SS50C
What is the difference in Bios setting for Video Out between UTV and OTV?
2007/03/30
SS50 has UTV and OTV function, default is UTV/NTSC, its stands for underscan and overscan of TVout.
As you know, when enabling TV Out, the picture will not always fill the TV screen. The reason for that is that we use "underscan" if TV Out is enabled in order to make sure that all buttons, especially the ones in the corners of the screen, are fully visible. But the image out is not in full screen mode on TV. UTV is ideal for PC based environment.
There is a bios switch which enables an "overscan" mode for TV Out. This overscan mode results in absolutely no visible border on the TV. The picture coming from the PC will be larger than the picture displayed on TV. OTV is ideal for pure TV-out environment such as Karaoke entertainment or road show demonstrations.
There are some IMPORTANT points you should note:
- Some buttons (close, minimize etc.) may not be accessible if the application is in full screen mode (OTV), they are outside the visible range of the picture.
- Your PC Monitor will most likely switch OFF, because it can not support overscan (some monitor may be switched off automatically)
- The TV Out picture can NOT be adjusted, you can not use overscan and then downsize the picture so that it exactly fits the screen.
