I am having a bit of a conniption fit over the compatibility of the widescreen modes between these 2 components. In the Sony's menu I have it set to 16:9 output. I have been playing the Avia test disc's 1.78:1 test signal to see how the Panasonic formats the image on each of it's aspect ratio settings. The Panny has a 4:3 setting which obviously keeps the image in the center with gray bars on the sides. OK. There is a setting called "Full" which seems to stretch the 1.78 image to the sides of the screen but there is still space above and below the edges of the 1.78 area, which is not what I expect. I expect the 1.78 image to exactly fill the screen on this setting, since it matches exactly the aspect ratio of my display. The last setting available (on the component inputs at least) is called "Zoom" which does just that, but it cuts off the top, bottom and sides of the 1.78 image area just a bit, and there is a very perceptible loss of resolution. Am I missing something here? Shouldn't there be a setting where the image is neither stretched or cropped and just fills the screen? Obviously I would expect slight bars on top and bottom for 1.85 movies and larger ones for 2.35. It seems like when I change the setting from 16:9 to 4:3 on the DVD player that nothing changes on screen. I would guess this probably would be applicable to anyone with a 16:9 display. Any insights would be appreciated.
