Why Vesa's new Displayport DP54 cables are almost without alternative and the future of active cables

[Redaktion]

The Vesa has long had a distance problem: particularly high bandwidths are difficult to achieve from a tower under the desk to a monitor. This has now been solved with a new certification. Notebookcheck.com spoke to Vesa at CES about DP54 cables and new active cables.

Oh great... New types of type-c cables. Just look for the easy to understand markings of DP40/DP54/DP80.

As I have been writing for several years now, these fools, instead of switching to optical cables, continue to stupidly try to get out with copper cables, which can no longer be used due to the lack of the ability to produce quality-controlled 2-3 m cables (and are needed for 10-50 m ).

How much longer will the consortium continue to jerk off to copper? When will they introduce optical cables in the same braid with copper ones for the supply wires? What the hell is so hard about it in 2024?!

And the masses will have to learn to carefully handle optical connectors and cables, because only they are the real future. But they will have to otherwise lose money.

Projector owners have long needed 15-50m cables, and eGPU owners could move external discrete cards away from themselves in the utility room (along with a laptop or even a system unit).

Only a hub for peripherals should remain on the table, connected to the system unit/laptop via an optical cable with a bandwidth of at least 500 Gbit/s, or better yet 1 Tbit/s. To do this, 2-3 optical cores in the cable are enough.

Greedy producers are trying to deliberately delay the future for humanity, for the sake of mercantile personal interests. Turning human progress into a farce. Capitalism, in its unbridled pursuit of profit, must be strictly limited by government best standards, which must be forcefully imposed on large corporations for the sake of human progress.

The entire industry and the VESA consortium simply publicly disgraced themselves in front of all the experts. First, they came up with the Display Port 2.0 (80Gbit/s) standard back in 2019, and now, even almost 5 years later, they cannot create working equipment in the mass segment that fully implements this standard! Is it possible to disgrace the hardware industry even more than with the introduction of Display Port 2.0 equipment (in UHBR20 mode) into the mass segment? It is precisely because of the lack of mass-market video cards and video chips built into the SoC with support for DP2.0+UHBR20 that there are still no beautiful 8K monitors on sale with close to ideal ppi for human eyes!

Damn it, it's time to switch the world to optics! Forget about copper cables!

And the most shameful thing is that even Display Port 2.0-2.1 are already obsolete, never appearing in mass-produced equipment! After all, for a smooth picture for the eyes, even when scrolling text on 8k monitors, you need a frame rate of at least 120Hz (and naturally the panel response is no more than 7-8 ms on G2G/B2W)! And 8k@120Hz requires at least 160Gbps cables, for lossless modes in at least 30-bit color!

Does anyone believe that cheap 160Gbit/s copper cables over 2-5m are possible in practice? Again he goes only to optics.
