"What are the right settings for achieving 4K video enhancement without using external tools?"

Enabling Game Mode on your TV or monitor can optimize display settings for 4K gaming by fine-tuning visuals and frame rates.

HDR (High Dynamic Range) enhances color and contrast, providing a more vibrant and realistic gaming experience.

Adjusting color settings, brightness, contrast, and gamma can further optimize the visual quality of 4K content.

Some TVs offer Eco or Power Saving modes that can be adjusted to prioritize bright, high-contrast pictures.

Upscaling or super resolution algorithms can enhance image quality even for non-4K content.

Lowering the gamma setting can make the picture brighter, but may make it more difficult to see details in highlights of the image.

Raising the gamma setting to 2.4, for example, can improve picture quality.

The "sharpness" setting on your TV controls artificial edge enhancement, not image sharpness.

Tweaking your sharpness settings can reduce edge enhancement to give you a clearer picture.

The "vivid" and "dynamic" picture modes tend to overemphasize contrast and sharpness, and lower brightness too much.

Using a calibration disc or having your TV calibrated by a professional can ensure optimal picture settings.

Enabling HDR on your TV can enhance color and contrast in games for a more vibrant and realistic experience.

Adjusting power settings and enabling hardware-accelerated GPU scheduling can improve 4K gaming performance.

Most TVs are automatically set to a "standard" mode, which may not provide the best picture quality.

Changing the picture mode, color temperature, backlight, motion enhancer, gamma, and edge enhancement can improve picture quality.

Using an excellent streaming device, box, or console that supports 4K content can ensure optimal video quality.

Having a strong internet connection is necessary for streaming 4K content smoothly.

Using the right HDMI cables can ensure that 4K content is transmitted correctly.

The "Movie" or "Standard" picture mode can provide a good starting point for calibrating your TV.

Calibrating your TV manually requires adjusting the picture mode, brightness, contrast, and gamma settings.
