Hey guys. I just recently set up dual monitors. After some time I started noticing my right monitor flickering on and off, basically losing signal. I decided to go to bestbuy and buy my 3rd monitor and both the new monitors work fine but my old 3rd monitor still flickers on and off. I guess i need to buy another 3rd monitor to replace it? The thing is, is there a way to fix it? I wanna run triple monitors and dont have the money to buy a 4th to replace the 3rd...
