******************************************************************
Q: How does one adjust contrast and aspect ratio settings ?
A: As shown in the video...
***********************************************************************
Relevant background: What it is: Brightness difference between white and black. This is the main component of picture quality. When it matters: Always, but especially when watching dark scenes... The contrast ratio is the ratio between the luminance of the brightest white and the darkest black that a TV can produce. Larger contrast ratios work out to deeper blacks, which make a big difference to overall picture quality. It’s of particular importance for dark scenes in movies and TV shows...To test contrast, we measure the luminance of both white and black, and then calculate the ratio between the two. Luminance is a metric to measure the amount of light (or intensity) present on a surface and is expressed in cd/m2. For TVs, the brighter the light of the screen is, the higher the luminance will be.” ("Contrast Ratio of TVs", https://www.rtings.com/tv/tests/picture-quality/contrast-ratio)

Relevant material on farsightedness: "If you are farsighted, you involuntarily exert extra effort to maintain clear distance vision and even greater effort to see clearly at close range. This extra effort can cause fatigue, tension, discomfort and headaches. If the crystalline lens of the eye cannot bring the object into focus, blurred vision occurs." ("Hyperopia (Farsightedness)", https://opto.ca/health-library/hyperopia-farsightedness)

Global statistics: "It is estimated that more than 1 billion individuals worldwide in 2005 had presbyopia, or age-related difficulty in seeing objects nearby, with an estimated 410 million with the condition unable to perform tasks requiring near vision, according to a new report" ("Age-related Farsightedness May Affect More Than 1 Billion Worldwide", https://www.sciencedaily.com/releases/2008/12/081208180329.htm)
