HDMI Licensing Group Urges Buyers to Skip Price, Check Cable Certification Labels

HDMI cables are now standardized into three official bandwidth tiers: Premium High Speed (18Gbps), Ultra High Speed (48Gbps) and the new Ultra96 (up to 96Gbps), per rules from the HDMI Licensing Administrator that ban using version numbers alone in marketing. Most 4K streaming only needs the 18Gbps tier, while 4K/120Hz gaming requires Ultra High Speed, and Ultra96 is reserved for extreme formats like uncompressed 4K/240Hz or 8K/60Hz. Buyers are advised to check the certification label and QR code on packaging rather than relying on price or brand name.

Laptops with two USB-C ports ease multi-device charging, report finds

A review highlights how having two USB-C ports on a laptop simplifies connecting peripherals like portable monitors, since one port can handle power while the other manages video and data. The piece notes that laptops with only a single USB-C port force users to rely on multiple adapters and cables—such as HDMI-to-mini-HDMI and USB-A-to-USB-C—to achieve the same functionality, especially when battery life requires the laptop to stay plugged in.

New open-source DRM driver brings full HDMI support to Silicon Motion SM750 card

A developer released sm750hdmifb, an experimental Linux DRM driver specifically for the SE-DP750A-HDMI PCIe card built around the Silicon Motion SM750G10-AC GPU and SiI9024ACNU HDMI transmitter. It enables true 2048-wide output or a scaled 2560x1080 ultrawide desktop with more efficient colour conversion and update handling than the older sm750fb kernel driver it replaces.

Analogue 3D's 4K label refers to output, not native game resolution

Analogue's FPGA-based N64 remake, the Analogue 3D, outputs video at up to 3,840 x 2,160 pixels, but the original games it plays were rendered natively at far lower resolutions, typically around 320 x 240 and occasionally up to 640 x 480. The console upscales and cleans up that old output—removing blur, distance fog, and choppy frame rates—rather than generating new high-resolution textures or geometry.
