Best Tips to Fix Samsung TV Not Showing or Displaying Full Screen Picture Error

But there’s good news: it’s usually an easy fix. This quick guide will show you a few tricks to get your Samsung TV displaying a full screen image, no matter what you’re watching.

Solution #1 – Make Sure the Source Device Resolution Matches Your TV

  • Today’s TVs display content in ultra-sharp 4K resolution
  • But your cable box may only output an older 1080p signal
  • This prevents the TV from filling the screen fully
  • Check your playback device video settings for output resolution
  • Match that to your Samsung TV’s native display resolution
  • For 4K TVs, set cable boxes, streaming sticks, etc to 3840 x 2160
  • Consult manual if unsure of TV resolution

See if tweaking the video settings on your cable box, Blu-ray player, streaming stick or game console to match your Samsung TV’s native resolution solves the issue.

Solution #2 – Fiddle with Your Samsung’s Picture Size Menu

  • Most Samsung TVs let you manage display modes
  • Find “Picture Size” menu in Settings > Display
  • Choose from Full Screen, Fit to Screen, 16:9, etc
  • Full Screen forces input to match TV’s dimensions
  • Fit to Screen stretches picture to eliminate black bars
  • Toggle modes to get desired full screen effect

If output resolution matching doesn’t work, diving into your TV’s Picture Size menus provides more options like forcing full screen display or fitting/stretching content.

Solution #3 – Securely Reseat All Video Input Connections

  • A loose HDMI cable can prevent full screen display
  • Disconnect cables from TV and playback devices
  • Securely reinsert all connections fully
  • Try different HDMI ports on TV if available
  • Test with different HDMI cables if possible
  • Bad cables can cause handshaking issues

It never hurts to unplug, inspect, and firmly reconnect all HDMI or other video cables between your Samsung TV and the source equipment. Faulty cables are more common than you think. Swap ’em out!

Solution #4 – Factory Reset Samsung as Last Resort

  • If all else fails, reset your TV
  • Go to General Settings > Reset
  • Choose reset picture settings or full factory reset
  • Will erase all custom display adjustments
  • Allows you reconfigure like brand new

When desperate, restoring factory default video settings is an option. Just know it’ll wipe out any custom tweaks you’ve dutifully dialed in over the years. Sometimes it’s the nuclear option that works when nothing else does!

What If My Samsung TV Has Black Bars On All 4 Sides?

Don’t you just hate the movie theater “letterbox” look on your nice TV? Fear not – chances are pretty good a quick settings change will banish those black bars for good.

  • Check your Samsung’s Aspect Ratio first
  • Find the Picture Size control options
  • Cycle from 16:9 to Full Screen
  • This signals the TV to enlarge picture
  • Eliminating side and top/bottom black bars

By explicitly telling your Samsung to display a full screen image, you can override the native aspect ratio signal from devices like Blu-ray players. Most of the time this stretches the video perfectly.
