I've never used a scaler so don't even know really how they work, but I get the feeling they might be useful for me.. I have a 65" panasonic plasma. Unfortunatley it has developed a half height vertical bar in the lower left corner. Makes it very hard to watch. The upside is that to the right of this I have a huge viewing area if I could just move the entire picture into that area. Could a scaler do this? If I input a signal from my cable box into a scaler with a horizontal adjustment, could I essentially shift the picture over to the area of the screen beside the vertical bar? If so, are there certain scalers that anyone would recommend. The input would be either composite or component, and the output would be hdmi, or component, or even a PC-RGB. Thanks for any help anyone can provide!
