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. Now you’ll be able to play Civ5 again.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. Here is a screenshot of the driver version that works correctly for me: You’ll be prompted with the following message indicating that you are about to downgrade the display driver. Unzip the driver to your desktop and double click the setup.exe program file.
Intel G43/G45 Chipset & Display Drivers v. Download the Intel Chipset Driver version 8. The problem: All-in-one systems like the Acer Z5600 with the updated drivers (version 8.) for the Intel G43/45 Chipset exhibit the following behavior (see video) at all resolutions except 1920×1080. All full screen games that operate at lower resolution ceased to function including Civ5. Since the update it has been impossible to scale the display resolution to anything but the native/optimal 1920×1080. Then in August 2010 an important Windows update for systems with the Intel G43/G45 Chipset broke my display driver. I bought an Acer Z5600 year ago and it’s been working pretty well for playing games and browsing the web.
