Hi The monitor(we call it second monitor) is connected with a PC(win8). Suddenly, the second monitor cannot show anything, it is black, but from aspect of the PC monitor, the PC monitor seems to have the connection with the second monitor because when I plug in and out the second monitor to the PC, the PC monitor behavior is the same as before. The second monitor still has power light blink. it looks like the second monitor cannot get signal from the PC. I check the connection many times, and all are Ok. What is wrong?

It is monitor issue ?

A monitor or a display is an electronic visual display for computers, usually comprised of the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size. They are connected to the computer via VGA, DVI, DisplayPort, Thunderbolt, LVDS or other proprietary connectors and signals.

Windows 8 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems, with an emphasis on improving its user experience on tablets. In particular, these changes included a touch-optimized Windows shell based on Microsoft's "Metro" design language, the Start screen, a new platform for developing apps with an emphasis on touchscreen input, integration with online services, support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware.
