15． Why does my newly purchased flat-panel TV, the Portrait deformed and cannot be watched normally
1) This phenomenon is not caused by the malfunction of the TV itself. It is due to the fact that most ordinary TVs currently receive 4:3 analog signals, but all flat-panel TVs now use 16:9 screens, different signal ratio and display ratio caused this issue. But usually, 16:9 screen TV will also have other image modes, such as program source mode, which displays the received signal in the same proportion, and the display ratio depends on the program source. That is, if the program source is 4:3, it will display 4:3; if the program source is 16:9, it will display 16:9.The image distortion phenomenon of flat-panel TVs is mainly because the display format is 16:9, which is different from the 4:3 of ordinary color TVs. The main reason is that the display screen is made with a 16:9 aspect ratio, so the image effect is relatively flat and people will change fat. Tablets generally rarely shifting. You can check the image aspect ratio mode on the remote control if it is zooming in, if yes, there will be a phenomenon that the image is enlarged to that the logo can only be seen halfway or not. You can adjust the display format to 16:9.
