I have a dell laptop that was connected to a sony bravia TV by VGA cable and worked fine. I upgraded the TV to a sony bravia xbr43x800e that only has HDMI. Ive bought 2 different vga to hdmi converters and tried both and I get no signal to the TV. I tried the HDMI cable on something else and it works. I checked the HDMI plug with Blueray and it works. The computer also doesnt see the TV and it isnt listed in the nvidia control panel like it did with the last TV. The computer is set at native 60 hrz, 1920 x 1200. I dont know what else to do and since ive used 2 different model converters Im thinking it isnt a bad converter, any help?
