Hi guys,
Ive gone and done it. Just purchased an old SK2 rig of ebay. Very excited.
I remember seeing a post a while back but can no longer find it.
Does anyone happen to know how i can view 16:9 images as letterboxed on a 4:3 monitor rather than seeing my image all squished? Is there an add-on to make this possible?
Many thanks

The whole principle behind 16:9 is to squeeze the image horizontally in the camera, like anamorfic images.
This means that when you project or playback on a tv-system you need a W I D E R canvas, a wider tube or LCD to get back to normal (un-squeezed)
That is a problem, as the monitor has fixed dimensions. your only option to come closer to the 16:9 format is to squeeze also in the vertical direction, making it "letter-boxed" but in fact you press all the scanning lines into a smaller area. (Letter-boxed = using the full height but making black bars on top and bottom.)

There is a variable resistor inside the monitor housing that controls the scanning height, this is what you need to adjust, but it will always a rough adjustment.
