How this entity was disambiguated

This entity first appeared as the object of triple T2447580 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Display Stream Compression
Context triple: [DisplayPort, supports, Display Stream Compression]

A. TransformStream
TransformStream is a web streams API interface that enables transforming data chunks passing through a readable–writable stream pair, such as for compression, encryption, or format conversion in streaming workflows.
B. H.264
H.264 is a widely used video compression standard known for delivering high-quality video at relatively low bitrates, commonly employed in streaming, broadcasting, and video recording.
C. NVIDIA Image Scaling
NVIDIA Image Scaling is a driver-based spatial upscaling and sharpening feature from NVIDIA that boosts game performance and clarity by rendering at lower resolutions and scaling images in real time.
D. H.265
H.265, also known as High Efficiency Video Coding (HEVC), is a video compression standard designed to significantly reduce bandwidth and storage requirements compared to its predecessor H.264 while maintaining high visual quality.
E. MPEG
MPEG is a family of widely used digital audio and video compression standards developed by the Moving Picture Experts Group for efficient storage and transmission of multimedia content.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
