Friends who are familiar with TV may know that these two products are flagship products of Samsung and Sony in 2019. The official price of Samsung Q900 TV with 82 inch is 69999 yuan, and Sony's Z9G has reached 9, 9999 yuan, this grade of products, the price factor is not the main factor, positioning and this product, all represent the best product after the brand product design game, which one is better? Some netizens have tested it. Let's have a look.
In this test, BM-7A luminance meter produced by TOPCON company is used as the tester, and the contrast, gamut, color temperature and color saturation are calculated according to the corresponding values, and the corresponding color characteristic map is drawn. Before this test, we first let the machine work normally for one hour continuously and restore it to the factory mode. The whole test environment is carried out in the darkroom.
Test results of Samsung Q900: when the brightness of NTSC is set to 50%, the brightness value is 510 nits, the peak brightness is 1941 nits, the brightness of all black scene is 0.22 nits, and the contrast is 9952:1 (take a bit value).
Test results of Sony Bravia 85 Z9G: when the brightness of 84% color gamut (NTSC) is set to 50%, the brightness value is 377nits, the peak brightness is 1469nits, the brightness of all black scene is 0.29nits, and the contrast is 5065:1 (take one digit value).
The results show that the performance of Samsung Q900 is better than that of Sony's Bravia 85Z9G, and the obvious numerical differences are mainly reflected in the contrast and brightness links. In terms of color gamut, Samsung is also better than Sony. One of the main selling points of quantum dot TV is color, which is a reasonable thing.
Of course, the results of the objective instrument test can not explain everything. Finally, it can present a wonderful picture that pleases the eyes, which is the essence of TV picture adjustment. Next, it is the display of picture test.
Samsung Q900 vs Sony Z9G: Comparative analysis of pictures:
Static picture comparison. The comparison test image acquisition tools are: Sony a7r3 digital SLR camera, lens 24-70, aperture 5.0, IS0 800, shutter 1 / 80s.
In video playback: decoding ability, Samsung Q900 is better than Sony Z9G.
Screen comparison and analysis: Sony Z9G's screen performance is the "common fault" of Japanese manufacturers, and its color tendency is "plain". In the presentation of black field details, Sony Z9G has a very small light leakage phenomenon, which can be ignored. The black field luminance of 0.29 is very close to the limit of naked eye recognition light source, and the black field luminance of Z9G OLED TV, which is also owned by Sony, is only 0.18 after testing. The picture effect of the two products in HDR video playback is very amazing. Samsung has a greater advantage with 1941nits peak brightness. In the contrast between strong brightness and low brightness, the dark field details are better than Sony Z9G.
Through the testing of picture color correction, resolution speed, 8K video decoding speed, 4K picture gain effect, etc., Sony X1 image processing chip flagship and Samsung quantum processor 8K quantum dot processor are completely at the same level in picture resolution force and picture quality processing, slightly insufficient in resolution speed, and the difference is not obvious.
