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 "tile"). 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" Class 4K UHD IPS LED Monitor with HDR 10 (27" 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

The manual only shows 4K 10-bit as 4:2:2 and 4:2:0. 4:4:4 and RGB only appear under 8-bit. Am I correct in understanding that 10-bit color is only supported for chroma-subsampled formats?

Asked by: MooseBoys
The interpretation for what the manual for the LG 27” Class QHD Nano IPS UltraGear™ Gaming Monitor with G-SYNC™ (27” Diagonal), Model # 27GL850G-B shows is that for 4K @ 60Hz, Chroma Sampling of 4:4:4, 4:2:2, and 4:2:0 is available for a 10-bit Color Depth and that only RGB is available for an 8-bit Color Depth. By comparison, our TVs will support 4K @ 60Hz with Chroma Samplings of 4:4:4, 4:2:2, and 4:2:0 for a 10-bit Color Depth when HDMI Ultra HD Deep Color is set to On and will support 4K @ 60Hz with a Chroma Sampling of 4:2:0 with an 8-Bit Color Depth when it is set to Off...^IFV
