My Joey updated overnight and now all of my channels have extreme letterboxes at the top and bottom of the picture. I've already tried the changing the screen settings by pressing the star key below the 7 on the remote, but the stretch option makes me lose quite a bit of picture by trying to fill the screen. I've also tried adjusting the screen settings aspect on the TV itself, but that doesn't solve the problem either. Is there a setting I can use or cancel the update so that I can get the picture to fill the screen without losing any of the picture on either side?
For what it's worth, I had a similar situation. Unplugging the HDMI cable for a few seconds fixed the problem for me.Once I re-connected the cable the image was restored to full screen and high definition. Not sure if it's a universal fix, but might be worth a try.
