Hi, I've got a very lound buzzing noise coming from my TV when connecting my PC to the TV using the DVI to HDMI cable, Here is the detailed setup:
PC: HP DC7900 mini tower running windows 7. there is not spdif output on the motherboard.
Video Card: MSI 250GTS with 2 DVI-I dual link output, and the card is in the PCI-E X4 slot (X16 won't fit because of the chasis fan). The card has spdif input.
TV: x37sv-komodo - Sceptre
When the system started and get into winodws, there is a loud buzzing noise coming from the TV speakers even thoug I turn the volumn all the way down to mute. I am using the DVI to HDMI cable comes from the TV.
And here is the interesting poing: when the PC turns on, the TV has to be set at DVI so I can see the initial loading process (BIOS etc). But when the "start windows" stared, and a few seconds later, the screen goes blank. I have to set the TV to HDMI so I can see the screens, and this is when the loud buzzing noise starts.
And on a side note, anyone have this TV hooked up to a PC have a hard time to adjust the screen? although the manual says for PC, 1360*768@60Hz (native), I can't make it work. I have to use the nvidia's tool to adjust the screen and the final resolution is a weard 12xxX7XX.
