Asked by: JonathanAtJet
Hi JonathanAtJet. In order to achieve 4K resolution at 60Hz, older 4K displays used Multi-Stream Transport (MST), to stitch two halves of a display together into one large surface (aka a &quot;tile&quot;). MST, can carry a signal for two or more monitors on a single cable, allowing for daisy chaining or hub configurations of multiple 4K monitors. More recent displays, like the LG 27&quot; Class 4K UHD IPS LED Monitor with HDR 10 (27&quot; Diagonal), Model # 27UK650-W use Single-Stream Transport (SST), eliminating the need for stitching two halves of a display together in software. Instead, SST monitors feature scalers that support 4K resolution at 60 Hz over a single tile, but it does not support daisy chaining...^IFV
