Question about Compaq Presario CQ56-115DX Laptop
IQon monitor showing no input signal but is in devices on laptop
In general, you need to select which output display to use, when you have more than one display connected to the laptop.
This can be done by pressing and holding the fn in the lower left hand of your keyboard and then pressing F4. Doing this repeatedly will switch from the laptop display to the external display to image on both displays.
Hope you may find this information helpful!

SOURCE: External microphone not working
Check first if your sound card is working properly.
My Computer >> Right click...Properties >> hardware >> Device manager >> Sound
Then go to Start >> Control Panel >> Sound and Audio Devices .........hit ADVANCED
one dialog appears MASTER VOLUME >> Go to OPTIONS >> Then PROPERTIES..........
CHECK the MICROPHONE...........Hit OK.............
This will be fixing your problem (if your sound card is working well)
