Large TV manufacturers have long started to produce models that support the 3D function. To choose the right 3D TV, you need to know several important nuances and differences.
Instructions
Step 1
Choose the 3D technology that's right for you. Discard models that allow you to view 3D images without additional accessories. Their image quality and 3D depth are much lower. Two types remain: active and passive 3D. The advantages of the first type include the high quality of the volumetric image and the preservation of the full resolution of the picture. Be sure to test your TV with 3D active (shutter) function before purchasing. Some people experience severe eye pain after prolonged use of this type of 3D glasses.
Step 2
If you want to save money, get a passive 3D TV. It is important to take into account that the resolution of the picture when viewed in 3D glasses will be 2 times less than the original one. This is due to the fact that each eye receives only half of the total image. In addition, the 3D depth will be lower than that of active technology. Some companies release films in 1920x2160 resolution, which allows you to completely preserve the original image quality.
Step 3
Select the type of TV. The advantages of models with a plasma display include their low cost, high scan rate and no flicker. The main disadvantages: high power consumption and large size of the TV.
Step 4
Modern models of LCD TVs with LED backlighting are not much inferior to plasma ones. The introduction of new technologies has greatly increased the refresh rate of the picture and improved the image quality in general. Do not purchase a 3D TV with an old type of backlight. These models are very outdated.
Step 5
Pay attention to the sweep frequency. For plasma TVs, this parameter always remains at a high level. LED TVs with 3D function must have a frequency of at least 400Hz. Image distortion will be especially noticeable when using passive 3D.
Step 6
Be sure to check for HDMI version 1.4. Earlier modifications are not capable of realizing a high data transfer rate, which will manifest itself in the form of image "freezing" or even frame skipping. Modern TVs have connectors for connecting flash cards and hard drives. It is better to use a USB 3.0 port for watching a 3D movie in high definition.
Step 7
Decide on your screen size. Practice shows that the diagonal of a 3D TV should not be less than 42 inches. It is important to remember that the distance to the viewer should be approximately equal to 2 diagonals. In the case of 3D TVs, this is extremely important, because the effect of volume can be greatly distorted when viewed too close.
