How to Make the Picture Fill the TV Screen: The Ultimate Guide

Having a picture that doesn‘t properly fit the television screen is a common issue that can detract from your viewing experience. Fortunately, with the right settings adjustments, you can remove black bars, eliminate cutoff pictures, and make the image fill the screen on any TV.

What Causes the Picture to Not Fit the Screen?

The main culprit for a picture that doesn‘t fit the screen is something called overscan. This refers to when a TV cuts off the outer edges of the source signal to varying degrees, stretching the remaining image to fill the screen.

Overscan was necessary on old CRT televisions to account for variances in broadcasting equipment and connections. But it causes unnecessary picture loss on modern fixed pixel screens. Despite this, many TVs still default to a zoomed in picture with 5% or more overscan.

According to the Video Electronics Standards Association (VESA), 0% to 2% overscan is acceptable on fixed pixel displays to allow for manufacturing tolerances. But ideally a setting of 0% overscan should be used to eliminate cutoff edges.

Another common reason for black bars or an improperly fitted picture is differences between the aspect ratio of the content and display. Aspect ratio refers to the proportional relationship between the width and height of an image.

Modern widescreen HDTVs have a 16:9 aspect ratio, meaning the width is 1.78 times the height. Older standard definition programming was made in the more square 4:3 ratio, where the width is 1.33 times the height.

This mismatch results in black bars on the sides for 4:3 content on a 16:9 screen, or letterboxing black bars for wider 2.35:1 cinematic aspect movies.

Adjusting Picture Settings to Fit Screen

Nearly all modern televisions include settings to eliminate overscan and adjust the aspect ratio or screen size. But accessing these can vary by manufacturer and model. Here are some general steps for major brands:

Samsung

1. Press Home button on remote and select Settings
2. Choose Picture, then select Picture Size
3. Change from Standard (default zoom) to Screen Fit to eliminate overscan
4. Adjust to 16:9 for fitting widescreen content with black bar options

Sony

1. Find Aspect Ratio setting under Screen in main Settings menu
2. Select Wide Mode to expand 4:3 SD content to fill the screen
3. Choose Normal for 1:1 pixel mapping with no overscan
4. Adjust Display Area Setting to remove cutoff edges

LG

1. Go to Picture Settings in the main menu
2. Select Aspect Ratio and choose Original/Just Scan to eliminate overscan
3. Use 16:9 for fitting widescreen video, Cinema Zoom for movies

Vizio

1. Go to System menu and select View Mode
2. Choose Fill Screen to remove overscan and fill display
3. Adjust Size & Position settings to fine tune as needed

Using these settings, you can adjust the amount of zoom precisely for the content type to eliminate cutoff edges and maximize picture size.

Using Remote Control Shortcuts

Most television remotes also provide quick access shortcuts to change the picture size right from your seat:

• Aspect – Cycles through various aspect ratio presets
• Size/Zoom/Magnify – Resizes image from default
• Screen Fit/Fill – Removes overscan and fills screen
• 1:1 Pixel – Shows true native resolution with no scaling

Experiment with these buttons to easily find the ideal settings for a given movie, TV show, or game console output.

Adjusting External Device Resolution

If the picture looks very blurry and pixelated on your TV, the likely culprit is the output resolution from your cable box, streaming stick, Blu-ray player, or other source doesn‘t match the native resolution of the television panel.

To fix this:

1. Check the TV manual to find the optimal resolution, typically 1080p, 4K or 8K
2. Adjust device video settings, often under Video, to match this resolution
3. Use automatic/native resolution output mode on source device if available

Matching the source and TV resolutions as closely as possible will provide the cleanest picture.

Dealing with Black Bars from Aspect Ratio Mismatches

Due to differences in aspect ratios between content and display, black bars will often remain on certain movies and TV shows:

• Vertical bars on 4:3 standard definition video
• Letterboxing on wider 21:9 and 2.35:1 cinematic aspect ratio movies
• Horizontal bars for ultra-wide 32:9 PC gaming content on a 16:9 TV

According to IMDb, since the 1950s the most common aspects ratios used in movie production have been:

1.85:1	55%
2.35:1	21%
1.66:1	9%

With over 75% wider than 16:9, letterboxing is unavoidable without cropping the picture.

Here are some settings that can help minimize black bar distractions:

• Justify/Vertical Expand – Stretches 4:3 SD image vertically to fill screen
• Edge Fill – Zooms in only on the edges to fill sides
• Zoom/Crop – Enlarges image but will cut off outer edges

Note these can cause significant distortion so use sparingly where needed. Leaving small black bars is recommended for the truest picture in most cases.

Optimizing Settings for Each Input Source

Picture settings are often specific to each input source. For example, an HDMI 1 port may be configured very differently than HDMI 2 or Antenna or Smart TV apps.

Get in the habit of checking the picture menu for each type of input used. Also ensure device-specific settings like Just Scan or game modes are enabled on every relevant HDMI port if needed.

Certain inputs like PC mode may default back to overscanning when switched, requiring Screen Fit or 1:1 Pixel to be re-selected each time.

According to a 2022 consumer survey by Display Supply Chain Consultants, the average US household has over 4 devices connected to their TV, requiring optimized settings for each.

Avoid Excessive Enlargement and Distortion

When faced with black bars around content, take care not to zoom in too much as this can cause a distorted, pixelated image:

• Standard definition video at 480i/480p will look blurry if expanded to fill a 4K screen
• Avoid Justify modes for text and tickers which will appear unnaturally stretched
• Letterboxed movies will lose visual information from the top and bottom when zoomed

Properly calibrating all of the picture settings is important for balancing screen size with high quality visuals. This includes:

• Brightness/OLED Light
• Contrast
• Color/Tint
• Sharpness
• Motion smoothing
• Local dimming

Research from the UHD Alliance shows image quality noticeably degrades when enlarging under-sized content more than 1.5X in any dimension on a 4K display.

Additional Tips for Picture Quality

To ensure the very best picture, keep these other guidelines in mind:

• Set HDMI ports to Enhanced mode for highest bandwidth, enable chroma 4:4:4
• Match TV and source frame rate and dynamic range capabilities
• Angle TV towards seating positions to maximize contrast and brightness
• Ensure sufficient brightness for room conditions to bring out shadow details
• Have display professionally calibrated for color accuracy

Following the manufacturer‘s optimal setup recommendations tailored for different display technologies like OLED, QLED, LED LCD will help maximize your viewing enjoyment.
