Viewing SD channels in 16:9 are not full screen anymore

by tdot23 / June 15, 2010 3:27 AM PDT

I purchased an LN55C610 last week, and hooked up my HD box with component cables.

I had the Picture Size settings set to 16:9 and all channels would fit all across the screen (HD and non HD)

Yesterday, I decided to change cables, hooking up a DVI > HDMI cable from my HD Cable box to the TV, and now the non hd channels will not display across the full screen as they did before in 16:9 (I have to use the "wide" setting, but now the bottom and top of the non hd channels are cut off)

In an effort to get my picture size settings back (in 16:9) I switched back to the component cables, and it still hasnt changed to the original settings.

Is there a reset I can do to restore how I was originally receiving all non hd channels in full screen 16:9 format?

You might check the output signal and aspect ratio of the output signal in your cable box menu settings. Those settings may have changed when it detected a HDMI cable rather than the component cables. HDMI sends a 1:1 pixel representation to the television, so it's quite possible that would have happened by default.

Cable box menu

I had just checked the cable box menu before coming here, and lo and behold, the 4:3 override had been switched off. (DCT6200)

Thanks for the input nonetheless

How to make SD Channels full screen
by iJu5tin / June 30, 2013 12:08 PM PDT

First off when you go into the TV setting and set it to 16:9 that is telling the tv to display the feed in a 16:9 form. But if you have a cable box (which you have to to have HD channels) SD channels can only come in thru as 480i which can only come in thru 4:3 setting, unlike HD channels that come thru as 1080i and 16:9. So if you have the cable box set to "Stretched" then it will stretch the picture of the SD channels to fit the screen. But then sense the HD channels were already coming in on full screen it stretches them bigger than your TV screen. I had the same problem with my TV, to resolve this i went into the cable box setting and changed the picture format from "Fixed" to "Auto DVI/HDMI" which then made my SD channels full-screen making then 480i (like they were as when they were set to "Stretch") and then when i go to an HD channel it changes the setting to 1080i to fit the screen. The reason why your Cable box originally put the SD channels in 4:3 is because it was fixed to 1080i. With it set to "Auto DVI/HDMI" it will automatically switch between 480i and 1080i to fit your tv screen. Hope that helped! Happy

We are unable to change any settings on our cable box, per your recommendation. We have Comcast and they say settings can't be changed on the box.
