opengl for intel g45 g43 express chipset

The GMA X4500 lacks the “HD” designation of the core that’s packed into the Intel G45 Express northbridge, but it still offers Intel Clear Video technology, for post-processing of video playback to reduce jitter, smooth edges, and improve brightness and color saturation. It’s still got a DX10-capable Intel GMA X4500 integrated graphics core, however, which is important for another reason – Intel’s low-end integrated-graphics chipsets have typically represented the low-end baseline for the entire integrated-graphics product category. While Intel’s G45 Express chipset represents a higher-end integrated-graphics product, with its HD video processing and enhancement features, the G43 Express is an enterprise-class part (a kind way of saying ‘low-end’) that omits the HD video processing entirely. This places the X4500HD on more even footing with AMD’s 780G and 790GX IGP chipsets and Intel’s new GeForce 8300 “Motherboard GPU” when it comes to suitability for home theater PC use. In addition, Intel has brought their Clear Video Technology to bear on the GMA X4500HD to provide post-processing functionality that improves color saturation and accuracy, and eliminates artifacts in playback. The GMA X4500HD offers similar hardware HD processing, accelerating H.264 playback at 1080p resolution.

AMD has had their AVIVO HD with UVD for some time now, and NVIDIA has had PureVideo HD. The GMA X4500HD video processor also brings Intel’s integrated-graphics offerings up to speed with the competition when it comes to hardware acceleration of HD video playback. HDCP compliance is pretty much a given at this point on any hardware that features an HDMI connector, and the GMA X4500HD also supports the integration of an HDMI video output. That means that your PC’s graphics adapter will need to be HDCP-compliant in order to play back hi-def media at its full resolution, instead of a scaled-down standard-definition resolution.

HDCP requires digital handshaking at every stage in the signal chain, starting at the player itself. High-Definition Content Protection, known around here as simply ‘HDCP’, is a content protection scheme used by modern hi-def formats like the late HD-DVD and the victorious Blu-Ray format. The Intel GMA X4500HD video processor incorporates a trio of features that will be of importance to home theater and media center PC builders, one of them an absolute necessity if you’re planning on playing back any Blu-Ray discs anytime soon: HDCP compliance.
