If you have an Nvidia Graphics card then on the bottom right hand side of your task bar, next to the time, it's a green icon. A Nvidia logo is displayed. Left click on it and move your mouse over rotation settings, should be set to rotate 0 degrees.
Can also access through control panel, then Nvidia control panel, then on the left menu rotate display, set it to no rotation 0 degrees.

mcdevito75 here, Your Monitor could be bad, (blown out) a monitor is just like a lite bulb. start your computer verify fan is on, verify monitor is on with on off switch on monitor, press shift key on keyboard maybe your computer is on stand by or hybirnation, also click the mouse at the screen left click and right click to bring picture to screen, if picture on monitor ok, if not press AUTO on the monitor, this brings back factory settings to your monitor. If all this fails, bring your monitor to a Radio Shack, Staples etc. for testing.
Does your tower support PCI?
Is the card PCI, and not PCIe? (There's a big difference)
If you've installed the drivers and software that came with the video card, and still get no picture, you may have a defective product. However, try this, to rule that out.
Once in your PC, and your monitor's connected, try the "Source" button on your monitor. It's possible that your old video card used analog, and your new one uses digital, and your monitor just needs to look at the right input.
If that doesn't work, and you've installed the software, you may want to contact Radeon to replace the unit. Or, return it to the store to exchange for a new one, if you're within your return period.
How do you know the monitor is the problem? Try your computer with a different good monitor. If it has the same problem then the computer is at fault. If it works correctly then the monitor is at fault. Is this a CRT or LCD monitor? If it is a CRT monitor (with a big picture tube like old TVs) it would probably not be worth repairing. You can buy used ones pretty cheap. If it is a flat LCD monitor you would need to get a repair estimate and weigh that against the cost of a new one. Anything can be fixed but if repairs are more than new what would be the point?
So the monitor buttons don't work also right? Yeah, normally you should try to adjust the brightness control first on the monitor. If that doesn't work next step would be ofcourse to check the cabling of the monitor to the computer. Try reseating the video cable from the back of the computer. If no go, then the next step is running the monitor self-test. You can do this by just disconnecting the video cable from the back of the computer, and leaving the monitor plugged into the power outlet.
All monitors has a form of self-test that it does to check the functionality, usually a picture or a color bar display on the screen or even a message that the monitor is on self-test. If it's still dim on that screen, then sadly you already have a hardware problem that may require to you buy a new monitor.
