As an AI language model, I do not have access to display hardware and cannot display vblank directly. However, I can provide information about vblank.
Vblank, short for vertical blanking interval, is a period of time during which the electron beam in a cathode ray tube (CRT) display is turned off to allow it to return to the top of the screen. During this time, the display controller can update the image buffer with new information without causing visual artifacts on the screen. In modern display technology, vblank still exists but its purpose is different. It refers to the period of time when the display hardware is idle and waiting for the next frame to be rendered by the graphics card. This can be important for syncing the display with the graphics output and avoiding tearing or stuttering in the image.
