I have three televisions, all old style box sets, no HD, 1 is 32" and the other 2 are 18" or so. My main X1 box is on the larger television and the smaller sets have the smaller "slave" boxes on them. For both of my smaller sets, I turned on the television the other day and the picture only filled about 1/3 of the screen in the upper left corner of the screen while all menus and the guide would fill the screen. On one, I restarted the box, no change. I unplugged and recycled, no change. I went into the display settings and chose selected the same resolution that it was on which is the lowest resolution in the selection list. This made the picture full screen, but it made the menus so that they are too large and run off the screen. When I hit the xfinity button, I can barely see the top of the word "xfinity" at the bottom of my screen. When I type in a channel, I can't even see that at all because it's on the right and offscreen. The guide looks blownup (enlarged) and I can only see the top four channels of the list. So one of my small sets, I re-selected the low resolution display and said yes to keep it and the set now acts as described above. The second smaller set still has the small picture in the uppper left screen and if I go to re-select the resolution, it would change into what I have described above, but on that one I have said "no" and did not keep the settings so it goes back to the small picture. On my main set, the larger set, everything seems to be fine except on Friday and Saturday I noticed that when I would start to watch a DVR'ed program, when the "DVR" image would appear, it was too large to fit the screen and I only saw the top left of the "D" and maybe part of the "R." Last night (Sunday night), that seems to have been fixed and I now see the "DVR" screen like I'm supposed to. This must be something that Comcast reprogrammed because both of the smaller "slave" boxes act the same and the one has been reset several times with no fix.
