When I played an anamorphic PAL DVD on a 4:3 CRT, the picture would look vertically stretched until I pressed the 'aspect ratio' button on the TV.
This would correct the display, but how did it do it? Was it by drawing the same number of scanlines, but reducing the vertical distance between each line?
I've never used a 4:3 CRT that could deal with different aspect ratios like that.
Was the CRT natively HD, or SD? Was it zooming in on the middle of the frame, or letterboxing?
I don't remember the model. It was a Sony CRT that I bought for about 600GBP in maybe 1997?
Back then, there was no concept of SD or HD. PAL has 625 scanlines (~576 visible). No fixed horizontal resolution.
