VESA just announced that, as part of a partnership with the USB 3.0 Promoter Group, the upcoming USB Type-C standard will have the ability to deliver DisplayPort audio and video, with support for resolutions of 4K and higher.

Dubbed “DisplayPort Alt Mode,” VESA says that it will be compatible with adapters that support existing DisplayPort, HDMI, DVI, and VGA-enabled displays. So, once USB Type-C with DisplayPort lands, your current/old monitors and screens won’t get left out in the cold.

When using USB Type C cables and connectors for their DisplayPort feature, you’ll still be able to transmit data through them, VESA says. DisplayPort Alt Mode can transmit data through as little as one or two of the four USB lanes. This frees up the other lanes for data transmission tasks.

So, for example, you could use DisplayPort Alt Mode with a 4K monitor, while also sending data back and forth at speeds as fast as 10GB/s. If DisplayPort Alt Mode uses all four data lanes, it can power 5K monitors while also offering data speeds that are equivalent to USB 2.0.

“DisplayPort has played a vital role in advancing display performance and connectivity for platforms that are increasingly integrated and compact,” VESA exec Craig Wiley says.

On top of all this, USB Type-C will be able to deliver up to 100-watts of power, along with the aforementioned data transfer rates of 10GB/s, which will leave USB 3.0 in the dust.

It’s rumored that the un-announced 12-inch MacBook Air with Retina could include USB Type-C connectors.

Nvidia celebrates Trump, slams Biden for putting AI in jeopardy

The Nvidia RTX 5090 GPU.

In response to new export restrictions placed on AI GPUs, Nvidia posted a scathing blog criticizing the outgoing Biden-Harris administration. The administration's Interim Final Rule on Artificial Intelligence Diffusion largely targets China with restrictions on AI GPUs, according to Newsweek.

Nvidia disagrees. "While cloaked in the guise of an 'anti-China' measure, these rules would do nothing to enhance U.S. security. The new rules would control technology worldwide, including technology that is already widely available in mainstream gaming PCs and consumer hardware. Rather than mitigate any threat, the new Biden rules would only weaken America’s global competitiveness, undermining the innovation that has kept the U.S. ahead," wrote Nvidia's vice president of government of affairs Ned Finkle.

This new DirectX feature could completely change how PC games work

A scene from Fortnite running in Unreal Engine 5.

Microsoft has announced that neural rendering capabilities are coming to DirectX soon. Cooperative vector support, as it's called, will lead to "cross-platform enablement of neural rendering techniques," according to Microsoft, and it will usher in "a new paradigm in 3D graphics programming."

It sounds buzzy, but that's not without reason. This past week, Nvidia announced its new range of RTX 50-series graphics cards, and along with them, it revealed a slate of neural rendering features. Neural shaders, as Nvidia calls them, allow developers to execute small neural networks from shader code, running them on the dedicated AI hardware available on Nvidia, AMD, Intel, and Qualcomm GPUs. Microsoft is saying that it will enable these features on all GPUs, not just those sold by Nvidia, through the DirectX API.
