I finally got around to trying the 1:1 pixel fix using the .ts files reported earlier. Much to my amazement, it does work exactly as stated. I can't say anything about true 1:1 since I don't know anything about it, but the effects described here did take place.
I loaded the vertical.ts file and saw the moiré pattern around the edge of the screen.
I entered the SM and pressed 0 to display the submenu, then I entered the Manual Geometry screen.
After moving the first crosshair one click (in any direction) I pressed Select to save the change.
The .ts file was then displayed again and all the moiré patterns were gone. Completely.
Now, I did notice that there are some geometry problems after doing this. The 4:3 lines and the 16:9 lines were bowed. I went back into manual geometry and selected Page Down to get to the 4:3 adjustment. After a few clicks on FF I found one that was straight. Then I clicked Page Down once more to get to the 16:9 adjustment and did the same.
After exiting the SM the moiré patterns were still gone.
I don't know what to think about all this since it was already stated that these units did not support 1:1. Yet the steps described seem to indicate otherwise.
Try it for yourself.
