I am using a new Lenovo y550P laptop and having problems with the external monitor. When I plug my external PIXO LCD monitor via the vga port, I get a constant flickering. I have tried installing and reinstalling all the graphics drivers
for video card (geforce gt 240m), adjusting the refresh rates, tried 3 different vga cords, 2 seperate LCD monitors, and using different power surges with and without the laptop adapter, all to no avail. Please help!
