Hello, I'm experiencing a problem with my graphics card, gt 640, I recently bought a second monitor and adapter, the adapter is a DVI-I to VGA, when I plug in both monitors one works and the other monitor goes black. One of the monitors is fairly new as in year-wise LG monitor and the other is an old lenovo monitor from 2006-ish both are using VGA cables via adapters. The lenovo monitor is connected to the dvi d to VGA adapter and the LG monitor is using the dvi i to VGA adapter, am I doing something wrong? Any advice or help is greatly appreciated! Thank You!

@ i7Baby the lenovo monitor is 1440 x 900 and I have had my tv connected along with the lenovo monitor at the same time and it worked... Both displays were showing... If I were to lower the resolution on the LG monitor would it help??? The tv I plugged in at the same time said it had a res of 1334 x (something I forgot) + 60 Hz. Also the gt 640 is an evga.
