Comment Why was it choosen (Score 1) 55

I get the fact that there was huge malfunction in the system that was supposed to limit each donor to less than 10 people.

I get the fact that there were inadequate/mistakes screenings.

But the real question is what description led it to be chosen over 200 times by the customers?

Hypothesis: Tall, handsome, doctor.
Null hypothesis: Kind, loving, honorable

Anyone willing to bet on the null?

Comment Re:Can't Europe (Score 1) 116

The time has come for a European University CSE department group to reverse-engineer HDMI 2.1 and publish a compatible implementation on Github.

There's a solid history of this category of work going back 30 years.

They have certain legal protections for compatibility and public interest work.

This 1990's licensing model is antiquated and obsolete.

IEEE and ITU have abdicated their responsibility so sombody like Valve needs to do for transport spec what AV1 did for codecs and linux did for operating systems.

"A rising tide lifts all boats" is common among free marketeers and communists but opposed by fascists.

> Is there a huge difference between a criminal organization and a multinational corporation?

Yes, huge difference.

The common-law criminals running corporations get statutory protection from liability for the crimes they commit under corporate letterhead.

A regular mafia has individual liability.

Comment Cheap (Score 2) 116

However I suspect it would be a bit more than $10 today.

A bit, but not much. (random example off AliExpress, that use this synaptic chip)

Worse yet, such a setup would most certainly add latency to an application, gaming, that is sensitive already to any delays. Gaming is what drives the 120Hz and above refresh rates...

There's no real reason why latency should be more than a couple of "scan-lines" (well, at least the DSC's equivalent horizontal-lines, if the signal needs conversion between compression variants). And there's a big incentive: less on-chip built-in RAM - it's litteraly cheaper to make the chip only keep the most recent relevant data and immediately start streaming out the HDMI 2.1 signal as soon as possible, rather than keeping multiple entire frames.

Comment Dongles (Score 1) 116

I fear that most DisplayPort to HDMI 2.1 dongles are not active adapters but instead passive physical connection switches.

Most, but not all. I litterally have a DisplayProt to HDMI + DVI + VGA combo dongle on my workstation at home.

But they tend to by a tiny bit more expensive (think 10 bucks instead of 1 bucks on AliExpress. Or 50 bucks at your local TV shop), because they require a dedicated chip inside the dongle.

Although to my frustration it has never worked the other way around with a HDMI ports being simply physical convertible to a DisplayPort.

Depends on the device. Can happen in some professional projectors: some enterprise-grade projectors can litteraly support "any protocol over any wiring with enough pins", i.e.: the presence of a HDMI, DP, DVI or VGA connector on a given port is mainly a convenience. This is so you could reuse wathever cabling is embed in the walls, you don't need to tear down the walls and redo the cabling (which could get expensive in a large conference room). This is also the reason you could find ultra cheap passive VGA-to-HDMI cables on AliExpress/eBay/Amazon for the last segment between the VGA port built into the lectern of some old university lecture room and the laptop outputting the HDMI that the projector is actually configured to fetch from the VGA cabling embed in the walls.

Comment SteamDeck (Score 1) 116

You can use DisplayPort instead. Is it possible to convert DP to HDMI 2.1?

Yes, that's litteraly how the SteamDeck handles this.
The SteamDeck can output DisplayPort on its USB-C connector (similar to tons of laptops and some smartphones), and the SeamDeck's Dock has a dedicated hardware chip that does the translation into HDMI signal.
This way no need to tweak any support into opensource GPL'd drivers inside the SteamDeck and then risking running afoul of HDMI's licensing restrictions.
