how is the first computer monitor
you restart the computer then turn it on again
A computer can not turn off by itself. The monitor just turns blank it you leave it. To turn off the computer you have to prees the on button on your computer. If you press the botton on the monitor it is not turning the computer off... just the screen.
The first thing I would try is to hold down the menu button for 15 seconds. This should work but if it doesn't then try this: * Turn the computer and monitor off * Disconnect all monitor cabling from the monitor (power, USB, VGA, DVI, etc.) * Press and hold in the monitor power button in for 5 seconds * Reconnect the monitor to the computer * Reconnect the monitor power cord to the monitor * Turn on the monitor, then the computer * Press the Menu button for 15 seconds to unlock the padlock feature
Check your cord from the computer and monitor. If that is ok check your video card.
If it has been working normally before this--no black border--then the monitor may have become unplugged from the computer. Shut down the computer. Unplug and then replug in all of the connecting wires, make sure the On button on the monitor is on. Image should be there when you turn the computer back on. If this doesn't work, try hooking the monitor up to another computer. If you have the same issue, the problem is the monitor. If not, the first computer is the problem.
A TV tuner card
notebook
It should turn off automatically if you plug it into your computer and turn the computer on. If it doesn't, something is wrong. First thing to check is the plug that plugs into the computer for bent pins. Also check the other end of the cable that plugs into the back of the monitor. If the pins are not bent then you will likely need to take it to a shop for repair or replacement.
