The selected window really looks brighter and sharper, making the image much better to look at. It brings more life to the image.

It should work with any video card, althoug I have used only two NVIDIA and one SiS video cards with it up to now. Currently I am using a NVIDIA GeForce 2 MMX 400 64MB card. The CD that comes with the monitor has a program that is used to activate the "light frame" feature in the desired window. When run, this program puts an icon in the tray area of the taskbar. To apply the feature to a window, it is enough to click on the program icon in the tray area an then clicking in the window. The window will be brighter and sharper then.

As alread said, the feature is tied to the monitor and is activated by a program for this specific purpose. It is not related to the video card. I will contact the manufacturer (Philips) and ask about avaiability of technical specifications for the manufacturer. But I do not have the time and maybe the skills needed to add this functionality to XFree86 (although I am a programmer, I have not done X Window programming yet). Once available the technical specifications, it would be nice if a XFree86 developer could add the feature to XFree86. Is there anybody else using a monitor with the "light frame" feature?
