1 Confirmed according to the "National Radio and TV Products Quality Supervision and Inspection Center Evaluation" certificate. For products with authoritative certificates, the most important 6 basic indicators of 4K screens and 4K TVs should all be qualified.
2 Use the micro camera to observe pixel particles and visually compare them with ordinary TVs of the same size. If the pixel granules are densely packed, the product has a high resolution, which is 4K screen.
3 Use a digital camera to capture a white screen and compare the same area or the same number of pixels of the same size screen. The same size 4K screen has more pixels than the normal screen.
2, check the chip.
The chip is a key factor for whether the TV can fully play its 4K advantage. Using a 4K screen TV, getting 4K image effects is critical, depending on whether or not a processing chip that is compatible with 4K screen technology is used.
Check method: Open the "factory menu" of the color TV, enter "system information" to view "local information". A look at whether the product processor is configured for quad-core or above; second, look at whether the 4K decoder chip uses a professional 4K decoder chip.
