Two displays not working?

[cherrystar5996]

So I have these two displays - one is a Dell display (cheap one - don't even remember what type it is) and the other is a Wacom tablet/display. They've worked fine in the past - no problems at all - but after installing a new harddrive (the old one was failing), the dual screens won't work anymore. I can get one - or the other - to work, but I cannot get both to work together. Help? I changed nothing but the hard drive!

Check your cables if you use the same one to test with the second montors cable may be the issue. Are you using an adaptor? If so it could be the issue. Reset your monitor defaults to ensure there is no problems. Ensure that the multiple monitors are detected in your operating system. If all multiple monitors are detected by your operating system, you may have to enter the video card manufacturer's control panel and enable the multiple monitor configuration there. Updating your video drivers may resolve the issue.
