Nadeem, First, GDAL does not provide any visualization utilities so it seems likely you are opening the file in an application that uses GDAL. What application is that?
Second, could you perhaps point us to your PNG file? They come in a variety of configurations. If nothing else, a gdalinfo report on the file would be helpful for us to provide useful commentary.
