My E-Machine T17LC-9 monitor is acting up

[Lancelot103]

My (old) E-Machine monitor says that the self check is working but is will not connect to my dell tower. I was wondering if something is wrong, or if it is just not compatible. Thanks!

Have you tried the old monitor on another computer or laptop?
