My 14 inch Sony Trinitron from the 8833 era did the same, 60hz mode on ST or Megadrive stretched the screen so no border.
I've got both you guys beat I have a Sony 20" Professional RGB Video Monitor that does both PAL and NTSC even have an amiga rgb cable for it!
A couple of things really cool about 1080 is that the top of the case is flat so you can put something on top comfortably. Also as stated earlier having the Cool Amiga Logo is priceless!
One thing I love about the 1084 white monitors with commodore in blue is the front push button to select RGB/CVBS compared to lame D1 and D2 revs where you have to push the button in the back of the case!
