frequency out of range on projector

I hope i haven't tried everything yet, but it sure seems like it. I am using a hdmi converter for wii to connect to my sony projector. The projector only has a hdmi input. I know the converter works because i am able to hook it up and get it working on my hd tv. but when i hook it up either through my amp which then sends it to the projector or hook it up straight to the back of the projector i get the message Frequency out of range. I can only get the audio. I have tried changing the wii setting to 480p, but still no luck.

i tried the bluray player and it works fine, obviously no inputs on the back of it, i also tried another receiver with the same result (frequency out of range). Its obviously the projector. I am about to call sony and ask them. I don't know if buying a wii U would solve the problem or not. Kind of expensive gamble, plus 20 of the games i have are home burnt and wouldn't work with it anyway.

just got off the phone with sony and the projector will show 480 but i need to use the 15 pin jack on the back. Well that's the end of that, the projector is in my media room with wires and power in the floor. I'm not sure if i want to have wires on the ground just to play wii. I guess first thing is finding a converter to 15 pin from the wii jacks. Oh yeah, the only sound i would get would be from the little speaker on the projector

i phoned Sony and they said the hdmi plug won't see the 480p,, but i can use the yellow video input on the back of the projector. i tried it and it works.but i am now running a single video cable from my cupboard across the room to my projector. oh well,i don't play Wii that often, and i guess i could always buy a Wii U if it bothered me. thanks for all your help.
