Muitas vezes, este não é o caso, especialmente para cartões low-end.
O desempenho da reprodução de vídeo depende muito dos aceleradores de vídeo presentes.
Digamos que você queira comprar uma GeForce 8400 GS barata. Veja as especificações :
NVIDIA® PureVideo™ HD Technology: The combination of high-definition video decode acceleration and post-processing that delivers unprecedented picture clarity, smooth video, accurate color, and precise image scaling for movies and video. Feature requires supported video software. Features may vary by product.
Discrete, Programmable Video Processor: NVIDIA PureVideo is a discrete programmable processing core in NVIDIA GPUs that provides superb picture quality and ultra-smooth movies with low CPU utilization and power.
Hardware Decode Acceleration: Provides ultra-smooth playback of H.264, VC-1, WMV and MPEG-2 HD and SD movies.
HDCP Capable: Designed to meet the output protection management (HDCP) and security specifications of the Blu-ray Disc and HD DVD formats, allowing the playback of encrypted movie content on PCs when connected to HDCP-compliant displays. Requires other HDCP-compatible components.
Spatial-Temporal De-Interlacing: Sharpens HD and standard definition interlaced content on progressive displays, delivering a crisp, clear picture that rivals high-end home-theater systems.
High-Quality Scaling: Enlarges lower resolution movies and videos to HDTV resolutions, up to 1080i, while maintaining a clear, clean image. Also provides downscaling of videos, including high-definition, while preserving image detail.
Inverse Telecine (3:2 & 2:2 Pulldown Correction): Recovers original film images from films-converted-to-video, providing more accurate movie playback and superior picture quality.
Bad Edit Correction: When videos are edited after they have been converted from 24 to 25 or 30 frames, the edits can disrupt the normal 3:2 or 2:2 pulldown cadence. PureVideo uses advanced processing techniques to detect poor edits, recover the original content, and display perfect picture detail frame after frame for smooth, natural looking video.
Noise Reduction: Improves movie image quality by removing unwanted artifacts.
Edge Enhancement: Sharpens movie images by providing higher contrast around lines and objects.
Esta placa pode suportar resoluções mais altas, mas só pode reproduzir vídeos dos formatos posteriores (que cobrem a maioria dos que você deseja) em 1080p.
