I have an Xbox 360 connected to a Philips LC4745 LCD projector using an RGB cable.
The problem is there is a constant tear line about a third of the way up from the bottom of the picture. I have tried everything I can think of to sort this out with no luck. I've tried different resolutions and connecting it via vga to no avail.
I don't think it's a projector problem since I've also tried a Philips LC5141 DLP projector and the results are the same except for the position of the tear line.
I tried connecting a friend's Playstation 3 to the setup and the v-sync problem was still there.
I don't know if it's a problem with the current generation of consoles because a PS2, DVD player, laptop or anything else I've connected to the projector has no such problems.
I really hope someone can help me with a solution as it makes movies viewed on either console unwatchable and although games are affected to a lesser extent due to less horizontal movement, it's still pretty annoying.
Many thanks,

Jimma.
