input not supported

My monitor just stopped working and I get the message input not supported on a Dell
l inspiron 620 desktop computer running on Windows 7. I tried safemode with networking and it is still the same message

Try a different monitor or try that monitor on a different computer you know is working.

Right now, my guess is you need a new monitor or your video card is messed up and needs replacing.

Thanks Emma.
I tried that already. I tried to reboot with lower resolution but still the same problem so next step will probably a new monitor which supports the Radeon Video card I have in there with this new dell computer.
What do you think?
