Is a 4K 77-inch LG TV the best option for my elderly parents, considering their limited tech expertise and potential vision problems?

.

Human vision: The maximum field of view for a human is about 120°, so a 77-inch TV is likely to be large enough for your parents to view comfortably from their preferred viewing distance.

Visual acuity: The average person with normal vision can perceive details down to about 10-15 cycles per degree (cpd).

The LG TV's OLED panel is capable of producing over 1,000 cycles per degree, which is far beyond the visual acuity of the human eye.

Color accuracy: OLED screens are capable of producing a wider range of colors than LCD screens, with a color gamut of up to 99% of the DCI-P3 color space.

This is important for your parents as they are likely to watch a lot of Netflix, YouTube, and sports.

Response time: The LG OLED77C3PUAAUS TV has a response time of 2ms, which is incredibly fast.

This means that moving images will be displayed smoothly, with minimal blur or ghosting.

Connectivity: The TV has four HDMI ports, which should be sufficient for your parents' needs.

However, it's worth noting that HDMI 2.1 is becoming more common, and may eventually replace older HDMI standards.

Viewing angle: OLED screens have a relatively wide viewing angle, with a maximum viewing angle of around 178° (slightly less than the screen size).

This means that the TV will still look good from the sides, although color and contrast might suffer slightly.

The LG OLED panel also uses pixel level dimming, which significantly reduces black levels and improves overall contrast.

Smart TV capabilities: WebOS is a popular smart TV platform, offering a range of features such as voice control, multi-device control, and personalized recommendations.

Room lighting: It's worth noting that OLED screens are generally more susceptible to light washout, which can reduce their viewing quality in bright lighting conditions.
