Why Is My TV Picture Too Big or Cut Off?

When your TV picture is too large for the screen, it is almost always caused by one of these reasons:

  • Incorrect Aspect Ratio setting on the TV
  • Overscan being turned on (TV zooms in slightly, cutting edges)
  • Wrong resolution set on your connected device (PC, PS5, streaming stick, etc.)
  • Wrong HDMI or input settings on the TV
  • Zoom mode accidentally enabled

The good news: this is almost always fixable in minutes without any tools.

Method 1: Change the Aspect Ratio / Picture Size Setting

This is the most common fix. Nearly every TV has an Aspect Ratio or Picture Size setting.

How to Do It (All TV Brands)

  1. Press the remote button labelled one of the following (varies by brand):
    • RATIO, P.SIZE, PICTURE, FORMAT, ZOOM, or WIDE
  2. Cycle through the options until the picture fits properly. Try:
    • 16:9 – Standard widescreen (most common fix)
    • Normal / Original – Displays the image at its native size
    • Just Scan / Screen Fit / Dot by Dot – Removes overscan (best for HDMI)
    • Auto – Lets the TV decide automatically
  3. Avoid these options if the picture looks too big:
    • Zoom, Zoom 1, Zoom 2, Wide Zoom, Full — these magnify the image

By Brand — Where to Find the Setting

Samsung TV

  1. Press Menu → Picture → Picture Size Settings
  2. Set Picture Size to 16:9 or Screen Fit
  3. Also check: Fit to Screen → Turn ON

LG TV

  1. Press Settings (gear icon) → Picture → Aspect Ratio
  2. Select 16:9 or Just Scan
  3. On newer LG: Settings → All Settings → Picture → Aspect Ratio Settings

Sony TV

  1. Press Home → Settings → Display & Sound → Picture → Screen
  2. Set to Full, Normal, or Wide Zoom as needed
  3. Or press the Wide button on older Sony remotes

Hisense TV

  1. Press Menu → Picture → Aspect Ratio
  2. Choose Auto or 16:9

TCL TV

  1. Press Home → Settings → Picture → Aspect Ratio
  2. Set to 16:9 or Auto

Method 2: Turn Off Overscan

Overscan causes the TV to zoom in slightly, cutting off the edges of the picture. This is very common when connecting a PC or games console via HDMI.

What Is Overscan?

Overscan is an old TV technology that crops the edges of the image. On modern TVs and HDMI connections, it should be turned OFF.

How to Disable Overscan

Samsung

  1. Menu → Picture → Picture Size Settings
  2. Set Picture Size to Screen Fit
  3. Or: Settings → Picture → Custom Size → adjust to 0 on all sides

LG

  1. Settings → All Settings → Picture → Aspect Ratio Settings
  2. Turn Just Scan → ON (this disables overscan)

Sony

  1. Settings → Display & Sound → Picture → Screen
  2. Select +1 (full pixel display, no overscan)

Other Brands

  • Look in Picture Settings → search for “Overscan” and set it to OFF

Method 3: Fix the Resolution on Your Connected Device

If the picture is too big because of a PC, laptop, PS5, Xbox, or streaming device, you need to match its output resolution to the TV.

For Windows PC / Laptop

  1. Right-click on the Desktop → Display Settings
  2. Scroll down to Display Resolution
  3. Set it to the Recommended resolution (usually 1920 x 1080 for Full HD or 3840 x 2160 for 4K)
  4. Click Apply → Keep Changes

For Mac

  1. Apple Menu → System Settings → Displays
  2. Choose Default for Display or manually select the correct resolution

For PS5

  1. Settings → Screen and Video → Video Output
  2. Set Resolution to 1080p or 4K (match your TV)
  3. Disable Enable 4K if your TV is not 4K

For Xbox

  1. Settings → General → TV & Display Options
  2. Set Resolution and Refresh Rate to match your TV specs

For Fire TV / Roku / Android TV Stick

  1. Go to device Display/Screen settings
  2. Match resolution to TV — usually 1080p is safest

Method 4: Adjust HDMI Settings on the TV

Some TVs apply a different picture size specifically for HDMI inputs.

Samsung

  1. While watching the HDMI input, press Menu
  2. Go to Picture → Picture Size → select Screen Fit or 16:9

LG

  1. Press Settings → All Settings → Picture → Aspect Ratio
  2. Enable Just Scan

Sony

  1. Settings → Display & Sound → Screen → Display Area
  2. Set to Full Pixel

Note: Some TVs have a separate HDMI Picture Size setting that only appears when an HDMI device is connected.

Method 5: Check the Source Device’s Output Settings

Sometimes the streaming app or the device itself is sending the wrong image size.

  • Netflix / YouTube / DSTV App: Check app video quality settings — make sure it matches your TV resolution
  • Cable/Satellite Box: Access the box’s settings menu and change output from 480i/576i to 1080i or 1080p
  • DVD / Blu-ray Player: Set output resolution in the player’s settings to 1080p

Still Can’t Fix It?

If you’ve tried all the above and your TV picture is still too big or cut off, there may be a deeper hardware or software issue such as:

  • A corrupted firmware on your TV
  • A faulty HDMI port
  • A broken T-Con board affecting display scaling
  • A panel alignment problem

These require professional diagnosis and repair.

Frequently Asked Questions

Why does my TV picture look zoomed in?

This is usually caused by the Aspect Ratio being set to Zoom or the Overscan setting being turned on. Go to Picture Settings and change the size to 16:9 or Screen Fit.

Why is my HDMI picture bigger than the screen?

This is almost always an overscan issue. On your TV, find the HDMI picture size setting and select “Just Scan,” “Screen Fit,” or “Full Pixel” depending on your brand.

How do I fix a stretched TV picture?

Press the RATIO or FORMAT button on your remote and cycle through options until the picture looks correct. Selecting “16:9” or “Normal” usually fixes stretching.

Can a wrong resolution cause the picture to be too big?

Yes. If your connected device (PC, console, or streaming stick) outputs a resolution higher than what the TV handles, the picture may overflow the screen. Match the output resolution to your TV’s native resolution.

Do I need a technician to fix picture size issues?

Usually no — it can be fixed in the TV settings. But if the problem persists after all adjustments, a faulty hardware component may be involved and a technician is recommended.
