I just put together a new PC and when I turn it on the screen just says 'No Input Signal'. I am using the monitor Acer AL2016W and the graphics card SAPPHIRE 100149 Radeon X1900XT 512MB GDDR3 PCI Express x16. The refresh rate on my graphics card is higher than that of the screen, but there is no way I can configure it because of the monitor problem and no OS has been installed yet. I also am using the motherboard: ASUS A8R32-MVP Deluxe Socket 939 ATI CrossFire Radeon XPRESS 3200 ATX AMD. I have looked for several solutions on google. None of them worked. They were things like "change the slot the RAM sticks are in", "change the slot Graphics Card is in", and "Disconnect all cables from the motherboard so it can reset". I really want to get this display working. Any help would be greatly appreciated.
