OPTIMAL VIEWING DISTANCE
While this value can be different depending on your home and room size, Samsung is one of the brands developing curved TVs that actually conducted an internal study, visiting various homes to figure out the average living room size, preferred screen size and the seated distance from the screen. This investigation revealed that most homes these days have a small living room with a comfortable viewing distance of 3 to 4 meters from their TV.
Based on the viewing distance and the living room size, Samsung determined the optimal curvature of TVs using a radius of 4.2 meters, or also otherwise abbreviated technically as 4200R.
Since most homes either position their sitting furniture at a similar distance from the TV or don’t have a large living room, the same curvature is applied to all their curved TVs, regardless of size. This means, the larger a Samsung curved TV gets, your immersive level increases as the screen envelops you more.
Some manufacturers have a different approach catering to room size such as LG. They’ve chosen to deploy screens with varying curvature depending on screen size, such as 4600R and 5000R. For example, LG’s curved 55-inch EA9800 TV uses a curvature of 5000R. Using a larger radius, this means its curvature is slightly less pronounced than the equivalent sized Samsung model.
Curved TVs offer better viewing angles even at extreme corners, but the optimal distance can be different from TV to TV. For instance Samsung’s TVs are around 4m, LG TVs can range between 4-5m depending on model and size.
