为什么不选择70寸电视？

There are several reasons why one might not choose a 70-inch TV， despite its large screen size.

1. Price: 70-inch TVs tend to be more expensive than smaller TVs. If you're on a budget， you may not want to spend the extra money on a larger screen when a smaller TV can offer similar features and picture quality.

2. Space: Depending on the size of your room， a 70-inch TV may not be practical. It can take up a lot of space and may overwhelm smaller rooms. Additionally， if you're sitting too close to the TV， you may find that the large screen size can be uncomfortable for your eyes.

3. Viewing Angle: When you have a large screen size， the viewing angle becomes important. If you're watching from an angle that is too steep， you may experience distortion or reduced picture quality. This can be particularly difficult to manage with a 70-inch TV， which has a wider viewing angle.

4. Picture Quality: Not all 70-inch TVs are created equal. Some models may not have the same level of picture quality as smaller， more expensive models. When choosing a TV， it's important to consider factors like contrast， color accuracy， and brightness to ensure that you're getting the best picture quality possible.

5. Energy Consumption: Larger TVs tend to consume more energy than smaller ones. This is something to consider if you're looking to minimize your energy bill or if you're concerned about your impact on the environment.

Ultimately， the decision to choose a 70-inch TV depends on your personal preferences and needs. While a large screen size can offer an immersive viewing experience， it's important to consider factors like price， space， and picture quality before making a purchase.
