Hey there !!
I've kept the following site handy for a while now. See, I also have a Sanyo monitor, and although it isn't giving me problems now, someday I suspect it will.
When capped, the Sanyo's produce such a nice, bright crisp picture I wish all of my monitors had the same display. Having said that, I think you'll find this page at least a little helpful.
You might want to bookmark it just as I have.
