New DisplayPort 1.4 Standard Can Drive 8K Monitors Over A USB Type-C Cable (arstechnica.com)

AmiMoJo writes: VESA has finalized and released the DisplayPort 1.4 spec, which can drive 60Hz 8K displays and supports HDR color modes at 5K and 8K. The physical interface used to carry DisplayPort data -- High Bit Rate 3 (HBR3), which provides 8.1Gbps of bandwidth per lane -- is still the same as it was in DisplayPort 1.3. The new standard drives higher-resolution displays with better color support using Display Stream Compression (DSC), a "visually lossless" form of compression that VESA says "enables up to [a] 3:1 compression ratio." This data compression, among other things, allows DisplayPort 1.4 to drive 60Hz 8K displays and 120Hz 4K displays with HDR "deep color" over both DisplayPort and USB Type-C cables. USB Type-C cables can provide a USB 3.0 data connection, too.

"visually lossless" sounds a lot like lossy...

Call it what it is. Don't break terminology for marketing.

In the medical field this is not meaningless. If a radiologist missed the cancer, and the lawyers find that he was using a "lossy" display there's a real possibility of a lawsuit. This is why diagnostic imaging is almost universally stored in a lossless format. The three main choices being uncompressed, JPEG process-14, or JPEG2000 Lossless.
