The city of Las Vegas late last year added another attraction to its town: the Sphere. The Sphere is a 1.2 million pixel outdoor display venue famous for its massive size and inner 18,600-seat auditorium. The auditorium space is a feat of its own with features like a 16x16 resolution wraparound interior LED screen, speakers with beamforming and wave field synthesis technologies, and 4D physical effects. However, we have recently found out that NVIDIA GPUs power the Sphere. And not only a handful of them, as 150 NVIDIA RTX A6000 power the Sphere and its 1.2 million outside pixels spread on 54,000 m², as well as 16 of 16K inner displays with a total output of 2.1 billion pixels. Interestingly, the 150 NVIDIA RTX A6000 have a combined output cable number of 600 DisplayPort 1.4a ports.

With each card having 48 GB of memory, that equals to 7.2 TB of GDDR6 ECC memory in the total system. With the Sphere being a $2.3 billion project, it is expected to have an infotainment system capable of driving the massive venue. And it certainly delivers on that. Only a handful of cards powers most massive media projects, but this scale is something we see for the first time in non-AI processing systems. The only scale we are used to today is massive thousand-GPU clusters used for AI processing, so seeing a different and interesting application is refreshing.

Renowned HDTVTest YouTube reviewer and presenter, Vincent Teoh, has been exploring the showroom floor at this year's Display Week trade symposium (in Los Angeles, CA). He was intrigued by some cutting-edge screen tech at BOE's booth and announced this discovery on Twitter yesterday evening: "Forget 8K. Here's the world's first 110-inch 16K display unveiled by BOE at Display Week 2023. LCD-based, max 400 nits. The resolution is unreal though, no visible pixels even right up close."

The demo unit appears to be a prototype - BOE Displays has not revealed any type of official product launch. Their giant screen is reported to be almost 2.8 meters wide in terms of diagonal length, and a specification sheet placed nearby lists a maximum 15360x8640 resolution paired with a 60 Hz refresh rate. The 16K display has a contrast ratio of 1200:1 and is capable of reproducing 99% DCI-P3 color coverage. We hope to view further reports from this tradeshow - hopefully a BOE rep will provide details about the required GPU power to run their monster LCD monitor.

AMD's upcoming Radeon RX 7000 series of graphics cards based on the RDNA 3 architecture are supposed to feature next-generation protocols all over the board. Today, according to a patch committed to the Linux kernel, we have information about display output choices AMD will present to consumers in the upcoming products. According to a Twitter user @Kepler_L2, who discovered this patch, we know that AMD will bundle DisplayPort 2.0 technology with UHBR 20 transmission mode. The UHBR 20 standard can provide a maximum of 80 Gbps bi-directional bandwidth, representing the highest bandwidth in a display output connector currently available. With this technology, a sample RDNA 3 GPU could display 16K resolution with Display Stream Compression, 10K without compression, or two 8K HDR screens running at 120 Hz refresh rate. All of this will be handled by Display Controller Next (DCN) engine for media.

The availability of DisplayPort 2.0 capable monitors is a story of its own. VESA noted that they should come at the end of 2021; however, they got delayed due to the lack of devices supporting this output. Having AMD's RDNA 3 cards as the newest product to support these monitors, we would likely see the market adapt to demand and few available products as the transition to the latest standard is in the process.

DisplayPort 2.0 was supposed to see its implementation beginning by the end of 2020, but that time has come and gone without a single DisplayPort 2.0-touting product on sight. According to VESA, the rollout has been delayed mostly due to the COVID-19 pandemic, which prevented the standards body to perform its PlugTest events, where engineers and hardware developers convene to discuss, tinker, and decide on the standard's implementation. VESA held multiple of these events per year, but none in 2020, due to the COVID-19 pandemic; thus, the delay we are now witnessing surged.

VESA plans to have their first 2021 PlugTest event in Spring of this year, however, and aims to see products on the shelves later, and likely not before 2H 2020. The standards body said that there are, indeed, DisplayPort 2.0 monitors currently in-development, but that these too have been affected by the lack of PlugTests. DisplayPort 2.0 is an update to the current 1.4 implementation, and currently, there are no launched products (monitors, graphics cards, etc) that can make use of the new version. The new standard will technically support up to 80 Gbps max, nearly three times the currently available bandwidth in the DisplayPort 1.4 spec. DisplayPort Alt Mode 2.0 also brings most of these capabilities to USB Type-C connectors via the USB 4.0 revision.
