How much will a 3D TV cost?

As of my knowledge cut-off in September 2021, the pricing of 3D TVs may vary depending on factors like brand, size, technology used, and market conditions. Here's an approximate range of what 3D TVs might have cost at the time:

Budget Range: Simple 3D models in smaller screen sizes (40-55 inches) from lesser-known brands may have started around $250-$500.

Mid-Range: Established brands offering 3D TVs with typical screen sizes (40-55 inches), decent features, and better picture quality might fall in the $600-$1000 range.

Premium Range: High-end 3D TVs with larger screen sizes (55-75 inches), advanced technology (such as 4K resolution, high refresh rates, and advanced 3D features) could be priced between $1000-$2500 or even higher.

Flagship Models: Leading brands' flagship 3D TV models with cutting-edge technology and luxurious designs may have cost upwards of $2500.

It's worth noting that 3D TVs have largely been phased out by now due to the lack of widespread consumer interest and the rise of virtual reality technology. Hence, finding current models or getting precise pricing information may be challenging.
