Check your cord from the computer and monitor. If that is ok check your video card.
This is actually coming from your monitor. I am assuming you cannot get a picture on your screen. It is telling you it cannot detect any input signal. You just need to check where the monitor cable is plugged in and ensure its in the right spot.
That is the monitor telling you which of its video input ports it is seeing valid signal on and has selected to display (if more than one port has a valid signal).
This generally means that the monitor section of the unit is not receiving a video signal - make sure the jumper between the two video plugs in place. On mine unfortunately it was a dead motherboard for the computer. The monitor section was working fine - just no signal from the motherboard.
Check the cable running from your monitor to your computer. It could be disconnected, loose, or be a bad cable. If you decide it is not the cable then it could either be a bad monitor or a bad graphics card.
An HDTV ready computer monitors indicates that it is capable of accepting an HD video signal and displaying native 720 and/or 1080 resolutions.
It means it is not getting a signal from the computer. There are many situations that can cause this symptom, from the cable being unplugged to a motherboard failure to the computer simply not being turned on.
Try the monitor on another computer to make sure its not the monitor.If the monitor works on a different computer than you will narrow your search to the PC itself. If the monitor does not work in a different PC check the monitors cords and check the pins on the parallel cable, make sure they are not bended or broken if they are bended try to straightened them out.if its not the monitor and works in a different PC its your PC go to your control panel and head to power options and tweak it around.
Your connection to the nearest tower is either weak or lost. The phone is searching for a new signal.
You must also enable the 2nd monitor from within the PC's control panel in order for the system (motherboard) to "know" that there is another monitor connected.
Have you tried a different monitor? Even if it's giving an actual error message, it may just be broken. Also, it may be your graphics card; or if your using integrated graphics, they may be shot too. Try the monitor on a different computer so you know that it works. Then go from there.
If a monitor says auto processing, it means there are driver problems. To deal with this, simply remove the power cable from the monitor. Wait for a minute and plug it back in and turn on the monitor.
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.
