DisplayPort 1.1 Gains VESA Approval

By Geoff Duncan Published April 2, 2007

The Video Electronics Standards Association (VESA) has given its stamp of approval to the DisplayPort 1.1 specification, adding features of special interest to the high-definition video industry as well as the makers of cell phones, portable media players, and other lower-power devices.

DisplayPort is a digital video output standard originally designed for PCs, and is intended to supersede the now-commonplace DVi connector—and maybe even one day do in the time-tested VGA standard. DisplayPort is intended to increase the use of digital outputs on computer displays and other devices in the technology industry, while closing the annoying “analog hole” represented by VGA. DisplayPort is designed to be easier for manufacturers to implement than current standards; consumers, may appreciate DisplayPort’s small USB-sized video connector, higher performance than even dual-link DVI (10.8 Gbps), and a micro-packet architecture to enable new features.

DisplayPort 1.1 adds support for High Bandwidth Digital Content Protection (HDCP) 1.3 (which is of special interest to makers of Blu-ray and HD DVD high-definition video solutions) and the ability to connect to both internal and external displays using a common interface (simplifying the design of mobile phones and other devices which tout multiple LCD displays). DisplayPort 1.1 also provides for low-voltage and low-power operation (again, useful for portable devices) and reduced electromagnetic interference with a new embedded clock architecture.

“The benefits of version 1.1 are significant, and will encourage adoption of DisplayPort in new generations of computers and consumer electronics equipment,” said Bill Lempesis, VESA executive director, in a statement. “Our task groups and committees within VESA worked very hard to ensure that DisplayPort 1.1 satisfies the important objectives it is designed for, and as a result, this new version has widespread support among all the leading computer and consumer electronics suppliers.”

Major DisplayPort supporters include AMD, Intel, HP, Nvidia, Lenovo, Samsung, and Philips.

AI helped uncover a hidden PHP flaw. Now websites worldwide are facing millions of hacking attempts.

A critical PHP vulnerability has websites worldwide racing to install security patches.

PHP is the programming language behind roughly 70% of websites, and it just ran into a serious problem. Security researchers used AI to uncover a critical flaw called PHP2Shell, which could let attackers take over web servers, steal data, or disrupt online services. Since the discovery, websites worldwide have been hit with millions of attempts to exploit it.

Hackers moved fast once the flaw went public. Cloudflare CEO Matthew Prince said the attack attempts jumped from tens of thousands within 45 minutes to millions overnight, The Guardian reports.

Microsoft has begun rolling out Copilot Code for building apps with natural language

The workplace-focused vibe coding tool can pull context from emails, documents, meetings, and chats.

Microsoft introduced Code last month as one of the three core parts of its revamped Copilot app. The app was pitched as an easy-to-use coding agent that lets users describe what they want to build in natural language, like an app, a tracker, a dashboard, an automation, or a workflow, and Copilot would build it for them.

Essentially, it's a workplace-focused vibe-coding app that turns existing work into a functional app, and Microsoft has begun rolling it out through the Frontier program.

AI agents are acting like rogues and causing a huge headache for US banks

US banks block AI agents over fears they could make unauthorised financial moves

Banking

US banks are facing a new kind of digital headache: artificial intelligence agents attempting to access customer accounts and perform actions that may go beyond what users intended. As AI tools become more capable of navigating websites and carrying out tasks independently, financial institutions are scrambling to prevent them from crossing security boundaries.

According to a report published by Axios on October 22, major US banks have detected third-party AI agents operating inside customer accounts without authorisation. Some agents reportedly appeared to attempt actions independently of user instructions. The banks involved have not publicly detailed every incident, and there is no evidence that the reported activity resulted in widespread theft of customer funds.
