Thus, it’s quite clear that the HP monitorisn’t receiving the correct input signaldue to damaged video cables or problems with the source. Moreover, it could also be caused due to underlying issues with the monitor firmware or device drivers.
But you do not need to worry, as we have covered eight proven ways to help you fix this monitor error and bring it back to life.
What Causes “Input Signal Not Found” on HP Monitor?
