Okay so we are heading for HDTV in 06 with SKY. And we know that different channels are broadcast in different aspect ratio 16:9, 4:3 and so on. So many large CRT TV have been able to automatically change the aspect ratio through scart (pin 8) line 23 etc. This feature has also been incorporated to large flat screen (but not all) and some of us may have encountered problems with this. Irrelevant. So my question to us all is this: HDMI or DVI for HDTV how are they going to detect the aspect ratio for different channels? Answers on a postcard please!
