I use a VGA to SDI convertor to capture computer VGA signal into my TCB.
But now I met a problem:The screen of computer at desktop can see the task bar,but the video which I captured can't display the complete the whole task bar,it only can display half of it.how can I make the complete task bar in my captured video?

Though traditional VGA was 640x480 (easily converted to SD video), VGA adapters can put out a whole range of resolutions - most of them HD and well beyond standard def NTSC. What resolution is the computedr display set at? Does the VGA-SDI adapter you have do video scaling to put out an SD signal, or does it just crop?

BTW - Any reason you're not using iVGA to do this?

Also, depending on the details of your pipeline, don't forget about overscan...
