Alright, I just lost my 22 inch LCD Acer AL2223W to failure.... it was working perfectly for a year then turned black all of a sudden. I thought it was sleeping as it usually does, but when I hooked my mac min and macbook pro it did the same thing. It turns on for a sec then off, back to black. Here is my problem, I am trying to connect my Desktop computer to my LCD tv HDMI like my mac mini is connected. Only problem is, it wont turn on. What am I doing wrong? LCD TV won't grab signal. My LCD works with my mac book pro and mac min but not my desktop. Is there a boot sequence or something I am missing to boot in lower resloution for it to work???. Card in power mac G5 is a ATI 9800 special edition.
