Scandoublers tend to work alot better with LCD monitors I have a Toastscan and it looks dark on my 15"CRT that I use for my A4000D so I just opened up the back of the monitor (not recomended unless you know what you are doing) and turned up the brightness from inside. The scandoublers use a fair bit of power and because of this dont always output what you need to make a CRT work right LCD's tend to need a lower signal and compensate better.
