16 X 9 Programming & channel 21-4
On December 17th WXXI started converting all programming from a 4x3 aspect ratio to a 16x9 ratio... this means that programs viewed on a 4x3 (old style set) will be letterboxed. This means the picture will be smaller and have black bands at the top and bottom. Some programs are still being fed to WXXI from PBS already in a letterbox format this adds even more 'black' area on the sides. If the viewer is using a set-top box, there is a feature that allows the viewer to 'zoom-in' to improve the picture size.
