VGA and Mavericks Question

[DemisesAngel]

Is VGA not supported in just the installation of Mavericks or not supported by the OS as a whole? I ask because my PCIe Graphics Card (ATI 5500) has HDMI, VGA and DVI and I am able to use VGA and DVI (dual monitors) without any issues. Only added the Device ID to the appropriate .plist kext contents.

On an additional unrelated note, where sleep NEVER worked in Mountain Lion, it works perfectly with Mavericks.

Its not supported by the OS when using on CPU graphics (HD3000, HD4000 etc.) but some graphics cards do work. I'm not sure there's a definite list.
