What are the symptoms of a broken HDMI cable?

1. The HDMI cable may have a problem. Currently, the highest version of HDMI 1.4 supports four major functions (3D, Ethernet transmission, audio return, 2160P resolution 4Kx2K). The dirty cable is not only lower than 1.3, but also the core is not the standard 19 core, which is a serious case of cutting corners. It is recommended to buy branded products.
2. Please check whether the TV signal input channel is adjusted to [HDMI input]. Under the TV, PC, and AV input channels, there will be no signal display.
3. Can the TV be recognized normally in the control panel of the nVIDIA graphics card driver? If not, you can force the TV to be recognized.
4. The HDMI function of some desktop motherboard integrated graphics cards may require motherboard jumper settings (DVI HDMI mode switching).
5. The TV interface may not match the HDMI cable interface. At this time, you can try using an HDMI adapter.
6. Make sure the graphics card driver is normal. It is recommended to use Windows 7 and above to support all HDMI features.
