I have a samsung LE26R41B and have purchased a DVI-HDMI lead. My pc is running on a Geforce FX5700LE and i'm havin real problems connecting the PC to the tv usin the DVI port. When i try and use this connection method the picture seems to be displayed twice, one on top of the other and it flickers like mad. The only way around this is to change to a real low res and then the picture is too big for the screen . Any ideas?
