What you hav'nt tryed it ? :lol: I would think its to do with full screen mode if you have the card and drivers that support it. Try it, and come back and post. :)
Edit: Its for watching tv on your monitor . Hence the full screen mode .
Huh?
How can Overlay mode be used for watching TV? All it seems to do is saturate the image more.
Not a lot of info. Sorry.

None of those links help <_<
This is software related...i think. :unsure:
Check your manufacturer or your manul for info.
Done it, just says, to increase performance disable overlaymode.
Video overlay
One screen running on top of another.
So if it's settings for your tv, disable video overlay.
In addition video adapters can be digital whereas regular monitors are often analog, making it have to filter more of the signal when displaying two stacked screens or something.
If it screws up the picture, you ought to turn it on again.
Sometimes, when the picture is bad, on certain adapters it doesn't matter whether you shut it off, or turn it on, just altering it can improve your picture quality if it suddenly goes bad.
But what does running two images on each other achieve?
One guess is that it's like this:Quote:

When you have several windows open on your desktop the information for each still goes out to the monitor or somesuch, only you can only see the topmost one, 'cos that information is noted as visible or such. Possibly this makes for smoother transits or something since it's already loaded in you ram or so.
Whereas when turning it off, the only info that goes out is the visible one.

Overlay mode: The graphics card sets aside an offscreen buffer in its own memory, the image source card (tv card) transfers the picture in there by doing PCI bus master cycles. The graphics card scales, sizes and gamma corrects that, and fits it into the main picture.
In other words it gives the graphics card the opportunity to modify the image according to your preferences, rather than simply take the image as presented. But obviously this takes processing time so you may not get the full frame rate.
yep by buffering the information, saving all the screen info or something.Quote:

Keeping everything available so it can be manipulated on the fly.
Not just the visible, or so I understood it.
