Last week everything on Comcast was fine.
Over the weekend, I noticed the problem - during a baseball game in HD, the score display in the upper left only showed the visitors half of the display. The same problem was visible on the Weather Channel - graphics along the edge were only partly visible.
I tried all the aspect settings - they made the problem worse (including 4:3), as none of them make the source image smaller.
My first thought was that Comcast made some change, but I reviewed my settings in case I accidentally changed something. So, I rebooted the DVR - same problem after.
Current display related settings are:
DVR: Cisco RNG200
Menu>Setup>Screen Position Setup: the arrows are centered on the screen
BTW, the HD Zoom button on the remote has no effect
Menu>Input/Output Assign>Monitor Out>Resolution: Auto
Menu>Source Setup>Picture Adjust>Wide Mode: Auto
Menu>Source Setup>Picture Adjust>Picture Mode: Direct
Menu>Picture>Picture Mode: THX
Menu>Picture>Aspect adjustments>Screen format: Full
Menu>Picture>Aspect adjustments>HD Size: 2
The “FULL” and “2” settings displayed the most picture area
Again, the various aspect settings neither fixed nor improved the problem.
Before I call Comcast (sigh), does anyone have any ideas to try?
Solved! Go to Solution.
From the manual
Stretch and Zoom Program
You can stretch and zoom SD or HD programs by pressing the # key on the remote control.
Also just to ask how is the box connected to the tv? There have been a couple of other postings I believe on this same issue with the same box. It may be the signal coding from the broadcaster not getting decoded correctly.
Thanks and good luck
Thanks for the help.
All the "stretch" functions make it bigger - i need to make it smaller.
I never thought about the decoding in the box, so I checked the SD stations (baseball and Weather Channel) and they are displaying properly.
Maybe it is the box.
Off to Comcast.
I just connected up a LG, model 47LS4500, LED and noticed all the HD channels were displaying too wide and cutting off part of the picture.
I finally figured out the problem was with the "HD Zoom" setting on the Comcast Xfinity DVR box.
You can see the HD Zoom button near the bottom on the Comcast Xfinity remote control.
Pushing this button let me see the entire picture on the HD channels. Hope this helps someone else new to HD channels.
None of the Solutions steps in the "Solutions" area worked for me. I have a Sony 42" and have been through every setup option for the cable box and the TV. I've looked at solving this off and on over the last 6 months.
just purchased toshiba 23 inch led. I have a digital box not an HD. The image is too big for the screen and connot find a solution to reduce the size of the image.
