The latest DisplayPort V1.4 HBR3 8K monitors are trickling onto the market with DELL being the first to show off its latest UltraSharp 32 model. FuturePlus took a look under the hood by snooping all of the traffic on the 8.1Gb/s high speed main link and the Aux Port. The DELL monitor performed as advertised training at HBR3 speeds and correctly sending frame data at that speed.

The MSA (Main Stream Attribute Packet) shows the screen dimensions and coloremitry.

And now for the pixels! The large trace buffer of the FS4500 DisplayPort Protocol Analyzer is needed to store the large 8K frames.

All in all the DELL monitor looked good! Got a DisplayPort project that could use an analysis tool? Check out our datasheet! Want a demo? Contact us.
