I did integrated, didn't work, btw just the past day and so on after it first happened, sometimes my main display will flash weird colors, but then be fine in like half a second, and when i start up my system the startup screen is in like a letter box. A black border around the perimeter of the main screen.
The monitor that is messed up (Samsung), now says Check Signal Cable ("Digital" under it). So this is a good indication that the monitor is fine, and its something with either the cable, the adapter i have to use (VGA to DVI-I), Motherboard, or the Graphics Card.
*BUT I plugged the monitor into a laptop with switched cords and adapter, and the monitor still said Check Signal Cable, didn't do anything.
(BTW, I have a MSI gtx 660ti, supports 4 monitors, and 3 in surround.
This computer is not even a year old, and the graphics card isn't even 4 months old. the monitor though is as old as the computer.
It annoys me that I just woke up one day to see that my monitor just..didnt work. -_- no way i can buy anything new, with my mom 40k in debt i give her all my money.
