I have a problem with HDMI connection to my TV. When i connect pc using motherboard HDMI to Dell u2410 monitor system picks it up instantly (shows bios post screen and windows loading). But when i try to connect it to my Toshiba Tv (it's an old model but has HDMI 1.3a) it does not show anything... not bios post screen, not system loading... I've tried differnt HDMI wires. nothing helps. So any one knows a solution?
